The rear sliding power door on the passenger side closed on my six year old child. He was trapped in the door and could not move until I opened the door. He has pain and visible injuries on his back from the door. This happened on 2.10.23. There have not been any incidents with the van leading up to this incident. This happened when the van was parked in the garage and the engine was off. We have not tried to replicate the incident because it caused an injury. The vehicle is available for inspection.
Our van has recently been having issues with the sliding doors. It has occurred while driving and the warning light as well as the warning for a door open, and the door lights have came on. Right before this occurs you can hear a click sound from the sliding door behind the driver's side as well as when you close the door, you can hear a strange sound when it closes, unlike the passenger side sliding door.
On June 6, 2019 at approximately 6 pm my vehicle experienced unintended acceleration. I was driving at 15 MPH and it accelerated to 40-50 MPH. Braking did not slow down the vehicle. I jumped the curb and hit three small trees. It came to a halt after undercarriage damage had been sustained. It was towed to cummings mobility where I purchased the vehicle. They could not determined what caused the unintended acceleration.

Power sliding door cable snapped. It happened to both door (right and left) about 6 months apart. Had the car for about 2 years not not even excessive use. The first time was at a dealership for vehicle service and they fix it for free since it happened there even though they said warranty does not cover. The second time was over this weekend and when I search online, many people experience the same problem. Poor quality cable (linkage) for the powered sliding door.
Right side passenger door, opened by itself while driving. My jids were seated on the back with grandma. Door also, closes by itself hurting the passenger who is trying to get into. It hurt several times my 8yr old daughter, my 11 yr old boy and grandma. Even closes when you are putting stuff in the passenger side.
