If your 2020 or newer Chevrolet Silverado or GMC Sierra 1500, 2500, or 3500 had its tailgate randomly open when you didn’t want it to, we’ve got some good news and a solution.

The Problem – Tailgate Opening Issue

Reports have skyrocketed online, with owners of Silverado and Sierra pickups reporting that the tailgate of their trucks are opening randomly and without them wanting it to.

The issue is detailed in Technical Service Bulletin 23-NA-112 and provides dealership service technicians with two new part numbers they can use to fix the situation.

Using reports from owners who have experienced the issue- water intrusion is expected to be the culprit- causing unintended tailgate latch button engagement. If a trailer is attached or the truck is parked close to a hard surface( a garage door, wall, or building), damage may occur if the tailgate unintentionally opens.
