I've had my car for less than 2 years and the battery completely drained/dead. Hyundai refuses to cover it under the 3 year warranty due to my car having over 36k miles. The car was brand new when I purchased it and I've never had a car battery died so fast ever in my life. Also, sometimes the backup camera won't turn off and will stay on even after driving frond for more than 10 minutes. It will only turn back off if I turn the car completely off and then back on again.
