2021-2024 Jeep Wrangler/Gladiator Water Leak TSB

Owners of 2021-2024 Jeep Wrangler and Gladiator vehicles may encounter an issue where water leaks into the cabin, specifically near the front bulkhead or cowl area on the driver's side. This problem, identified in Mopar STAR Online Publication TSB S2423000029, can lead to noticeable dampness or wetness on the driver's side floor and carpet. Addressing this Jeep Wrangler water leak promptly is important to prevent further damage.

Technical Service Bulletins (TSBs) are communications from vehicle manufacturers that provide recommended procedures for repairing common problems that may not be significant enough to warrant a full safety recall. TSB S2423000029 outlines a specific diagnostic and repair procedure for this water ingress issue.

Symptoms of a Water Leak

The primary symptom reported by owners and technicians is: "Customer notices water on the floor, carpet wet on driver's side." This indicates that water is entering the vehicle's interior. Beyond the immediate inconvenience, persistent moisture can lead to several problems, including unpleasant odors, mold growth, and potential damage to electrical components located beneath the carpet or dashboard.

Diagnosis of the Water Leak

To diagnose the Jeep Wrangler water leak, technicians are instructed to inspect the front bulkhead for any opening that is not properly covered by a plug or tape. The TSB includes a figure illustrating the specific location to check, which is visible from the engine compartment side. This opening, if left uncovered, allows water to penetrate the passenger compartment.

Repair Procedure Summary

The repair for this water leak is straightforward. If an uncovered hole is found in the front bulkhead during the inspection, a specific plug, part number 68185743AA, needs to be installed. The TSB specifies that the plug should be inserted from the engine compartment side. After the plug is installed, a water test should be performed on the vehicle to confirm that the condition is fully resolved and no further water ingress occurs.

Important Warnings

It is crucial for owners to note that TSB S2423000029 explicitly states: "This document does not authorize warranty repairs." This means that while the bulletin provides a solution for the Jeep Wrangler water leak, the cost of diagnosis and repair may not automatically be covered under warranty. Owners should discuss potential costs and warranty coverage with their dealership before proceeding with any repairs.

What Owners Should Do

If you own a 2021-2024 Jeep Wrangler or Gladiator and are experiencing water on the driver's side floor or wet carpets, it is recommended to contact your authorized Jeep dealership. Explain the symptoms you are observing and mention TSB S2423000029. The dealership can perform the necessary inspection to determine if a missing bulkhead plug is the cause of your Jeep Wrangler water leak and advise on the appropriate repair.
