Our family's Ford Explorer required a water pump replacement…read more I visited several local auto shops to obtain quotes and was shocked, disappointed, and discouraged at the prices I was being quoted for the work my vehicle required ($5,000-$7,500) Shame on me for not reading Yelp reviews before wasting my time visiting other auto shops. I read the many positive reviews for Hye-Tech Auto Repair and decided to visit them. Upon entering, I was greeted by John (owner) with a friendly, "Welcome, how may I help you?" I explained that my Ford Explorer needed a new water pump and a few other items that other auto shops had advised me would require repair or replacement. While John looked up a few items on the computer to provide me with a quote, he introduced me to his son, Harry, who happened to be in the office. Thirty seconds later, John provided a quote that was $3,500-$4,000 less than the other shops. I could not believe it. John explained that he makes his living and succeeds in his business through repeat customers, and he does not believe in gouging customers for every last penny. He also shared that when he retires, his son Harry will take over the business, and he wants to leave Harry with a solid foundation of loyal repeat customers. It was then that I knew I could trust John and his son Harry. John went on to explain that replacing the water pump on a Ford Explorer was a 10-12 hour job, as it was an internal pump requiring numerous engine parts to be removed to reach it. This was the same thing all the other shops advised me. John suggested that I leave my vehicle, and he would perform a full inspection of the engine and contact me before doing anything to it. I agreed and left my vehicle. The following day, I was contacted by John, who advised me that the water pump did indeed need to be replaced, as it was the source of the constant leaks of the water coolant. I left my vehicle in John's shop for three days. During this time, John or his son, Harry, contacted me numerous times to keep me updated on the progress of my vehicle and also to point out that mechanics had discovered two or three very inexpensive items (under $50.00) which they recommended replacing, which I agreed to have done. All in all, I was and am extremely impressed and satisfied with everything about this shop. I spent much less money to have five different issues repaired on my vehicle at Hye-Tech than what I was quoted to replace my water pump alone by every single shop I visited prior to coming to Hye-Tech. John and Harry are very friendly, honest, and trustworthy. They are also very knowledgeable and experienced, and they offer GREAT customer service and communication. This is my new go-to shop for any issues involving our family vehicles. Thank you, Hye-Tech Auto Repair, for a very positive experience.

I opened a Yelp project to try to get my transmission serviced. The dealership wanted to charge me…read more$1300 for this service. Yelp projects are one of the best things I've ever experienced. It's nice to see you can get quotes at the touch of a button on your phone. This morning, I had time off, so I headed in to get my service done. I did not have an appointment and that did not seem to matter. I arrived first thing in the morning at 8 AM and ask if the service could be done. Harry was an exceptional young man, he took me in with no problems, no questions. He said they could do it this morning. I told him I would have to wait. He had no problem with that either. Prior to bring in the car in this morning, as I said, I used a yelp project and had several people reach out and give me quotes. After looking at all the yelp reviews I decided to give this place a try. I am super happy that I did. This place is a hidden gem, excellence, service, quality, and value for what you receive. There are not very many shops where you could feel comfortable and put your trust in them. As I spent time in the lobby, I was able to see customer service on the phone and customer service entering the facility. Every customer that walked in, seem satisfied and was treated with dignity and respect. I highly recommend this place if you have any automotive questions whatsoever.

My car needed both low beams replaced, an oil change and a tune up. Matt was quick to provide me…read morewith a quote that was reasonable. Scheduling the appointment was easy. Brought my car in, went over some paperwork and was told I'd be contacted once the inspection was complete. Sure enough Matt called me to let me know there were some items found during inspection and which ones needed to be addressed right away. After agreeing to the updated quote they got to work. I came back to the shop prior to being told my car was ready, and I think there may have been a delay in getting parts needed (dropped the car off at 9am, wasn't done until 4pm). Other than that, the quoted price is what I paid, there wasn't any pushing to buy a service that wasn't needed. I will definitely be bringing my car back for the additional work needed.

