problem #1

Feb 232017

Sierra 1500 4.3L V6

  • Automatic transmission
  • 42,875 miles

Oil pump totally failed. Caused engine to also fail. Thank goodness the vehicle still had the power train warranty. Always had GM change the oil and the truck has been well looked after. Shame on GM for producing an oil pump that is faulty. Mission critical that the oil pump needs to work.
