I have a Corsa D. I got it new in 2010. A big bit of rust fell off so took it into the garage - it's a Vauxhall approved one. I've taken it there every year and paid ++ just to keep the Lifetime Warranty up. They say the sub floor is rotten and needs replaced. Any idea of cost? Shouldn't they have picked up on it at the last service/MOT (end Sept 2019)? Is this a known fault? Do you think Vauxhall would help with the cost?
Theoretically, how long does it take for a sub floor to get that bad?
