As a woman who doesn’t know a lot about cars, I’m always terrified I’m going to get taken advantage of at a mechanic. These guys have always treated me great and have been very open and transparent about the work they do and their prices. They do their best to explain the work they’ve done in a way I can understand. They live up to their name!

The most dishonest place you can find! Go to this auto care if you have extra money and don't care about your car. They easily change the parts instead of fixing a small problem like changing a fuse and charge you hundreds of $$$ for nothing (because they are not experts). I was there for just inspection of my care I lost 4 hours and they couldn't even tell me what is wrong with my car. Finally, I was told, a part of engine needs to be replace for $850. It will take 3-4 days to be fixed! I couldn't leave the car. They charged me $54 just for their wrong diagnosis, I went to other shop, my car was inspected in 10 minutes and fixed in 5 minutes. Just the fuse was replaced. I was charged for $15. Save your time and money, be far from this shop

Avoid this place! The positive feed backs are made by their friends and all are fake! I called last week for AC repair. I was given an appointment for 8 am on Saturday (today). I told them I have very limited time and I was told we will inspect the car as soon as we have the car and will tell you what is wrong and will fix it. I was on my appointment at 7:50am. He said we are busy and leave the car and I will call you about 1 hour. He said they will charge me $19.95 + Tax to just look at the car. Nobody called me after 1 hour, I called them 3 times between 9:00 to 9:15am until somebody picked up and told me we are just pulled your car in and inspecting now, I will call you shortly! Again no call back and I nobody pick up the phone at 10am. I drove to the shop and I found my car is outside the place that I left it at 8 am. when I asked him what happened and why nobody called me back the rude person said, we haven't had time and leave the car we will look at it in 1 hour. It means they even didn't look at the car, they lie to me and never anybody looked at the car. I asked why you have told me 3 times since morning that it will take 1 hour and still nobody hasn't looked at the car? The inspection takes only 10 minutes. He didn't answer my questions and very rude gave me the key.

Very comfortable environment for guests to wait while their auto is being serviced. Super friendly staff, and Honest-1 Auto is the only place I trust to work on my vehicles. All around, great company. Harry will take good care of you!!

WOW ... this is the place to have your car fixed. I have a modified vehicle and two other mechanic locations could not find the problem. Harry and Jimmy, found it, fixed it ... and, kept the price well within reason. Hell of a lot cheaper than the dealer ========================================================= :: UPDATE :: Problem came back ... and this time they kept the car for about 2 years and couldn't fix it. Brought in the car running. Had to pick it up on a flat bed. Harry charged me for new parts he claimed was needed - came to find out; they were not. Took my vehicle back to my original mechanic in San Diego ... fixed it within an hour. $300 out the door. I will NOT be visiting this location again.

Amazing place to service your car. I've been a customer since they first opened. I take all my cars here. They never fail! Sometimes the labor is a little pricey, but it's worth the quality work they do! All my cars run amazing because of them!

I have been getting my car repaired here for some years now. This is my go to shop. Harry and his team have made me feel like family! They are not only TRULY very honest, they are community & citizens oriented, which is very rare. They have committed to being professional, honest, and reliable to the citizens of Diamond Bar, and others, and for this we are fortunate to have them. THANK YOU HONEST-1!

I came to Honest1 automotive repair by a recommendation. I am glad I did, the waiting room is very clean, well ventilated, and smells very nice not like other repair facilities that I have taken my cer to. Today the repair and replacement work that needs to be done cannot be done. I have decided to schedule a later time to come back and fix the items. I also like to say that the restoom is extremely clean and et to smells very nice. Why do I bring this up? A clean restroom says A LOT about the business, and the operations managers diligence to customer satisfaction. I highly highly recommend Honest 1 automotive repair facility here i. Diamond Bar, CA.

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.

For anyone curious about pricing here for AC, it’s $160 for diagnostic and $1590 for MY specific labor. $2,100 for my AC to be fixed. It’s out of my budget but I assume it won’t be for others. I didn’t understand that an Air conditioner general service was an inspection only. I thought I was getting a quote for the labor price to fix my car. I misunderstood what was being done to my car so I’m out $160 my fault. I’m hoping this helps anyone else who might get confused like I did. Posting so no one else makes the same silly mistake.

I've been going to the guys over at Honest-1 Auto Care for a couple of years now and I won't be going anywhere else. After one visit, they remembered me, my car and the service they provided for me. Harry Jr. always does his best to keep the cost down on my repairs by seeing what coupons might apply to the services required. They also include pretty good coupons in the emails they send out to email subscribers. To recap, good guys, great service. What more could you ask?!

Great mechanics! Very professional and knowledgeable. I was so happy my car was repaired on same day and I had major repair work done and they were able to do it all in one day. Harry Sr. Was so pleasant! He explained in detail what was needed for my car. I'm very satisfied. My car runs like new again though it is 18 yrs old. I have recommended Honest 1 to my family and friends. First time visit but will not be the last time. Thank you Harry Sr. and thank you Honest 1 Auto Care😊

Been having our cars repaired here for several years. They remember me and my cars. They are very professional. We have a 2003 GMC Envoy with almost 300K that had some extensive repairs that I got back today and it runs like new.

Took my Honda CRV for a simple oil change around 11am. I was told it might take a few hours since they were a little busy and they would call when they were done. I walked a little ways home and waited. I figured maybe they forgot to call or left a mesage that i missed. I Ubered to the shop about 10 minutes to closing and asked about my vehicle. The guy behind the counter could not find my keys at first and after a searh found them with my paperwork..They had not done my vehicle and were closing. I took my keys and left. I wasted an entire day for a oil change. Would not recommend this auto shop

Honest 1 in Diamond Bar is great. Able to service my car the same day or ready the next day if they’re busy. Harry and the staff are professional and courteous. Prices are cheaper than any dealership and competitive to other auto shops. I use to get my 2008 Accord and 2012 BMW 3 series serviced there. Now I get my 2016 KIA Sedona and 2018 BMW 4 series serviced there and they always do a great job.

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!
