    Hi, I have a 2016 Ram 2500 4x4 with the Cummins diesel.

    It has about 22,000 miles, and I've done one service so far (truck was bought new last November.) I use the truck for towing our 6,800# travel trailer. i have about 7,500 miles towing, the rest unconnected.

    I've had zero problems with the truck and the towing is a breeze.

    However, lately I'm having an occasional instance where the Diesel exhaust brake will come on, by itself.

    I'd say it's happened maybe three times in the last two months. The truck is used daily; I fill up with decent fuel at busy pumps.

    When this occurs, I can hear the exhaust brake "on" because of the noise it makes (I am pretty familiar from towing the TT up and down hills in the Rockies and so forth.) There is a loss of power as well.

    The problem "goes away" by itself on a restart.

    I was going to mention this the next time I have it in for a service (maybe 30k miles) but I wasn't sure whether this was something I need to get looked at earlier.

    Thanks in advance for any advice.

    And lights come on the dash or message in evic indicating the eb has turned on?

    Greg - No, no evic notice, no messages at all.

    I just hear the distinctive rumble of the exhaust brake, and the loss of power.

    Problem comes and goes by itself. It does not appear to be related to anything I do or anything I switch on.

    It sounds like the symptoms of a sooted up turbo but man it is way too soon for that unless you do a lot (I mean a whole lot) of idleing. Makes me think something electrical like a bad sensor or faulty controller but those usually trip a CEL when that happens. Definitely time to see the dealer and let them see if the can find something.

    ^^^ Thanks.

    I'll monitor and get it diagnosed at next oil change.

    Yeah, I used to have a Mercedes Sprinter diesel, and am very sensitive to no more idling than necessary.

    I'll post back when I have more info.

    This happened a couple times in the last week, so I made an appointment at a local Ram dealer to take a look at it.

    I'll post back with the results.

    Well, the local dealer kept it for a while and reported no stored trouble codes or faults.

    They did a software update on three modules, not sure if it will help.

    At least I have it documented now, I guess. The tech said he'd really never heard of this happening where the exhaust brake would come on spontaneously.

    You should be running your exhaust brake on full ALL THE TIME.

    This keeps the turbo from sooting because it creates back pressure, and is ram's answer to turbo fouling.
