As you start and stop the car the drivers seat rocks back and forth. It's very disconcerting and scary to the wife. She complains the seat is gonna throw her out of it if she had to apply heavy gas or brake.

middle rear seat slides forward - suddenly

While slowing down, the centre row, left hand side seat suddenly became unlocked and slide forward, Seat would no longer lock, Dealer asked us why???. They took the seat apart and found a defective part. Two weeks later it was fixed. In the meantime I had to put 2X 30 kg salt bags in between the front and centre seat to prevent it from slamming forward at the slightest touch of the brakes.

The seat moves on its track when hitting the breaks.

Driver's seat became loose in the track and moved upon braking or acceleration. Replaced under warranty after inspected by dealer.
