Rav 4 Door Rust

[arry191]

2004 rav4I have noticed spots of rust appearing on the inside of the doors at the bottom where the doors seal against the rubber seal first noticed this in early 2009 on 1 door and was repaired under warranty i have now noticed it as started on the front doors but toyota are refusing to repair them under warranty as they say the rust is not coming from the inside of the doors yet this part of the doors is on the inside of the car and does not come in contact with the weather just wondering if any body else as had or noticed the same problem i feel let down by the corrosion warranty dont think toyota are what they use to be also problem with alloy wheels very poor arry191
