Known to GM injector problems with Chevy Silverado vehicles. My injector cracked or failed and diesel went in to my engine oil, causing an over fill of 2 gallons. Oil was leaking out all over from my truck while I was driving. There are many other post about this problem and GM is aware but hasn't issued a recall.

The glow plugs and fuel injectors fail prematurely I was told by the locol servace manager that there was plenty of time to get the repairs but a few weeks later when I brought it in for the supposed free repairs they tell me the time for mine is over its too old. When no one had showed me a print out and the company I bout it from never disclosed the issue. If the vehicle stalls in traffic it could cause an accident.

While driving on the highway, the truck, for an unknown reason, shut down causing me to loose power steering and brake capability. I was able to shift into neutral and turn the key off and then back on again to re-start the truck. It has now happened several times and I have done the same thing each time to correct the problem. It happened once in 2009 and twice in 2010. Since then it has happened a few times per year at random times. GM has told me in the past that they don't know what would cause that issue. I could not get my local Chevrolet shop manager to give me a straight yes or no answer regarding whether my problem is consistent with the issues being experienced by effected GM models with ignition problems. I believe it may be due to the recalled ignition switches as I have had the electrical system looked at and no one can seem to find an issue that would cause the truck to shut off randomly at highway speeds and then turn right back over after shifting to neutral!! I believe that the current recall does not cover all of the vehicles that are truly affected. I have had my family in the truck on several occasions when this has happened and have been fortunate to not have had an accident to this point.

Engine stalls occasionally while driving, and put me in a dangerous situation. Fortunately I live in a small town has little freeways. Also the driver side seatbelt is stuck and I can not pull it out.

The truck was hooked to a 25' gooseneck trailer loaded with hay. The engine was the duramax diesel with allison transmission. The intent was to haul hay from eastern Washington to western Washington. The power steering pump broke a shaft inside the pump making the power steering unusable. As it turns out the power steering pump also serves as the power brake assist. At a speed of about 3 mph, it was all I could do to brake the truck but was unable to turn the wheels. It was very fortunate that this happened in the farmers field and not on the highway. If I had been driving on the highway when the pump quit working, the truck would have gone off of the roadway, most likely over a steep cliff because I would have been unable to steer the truck or stop it due to the single pump failure. Additionally, the load of hay would have caused the truck to pick up speed if it was going down hill.

The contact owns a 2002 Chevrolet Silverado. The contact stated that while driving, the engine began making a clicking noise. The contact noticed that one exhaust manifold bolt was broken. The vehicle was taken to a local mechanic who advised that two exhaust manifold bolts were fractured. The contact stated that if the vehicle continued to be driven, the catalytic converter would be damaged. The failure recurred because the bolts were defective. The manufacturer was not made aware of the failure. The current and failure mileage was 69,000.
