I strongly advise against taking any vehicle to North Mountain Auto. On 04/08/2026, I brought my 1996 Ford Probe GT to this shop for a water pump replacement. Dashcam footage explicitly shows the vehicle running perfectly fine that morning while it was at another shop receiving an estimate. It was dropped off at North Mountain Auto two hours later. On 04/13/2026, the vehicle was pulled into their bay exhibiting no problems, yet it exhibited severe running issues immediately after their "repair." The vehicle was subsequently removed to a neutral third-party shop via a recorded and documented chain of custody on 04/27/2026, ensuring no claims of tampering could be made. Independent diagnostics have since confirmed catastrophic engine failure, including air passing through the piston rings and a 25% leakage around the exhaust valve on Cylinder 5. Far more concerning than the mechanical destruction is the actively documented fraud and attempted cover-up. Forensic dashcam video and telemetry data captured the shop engaging in billing fraud by charging for one type of product (Asian vehicle blue coolant) while explicitly using another. Furthermore, on 04/20/2026, approximately an hour before I arrived to pick up the vehicle, the mechanic is recorded stating to the front desk that he had already lost two days the prior week and five hours that current day on the car and was "done." Twenty minutes later, footage shows them manually overriding factory settings via the base idle set screw (BISS) in a deliberate attempt to hide over 30 documented engine stalls and doctor the vehicle just enough to collect payment. This override occurred on four separate occasions. Additionally, the intake plenum was removed. There is absolutely no reason for its removal during a water pump replacement other than assessing internal damage; it provides no extra room or access and is 100% unnecessary. Both the mechanic and the shop stated they hadn't "worked in that area," claiming the damaged wires and broken clips had nothing to do with their work, which the visual evidence explicitly contradicts. When the shop realized my dashcams automatically trigger upon movement or when the key is turned, they attempted to format the memory cards twice while the car was sitting in their bay: once on April 15th, and again after hours following a "stealth" repair on 04/22/2026. This constitutes direct spoliation of evidence to cover up their actions. When I reached out via text message, they immediately denied warranty coverage, blamed the car, and then blamed me. However, until this week, they had no knowledge that the dashcam footage was NOT actually deleted. If you're going to perform such acts, you may want to research the specific dashcam to know how to format it. Just saying. I have retained a 236GB forensic data drive documenting every action taken in their bay. Now that every legal and regulatory action has been filed and is underway, I am leaving my experience here to help prevent others from suffering the same fate. Do not trust this shop with your property. Billed $2282.49 for them to destroy the drivetrain. read more

I love love love North Mountain auto!!! They fixed my ac a few days ago and I have told everyone I've talked to since how amazing this place is. They were mindful of the time I was working with to get it checked out (had to get my son from school that same day) and had it fixed in that time too. It cost the same for the fix as other places were charging just to diagnose the issue. I could tell immediately when I called that this was where I wanted to go because when I said the ac wasn't working, this was the first place to ask for context of what was going on. The other places I spoke to told me their (expensive) fee to diagnose. When I brought it in they offered a complimentary Lyft ride so I could wait at home. They texted me the repair details so I could approve it and then was able to come back just in time to get my son from school! I am so impressed at their kindness, honesty, process, and customer service! I rarely leave reviews but made a point to write this because they deserve it! read more

Scheduled an oil change the day before asked to drop it off at 12. Told me they would call me when done and gave me a ride home. They would call when it was ready. Car is a 2020 RX 350 Lexus with 63,000 miles. Everything was in perfect working condition. At 4 o'clock, I called to see how soon my car would be ready since they closed at five. They called back and said they found a crack in the oil cap which was plastic to replace, one would be $80. We researched through Amazon found 20 different varieties to replace at $16-$20 max. When called back to ask them about the $80 oil cap and why. Said to leave it on and we would take it back to the dealer to get an oil cap. They said it was to cracked put back on. They reduced the price down to $30 and would call when car was ready at 10 minutes to 6 we drove over to pick up the car, never getting a call. When shown the oil cap there was not a crack it looked like someone had burned a hole in it with a lighter. We said there was no oil leaking from the oil cap or the car we just got back from Vacation. Hence it may have been a great $50 oil change but I am so tired of Auto Repair Shop's trying blindly take advantage of sure what is wrong with their car and being aware that deals like this do not exist. We will be going back to Lexus and I will pay the difference for my car to make sure I don't have to worry about it or the repairs are false and not caused by the Repair Shop. read more

