This is the only shop I trust completely. And I never feel utterly broke afterwards. Usually people check their invoice to make sure they're not overcharged for something. Here, I check my invoice to make sure they didn't undercharge me. I actually thought he forgot to charge me for some things. But no, it was correct. They are extremely affordable and honest here. Customers aren't treated like vulnerable suckers and dollar signs. Quite the opposite. I'm sure they see so many people go to other places to be told their car needs excessive and unnecessary repairs. Mike is awesome and explained everything to me. Cars are definitely not my area of expertise. And Mr. Truong has been a lifesaver countless times over the years. He's also hilarious. I'm very grateful for people like you both. read more

Smog Check. Manager was very knowledgeable and Helpful. Vehicle was in and out in less than an hour. Everything went so well I plan to use this shop for all future mechanical requirements. read more

Trong is the best! His mechanics are ace mechanics and trustworthy. Their prices are competitive and they stand behind their work. Trong is a great troubleshooter when it comes to pricing out a repair. I could not recommend him more highly! read more

Yesterday, Accu Auto Service earned my trust as a new customer. Mike's pleasant personality was welcoming (fun-fact, he's a polyglot!). Miguel and another nice mechanic were very attentive and professional. My oil change was done within 10 minutes. There were no upsells, nor any questionable tinkering. They performed as a good team. Thank you so much guys! I have not met Trong, the owner, but would like to thank him one day personally...it is not easy finding an honest and well run shop. I'm elated that I no longer have to change my own oil for fear of what harm may occur. Please support Accu Auto Service, they will take good care of you and your car's maintenance needs! read more

5 Stars for a reason! Mr. Do is the best. Reliable, honest, and quick! Have been coming to his place for over 10 years and he's never let me down. read more

I only trust my car to Troung! My family & I have been bringing our cars to him for over 20 years! They are always honest and never lie about what work needs to be done! They are the best auto service !! read more

Had an issue starting my car and brought it into Accu Auto for the first time, since we needed to find a mechanic closer to us. This place is honest, couldn't find anything wrong with the starter, got the car working again and said we didn't need to fix anything. It's been working great since then. A few days later I brought in our minivan for an oil change and to fix the radiator. Prices were reasonable and it was done quickly. Would recommend. read more

Accu Auto Service still my number 1 recommended auto mechanic. He's one honest so humble mechanic I ever met. Bring your car for any problem he will look and check your car for the problem, he will give you advice before he start working on your car. I recommended Troung to my friends and family and all I hear is good comment and they are all happy. Highly recommended to all. AAAAA++++++++++ read more

The owner of ACCU AUTO is always fair and not over priced, I would highly recommend this Auto Service. He services all my family's cars (4)

I initially took my car here for a routine service several months ago. Pricing is very reasonable and by that I mean much cheaper than other shops and dealers. That in itself should have been enough reason to write a great review. However, today I'm writing in regards to my wife's minivan. It was having issues with the brakes (brake booster to be specific) and Truong assessed the situation and gave me very reasonable and sound advice of what to do and how to approach since I was only one month outside of my new car warranty and still under the 36K mileage. He didn't even charge me for the inspection/assessment which I later learned Toyota would have charged me $90 for. Talk about honest, dependable and reliable service where they don't nickel and dime you. I have already referred several friends here prior to today but thought I'd write this for the Yelp community to know how great Truoung and his ACCU Team are! read more

Great service from Truong. We bring all our cars here and the service is timely, a good value, and well done! It is such a blessing to be able to trust our mechanic! read more

I have been bringing all of my cars to them for a long time and have always gotten great service at a fair price they do not try to sell you anything extra i have sent family members as well read more

Another Orange County's hard to find trust worthy auto service/mechanic shop in Lake Forest. Troung will not do anything more than what your car needs and will charge you less than what you would normally pay others. Great place to bring your own parts for older M Benz for wiper blades install and any exterior light assembly replacements. You wont find a cheaper place for oil service where you can bring your own Mobil1, OEM oil and cabin air filters. Leave your vehicle with Troung and don't stress about it. You're in good hands. read more

Truong has always been very honest and good to us. We have been using him over 15 years and have no hesitation to trust him. Honest mechanic at a good price. read more

Our car was making a rattling sound and with my husband deployed I didn't know if we had our catalytic converter stolen (since that's happening a lot) or what. It's his commuter so it's been just sitting here since he left . This shop was recommended to me via a FB group. I called, he said to bring it in the next morning. He checked it out and said it was just a loose heat shield and he fixed it for free. I was in and out in about 20 min. He was so kind and it was generous to not even charge me for his time. Will definitely go back if the car has anymore issues. read more

