    Great job on our work truck. The Tech was quick to fix the truck. He was polite and easy to work with.

We stayed because of the quality of service , friendly, knowledge people at the front. All our vehicles are serviced by Reliable. The prices are very competitive, for us it is the knowledge of finding and fixing the first time.

BE AWARE they charge you every time they do a test- including a retest ! (which is an extra $185) turned my car in on a Wednesday night before closing, which I knew they were not going to get to it that night, waited all day the next day, did not hear from them whatsoever, then I called them on Friday to find out what's going on, which I needed to wait for the lady who checked us in to come back, which wasn't until 2 hours before closing, to tell me they couldn't get to my car the previous day because of call outs. (All they were authorized to do was a diagnostic which takes 2-3 minutes). She proceeded to say that they needed to replace the alternator, and since it's late on Friday, they needed to order the part, but closed on the weekend and wouldn't get to it til Monday. They open at 8am and I got the call at 842am to say my car was ready. Less than 3 hours of labor and I was charged almost $600, which included a second diagnostic fee. PLEASE use this as advice to go to another shop, and make sure you're not charged more than 1 diagnostic fee, or $600 in labor for not even 3 hours of labor. We thought because of our first experience here it would be okay bringing another one of our vehicles, but we will now be looking for another shop because of this experience. Highly unsatisfied!

    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.
