Consumer Description

After an update for a recall for brake issues, the dealership updated the knock sensor update without my consent. After the knock sensor software was installed, my 2012 Hyundai veloster will not operate without going into protection mode. Hyundai states that they can not reverse the software update to make my vehicle operable again. This has already come up as a safety concern as my wife was on the interstate when the vehicle shut down in 70+ mph traffic.