The engine in my 2011 Avalanche gave out and Accu replaced it with a GM remanufactured engine. He did a fantastic Job and his pricing was right in line with all that I researched. Tran was great to deal with and completed the job before the expected date. Others in my family have used him and I wouldn't hesitate to go back there if the shop was closer. Thanks Tran! read more

100% would recommend Accu Auto Service. I had a long list of maintenance items needed done on my car. Truong was able to give a quote over the phone right away. I dropped off my car the night before and he had it ready by 5pm the next day. Everything on my list was completed perfectly and he even fixed a mysterious squeak that I didn't mention to him. He charged me $1,000 less then what the dealership had quoted. Great price and work. Although it's a long drive to Accu for me, I will definitely keep coming back. read more

I'm torn between a two and a three star review, not because the service was bad (pretty quick oil change, friendly workers) but because there were no masks being worn by any employees except for //sometimes// outdoors, which isn't even where they're recommended to be worn as much. They only have an acrylic screen between customers and the non masked employee inside the office, which does nothing to protect against aerosols that could contain the virus. I felt extremely unsafe even setting foot in this establishment. Luckily much of this place is outdoors, so it could have been worse, but I absolutely did not appreciate the lack of concern for the safety and health of their customers and employees. read more

I was referred to Accu Auto Service by friends and family and I finally had the opportunity today to benefit from their outstanding service. I had an issue with my brake lights and with acceleration while I was driving. Their expert service team diagnosed the problem quickly and had ordered the part and replaced it within a few hours. The most impressive part was that they were very honest that they felt replacing that one part would fix both issues. I appreciated that they were upfront and honest and didn't try to take advantage of me. I was out of there for less than $90! I highly recommend Accu Auto Service. read more

Troung is the best! Extremely honest and thorough. Accu has been working on our cars for more than 25 years and has never steered us wrong. Fair prices too. read more

Accu Auto Service is consistently providing phenomenal service at reasonable & low prices to satisfy your budget. My family, friends & I have been going to this establishment for almost 20 years to get our cars repaired and the service keeps getting better & better. Truong and his team of mechanics will give you an honest straight forward answer to all automotive problems you encounter. No hidden charges like some auto repair shop would give. Updated with latest tools, even the décor of the shop along with a waiting room bolsters a cool comfort zone with internet and LCD TV while waiting for your car to be fixed. No-hassle establishment for over 20 years in service. I would definitely recommend Truong & his efficient mechanics to everyone with automotive issues from simple oil changes to a major mechanical/electrical repair in the South Orange County area. read more

Dr. Truong is the best there is! I'm so glad my neighbor recommended us to Accu Auto Service. He's had multiple opportunities to "increase" my bill, but due to his honesty and integrity, that's never happened. He has my business for the next 100 years. Wish I found his shop 25 years ago. A few years ago, I actually had Rancho Santa Margarita Honda tell me all the brakes in my 2005 Pilot needed to be replaced immediately!!! The service rep there went so far as to tell me that he wouldn't let his mother ride in my car because the brakes were sooooo worn out. I wasn't buying his typical useless car-dealer line of crap. Took the same Honda Pilot to Accu. Truong said only my front brakes needed replacement. The rear brakes were just fine for another 20,000 miles (and they were). The world needs more good honest, respectable and reliable business owners like Truong. Car repair places have such a bad reputation. Truong is the opposite read more

I only went in for an oil change, and I love this place already. Truong is incredibly friendly and the main office is clean and presentable. While it was not busy at the time, my car was already on the blocks getting serviced within five minutes of me sitting down. I also really like how the waiting area has windows and does not feel like a boxed-in prison cell. The kid in me also loves that they have a window into the service area! Something about cars getting lifted into the air gets me excited for some crazy reason. The window into the service area also reveals how clean and orderly the working area is. While it may have no direct effect on me, it conveys that Accu really values organization and cleanliness. That's a great indicator about the caliber of service you will be getting at Accu. It's a crime that I wasn't having my car serviced here before! read more

The best auto Mechanic this side of the Mississippi..honest and fair.. only replaces what needs to be .. doesn't overcharge or brake more then what already was. Me nor my family will ever allow another person to touch our cars because we can trust the job was done right the first time. Very important for a peace of mind. Thank you tron for everything! Your the best! Just did my clutch and e break on 1996 Dodge Ram .. this was 6 months ago.. I now need a water pump and timing chain gasket were coolent was blowing out of.. He fixed it and even went beyond doing another gasket because it was in way for free! He is the best! You won't be disappointed going to him! Really!!! read more

