Apparently these are…read morenotorious for engine leaks and transmission problems but I was searching to get the latter serviced. After getting a diagnosed from Subaru, the amount to fix the transmission issue was in the thousands! I've searched yelp and called around but couldn't find a mechanic that new Subarus very well. I called Mekatron, and finally, like an oasis in a dessert of mechanics with sub-par Subaru knowledge, Ian and his crew knew all about my car. From the engine issues, to the type of metallurgy my transmission was made from! Not only that, they service all Subaru models from every year. My communication with Ian was superb, and he also laid out all my options at very reasonable prices. Not pushy but honest advice which is what you want from a mechanic. If you're looking for help on your Subaru in the Yelp world, look no further, and contact Ian and his team. You won't regret the phone call.

About a month ago, my check engine light came on, so I stopped by O'Reilly Auto Parts in Walnut…read moreCreek for a quick diagnostic. The codes pointed to an Air Injection (AIR) Pump issue; never a cheap repair on a Mercedes. After calling a few independent Mercedes shops, I was not thrilled about the thousands they wanted to charge. When I called O'Reilly's back to order the part, the guy helping me mentioned Mr. Kim at M&N Auto Service, saying he sends a lot of customers there and they're always happy. That was enough for me to give it a shot. I called M&N, got a quote from Mr. Kim, and I honestly couldn't believe it...about half the price of what the other shops quoted. I dropped my car off yesterday morning, and by the afternoon it was done. Mr. Kim was professional, straightforward, and incredibly efficient. Not only did he fix the AIR pump issue, but as a last‑minute request he also replaced a parking light that had gone out. He even checked my tire pressures without me asking. It's rare to find a mechanic who takes that kind of initiative. What really sealed the deal was the personal interaction. We ended up chatting about Korean food, and he told me exactly what to order at Ohgane for the best LA‑style BBQ meats. We were laughing as I left; just a genuinely good guy who knows his craft. I've already referred two family members to him, and one has already gotten their car back and is just as happy with the service. If you're looking for a good, honest, no‑BS mechanic in the Walnut Creek area; especially someone who can work on European cars, go see Mr. Kim at M&N Auto Service. Shops like this are hard to find, and I'm grateful I found mine

BE WARNED, The owner is dishonest and unaccountable. Not qualified IMO to work on closed system air…read moresuspension systems - F rating on BBB. I drive a Jeep Grand Cherokee. My service air suspension light came on a couple times in early Feb so I immediately looked into getting it fixed. Feb 4th, an inspection at Main St Automotive revealed I had air leaks in my right front and rear shock and strut assembly.  After talking to the dealer (who had parts on backorder) I spoke to Main Street again, further inquiring about their expertise. They assured me that they work on all the premium cars with air lift suspension all the time and were very well qualified to do the work. Andrei O, the owner, and I had a long discussion about the importance of buying factory OEM Mopar Parts although they were more expensive. I had been looking at alternative parts sellers (Mopar branded available for $800-1000) but Andre convinced me these sites would be fraudulent and that they would only use Mopar genuine OEM parts. He advised against buying anything anywhere outside of Mopar direct as they'd be fake. He gave me a long story about how he used to work there and knew the GM personally. He sent me the factory link where the parts were priced at $2281.25. Although the bid of Main Street Automotive was more expensive, I authorized them to do the work. I brought the car in on Feb 5 for the service for which Andrei said he had the parts in stock. At 4pm Feb 5th the front desk girl called to tell me "the car is finished and ready for pick up". I arrived to pick it up at the appointed time and Andrei advised that 1) they had just started reprogramming the computer and 2) it could take up to an hour to complete. After waiting 30 minutes with no visible progress, I had to leave for a family affair. They kept the car another day, and advised that they had to open a case with a master technician to resolve the reprogramming. After working with their "master technician", Feb 6th the front desk called back near end of the day and advised "the car was done and ready for payment and pick up" (again).  I immediately paid $3300 in cash in good faith. The car immediately failed while driving off the property. Ultimately the vehicle was taken to the dealer by Main St. to correct the problem, but the diagnostic given to the dealer was incomplete, testing only the top 2 ride heights of which there are 5. The car still did not work correctly in aerodynamic or exit/entry mode. Andrei advised they did not initially have the proper high speed cable required to complete the job. Main St, I learned, can also not complete this job without nitrogen from the  dealer. Main Street Auto then advised I should get all further work completed at the dealer. Their OWN STAFF advised the car was unsafe to drive in its current condition. THEY COULD NOT COMPLETE THE JOB that I paid for. When the dealership received the car again, the master technician (38 years) at the dealer advised that the computer had been reprogrammed incorrectly with the rear suspension ride height improperly set so the rear was always elevated. They asked me "why did Main Street Auto attempt to reprogram it at all, the replacement of shocks/struts and air suspension requires no reprogramming"? I called to discuss this with Main St. after it was shared by the dealership and the front desk guy put me on hold for 10 minutes for "an emergency with the boss". When he returned, told me that the only thing the shop did was check the calibration numbers (an evasive reversal of facts). He said "any remote reprogramming was done by someone offsite". I asked who that was and he would only tell me "someone in their network" and then quickly rushed me off of the phone. The dealer continued to advise that they NEVER adjust the computer under ANY circumstances from factory settings unless it is a brand new computer because it is a challenging calculation process and CANNOT BE DONE remotely. Of principle concern, the master tech at the dealership shared that the cheaper AFTERMARKET PARTS used could be part of the issue. This came as a shock after Andrei pushed so hard for Mopar parts and sent me the exact link and price for them. The dealership also notified me of OLD parts used in the repair. The owner is simply deceitful. Refused to take calls for over a week until I threatened action. I'm certain Andrei will reply w/ how they went "above and beyond" but believe me when I tell you it will be full of half truths and poor handling of a job they were unqualified to do for while charging me for OEM and using discount and used parts, obvious to the dealership.

