Diamond Bar Auto Care

I usually get great service at a fair price when I bring my vehicles here for service. I brought my car in to have my water pump replaced, it was leaking coolant. Instead of replacing my water pump, they replaced the radiator, also the price for the radiator replacement was at the high end of cost for this service. When I got home I had a coolant leak coming from the water pump, problem not fixed.

Honest Mechanic has very excellent customer service and is very reliable

I dropped of my 2011 Hyundai Elantra because my A/C was blowing hot air. Harry and the rest of the guys were awesome and now my car's A/C is working perfect again. I will definitely be back as I've been coming here for years. Top notch service!!

You will always find excellent, honest, and professional service here. I've used Honest 1 Auto for about 4 years now and they guarantee their work. Among the many various services over those years, I have had oil changes, brake fluid exchange, transmission fluid exchange, starter replacement, strut replacement, etc. I trust their work and will continue to use them even though I have moved farther away now, I will drive back to this shop. It's hard to find another auto shop as trustworthy and reliable as them.

Check engine light was flashing and our over 250,000 mile 2003 GMC Envoy was shaking and running rough. Thinking we were going to need a replacement car soon we still got it to Honest 1. Got a call back the same day telling us what was needed. Our GMC Envoy runs like new again. We want to thank you again for your fast and amazing work. Also you always remember us and ask about our other cars. Your attention to detail is refreshing along with your matching Honest 1 name.

Honest One is Awesome! They are always so helpful, friendly and Honest. Harry Jr. Is the Best!
