NHTSA Complaint #11701898 — 2022 JEEP GRAND CHEROKEE

Timing cover leak, replaced by dealer once covered under warranty. Few months later same leak occurred in the same park after dealer replacement. Back to the dealer to have checked, dealer found that the head gasket during manufacture/casting has defect causing the head gasket to protrude into the mounting surface for the timing cover gasket/seal causing improper seal and securement. Dealer got Jeep engineers involved and found it was during manufacture and assembly/casting process. New head gasket being replaced and installed inspection of all mounting surfaces on cylinders valves and pistons for additional damage, and replacing timing cover gasket again. This caused loss of engine oil over time even after dealer fix and replacement the first time, this could cause drivers to not know they are low on engine oil causing potential catastrophic engine damage or failure/seizing during normal operating conditions. This is a common failure in the Jeep 4xe of timing cover seal issues and leaks.
