The contact stated that the failure was a recurring failure. The dealer was contacted but could not duplicate the failure. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 39,000.”Owner report · Service Brakes, Hydraulic · Jul 2026
“When loading groceries in my trunk, the door randomly closes on my head. The last time this door closed while we were loading, I tried stopping it with my hand, by holding it, so my spouse doesnt get smashed, and it will not stop at all. There needs to be a safety feature installed to stop this trunk from closing if a person is underneath it. I fear that a child or an elderly person wont be able to move fast enough and will be severely harmed by this.”Owner report · Unknown Or Other · Nov 2025
