Is your Jeep Grand Cherokee blowing hot air instead of the cool relief you expected? You’re dealing with something that might be more than just a typical AC issue. Thousands of Grand Cherokee owners have faced air conditioning problems that are actually related to official manufacturer actions. Let’s cut through the confusion and get you the facts about the Jeep Grand Cherokee air conditioning recall situations, what models are affected, and exactly what you can do about it.
The Main Air Conditioning Issues Affecting Jeep Grand Cherokees
Stellantis (formerly Fiat Chrysler Automobiles) has taken several actions to address air conditioning problems in Jeep Grand Cherokee vehicles. While there isn’t one single “universal” air conditioning recall, there are multiple significant notifications that collectively impact tens of thousands of vehicles.
Customer Satisfaction Notification Z33: What You Should Know
In March 2022, Stellantis issued Customer Satisfaction Notification Z33 specifically addressing air conditioning failures in certain Grand Cherokee models. This notification covers approximately 7,903 vehicles from the 2021-2022 model years with the WL designation.
The root cause? A software defect in the Heating Ventilation Air Conditioning (HVAC) module that prevents the air conditioning compressor from working properly. If you’re experiencing any of these symptoms, your vehicle might be affected:
- Reduced cooling performance
- Inconsistent or choppy airflow
- Strange odors coming from the vents
- AC blowing only hot air
Stellantis classified this as a “Customer Satisfaction Notification” rather than a formal safety recall because they considered it a comfort issue rather than a safety hazard. However, they’re still providing free repairs to all affected vehicles.
The fix involves reprogramming the HVAC module with updated software, which typically takes about 30 minutes at the dealership. The repair requires specific diagnostic equipment, including the wiTECH MicroPod II diagnostic tool and specialized software.
Safety Recall 24V-111: Defrosting System Issues
If you own a 2022-2024 Jeep Grand Cherokee Plug-in Hybrid Electric Vehicle (PHEV), pay close attention. In February 2024, Safety Recall 24V-111 was issued affecting 59,825 Grand Cherokee PHEV models.
This recall addresses a software error in the hybrid control processor (HCP) that can disable the windshield defrosting and defogging system. Unlike the Z33 notification, this was classified as a safety recall because it violates Federal Motor Vehicle Safety Standard No. 103, which requires all vehicles to have functional defrosting systems.
The safety risk here is significant—a disabled defrost system can drastically reduce visibility during certain weather conditions, potentially causing accidents without warning.
The affected production period spans from July 23, 2021, to December 5, 2023, when Stellantis finally implemented updated HCP software in production. Owner notification letters began going out around April 5, 2024.
Technical Service Bulletins: Additional AC Issues
Beyond the formal recall actions, Stellantis has issued several Technical Service Bulletins (TSBs) addressing air conditioning problems in various Grand Cherokee models.
Battery Chiller Problems in PHEV Models
Technical Service Bulletin 08-122-25, issued in April 2025, targets air conditioning problems specifically in 2022-2024 Jeep Grand Cherokee and Grand Cherokee L PHEV models. This bulletin identifies a supplier quality issue with the battery chiller component that can cause the AC system to blow warm air.
Affected vehicles typically display the diagnostic trouble code B3A11 (A/C Refrigerant Expansion Valve Actuator Control Circuit Performance) and illuminated warning lights. The repair involves replacing the battery chiller and, for 2022-2023 models, installing an additional wire harness jumper. This repair takes approximately 1.5 hours to complete.
Earlier HVAC System Issues
For owners of 2019 Grand Cherokees, Technical Service Bulletin 24-009-19 addressed automatic temperature control problems where the HVAC system would overheat the cabin during startup in cold temperatures. This created a situation where occupants’ upper bodies would feel significantly warmer than their lower bodies.
How to Check if Your Vehicle Is Affected
Wondering if your Grand Cherokee is included in any of these recalls or service actions? Here’s how to find out:
Using Your VIN to Check Recall Status
The most reliable method is using your vehicle’s 17-digit Vehicle Identification Number (VIN) to check recall status through the National Highway Traffic Safety Administration’s recall lookup tool. This official government resource provides the most up-to-date information about all recalls affecting your specific vehicle.
Simply enter your VIN, and the system will show all open recalls applicable to your Grand Cherokee.
