I am so glad I found this excellent auto repair shop! The service I receive from Jason and Rudy continues to be superb, therefore, I honestly decided to post a second review. I needed Jason's expert opinion on a used car I was considering purchasing, and he provided great advice and professional courtesy. I am grateful to Jason and Rudy, and will continue to bring all my cars here for service! read more

This is the best honest mechanics I know I've been there twice and they tell me I need it use 3 quarts of oil and later on change my oil God bless you guys you guys are the best very honest I'm glad I ran into you guys read more

I am so glad that I decided to come into G's shop. Jim did my oil changed and fixed my flat tire in 30 min. Amazing and honest people. G made me feel like I had nothing to worry about while my car got taken care of. I will definitely come back for anything else my car needs. read more

Stopped in today because I needs an oil change, originally G quoted me $35 for a synthetic oil change which I thought, holy cow.. That the cheapest price ever. Come to find out, that price for a synthetic blend (still a great price) and not for full synthetic which was still only $60! G honored the price she quoted me which NO other mechanics would've done. I ended up getting my air and cabin filters changed by her while I was in. If I lived in the area, I would come here with no hesitation especially because of the service G provided me. She was great, if I could give this place 10 stars I would. It's hard to find a person to take your car to for repairs that you can trust, instead of having to worry about hearing, "oh hey by the way, your windshield wiper fluid is low so it's probably a good idea to replace your engine." Thanks again for the great experience G! read more

G at G-Tech and her mechanic Jose were more than helpful! They were honest and genuinely willing to help. They were able to get my car up and running in no time at all. I will definitely be going back to G-tech for my future automotive needs. I would definitely recommend that you check them out if you feel something is wrong with your vehicle or even if it is just routine maintenance. They make you feel like family. I got my car repaired by them after another mechanic didn't want to help. You could not compare the level of customer service I received from G. If you want a pleasant experience go to G-tech! read more

I needed tires for my suburban n everywhere I went it was way over my budget. My dad had recommended G Tech to me n when I finally went I was mad at myself for not going sooner. . affordable prices n professional service. I enjoyed my experience. read more

G Tech Automotive has great customer service! Went there to patch a tire and they did a phenomenal job. Very honest people! Would 100% go back! read more

It's always kind of confusing to deal with car problems because as a regular person you don't know anything about what your car needs or doesn't need, so you kind of have to trust the mechanic you're working with. It's unfortunate that this industry is full of people who take advantage of that to rip you off. That will not happen at G-Tech. I took my car in to have my brakes serviced, and the owner G offered to drive me to work (just a couple of blocks away at a nearby hospital) and she even let me know she could drop off my car when it was done. That level of thoughtfulness and customer service alone would have me coming back. When I dropped my car off she quoted me a price for the brakes and let me know they would do everything to save my rotors (whatever those are) and save me a few bucks if they could. When I went to pick up my car, the price was exactly what she had quoted, and they were able to save me money on my rotors (I guess it was a risk because I had been driving around with screechy brakes for a month and a half.) She was also kind enough to get a quote on new tires (they are BAD, according to literally everyone that has seen my car recently) which was a full $400 less than what the assholes at the dealership were quoting me. I will DEFINITELY be coming back here. I feel like my car was take care of, and G is honest and really wants to save you some money. Don't hesitate to come here if you're having any kind of car trouble or for regular maintenance. I know I'll be coming here from now on for all my car needs. read more

It feels really good to find an honest, knowledgeable staff and trust me i ben looking for awhile. I had a conversation with Ms G the owner that made me feel at home. Jason took the time to explain to me the parts cost and labor (havnt had that done before) and labor was reasonable. You have a loyal customer. Thank you G read more

The most honest repair shop you could ever go to ever! They are so brutally honest with you about your repairs and no hidden fees or costs. All the technicians working here are helpful and really care about there customers. I will 1000% recommend this shop to anyone and everyone. You don't find many good business like this that truly care about their customers and have pride in what they do. Thank you all so much ! read more

Great service. Nice people. Fair price. What more can you ask for?

G was awesome and they were very professional, fast, courteous, and most importantly, not expensive! All services there were half of what I would pay at my local Toyota dealership. I am grateful. Nice to have a trusted source in the neighborhood. Keep up the great work, team! read more

I am new to this area and had already spent 3k at a few mechanics in the San Dimas area to fix my car. The car was still having idling problems, so I took it up the street from Aunt's house to G-tech in Upland. The owner, G, was professional, knowledgable and honest with me. I thought the repair was going to cost me an arm and a leg, or that my car being 14 years old was done. But G's mechanic fixed the problem for A really reasonable price and by the next day. I'm going to give negative reviews at the San Dimas 76 station on Via Verde and the Chevron on San Dimas and Bonita for ripping me off. I'll never go there again. But G-Tech is the bomb! read more

