11/10/2020 as I was driving I noticed a burning smell coming from the outside of the car I had my windows down I pulled over in a grocery store parking lot because I thought the smell was coming from someone else car only to find out it was mine I only had the car for a little over 6 months the car had 2552 miles on it I reported to Hyundai customer service only to be disappointed and given the runa round. I have a case number as well #17456723 I spoke with 2 managers and I was being told oh this manager handles this and then when I spoke with that manger I was told I had to speak to another manager, so I had the car towed to a dealership to only be told that they couldn't determine where the smell was coming from and don't worry about the smell on the outside of the car but they had performed a recall on the vehicle where I wasn't even informed about the recall from Hyundai even when I went on the recall website there was no open recalls listed for my vehicle so I got frustrated and had them repossess the vehicle because I refused to risk my life by continuing to drive the vehicle with the overheating issue I also noticed that the thermostat would rise really quick and the car wouldn't even be running that long and it even took them a week to come get the vehicle now I'm being told that the car will be auctioned off and what ever they don't get for the vehicle I will be responsible in which I don't believe is fair after complaining that the dealership told me that the original dealership where I purchased the vehicle probably sprayed something on the engine to keep it from rusting I was upset because I never took it back to the original dealership of purchase I explained this to the manager as well I was told to take the car some where else I couldn't I have medical issues I am dealing with and that would have been to much for me.

2/20/2020 - I was driving my new 2020 Elantra (less than 5,000 miles on it) and I noticed the car was not accelerating smoothly. The RPM needle was revving abnormally whenever I tried to accelerate. When I pressed the gas from a dead stop the car would shutter before accelerating. On my way home from work the same day I was having the same issues but as I merged (turning) onto a highway the car suddenly stopped accelerating all together and I was not able to go more than 10-20 mph. Since it was at a merge there was almost a collision, but I was able to pull over before anything happened. 2/21/2020- the next day while I was at work my husband tried to drive my car to the dealer. He experienced the same issues and when he got to the dealership he was unable to turn the car into the service station because the car would not accelerate. Service workers had to push the car into the bay to be looked at. The employee told us this was about the 15th 2020 Elantra they have seen with the same transmission issue. No emergency lights came on in the car during either incidents. Since no lights came on during the incident, I was very hesitant to drive the car again.
