Engine

109 reports1 crash4 fires
“Without any notice, the crankshaft seized while driving 55 mph on the highway. We were on a highway with one lane in each direction and a shoulder. No warning lights appeared until after the engine failed. We were barely able to coast to the shoulder at the time. The incident blew a baseball size hole in the engine. The vehicle was towed to over 60 miles to Noller Hyundai of Lawrence, Kansas. The repair was paid for under the Hyundai warranty without me providing any maintenance records. The engine is not in our possession for you to inspect, but I'm sure you could reach out to the dealership where it was replaced.”

Power train

18 reports1 crash
“On [XXX], my husband and I were driving on [XXX] (Highway) in the slow lane, when the engine shutoff without any Service engine light warning. 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 able to start after shutdown and had to be towed to my home. We purchased a new battery after assuming battery failure--with no resolve. The vehicle was towed to(two) 2 repair shops with the same conclusion: Seized Engine After checking Open Recalls on my vehicle, I contacted Hyundai to check for assistance. The vehicle is now at the Hyundai dealership in McDonough, Georgia for inspection. I am thankful that my husband and I were not injured or laying in a Morgue after this frighten ordeal on the highway when the Engine suddenly shutoff/Seized.”

Service brakes

14 reports1 crash
“I called Wayne Mazda on 9/7/22 to make an appointment to fix this brake recall and to have my car serviced. I was given an appointment for January 17, 2023, which is 4 months later. I called several times to try and get a current appointment and was denied each time, so I contacted Hyundai and filed a complaint. My case number is 20485596. Also my dashboard light showing low tire pressure stays on, even though AAA came and filled the tires. We are seniors and my husband is in a wheelchair, and I feel 4 months is an unreasonable length of time to wait for a brake (potential fire) recall and service. Any help you can provide with this complaint would be appreciated.”