I met the owner "G", she is very professional and informative on the service I needed. She was very honest about her service. I look forward to calling on G-Tech for my future auto needs. read more

It's my first time at G-tech. Impressive customer service, very honest and friendly people. Reasonable pricing. I was looking for a permanent mechanic and it looks like I found it at G-TECH. I spoke with other customers that had nothing but good to say about GTECH and the employees that work there. I highly recommend giving them a try if you need any automotive repairs or services. You might get some free cookies out of it like I did as well. read more

I was referred to g tech by the guy at auto zone when I pulled into their parking lot overheating in my 1998 BMW. David said these guys are good and honest. They sure we're!!!!.I was so upset, and they calmed me down and fixed a bad radiator housing unit, all for 172.00...now mind you, they could have said it was way worse like a blown gasket,but they didn't take advantage of me.. I would send anyone there!!!! Absolutely top service. read more

Very good service. Every time I come I my oil change fast and for a very good price. Probably the best place I've been to in California. And I'm a native. read more

Great place for all your automotive needs, been coming here with G since she took over from super trucks. Doesn't up sale me on useless junk, only the essentials to get my car running in close to perfect conditions. read more

got my alternator "rebuilt" here failed couple weeks later took it to another shop installed new alternator for less than they charged to rebuild it and now no more alternator issues felt kinda ripoff! read more

My husband and I own a small business and we have been taking our vehicles to gtech for service for the last couple years. They are honest and always let us know if something needs to be replaced right away or if it can wait. I highly recommend gtech as an honest and trustworthy mechanic. read more

Terrible customer service they seem to prioritize other cars and lie about the time it'll take to fix your car

I love this place the owner G is very honest and knowledgeable, they have reasonable prices and always friendly. I've sent several of my family members there and they have all been happy with their service. read more

Great place honest people competitive low rates on brakes and other services I would gladly recommend to others and I'm a hard person to please but these guys got it done very professional. read more

Great place to get your car repaired! G the owner is an awesome person! Very professional and neat shop. A true one stop shop for auto repair, and window tint! Went in there for brake pads and no complains at all. read more

Call out to Jason at G-Tech! So professional yet fees like you've known him for years! What a sweet guy! They had my car in and out of there in a jiff! Great prices and they are willing to work with you! Kiss those dealer overinflated prices goodbye and bring your car here! read more

So glad that I found this place and that it's walking distance from my home! Way cleaner and more organized than your average auto repair shop. It USED to be Super Truck until about like a year ago when they took over. It's now a full-service repair shop and store, so basically an all-in-one type of deal. Oh and they're open on Saturdays too (until 2), which is a huge plus. Got quoted on some fuel injector replacements recently and it was cheaper by just a few bucks than some other shops I contacted. But even if it cost a little more, I would still come here instead for their friendly service, attentiveness, and transparency. read more

Took my Black Jeep Wrangler into their shop this morning not knowing exactly what to expect. I have for unknown reasons, been experiencing the dreaded "death wobble " in the steering of my Jeep? When I pulled in, I was met by 3 very helpful employees. Once I explained the issue I was having, they started to "troubleshoot" the problem. Immediately, the found my aftermarket steering stabilizer bracket lose and missing a clamp. Before I left my Jeep with them, I was told they would fix the faulty stabilizer bracket and double check and tighten all the other front end suspension parts. After a couple of hours, I returned to G-Tech to find my Jeep parked out front of the shop. Oscar, one of the mechanics there, came right over and explained the work and repair they had done. He told me that what they fixed was more than likely the cause of my steering problem. As I removed my wallet to pay for the work performed, Oscar informed me that there was no charge!! My jaw dropped in disbelief!! I told him that I have to pay for something and again was told, "don't worry about it !!" I have never be to a shop where something like this happened. Impressed is an understatement!! I am thankful that there are still good honest businesses and employees out there like those at G-Tech. Needless to say, if I ever need work of any kind done on my vehicles, I will be returning here. This shop is strongly recommended, especially for those who have an off-road 4x4 vehicle like me, and are not sure where to take it for repairs!! Hats off to this place. A great business!! read more

