I know the investigation is closed on rusted brake lines but id like for it to be reopen. i am not sure why the nhtsa is not finding gmc liable for this negligence. brake lines rust from time to time. we got it. but my 2006 denali is driven approx. 4,000 miles per year, garaged when not driven. i live in an area that some years it doesn't even snow. so i don't want to hear its the weather. i was surprised at my local mechanic's garage at inspection time when he showed us the parts that needed replaced (i have those in my possession btw). its not the weather that's doing this for the sheer fact that its primarily gmc that has the problem. no other car manufacturer has had this problem to such an extent. my family is a camping family and towing an 8,000 lb camper with rusted brake lines could have meant disaster. thank goodness our mechanic noticed this. i have tried seeking reimbursement through gmc and of course they don't want to reimburse me for this. i paid almost $800 for this work to be done. i want reimbursed; its only fair. we teach our children that when they are negligent they have to make things right. our legal system is one in which if you cause an injustice you have to make things right times three. again, its gmc that is having this issue and my car doesn't fit into "oh its a weather related issue/wear and tear issue". please reopen this investigation. i think the public will demand it and i may look at joining a class action lawsuit against gmc. i expect to hear from you.
