Lag and bump/clunk when accelerating

[DrBad]

I believe I've seen reports in the past of people experiencing a bump while in snow mode but lately while just in All-Purpose I've been getting a very noticeable brief lag like a slippage tthen bump/clunk as it kicks in. It's very annoying as it happens any time going from steady speed to accelerating and seems more noticeable going up hills. I've got a service appointment for late June. Gen 2 R1T Dual.

That's the rear motor engaging as power demand is increased. Well documented. Some have had luck with the rear drive unit being adjusted, some haven't. Most of us live with it, and just hope we get an "awd lock" button at some point in the future.

Snow mode, or reduced stability control will keep the rear motor engaged. Driver+ will re-enable the stability control though. Snow mode will keep rear engaged regardless, but reduces throttle inputs and reduces regen braking forces.

Currently no good answer.
