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.

No issues with our 2013 blutec. Smooth as butter at all speeds and gears. The car already has 43k miles and is going great.

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?

DUTCH

This would be my guess, too.

DFW01E55

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.
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.

Common issue and complaint with MB. I have experienced this in other models as well. I think they still haven't figured out how to program a 7 speed yet. Now they are looking at going with 9 speed trannys in the future. Get ready JD Power!

DUTCH

Agreed! Not even after 7+ years of service. Shame on MB!

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

Barry45RPM

That's why now when you start up a "recent" MB, it defaults to a 6 speed at boot up every time. You have to press the button to make it a 7 speed.

It IS a shame.

DUTCH

That's news to me. What button?

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.

MB has had this feature for many,many years.

DUTCH

My 2014 ML350BTC starts in 1st gear every time, regardless of whether it's in Comfort or Sports mode.

Shrdlu

Mine does, too. This 2nd gear start mode must be a gasser-only feature.

GregGebhardt

Not on my ML350BT. Starts in first and finds 7th all by itself.

Had this same thing happen yesterday under similar circumstances - was doing a rolling (had not come to a stop) right-hand turn out of a parking lot with a slight dip from the lot to the main roadway and when I accelerated out of the lot, felt like the engine suddenly died and the whole car just seized up for second...I literally lurched toward the steering wheel a little bit, it was so abrupt. Was a little scary to say the least, but fortunately there were no close oncoming cars as I pulled out onto the roadway. Car seemed fine after that, but I'd recalled reading this thread previously so it occurred to me that this must've been what I experienced.
