I was hoping I just needed brake pads for the front and hopefully not all 4 wheels at the time. They were very responsive and the quote was comparable to other places, if not better. 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.

It is SO difficult to find a mechanic you can trust; when you find one, you should never let go…read more The two people I spoke with, David (owner) and Enrique were so transparent and communicative with their services, pricing, and explanations that I quickly felt at ease discussing my car issues. Situation: a few weeks ago, my car broke down in the middle of the freeway. David stayed open an extra 30 minutes after closing so I could tow my car and leave it overnight in his shop. When I arrived, he was warm and welcoming as if I hadn't just delayed his workday by half an hour -- on a SUNDAY no less! I can tell integrity and diligence are very important to him: the next business day after performing diagnostics, he determined my engine had seized. David could've easily made a quick buck by charging me for a total engine replacement, but instead he called me immediately to explain that my repair could be covered under my manufacturer warranty and advised me to try going there first. I was already appreciative by that point -- but what sealed the deal was realizing his whole team shares this integrity and dedication to service. Later that week, I called Expeditious Auto Repair to inquire about other maintenance services. Enrique picked up and was just as kind and patient as David was, explaining which services I requested they do and don't provide. Never once did I feel like they were trying to upsell me OR rush me off the phone. Ironically, this guaranteed that I'll be spending all my money here for car maintenance from now on!
