Example complaints
Electrical system: “Vehicle was last driven on June 23 2024 and parked in my driveway. On the evening of June 29 2024 my horn was blowing in my truck at around 10:30.

NHTSA complaint #11597612, filed 2024-06Engine: “Recall was issued april 25 2019, as of today almost 1 year later GM is still saying I can't get it done. Yet they are building and selling vehicles with updated parts in them.”
NHTSA complaint #11319351, filed 2020-03, 12,000 milesFuel system: “The contact owns a 2019 GMC Sierra 2500.

NHTSA complaint #11619152, filed 2024-10, 33,000 milesBrakes: “I purchased a 2019 GMC Certified 2500 Diesel Truck with 48000 miles I started getting alerts on my dash stating TRAILER BRAKE SYSTEM over and over. I would press the dismiss button but it would not stop from appearing and dinging over and over. I took vehicle to dealer ship since I have remaining bumper to bumper and extended warranty coverage.
