I have used Munoz auto for years and they have always done incredibly fine work. They have always been fair in pricing and have always guaranteed their work. Mostly, I have appreciated that they have rescued me several times when I had something go wrong on the road. They have come right out and fixed it there or repaired it well enough to get it back to the shop where they could do a more thorough job. Five Stars.
The owner of this shop is a fraud. I recently sent my girlfriend to have a simple retention pulley looked at, and nothing else. When she returned, in tears might I add, she told me that they charged her $10 to tighten a belt (that was already tight and verified by a prior mechanic shop) as well as drained the freeon from the A/C system while saying it was already empty. Lucky for us, we were at a shop no more than 3 months prior and the A/C was charged then as well as new belts being put on. When I confronted them directly about this, they opted for the the "well, you can just take us to court. We don't care," mentality. Well, we have, and they lost. All told, it's cost them a great deal of money. The point is, unless you break down in front of their shop, I would recommend you find another place to get your car checked as Munoz Auto Service is now officially a shady company that has been proven to not provide the services they claim.