I requested a quote through Yelp and my request was sent to multiple auto shops. I chose this…read morecompany based on location and called ahead to confirm they could do more than just read basic codes. I had already done my own diagnostics and knew the car was running rich. I had ruled out the upstream O2 sensor, catalytic converter (both new), MAP sensor, and fuel injectors. I explained all of this to Matt before bringing the car in. He assured me they could perform deeper diagnostics with their equipment. After dropping off the car, Matt called and told me they had "confirmed" exactly what I had already told them, and that the next step would be pulling spark plugs--for an additional fee. At that point, I decided to go elsewhere. What I don't understand is why I was still charged the full $85 diagnostic fee, plus a $4 hazardous materials fee and $3 shop supply fee. Plugging a car into a diagnostic scanner does not generate any hazardous waste--no fluids are drained, no chemicals are used, and no parts are replaced. There's nothing about a basic scan that would justify a hazardous materials charge. That kind of fee typically applies when disposing of things like oil, coolant, or other regulated waste, none of which occurred here. In the end, I paid $92, wasted time and gas, and learned nothing new. The most concerning part was Matt admitting he didn't even know spark plugs would need to be checked as part of further diagnosis.

5 Stars - TMC Auto Repair in Diamond Bar (aka the place that actually gives a damn)…read more Let me paint you a quick "before and after" picture so funny it hurts: Scene 1: Midas in Diamond Bar, 3:50 PM I roll up with a driver's window that's basically on permanent vacation (stuck halfway like it's trying to ghost me). The guy behind the counter doesn't even glance at the car. Doesn't ask a question. Just grunts, "Yeah, it's the motor." Me: "Cool, wanna pop the door panel and confirm? I'll pay for the diag, takes 10-15 minutes tops." Him: refuses to move, refuses to look, basically treats me like I'm trying to sell him oceanfront property in Arizona. I left wondering if "customer service" is now Latin for "get lost." Scene 2: TMC Auto Repair (literally two minutes away, same day) I used to go to this shop years ago when it had a different name. Now it's TMC and let me tell you -- it should be called TLC because that's exactly what they give you. Walked in frustrated and Martin greeted me like a human being who mattered. He listened to my Midas horror story, laughed with me (not at me), and said, "Let's actually look at it." One of his techs pulled the door panel in like 8 minutes and... drumroll... the motor was bad and there was a broken plastic piece in the regulator (exactly what I told Midas Guy, who apparently moonlights as a psychic but forgot to charge his crystal ball). They got the window temporarily working until the new part arrives, didn't overcharge me, and treated me like I've been their customer for a decade (because I basically have). Moral of the story: Midas Diamond Bar just lost a customer for life in under five minutes. TMC gained a customer for life in under five minutes. Martin and his crew are professional, honest, fast, and actually enjoy fixing cars instead of playing "guess the problem from the lobby." If you're anywhere near Diamond Bar/Walnut area and need work done by people who treat you like family (the good kind, not the dysfunctional Thanksgiving kind), go see these guys. 10/10, will be back the second that part shows up -- and for every oil change, brake job, and random rattle from now until my car retires. TMC, you have my undying loyalty... and my window now goes up AND down. Magic. Show less

As soon as I reached out, they got back to me almost instantly, which was a huge relief.

Just a few days later, they were at my doorstep, ready to get to work on my car. The whole process was incredibly smooth and quick - they had everything sorted within about an hour, all from the comfort of my own driveway!

Decided to take it in on a Friday in the morning. Checked my wheels and told me I just needed the front brake pads and rotors replaced. The back was still good. Sigh of relief somewhat. They were able to get the pads and rotors replaced for little under 3 hours. Time went by and they were updating me during the whole time. Great service and team here. Will definitely bring my car back in to get other services done. No issues whatsoever with the new pads and rotors.