it's really hard finding a trustworthy mechanic, my brother referred them so I tried it out. The customer service is spectacular, I've never been treated this well at an auto shop. They got me a Lyft home and back while it was being worked on. They did a full inspection and showed me everything under the car that was concerning. They create an invoice with all the pictures of what was broken and repaired. Truly the best in the valley that I've found. Will refer everyone I know to them. Great guys. read more

If you had told me a few months ago I'd be writing a glowing, out-of-this-world review for a mechanic shop, I would've laughed. In my 32 years of life, I've dealt with more "meh" mechanics than I can count -- the kind that leave you guessing, overspending, and second-guessing everything. North Mountain Auto completely flipped that narrative. A few months back, they performed a thorough and completely free inspection on my car -- and I'm talking next-level thorough, with detailed photos and clear explanations. No pressure, no upselling, just honest, expert service. Fast forward to this week: my car broke down unexpectedly right after I picked up my toddler from school. I had it towed and--thankfully--got it over to North Mountain Auto instead of settling for the overpriced shop nearby. They took it in quickly, looked at it sooner than expected, gave me a reasonable quote, and had it fixed up before I even finished stressing. I had rented a car for the week not knowing how long it would take, and thanks to them, I was able to return it early and save $200. That's unheard of. This team is knowledgeable, kind, transparent, and FAST. I'm officially a customer for life, and I can't recommend them highly enough. Mechanics like this do exist -- and they're at North Mountain Auto. read more

I absolutely Love Love Love this place! After moving in the area and being on the hunt for an honest and reliable mechanic I happened to stumble upon this place via google, and I'm so happy I did. I won't go anywhere else for my car needs. I would call same day and they get me in, They work with you every step of the way, keeping you updated as they go. They'll discuss with you the issues of your vehicle and never pressure you into getting things done, and just overall really embody that great customer service both times I've been there. I'll always recommend my family and friends here and yes this is a safe space for women who have trust issues with mechanics read more

very disappointed after 5 years of going here and recommending them To all My family and friends basically they opted to loose a good customer over $103.00 dollars Car would not start after work on Wednesday and was showing check engine light ! Was able to jump the battery and to be on the safe side took it to the shop dropped the key and told the shop it would not start or go in neutral due to the safety feature on the transmission they had my Jeep all day Thursday and then called me at 4:00 pm asking to charge me $99 per hour for two hours of diagnostic testing! Then called and said it's ready I went by after paying $206.00 and picked up my car went home and parked in the garage next morning did not start again ! Decided to call Jeep and take it to the dealer again after jumping the battery ! Come to find out the batteries were both bad ! So I guess two hours of diagnostics and they could not figure out that it was a bad battery ? Paid $746 got both batteries replaced and a 3 year warranty from Jeep and then called the manager at north mountain explained to him that I was not happy with the service as my car was literally in the same condition the next day ! Asked for half of my money back to be fair to them and he said no ! Because over the past 5 years they have only profited $109.00 dollars from My oil changes ! Absolutely shocked ! They kept my money and lost a good customer at the same time ! I will be letting everyone I know in the area not to go to this shop as all they care about is their profit and not how satisfied their customer is ! Do not use this shop ! I do not recommend them at all read more

North Mountain has been my Go-To Service for about 5 years now, and wouldn't even consider going anyplace else for my 2003 Ford Explorer Truck. Not only are the service guys extremely qualified, but the Service is Affordable!! I appreciate that so much as an older woman that has to watch her Pennie's!! The Owner is considerate, friendly, and there to keep his Customers coming back!!!!! read more

My moms car was in need of repair. They were able to get it in that same day with an estimate back to us later that afternoon. Great customer service! They noticed her oil was due to be changed and they did it! Excellent communication- updated us with estimated times and kept to it! Reasonable pricing! They cleaned the car for her- she appreciated it so much. A few weeks later we had to go back for a related issue- a clamp had come loose- they diagnosed and fixed it free of charge. They were very honest and I could not recommend them enough! read more

North Mountain Auto Repair - North Mountain Auto the best auto shop!! In PHX - Auto Repair Near Me - Phoenix, Arizona

This was the poopiest smelliest mechanic experience I've ever had in my life. I suggest you stay far away!

