What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Door strike plate in pillar mounted to sheet metal prone to fatigue. If issue is left undiagnosed the strike plate backing will come dislodged and allow the door to open while in motion.
The headlights did not come on automatically when the vehicle was started; it was after 9 pm and completely dark. The headlights would not come on even when the switch was used. I had to drive home using the high beams.
I was driving at night and the headlights went out. Everything else was working, I had dash board lights. The high beams work fine but not the low beams. Took it to the garage and found the low beam bulbs are fine. Checked all the fuses they are fine.
