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

My husband and daughter took her 2016 Jeep Cherokee Latitude here to get the catalytic converter…read morereplaced after being quoted $550. They arrive and then get charged $800, I called up there to inquire why the big difference and they said it was because they couldn't "rebuild" her existing one and had to order a new one. After talking to my mechanical, he informed me he has never heard of a catalytic converter being "rebuilt." I feel transparency is key, they should have told me last week when I called for a quote or parts and labor, it would start at $550 but could go up. I am very disappointed as I have sent other customers to them for work to be done, don't know that I will continue doing so.

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.

I dropped my vehicle off because the air conditioning went out on 15 September 2026 in my Chevy. We…read morecurrently live in Louisiana, but were visiting in Texas on the way out of town for a road trip. They estimated that my repair time would be approximately 3-4 hours. It took a little over 6 hours to repair the vehicle. They charged just over $1,100 to replace just the compressor. I left for a road trip to Colorado the next day from Mansfield. Approx. 5 hours into a 12-hour drive, the AC stopped working again. Turns out the condenser failed as well. At the time, I was not aware that they didn't replace the whole unit, especially with the price they charged. I called, and the shop said they would get me in as soon as possible, but they aren't open on weekends. I had to drive the remainder of the drive in summer with no AC, and the entire 12-hour drive back to Texas after our road trip was over. We waited until Monday because they aren't open on weekends and brought in the vehicle first thing Monday morning. Had to call off work to wait around for them to fix the AC. Approximately 2 hours later, the shop informed us that the AC was repaired. It was still late morning, so it was relatively cool. About 30-45 minutes into the drive, we realized that the AC was still not functioning properly. Upon calling and returning to the shop again, they informed us that they didn't actually repair anything; they just pressed the AC button, felt cool air, and determined that the AC was functioning properly. It was still broken. We left the vehicle with them the same day and overnight to fix it the next day. They informed us they couldn't diagnose the issue or start repairs on Monday because it wasn't "hot enough" outside. They never called us with any updates during all of these repairs; we were always the ones who had to reach out for updates. On Tuesday, they didn't give us an update until 3:30 in the afternoon after waiting around all day again and having to call off work. They informed us that the condenser failed and that they didn't replace it before, and wanted to charge us another $ 700-ish to replace the condenser. I informed them that I was displeased with the delays and service that we'd received so far, and that we couldn't miss any more work (we live out of town). A service rep told us, "I've had my car repaired many times, and I've never missed work over it; there's Uber and lots of ways you could figure out how to still work". In a respectful and calm demeanor, I informed the rep that I would be giving a negative review online for my negative experience with their business, and he could not have cared less. The overall poor communication, slow service times, disrespectful comments towards my wife and me, and failure to properly diagnose the problem and solve it on multiple occasions led to this poor rating. Highly recommend avoiding this business at all costs.
