there is a new service bulletin out on this T-SB-0019-20 dated march3,2020 . Just came out Replace electromagnetic clutch assembly in transfer caseHi all,
I just bought a new 2019 Adventure trim and I'm wondering if anyone else with AWD with the Rear Driveline Disconnect feature has noticed a slight "clunk" noise when braking, right around 19-20MPH.
I'm thinking it is the driveline disconnect re-engaging the rear wheels, because when I set the gauge cluster display to show the engagement and torque vectoring of the AWD system, the noise correlates to when the driveline is engaged and re-engaged on the display. When I put the car in sport mode, which forces AWD all the time, the noise does not happen on deceleration/braking.
It mostly happens during deceleration/braking, but only occasionally during acceleration, right as the display indicates power has been cut from the rear wheels (as I've gotten up to speed).
I took it to a Toyota dealership but the Techs there acted like it was a spaceship that they had never seen before since it is so new, and had no idea it even had rear driveline disconnect, or what that even was. They said it didn't sound "bad" but admitted they heard the noise too.
At the end of the day, I guess I'm asking "Does anyone else's Adventure or Limited with the AWD make a slight clunk noise when braking around 19-20 mph?"
