What owners say about the engine

Verbatim from NHTSA complaints, newest first
“I bought my 2012 Hyundai Tucson from a used car dealership back in November of 2024 . When I bought the vehicle it only had 55,000 miles on it and came with a 2 year unlimited mile warranty on the drive train and a full Carfax history in which everything came back clean , regular oil changes with synthetic oil every 4,000 miles and for my warranty through the used car dealership requirements I have continued to honor the every 4,000 mile oil change with synthetic oil every time . I have my Carfax that shows that my vehicle was brought to a certified Hyundai dealership back in 2019 for maintenance and the dealership never applied the required KSDS software update to extend my warranty. Flash forward to 8/06/2026 my vehicle with only 94,000 miles on it is sitting at a Hyundai dealership with the engine blown . I filed a claim with Hyundai and of course they denied it . I filed a complaint with corporate because it was at a certified Hyundai dealership back in 2019 they have had the updated KSDS software available at the time knew that it was a requirement for the extended warranty and didn't add the software update to my vehicle. I have asked for a good faith…”

“Vehicle suddenly slipped into limp mode. Vehicle was then immediately taken to have code read. Code came back P1326. Was advised due to previous recall campaign(s) to contact Hyundai of America for guidance. Was told that vehicle needed to be confirmed per the BCT at any Hyundai dealership to which the agent scheduled the appointment myself and that i should get the other 4 recalls fixed as well. My spouse drove the vehicle there and that was our last true communication verbally with Hyundai of America. Vehicle barely made it to the dealership and then spouse was offered a ride home an hour and a half later without paperwork or any type of understanding other than it would take time for the service team to get it on the BCT. A week later I was told it would cost $250. We have argued that we were never told it would cost anything as it relates to this major recall nor the others and in fact it would be performed at zero cost. Then, a service manager stated that now the vehicle needed $10k worth of work and began having finance firms contact me that he said were employed by Hyundai but are not. Here we are a month later, and still no vehicle and we have contacted…”

“Car suddenly stalled on the interstate (sudden deceleration, could barely make it to the shoulder; engine and oil lights, loud knocking sound, burning smell); per Hyundai dealership, it is sudden engine rod failure. Hyundai recall 181 described this exact situation. If not for quick thinking and moving to the shoulder/shutting down the engine immediately, there was a high chance of either being hit by other vehicles or engine fire. I could have been killed or severely injured. Yes, problem was confirmed by Hyundai dealership. No warning prior to sudden deceleration. Engine and oil warning lamps did not appear until after sudden drop in speed, followed by burning smell.”

“My 2012 Tucson started dumping large amounts of oil. Would be ok not dumping then would start drastically using then stop again. Vehicle ran fine then it started doing this maybe 3 months into this approx a week ago it started making noises coming from the motor. It is doing as I was told the motors Hyunda has recalled already done yet it is not listed in that recall. From what I understand it is a fire hazard as well as a road safety hazard due to it possible stalling. I have has 2 mechanics tell me it's pertains to the recalled motors. To see if it's a issue I'm expected to pay the dealership to evaluate this issue which is unfair to me You can clearly hear and see the issue is there. Why is it I am having to miss work, delay bills, be without transportation for them to acknowledge this concern. Please tell me there is a alternate solution help anything?!”
