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.

As I was driving down the road, a warning sign appears in my dash that says do not drive.... Mean while im already driving.... Cars starts to stall and wheel locks. I get the car towed to the dealership that night and the next day... Which is today I am waiting for someone to call and ask me what happens and nothing... So I decided to drive there and what do I see..... My car sitting on the side like no one cars that is there... When I go in I find out that there is only 1 person that works on hybrids and they don't know when they will be able to take a look at it... Oh and lets not forget they don't do loaner cars.. I just bought this car 1 year ago from this same dealership...they cant give me any type of estimate of when the tech will be able to look at my car... This is very bad service!!! Why would my car stop driving after having it only a year?????
