They were super kind and helpful! Although they couldn't fix my car (it's a newer vehicle and it…read morewas an issue that had to be handled by a dealer), they didn't charge me for the diagnosis and were very kind in explaining the issue!

This is one of the first negative reviews I've ever written for a business, and I'm doing so after…read moremuch careful consideration because although I feel truly wronged, I dont want to make trouble for anyone. That said, having just made the first of many credit card payments for work I never would have had done given the full scope of what my vehicle needed, I feel compelled to prevent this from happening to anyone else. While the actual work done here seems fairly competent, the diagnostic process seems about as accurate as playing darts blindfolded. I brought my car in because it was creaking misfiring, and the check engine light was on. I told them that I believed my engine mounts were worn out and that I also needed a diagnoses for the misfiring. They told me that the cause for the misfiring was likely that my spark plugs and ignition coils were worn out, because that usually happens around 100k miles and my vehicle was past that. I agreed to have them replaced along with new engine mounts, to the tune of $2,600. I was told that after this my vehicle would be like a totally different car. The very next day, my car misfired again and the check engine light came back on. When I brought it back, they informed me that they don't have any way of knowing this fo sure, but I probably actually had a blown head gasket. I brought my car to a different mechanic shop who did a full and complete diagnostic from bumper to bumper and took photos of everything wrong with the car- from a blown head gasket to a leaking transmission to almost completely worn wheel bushings and a host of other problems totaling over $8,200 in addition to the $2,600 I had already paid at Red Rock Auto. Had I known this in the first place, I never would have paid $2,600 on a doomed old van that needed almost $11,000 in work done. I had to buy a new van and that $2,600 would have really helped with the down payment. I'm tempted to say that I feel duped, but I don't think there was any malice or fraud going on- just general laziness or incompetence in the diagnostic process that very negatively affected me.
