Rambox opened while driving

Picked up my truck from the dealer. There is an issue with the harness that is allowing water in as others have stated. The part is on back order until February. The service tech went through and did his best to make sure there wasn’t any water in the harness and also put some dielectric grease on the affected area as temporary fix.

Mine started yesterday(2021 Limited Longhorn) had the weird clicking noise in the cab first thing in the morning coming from the light on/off area?(Bottom left of dash by the drivers window vent). The drivers ram box was opening on its own after this happened, numerous times. Learned that pressing the lock button to lock the doors/boxes/tailgate right after getting in kept it closed while driving. But will be taking it to the dealer and also possibly pulling the connector for the lock as well. Would much rather have to use the key to unlock these than have them open randomly.

Had this same issue 3 days after picking up the truck didn’t think much of it until it started happening 2-3 times daily. 3 weeks goes buy noticed driver tail light not turning off took it to the dealer they think the body control module is bad anyways long story short trucks been in service for 5 weeks now back ordered BCM

This has been happening to me on my passenger side rambox. I've only owned for 2 weeks now. Haven't noticed issue on driver's side yet. 2021 Ram 1500 4x4 Laramie

This just started happening on my 2020, Driver's side only. Removing the Ram Box to get to the harness seems like a PIA solution but I guess it is what it is.

Mine was in for that issue today, and they do have a TSB on the problem. They also told me the part wouldn't be in until February, so until then I'll have to keep popping it closed.

I'm having the same issue on a 3 week old 21 limited. Glad to hear there is a TSB on it. Does anyone know if you call the dealership ahead of time with the TSB# if they'll order the part to shorten the process?

I’m having the exact same issue on my 2021 Big Horn. It’s in for service as I type this. The rapid clicking happened for me one day after I took it through a laser wash. The rapid clicking has stopped, but now I get the random opening of the driver side ram box. When I spoke to the service tech he said there is a bulletin out for it. I will hopefully be able to update tomorrow on their findings.
We certainly understand how this concern may be an inconvenience, everyone! If you are intending to address this with your dealer or have already had a servicing appointment, please send our team a private message with your VIN. Our team would like to investigate this further per each individual situation in order to ensure that the concern is fully addressed and resolved. We would also be more than willing to escalate a case on your behalf to a specialist for further support throughout that process, and are happy to assist with part order delays as well!
Thank you, we look forward to your follow up!

2021 1500 Laramie here also with the daily unlocking of the driver side rambox. I also occasionally get the rapid clicking by the rambox and in the cab. Planning on taking it into a dealer next week.

I have a 2021 Limted built in Oct of 2020 and have a possessed driver’s-side RamBox. It opens when the truck is off, and usually after I lock it up. Every morning, I see the driver’s side Rambox slightly ajar and I almost always remember to close it. If I stop somewhere, like the grocery store, it will be open again by the time I return from shopping. Nothing is in that side, and it’s been doing this for about two weeks. I have it scheduled this week and will let you know what the dealer says. The truck has 2,200 miles. I hope a TSB is already issued.

Check it out... In post #83 of this same thread, RAMGuy1981 says there is a TSB, and posts pics of it.

I have a 2020 Rebel built at the end of August 2020. Rambox on driver side keeps opening while driving or when is parked several times a day. Now I regret choosing Rambox . I called and scheduled an appointment at the dealer hoping to have it fixed.

It will get fixed, no problem. There is a TSB out on it, and mine just got fixed even though they said the part was backordered. It's a simple swap of a wiring harness, takes maybe half an hour. All good now.

It was for mine as well. The dealer replaced the locking mech and it hasn't happened since...knock on wood. Hope I didn't jinx it.
Well... apparently I DID jinx it. Because it started back AGAIN after a little bit of time passed since they replaced the mechanism. It started again Jan 14th and since then it has come back with a vengeance. It will pop open every single time I am away from the truck. It used to stay closed once I closed it from a random opening, but now... even if I close it and come back later it will pop open again. It "USUALLY" won't pop open when I'm driving, only when it is sitting. I saw it happen once (like seeing nessie, I was like oooooh!!) and you can hear something happen in the truck up towards the front almost like an automatic break engaging and then at the end it just goes 'click' and there goes the rambox. I have scheduled a second appt at the Ram dealership for today. It will be interesting to see what they find out, if anything. But this will be attempt number two, once I get to the magic third time things change and I will be investigating steps I need to take in order to get some resolution under the Lemon Law in Georgia. I'm SURE that won't be a fun journey either, and I really like the truck but I don't need wings popping open going down the road or to broadcast to everyone "Hey sticky fingers, come see what's in my toolbox"

Did they replace the wiring harness? That's the problem, not the mechanism itself.

The first time I'm not sure what part they replaced, but something was replaced. This time (yesterday) the mgr said thanks to the service bulletin I got a picture of from this forum he knew exactly what to look for and confirmed I was indeed having a water issue. So he disconnected it and ordered the part. So now I wait to get the replacement, he had no confirmed delivery date so I'm not sure how long it will take. So I'm optimistic...course I was the first time too! We'll see.

2020 RAM Black Appearance Package and my drivers side Ram Box has literally started this week in doing this. VERY concerning to say the least. Im glad I didn't have anything to fly out while going down the interstate or for something to get stolen. I need this fixed ASAP and dealers remotely near me dont see this as a safety or security issue and are "backed up for the next 2 weeks"... please help
We have the same truck, mine is Limited, and my driver side box has been opening constantly. I walked out yesterday and closed it and within a minute I heard the box unlatch. It’s the driver side box and my tail light on that side also stays on.

This is exactly what’s happening to mine. I had issues with the Box a few months back and then it stopped for a while. About two weeks ago the driver tail light where the amber blinker LEDs are stayed on as Red when I shut off the truck. Then all the sudden the Box on the drivers side started opening again.

Sign me up for box opening problems. Mainly my Driver side box but has also happened to the passenger side. After reading all of these I called the dealership and asked if they had any problems and told me they were not aware of any but would look at the truck for me. Not sure if there is a service bulletin they are not aware. Will see what they say.

There is a service bulletin for it. Go back through this thread a page or two. You’ll find it. Take note of it so you can inform your dealer.

I found bulletin and printed. Took with me to dealership. They said it was the first they had saw this. Apparently so common that the harness is on back order. Could not give a idea on when it would come in. Were nice and helpful but surprised they had not come across it yet.

Hi RamCares! I'm the newest member of the Rambox Opening Club. For the last 3 weeks and several times per day, I will find the driver's side Rambox opening by itself both while driving and while parked. Several times while I've been on the highway and just this morning, got pulled over by a police officer to alert me to the lid flapping in the breeze. The circumstances are similar as everyone here - no set pattern, the lock mechanism opens and closes very quickly for several minutes while I watch and it does not appear to be a mechanism or alignment issue. I have a dealer appointment later this week and will show them the bulletin posted earlier in this thread.
