Cautionary Review - Please Read Before Visiting…read more I had a concerning experience with Millennium Auto Care in Brentwood, and I feel it's important to share for the benefit of others in the community. In September 2025, I was steered to this shop by a AAA-contracted tow truck driver who strongly recommended it over a AAA-approved facility. I later realized this may have been a referral with personal incentives -- a red flag in any service industry. The shop diagnosed my car and quoted nearly $1,200 in repairs, demanded cash only, and refused to take a credit card for the diagnostic fee. That alone raises serious concerns about transparency and accountability. This wasn't my first bad experience with Millennium. Back in 2021, the same technician exposed wiring and suggested vague electrical issues that felt like a setup for unnecessary diagnostics. I recently discovered that Millennium Auto Care was formally accused by the California Bureau of Automotive Repair (BAR) in 2018 for violations including: Charging for parts not replaced Performing unauthorized repairs Failing to return replaced parts (Source: BAR Accusation Document) This is public record and speaks to a pattern of behavior that matches what I experienced. I've since taken my car to a AAA-approved shop that was transparent, professional, and backed by warranty. I'm sharing this to help others avoid being misled. Always verify shop credentials, check BAR licensing, and don't let tow drivers decide where your car goes -- especially if the shop isn't AAA-approved. Would have given them no star rating but minimum is 1 star to even get a review posted.

I called a couple local places, and One Stop quoted me the best price, and charged by the pound on freon when other places in town charged a flat rate of TRIPLE what I paid at one stop. We arrived, and talked to Chad and I went in to do Paperwork as Chad harmlessly flirted with my fiance (I understand Chad Shes GORGEOUS) We headed next door to an Air Conditioned Mexican food place, came back and the car was done. Chad told me, that JUST IN CASE there was a leak, he put some dye in the system! Went to go pay and I dont know how it came up, but the nice lady inside alluded to having some native artifacts.... I checked them out but didnt get any... All in all... Great experience! Glad we found them! Would recommend! Also.... a HUGE THANK YOU!!!!!!

After explaining my situation with what my vehicle was doing they seemed very happy to help me. They squeezed me in at the very end of the day, diagnosed my car and I authorized the work and shortly was on the road to my family.  The mechanic was very knowledgeable and explained in full detail so that I understood. Ashley, the office administrator was my 1st contact when I called and she made me feel important and was eager to help. The service from my 1st call to the office and then mechanic of my car was 110% Above and beyond my expectations.  I recommend them over any other shop. Call them and you will see, you will end up making them your One Stop Only Shop Go To Mechanic knowing you are receiving the most excellent top knotch service and skills from a highly experienced mechanic.
