I was coming to a stop and I lost my brakes I was able to get it stopped. Took it to my mechanic right away and was told the brake line burst and hit my gas line busting it as well. They had the vehicle for over 3 weeks. They repaired the gas line easy enough but the brake line had to be completely replaced.

Tl* the contact owns a 1999 gmc sierra. The contact stated that while driving various speeds, he smelled a strong gasoline odor inside of the vehicle. There was also fuel visible on the ground. The contact inspected the vehicle and noticed that both the fuel and brake lines were completely rusted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the problem. The approximate failure mileage was 71,000.
I was returning from hunting trip ,and when I got off I-75 freeway to go to my home traffic signal ahead was red and pedal went to floor. Fortunately,the light switched to green and I was able to maneuver to not collide with car stopped ahead. I nursed it home via back streets at very low speed and to the repair shop the next morning. Mechanic replaced brake line. The fuel line was rusted out at the fuel filter and discovered while other maintenance was being performed. The undercarriage is extremely rusted and I am concerned about pulling my travel trailer due to rusty condition of things. Rocker panels are rusted out as well as rear fender wells. Surely gm can control corrosion better than they are doing. Someone is going to be hurt or killed due to these vehicles rusting so badly.
Tl* the contact owns a 1999 gmc sierra. While driving approximately 35 MPH on a four lane highway, the contact came to an abrupt stop and the brake pedal suddenly traveled to the floor without resistance. The vehicle was towed to an independent mechanic where the technician informed that the brake line quality was poor with inexpensive materials. The vehicle was repaired at the cost of $850. In addition, the fuel lines exhibited leakage due to excessive corrosion which was replaced on a separate occasion. The manufacturer was notified and they stated that there were no complaints filed on the brake line system. The failure mileage was approximately 60,200. The VIN was unavailable. Updated 06/16/11*lj the consumer also stated there was a problem with the fuel lines. Updated 06/21/11
Fuel pump/sending unit faulty. Gauge does not read proper fuel levels. One minute while going down road you have a full tank next minute light comes on fuel gauge reads empty. Sometimes gauge will not read fuel in tank at all. I have come across other gmc owners who have the same complaint. Guys at shop say it is common to replace the fuel pump/sending unit.
The fuel gauge on my 1999 gmc sierra ext. Cab does not work. It has never worked. I did not see the problem as urgent until my brother-in-law, who has the exact same truck, got stranded in mexico because his fuel pump went out. He has had the same problem since he has had his truck and it cost him $300.00 dollars to change the fuel pump out. That was cheap because he did the work himself. I have done some research on the internet and have seen the same problem with several trucks of the same model and year. I went to the local dealership and there is no recall on the fuel pump for my truck and would respectfully request that the fuel gauge/pump for the 1999 gmc/chevy 1500 truck be looked into for consideration for a recall.
Dt*: 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.
My gas gauge on my 1999 gmc sierra has not worked for over two years. Cost of repair to high.
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. *nm
Fuel gauge low fuel light comes on intermittently even after just filling up and fuel gauge bounces all over the place.
