2021-2026 Stellantis Engine Oil Leak TSB S2509000009

Symptoms of an Engine Oil Leak

Owners of 2021-2026 Stellantis vehicles, including the 2024 Jeep Wrangler, may notice several signs indicating an engine oil leak. Common complaints include a 'Low Oil Lamp-on' warning light illuminating on the dashboard. Additionally, drivers might observe 'oil leaking on the ground under the vehicle', suggesting a visible external leak.

Diagnosis and Source of the Leak

Diagnosing the source of an engine oil leak typically involves following established procedures in the Service Library, often utilizing Leak Detection Dye to pinpoint the exact origin. Technicians are advised to carefully inspect the transmission bellhousing-to-engine interface. It's crucial to confirm that the leak is not originating from areas above this interface, such as the back of the intake manifold or valve covers.

If the leak is identified as coming from the main oil gallery rear plug located above the crankshaft, a specific repair is recommended. This plug is a known potential source for oil leaks in affected vehicles.
