Engine repair service near Union City, CA

DO NOT GO THERE PERIOD!!! I brought my car back for fan belt repair several times and it is still not working right. This shop is a rip off, stay AWAY. It is not worth even ONE STAR.

My dad and I have been bringing our vehicles here for a few years now. My go to folks for any of our repair needs. They are always on time and make sure I understand what is being repaired and recommend preventative measures. HONEST! Brendon C. Orinda, CA

You took my car to get its smog check after my oil change. And my car was sparkly clean inside & out!

Brought my Audi r8 to check for steering vibration the car was diagnosed and Found out it was a rim bend the staff did a great job with the diagnostics. However I never got a call to let me know to return to the shop so the car was just idle in the parking lot. Bruce was helpful he informed that he was going to email me with rims and tires options for the car however I never received the email with the info. Thank you

My rear bearing was completely screwed and they fixed it in a short amount of time but what was even better was the price and most importantly the customer service. They were extremely nice and made sure I understood the problem. They fixed my car in no time. I will definitely come back to them! Although hopefully I don't have to!

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.
