This Mopar Warranty Operations Newsletter, Volume 11, Issue 4, dated April 9, 2025, provides crucial updates for technicians and owners of various 2021-2025 Mopar vehicles. It covers a range of topics from warranty exclusions and core return policies to specific diagnostic and repair procedures for common issues, including 2024-2025 Mopar Intelligent Battery Sensor diagnostics, coolant leaks, and power seat malfunctions.
Recall Order Type Updates
Mopar is improving its Exchange Order Process by adding a specific "Recall" order type. Currently, recall exchange parts are ordered as "Warranty." This change will align the order type with the claim type, streamlining the process. The exact implementation date will be announced later, and it will not affect claim requirements or chargeback procedures.
High Voltage Lithium-Ion Battery Exclusions
Owners of vehicles with High Voltage batteries should be aware of specific conditions that can void their warranty coverage. Your warranties do not cover the costs of repairing damage or conditions caused by any of the following:
- Physical damage or intentional attempts to reduce the battery's life.
- Leaving the vehicle for over 30 days with the high voltage lithium-ion battery at a zero or near-zero state of charge.
- Neglecting to follow recommended charging procedures as outlined in your Owner's Manual.
- Using incompatible charging devices.
- Opening the high voltage lithium-ion battery enclosure or having it serviced by unauthorized personnel.
- Exposing the high voltage lithium-ion battery to direct flame or ambient temperatures above 140°F (60°C) for over 24 hours.
HV Pack Core Refund Policy
Dealers must strictly adhere to the directions in the I-Sheets for returning HV pack cores. Failure to follow these procedures means dealers potentially WILL NOT be issued a core refund. Incorrect returns cause logistical issues and unnecessary expenses. An example of the I-Sheet can be found under DCMail ID: 104553.
Vehicle Maintenance: Engine Oil Filter
It is essential to replace the engine oil filter with a new one during every engine oil change. For replacement, a full-flow type disposable oil filter should be used. Mopar recommends using high-quality Mopar® filters. If Mopar® filters are unavailable, bproauto filters are the preferred alternative. If neither is available, only use filters that meet or exceed SAE/USCAR-36 Filter Performance Requirements.
Side Marker Condensation in 2024 Fiat 500e (FG)
Condensation may appear inside the side markers of the 2024 Fiat 500e (part numbers 68656439A and 68656440A) under certain atmospheric conditions. This is considered normal and will dissipate over time. The side marker is a decorative, non-functional part, and condensation does not pose a risk to the vehicle's performance or safety. Therefore, this condition is not covered under warranty.
Coolant Leak & Engine Overheating Issue (2021-2025 Jeep/Dodge/Alfa Romeo)
For 2021-2025 Jeep Wrangler (JL), Jeep Grand Cherokee (WL), Jeep Compass (MP), Dodge Hornet (GG), and Alfa Romeo Tonale (GC) vehicles equipped with the GME T4 DOHC engine experiencing coolant leaks and overheating, engineering recommends using a long block for repair instead of a complete engine replacement to reduce costs.
Diagnosis / Trigger Conditions
Before replacing a long block, technicians should perform the following pre-checks and checks:
Pre-Checks:
- Check and record the coolant level in the coolant bottle.
- Inspect for thermostat and other cooling system issues (e.g., water pump, cooling fan).
- Drain an oil sample to check for coolant or moisture presence.
Checks:
- Perform a Cylinder Leakage Test on all cylinders, pressurizing one cylinder at a time with the piston at TDC using 5.5 bar of air, and check for bubbles in the radiator coolant.
- Conduct a coolant pressurization test on the cooling system (pressurize to 2 bar / 30 PSI) and borescope cylinders for coolant presence in the combustion chamber. Hold pressure for 1 hour and check for leak down.
- Perform cooling system leak inspections available in the Service Library, including internal engine leakage inspection.
- Perform a CO2 leak test to check for combustion gases in the cooling system.
If none of these checks indicate a problem, a long block or complete engine replacement is not necessary. Instead, focus on identifying the specific component causing the coolant leak. Common culprits include:
- Water pump inlet pipe bolts losing torque.
- Water pump gasket twisted inside its groove.
- Thermostat column manifold losing torque or bolts.
- Cylinder block casting porosity or cracks versus the combustion chamber.
- Oil coolant exchanger internal crack (evidenced by coolant and oil mixing).
Other indicators of an issue include a low coolant level in the reservoir, the vehicle not starting, power/torque degradation, high misfire events, and the check engine light illuminating.