Be honest and not pull a fast scam on new customers. If you had tested my friends battery like you said and charged for, he would not have needed to have his car jumped and taken to a Dealer. 1 star only because a star rating is needed. read more

From the first phone call talking to Stacy to driving away this place was outstanding. They took care of my check engine light, they did not make me feel they were coming up with problems that weren't there so they could make more. I really liked Stacy at the front and the guy who worked on the car. (Forgot his name) but even he was so nice. Didn't treat me like a lot of mechanic shops do. Will definitely take my cars here in the future. read more

I'm still in shock!! What amazing customer service!! I had taken my older model Infinity to these guys before and the service was remarkable. But today they came and helped me at my home out of courtesy!! It's so hard to find someone who you can trust-especially as a single person!! Thank you all again!! read more

I have decided to switch mechanics about a year ago because the other garage switched ownership. North Mountain was close to my house and had some reviews that were positive. They are really great to work with and very helpful in being accommodating to my odd hours in my work schedule. Prices seem reasonable and with some notice, they are able to get your vehicle back on the road running when promised. They are thorough in anticipating any issues that could occur in the next few months but not pushy as to what needs repaired. A good group of folks running an honest business. read more

I took my car to North Mountain Auto Repair after the last place I took my car performed services I didn't ask for and caused more problems with my car than I had before. I asked North Mountain to do a complete inspection to see what was wrong and specifically to fix a terrible squeal that the old place said was air in the fluids. North Mountain said the squeal was caused by the power steering pump. After replacing the pump and bleeding the system along with an oil filter and fluid change it cost $1516.21. It turns out the squeal is as bad as always and I feel cheated. read more

Highly recommended this place I had a coupon I found on there website for an oil change, i'm so used to other places charging large additional fees for oil changes, I didn't experience that here. Service was efficient and great and the people at the front desk were very kind. read more

We've been going to North Mountain Auto for a few years now and they are above & beyond in the shop and customer service. Nicole and Phillip run an extremely reputable business. We highly recommend them. read more

Got an ad in the mail (I live close) for a great price on an oil changed. Made an appointment online. I got there and they started on time and did not try to upsell me, like so many other places do. Nice experience would really highly recomment read more

Huge shoutout to Phillip Marcy for doing what other mechanics said couldn't be realistically done for less than 3000 or so: get rid of this awful squeak in my car. Phillip did a ride around with me and figured out it was probably my struts that were making the squeak he took it for a day figured out what was wrong and also suggested another piece of maintenance to make the right a little bit smoother My car went from squeaking all day every day when I was driving it to not squeaking at all. He did a fantastic job, I would recommend him to everyone read more

I received an ad in the mail for this shop and I'm grateful to have brought my vehicle to them. Very friendly service I had a great experience and didn't feel like they were trying to get me for my money! I dropped my car off Friday Labor Day weekend for an oil change, air compressor and catalytic issues, it was done by Tuesday and drives like when I purchased! read more

Phillip and his team were great to work with as I had service done on my Nissan 370Z. Rotors, pads and tires. Fair prices, knowledgeable and good work performed. Would go back again for any additional needs and would recommend to colleagues, friends and family. Special thanks as well for the care the took of my car treating it as it it was one of their own. Nicole in the front office was also friendly, kind and caring. Thanks! read more

Great service! I went to another Jiffy Lube nearby, but they didn't have the right oil for my car. I was greeted quickly upon arrival and had my car taken to be serviced. This shop made sure they gave me the right oil and were finished before I knew it. Will be coming back! read more

