Consumer stated that while driving and without warning, the egr valve failed, which caused the brakes to fail. Dealer notified. The mixing with the fuel was the biggest problem. (when there was carbon build up in the egr valve, it would leave it open and caused no vacuum hard pedal and brake failure. When it rained or was cold the truck ran rough. The service light came on when the vehicle had run rough more than once, noise was present and there was a smell of burnt wires and the ignition switch was replaced, the brake pedal seemed soft on more than one occasion and the master cylinder and other brake components were replaced to try and solve the problem, the cd player had not worked since the ignition switch was changed, the rear windshield wipers had become inoperative, a noise would occur when turning but was not duplicated, and the muffler tail pipe had fallen off and rusted due to carbon build-up. The egr valve was cleaned but the problem persisted. The mechanic stated that in order to perform a proper job, the excessive carbon build up in the upper and lower intake manifold which effected the egr pendel, and the 02 sensor could cause a problem with the exhaust system, catalytic converter, fuel pump, the brakes, etc. The brakes squeaked, there were no dash lights, no air conditioning, and no 4-wheel drive. The fuel injections needed to be checked, and there were two recall stickers on the engine. The rear wiper motor, fuel injectors and brakes were replaced.
