“Around 40,000 miles the engine began ticking and tapping after start-up when the rngine is cold. Now its happening all the time when you start it up. I heard from other owners its called (piston slap). I took ithe vehicle to the dealer and they said they had quite a few complaints about this and said the manufacture is working on the problem. Does'nt look like anything will be done about it!!!! Please help?”
NHTSA complaint #10119891, filed 2005-05, 40,000 miles“The gas pedal sticks. I have to clean my throttle body out with cleaner about every 1000 miles. Even after a cleaning it still sticks a little. This is a safety concern, because I have to use more pressure on the gas pedel, then it unsticks and the truck lurches foword with no control.”
NHTSA complaint #10045742, filed 2003-11, 70,000 miles“I have a 1999 chevy Silverado that has been diagnosed with piston slap. This all started shortly after I purchased the vehicle in 1999. However, the dealer refused to fix it, stating that it is normal noise. (normal? Then why didn't the engine make this noise when I first drove it off the lot)? I continued asking the dealer about the noise but they continued to say that it was normal noise. Finally, I took the vehicle to another GM dealer on april, 2004. The vehicle had 48,799 miles. …”
NHTSA complaint #10125985, filed 2005-06, 5,000 miles“I have a loud ticing noise coming from the left rear of the engine. While I was pulling my 5th wheel the noise kept getting louder and louder and had loss of power. By the time we got to the camp ground it sounded like I had lost my mufler. We took it to muffler man of ludington and they discovered that 4 exhaust manifold bolts had sheared off, 2 on left year and 2 on right rear of both manifolds. They took the manifolds off and replaced all the bolts with new ones except for the very left rear was sheared off flush and could not get a drill in to drill out and tap. …”
NHTSA complaint #10090664, filed 2004-09, 50,000 miles“The head gasket on the motor leaks antifreeze. This has been noted several times on vehicles that use the extended life antifreeze. The cost to fix the problem is not cheap due to the cost of labor required to remove the head from the motor and replace with new seal.”
