I went to this auto shop to get a second diagnostic on my car after my original mechanic replaced my transmission for $4,200. I was referred to this shop by my son-in-law. When I picked up my car from my original mechanic after the transmission was replaced, I noticed it was making strange noises, felt very sluggish, and lacked power. I went to Green's Auto Shop and spoke with Jim, who told me the mechanic wanted to keep the car for about 10 days to perform a thorough bumper-to-bumper inspection. Jim later reached out and explained that the transmission was slipping badly, the engine fan was loose and causing the rattling noise, and the strumming noise indicated additional repairs were needed. I explained to Jim that I had paid over $4,200 to my original mechanic for a used transmission. He informed me that if I had come to him first, he could have installed a brand-new transmission for about the same price. I am very disappointed that I spent so much money only for my car to have the same problems--and even more. I truly appreciate Jim and everyone at his shop for helping me. I will definitely be returning for any future repairs. Thanks again Jim & Green's Auto. read more

Years of excellent service--Greens Auto Tech always delivers with no surprises! Greens Auto Tech in Upland is absolutely outstanding. Jim and Sandy, the owners, run their shop the way every business should be run--with honesty, care, and professionalism. I recently had both my 2014 Toyota Tundra and 2012 Lexus IS 250 serviced, and as always, the work was handled with expertise and attention to detail. There are never any surprises here--just quality service I can count on. I've been a loyal customer for many years now, and I can honestly say I trust Greens Auto Tech completely. Having mechanics who are this reliable and genuinely care about their customers is priceless. Jim and Sandy set the standard every business should aspire to, and I couldn't recommend them more highly! read more

This review is based of the fact that they would not accept customer provided parts. They explained they couldn't provide warranty for customer provided parts which I already knew because that's common sense. If I was willing to acknowledge they wouldn't provide warranty they should've welcomed the work. I'm extremely familiar with mechanic work and could've done the job myself but I twist a wrench for a living and don't feel like doing it when I get home. The only reason I believe they wouldn't accept customer parts is because they wanna mark them up. read more

I went to Green's Auto Tech for the first time today off of a recommendation from my brother and I wasn't disappointed! The staff was super friendly and accommodating fitting me in their busy schedule before a holiday weekend. They were honest about what was needed for the job and did not overcharge me for any unnecessary work. I actually ended up spending less than I thought I was going to going in. The team kept me updated on the status along the way and I got my car back in record time! I will definitely be going back for any car related issues! read more

Excellent customer service, excellent and speedy diagnosis and repairs. I highly recommend Green's Auto Tech.

My a/c was not working in the summer and I went in circles with Honda during lock down on whether or not my car was under warranty. They couldn't tell me if it was until months later after I hit the miles that placed me outside of warranty then slapped me a bill of 3k. Well. I decided to take my business elsewhere. It was through recommendation that I found Green's Auto Tech. The front staff is absolutely sweet, professional, and pricing was VERY reasonable. I left the shop paying way less than what Honda quoted me. I've had one oil change so far. No hassle of replacing more than what is needed. It has been great :) read more

I found this place as an installer for Airlift Airbag suspension for my truck I use for towing. Once they installed the suspension I noticed the compressor kept going off randomly at all hours of the night so I notified them that there was a leak within a week of install. The leak caused my brand new trucks batteries (has 2 linked not just one) to die. After AAA jumping me and buying a mobile battery jumper I took it in for them to look at and fix. Their solution? To charge me full price for 2 batteries and labor. These clowns thought I would pay another $500+ dollars after they caused 100 percent of the issue. Called Airlift and notified them to not allow this shady place to represent their name. I'm currently suing this company for damages and loss of time for making me deal with this crap. Wouldn't piss on this shop if it was on fire. $1900 on bags that still don't work $500 on new batteries $250 on a mobile battery jumper for a 3500 ram dually (2020 year) $400 loss of wages for a day read more

