POWER TRAIN,FORWARD COLLISION AVOIDANCE — Filed 02/14/2024

ON 2/14/2024, my car started not to accelerate after the Crash Collision light came on. My car pulled off like it was a snail but picked up speed after I drove a bit. I had to put my hazard flasher lights on in order for other car not run over me, which was a major safety issues and put me and my grandson at risk of being hurt. There was no check engine light coming up just the warning flashed (only for a second) up (crash collision) and the symbol of car crashing into another vehicle with triangle symbol then it went away after awhile. I managed to make it to the car dealership but it took almost a month before they determine it was the camera and crank shaft. They repaired the vehicle from 2/14/2024 but two weeks ago the Crash Collision light flashed up again.(7/18/2024) I made it to the dealership again but now my car has been sitting for three weeks because they only have one technician. *Also, I am having a problem with the molding or plastic on my window. The molding on the window that stops rain for flowing down in your door has melted off on both window. The plastic/rubber molding is literally melting off and smearing on my window

While driving my steering wheel will lock up and I’ll get an error message for lane keep assist on the dash. I never use lane keep assist so even when it’s off it does this. I have to keep turning my car off and back on for my steering wheel to unlock and the error will disappear.

UNKNOWN OR OTHER — Filed 05/03/2023

When driving the car, it will intermittingly hesitate and as I press on the pedal the engine revs up but does not increase in speed. This has happened multiple times in the past month and is extremely dangerous. The other day I almost got hit by the car behind me and luckily there was an inlet I was able to pull into, stop and put into park, then when I put it into drive it worked again. As I came to next traffic light, it did it again and I was unable to pull over due to traffic, I put vehicle into neutral and then back into drive and it worked again to get me home. It took me 3 weeks to get an appointment with dealership and they say there is nothing wrong with it because it is not coming up on the computer. Very scared every time I need to drive it as I do not know when or where it will happen again.

In the manual car to get in reverse there is a "lock out" sling that only allows you to go in reverse when you pull up on it. When the manual stick shift goes back to neutral the lock out valve pops closed only allowing gears 1-6 The lock out is not coming down and is sticking so you think you are going into 1st gear but you are still in reverse. Basically imagine you go into reverse in a parking lot, putting it in drive and when you give the car gas it goes backwards. I have had almost 15 incidents in the last 2 weeks after I figured out what was happening. This is dangerous and has caused many close calls hitting other vehicles. I am bringing the car back to Huffhines Hyundai but only after a week of not being offered a loaner car and allowing me to drive in this car after at least 3 direct calls about the problem and the danger of having to drive the vehicle.
