The brake lines are rusted from the rear sub Frame that was rusted And caused an accident. They told me the sub frame was the only item covered but that they could only bolt it and not weld if and then the exhaust and brake lines (rusted too bad to describe) weren’t covered and since I couldn’t afford it they only repaired the subframe and left the rest hanging ! My brakes failed on the way home. No one was injured but I can’t believe they let me go home with that condition!

There is currently an extension of warranty for only the subframe in rear, but the rust is extended beyond that and is applied to the components needed to be removed in order to replace the subframe.

My vehicle has excessive rust issues that I’m being told by the dealership will compromise my safety. There is currently an extension of warranty for only the subframe in rear, but the rust is extended beyond that and is applied to the components needed to be removed in order to replace the subframe. Such as the exhaust pipe and brake lines as well. All are corroded to a high degree up to and including complete brittle material Disintegration. Exhaust and rear brake line cost make it impossible for me to have the vehicle brought back to safely drivable conditions. I have to get to work daily or my family will not eat or have a roof but at a cost of more than what the car is even worth I have no choice but to choose and compromise my safety and those around me or food and shelter for my family. Please help.

THE EMERGENCY BRAKE LINE CAUGHT FIRE UNDERNEATH THE ARM REST COMPARTMENT. TRACED THE LINE BACK TO REAR TIRES AND NOTHING ELECTRICAL COULD BE SEEN TOUCHING BRAKE CABLE LINE. SO NO OBVIOUS REASON WHY CABLE WOULD IGNITE. I WAS PARKED IN CAR PORT STALL AFTER A SHORT TRIP TO A FRIENDS HOUSE.