Again Greens hit it out of the park . Truck broke down on the freeway and of course I had it towed to greens auto upland ... diagnosed as fuel pump and possible MASS air flow sensor, of course if most shops say " possible " you can almost bet you are going to need one I appreciate the honesty of this shop and they continue to earn our business. I did not need a MASS AIRFLOW SENSOR, the only shop my family will use read more

When's the last time your mechanic talked you out of a service? Jim and Sandy Green did just that years ago when they thought I didn't need what I was asking for. Years later my family and I wouldn't take our cars any place else. Greens are fast efficient and fair, more importantly, you can trust them! read more

I highly recommend! They're friendly & fair, nice to feel like you've found an honest mechanic that doesn't charge an arm & a leg!

KEEPS GETTING WORSE. Wow, no one can fess up for making a mistake here. Anyone notice the pattern goes 1 star or 5 stars for these guys? I brought my car in 3 times for the SAME issue that began with a timing belt going out (which does call for serious repairs). I grew up in the car industry; myself, my brother and my dad all concluded that during my valve job someone failed to removed the cylinder head properly thus damaging the bottom end. The first day I started my car after the job was done a GIANT plume of white smoke came out of the exhaust (which persisted everyday thereafter) and a check engine light. I took it back to Green and brought my brother where we ran through every possible scenario - Green denied there being a liability. All trust was out the door after that so I took my car to another shop only to find that the fresh spark plugs done by Green were already oxidized. I must have put another $1500 dollars into this f***ing GREAT car trying to save it AFTER spending nearly $3000 at Greens. Even the timing belt COVER was installed incorrectly. THEN when I had a valve job done I also asked them to please rotate the tires and check the brakes. I got an estimate for $375 to replace the pads and calipers and machine the rotors. I wasn't happy with their price (or prior work) so I took my car to another mechanic. He called me later asking for the key to my wheels, since they are after market, and when I told him where it was, he said it was the wrong key. APPARENTLY when I asked Green's to rotate the tires, they switched my key with someone else's and initially refused to bring the key to the other mechanic. Eventually they did, but NO ONE called to APOLOGIZE for the mistake. Now the kicker... the other mechanic informed me the problems was not the calipers, but that the pins were merely rusty, and needed some lube. No one investigated the actual problem, they just "replace" everything at the consumer's expense. So my total from the other guy? $189.08 By the way, a week after my valve job was complete, my check engine light came on AGAIN. read more

I have been going to Green's Auto Tech for several years and always feel confident with their knowledge and service - I walk out the door knowing they took car of my car and any problems have been taken care of without "overselling" me with unnecessary repairs (which has happened to me at other repair shops more than once). I highly recommend Green's Auto Tech. read more

Gave them a second chance even though last time they didn't tighten lug nuts properly and tire fell off on the freeway. Dropped car off at 8 am. Was told they'd look at issue and call me in an hour or so. I called back 4 1/2 hours later to check for update. Was told everyone was at lunch so I said I'd just come and pick up my Jeep. Got a call 45 minutes later from owner saying jeep was ready. Never got an estimate or anything. Picked up jeep. Was charged $110. Nothing was fixed (AC fan not blowing properly ) read more

Just had a major service done today and as always they did a great job and are honest about what needs to be done they won't tell you that you need something you don't need. I find the pricing reasonable and they are honest. I don't take my car anywhere else. read more

Greens automotive tech has always provided professional service. We have been customers for over tens years. I wouldn't go any else.

