Ram has an issue with the electronic brake module. It effects the anti-brake, anti-slip, trailer brake, and cruise control. They are aware of it and it is documented on many forums as far back as 2016 on my model. My son has a 2018 2500 and is starting to have the same issues. This is an $1100 job but they don’t have the part and can’t get it. They say it is on back order? No real guarantee it will even last when it is replaced. This is a hazard driving. And definitely an issue you need to address
