I am so grateful for this place. I don't know much about cars, but Aaron made the whole experience entirely easy and stress-free for me. He has wonderful manners, and his clear communication, explanations and attentiveness made me feel so looked after. I felt like he went above and beyond by fixing things I didn't even ask for, all for what I believe is more than a fair price. His kindness and professionalism really stood out, and my car seems to be running perfectly now. Thank you, Aaron and DNZ. read more

I previously left a five-star review because I had a good experience here. At the time, EU was honest enough to tell me I didn't need a tire rotation, which saved me money as a student. Because of that, I came back for multiple oil changes. Unfortunately, my most recent visit was completely different. I was charged a high price for what should have been a simple oil change and cabin/air filter replacement, and I ended up waiting about two hours for the work to be completed. After talking it through with someone more familiar with car maintenance, it became clear that I was likely overcharged for a job that should have been quicker and more reasonably priced. What made the experience worse was the interaction before my appointment. When I asked for clarification about being told I may need "air," EU laughed at me for asking. I'm neurodivergent and sometimes take things more literally, so I was just trying to confirm whether I was being charged for something that is often free. Instead of explaining, I felt mocked for asking a simple question. Because of this experience, I no longer feel comfortable or confident returning here. I'm sharing this as a caution for other customers--especially women and neurodivergent people--who may not be as familiar with car maintenance and rely on mechanics to be honest, respectful, and transparent. read more

$1350 Repair Failed Immediately - Check Engine & Overheating Review: In May 2025,I paid over $1,350 at DHZ Automotive for a major repair that included a new timing belt, water pump, and thermostat (see invoice). The result was catastrophic. Immediately after driving away, the check engine light came on and the van began overheating again, reaching dangerous levels (see photos of the dashboard gauges). I returned immediately. Their own scanner pulled codes P1130 and P1135 (see photo), which are related to the air-fuel sensor and heater circuit--issues that were not present before their work. Despite this evidence, the service advisor and owner dismissed it as a "coincidence" and asked for more money to fix the problems they created. The disorganization was shocking. An employee actually had to call me and ask me to text them my own invoice because they had no record of what work had just been done on my car. How can you trust a shop to warranty their work if they don't even keep their own records? They refused to honor their own 1-year warranty. I've had to use my own scanner to monitor the car myself (see photo). The attached invoice proves the work they did. The attached photos prove they failed. This shop cost me over $1300 and left my van in a more dangerous state than when I brought it in. Avoid this place at all costs. read more

Horrible!!!!! i was recommended this place to get my car fixed. i should've realized this place was bad when i overheard the mechanics looking at You tube videos to make a repair to a car. i proceeded to let them repair my car only to have to take it to another mechanic and spend another $500. this place is not legit!!! read more

Since moving to Costa Mesa 5 years ago, I've only come to DNZ and nowhere else for my car repairs/maintenance. The customer service here is truly unlike anywhere else and you really feel like you are cared for here.

SCAMMER. Beware!! bought a used BMW from the owner Engin for my teenage daughter. After a week driving it, the DRIVE TERRAIN light came on, which stranded her at night in Los Angeles. We called him and he told us to bring it in. She drove it on the 405 going 60 mph with the lights blinking and now check engine light on too. Engin told us it was nothing, just a sensor. We took it to another shop who told us there's $5,000 worth of work needed and he wouldnt recommend fixing it at all. After avoiding texts and phone calls from us, we finally brought it back in. He told us too much time had passed and we drove it before buying it (yes around the block two times is a solid gauge). If he'd do this to an acquaintance, he will do anything to you or your car. Avoid this guy- this place at all costs! You will get scammed! read more

Came here based on the Yelp reviews looking to get my brake pads replaced on my Subaru. The guy (manager or owner I think) inspected it and gave me a good quote of $380 to replace. I was on the fence as I didn't really want to put any more money into a car I was going to be giving away, but my wife convinced me to, so I went back about two weeks later to get them replaced. This is where it went from what seemed like a totally legit place, to a totally dodgy place. A new (different) employee all of a sudden decided that it needed new rotors, etc as well -- even though it had literally NOT been driven AT ALL since they gave me the original quote. Instead, the guy just kept arguing with me as if I was making it up. I told him to look up the quote in the system and he just kept insisting I had to spend more money. So, either the first guy was wrong in his evaluation and quote, OR the second guy was just trying to milk more money because literally NOTHING had changed in the interim as the car had not been driven. Felt like the classic bait and switch that gives a lot of auto-repair shops a bad name. I guess you can add this one to the list of shady businesses that don't care about their reputation as long as they can get over on you. No thanks. read more

They replaced my headlight and flushed my AC system. Extremely happy with their work. Communication was excellent. Coming back for an AC pump replacement next week. Looking forward to keeping these guys as my regular mechanic. read more

Brought my car here for a diagnostic to address An issue and I will say I have never ever felt like I have dealt with a more honest person or business in my life. Most places get ya in and then sell ya a boat full of things ya don't need. This place gave me a straight answer and not once did they try to sell me something I didn't need. I will be back here for all my auto needs. Do not skip this place if you need a repair. read more

I was very happy to see such a quick response . The other estimates were delayed and had more questions than answers. I will contact them in the future for sure thank you I appreciate it . As a contractor I need to have someone I can depend on quickly and efficiently. read more

I've been here a couple times and let me just say this is the first mechanic I've ever been to where I felt cared for, safe, and priced more than fairly if not generously. The whole team is great, their attitude is positive and they are so kind, they are fast and have superb communication (this coming from a comms major!). My car has always come out in great condition and I've never had any issues. This is the ONLY auto shop I trust! I'll be moving soon but I will drive the 2 hours it takes to get here to get my car serviced in the future, they've earned my money and loyalty! I will keep recommending them! Btw I never leave Yelp reviews, so you know this is legit! read more

