Why This TSB Matters

Technical Service Bulletin (TSB) 09-024-25, issued on August 19, 2025, provides crucial information for diagnosing and repairing engine oil leaks in certain 2024-2026 Jeep Compass and Renegade vehicles. This bulletin specifically addresses issues related to the Jeep rear main crankshaft oil seal leak, which can manifest as visible oil leaks or trigger dashboard warning lights. This TSB supersedes a previous bulletin, 09-019-24, dated September 05, 2024, incorporating updated vehicle information and repair procedures.

Symptoms of a Rear Main Crankshaft Oil Seal Leak

Owners of affected Jeep vehicles may observe one or both of the following symptoms:

• "Oil Pressure warning light illuminates."
• Engine oil leak.

These indicators suggest a potential problem with the rear main crankshaft oil seal, requiring inspection and possible replacement.

Root Cause

The underlying cause for these symptoms is identified as a faulty rear main crankshaft oil seal. This seal is critical for preventing engine oil from leaking out where the crankshaft exits the engine block.

Important Information for Owners

This TSB has also been released as Rapid Service Update (RSU) 25-171, dated August 19, 2025. To determine if your specific vehicle is covered by this service action, it is recommended to verify your VIN through VIP or a VIN search in DealerCONNECT/Service Library.
