Brakes all 131 →
Tl* the contact owns a 2000 GMC Sierra 1500. While driving 50 MPH, the vehicle had a sudden loss of power steering and the brakes failed to engage without warning. The contact mentioned that the vehicle would veer to the right independently. As a result, the vehicle crashed into a concrete barrier and spun around from the front and crashed in the rear. The drivers side and front passenger side air bags deployed. The contact sustained a dislocated left shoulder and a fractured right foot. The contact also sustained whiplash, neck pains which required medical attention. A police report was filed. The contact was not included in NHTSA campaign id number: 05V005000 (power train) and NHTSA action number: ea04012 (service brakes, hydraulic, steering). The vehicle was towed to the contacts residence. The manufacturer was notified of the failure. The approximate failure mileage was 183,500.
During a normal stop at a stop sign on a rural road, a steel brake line ruptured due to excess corrosion. This one line between the master cylinder and ABS module is the only line that provides pressure to the front brakes, which supply roughly 75% of the vehicle's braking power. The rupture resulted in rapid fluid loss and therefore a lack of pressure in the hydraulic system to allow for adequate braking. Needed to swerve into a ditch to avoid a crash with cross traffic.visual inspection indicates most brake lines are extremely corroded, and were obviously made with substandard materials as compared to other manufacturers. I do recognize that this is an old vehicle, however other vehicles of similar age and driven in similar environments do not have this issue. …
Fuel & propulsion system
I started smelling gasoline and found a corroded fuel line at the junction between the nylon line leading from the fuel pump to the steel line going to the fuel filter. Doing repairs, the hard brake line leading from the ABS unit under the driver's seat area to the rear flex line connector was leaking badly as well at the rear-most fitting. Purchasing these lines separately cannot be done, so I'm replacing all of the fuel/brake lines myself. I'm using stainless tubing for the brake lines not provided by factory GM parts.
I have a 2000 GMC Sierra that had brake line rust through causing brake failure. I got under the vehicle to try and change the line and found all the lines are severely rusted as is the fuel lines. Yes my truck is old and I live in the rust belt of n.y but something needs to be done either n.y stop using salt or the vehicles need to be built with lines that don't rust out. This issue I think is a safety issue that would be easily fixed by either no more salt or better line in the vehicles that don't rust through.