I absolutely love coming here for all of my auto needs. They have serviced three generations of my family and never let us down. The people working here are friendly, knowledgeable, and won't throw surprise repairs on you. As a female sometimes it's difficult to find a car repair shop that you can trust but Accu auto is always my go to! read more

I was referred to Truong and the reviews are on point. Honest man who will only replace what needs replacing. I thought I was going in to get my battery replaced with new cables. Drive from his business with only replacing the battery cables. He could have easily replaced the battery (that's what AAA recommended) and I wouldn't have known any better. Amazing! I will take all my vehicles to ACCU Auto Service. read more

A good measure of whether a mechanic has fair rates is a basic break and rotor replacement. I can no longer support this station repair shop. He was going to charge us $500 for front brakes and rotors. I went up the street and had it done for 300. There was also a miscalculation on another repair that he was wanting to charge $600 for. I had another mechanic determined it was not nearly as bad as we were told and it only cost $100 to repair. May be a bad day by this shop but a very costly one because they lost a long-term customer. read more

My dad has been going here for over ten years for smog checks. Finally, my car needed routine smog checks for the DMV. Took it here and was greeted and treated very nicely. My car was ready in no time. Price was definitely reasonable. They have a pretty decent waiting area, too. I think there was a computer in there last time I came here. It's been a year since I've been, but I decided this place needed a 5 star yelp review. Strongly recommended! I'll be coming back for sure (as is my dad with all 3 of his vehicles). read more

Mr. Truong and Michael, Thank you so much for making my car drive like new again! read more

Honest. Reliable. Integrity. Professional. Friendly. These are the words that come to mind when I think of Accu Auto. Nobody likes to bring their car into the shop, but when I do I know where I'm going. I've been a faithful customer to Accu since 2007 and I highly recommend them to anyone in need of auto service. read more

This is my second time coming here and both times the Mr Troung treated me extremely well. Brought my civic previous for stater problems and he gave me a deal on it. Now the engine light came on and the car started rough. He inspected AND reset the light for free. Honest business. Make this place your first choice before going anywhere else. read more

I go to Accu Auto for all of my car needs. The first time I went here, Troung told me I didn't need the $750+ repair another shop said I needed and just needed new brake pads. That was 3 years ago and I go to accu auto from now on. read more

Wow what a honest company...you will not find a better auto repair shop than Accu Auto...I brought my SUV in to check out a "Check Engine" light and within an hour of tests and checking out my other concerns Truong gave us a run down of the warning light...it was nothing more than a loose gas cap that triggered the problem. What was more shocking was that Truong didn't charge for the diagnostics. I can't count how many times that I was charged for a simple diagnostics at the other auto repair shops. This tells me that Accu Auto Service is the most honest company that I have ever encountered. My choice is Accu Auto Service...hands down! read more

I decided to give this place a try because my roommate got great service there. I am glad I did, because I found out my old shop had been ripping me off. The service was fast, friendly, honest, and inexpensive. I wish I'd known about this place sooner! read more

I was referred by a friend, after buying a 2001 Toyota, that I had been given very expensives repair quotes. Truong did the same work for about 50% of what I had been quoted. The next time in, my oil pressure light was on and he found an inexpensive removal of oil pan and rinsing a filter removed the sludge and saved my engine. Today, after my check engine light came on, I left the car and returned to pick it up and there was not even a charge. Here is a shop that is owned by an HONEST expert mechanic. You can not find better at any price! read more

I've been coming here since I moved to Southern California 12 ago, since my dear dad has always been my mechanic and he's still in Denver, Truong has taken place of my dad as a honest and reliable mechanic. The other fellas are great too!! read more

I've been going to Truong ever since I had my first car, which is now about 20 years. All my family members in the Mission Viejo area has been going to him for many years. He's very honest, fair, and does not try to up sale you. Very straight to the point and gets the job done. read more

I called because I need to get my rotors resurfaced and I was going to bring in just the rotors for them to put on the spindle and resurface. The guy on the phone would not give me a price until I told him my make of car. Once I told him I own a Lexus he quoted me $100. Seriously, you have to be messing with me. I have paid $15 for each rotor at other places but decided to give this shop a chance. NO thank you! read more

Been going here for 15 years. I've never found a mechanic I trust more than Troung. Seriously. I cannot recommend him high enough.

I have been going to Accu auto for at least 20 years. Troung is very skilled and trustworthy. My family goes to him as well. I would definitely recommend anybody and everybody!! read more
