“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”
“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.”
“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!”
“Had the pleasure of getting my car serviced here Tuesday 5/19. Gus and was extremely helpful and professional. Will make this my go to spot for vehicle maintenance.”
“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.”
