Engine repair service near Mountain House, 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.

I've been going to Autowise for years. The people who work there are friendly and professional. Right now my family owns and maintains 5 cars. Autowise services all of them, and I have never been stuck by the side of the road in any of them because they do such good work. That is very important to me, especially when my children are behind the wheel. As far as price goes...cars are not cheap to maintain! I would recommend that you shop around. You might find a better price, but remember the old saying...You get what you pay for!

Terry is very helpful & definitely has the best prices in town. I will be taking my business there & will definitely refer anyone I know in need of auto services there as well.

The most honest auto shop in Modesto. I highly recommend this shop to EVERYONE!!! They got my car up and running within 24 hours.

Do use this shop!!! cost me over 4,000 dollars,and when I got my car back, I had them pull the motor and put it back in. the motor never had any power for a new motor.I pulled it out took it to a machine shop in colfax, ca BOUTRY'S ENGINES, he was supposed to find the problem and fix it. Not only did he not figure out the problem!! After paying him 1,800 dollars!! I put the motor back in the car and the rear main LEAKED so bad i could not drive it! I found a competant machine shop in petaluma,ca NORMS MACHINE SHOP they do race engines! norm jr inspected the motor and informed me the pistons were down below the deck 110"!!!! this motor has stock 906 heads that have 89cc combustion chambers, the compression height was too short!!!rettig bros mistake!!!! and a very costly one,in horsepower and money,and my labor taking the motor out two more times!!! and Dave rettig will not give back a dime!!!
