Making a right hand turn and I believe the truck in front of me lost the trailer hitch. I was only traveling about 15 mph. Drove over a trailer hitch in the road and all the airbags deployed, causing a violent stop to the van and injuries and shock to my daughter and myself.
The intermittent wiper is reveresed. The slow is running fast and the fast running slow. Took it to the dealer and they advised that they could not do anything. Also the dash is not flush with the instrument cluster.
