2005 Chevrolet Suburban Owner Comments

problem #3

Dec 102008


  • 73,000 miles


My 2005 K1500 Suburban sustained a cracked head with 73,000 on the engine. The service department at my dealership has no information that a manufacturing problem exists. The repair cost over $2,000. This is not a normal occurrence or expected vehicle wear.

The contact owns a 2005 Chevrolet Suburban. While driving 35 mph, the contact released the accelerator pedal and the RPM's decreased to 1,000. When the accelerator pedal was depressed, the vehicle would clunk forward. The vehicle has been diagnosed by the dealer, but the failure remains. The current mileage was 13,000 and failure mileage was 11,638.

Suburban 4WD 8-cyl

  • Automatic transmission
  • 18,000 miles
This is a pre-cautionary complaint as a result of my shock regarding GM's 8.1L engine in the Suburban. Also would apply to Silverado hd as well. The vehicle is using excessive oil which to my surprise GM says is normal. Oil usage is 1.25 qts per 2000 miles and GM indicated that the vehicle could use as much as 1qt per 1000 miles (assuming 10 miles to the gallon). The concern is regarding emissions durability and indirect failures as a result of this oil loading into the exhaust and catalytic converter. GM would not provide details to me but, industry norms are assuming worst case 1/2 of this level of expected oil usage. GM was unconcerned and has a bulletin for their dealers stating this. I feel this should be investigated both from a safety standpoint for potential engine failure and for emissions durability and environmental compliance.