PROBLEM: ALIGNMENT ISSUES, CUSTOMER SERVICE, ACCOUNTABILITY…read more When I first tried to leave a review, my account was somehow blocked from posting specifically for RTM, while I could still review other businesses. I contacted Yelp, and by coincidence, the representative I spoke with was also RTM's Yelp rep. He said it was strange that I couldn't post only for RTM. After I explained my situation, he advised me not to leave a review and instead take the matter to small claims court--which I did. During the hearing, the judge seemed to understand my side, but the ruling ultimately favored RTM. Despite being advised not to post this, I'm sharing my experience here because the situation still doesn't sit right with me--especially given Yelp's controversial review practices. On 10/1/25, my rear right adjustable control arm snapped. My car has aftermarket wheels, tires, and suspension components, so a precise alignment is critical to ensure proper fitment without rubbing the fender. I initially went to TM Auto (located across from RTM) for the control arm replacement. After installation, TM took my car to RTM for alignment. I specifically asked them to match the rear right alignment to the rear left, which was set at -2.8 degrees. When I went to pick up my car, I immediately noticed the rear right wheel did not match the rear left. The camber was visibly off. I pointed this out to the technician, but he insisted the alignment was correct and that there were no machine or human errors. After repeated requests, they put the car back on the rack, but instead of rechecking, two additional technicians came out and dismissed my concerns with questionable explanations: "Toyota made the fenders uneven." "Your control arm is made in Taiwan/China--what do you expect?" Despite putting the car back on the rack, they never rechecked the alignment. They simply removed the car and stood by their original claim. With no resolution, I had no choice but to drive the car home. Because the alignment was incorrect, my tires rubbed against the fender the entire way. The next day, I found heat damage, paint cracking, and visible wear on the fender. I came back the next day to talk to Richard (the owner) hoping he would recheck everything, but it was apparent he was "too busy"--despite clearly having time to talk with other customers and then continue working on another car, while ignoring me. I waited outside RTM for over an hour trying to speak with him. When the TM Auto manager asked if he had seen the damage, his response was, "Yeah, so what?"--with no concern at all. After is when I left, and was forced to go to another shop to realign--more driving, more damage done. I used a camber gauge and measured -2.8 degrees on the rear left and -2.0 degrees on the rear right. To confirm, I took the car to my trusted shop, Chewerks in La Habra, where they verified the rear right camber was indeed -2.0 degrees and did not match the left side. Their measurements matched mine exactly. Because RTM refused to recheck or correct their work, this improper alignment caused damage to my car. The rear left side tucks properly, while the rear right sticks out about half an inch, which led directly to the rubbing and damage. I had clear documentation and evidence, but the court still ruled in RTM's favor. I chose not to appeal to avoid spending more time on the matter. A nearby body shop, Cenco Auto Body, quoted over $1,800 to repair the fender (with another shop giving a similar estimate), confirming the extent of the damage. What could have been a simple recheck turned into a costly mistake. Despite everything, RTM did not offer any compensation or attempt to make things right. Seeing RTM's highly rated Yelp profile made their response even more surprising. They're quick to take your money with a smile when things go well, but when issues arise--as in my case--they deny responsibility and make no effort to make things right (In my case, they didn't take money directly, but a receipt was given to TM Auto, and I had to pay TM Auto--which is the same as paying RTM directly). TM Auto went as far as offering RTM to help cover the repair costs, but RTM still refused. TM Auto didn't have to step in for someone else's mistake, yet they still tried--that says everything. Richard (the owner) had my contact information through the small claims process, yet he never made any effort to contact me--even before we went to assigned court date. After what happened, I'm relieved I didn't bring my other cars first--especially since those cars are of higher value. It seems RTM has many satisfied customers, along with a smaller number of unhappy ones. Hopefully, you don't end up in the latter group like me. FWIW: Following the incident, I contacted Hunter to verify when RTM's rack was last calibrated. Abel (rep) advised that its calibration was set to expire later that month. This raises the possibility that their rack may have been out of calibration.
