Noticed the paint inside my door panel was blistering from rust underneath it the other day. How do I go about this? My vehicle is a 2014 with 46k miles so the warranty is out of the question. I did buy it CPO so I have that but I doubt it would cover this. Would fords corrosion warranty cover this at all? I just don’t want the paint to break and give me a massive headache. I also think it’s crappy that a 4 year old car that’s washed weekly has rust forming. Thanks in advance for any help!
