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.

On sat, Oct 1, at about 1 pm I was about to complete parking the vehicle in the parking lot of the huntington beach branch of chase bank. I fortunately selected a site on front of a planter section with bushes, as otherwise there could have been injuries or property damage. I was almost stopped and was about to put the gear in park, the car suddenly revved up the engine and accelerated violently and with great force, propelling the car over the cement curbs of the planter and landed in the bushes. The car could not be reversed out of the bushes as the wheels were lodged inside the planter area. The front bumper, position lights and undercarriage were seriously damaged. Aaa road assistance had to be called to pull the car out of the planter. The incident is extremely similar to other such incidents of sudden unwanted acceleration documented in youtube videos. We have opened a claim with Hyundai, case # 962 9876.
