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. I asked the mechanic and service representative to listen to the engine, both determined the noise was not normal, and needed repaired. They performed numerous engine repairs that seemed, at that time, to make the noise go away. In June, 2004, the vehicle now had 49,023 miles, the noise had returned, and the GM dealer again stated the noise was not normal. They then replaced the long block of the engine, that seemed to have taken care of the problem. As of this date, the vehicle is back at the GM dealership with the same engine noise, which is a loud ticking/knocking noise. I am, again, being told is "normal" for this engine. (this is statement is being quoted by General Motors, as being "normal". initially, when I recently took the vehicle to the GM dealership, the service technicians indicated the noise was not normal...until the engineers at General Motors conveyed the noise as being "normal".)

Consumer stated that after 12,000 miles the engine was having a knocking sound. Consumer took vehicle to the dealer, and was told that there was no solution for the vehicle, and the manufacturer was exploring ways to remedy the defect.

The transmission was serviced more than four times while under warranty for the vehicle revving and sticking in gear. The vehicle has been maintained as it should have been. The manufacture offered no help. The engine had come on, the fuel gauge did not read correctly, transmission slipped, the C control would not engage and a green and white wire at the pin circuit was loose, and the sensor in the washer jug was bad.

This is the first new vehicle we have ever bought. But not a good expreience, we have always had GM products with no problems. We just had the truck in the garage and they put it on the computer, it said code PO137 02 sensor bank 1 sensor 2 replace also code PO300 misfire #7 cylinder replace injector and fuel pressure regulator. This cost $448.78. Also PO300 misfire #7 cylinder replace injector and fuel pressure regulator and code PO463 fuel level sensor needs fuel sensor replaced at a cost of $301. We can't afford this at this time. They also said both front wheel bearings with speed sensors need replaced at a cost of $642. We can't have this done now either. We are going to try to get along with the brake failure long enough to save money to fix. We replaced the battery Sept 11th at a cost of $65 and an alighment in June at a cost of $47 and rear brake rotors and pads replaced in July at a cost of $279. We had thought of trading or selling outright and getting another truck, but can't sell it as it is.

Computerized engine design does not include monitoring engine coolant temperature for appropriate cyclic function and indicating proper thermostat protection, poor performance. Mjs