My family has been coming here for years. They've fixed everything from my '92 Jeep Wrangler, to my Ford F-250, Honda Civic to my Ford Focus. New cars, old cars. They have you covered. And sandy is great, best customer service! read more

I have found our new mechanic! We've been going to the same automotive business for 30 years. It's 30 minutes away, which produces some challenges. We've been putting off finding a new mechanic for some time. It's hard to know who to trust. On the advice of our neighbors we tried Green's Auto Tech. They were welcoming, transparent about every repair, professional, and HONEST. Very thankful to have found their business. read more

Known and referred Green's for a number of years, cars, and situations. Everyone I've ever referred, as well as my own experiences have all been positive. You can trust this mechanic, 100%. read more

As a registered Professional Mechanical Engineer with past motorcycle racing experience I know a thing or two about motor vehicles and public safety. I have known Mr. Green for more years than the negative-posting respondents have been alive (maybe 2x longer). I have also discussed the negative allegations with Mr. Green and can say that it appears many significant details were left out considering the past origin and service duty of the vehicles in question ( hurricane total loss and beat-up street racer). In my opinion, these children have grossly misrepresented their issues and bitten the hand of a generous person who was trying to help them out. Nevertheless, I have referred many friends and family to Mr. Green over the years with zero complaints and many complements. Mr. Green is running an honest, family-owned business which is very reasonably priced, and stands behind his work. Green's is where I send my elderly mom and dad to get their vehicles serviced and would trust no other with their safety. read more

Excellent service as always! Fair charges and efficient repairs! My whole family goes here and you should too! Great family owned business that has been in Upland for years. Support local businesses. read more

This place is great! I needed maintenance on my company Truck and was referred to Green's Auto Tech. They have excellent customer service and their prices are fair. Jim Green was extremely knowledgeable and guided me with an honest opinion of what kind of maintenance my car needed. I highly recommend this place. They will be taking care of all my vehicles from now on! read more

I would like to give a "Shout Out" to Green's Auto Tech for their Outstanding service!! We have always had nothing but the best experience with them.

Great service! Recomended a great spot to eat. In and out for an oil change less than 30 minutes. Highly recommended.

great service. Had a service truck go down with bad transmission and they got it repaired and up the next day. Once my vehicles get out of warrantee, we go to Jim Green. read more

5-star review! The staff are very professional and honest. I went in to have the AC actuator fixed in my Kia Sportage. I told them my quote from the dealership and they were able to cut that price in half. They were very accommodating and quick to get my car back to perfect condition. They also rotated tires and changed the oil for me. I'm very particular about where I take my car. I will definitely be back. read more

Seriously so satisfied! Took my car into a different shop and was quoted $1800 for something that greens auto tech fixed for $250. I was so thankful I tried to leave extra and they wouldn't accept it. Amazing service! I'm so happy I brought my car here read more

Crooks. Took my Ford here a few years back, and I am damn certain they didn't do a damn thing on it. When I took it back to have them look at it, because it was running rough after this supposed tune up, they were going to charge me 100 to put it on the lift. Scumbags. read more

Always treated like FAMILY by Sandy and Jim! They take very good care of us and our cars! Don't need a 2nd opinion, trust them fully! Thank you! Michelle T read more

AWFUL AWFUL AWFUL!! DO NOT COME HERE! Chuck is so horrible. My girlfriend tried to get here car inspected and they tried to make her pay 186 for doing NOTHING! Literally nothing. She made her appointment at 8am and they did not contact her for 6 hours stating what was wrong with the car. When she dropped it off she signed NOTHING stating it was going to be 120 to "evaluate" the car. No contracts were signed and he didn't even verbally say a cost to look at it...wtf? Anyways, so the car had been in the shop for hours when my gf called Chuck on the phone and he said they are just now looking at it (about 6 hours later) and will give her a call in 20 minutes stating what was wrong... one hour later still no call. She called back and he was giving her major attitude for no reason. So, 2 hours later I dropped my girlfriend off to pick up her car and he says her total is 120 for inspection and that he "fixed" her engine light for another 70?? Greens never had our permission to fix that for an extra $70! They had never called and confirmed or had her blessing to do something for a cost.That is so messed up! She was in tears. College students don't have $186 to throw around! We came back and said we need our keys because we were not aware of the cost, and had signed NOTHING (no paperwork or contracts like how a normal business runs)! Chuck at the front was giving us major attitude again and tried to play dumb because he knew he was wrong and what they did was illegal. He told us to never come back, and I quote he said the words, "Don't ever come back here again." Yes, he truly said that to our faces...and guess what buddy... we will never ever will. Of course he told us to never come back, he knew he was scamming us and felt embarrassed... it's a defense mechanism. I felt as if he treated us even more awful because we were girls, too. Too bad we know A LOT more than you assume, Chuck. He was so incredibly rude and condescending toward us throughout the whole experience. The nerve of this guy is an absolute joke. Change your business, change the attitude. Please stay away from this place. This is our second horrible experience. Awful customer service and awful business. ALSO, we went to get a free evaluation at another place AND Greens INCORRECTLY diagnosed the car! Greens said it was something WAY more expensive than what the actual problem is. Greens does NOT know what they are doing! So sad this is a business that scams people, honestly. I don't write reviews but I am so upset. -5/10 experience in every way possible. read more

