2001 GMC Sierra 2500 Owner Comments

problem #3

Mar 102018

Sierra 2500

  • 200,000 miles


The contact owns a 2001 GMC Sierra 2500. While driving various speeds, the engine suddenly lost compression and the vehicle failed to accelerate properly. The vehicle was taken to courtesy Cadillac (1345 evangeline thruway, broussard, la) where it was diagnosed that one or more fuel injectors were faulty and remained open. The vehicle was not repaired. The manufacturer was notified and did not assist. The contact indicated that all eight fuel injectors were previously replaced approximately five years; however, but the failure recently recurred. The failure mileage was 200,000.

problem #2

Sierra 2500 4WD 8-cyl

  • 130,000 miles
Exhaust manifold leak due to broken exhaust manifold bolt. I am the original owner of the vehicle. The vehicle has been regularly and properly maintained. I understand this is a common problem for this GM vehicle due to defective parts. I purchased this vehicle new from a local GMC dealer.

problem #1

Oct 082013

Sierra 2500 4WD 8-cyl

  • 70,300 miles
Engine stalled after pulling out onto highway then restarted, engine stalled at stop light restarted 5 minutes later, engine stalled immediately after starting then started two minutes later. GM recall #06083 crankshaft position sensor from Dec. 11, 2007 needs to be expanded to include more or maybe all 2001S with 8.1L V8 not just the VIN # that are listed.
