General Motors (GM) has faced numerous legal challenges related to alleged defects in its engine injection systems, specifically the CP4 fuel injection pump used in certain diesel trucks. These defects allegedly caused catastrophic engine failures, leading to costly repairs for vehicle owners. In response, GM agreed to a series of class action settlements, involving substantial monetary funds and extended warranties. This article offers a comprehensive examination of the General Motors injection system settlement, covering background, settlement terms, eligibility, legal framework, payout details, current status, claims process, and future outlook.
Background of the GM Injection System Defect and Settlement
The GM injection system settlement stems primarily from claims regarding the Bosch CP4 high-pressure fuel injection pump installed in certain GM diesel trucks equipped with Duramax 6.6L V8 LML engines manufactured between 2011 and 2016.

- Class members consisted of owners and lessees who bore the repair costs or suffered diminished vehicle value due to the defect.
- GM did not admit wrongdoing but agreed to a settlement to avoid the expenses and risks of protracted litigation.
