“I am an ase master technician, I own an auto/truck repair facility. We are a state of oregon authorized deq repair facility, state of oregon das fleet repair facility, us army base vehicle repair shop and more. Driving my truck to tacoma washington. I was towing a vehicle on in the right slow lane, and reduced engine power light came on. Engine vibrated and runs on 1/2 cylinders. Cannot brake or steer, total lack of power. Semi-truck nearly rear ends me as I cannot go over 10 MPH. No throttle response, period. …”

NHTSA complaint #10679355, filed 2015-01, 165,000 miles

“Extremely well cared for vehicle - always serviced at GM dealership, and recently safety state inspected. Brake line ruptured under truck cab leading to rear wheels. Complete loss of brake pressure. Complete loss of brakes. Inspection of brake line at the frame where rupture occurred reveals all lines leading to the rear of the vehicle are so corroded and rotten that I should be grateful this didn't occur at highway speed, otherwise, I would not be making this complaint. This failure should not be happening to a vehicle of this age and mileage.”

NHTSA complaint #10503720, filed 2013-03, 123,500 miles

“Brake line failure due to excessive corrosion of the line. After replacing the line myself, I performed a test run and yet another line failed due to the corrosion problem. The issue has been addressed by general motors in canada, but has not been addressed in the us. I feel that ten years and only 84,000 miles is not an acceptable timeframe/mileage to be experiencing brake line corrosion failure in the state of virginia. In fact the entire undercarriage of the vehicle is corroded far worse than my 2000 honda civic which has 175,000 miles on it. …”

NHTSA complaint #10557583, filed 2013-12, 84,000 miles

“Rusty brake lines failed upon application of brakes while towing a boat immediately causing complete loss of stopping ability. I had to have the lines replaced in a small shop due to location and lack of dealerships. Vehicle is meticulously maintained and only has 82000 miles.”

NHTSA complaint #10535274, filed 2013-08, 82,000 miles

“The contact owns a 2003 general motor SIERRA 1500 HD. The contact stated while driving 55 miles per hour, the vehicle would not come to a complete stop until the brakes were applied repeatedly. The contact noticed the vehicle was leaking break fluid which LED to the discovery of a rusting brake line. The vehicle was not taken to the dealer, and the manufacturer was not contacted.
