In owners’ own words

My wife was pulling into a parking place at Home Depot when the car suddenly accelerated, jumped the curb & hit a tree on the sidewalk. It did significant damage to the front bumper of the car but the airbags did not deploy & my wife was not hurt. I am guessing that it will be several thousand dollars to repair
Our car stalled out multiple times within a 5 min increment. We took it to the shop and it has been there for over 30 days. We have no case manager from Hyundai and no estimated time for a fix. We're getting charged out of pocket for a rental that is going on for 30+ days and Hyundai will not: 1.
On 30 May 21, I was getting ready to pull into my driveway, stopped the vehicle to let a passenger out of car, when suddenly the vehicle accelerated at a high speed crashing into my house. I nor the braking assist could stop the vehicle, resulting in the collision with house. I and my passengers sustained seat belt injuries
Dears, I have been contacting both the dealership and the manufacturer to assist with the recall, no help whatsoever. I had this issue before the recall and the car still has a similar issue, I cannot drive it and in the same time I don't have another car. and I cannot risk my life or my daughter's being in the car.
Car has been taken in numerous times for emmisiions related issues to vent pipe and charcoal canister. Still getting same check engine codes. Frustrating since inspection is due. I contacted Hyundai corporate
