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.”