I recently brought my 2003 Ford Focus into Top Shop Auto for what should have been a very…read morestraightforward issue. They charged $280 just to diagnose it, and even then, they weren't able to actually fix the problem because they said they couldn't find the part. For a car as basic and common as a Ford Focus, that didn't sit right with me. What was more disappointing was the overall experience. The communication wasn't helpful, and the attitude felt dismissive rather than solution-oriented. If you're going to charge that much for diagnosis, I would expect clearer answers or at least some guidance on next steps. It also felt like their focus has shifted since moving locations. There seemed to be a lot of attention on vintage and specialty vehicles, and less interest in helping someone with a standard daily driver. At this point, I'm getting a second opinion because I don't feel confident in the diagnosis or the value of the service provided.

I am reasonably confident that the intermittent starting problem has been fixed based on Fernando's knowledge and experience.

The price that was quoted was less than the dealership wanted, and was very fair. The owner was very friendly and knowledgeable. He was able to drop me off and pick me up from the local coffee shop, where I was able to work while the service was being done. When we got back to the shop, he showed me the brake test that was performed, as well as showed me some of the other cool vehicles in the shop. I am already in the process of booking a service for another one of my vehicles here, and see no reason for me to look anywhere else in the foreseeable future.

I'd been putting it off because finding the right shop (quality service, fair prices, honest recommendations, and not condescending) is so daunting. I enlisted my Dad who owns a dealership in LA to help me find the right Bay Area auto shop. He took the task very seriously and talked to 5+ shops. When he spoke with Martinez Auto Tech, he could instantly tell they were knowledgeable and they gave feedback on what was and wan't necessary for 60,000 mile service. Their prices beat out other local shops as well. When I dropped the car off they were able to take care of everything in one day (spark plugs, oil change, CVT drain and fill, brake flush, rear and front trans axel fluid) for under $1,000. To top it off they were so kind and happy to answer questions along the way. I never felt uncomfortable, unlikely majority of shops I've been to solo as a woman. 5 days later, our VW Golf died and wouldn't restart. I had it towed to their shop while they were closed over the weekend. I called them Monday morning to see if they could figure out what was going on. They were so accommodating and happy to squeeze me in without an appointment. They figured out it was an issue with the alternator and had the car back and running before the day was over. They didn't even charge me for charging up the car since I had just done my Subaru service. I really appreciate a small, local business that values their customers. This was such an act of kindness that I won't forget. I'll never service my cars elsewhere as long as I live in this area and will always recommend them to anyone - especially if you aren't a car expert and need honest guidance and recommendations. Thank you so much Martinez Auto Tech!
