“Within the first month of purchasing this vehicle I started to experience problems rolling up and down the rear passenger window. It wasn't too long, then front window malfunctioned. The area of concern is for safety while driving in regards to rain coming in car and attackers. I would like to know that my windows are operating properly while stopped. The check engine light has also come on twice since new.”
NHTSA complaint #10523483, filed 2013-07, 500 miles“My car was stationary and the electrical system would not respond. This has happened multiple times now. My key fob would not open the doors, no inside electronics on, ignition switch did not respond. This appears to be a common issue regarding the battery cable connector and the corresponding fuse box terminal degrading over time. This could cause the car to stall and lose power while driving, which can result in a crash. I drive on the highway each day to work and a complete loss of power would result in a serious incident.”
