“Arrived for appointment to have oil change and tire rotation for 2018 Subaru Outback. Also asked for brake inspection. Cot was half that I would have paid a dealer. Exceptional; service without the 2 to 3 hour wait I've had at dealers for the same service. They said I had at least 6 months on the brakes so they weren't trying to push a brake job. Finally, Under the federal Magnuson-Moss Warranty Act, a manufacturer cannot void your warranty just because you had routine service done at an independent shop.”
“Had an issue, Jacob took care of it...AGAIN...I had a broken custom rim and Jacob had it repaired in 24 hours... excellent service here. ALWAYS EXCELLENT SERVICE”

“I brought my B8.5 S5 in for a Berryman piston soak, 85K scheduled maintenance, and while I was at it, had these fellas install a new brake kit and brake lines. They were thorough, expeditious and very reasonable in price. Joey made sure my aging Audi was tip top and they even fixed something that I didn't even mention! They definitely have my trust.”
“Oliver was really amazing. Could’ve upsold me in a few different things that were needed for my mom’s car but he was honest and extremely knowledgeable. I won’t be taking my car anywhere else as long as he is still working”
“Thank you Mr. Hami for taking time to talk to us not only about 2008 Lexus RX-350 but also to try to understand our situation.
Having been serving in the mission field for the past 9 years in Southeast Asia, we are only driving the car a few months a year. Understanding our circumstances, Mr. Hami took a quick inspection and gave us a few recommended repairs. But he didn’t push us to decide, instead he worked with us in selecting what was the more urgent needed repairs and put on hold those repairs which can wait a little bit longer so that we can accumulate more budget to take care of the rest of repairs.
For that, we want to say: “thank you Mr. Hami.””
“A Toyota dealer recommended a comprehensive wheel alignment, transmission pan and gasket replacement, battery replacement with terminal cleaning, and the A/C evaporator cleaning, with a total estimated cost of around $2,000.
The dealer worked on my transmission fluid system for the leak in the last two years in a row, which cost me around $1,400, and replaced the battery two years ago.
This time, I took it to Diamond Bar Auto Service. A mechanic checked the conditions of my 2014 Toyota Corolla and cleaned the battery terminal corrosion using cola. That was it, and there was no charge.
I don’t know whether this fix will be fine. I am sure, however, that if something goes wrong with my Toyota, I will take it to this place.”

“Went to 3 other mechanics to fixe my car door locks on my Toyota Camry. Steve was the quickest and most reasonable for prices. Glad I went with him. He guaranteed his work.”
“Honest, Reliable, and Truly Caring Service!
We had a small leak in one of the tires on our Cybertruck and stopped by several other places first — all of them told us we needed to replace all four tires, even though they weren’t worn out. Thankfully, we found Honest-1 Auto Care in Diamond Bar!
True to their name, the team at Honest-1 quickly identified the issue and fixed the leak without pushing unnecessary services or upsells. They were professional, straightforward, and genuinely had our best interest in mind. It’s rare to find an auto shop these days that actually lives up to the word “honest,” but this place absolutely does.
Highly recommend them for anyone looking for trustworthy and knowledgeable service. We’ll definitely be back if we need anything in the future!”
“Guys were great I was doing an emergency plumbing repair next door and get in my truck to go get parts and I realized my tire was flat! Everywhere else was over a 2 hour wait but they were able to get me in right away for a reasonable price and get be back on the road to finish my job!”
“2015 Kia Forte5. Arrived 9:00. Engine check light was on and engine was missing on one cylinder. Diagnosed at 9:15 as a failed coil on one cylinder. It was fixed and I left at 10:00. That was 4 months ago. It still works. Not my first visit here and won't be my last.”
“Very convenient place. Near target. You can walk in. I arrived at 8:00. Got the oil changed around 9:40 without an appointment. I would say waiting time it's not too bad. He would not charge You anything which is not necessary. The price is fair Compared to my previous shop. The owner is very nice and professional. He explained everything very clearly. The staffs are very nice. I would come back!”
“Great service!
Great gentleman!
Nick was so understanding and even stayed open longer to help me out. I’ve been a returning customer and I will continue to come back.”
“Had that classic Tesla Model 3 squeaking control arm issue and dreaded what Tesla was going to charge to fix it. Brought it to Auto Squad DB instead—they were super professional, fixed it fast, and charged way less than Tesla. Save yourself the money and headache and just bring your car here.”