I took my car in to get the fuel pump & rear shocks replaced. I had to take my car immediately back because it was making a rattling noise by the back shocks. A week later my car completely died, they put a refurbished part and charged me for a new one. They knew I was 9 months pregnant & how important it was to have a reliable safe vehicle. They had my car for over 5 days, they tried replacing it again with the same brand refurbished part. I took the car home & noticed my car smelled like gas again My car completely died again & had to take my car back AGAIN for the third time. They had to drop my gas tank every single time to replace the fuel pump, when I took my car again they said the gas tank was cracked which is wasn't the 3 times they dropped it prior. They had my car for over 2 weeks & charged me an additional $800 for the gas tank that was not damaged prior to them doing the work. This was the worst experience I have had with a mechanic. read more

I never write reviews unless I'm really happy or super mad and in this case I'm ecstatic! They got me in same day to get new coolant and transmission fluid, they price matched me (their price was already low), and they had excellent customer service. Shout out to Nicole in the front office and the owner Phillip who did the labor and spoke to me on the phone. They also fixed the framing around my tire that was hanging/lost a screw for no additional charge. I'm beyond pleased with this place and will 100% be back. Thank you North Mountain Auto you guys are life savers! read more

ever since they changed location the service has been terrible. they kept my car for over a week and did no work on it and said that they would call me regarding it multiple times and never did. i'm stranded without my car and can't go to work as a result. i'm so disappointed. myself, my fiancé Elijah and my mother in law will all be taking our business elsewhere as well as friends we have referred. i will be advertising how bad they are around the neighborhood. i'd give 0 stars if i could read more

Brandon and his crew have worked on my car for several years now and there's simply no one I trust more with it than them. They take the time to listen and understand what issues I may be having with the car, do proper diagnoses and then fix the issue, all quickly, professionally, and most importantly fairly. I have never felt like they're trying to upsell me on unneeded services or products. In my experience, they have always gone above and beyond what another mechanic might offer, and I am confident that they can handle any mechanical problem your car might be having. I can't recommend their work highly enough. They are my go-to repair shop and the only one I recommend to friends and family. read more

Had to have a oil change, so I yelped around and found this great place! They are very friendly and honest. I love that they are very professional yet don't make you feel like you were just another customer coming to there shop. Brandon (owner) gave me a step by step of what was needed next for maintenance. Joey finished up my oil change and I was off! My car is riding great! Thanks guys! I would recommend Big B's to anyone!! read more

Brandon, Matt and the rest of his crew are top-notch. I was referred to Big B's by word of mouth, and I couldn't be happier with their service. I own a BMW, so as you might imagine, I am no stranger to spending time in automotive repair shops. Big B's now has 100% of my business. Every time I bring my car to them they are able to interpret my layman's description of the issue, open the car up, and quickly diagnose and correct the issue. The one and only time my car had an issue they could not fix due to the car needing to be reprogrammed by the manufacturer (one of the many joys of owning a BMW), they were quick to pick up and tow the car to the dealership. This occurred during a hectic time at my job, and I found myself extremely stressed trying to figure out how to orchestrate getting my car handled with the chaos of my work schedule. I genuinely can not express the relief I felt when all I had to do was explain what needed to be done and Brandon took over and flawlessly executed getting the car taken care of. No hoops, no yellow-tape and most importantly, my headache was over. The final thing I'll mention is the hospitality this shop offers. The majority of my dealings have been with either Brandon or Matt, and both of them have gone above and beyond to make me feel at home in their shop. While I never enjoy car issues, I do look forward to getting my car fixed at Big B's. Most of the time now I bring my laptop and hang out with the guys while my car is worked on, and I generally will get a bit of work done from their WiFi. I genuinely feel as if I am now in the company of friends, rather than purely a business-customer relationship. At this point, Brandon and Matt have more or less eliminated the more problematic issues I used to face with the car, so the majority of my visits nowadays are limited to preventative maintenance. read more

I have been struggling for many years to find a reliable mechanic, it's safe to say my search is over. While I have only been in for a few minor repairs, Big B's Family Auto has provided outstanding service. Kind, respectful and always willing to go the extra mile to get the job done. Brandon and his staff are always quick with a handshake as well as an oil change. With a down-to-earth attitude and great sense of customor service, this locally owned garage is the very essence of hard work and dedication, which is just what you want in a mechanic. Rest assured I will be going to Big B's for all automotive repair needs from now on. read more

