2005 Chevrolet Silverado: sudden loss of power

Filed Jun 20, 2014 · Fuel system · 110,000 miles · WA

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.

Truck has 14000 miles, it has constant over heating problems while towing my 8k travel trailer. I have talked with the chevrolet dealer about it, they told me that they were aware of the problem but at this time have no fix. I call stupid because I heard online that the 06 models have revised cooling systems and a larger turbo charger. My belief is the fix is to much $$ and they will only take care of the few people that tow and have issues. I have notice a lot of information on the net about 04.5 and 05 lly duramax truck that tow over 10000 have this issue but my travel trailer fully loaded only weighs under 9k. The major down side is the trucks inability to maintain the speed limit due to the overheating water temperature and the power loss formed a cooling fan that runs hyperspeeds no stop when towing. My towing has been done at low outside temperatures ranging for 75 to 85 degrees outside. This truck is not performing as advertised or supposed to be designed for.

Gm technician line has a case # on file, and told the technician who relayed the information to myself that they were aware of the problem but at this time have no fix. I call bs because the 06 models have revised cooling systems and a larger turbo charger. My belief is the fix is to much $$ and they will only take care of the few people that tow and have issues. I have notice a lot of information on the net about 04.5 and 05 lly duramax truck that tow over 10000 have this issue. The major down side is the trucks inability to maintain the speed limit due to the 234* plus water temperature and the power loss formed a cooling fan that runs no stop when towing. I have made the same pull with my 2001 chevrolet duramax truck and have not had issues with impeding traffic flow.
