Update (1 4) 4/7/26: Issue resolved, but the process revealed areas that need improvement…read more While my initial experience involved multiple visits, ongoing noise concerns, and frustration around inconsistent diagnoses, I do want to acknowledge that the issue has now been resolved. The A/C compressor was ultimately identified as the source of the problem--something that should have been caught earlier given the number of prior inspections. It's also important to note that these issues began following a routine oil change at the dealership, which led to an oil leak involving the oil pan, oil filter, and drain plug. My vehicle had no prior issues before that service, so this was a significant concern. I want to recognize Jaime (Service Advisor) for his consistency, professionalism, and commitment to helping move things forward. I also want to highlight Ali, the lead technician, who ultimately identified and resolved the issue. Additionally, Lisa (Service Manager) kept her word in working to get my vehicle back to the condition it was originally designed to be in. She listened, acknowledged both the issue and my concerns, and made a clear effort to address the situation. That was appreciated. However, I do believe the Service Group Director and Director of Operations could have been more proactive once this situation was escalated, especially with corporate involvement. More direct communication and leadership at that stage would have made a difference. I also want to note that I requested goodwill consideration from Hyundai multiple times throughout this process and have not received any. Given that this issue began in early January and was not fully resolved until the final week of March, after multiple service visits and extended time without my vehicle, I believe goodwill consideration is warranted and should still be evaluated. I am relieved the issue is now resolved, but the process to get there should have been more efficient and consistent from the start. I hope this feedback helps improve both diagnostic accuracy and communication moving forward. I'm sharing this update to reflect both the resolution and the full experience so others have a complete and accurate picture. Update: Picked up my car on 3/18. Thought the issues were fixed. Since picking it up, the issues are still there. They never fixed my car that they messed up after the oil change. I will be reaching out to corporate about this issue at this point. I've been coming here since 2024 and never had any issues with them. However, this past December I got a oil change from them and it messed my car up. While driving my vehicle in February, the oil lamp came on (It means that I need a oil change). I did not understand why because my vehicle was not driven much due to several vacations taken from Dec to that date in Feb. I have a 2023 Sante Fe. Very good on gas and oil. I contacted Hyundai immediately and they had my car towed to them. They diagnosed the issue. They stated that when the outstanding change had been done, the oil pan was not properly placed back on which caused an oil leak. This issue caused then to have my car for 2 or 3 days. They never offered me a loaner nor rental. I had to stay home from work for all those days. Honestly, I did not ask them for one because I did not even know they offered them. I never had to receive either before. Fast forward, my wife begin to notice a rough noise (My car does not make any noises or gave any issues. I have always kept my maintenance up since 2022 when I first purchased it). So when this noise happened, I did not understand why. That noise came on when you automatically started the vehicle, at stop lights and at red lights. It is horrible. This lasted for 2 weeks until I was able to get time off from work. In the 2nd week, the ac/ heat until began to also make noises. This was ridiculous. I finally got off 3/12. Took my car in.. there is a new guy there (Service Advisor) that really listened to my issue and even sat in my car for some time to great what I was hearing. He was very empathic. Jamie (Service Advisor) also showed empathy. She was not happy to hear that there were more issues with my car after the oil change. I explained to get that i needed a vehicle this time around because I had an appointment the next day. They had no loaners, but she got me a rental via Enterprise. Jammie gets 5 stars from me each and every time!

DO NOT DO BUSINESS WITH THEM. You guys are SLEAZY. YOUR DEALERSHIP should wonder why you have MANY…read moreCARS ON YOUR LOTS that are ALMOST A YEAR sitting there! A YEAR! PUSHING 300 days. Lol. THAT SHOULD TELL THE OWNER YOU GUYS ARE HORRIBLE BUSINESS MEN! Funny thing is you'll act like you're giving a customer a major deal but the deal is complete and utter bullshit! Again wonder why your cars are still sitting on your lots. Lmao. You guys thought you would play me and I would fall for your bullshit offer even knowing I was getting 2k off from other dealerships. Then you add an accessories package for $200 that I specifically told u I didn't want any add ons. You tell me it's on all your cars. I don't give a shit that is your bad take the price off. Period. You don't want to make a deal you didn't want to do the right thing matching another offer from another dealer. Tried to tell me you were being transparent. Lol. YOU LOST out! That's what happens when your unethical business men you lose business and can't finalize a deal. I work in sales so I know what to do and what not to do and that is to be dishonest and try and pull fast ones on people. That is exactly what you guys try and do. To ALL the yelp readers do yourself a favor GO TO VACAVILLE HYUNDAI! The men there are ethical and they want to make a deal! Specifically GO SEE MALEEK AND DANIEL! MALEEK WILL GO OUT OF HIS WAY TO FIGHT FOR YOU AND GET YOU A DEAL THEY'RE NOT PUSHY ON THE BS EITHER! Those are the men you want to do business with! GO TO VACAVILLE HYUNDAI ALREADY! They are worth the drive trust me! LITTLE ADVICE TO THE OWNER OF THIS DEALERSHIP: When you hire men make sure they're ethical bc when you have ethical people working for you, your business will come back ten fold! You'll get referrals and you will get cars off your lots. When you play dirty you will remain where you are. Cars sitting there for 300 days. Do better and Be better.

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!

As for the truck, I also want to acknowledge Abdul, the sales manager, for stepping in and making things right there as well.
