Bosch Automotive Motor Systems - Petaluma (CA)

5 /5 Ryan Kramer: I was a customer several years ago. Ernesto and his crew helped with and engine removal and install on my 73 Charger, as well as a very complicated fuel injection modification. Ernesto went above and beyond for over a year to help get my car, a family heirloom, back on the road! He taught me so much during the build and everyone made me feel more like a friend than a client. They value their clients and are the epitome of the trustworthy mechanic!

5 /5 betsy R: Cannot say enough good stuff about Ernesto and his company. My sons ignition, failed, trapping the key in it, in the on position. My son wanted to try to fix it himself so he can have it back ASAP. Called Bosch automotive they got us in the same day. We had already purchased the parts he put the new part in. Had the car back in about four or five hours at a super reasonable price. Could not thank him and his shop enough will definitely recommend him and use him going forward. Thanks again!!!!

5 /5 Ryan Accurso: Honest shop, they diagnosed emissions codes on my Toyota Camry. They went over the prices that everything would cost. They gave me many options. Very knowledgeable and helpful. I ended up doing the work on my car my on my own to save money and they let me know exactly what to replace.

5 /5 John McInnis: My go to dependable mechanic diagnosed our 2003 Miata check engine light caused by a misfire and said a valve leak might be the problem. He said he could not work on it and suggested two other local shops. I tried each and neither could do the job, one saying the reason is there are few automotive machine shops left that can grind valves or do deep engine work. It took a while to find BOSCH AUTOMOTIVE in Petaluma to take on the job. There was a three week wait and another three weeks in the busy garage to complete the work, but entirely worth it. Ernesto discovered multiple valves burnt and in need of replacement. Our wonderful little ride is back to life in tiptop shape, quieter, smoother than in a long time; the pesky check engine light vanquished.

5 /5 George Low: Brought my 1997 4 Runner here for valve cover gaskets, smog certification and oil change. Rod and Ernesto gave me great service, provided a written estimate, did great work and it was ready as promised. A good experience.
