Sierra 3500

  • 35,900 miles
The GMC Sierra 3500hd while in regeneration mode funnels exhaust directly into the cab through the vents. While GM recognized this as a flaw and came up with a fix for it, they will only repair it in a 5 year or 100,000 mile window. How is this not a safety issue without an expiration?
