Summary of Complaint
In mid February/early March the brakes failed while the vehicle was moving in a parking lot. After exiting the vehicle with the emergency brake on, I found a pool of brake fluid under the car. After towing it home, I had to make the decision to leave the car sitting as I did not have the financial resources to take it to an authorized mechanic as I had lost my job in January. In May learned of the recall and called the number, only to be told that I have to wait for a letter in the mail and to do nothing until I receive a letter. After roughly 2 months we received that letter, and the only instructions were to set up a service appointment, which I did at their earliest date available, which was 20 days later. As the car sat undriveable for months on end the lines clearly corroded further and further, and the battery was also damaged by sitting uncharted for that period of time. So when they received the car, they would not repair the car until the battery was replaced, which they would not cover even though they are clearly the cause of that as well. Then, four days after receiving the car, they have decided that the brake failure was caused by excessive corrosion (which was not there until the car sat for as many months as it did) and they would not cover the repair nor finish the safety recall, and as I type this, have not confirmed if they are even going to cover the tow back to my home(over an hour away) so that I can perform the brake line repairs myself. I find all of this extremely hard to believe as we purchased the car less than two years before the incident and the steel lines were inspected before we picked it up. I understand corrosion can cause failure like this in extreme situations over long periods of time, but I do not believe that it was not caused by their neglect. I am desperate for help at this moment.
