I have a 2019 bighorn, with the e torque motor and this happend to me the other day. I have 1000 miles on it, and had a full crew of 4 in the truck. It made the noise on deceleration and acceleration , almost was like a hole in exhaust or driveline problem. Has not done it since, I am scheduled to take to dealer in a week, but the problem is gone. Everyone in the truck heard it, as it was quite annoying. Glad to hear I’m not the only one and hopefully they will figure out a fix
