GM Experts
For more than 25 years Cory Taylor has specialized in working only on GM cars and trucks as a Master GM Factory Certified mechanic. He is also a Master ASE Certified mechanic. After working at a large Phoenix Arizona GM auto dealership, he started his own GM auto repair service in Tempe, AZ. Cory does auto repairs on GMC, Cadillac, Hummer, Pontiac, Buick, and Oldsmobile cars and trucks.

He is skilled in diagnosing and repairing GM vehicles for far less than you pay at dealerships. Brian was knowledgeable, straight up, pulled no punches. Even after i picked up the car and a/c quit again, he was ready to check it out and if was something they missed was going to make it right. Turns out i just needed to replace a $16.00 relay myself.

Great shop, my first time there. It's hard who to know who to trust with your vehicle these days, especially older performance cars. Brian was great, he was patient, thorough, and always kept me up to date on the progress. Good value and I will definitely keep using this shop and would refer to family and friends. Thanks Brian!

Brian was very helpful and honest . The repairs took longer because of extended warranty. Brian is good at negotiating with them for your benefit.

Service was prompt, and my AC works like a charm before the triple digits start. And have a 1 year warranty on the work I had done! I give them 4 star ⭐ because they seemed a little pricey but I didn't have time to shop around so that's my fault.

I was very impressed with GM Experts. I am from Idaho visiting family in town when I found my Air Ride Shocks were shot and brakes were bad. They were able to get me in on New Years Eve and have it done same day so we could head out early the following day. Their pricing was best in the valley and I called a lot of folks. I would highly recommend GM Experts. They were fast, good service, and rates could not be challenged.

How have I not reviewed this place? About a year back I had to replace an engine in my 2011 Equinox and these guys took care of me big time. They worked with my warranty company to just about eliminate my out of pocket and today they helped me again. Brian worked with this same warranty place to ensure my AC unit was replaced and working properly going forward. I appreciate these guys and always recommend them to family and friends. Go here and support honest mechanics with an attention to detail!

I April of this year 2109 I had them seal all engine compartment oil leaks. They sealed the oil pan,timing cover and replaced the pressure power steering hose for total of over 2 K. I pointedly asked them to make sure they only put 4 quarts of oil in the engine as that is the called for amount by the manufacturer. However upon returning to NY driving 2450 miles my rear main started leaking and upon checking I found that they had put in 5 quarts of oil which I believe caused the rear main to start leaking. Also After another 1 k miles all of a sudden I lost all the power steering fluid. It seems

Just had my truck serviced at GM Experts for a knock sensor replacement. And the difference is like night and day. Very happy with the results as always.
The technician that worked on my truck went above and beyond. He did all this extra stuff that I was not expecting. He topped off all my fluids, did something else cool to the throttle body, plus he made my door open correctly! (I bought my truck with a dinged door, it would always make dent-like noises when it opened and closed) But NOT anymore!
This is the 4th or 5th time bringing my truck to GM Experts, and it was the 2nd "Big" job

What a pleasure to do business with people who really seem to care about the customer. I just bought a little old ladies 2001 Seville with 46K miles. AC was doing strange things and I was picturing a second mortgage on the house to get it taken care of. Cory and team found the problem immediately and repaired for an exceptionally reasonable price with a help on other issues on the car that they also took care of quite reasonably. I strongly recommend these people. They really are experts.

We took my wife's '08 Corvette to GM Experts for leaking CV boots and a couple of other minor things. Cory and his team replaced both half-shafts, flushed the brake system, and found the cause of a tingling sound coming from one of the spring-loaded exhaust hangers. We were very pleased with their communication, level of service, and pricing. No drama and no surprises. Thank you!

They charged me 1/3 less for parts and labor , than everyone else in town. When I went to other places, they couldn't depict where all of the noises my Cadillac was making, was coming from. GM Experts did!!!! Thanks guys!!!

Please, please, please do not let the business name trick you. I took my GM vehicle here for my last oil change and after reminding the owner via yelp messages and in person, he still used unapproved engine oil (I have a diesel that requires DEXOS2). It did not appear that he even understand the difference. Now my vehicle is in for a 3rd round of repairs for emission issues probably caused by the high ash oil he used. Be careful. More expensive does not always mean better, but cheap will always mean cheap!!!

My BMW was a giant expensive German pain in the a**....but thankfully GMExperts and the owner Corey assisted in fixing up the monster on multiple occasions - for WAY less than 1/2 the price the dealer had quoted us.
Highly recommended!

Purchased a 02 deville with the Northstar motor. Turns out that motor has a design problem. It had a cooling problem and failed a block test(that means the head gaskets blown) ! Was not ready for that. The dealer said $4100 to $5000 to fix!!! The car had only 55 k on it but ..that much...no thanks. I went online and found Cory and GM experts.Called them and Cory answered. Talked to him and he filled me in on the design problem. The next day I went down and met him, firm hand shake, looks ya in the eye set up a time and dropped car off. The price was 1/2 what the dealer wanted. The car is real clean
