“In park after car has sat over night or for 24 or more hours, the car will start but will not move into gear the car has less than 50,000 miles on it I have had regular oil changes. I am afraid to go very far for fear I won't be able to start the car and get home. My driveway is gravel and a little bit of an incline. Today was the 3rd time in this week.”

“My car started making a growing sound when I press the gas it gets louder and louder as I drive . It almost sounds like a lawn mower it's been 3 days now and it's also as of tonight struggled to turn on and when it did the growing sound was exaggeratingly loud . So if I drive it sounds bad and when it's parked and gets turned on the sound is bad it's a lose lose”

NHTSA complaint #11406692, filed 2021-04, 126,000 miles

“As I was driving on the highway at 75 miles an hour in severe traffic car started to make noise and blink check brake. Then it started to slow down to around 10 miles an hour and new message was hybrid system warning do not drive. If I was not on the end lane I would have been in an accident. My kids and partner are traumatized. Very dangerous design needs to be looked at.”

NHTSA complaint #11321262, filed 2020-04, 90,000 miles

“With a odometer reading of just under 135000 miles a warning light came on with a message that the hybrid battery was not being charged and then the engine developed a serious knocking sound. We pulled over to the shoulder of the highway. After having the car towed to the Hyundai dealership we found out that metal shavings in the oil meant that we needed to replace the engine”