Contacting Chrysler Customer Service
You can also contact Chrysler customer service directly at 1-800-853-1403 to verify your vehicle’s recall status and locate authorized dealers for service. The Mopar website at recalls.mopar.com offers another verification pathway specifically for Stellantis vehicles.

Stellantis typically processes verified reimbursement requests within 60 days of submission. Make sure to keep all your documentation organized when submitting your claim.
Common AC Problems Not Covered by Recalls
Not all air conditioning problems in Jeep Grand Cherokees are related to the specific issues addressed in these recalls and notifications. Many common AC problems fall outside recall coverage and require traditional repairs.
Typical Non-Recall AC Issues
Here are some frequent air conditioning problems Grand Cherokee owners face that aren’t covered by recalls:
| Problem | Symptoms | Typical Repair Cost |
|---|---|---|
| Low refrigerant due to leaks | Gradually reduced cooling | $200-500 |
| Clogged cabin air filter | Restricted airflow, musty smell | $30-100 |
| Faulty compressor clutch | Intermittent cooling or complete failure | $600-1,200 |
| Electrical system issues | AC functions erratically | $200-600 |
| Condenser damage from road debris | Reduced cooling, visible damage | $400-900 |
R-1234yf Refrigerant Complications
Some 2015 and newer Grand Cherokee models have experienced compatibility issues with the newer R-1234yf refrigerant system, which replaced the previous R-134a refrigerant. These issues often appear as expensive evaporator failures that require extensive dashboard disassembly for repair.
These refrigerant-related problems typically cost upwards of $2,600 to fix and are generally not covered under recall actions—they require traditional warranty coverage (if applicable) or out-of-pocket repairs.
DIY Diagnostic Steps for AC Problems
Before heading to the dealership for non-recall AC issues, try these basic diagnostic steps:
- Verify your AC settings are correct (temperature, fan speed, and “AC” button engaged)
- Check for blocked vents or obstructions
- Inspect and replace your cabin air filter if it’s dirty
- Listen for unusual noises when the AC is running
- Check for visible refrigerant leaks (often appearing as oily spots around AC components)
More complex issues involving refrigerant leaks, compressor failures, or electrical problems will require professional diagnosis using specialized equipment. These problems can involve significant repair costs if not covered under warranty or recall.
The PHEV Connection: Why Hybrid Models Have Unique Issues
The plug-in hybrid electric versions of the Grand Cherokee face additional air conditioning challenges due to their complex integration of traditional and electric systems.
Dual-Purpose Cooling Systems
PHEV models use the air conditioning system not only for cabin cooling but also for battery temperature management. This dual-purpose design means that PHEV air conditioning systems:
- Work harder than traditional AC systems
- Run more frequently, even when cabin cooling isn’t needed
- Incorporate additional components like the battery chiller
- Use more sophisticated control software
This added complexity explains why PHEV Grand Cherokees have faced unique air conditioning challenges and dedicated recall actions.
When to Take Action: Prioritizing Your Response
Based on which issue your vehicle might have, here’s how to prioritize your response:
Immediate Action Required
If you own a 2022-2024 Grand Cherokee PHEV experiencing defrost or defogging system problems, schedule service immediately due to the safety implications. Unlike comfort-related AC issues, defrost system failures can create dangerous driving conditions and shouldn’t be delayed.
High Priority (But Not Emergency)
For vehicles affected by Customer Satisfaction Notification Z33 (complete AC failure), scheduling service promptly is recommended, especially if you live in a hot climate or regularly transport passengers who may be sensitive to heat (like children, elderly, or pets).
Regular Maintenance Priority
For issues identified in technical service bulletins or non-recall problems, you can schedule service during your next regular maintenance or when convenient, as these typically don’t present immediate safety concerns.
Working with Your Dealer on AC Recall Issues
When you take your Grand Cherokee to the dealer for recall work, follow these tips:
- Call ahead to schedule an appointment specifically for the recall work
- Provide your VIN when making the appointment so they can verify eligibility
- Ask if they need to order any parts before your visit
- Confirm whether a loaner vehicle will be available if needed
- Bring a copy of any recall notification you received
Most dealers will provide recall-related repairs promptly, but during busy seasons or parts shortages, you might face wait times. All recall work is performed at no cost to you.
The Evolution of Jeep Grand Cherokee AC Systems
Understanding how Jeep Grand Cherokee air conditioning systems have evolved helps explain why certain model years face specific issues.
