problem #1

Sierra 1500 Denali 6.2L

  • Automatic transmission
  • 22,400 miles

A D V E R T I S E M E N T S

2020 GMC Sierra Denali CarbonPro; 22400 miles; always in garage; never pressure washed; only hand washed; just like service bulletin 18-NA-383; water leaking at rear sliding window due to cracked rail; must be a design or manufacturing defect; I have owned only GM products for 40+ years; after all that loyalty on my part, you might think they would help out with costs; but no, this is routine according to them.
