Whats up guys
I made a quick video covering the Dodge Charger Daytona rear hatch and passive entry issues, but I wanted to put together a more detailed write-up for those who want to understand exactly how the system works and why some owners are running into problems. Below Is some technical information you may find useful until the Passive Entry Update is released in Q4. It seems the majority of issues are from R/T owners who did not opt for the plus package and the STAR case below explains the limitation of the latch system on those units
1. Manual Hatch Limitations (STAR Case S2523000037)
- On R/T Base models without the plus package, the manual rear hatch is limited to 3–5 openings per ignition cycle.
- This is normal operation — the Body Control Module (BCM) protects the latch motor from overuse.
- If the hatch stops responding after multiple attempts, letting the vehicle go through a sleep cycle or cycling the ignition resets the counter.
- These cars seem to have the most customer complaints because of this limitation.
2. Jammed Items in the Trunk
- Many issues are caused by items wedged against the hatch.
- Bulky cargo can make the hatch difficult or impossible to open.
- Tip: avoid placing heavy or awkward items near the latch or cinch mechanism.
3. Manual Hatch Opening
- If the hatch is stuck, you can manually open it by crawling through the rear seats and using the keyhole on the latch assembly.
- There is no emergency pull tab like other vehicles.
- I demonstrate this process step by step in the video to make it easier to visualize.
4. Passive Entry Issues (STAR Case S2508000021)
- Some owners report that the passive entry feature stops working even when there are no Diagnostic Trouble Codes.
- Temporary fix: perform a 12V battery reset (disconnect and reconnect).
- Permanent solution: Stellantis has a software update planned for Q4 2025.
- Vehicles without Keyless Go rely on the BCM to validate entry requests.
This is the ultimate fix for passive entry and hatch issues but untill this software is released, we have to work with what we have. Im not sure if it will be pushed off again as it has been a rampant issues since the release of this bulletin in march of 2025
5. Power Hatch Module System Overview
- The Power Hatch Module (PHM) authorizes power hatch operations and monitors inputs from:
• Liftgate latch and cinch mechanisms
• Power Drive Unit (PDU) motors
• D-pillar switch
• Overhead console switch
• Exterior handle
• Pinch sensors
• Key fob or RF-Hub signals - The PHM checks for obstructions and can reverse the hatch if needed.
- Audible chimes indicate opening, closing, reversing, or obstructions.
- The PHM communicates with the BCM over CAN bus to validate requests and ensure safe operation.
6. Power Hatch Drive Units (PDU) and Latch Operation
- Two PDUs provide torque to lift or close the hatch.
- The hatch is assisted by coil springs and a gas lift cylinder.
- The power latch has a cinch/release actuator with multiple internal switches that provide feedback to the PHM.
- The system monitors hatch travel, direction, and obstructions to prevent damage.
- The cinch feature of the lach is what causes it to bind when objects are jammed against the hatch, it doesn't have the ability to release the tension and open.
7. Summary
- Most hatch and passive entry issues are software or logic related, not hardware failures.
- Aside from passive entry issues, The manual hatch limit and jammed cargo are the second leading causes of customer complaints.
- Understanding how the BCM can place limitations on the number of openings along with the remedy and manual release procedure are critical to owner experience
- If your hatch is stuck, remember: you can still crawl through the rear seat and use the keyhole to manually release it safely.
