“Had failure of both rear brake lines and fuel delivery lines/sending unit due to heavily rusted/ruptured metal lines. Fortunately, the failures were observed in my driveway, leaking brake fluid and gasoline. The vehicle required towing to the local mechanics garage.total cost of repair (all rusted lines and fuel sending unit) at local garage was $875.00.”
NHTSA complaint #10045570, filed 2003-11, 98,500 miles“Diesel k2500 Suburban. Injection pump suffered a problem with intermittent fuel cutout. Solution was replacement of injection pump. Repeated dealer attempts to diagnose exact problem was not successful. Seat mount failed. This caused seat to tilt on base & torque remaining mounts. The wiper motor cut out at random. Gm acknowledges this problem for other models, but not for mine. This would cause failure of motor functions (in my case, the wiper would not start if parked, but would start if pulled out of park position). Brakes are the most interesting problem. …”
