I discovered Quantum Mechanix probably 10 years ago when we first moved to Mansfield. We had an…read moreissue with our Tahoe and someone I trusted gave us a great word-of-mouth recommendation. Tommy just came through for us again. My son Eric was driving the old Tahoe and started noticing a coolant leak. He diagnosed it as a water pump and we gave Eric the number for Quantum. Tommy took it in, diagnosed it as a shot water pump and gave me a quote with options for replacing with an original Chevy part or a less expensive aftermarket that he knew to be reliable. Frankly, the quote was hundreds less than I expected. I am a fairly decent mechanic and would gladly pay his quoted price. He got the work done the day he was able to diagnose the problem. On time, exactly as quoted and functioning perfectly. I have recommended Quantum to friends for a decade and they all agree that you get honest work done right at a fair price. Everything you need in a mechanic shop!

If you're looking for an honest mechanic who knows what he's doing, look no further. Took my 2006…read moreMonte Carlo SS to the local Arlington Chevrolet dealership figuring since my car is a Chevy, they'd know the most about it. Engine wasn't starting immediately after turning the key. They performed their analysis and recommended a new starter and battery cables, for which they wanted to charge me $1,400+. I previously had the MC there for the same problem and, after $400+ in analysis charges, it was a $20 gas cap. Wanting a second opinion, I scheduled an appointment with Quantum. Due to their high volume of work, I had to wait 2-1/2 weeks, but the wait was well worth it. Tommy, the owner, looked at the battery cables and starter and said there was no problem with them. However, apparently some General Motors vehicles have this starting problem. Not enough fuel is getting to the fuel injectors when the key is turned. He pressure-checked the fuel pump and found it to be the problem. Rather than spending $1,200+, he showed me how to ensure the injectors have enough fuel so the engine will start on the first turn of the key. I've had cars serviced over 50+ years and Tommy is the first mechanic that took his time to fully explain the issue and the solution. He knows what he's doing and most importantly, he's honest. You can't go wrong with Quantum Mechanix.

They had two other clients there when I got there but they managed to look at my car in less than 15 minutes. Not to mention the guy managed to figure out my cars problem quick as hell. I like the fact that i didn't have to ask to show me what was wrong they showed me and let me know. Overall the service he is impeccable, speedy and affordable& reasonable. for what I got done. Would definitely recommend it's a little hidden but a gem

Completely out!! Under E! Light on!! I looked and none had leaked on the concrete. I went and asked about it and they said they don't check gas for inspections so I asked why it was like that and they said they did not know and smirked. They mentioned maybe my odometer and I got it checked and it was not my odometer! They gave me some gas(which I think was bad gas btw) and it was maybe 3 inches of gas in a hand held gas tank. Then they just said to leave they can't do anything. I barely made it to the gas station! I think they might have done this to someone else too who I saw come back 5-10 min after their inspection. Overall very angry and disappointed! There is no way they did not steal my gas! My tank is fine and so is my odometer, I had gas when I got there and not when I left. I even got an oil change and they saw nothing wrong!

I have a 2000 Toyota Sienna Van that my wife purchased new in November 1999. Walnut Creek Auto…read moreClinic has done all of the factory recommended service on it. We have made many long trips with the van to the East, West and Gulf coasts, Colorado, Wyoming, Austin and San Antonio. We have never been stranded on the road. The time just arrived for major service and parts replacement and I thought that it would be a good idea to take it to the Toyota Dealer for the work. When I took in for an estimate, they quoted a price that far exceeded the value of the car! I brought it to Walnut Creek Auto Clinic and Chris quoted the work at less than half of what the Toyota Dealer quoted, using all Toyota parts. Mike, an ASE Master Technician at Walnut Creek Auto Clinic completed the work to my satisfaction and the van is performing perfectly. I am preparing to take it on a 3,000 mile road trip to NM, AZ, snd UT. I have been impressed with Walnut Creek Auto Clinic quality service for the past 20 years and I have recommended them to my friends who have been equally satisfied. My children and grandchildren use Walnut Creek Auto Clinic to service and repair their vehicles.
