Engine Knocking Noise Problems of GMC Sierra 1500

The contact owns a 2010 GMC Sierra 1500. While driving approximately 55 mph, the traction control and stabilizer warning indicators illuminated. The engine made a knocking noise and the vehicle failed to accelerate at the desired rpms when the accelerator pedal was depressed. The contact took the vehicle to jim faulk motors (1201 n 2nd st clinton, mo 64735; 660-956-0076 or 877-819-4482) where it was diagnosed that the engine failed and needed to be replaced. The vehicle was repaired, but the failure recurred. The contact returned the vehicle to the same dealer where it was diagnosed that the engine failed and needed to be replaced again. The vehicle was not repaired. The manufacturer was made aware of the failures and stated that, due to the warranty expiring, they were unable to assist with the repair. The approximate failure mileage was 178,000.

I own a 2004 GMC Sierra 1500 that is currently being repaired for cracks in both engine heads. The truck has 90,000 miles on it and I have kept up on all necessary maintenance. The problem began approx. 2 months ago when I noted a knocking sound after starting the truck cold. The knocking would dissipate after the truck warmed up. I was told the sound was caused from dirty lifters and not to be concerned as long as sound dissipated after it was warm. Upon having my oil changed 2 days ago, coolant was noted in the oil. (hints the knocking) the heads were pulled and both were cracked around where the heads bolt to the block. In talking to the mechanic, the cast they used when making the heads was bad. Apparently around the bolt holes, the aluminum is thin. GMC however accepted millions of these and are still using them today. The repair is costing me $3,400. 00.