Our car needed major repairs and after shopping around we went with North Mountain, who was recommended by a friend. They were amazing to work with and gave us a fair price for all the work that had to be done. They are honest and trustworthy - would highly recommend! read more

After countless auto shops I found Big B Family auto. They understand Jeeps, 4x4s and how a modified off-road vehicle should be serviced. They explained every step and what improvements can be made to my 08 Jeep Sahara. My ride is better because of Big B Auto and I'll now I'll be a full time customer with my Toyota Camery too. Honest, trustworthy and masters of auto repair. read more

Best shop I've ever been to. Highly recommend! Phillip and staff have always been very friendly, honest, knowledgeable, punctual and reasonable with price. Will not be taking our vehicles anywhere else! read more

I have brought my car here 3 times now. They are FABULOUS!!!!they always take me in and have went above and beyond for me!!! I will not take my car anywhere else.

North mountain auto is a great place to go for any of your auto repair needs. The manager phil is a great guy and makes it his personal mission to make sure every vehicle that comes to his shop is fixed in a timely manner and fixed right the first time. I highly recommend North Mountain Auto And Fleet repair for all of your service needs. read more

I have taken my vehicle to North Mountain Auto on multiple occasions, and have referred several friends to them! Everyone has been super happy, and I love the complimentary pick up and drop off service, so I can have the work done while I am at work! I continue to send friends and family your way read more

Absolutely best mechanic around. My car is 8 years old and I'm bad at maintaining it, shame on me. Consequently, it had numerous needs. I took it to Phillip and he went through my whole car and gave me a complete diagnostic report from small things like my wipers to large problems like my transmission. I was embarrassed that I'd been such a neglectful car owner, but he put me at ease and didn't treat me poorly for it. Working with my financial restrictions he let me know what was an immediate need, what could wait a while and what could wait longer. With his recommendations, I've taken my car in a few times to work through the list of needs. Each time he is professional, friendly and prompt. He is always honest and works with integrity. I completely trust his recommendations and never feel taken advantage of. That's a hard thing to come by when taking your car to the mechanic. So many try to just b.s. someone who doesn't know better and scam them into things they don't need or want. But he doesn't. Every repair he has made has been amazing. My car is back to her young self and I'm so thankful to Phillip. He has since worked on my daughter's car and he's currently working on her boyfriend's car. He goes above and beyond to make the correct repairs and not waste your time or money. He really knows what he's doing and takes pride to do it right. We won't go anywhere else, period. read more

CROOKS! Turned in to the BETTER BUSINESS BUREAU! Sold us a POS truck that they claimed was such a great truck and it lasted 31 days before the engine blew out of it and then wanted us to pay another $2500 for an engine! And for Brandon, the owner, I don't really care that you own a business, I care about the fact that you ripped us off and now we are out $4000 on a truck that doesn't run! Screw your business, I could care less about your business! Karma will come to you! They were so friendly until the truck went out and then they acted like they didn't know us! I don't know how they sleep at night knowing that they are completely screwing people over while making a profit! We turned these guys into the Better Business Bureau! And never once did they offer to rebuild the engine at his cost! That is what he told the BBB! That is a complete lie! Because they are liars, i really don't expect them to tell the truth at any time. So stay away from Big B's, they WILL rip you off! Ok as Brandon the owner said that it was a private sale and had nothing to do with his business, BUT HE IS the OWNER and even though he told us he stands behind his product, and had a reputation to uphold, he did not have much to say when this POS broke down! He wasn't standing behind his sale then! He just wanted us to come back so he could charge us more money for him to work on it and just keep making money off of us! Also, social media falls under "freedom of speech" so tell that to your lawyers! DONT BUY FROM THESE GUYS! COMPLETE CROOKS! read more

Imagine making a phone call and pulling into your mechanic friend's yard an hour later and just cheering him on while he fixes it right then and there! Yay for Brandon and Joe and others at Big B! read more
