I took it over there a second time and got charged $320.90 because ac was still super hot, they said they recharged it and put dyed for leak detection. Ac still did not work. Told me to come again. Did not come back, went to millennial auto repair and they fixed it same day, 2 hours, for $250.

I first discovered this shop when my wife was working at the school across the street from it. She…read moresaid that she had heard good things and, since we were new to the area, started going there for our service and repair needs. Like others have stated, Paul, Mike and the rest of the crew are PAINFULLY honest and forthright; they won't go into any repair unless they explain what needs to be done, in detail, and if the repairs are worth it compared to the value of the vehicle. An example of their honesty: I thought that the neutral safety switch on my 2001 Jeep Wrangler was bad so I bought the part and went to Paul's to have it installed. A few hours later Paul called and said the issue was fixed and that it was nothing more than a dirty connection, which was cleaned and solved the problem. He gave the part back to me to return for a refund when he could have kept it and charged me for installation. My wife has also take her car in a couple of time for minor repairs and they were done FOR NO CHARGE!!! Where else can you get this kind of treatment? Paul's shop is so honest, reliable and reasonable in their charges that I usually just drop off my vehicles and tell them to fix any issues that they discover, knowing full well that they will never jack me around. The only issue that I have is that they are not open on the weekend or holidays, in order to give the crew time off and family time, haha! But, that's the kind of family oriented business that I want to deal with. I cannot recommend this shop highly enough and you'll be extremely pleased if you go there!!

I brought my vehicle to Thunderbird Automotive Specialist with a fully functioning cruise control…read more It was working perfectly the day I dropped it off. When I picked up my car, the cruise control was no longer working. When I brought this to their attention, I was met with skepticism, as if my concern wasn't valid. That was frustrating, especially since I know my vehicle and how it was operating prior to service. They asked to keep the car for further inspection, which I agreed to. A couple of days later, they informed me the issue had been "fixed." However, when I asked what the problem was, I was told it was the cruise control switch. What raised serious concerns for me was what came next. When I asked for documentation or a repair record, I was told there was none--because the mechanic had paid for the part out of his own pocket. That explanation simply does not sit right. If a repair was performed, there should always be documentation--regardless of who paid for the part. Transparency is basic professionalism. The lack of paperwork, combined with the fact that the system was working before my visit, strongly suggests something happened while the vehicle was in their care. More disappointing than anything was that no one took responsibility, and no apology was offered. Mistakes can happen in any shop--but honesty and accountability matter. Because of this experience, I will not be returning.

I strongly advise against taking any vehicle to North Mountain Auto. On 04/08/2026, I brought my…read more1996 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.

Scheduled an oil change the day before asked to drop it off at 12. Told me they would call me when…read moredone 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.

If something needs replacement, they explain why. They actually talked me out of repairs and upgrades, which I didn't need. Their prices are reasonable but work can take awhile. This is understandable as these are old cars and they have to track down the parts. They can even fabricate parts that aren't made anymore and not available. At times, you may have to wait a week or two to get a part, but then it only takes a day to do the actual work. Their shop is full of classic cars being repaired/restored from the humble, like mine, to the high end ones I dream about.
