Flat spot in acceleration while cornering w BT?
Anyone experience a lull or interruption in power when cornering?
It only lasts a second or so, right about at the apex, but I don't like it.
When my foot says go ... I wanna' feel that torque!
I will comment that this thing is a 5,000lb rocket on highway acceleration.

The other day I was trying to quickly get off the parking lot before the oncoming car got too close and at first the ML jumped forward but then the system kicked in and almost stopped the car. I think that the wheels lost traction by jumping off the curb and the ESP hit the breaks.

I have the same problem on a '13ML350BT. I noticed it last when I was turning left to go onto a freeway on-ramp. As it was an on-ramp, I put my foot in it, but nothing happened for a second or two. Very disconcerting. As I have other issues with it and it's going into the dealership, I'll have them check it out. The rain sensing wipers have lost their mind, the panoramic roof stopped working, it was low on coolant, etc.

Are you sure this is not just the ESP kicking in? It happens to me as well if I go a little heavier than usual on the right pedal. The car senses that more power will likely induce drift so cuts down the power.

Is it possible the tranny is not in the right gear and it takes a second for it to downshift in the turn. My ML had never shown this trait and seem to do fine in the turns when I want to accelerate.
Does it do it on every turn?

Thanks to the others too, I wasn't pushing for a drift quite yet, it only had 150 miles when that happened.
My first thought was turbo lag, but gear hunting by the new transmission/driving may be valid.
I'll try to recreate it this weekend.

Thanks, sounds similar, but I wasn't really getting on it, just mild acceleration. Thanks to the others too, I wasn't pushing for a drift quite yet, it only had 150 miles when that happened.

And the Audi Q7 transmission (made in Japan) is absolutely silky smooth!

It IS a shame.

I think he is referring to the fact that when in comfort mode, you start out in 2nd gear, not 1st, from a start. Only in sport mode does the car start in 1st. this is more for saving fuel and having a smooth start than disabling a gear. This is not just MB that does this.
