 Dt*: the contact stated the fuel gauge is inoperative. the fuel gauge shows empty at all times. the dealership replaced the fuel sender assembly, however the problem still exists. the manufacturer has been alerted. updated 7/21/2006 - the consumer's vehicle has exhibited the problem since the vehicle was new. many comoponents were replaced to correct the problem but none of them worked to permanently repair the problem. *nm

 I was leaving my driveway and completely lost all brakes and could not stop. i had to slam on the parking brake to stop. a brake line blew. all the brake lines and fuel lines are completely rotted.this vehicle isn't even 10 years old yet. the fuel line and brake lines are a major safety issue. this truck is a 2500 and i use it for towing trailers if that brake line went while towing it would have been a major accident. the entire underneath of this truck is so rusted the frame brake line and fuel lines are terrible. someone is going to get killed from gm's cheap steel. *tr

 Gm mailed a notice that the instrument panel in 2004 sieera trucks is subject to failure including fuel gauge, speedometer, etc. these can be very serious safety concerns depending on driving conditions. gm has offer to extend the warranty to 70,000 miles or 7 years. this totally unacceptable from a safety standpoint. *tr
