Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Silverado 2500 8-cyl Diesel

I was entering my driveway and began to brake going downhill, the brake pedal sudden "went to the floor" (brake line had ruptured due to corrosion). After taking truck to mechanic, I learned all my brake lines were serverely corroded and had to be replaced - fuel lines as well. Repairs totaled $2185. I owned several other make pickups, driven under the same conditions and have never experienced any problem with either brake or fuel lines.

The truck has 110K miles on the duramax / allison drive train. The diesel fuel injection pump failed unexpectedly and without warning. This powertrain combination should be capable of 500K miles without problems like this. This pump should not fail after normal use in only 110K miles. Nothing but excuses and other not possible reasons for the poor engineering and manufacturing exhibited in their product. They said the methanol water injection system caused the fuel injection pump to fail. Methanol (non caustic fluid) is injected air side of the engine and does not mix with the injected fuel until the engine cylinder. The fuel injection pump supplies fuel to the individual injectors that then in turn supplies the high pressure fuel to the cylinders. If this condition was to happen on the road pulling a trailer / heavy load in hills or other confined roadways people could be injured or killed by the sudden loss of power and control. GM business practices are going to continue to kill and hurt people.

Fuel lines corroded and rusted though and leaking, potential for vehicle to catch fire. Brake lines severe rust and corrosion. Can fail at anytime potentially causing vehicle crash, I have a 1996 Chevrolet cavalier with over 200,000 miles and the brake and fuel lines on this car are in better condition than this truck.

On January 23, 2009, the #7 injector harness shorted and had to be replaced. On March 21, 2009, the ses light came on and the truck sounded different running, but did not lose power. Diagnostics showed problems with the fuel injector module. On March 22, 2009, the ses light came on and the truck started running rough and lost engine power (just like it did on January 23). The truck had to be towed to the Chevrolet dealership again. This time the #2 fuel injector harness had shorted and had to be replaced. With both incidents, the fuel injector harnesses were replaced with a new harness that has a 90 degree plug and longer wires. This is not covered by warranty and costs $400+ to replace each one. Within 2 months and 2500 miles both the #2 and #7 fuel injector harnesses have shorted and had to be replaced.

When I was driving down interstate the truck (2005 2500 hd diesel) suddenly started running rough and lost engine power. The ses light came on. I pulled to the shoulder and turned the truck off. When I restarted the truck the ses light stayed on, but the truck would run. It went about 2 more miles and did the same thing again. It had to be towed to the Chevrolet dealership. The #7 injector harness had shorted and had to be replaced.

Towing trailer on the I90 interstate. Sudden loss of power and unable to regain speed on high speed highway. Dealer diagnosed as "fuel filter" problem. Has happened on numerous occasions seems common problem with GM duramax diesels from 2003 to present. The sudden loss of power can be dangerous on high speed highways as speed is cut drastically and speed cannot be regained to make a safe pull over to the side of the road.

During a routine morning commute, I noticed the check engine light had illuminated. Immediately following the malfunction, I noticed a severe decrease in engine power and the engine started to vibrate and mis-fire heavily. I was in heavy traffic and had to pull off of the road to avoid a potential accident situation. I then shut the truck off, and re-started the vehicle to possibly re-set the light. The engine started and seemed to run smoothly again, but the light stayed illuminated. It was 7am, so I decided to very slowly drive to the dealership where I had purchased the truck. The technician performed a diagnosis, and found a hard code of P2146 insulate ficm. I was then told that the main fuel injector system wiring harness had chaffed on a factory installed bracket and that it would need to be replaced. I was then told that they did not have the parts in stock, and that I would have to wait for one week to have the parts replaced. In the meantime, the technician stated that he had "insulated" the harness, and that the light was out. He stated that I should be able to drive the truck without any issues, but if the check engine light comes on again and I also receive a "low power" message on the annunciator panel in the dashboard, that I must park the truck and get a rental vehicle until the parts arrive and repairs can be made. The technician stated that this would cause four of the eight cylinders to shut down and cause a lean engine fuel condition which could result in engine failure. As of yet, parts to be replaced within one weeks time.

Driving 50 mph on road, I stepped on the accelerator pedal to accelerate and the vehicle engine light came on. However the vehicle would not accelerate it was spitting and sputtering and slowed down for a while. I pulled over to the side of the road and shut it off. After ten minutes, the vehicle was restarted, and light went out and it ran perfectly.

: the contact stated the vehicle stalls at any speed without warning. The vehicle was taken to the dealership several times. The level sensor, fuel injection wiring harness, the direct fuel injection driver, the fuel tank, and the fuel tank module have been replaced. The sender pump assembly was replaced twice. After the last replacement the check engine light illuminated and the dealer could not determine the cause of the problem.

Vehicle diesel system has a problem transferring fuel into the truck for use. It runs out while the front fuel tank is still full of fuel. The fuel tank never reads over half full. It is being towed for the second time during the month of July. It will be in the dealership shop for the 3rd time since purchased, 2nd time this month. We are told they do not know what to do, since they cannot figure out the problem. We are currently waiting for a service bulletin. This truck is our only work truck and a car loaner does not help with the towing of our MINI

It started with fuel guage failure severel times. I was told to bring the truck by and they would reset the computer until a bullitin from the manufacturer came out. The truck broke down away from home then they had a bullitin and made the repairs. Truck breaks down again Kansas service manager said they had lots of problems with this fuel system. Truck has new transfer pump installed then gets picked up, five miles later fuel guage fails once again.
