They replaced My catalytic converter with the promise that it was for a California. When I took my…read moretruck to get Smog checked in California, I found out that it wasn't for California and had to spend another $300 to get the right one. I called Collins to see what they could do for me, since I did not get what I paid for and the answer was. No, it's done and nothing I can do for you. A shop like them should at least offer partial refund or something to make a customer happy. They must not care about their customers. Would never go back or recommend anyone else to go either. That's not even to say they over price their service. Good luck everyone and stay safe! God bless you all

They typically need replacement anytime after 80k miles (we had 128k) but I was not prepared for the major expense and a reschedule. Long story short, I was in a bind and explained my situation (time, money, and my daughter needed the car) to Mike; he did a few preliminary visual checks, squeezed me into his tight schedule, quoted me significant savings and also gave me a AAA discount, finished by the end of day, and provided me a loaner.

The shop diagnosed a solenoid block failure, along with leaks, and performed repairs costing over $3,000. Immediately after the repair, my vehicle exhibited new issues, including grinding sensations and heavy idling, which were NOT present before. Concerned, I called AAMCO on January 14, 2025, at 4:39 PM MST, reporting these issues and requesting an inspection under warranty. Your representative dismissed my concerns, suggesting it was the catalytic converter, and told me to call back if further problems occurred. I was not advised to stop driving or bring the vehicle in for an inspection. Shortly after, my transmission failed completely, and AAMCO is now demanding $5,238.64 for a transmission rebuild, despite failing to fix the issue in the first place.
