Consumer Description

To whom this may concern, This gmc truck with the 6.2 has had constant engine issues regarding the lifters failure causing the engine to destroy itself internally I’ve had to get it repaired every 3 Months on average there’s also a class action lawsuit that applies only to the 2025-2020 years however they are the exact same engine in the 2017. The transmission is not in sync with the motor having a late take off or sounds like the gears are grinding between shifting
