I was driving at 55 miles per hour and the truck just stopped running. There was no warning. I had to pull over fast to avoid an accident. The truck only has 40,000 miles on it. The dealership says that it is a fuel cell and that it is not covered under my 100,000 mile warranty.

State inspection, failed due to rotted fuel filler neck. Was told for awhile it was due to gas cap, replaced that, light would go on and off. When it would no longer go off took back to dealers. Dealership replaced fuel filler neck, along with valve/sensor at a cost of over $500. Gm will not help as they claim it was due to "environmental factors" (we live in MA). Also, parking brake backing plates rusted out, e-brake cables frozen, had to replace those at another $850. Old parts not available, dealer repaired.

The truck after 40 miles started screeching from the front when going around corners,and was reported to the dealer sam swope, I was informed that it was normal, on the way to town the truck stalled and was towed for repair turns out the coil plug shorted out wires were replaced, next day the truck stalled again towed again turns out that booth catalytic converters were plugged,booth replaced. Entering the freeway when accelerated the truck did not respond, I was informed by the dealer that nothing wrong with the tranny, now I have a clunking noise from the rear of the truck they claim not to be able to duplicate the problem, tires worn out at 27,000 miles turns out alignment problem but no cause for the squealing tires sense first reported the first day of owner ship. Same problem all the time steering wheel never been aligned anti-lock brakes never work right always locking up on breaking first thing in the mornings and the dealership not able to reproduce the problem. This truck is dangerous to drive with to any failures.

: the contact stated there were two problems with the vehicle. First, the fuel gauge worked intermittently, but the vehicle has not been inspected by the service dealer concerning this issue. There were no warning indicators prior to the intermittent failure of the fuel gauge. Second, the passenger window dropped into the door without warning. The vehicle was inspected by the contact and it was discovered a cable was broken that held the window in place. A shim was added to keep the window in stationary position.

The gas gauge in the consumer's 1999 GMC Sierra failed. Consumer feels that the cost of repairing the part was too high. The consumer has spoken to other owners with the same problem and believes the manufacturer should have recalled the part.

When starting up the vehicle it ran roughly, and a smell of fuel was noticeable. Consumer took the vehicle to an independent mechanic, who diagnosed the vehicle and said it was the plenum chamber and gasket that was causing the vehicle to smell like fuel when starting up.

My gas gauge on my 1999 GMC Sierra has not worked for over two years. Cost of repair to high.

When the air conditioner (a/c) is used it takes at least eight minutes for the cool air to flow. There is a foul odor coming from the vents that smells like rotten eggs. Also, consumer is concerned with the sound of the engine. Although the vehicle is equipped with a gas engine, it sounds like a diesel engine. There is a irritating noise that occurs intermittently at any speed. The dealer claims that the noise is normal. Engine burns 3 qts. Of oil every 3000 miles and the fuel gauge isn't accurate.

Fuel gauge sending unit failed @ 57k miles. Called gm. No satisfaction. Cost to replace, with labor, is $700!!. . For a toilet bowl float??!! sheesh! haven't fixed. Replacement cost is outrageous and it shouldn't have failed to begin with, especially not that early.

Fuel gauge low fuel light comes on intermittently even after just filling up and fuel gauge bounces all over the place.

Possible fuel system failure caused the motor to shut down while driving. Yh.
