While breaking, rear driverâs side passenger seat disengaged. Our 8 year old son was in seat with seat belt on. Upon breaking the seat propelled him forward. His face hit drivers seat and he was lacerated and concussed. Not only did the seat locking mechanism fail, but seat belt lock did not engage or prevent him from being flung. Brought vehicle to dealership same day as incident. They claim to have attempted to recreate incident, but used an adult male (instead of a 50lb âdummyâ). Because they couldnât recreate the unlocking of seat or explain failure of seatbelt to restrain, was told nothing is wrong and they attempted to âclose the caseâ with nothing fixed, replaced or explained.
