Adaptive Cruise Control and Automatic Emergency Braking alerts triggered

Nice! I have 200 miles on it after the ground connections were cleaned and so far, problem free. But want some more miles before I call it a win for my truck..

Stupid question but where are the ground connections? Am I able to clean it myself?

I asked where they were and the service manager just said “in the back” but didn’t elaborate because we starting talking about something else. They also only noted that the specific ground RAM told them to check was G803A but also noted “others in the rear to be corroded too.”

What I did notice was I always store my small bag of basic tools and battery jump pack under the drivers side rear seat. It appears the tech moved that bag to the passenger side so possibly behind or under the drivers side rear seat?

I wonder if ground G803A corresponds to the ADAS Module that was replaced. Unfortunately, that still doesn't completely solve the problem if other ground connections were cleaned and re-fastened. It would explain why both vehicles discussed above are now functioning without the errors. I have had both errors along with the lights in the mirrors staying on, even after doing several master resets. I used my OBD code device to clear the errors. If it comes back I will be going to the dealer with the info in this post.

Welp… ground corrosion was NOT the issue. Both alerts are back 500 miles after they cleaned the ground wires. Now scheduling a second service visit with the dealer. They better just replace the damn module this time.

Started the truck to head to the store and BSM alert came on and immediately followed by AEM alert. Drove to the store and when I turned the truck back on both alerts didn’t come back. So these intermittent issues seem to be back.

Yeah this is because they have no idea what is actually wrong with the trucks. I am ok with it taking time but I want to see a positive trend where RAM is able to start narrowing things down more consistently. It has been months of known issues and, regardless of how many are out there, they (RAM) should have a better trouble-shooting guide by this point.

Your symptoms are very similar to mine except I only have BSM malfunction, and (typically) only at the first drive of the day - and if I drive for more than 30ish minutes, it won't come back on for the rest of the day

This only started at 3,000 miles.

Couldn’t agree more. Scheduled an appointment to drop it off. Let’s see what RAM tells them this time.

Are you bringing yours to the dealer?

Likely I will eventually. I travel a lot for work so I need to find the time

Have them replace the ADAS module as I showed above and your problems will be solved. That’s it, that’s the issue here

I provided them the service report replacing the module resolved it. Not sure we can force any dealer to replace anything. RAM did not tell them to replace a module, so they didn’t. Maybe this second visit will be different.

Do you have an alternative dealer you can take it to?

I’ll give this dealer another shot then look elsewhere. There’s another dealer in the area. Press the issue again on the module when I drop it off.

Well, add me to this illustrious list of owners with issues regarding ACC and AEB problems. Looked down this evening while driving and the AEB OFF light was illuminated. Got to a parking lot and went into the UConnect screen and tried to play with the settings to see what would happen. Here’s a video. The truck would not let me change settings, and it kept reverting back to the old settings as shown.

Yea that is what happened to most of us. Hopefully it went away after letting the car sit.

I was hoping the same, but the light was still on this morning after sitting all night.

Update on my AEB warning light... Easter miracle occurred and while driving yesterday, I went into the U Connect screen and checked the status again. The AEB was switched to the "off" position, but I was able to select "ON" and the light went away. All is well for now. Service visit avoided for now. Thank GOD.

Unfortunately mine does the same, but comes back a day or two later even after you’re able to select “ON” and light goes away. Mines getting dropped off Wednesday.

Yeah, I'm fully expecting it to pop back on sooner than later. Please keep me posted on what they find with yours once you know something. I'd greatly appreciate it. Good Luck!

I see you took delivery in early March. Mine was delivered March 19th. Curious what your build date was?

Is the build date the number below the “S.L” on the window sticker?
