2021 Chevrolet Silverado 1500 body problems

According to 2 mechanics- including a body shop - the frame has prematurely rusted due to: TSB 19-NA-255 - Wax Coating on Frame Peeling, Metal Shows Corrosion/Rusting There's so much damage to a 2021 truck, that it may not survive this winter. The frame welds are breaking due to the lack of frame protection. I asked my dealership, Lamoille Valley Chevrolet 868 VT RT 15E HYDE PARK, VT 05655, on two separate occasions to check for damage. One time they made no report, the second time they told me it was normal wear and tear. I've been told trucks 20 years older than mine, are in better condition. There was no protection for this frame.

Statement for the federal safety agency Subject: Safety Complaint – 2021 Chevrolet Silverado Unexpected Jerking/Harsh Transmission Engagement I am submitting this complaint regarding my 2021 Chevrolet Silverado 1500 2.7L Turbo with approximately 128,000 miles. My vehicle has developed a recurring problem involving harsh/jerking transmission engagement, hesitation, shuddering and abnormal shifting. The truck can jerk when engaging or changing gears and has also experienced a hard engagement when shifting from Reverse into Drive. During normal driving, the vehicle can hesitate or feel as though it is repeatedly fluttering/shifting instead of providing smooth and predictable acceleration. The vehicle has produced diagnostic trouble codes including P0700, U0100 and P0420. I am concerned that this condition could create a safety hazard, particularly if the vehicle unexpectedly jerks, hesitates or fails to respond normally when accelerating or changing gears in traffic. I am requesting that the federal safety agency document this complaint and review whether there is a pattern or potential safety-related defect involving transmission engagement, shifting or drivetrain control on 2021 Chevrolet Silverado vehicles. GM has published service information concerning delayed and harsh transmission engagement on certain Silverado applications, including 2019–2021 models, which makes me concerned that my vehicle may be experiencing a related issue. I am retaining my repair records, diagnostic information, receipts, videos and mileage/date information documenting when the problem occurs. I am willing to provide this information if requested. Please help me get my truck corrected, I love my Chevy Truck. Thanks Sincerely [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Rear tailgate does not open and sometimes will show a warning on the dash that the tailgate is open when it is not. The tailgate for the heavy duty 2500/3500 trucks were recalled for the same reason but not the 1500 trucks. This is a common issue on the truck forums and is an unsafe condition.

When it rains. Tailgate opens on it own. Either have to lock truck or quickly put into drive to prevent tailgate from opening on its own. Only in wet weather. Tailgate opened on its own in rainy weather when parked at hardware store. I began to drive away not knowing tailgate opened and lost tool box and material out the back while making a turn. Speaking with GM I was explained it’s a known issue on 2500 models but not for 1500 models.