I found DNZ while searching for a used car. I didn't know DNZ from any other used car dealership, but it turns out that they have a great selection of nice, hand-picked vehicles. Great pride is taken in the vehicle preparation for show and sale. They seem to specialize in BMWs, but had a broad collection of customer vehicles being serviced. I felt valued before, during, and after our deal was struck for a BEAUTIFUL, relatively low-mileage BMW Z4. Not at all like some fly-by-night outfits that just want your money, then hope they never see you again. Ownership stands-by their products and service! I plan on using DNZ for my vehicle's service, as they really know their stuff! read more

The girl at the front desk was great . The service people were nice . Came in at 8:30 to ask for an oil change on my M BMW . Was told at other places it is hard to get filter. They said no problem. Came back and dropped the car at 1:00 . They said it would be ready at 2:30. Then they said 4:30. I show up at 3:30 they are working. on it . Not sure if I'm actually getting the real oil change . $ 166. Not sure it's worth dealing with this small owned business. That's why I wanted them to be good . Next time I'm going to dealership. I know they are gonna do the same BS . I just wish local private own business would do a good job Just so you know nobody asked to change my review. I was just frustrated. I will be going back to for my car service. Mechanics were good front desk girl was awesome. Once again they didn't ask me to change my review, I just change my mind read more

Great shop, great communication and services. I didn't feel taken advantage of or any kind of nonsense. I brought my 2012 Rubicon in for routine service and they found a couple little things that could be fixed preventively and it wasn't an upsell - it was a great that these items were brought to my attention. If you're looking for new shop DNZ has been good to me...Hope that helps you make a choice where to get your service. Thanks DNZ. read more

I can start by saying- we wouldn't take our cars anywhere else for car repair. Not only is the quality of their work top notch, the prices are reasonable. Above all these people are honest and super nice human beings! We feel so fortunate to have found them and highly recommend them to others- if you need car repair give them a call!!! They have gone above and beyond for us- It all started with a phone call! read more

Endorsements from me do not come easily. DNZ has not only earned my trust but exceeded my expectations on all levels. After receiving an exorbitant estimate from the dealer, I reached out to Yelp and made a connection with a few of the highest rated auto shops in my area. Among the shops and mechanics that I contacted, DNZ stood out and ultimately became my top choice, based on the level of detail and scope of the questions/answers discussed concerning the issues. The communication was excellent and it was apparent DNZ was interested in resolving and understanding all of the issues so that an accurate estimate could be generated. The estimate DNZ provided was detailed and all parts were the same or comparable to the parts on the dealer's estimate. DNZ's estimate for parts, labor and the timeframe for completion was significantly less than the estimate provided by the dealer. The quality of service is exceptional; the customer service is outstanding; the communication is excellent and the prices are extremely reasonable. They operate with complete transparency. Importantly, they do not recommend service that is not needed. The owner and his team are true professionals and they take pride in offering unsurpassed quality, value and service. They have literally saved me thousands of dollars. read more

Very welcoming, professional. I really don't know what to say, after hours of work in the diagnosis and since my car was beyond repair, he did not accept any money. A courtesy beyond imagination, he said since it was a bad news and he wished to come with a good news, he didn't accept any money for the exhausting work they have done. Much respect! read more

First of all thanks to engin, I recently purchased a e64 M6 wanted it to get checked for codes and problems let me start with the place, it has good parking spot and waiting room, always call for appointment. Oil change for my e64 M6 is very affordable than the ones at LA and the freaking bmw dealership. If you want you're bmw serviced specially M cars , he's the guy to go too, he has extensive knowledge especially with the s85 engine, he is very detailed when accessing problems, he will let you know which needs to be done first. Lastly the price is really affordable call him and get a quote. Onc again Thank you Engin! Found a mechanic I can trust and wouldn't rip you off. read more

DNZ Automotive - The establishment - Auto Repair Near Me - Costa Mesa, California

Great service. They are an honest repair shop. I went in there with issues on brakes on my car. I did not know if I had to completely replace my breaks and more repairs on top of that, or if I just needed a minor fix. They told me exactly what I needed. They broke down the costs of each part, labor, and what is recommended. Very transparent and descriptive. At the end, they told me about what other mechanics usually recommend versus what they recommend. I would suggest going here if you are looking for a quick fix and an honest price. This place is great. read more

I have been their customer since 2017, they've been changing my oil every 6 months and doing some light maintenance, Firstly, I like the customer relations, their owner is very friendly and always greets me with a smile. Another reason for five stars is the honesty, they always find ways to save me money, and they never sold me anything that I don't need. I will keep being their loyal costumer. read more

Repaired my AC at a fair price and got it done quickly! Very good service and nice team!

Its the best and reliable mechanic ever. Highly recommended. Engine was very helpful and honest , my BMW is so much better than before and they gave me very good prices read more

This review is for the customer service, however, I did not get my car serviced here as I took it somewhere closer to where I live for convenience. I had what I assumed was a leak in my coolant and I called around closing time so Engin told me to drop my car off at 9am. I left my car in the am and about an hour later Engin himself let me know my diagnostics including the price for labor and parts. When I let him know that I was going to shop around he was very professional and even offered to give me a copy of the estimate for me. If the shop was a little closer to me and a guarantee same day pickup (needed car by eod in this situation) I would have gotten my car serviced here. They seem like a legit, fairly priced mechanic! read more
