Financed last year (2021) at 38,000 miles, financing a vehicle i wish I knew to do research before hestitly excepting my first offer, first waring was on the test drive. The car had to be towed back to dealership because the battery was dead. In the sub-zero cold, the battery with read low and this causes electrical issues, from remote start not working to unable to open the doors. The more common and reaccuring issue that is getting worst is the lack of excellaration when taking off. Realizing this drastic difference recently, I know there is some thing happening, but I have not had much good customer service when I have brought issues to dealership and services center. Also issues with harness for the back left lights. The harness that holds the bulb keeps burning out. Dealer has never fixed when I immediately experience this issue and they just replaced the bulb twice until they realized the real problem and told me it would cost me $160

Engine stalls while driving. No warning, intermitted full shut down of the engine. Can happen multiple times in a row, only making it a few hundred feet before stalling again. The only remedy is to put the car in park and start the engine again, however, that is not always easy to do when on the road, and the car can only drift and brake. It is not safe when the car stalls, especially in traffic -- can be dangerous to myself and others on the road if I am unable to pull the car over or get it to start up again on the interstate. I have been to a mechanic, and 2 dealerships who claim they cannot replicate the problem, and even when it stalled in the parking lot when I was leaving, there were no error codes on the computer. This being said, without a code or a proper diagnosis, I am at a standstill because "nothing can be done or authorized' by Hyundai without a code. I have been suggested by both dealerships to try and run it and 'kill the engine' because it is still under warranty for another 15,000 miles--but this puts myself and other drivers at risk because the car is unsafe to drive. There is a code from July 16, 2020, a little less than 2 months before I purchased the car about an engine light, this has yet to be addressed. This problem appeared out of nowhere one day while driving on the interstate and has been an issue ever since.

UNKNOWN - for the past several months, since my car hit the 70,000 mileage mark, my check engine light has come on while experiencing hard idling, delayed acceleration/power while driving - particularly on gradual inclines and hilly roads. I would suspect it has something to do with the power or fuel system. I have changed oil twice and had a diagnostic test done and mechanic is unable to pinpoint issue since it is not consistent.

When I put the nozzle to pump gas, the pump shuts off and clicks as if the tank is full. I have to twist the pump in one specific position and place it about 3/4th of the way in. Sometimes I have had to leave and go to a different gas station if the accordian plastic part of the nozzle is long. It just clicks and shuts off the pump. This happened from the day I first got the car, got gas and never ceases.

After a full stop and you press on the gas to move, at times there is a pause of perhaps 5 seconds before you can start to move into traffic.

When refueling the vehicle, and placing the nozzle into the gas refill port, the gas will cut off as if the tank is full. Only when the gas nozzle is inserted 3/4 of the way into the gas refill port will the gas flow uninterrupted.
