I rarely post public reviews, but the public and insurance carriers need to be aware of how Fix Auto Anaheim handles quality control, post-repair safety complaints, and basic documentation.
Act I: The Premature Release Following a collision on May 22, 2026, my 2020 Toyota Sienna was remanded to Fix Auto Anaheim through Mercury Insurance for repair. Up until the accident, the van had zero transmission or drivability issues. Repairs were originally scheduled for completion around June 22, but I received a call on June 8 stating the vehicle was fully restored and ready for pickup.
Act II: Dismissed Complaints & Undocumented Repairs The moment I drove off the lot, the vehicle felt wrong, and the radio stopped functioning properly. I turned right around and returned it the same day. Management immediately tried to brush it off, claiming the issues were caused by "aftermarket equipment" a completely unsupported claim given the vehicle's clean pre-accident operating history. I was told to come back the next day since it was 4:45 PM and the technicians went home for the day.
I returned the next day. This time, a technician removed a side panel, took me in the back and showed me damaged wiring components that were never mentioned in my original repair plan, and did a quick 5-minute fix. Relying on their implied professional expertise, I left with the car without thinking anything of it. However, I later discovered this physical intervention was never documented on a supplemental estimate or added to my repair invoice. Which created an even bigger disaster with Mercury.
Act III: Catastrophic Highway Failure Less than 10 days later, on June 18, the vehicle suffered a total transmission failure on Interstate 5. It lost all driving capability in live traffic. Obviously was a massive safety hazard and had to be towed off the highway. When contacted that day I was told their computers were down, they basically washed their hands of the situation, stating body shops don't handle mechanical repairs. And they checked the codes (I have a feeling they did not check for codes or just cleared the codes and gave me the car) While I understand body shops and mechanical shops have different specialties, I had reported drivability concerns the exact day I picked up the van.
Act IV: The Evidence (Forensic Mechanical Teardown) I had the van towed to an independent licensed facility, where an official inspection and complete transmission teardown were conducted. The diagnostic findings were severe:
Stored Fault Codes: Diagnostic scans revealed a flood of transmission and torque-converter clutch failure codes (P0740, P0741, P0745, P0775, P2713, P2714, and P2756).
Teardown Evidence: The teardown revealed normal fluid levels alongside extensive internal destruction, burnt friction material, scored machined surfaces, and severe heat discoloration across the clutch drums and valve body.
The Cost: A $7,208.05 replacement estimate.
The Bottom Line I am not making an unqualified legal declaration of causation here. That is for the forensic mechanical inspection and insurance adjusters to finalize. What I am calling out is Fix Auto Anaheim's failure in their duty of care.
Did they perform pre- and post-repair diagnostic scans as required by standard industry protocols?
If codes were active, did they clear warning lights without diagnosing the underlying hydraulic/solenoid issues?
Why was damaged wiring patched off-the-record without formal documentation?
Their refusal to take initial complaints seriously left me stranded in a nightmare tri-party coordination gap between the body shop, insurance, and a mechanical shop.
Never depend on a collision center to be transparent about your diagnostic codes. Moving forward, I recommend spending $20 to buy an OBD-II code reader on Amazon. The second a Check Engine light pops up, plug it in and take clear, time-stamped photos of every single fault code before dropping your car off at a body shop. Having your own photo evidence creates an undeniable paper trail, preventing shops from claiming fault codes were "pre-existing" or sweeping critical diagnostic warnings under the rug. read more
