Something to try....
I turned off the anti-skid feature (right most button) and it "seems" to help. I did this every drive since Tuesday PM and it seemed to really change the acceleration profile. Take note of where you have the hesitation problem, then turn off anti-skid and then repeat the offending maneuver.

Let everyone know if you see a difference.

In the upper midwest US, we have quite a bit of snow and ice, a couple of times the anti-skid kicked in and it dawned on me that it behaved almost the same - so I am trying an experiment on that mode.

"anti skid" ?????


I think that you are referring to the DYNAMIC STABILITY CONTROL


Read the warning in the manual


The vehicle's stability and safety may be reduced by inappropriately disabling the Dynamic Stability Control (DSC) system. The result can be a vehicle crash, potentially leading to serious injury or death.
Switching the DSC system off reduces the level of traction control intervention and may lead to an increase in wheel spin.

DSC is still anti-skid. Yes, I understand the warning. I grew up with manual brakes, steering into a skid, downshifting and actually driving etc. I have no problem drive with DSC off.
I realize that in the Canada OHS is all powerful, but in the US we still have "some" control over our our own destiny. Maybe that's why they have a button so you can selectively turn it off.

That said, this is an experiment if someone is comfortable with turning it off, see if it helps. LR is no use here, the problem is dangerous, period. I am in an area - right now - that is ... 0 degrees F and 10 inches of snow. I have NO problem with "DSC" off.
The problem with the hesitation is dangerous, LR and service will not engage. I hear from people in the UK, Canada and US that they experience the same lack of response from them (cannot reproduce or a design characteristic) with no help. All I am offing is a test to see if it could be related. For me, I see a marked improvement.

Success........................................... ............................!
I've been turning off the DSC (anti-skid) function since last Tuesday (January 22).
This has really changed the performance for me.
The Slow acceleration / loss of power problem is gone, except briefly when -20F and the car is cold, so I don't count that.
This made a major improvement to the acceleration problem so many are experiencing / describing.
I personally have no problem with turning DSC off. But the decision is yours based on your comfort level.

I will try to explain the effect next time I'm in (probably in a month or so) for the yearly service.
I don't know if they will do anything, I'm sorry to say as no one in LR has engaged on this yet. But I will try.

Given this was an experiment, I am very surprised that this worked for me as well as it did.
This tells me it's most likely not the transmission, but the software / code that controls these functions.

Thanks for posting these tips. Someone else has driven mine for 3 years so I definitely need a reset. As for stability control, I'm not going to delegate my extensive experience at stability control over to software. The manual pretty much tells you you're a walking talking hazard so I'll put that to the test. If this be my last post on this forum, you'll know how that worked out.

Reset Automatic Transmission:

0. Press "Start" button only. (ie: Do NOT start the engine.)
1. Press and hold gas pedal to floor for approx. 15secs.
2. Press "Start" button again.
3. Release gas pedal.
4. Wait approx. 2mins.; start engine and drive.

(Footnote: This process will renew the transmission program and erase the adaptive learning system to learn your driving style. If ever the system feels slow/sluggish just perform another reset.)
.

...how did you figure this out?

YOU ROCK -- THANK YOU!!!

I just tried this on my 2017 and it makes a world of difference accelerating from a dead stop. An additional benefit, and I'm 99% sure I'm not imagining this, is that the suspension seems much softer than it has lately, resulting in a much nicer ride.

Thanks Again!

Yep...it worked a treat for me too. It's like I'm driving a different rover now. Still not thrilled with Land Rover's transmission system overall but am learning to control it via pedal pressure.
