Problem: Corroding Tailgate Cables
Units Recalled: 4 million
In 2004, GM recalled nearly 4 million pickups and SUVs because of corroding tailgate cables. The galvanized steel support cables would weaken and eventually fracture on certain Silverados, Sierras and Escalades, causing the tailgate to suddenly drop and strike the rear bumper.
