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.

Thanks for the details, but I'm frankly offended every time Chrysler tries to suggest that the answer to the manual hatch bug is that it's normal operation and customer education is the solution. IT IS NOT NORMAL! It doesn't only happen after 3-5 times on the same ignition cycle.

I arrived from a red eye flight to the airport, got to my car in the parking deck and couldn't load my carry-on bag into the back because the hatch refused to open. How is this 3-5 times if the ignition wasn't even On yet?

My wife and our friends drove home from a restaurant. We approached the car, opened the hatch and put our leftover containers in the back. I drove to my friend's home to drop them off and the trunk refused to open to let them get at their leftovers. This would've been the second time to open the hatch on the same ignition cycle (if it had worked, which it didn't, so I really only got one opening).

The examples go on and on. The "3-5 times per ignition cycle" is NOT THE ANSWER.

And even if it somehow was, who's the idiot that decided this spec? What car in the history of the automobile has operated this way? Are we going to limit the number of windshield wiper swipes per ignition cycle next? It's not based in any form of reasonable logic and I wish they'd stop blaming the customer.

Hey, I completely understand your frustration. This issue has been confusing and annoying for a lot of owners. For some context, that 3 to 5 cycle lockout behavior actually isn’t unique to the Charger. It’s also present on the manual hatch systems in vehicles like the Grand Cherokee L and others that share the same latch assembly which share the same bullitens on operation.

I didn’t design or decide how that system works, but the reason it operates that way is to protect the Body Control Module. The BCM is the module that controls the manual hatch, and it limits how many times the latch motor can be activated in a single ignition cycle to prevent an over amperage condition.

There’s another part to it too. The BCM can block key off hatch requests if the 12 volt battery voltage is too low to support the latch motor. Sometimes even after starting the vehicle, the hatch may still not open until the Integrated Dual Charge Module brings the 12 volt battery back up to an acceptable state of charge.

From what I was told from the last engineer I talked to, the upcoming passive entry software update should help with both power and manual hatch concerns. That update is what I mentioned in my video, and we’re still waiting for it to roll out. It should resolve or at least reduce these issues once it’s available.

INCOMPLETE. It has been extensively documented that many people with an R/T and manual trunk are absolutely, unequivocally not suffering this problem because of a 3-5 cycle-per-ignition issue.

Moreover, the actual resolution to opening the trunk, when this happens, is not by going into sleep cycle. Simply, your video is incomplete.

COMPLETE. I mentioned in the video, and the post above that we are waiting on the Q4 Passive entry software update which is the update that's supposed to resolve or mitigate this issues. That's why the update was pushed from Q3 to Q4 to address this concern.

That 3-5 lock out timer is absolutely a thing, it's present on other vehicles that share the same latch and manual hatch system like the Grand Cherokee L, and customers should be aware of it. It's absolutely something that can happen, and infact something that is happening in my bay at this very moment on a customers vehicle. The solution for it being timed out is going through a sleep cycle.

The temporary solution for the passive entry fault until the software is released is a battery disconnect but I can't recommend that in videos anymore be you guys are tearing your cars up and they're blaming me for it.

I can only provide information I'm given, I cannot go on assumptions without official documentation and I gave the information that was provided to me.

Damned if you do and damned if you don't. @MoparTechJordan thank you again for this video and your willingness to provide at least some answers and a bit of clarity where nothing can be heard from Stellantis other than crickets. Were it not for you, I think many of us already would have said to hell with it and dropped our Chargers on the front lawn of the nearest Dodge dealer.

To everyone here venting: I get it. You've probably seen me vent as well, even to Jordan several months ago on the "you're closing it wrong" instructions about the frunk (which I still refuse to accept - Stellantis, F*** YOU for that one, seriously). Just know that Jordan is not a Stellantis employee, and he can only give the info that Stellantis' lawyers allow to trickle out. He doesn't have all of the answers either, he's just doing his best to support us where Stellantis continues to fail us.

Just another symptom of maintaining this platform like the ICE version. They could have just put the 12V battery in the frunk - you know, the thing you can actually open with zero power available - but of course that's not where it will be for the ICE cars, so we get to deal with the 12V battery being buried behind a panel under a hatch that has no reasonably accessible mechanical release.

The douchebags involved in making this decision deserve to be named, shamed, and blacklisted from the industry.

I appreciate your time to post this info Jordan. I can understand why people are frustrated by the info, but you're just the messenger. Stellantis is treating an obviously terrible engineering decision (or mistake) as if it somebody actually wanted it to work that way. Realistically; no reasonable product manager would intentionally let a car be designed to only allow 3-5 openings of the trunk per key cycle.

It's just real kick in the nuts to have the "hatch opening limit" combined with the fact that the manual hatch cars don't have any trunk release button inside the car and no key fob button to pop it. The easy entry button is literally the only non-emergency method to open the trunk. And on top of that; there's a powered button to open the frunk; which the non-plus cars just have blocked off!

My 24 Scat doesn't have the trunk problem yet, but it bricked over a month ago and the dealer has had it ever since. I sure do miss that car though, but my Challenger is getting some use, and It Doesn't Brick!
