problem #1

Nov 072018

Silverado 1500 LTZ 5.3L

  • Automatic transmission
  • 5,717 miles

Engine gets severely diluted with water and fuel. Dealer has had it to flush engine 3 times and put cardboard in grill. Told me I don't drive it enough. Complained to GM Canada and dealer is replacing high pressure fuel pump, doesn't explain water contamination. Did oil analysis on my own and it clearly showed engine damage. They said unless it has fillings in oil, they don't worry.........OMG dealership are idiots. Unreal terrible trouble shooting. Issues may actually be resolved as truck fuel pump is on back order for 2 weeks.
