Hyundai is denying an engine replacement under their extended warranty under the KSDS software update (Campaign 966) because the software update wasn't completed. However, Hyundai failed to notify me of this requirement; I purchased the automobile in Jan 2024. The KSDS recall was sent out in 2021. I recently received an official physical mailer…

The car continued to use oil, and the dealership had us replace the catalytic converter two more times, so three times total. Now the problem is occurring again and they are recommending replacement of the catalytic converter for a FOURTH time. We have filed a claim with…

As it was nighttime, my husband and /or other motor vehicle drivers/passengers could've been seriously injured. The car did not display any warning lights or signals. The car was then towed home and then to Empire Hyundai in Fall River, where it…

   The engine failed two years ago at 86000 miles. Hyundai replaced the engine for it to start knocking and stop working a year later. I completed all of the first oil changes, slow driving, ect. Seems like an engine problem with Hyundai itself.

    I started having oil issues 3 years after purchasing my hyundai Tuscan 2015. I took my vehicle to hyundai several time all of which I was told by service guy and I quote “Hey its Hyundai, just following up so right now we have a consumption issue. It is currently 2.5 quarts low. The tech recommends re doing the oil change and returning in 1000miles and recheck. When you return and we see that the oil level is more than a quote low then we would have you reduce the service…

It was frightening because an tractor trailer was directly behind the car as we lost power. There was no sounds of engine parts knocking or pinging when the problem occurred. The only thing was observed was (two) 2 puffs of smoke seen from the tailpipe, witnessed by my son who was following behind in his vehicle. The vehicle was not…
