Body and structure: “In May 2023 a black plastic portion of the roof blew off the car. The plastic part that blew off was around the sunroof. There was no wind or blow to the car or anything like that; there was no prior warning or error message; there were no symptoms in advance. The part simply blew off the vehicle. The part is not available for inspection. Others were put at risk because the portion that blew off could have hit them or their vehicles. If the parts obstructed someone's view, there could have been an accident. …”

Transmission and drivetrain: “Hi, Improper gear shifting. Vehicle engine light comes on with Error Code P073E, reverse gear cannot be engaged Vehicle would shift gear back into neutral position when put to Drive. When vehicle is able to be put in gear Reverse or Drive, a loud noise and shaking would occur. When driven, vehicle is in Limp Mode and can only go up of Gear 5.

Air bags: “I was involved in a minor collision with a deer. I was driving alone and the deer hit my front passenger side. The airbags deployed. The knee bag completely destroyed the flesh on my entire right shin. It is one giant open wound that will take months to heal. I am short so I sit close to the dash. Had this knee bag not deployed I would have no injuries from the incident. The main airbag caused no damage so I feel I sit far enough away from that one. I am now scared to drive a vehicle with knee bags for fear of a repeat injury. I believe the knee bag is not safe for shorter people.”