Sorry to be the first to give this place a 1 star review but let me explain myself. Sunday night I stayed over at my friend's place (I live in LA) so I could fix my car in the morning since Foothill Blvd had a plethora of auto repair shops and decided on G-Tech since it had great reviews. My car has been really loud the past couple of weeks when accelerating and I just wanted to get that taken car of. The people at the shop diagnosed the problem (a hole in the exhaust since it was a lowered car that I admit I sometimes carelessly hit when going through dips and bumps). They said it'll take 2 hours to fix so I left and came back more than 3 hours later to find that my car still wasn't finished. It wasn't a problem so I waited some more. When I finally got my car and paid, the mechanic said I might scrape "a little" but I thought "that's fine, that comes with having a lowered car" so I left. We drove not even 10 feet before bringing it back because it was constantly scraping ON FLAT GROUND. It does not take a genius to know I cannot drive home in that car and how can they even allow me to leave like that truly astonishes me. We told them there is no way I can drive like that, not only will it annoy me but it will only cause another hole (aka the reason I initially came in). They said I can leave it overnight and they'll try to fix it (but no guarantees) but the best thing I can do is raise the car so I won't have this issue anymore which I accepted and agreed to reluctantly since I do not live in the area and therefore cannot go home for another night but I can't drive home in that car anyways so it was my only option. They said they'll work on it first thing in the morning. Great. The very next day (Tuesday) we called to see when we can pick up the car. They said it'll take the whole business day. When we arrived around 3:45 pm, they weren't even working on my car! I understand maybe they were booked but I simply did not feel prioritized as a customer. I was supposed to have my car Monday but couldn't as a result of their doings and they did not even try to fix my car ASAP knowing I don't even live in the area so this was a complete inconvenience (I wasn't prepared for the sudden onset of El Nino and was forced to wear leggings and jelly sandals for 2 days! Talk about misery). It was as if if I didn't physically show up, they wouldn't have even started working on my car. And when I got the car back, all they did was rebend some pipes to prevent the scraping and did nothing else that was promised. Granted, they could not locate the parts needed but it seemed like a simple task they could've done sooner instead of making me wait 2 days to simply fix a hole in my exhaust. read more

I love this place!!! Took my vehicle there for a front differential repair.. The price that I was quoted was the price I paid.. Although the Owner "G" said there could be additional charges once they opened my differential up and inspected it.. Fortunately for me it did not need additional repair, which they very easily could have said and I wouldn't have been the wiser... This is just an example of G-Tech being an honest, trustworthy repair shop. Furthermore I dropped my vehicle off in the morning expecting to not get it back for at least a day or two. I couldn't have been more wrong... My vehicle was done by lunchtime... This is a honest, clean, professional shop with excellent customer service.. I strongly recommend this shop and will continue to go there for all my automotive repair needs.. read more

I recommend all, who care for there vehicle to Gtech. Manager was very helpful and knowledgeable. Went in on my lunch break and I was in and out in less than 30 mins -Jimmy read more

I Went with a few buddies from my car club to install a muffler 2 weeks ago. Gotta give my high props to G-tech automotive, they where great! The owner and mechanic who hooked us up where very honest, professional and sincere. I'm gonna continue coming to G-tech to have more work done on my ride soon. If u need work done on your car i highly recommend G-tech Automotive. read more

This is a very honest and genuine business. I've been to a lot of shops especially in upland who just want to gauge you left and right. Over here at G-Tech, Jason and G were two of the best people I've ever come across. Jason himself was very kind and extremely helpful when I first dropped my car off. When I came back to pick my car up, G herself was honest, smart and genuine. The whole vibe from the shop was just great. Great service and great people. The integrity of this shop is beyond what anyone could ask for. I was recommended from my aunts friend and I will literally recommend this shop to anyone and everyone! read more

It is very rare to find an auto shop that takes pride in customer service and giving the customer the best price. This shop is a prime example of how an honest auto shop should be. I will definitely return and recommend to others. read more

best place to go!!! jim & lupe are awesome and honest!! they tell it like it is and don't screw you over the only place i take my cars now!!

What I needed done to my vehicle was a radiator change & also an oil change. Having my radiator not functioning properly there was no way for me to take it to my fathers mechanic at his dealership in El Monte. I went around getting estimates on the service i needed and I finally arrived at G-Tech. Lupe, the owner of the garage, knows how to take care of her clients. Her approach and professionalism made me feel comfortable & secure that I was going to get the service I needed. After discussing the issues with my vehicle with Lupe, her mechanic Jim gave me a walk through of the entire process and what needed to be done. It was the man's first day and I thought he had been there for years, a true professional. From the client service to the service needed done on my vehicle, G-Tech has gained another loyal client for many years. Thank you Lupe & Jim! read more

This place is awesome! I moved into the area 2 months ago and went to G-Tech on recommendation from several friends. My car's transmission had been acting up so I figured I needed a fluid change. I was seen immediately and the owner and mechanic both recommended that I NOT get my transmission's fluid changed in order to avoid ruining its integrity. Most auto repair shops would have just changed my transmission's fluid without a second thought, taken my money, and sent me on my way. I was so impressed by their honesty and professionalism that I asked them to change my car's oil since it was in need of an oil change as well. They made me feel welcome and pointed out a few other issues with my car that I should take care of soon, but they did it without pressuring me to get the work done immediately and gave me a very reasonable quote. I will definitely be bringing my cars here from now on! 5 stars! read more
