You will always find excellent, honest, and professional service here. Ive 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. Its hard to find another auto shop as trustworthy and reliable as them.

Good honest shop. After the correct part arrived, repairs went fast!ThanksJohn

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.

Harry Sr. And Harry Jr. Are really polite and friendly. They have excellent customer service. They are honest and really inexpensive. Today was my second time taking one of my cars there. Thank you both! :)

I came in with my commuter car that my wife was worried about suspension wise, I was greeted by Harry JR. And Jimmy inspected my vehicle, both men were straight shooters and even told me that there was no real need for any large repair as the car was older and had almost 200K mi on it, and didn’t charge me a thing. The fact they didn’t try to sell me on anything and kept things straight I truly appreciate! I will be coming back here in the future for sure!

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!!

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

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.

The name says it all... I am a certified mechanic, however every now and then I dont have the time to work on family vehicles so I Honest-1 Auto Care do the repairs. They are very fair with the prices and great quality work.

They were closed today I was going to try to give them even though I felt totally disrespected when I visited you last time I had to beg for a business card I tried to give you business now youre close peace to watch man slash speaker man

It was not honest something that could be fix so simple I got charged $49.99 and they told me I did not pass smog. I should get back my money I am disable I dont have that much money. Thank you.

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

Great experience, I recomend their services 100%

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. Im 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😊

The best!

Ive been going to the guys over at Honest-1 Auto Care for a couple of years now and I wont 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?!

I dont know them well enough to say but if its busy all the time it speaks for itself

Not following Covid-19 guidelines. No mask wearing by any service members/staff.

Really caring and honest. They go the extra mile to solve issues about your car.

I would be lost (and quite literally) and stranded without this place. Harry & Harry Jr are great -- all of the mechanics here genuinely care about their customers and the work they do. They take their time to explain whats going on and in a way that makes sense to people like me; cars & parts to me are complete rocket science. I never want to go anywhere else!

Honest One, Harry Sr., Harry Jr. & Jimmy is completely trustworthy. Countless of times they have saved us money with our family vehicles. They completely understand urgency. Completely professional and they go the extra mile to check your vehicle is safe again. I highly recommend their services. They get the job done!

Unfriendly and not helpful. I called early when the shop opened to get an estimate on replacing a rear headlight assembly. Henry ( I believe, not sure.) Wasnt able to call in the part price probably bc he was too busy. Perfectly understandable. I left my number. I came directly to the shop 3 hours later bc I was in the area. Same guys response was you the guy that called earlier? I dont have that estimate. He seemed irritated I came in person and didnt offer a time frame. I guess they dont need my business. Thats the last time I take my car there. Usually theyre friendly and have good prices.

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 havent had time and leave the car we will look at it in 1 hour. It means they even didnt 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 hasnt looked at the car? The inspection takes only 10 minutes. He didnt answer my questions and very rude gave me the key.

This is a family owned business where both father and son really go the extra mile to take great care of customers. Love this place, even though my work has caused me to move to San Diego, I still come back here to have my car worked on...yes, they are THAT good.

Very satisfied, they are really honest, and i highly recommend Honest-1 Auto

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 couldnt 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.

Very respectful staff, actually went out of their way to point out that my splash guard was broken and down and brought me back to show me how he could try to fix it himself. I offered to pay him extra and he insisted he couldn’t charge me and asked for a very reasonable price for an oil change. Also went out of his way to explain my oil filter and how it works. Had a great visit would absolutely come here again.

Honest is the key word. If you dont have a mechanic you trust, you will after going here.

The most dishonest place you can find!Go to this auto care if you have extra money and dont 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 couldnt 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 couldnt 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

I trust them with all my auto needs. The place is clean, inviting and comfortable while youre waiting for your car to be serviced. They provide free shuttle service. They have a small childrens play area.

Had them perform an engine and transmission swap done on my Honda Civic. Couldnt be happier. Staff is polite and knowledgeable. Will definitely be returning for any future repairs.

My experience at Honest-1 Auto Care was 1st Rate all the way, they fixed a problem for me i thought was going to be a lot of money but it wasnt at all. fixed it for nothing. Had them check out belts, Brakes a wiper,.gave me an oil change and Fixed a turn signal lite for free. Everything was fine They charged me just for the oil change, Originally I was there not long b4 closeing so i left the car. took me home, called in morning.picked me up, they did a Great job with honesty, and More, Thanks to All there, Charles Kirk

These guys are outstanding! They provide exceptional service. Their name speaks for itself. By far the best team of mechanics I have ever experienced. Will never go anywhere else.