Being a women I always worry about being taken advantage of when it comes to cars. I mean I have no idea when it comes to what's going on. My brakes were squeaking and it smelled like I had a fuel leak so I brought my Audi in to be looked at. Jimmy was so nice and took my car and called me promptly the next day. He let me know my problem was due to a recall on my car and it could fix it but he recommended that I try to get it fixed at the dealership first. The dealer fixed it under the warranty and Jimmy saved me $900! Also he let me know my brakes were fine after others told me I needed them replaced. So refreshing for someone to be so honest. Sandy in the front is great too. Definitely recommend them to any looking for honest car repair! read more

Quoting the last and only reviewer. "They are very honest, reliable, affordable mechanics. They came recommended by a friend of mine and I have never been disappointed in their work or service. They will not try to swindle you or blindside you like others and they are very friendly and accommodating." Let me tell you a story. The names and items will be changed because the victims did not want to complain because they know the people that swindled them. Victim number one had a problem with his oven. Went to Reds oven repair to get it fixed. Mr Red said "this is your problem and I will fix for this much. He fixed. Victim paid took oven home. Problem was still there. Went back to Reds. Mr Red said OH I am so glad we fixed the problem because it made the real problem obvious. I will fix it for this amount. Victim sadly paid and took oven home. It seemed ok. One month later oven missed up again. Something different. Victim went to Reds who diagnosed the problem and gave an estimate to Victim who paid and took oven home. Problem continued so Victim went back to Reds who said I am so glad we fixed the first problem because it exposed your real problem. I will fix it for this much. Victim now feeling like he was being taken reluctantly agreed and paid the amount. He took his oven home, A couple days later the oven breaks down. One of the parts that was removed in one of the repairs breaks off and damages the oven badly. Victim calls Mr Red who says bring it in if it was anything we did we will take care of you. Mr Reds checks oven out and calls Victim with the following story. It was not anything we did. It just happened. I will fix your problem for this very large amount. Victim has had enough. He repeats the entire story above to Mr Green..... I mean Red who finally maybe has a touch of remorse or maybe even gulp conscience tells Victim bring your car.... I mean oven in we will repair for you. Part 2 of this story will follow shortly read more

Another great job by Greens! These guys really are good.

I've been going to Green's Auto Tech for 14 years and have always had the best service. I trust them entirely to do a good job with my car and provide the right service needed. read more

My son is a USMC stationed in Camp Pendleton. He had a 1993 Toyota truck and the engine went. He was going to scrap it but the body and interior were still great. As a Pennsylvania resident I knew the value of that. I had Greens Auto put a new engine in and then I flew out to California and drove it 2500 miles back. Zero problems. It preformed and ran great. My experience with Greens was 100% professional from start to finish. Highly recommend. read more

Fantastic Job as usual. We take our entire families cars here. Wouldn't go anywhere else. Honest and very skilled Mechanics!!! Thanks Again read more

Excellent customer service and fair prices!

They helped me get a better deal on the new engine and got me back up and wheeling in my Jeep quickly. read more
