In every Scenic I have looked at the front seats have split in exactly the same place. Renault replaced mine however my neighbours have not been so lucky. There is a design fault on the seats, Renault does not accept this...
My S reg front passenger seat split 2 weeks after I bought the car.
Nice car shame about the fuel consumption, wooly handling, diabolical brakes in the wet, poor build quality, road noise at high speed, indifferent dealers and mine has just developed a noisy a/c pump. Any body else had similar 'charectoristics'and found any cures. After reading the survey I'm quite grateful that mine ain't so bad as it could be!
