I was driving in the rain on 1/16/19 with my son, all of a sudden my car starts beeping and my dash board says stop driving now and check your charger system and after one hour it completely died, had to get towed home, now the dealer says the problem was the high voltage relay and connector that goes to the high voltage battery on the car that caused the battery to fail and charger system. Now I'm told I need to buy a new battery and I feel this should be covered B the warranty since this issued caused my battery to drain.

Transmission acts like it is slipping and shifts abnormally in forward and reverse, driver window up/down button doesn't work correctly it only makes the window go up 1/4 of the way so you have to let go and press it again. The radio keeps showing and error message waiting to get into the dealer

It has overheat problem that Hyundai service couldn't fix. It broke down 6 times and was 3 times in the shop. 4/2/17, I was on fastest lane on 101 freeway in downtown la. Suddenly the car alarm beeps. Dash board displayed "hybrid system warning, safely stop and do not drive". the gas pedal was hard to press, (guess it goes into protection mode. ) fortunately it was in rush hour traffic that no car Ram into me from behind. I forced the car switched lanes and exit freeway. After I parked, the car frozed. I can't turn on the emergency signal. Can't switch the gear to park, can't turn off the engine... I exit the car and wave cars behind me move ahead, then I got back the car and was able to turn off the engine. After it was off for 30 seconds, I can turn the engine back on and the car functions like normal. It was under 18000 miles. The service department says the coolant leak and replaced it. 5/15/17, while driving on freeway, I felt the car was into protection mode, hard to press the accelerator. But the alarm didn't sound off. I sent it in and the service couldn't duplicate the problem so they reset the computer of the car. 6/5/17 the car was parked in hot sun in ps for 30 minutes while me and my realtor go to check a house. I started the car following my realtor. I turned on the ac and the alarm goes off, same warning sign displayed and the car just froze. Hyundai sent a tow truck an hour later. After in the shop overnight, the service dept says they fixed it. 6/14. In ps again. The car was parked in hot sun. I got in and turn on the engine. Alarms goes off same warning sign. 6/26, with a friend on way to Julian, the car engine thrust the car forward, a small icon lit up. I slowed down and parked, the alarm goes off, same warning words on dashboard. After let the car cool off, I was able to drive but 20 minutes later it happened again.

About an hour into driving home on the freeway, my car alert system went off and the car automatically began to decelerate and the dashboard display showed instructions to check hybrid charging system and to check surroundings and to pull over when safe and to not drive vehicle. The check engine light, the needs maintenance light and the check oil light all came on. After about 15 secs my vehicle lost all power but did not turn off; the steering wheel became locked. I placed the car into park and restarted it and the warning alert alarm ceased, but now the check engine light stayed on. The steering wheel was movable again and I was able to pull to the shoulder where a California highway patrol officer pulled up and asked me if I was having trouble. After our conversation, I was able to continue the additional 40 mile drive home as the local Hyundai dealerships were closed until the next day, Saturday March 18. I was able to drop my car off in the afternoon but due to their booked schedule, it could not be looked at until Monday March 20th and stayed over night. The technician called me that day and stated that the car test ran on it came back passing and no issues found and that they drove it about 20 miles and no issues and I was able to pick up my car on Tuesday. However, the same system issue happened 3 more times before I was able to take it back into the dealerahip later that week and it has been there as of 4/21/2017. I received a call today that a replacement hybrid battery was installed and after more tests I may get my car back.

When pressing the accelerate pedal there seems to be a delay in response. The delay can be as short as a few milliseconds to almost 3 entire seconds. This problem happens randomly, and makes my wife and I very nervous when trying to maneuver or proceed into traffic after being stopped.
