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.

A few months ago the vehicle stalled at a red light. I found complaints of the same make, year and model stalling on other owners on the internet. Went to dealer and after numerous hours in the shop they could not find the problem. Today my 19 year old daughter was on a four lane highway with no pull off lanes, only cement barriers. The vehicle stalled at 60 mph. She almost died from being hit by a tractor trailer. She was missed by only a few inches. The vehicle did start again and she got off the highway. Made complaint with Hyundai Consumer Affairs.

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.
