The Problem: In vehicles without power seats, the manual seat recline function might fail to meet a safety requirement for a rear-end impact. This could allow the seatback to move in a crash, compromising the safety of passengers. However, the company has no reports of injuries caused by this problem.
The Fix: Dealers will inspect the seatbacks and make any necessary changes at no charge to owners.GM notes that most of these trucks are still at dealerships, meaning that dealers will inspect and correct the error on these unsold models.