Very good place to have your car service and repairs done people are very friendly and very competitively priced

This review comes from Dave Gimbi - Diamond Bar, CAHarry and Jr. are the best around. And hopefully Honest -1 corporation realizes this. Very fair and open to rationalize in proper order what your car needs. My 2006 Honda has 180,000 and my 2008 Chrysler has 111,000 miles. He also now works on my fiancées car with 150,000 miles who brings her car from Long Beach. So pretty obvious, I think the world of this father / son team.

I like Honest-1 alot. Lucky to have them a decent distance!

Ive been coming here since they opened. Very honest team here. Harry (senior) and his son Junior, are good at what they do, and I service all of my vehicles here.

Good people, cool stop,Made me feel comfortable & confident ; thank guys!See Harry!

Honest work, great and fast service, ask for Joseph or Alex..

When replacing an engine, you would think they would replace all the seals as well...I had to go back and they charged me to pull the engine to replace a seal they didnt replace. Not recommended due to lack of common sense. Go with a AAA approved auto repair for the peace of mind.

Always great service and my car runs great! Thank you Junior!

Very neat and clean place. I was very much impressed with their professionalism in dealing with repairs, quotation and going extra miles to complete the work on time.

Great place to fix your car . Very nice people !

Amazing. Just went in for a check engine light. Expected the song and dance with the big problem that needed to be fixed and a big price tag to go with it. Instead I got a straight explanation for a problem that was not urgent. No charge! These guys really are Honest!

They always take very good care of me here. Getting my car fixed for some reason or another is stressful because it messes up my entire day but when I bring my car into Honest 1 Auto, the stress just melts away. I wouldnt trust my car with anyone else. Thank you Harry and Harry for always taking good care of me!

Such kind, caring, and honest people. Will be taking my car back there!

Ive always taken my car to the dealership to get fixed. Months ago, I moved to the Phillips Ranch area. I needed to get my battery checked, and Harry was accommodating. Rather than charge me for a new battery (which he could have quickly done, and I wouldnt have been any wiser), he found out that my battery was under warranty and called around to find a dealership who could take my car that day. I knew then, I could trust him with my vehicle. Fast forward to August 18, 2018; I brought my car back to Harry after being told by a representative at Pep Boys that I needed new breaks after visually inspecting the breaks on my car because I was at a .4 and they require a .5 to give a Passing grade for Lyft drivers. I promptly said no thanks and brought my car to Harry. Harry took the time to thoroughly check my breaks (which do not need replacing right now) and inspected my car for Lyft. If youre looking for a trustworthy place to have your vehicle serviced, look no further, the service here lives up to the name of the business!

My girl got her oil change here and when the next maintenance was due on her car I decided to change her oil these people tightened the oil plug to tight to a point the bolt was stripped, I couldnt get it off with a tool took over an hour to finally get it off from how tight they tightened it, when i saw the oil that came out of the motor i was even more pissed they put cheap oil in her car. Warning you now never go to honest auto care they are not honest people then I went to change out the oil filter and they never changed it out it was the same oil filter from last time they charged my girl all this money and the entire oil change was cheap and half asset worse place to take your vehicle. For now on Im fixing her car

Wonderful experience here with both Junior and Senior. I will return.

Have taken a couple of my cars here several times. Pricing is always reasonable and the quality of work is good and they stand behind it with a good warranty and roadside service, if needed (which I havent)

Closes at six, came at 3 for an emergency oil change after being passed around by other idiots not wanting to help and suprise suprise, closed.

The best honest mechanics around, not out to rip you off like some places are!

They take good care of my car here. Harry is the owner let him know Kevin sent you there! Excellent service, clean place, wifi to work while you wait, coffee/water, and affordable pricing! I drive Uber and Lyft so my car needs to be checked often and running smooth oil changes, breaks, ac, tire rotation etc.

Always honest! Always fair!

Great, trustworthy, reliable and reasonably priced service.The professionalism of a chain with the charm of a family owned and operated franchise. I have been coming here for years.

Great customers service.

Harry Sr and Jr are 2 people anyone can trust for their cars

Great service, honest and caring

Top notch service - Top notch Mechanics!!!

Had purchased a discount coupon that they didnt want to honor. They treated me like a wet food stamp.

Hood place for car problem

Love it
