Exhaust repair service near San Rafael, CA

Mike was great! We were in need of a last minute repair, and they were able to get us in and fixed within hours.

My truck wouldn't pass the smog test and you discovered a broken cigarette lighter. I had been plugging a dash camera into it and that was causing the fuse to mess up.

The guys here are always straight forward. Good prices and I don't feel like I'm paying for services that I don't need. I've been taking my personal car here for awhile and the company I work for gets their services done here. John S. Antioch, CA

I love going to Clayton Valley Auto Service as Jeff and all those who work there are friendly, knowledgeable and do a very good job. When I had a check engine light Jeff's dad told me right off the top that it could be 4 or 5 different things and they would start out with the least expensive until they found out what the trouble was. I'm still driving that van around 5 years later. I really appreciate the great service they give. They are really great for routine maintenance, and wonderful when I have emergencies.

I took my car here for what turned out to be a simple, small electrical issue. Instead, Carlos told me I needed a fuel injection flush - one of those things they upsell you too when you go to an oil change place. Only this one cost over $300! Carlos assured me that the problem was resolved. I ended up stranded at the side of a freeway two miles away. I had to get the car towed at a cost of over $150! The solution was easy, took 10 minutes, and cost me nothing at the place I towed it to. When I called Carlos to tell him I was stranded at the side of the freeway because of his poor workmanship, his attitude was dismissive, condescending, and unhelpful. He proceeded to tell me that he doesn't guarantee that his workmanship will fix the problem. Really? Imagine if your doctor treated you that way. Basically, he took my money and did nothing. I get the feeling that this place once was a good shop, but someone got greedy and dishonest. To be certain, Carlos is a good talker. He seems sincere and knowledgeable. But the emphasis here is on SEEMS.
