Abrupt throttle tip in
After slowing to a crawl, say entering garage, and then reapplying throttle it's difficult to modulate the gas and the car accelerates somewhat abruptly.
It requires a very measured application of the gas and is a little annoying.
This is a CPO 2024 E450 with 7000 miles in comfort mode.
Is this typical ?

I think i have a similar issue, it seems to me that if I try depressing the gas slightly as the car is downshifting from 2 to 1 the car will lurch forward. It happens to me as I try to move the car a little further up the driveway incline which causes the downshift. In my previous W213 and my W238, the transmission always started out in 1st, but after stopping it will only downshift to 2nd gear so never had this issue. I find sometimes the W214 will remain in 2nd when stopped if I am at a downhill road traffic light.

Try using Drive-away assist which is part of maneuvering assist: https://www.mbusa.com/en/owners/manu...ve-away-assist
It was on and I just turned it off and will see

Maybe that's it
I'm also wondering if stop/start is happening in my case and the sudden request to restart after possibly stopping causes an abrupt change

This appears to be common. It is my only issue with the car - otherwise it has been superb. But this bothers me as it is a VERY common occurrence. Appreciate it if anyone finds a solution - however I think it is not due to start stop and just an intrinsic, unalterable flaw.

I have had it happen very rarely, only at lights or small inclines to get into places when trying to creep forward/feather the throttle. Never had it happen backing into parking spots or my garage.
It's more like a hard shift. I've also suspected auto start-stop needing to change states quickly and also what @estark mentioned about the car stopping in 2nd gear. I have noticed that after a full stop and start, the car restarts in 1st gear but it's possible the combination of auto-start stop + the transmission being in 2nd may be the cause. I wonder if the car thinks it needs to shift down to 1st due to the auto start-stop and then when we start again, it immediately tries to shift back up to 2 and somewhere there it causes the abrupt acceleration.

I think the issue may be that it's not in 1st already when moving at a speed that is barely walking speed. Unless I am misunderstanding the initial post. I'll have to look at the gear indicator next time I'm parking on my garage, but I don't recall it ever downshifting since it was likely already in 1st when I slow down to a crawl to enter my garage.

In my case if I wait until it is in 1st, there is no issue, When I enter my driveway it is typically in 2nd, and then I slow down further and it downshifts just as I am feathering the gas pedal and then it will occur.

Vehicle really shouldn't downshift to 1st gear in comfort though, for example, the previous generation, so W213 E-Class stays in 2nd gear even if fully stopped. To prevent roll back, hill climb assist was activated. Although when starting the vehicle first thing in the morning, it starts at 2nd gear until the transmission gets up to at least 3rd gear.

I noticed my car doing this the first 1000 miles or so but have not noticed it much or if at all the second 1000 miles, nearly 2K on the car already. I think though that is a good suggestion UA made of manually putting the car into 1st gear with the paddle shifter when going slow and maneuvering. My first thought was when I first experienced this when the car was nearly new was maybe it had something to do with the hybrid e motor kicking in a little when you first started stepping on it. It was a little bit of learning curve when I first started driving this car as a stiffer spring is used for the throttle over my last 213 wagon.

I have noticed that in either comfort or sport mode the transmission will shift to first gear about one second after you come to a complete stop, otherwise it will stay in second gear.I would come to complete stop before going into the garage, open the garage door and then go slowly in and it will stay in first gear and you should have no more problems.I learned to basically live with this awkward transmission
