I am writing this review to warn future customers about my unacceptable experience with Affordable…read moreTransmission and Auto Repair Center regarding an ATRA nationwide warranty repair. Background and Initial Service: My vehicle's transmission was rebuilt a few months ago by a different authorized ATRA shop. Due to a recent move, the original shop authorized me to bring the car to this affiliate location, a 30-mile drive from my new home, for a warranty diagnosis. Upon drop-off on 11/18/2025, the front desk employee immediately became cold and dismissive when I mentioned the words "warranty repair." The Issue & The Refusal to Diagnose: The problem is specific and reproducible: when the car is cold, driving downhill causes the transmission to shift into what feels like neutral. Pressing the gas results in rising RPMs but no movement, forcing me to shut the engine off and restart it to re-engage the drive. After two days, I received a call informing me they could not reproduce the issue and were refusing to work on the car. I explained to Miguel that the condition requires a cold start and a specific downhill coast, asking them to try again or keep the car longer. He flatly refused any further testing, stating they were done with the vehicle. Integrity Violation and Fraudulent Documentation: Since they refused to honor the warranty, I requested a written reason for the denial of service, which is standard procedure. Miguel went to review my paperwork. When he returned, he presented a form and demanded I sign it before he would provide any written explanation. This form was an explicit waiver where I would acknowledge that the issue I claimed was not present and that their testing proved my claim was false. I refused to sign a document that was contrary to reality, as the transmission issue is demonstrably still present. The Threat and Escalation: Because I refused to sign the false waiver, Miguel refused to give me any written denial and escalated the situation. He told me he wouldn't help me anymore because I was "not a nice person." When I stated I would write an accurate review of this unprofessional experience, he raised his voice and began threatening me: Threats of litigation. Explicit threats of physical harm to myself and/or my property at my home. Threats to contact my employer to have me fired. I immediately took my keys and walked to my car, with Miguel following me out of the office, continuing to curse and issue threats. This behavior is far beyond poor customer service; it is menacing, unprofessional, and a direct failure to honor the ATRA warranty program. The shop refused to perform due diligence, attempted to force me to sign a false legal document, and threatened my physical safety. Avoid this business at all costs.

The staff was professional, straightforward, and didn't try to upsell anything unnecessary. They explained everything clearly and got the job done efficiently. And honestly, the prices were even better than expected -- especially for the quality of work they delivered.

The BAR association of California has been trying to stop these guys unprofessional business practices for years but they keep changing their bar number and owner information/shop location so they keep getting away with scamming people. Please don't let them steal from you like they did to me. They refuse to uphold THEIR WARRANTY and refuse to reimburse for the negligent work they did to my vehicle. Please do not take your car to any AAMCO that Haroon is operating(used to be on Division street in Lancaster is now at Trevor Ave in Lancaster)Haroon is a complete waste of skin and his business operations are negligent and he will leave you with an empty wallet and a broken vehicle. DO NOT MAKE THE SAME MISTAKE I DID. If I could leave negative stars I would. This place is an absolute joke. They said my vehicle was ready for pick up with no leaks and runs just fine when in fact it barely starts, leaks oils like a siv, and they cut wiring to my headlights, they 'replaced many parts' but refuse to give me the paperwork showing they purchased new parts to put on my vehicle, they refuse to give me work orders from the shops they apparently use to prove they worked on my vehicle. Please do not let Haroon scam you. This shop does faulty work and is highly unprofessional when it comes to the customer wanting their vehicle to be working properly after $20k spent to a scammer.

Since we were…read moreplanning to drive back home the next day, we were pretty stressed about getting it fixed in time. We reached out to several local repair shops, and CARS Cristian's Auto Repair was the only one that returned our message that same evening. They got us scheduled first thing Saturday morning. The part we needed wasn't easy to find, but they went above and beyond calling business after business until they tracked one down that could be delivered the same day. The part arrived around 1:30 PM, and they quickly got it installed and had the AC running like new. What makes this even more impressive is that they were supposed to close at 12 PM that day. Instead of turning us away, they stayed late to make sure our car was fixed and ready for the long drive back through the Vegas heat. Their dedication ensured we made it home in time for work and the kids' school on Monday. Truly outstanding service, professionalism, and kindness. If you're in the area and need a trustworthy shop, I can't recommend them enough!
