Rambox opened while driving

[flyingpoint]

My 21 Limited's rambox popped open during our vacation trip a month ago. Brought it in today along with 80k miles service. Was told that the rambox TSB offer was expired already, but lucky that I bought extended warranty which can cover this issue. I do feel sorry to the truck owners who have to pay out of pocket to get this WELL KNOWN issues fixed.

My 22's Rambox opened by itself once on the highway.
I turned to the right and told her to properly shut it (slam it) an haven't had any problems since

My 2020 Rebel is doing this on the driver side. Have had the harness replaced 3 days ago and after 8 hours and no rain it popped open and the lock stopped working. It seems like if you push the button there is a delayed reaction. Its happening now constantly. Have a 2nd appointment tomorrow and I hope to hell they do not diagnose it again and tell me to come back. Will be the 6th trip for this issue if that is the case and its about 45 mins away and I have to take off work. I brought the TSB from this form to the dealer and they fixed it apparently (still happens) just got the truck

My Ram Box started having the same issue this week. Of course it happen 1 week after my 3 year warranty was up. Anybody get the wire harness replaced at a dealership after warranty and want to say how much it cost?

My 2020 Ram 1500 Built to Serve edition has been doing this since December 2020, the dealership replaced the latch, thought it solved the problem for a while fast forward to 2023 it started over again after a hard rain.

So is the new harness going to cost anything to replace since mine is out of warrenty

Replaced my cable harness with the one listed. Took about an hour. It fixed the problem of my box opening randomly. Bought the cable on eBay for roughly $50. I applied some dielectric grease around the connectors to help prevent water from getting into the connector.

I had a similar issue and thought I would post the symptoms and fix here for future searches.

• The issue was the driver's side RamBox would open after approximately 30 seconds of getting out and closing door. Once I physically closed it, would not open with the button or even the key. Not the same as opening randomly driving down the road like others have mentioned here.
• I took the latch cover off and saw the cable that the key is attached to was off the mounts that hold it so it will open the latch. I fixed it and added a zip tie to hold in bracket so it would not fall out again.
• The key would work now but it still had the other issue of opening after getting out and not opening once closed again.
• Unplugged the wire connector and it would not open with the button or after getting out but could NOW open with the key.
• Ordered new latch assembly since the circuit board that controls this function is in the latch unit. This fixed the issue completely.

The reason I think this was happening is that since the RamBoxes are tied to the locking functions of the car the latch had a short or electrical problem that made the truck think that the latch was malfunctioning, and the truck was kicking in the safety feature that would unlock the door (not locking someone in the vehicle). When driving the key was in the truck and would not open any other time, just when closing the doors and walking away.

I bought a new button ($15.00) just in case and new latch assembly ($45.00) off eBay to complete the fix.
Will hold on to the button since the front doors and RamBoxes use the same one.

I had the TSB fixed on the Ram box, dealership found by replacing the electrical pig tail a short further underneath another connection. Near the rear axle. Water moisture was entering the plug causing corrosion.in the pin area. so another section of electrical wiring had to be replaced.

Ya I dunno. Might as well get it replaced and see if it happens again. Good thing about warranty no money out of pocket. Only inconvenience is going to dealer

I changed all that on my truck and still didnt work. The ram box kept opening. Also rear light kept turning on buy themselves. Along with the smell of something burning insde the cabin.

Add me to the list of Ramboxes opeing

I bought my 2020 (used) last January and just a few weeks ago, the passenger side box kept popping open. Finally got it to stay shut, and now just a few days ago, the driver's side is doing the same thing. I have an extended warranty with this truck. So I dropped it off yesterday am to have a few other things, and the boxes addressed. I called back in the afternoon to see how things were going and the service manager said they couldn't figure anything out with the ramboxes. I re-explained the on/off buzzing sound I had heard coming from the switch area when it was open and he said, "Oh I didn't know that. We'll need it at least another day to start chasing wires. This is not a common problem." (I did explain that before dropping it off). So I started looking and found this thread, read through it all, and even had copies of post #83 from RAMguy1981 regarding the wire harness swap ready to share with him. But when I called him back, he was pretty short with me. He didn't want to hear anything at all about a TSB or what I thought I learned through my reading. "There's a lot of misinformation on the internet Derwood. Just let us handle it." So we'll see what he has to say. I read that the TSB has expired. But I'm hoping with my extended warranty, it can get covered.

Lots of great info on here!
