Within that volume, owners reported 0 crashes, 0 fires, 0 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.

Headlight wires (Inside Housing) are frayed / melted. Can cause fire. I was replacing my bulb when I noticed the wires in the plug were completely stripped with no shielding. I traced it back to the connector and the wire shields were either frayed or completely gone

20220817STRUCTURE:BODY

Trunk failure. The trunk, when open, may suddenly fall very fast at any time. When you open the trunk it stays open but without warning may suddenly drop hitting you in the head. The trunk is actually quit heavy and can cause serious trauma to a person or damage to the vehicle as it slams down with force.

20220817AIR BAGS

Electrical system faulty. Front lowbeam headlight warning light on. Mechanic changed headlight bulb but it still did not work. After about a week the warning indicator went off and headlight worked. A few days went by and the indicator came on again. The low beam did not work. This time the left side marker lamp indicator came on and the bulb wasn't working. Before I could take it in for repair the side marker was working again. It goes off and on about every other month. Also, the indicator for one of the bulbs above my license plate goes on and off, but it says bulb malfunction. Now joining is the passenger side ABS light. Sometimes when I start the car the warning indicator on the instrument panel is illuminated but then goes off after I start the car several times, about a day or two. I never know which electrical component may not be working when I turn on the ignition switch. Sometimes no warning indicators will be displayed. The side marker lamp indicator hasn't been on
