“The contact owns a 2002 Cadillac Escalade. The contact stated that while driving at various speeds, the vehicle was consuming an excessive amount of fuel. There was no warning light illuminated. The vehicle was taken to an independent mechanic, where the contact was informed that the fuel pump needed to be replaced. In addition, the contact stated that there was an abnormal scraping sound coming from the front wheel hubs on the driver’s and passenger’s side wheels. There was no warning light illuminated. Additionally, there was brake fluid leaking from the brake lines, causing the braking distance to be extended. The contact was provided with an estimate for the repair. The vehicle was not yet repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 200,000.”

Neither my friend or myself are mechanically impaired so We made the exchange of ownership and went on our way home. When we arrived my step father felt the need to investigate the issue. He discovered that every brake line under the drivers seat back approximately 24” were so rusted and soaked with brake fluid that fluid was dripping and making a puddle and was unable to pinpoint where the hole was at that time. We decided that the vehicle was too dangerous to drive, and returned to [XXX] to retrieve his trailer to bring the Escalade to his shop for safety reasons. We tried researching and did find where GM’s SUV’s did have a recall on this matter. The Cadillac is in excellent condition inside and out. The leather seats other than the drivers show no wear at all. Carpets show no wear. The exterior is in excellent shape without chips or dings. Basically a like new with 104,000. Miles which is…”
