Same here, 2018 Santa Fe sport ultimate with 114k lost power on the highway. They determined it was cylinder 3 with non compression and denied a good will repair after thinking about it for 10 weeks. I just posted this on BBB
I am writing to express my deep disappointment with my recent experience with Hyundai. As a loyal customer for over two decades, I have always been a strong advocate for the brand, recommending Hyundai to friends and family. My three daughters even drive Tuscons and love the vehicle. Unfortunately, my recent encounter has significantly eroded my trust in the company.
I purchased a 2018 Hyundai Santa Fe Sport and am the original owner. In total, I have owned nine Hyundai/Kia vehicles since 2003. Throughout the years, I have consistently maintained my vehicles at authorized dealerships and have always been satisfied with the service. However, I have noticed a recurring issue with excessive oil consumption, even after regular oil changes. I was informed that this is a common problem with turbocharged engines and that the oil is simply burning off.
A few years ago, I received a letter from Hyundai stating that the engine now had a lifetime warranty due to the known issues. This reassurance gave me peace of mind, knowing that my engine would be covered for life.
Unfortunately, in July, my car lost power on the highway. After investigating the issue, my mechanic determined that a piston was not compressing properly, likely due to the excessive oil consumption. He recommended taking the vehicle to the dealership for warranty repair since it was a lifetime warranty. He even called the dealership who confirmed that they were experiencing a lot of problems with these engines.
I brought my vehicle to the dealership, expecting them to honor the lifetime warranty. To my dismay, they informed me that the engine's "bottom part" is covered under the warranty, but the piston is not. This is despite the fact that numerous other Hyundai owners have experienced similar issues with the engine.
I reached out to Hyundai's customer service department and requested a goodwill repair. After a frustratingly long wait of over two months, my request was denied, citing the vehicle's mileage as being beyond the warranty period. As a loyal customer who has consistently chosen Hyundai, I expected better treatment. The denial of a goodwill repair, coupled with the lack of any type of appeal process has left me feeling betrayed. The case manager was even surprised by the decision, given my longstanding relationship with Hyundai, the consistent maintenance I have provided, and the relatively low amount of milage over warranty.
It is truly disheartening to see a brand I have trusted for so long fail to stand behind its customers. I am now considering selling my Hyundai and purchasing a vehicle from a different manufacturer. I hope that my experience will serve as a warning to other potential Hyundai buyers and that the company will take steps to address the ongoing issues with its engines.
I am sharing this experience with the BBB in the hope that it will help other Hyundai owners be aware of potential warranty limitations and the challenges they may face. Do your research before you buy a
new Hyundai!
