‘has anyone with the rolling back or delay issue, had their Defender successfully repaired/updated and the issue sorted out?’

Yes I have ………… by rejecting and getting a replacement!

I know not a useful answer but I am so glad I went down this route as they had no solutions and no idea how to resolve, despite my dealer trying so many times. The difference in the replacement D350 is honestly astounding! I now understand why people were raving about how well the defender drove! MY25.5 Defender 90 D350 X Dynamic HSE - Maximus

Mine is a d350. So are you saying your old d350 did it and the new one does not? Mike

Yes that’s basically it. Old one - D350 rolled back, had rough, jerky gear changes, noisy and prolonged electric park brake noises, auto stop start never worked correctly and the ventilation system squealed like a pig! New replacement D350 has none of these faults. MY25.5 Defender 90 D350 X Dynamic HSE - Maximus

Not only is it going in to neutral at every stop it also makes a loud noise every time it goes back into first gear. So in traffic every time you pull away this noise comes on as it engages in to first, does everyone else have this noise? Here is a video of the noise when you release the brake: https://youtube.com/shorts/lh48Yky4zQY?feature=share

I'm going to go and try to test drive some other similar models to see if they all have this issue or maybe someone here already has?

Yes my D350 makes the same hissing sound. Whenever I hear it I just want to burn the car what a piece of junk.

Hardly a "piece of junk" because of that. lf the engine blew up,
it would be more justifiable statement.

l don't get any hissing noises from my D250 diesel though, maybe it's the air suspension making the noise (l don't have air suspension either)

I speak for myself, my D250 from MY 23.5 doesn’t make any kind of blowing or whistling noise, and it has air suspension…if you find yourself in a garage, or a tunnel, with no music and in absolute silence, windows down and close to a wall or another car, you can feel the slight action of the handbrake when it comes on, or the servo control of the gear change when you shift into D from N for example…and if you strain your ears really hard you can hear, or sense, the compressor in the distance if, in that state of silence, it decides to act…that said, I can say that all those elements were much more audible in my D3, by far, without going any further…so by no means, at all, would I define the Defender as a piece of junk… Defender 110 SE I6 D250 23MY

No the noise is the gearbox changing from neutral to drive. You can hear it in the video. You can even hear it when you shift from park to drive. It is nothing to do with the brakes etc.

I concur.

The hissing sound comes from the transmission selector area. It is minor and jenerally does not bother me too much. However, the acceleration jerk is

me off indeed.

I've had two diesel vehicles from new. The Defender and a Ford van. Both vehicles suffered from a sudden surge of acceleration a couple of seconds after trying to start
from standstill.

On the Ford van it was downright dangerous, you'd try to merge into a line of traffic and nothing would happen, then it was as if you'd been hit from behind it took off like a rocket.

Over time the effect diminished but it took a few thousand miles. On my Defender it was around 4,000 miles before it became smoother.
lt's fine now.

Yes the hissing wouldn't bother me too if it didn't jerk and roll back.. The hissing is another reminder that there is this issue, and that's what I don't like about it the most. It wouldn't hiss if it wouldn't go into neutral.
