2005: “While driving on a city street at approximately 40 MPH the vehicle started making a loud noise (similar to the sound a dirt bike engine makes). The sound became loluder when I pressed the brakes. I took the vehicle to the repair shop and was notified that the hydrobooster failed resulting in a steering fluid leakage.”
NHTSA complaint #10959113, filed 2017-03, 136,000 miles2003: “Started smelling strong fuel smells so took vehicle to dealer. Dealer called and asked me to stop back because when they dropped fuel tank they discovered fuel lines running from gas tank were so badly corroded through that were spraying pin-streams of raw gas all over the underside of my vehicle. Said it was a miracle I did not explode or catch fire. Mechanic then asked me to also look at every brake line on the truck which were also so badly corroded and deteriorating that he said they were a real danger as well and all needed to be replaced asap at huge expense. …”
