Nothing but great things to say about Master Auto Care! I brought my Kia in for an engine replacement. When the dealer was unable to get me back on the road Sandy and her team did. She kept me updated every step of the way, sent me pictures of before and after the installation. Never had I been to a shop that actually cared to keep me in the loop and with such a great warranty. I came here because of all the other great reviews and will be coming back because of the great service!

I am beyond satisfied with the mechanical work I got done here! Oscar and Sandy were amazing though out the whole process. They made it super easy the accommodate my schedule which that was super important to me. I had spent 2 years fighting the warranty company about getting my transmission replaced. Went to several service centers and no one can't figure out what was wrong. Then I brought it here to master auto care and with it a couple of days they diagnosed exactly what was wrong with my transmission! They reported their findings and within a week my claim was approved and 5 days later I had my car back! Amazing! Highly recommend this place! They know what they are doing! Thank Oscar, Sandy and staff! You'll definitely see me again for any future repairs!

My experience with this shop and their staff exceeded my expectations!✨🙌🏽 From the beginning to the end! Sandy aka the Boss Lady, did a wonderful job explaining things regarding my vehicle and making sure I was aware of everything! Their cost was way lower than other auto shops I called as well. They even give me before and after photos of my repairs. So Grateful for them and happy I choose them to fix my ride and get it back on the road! My car was in and out within 24hours. I was stuck in Ontario on the way back home to the high desert and didn’t think I would get my car fixed and back on the road so fast, but they did it!
