I've got a 2018 with the turbo and it acts just like above, the worst being at slow speeds, barely rolling, then accelerating or turning. It feels like the car doesn't know what gear to be in, not a power issue. Even at the lowest hp/tq it would perform better than it does if all else were as they should be. It's very- very- difficult to smoothly/slowly accelerate from a stop. I feel like it wants me to drag race everyone when the light turns green, and for a second or two I basically do without trying. Don't get me wrong, I love that it wants to GO!, but for mpg and in congested downtown areas, etc, a nice-and-easy acceleration would be nice/safer.
Side note: Here are the basics (I'll post video/etc later): I also had a HUGE acceleration issue at around 4,000 miles. I had just entered I-5 near San Diego at a medium acceleration, all seemed normal. Then when attempting to speed up and switch lanes my car acted like it was governed at my current speed- no change in acceleration or rpm when I pushed the gas pedal, even for ~10 seconds- not even FLOORED. I would actually lose speed going up moderate hills at ~65 mph. It was crazy. Limped my car home and took it to the dealer the next morning. It acted super funky on the way to the dealer too. He worked me in, checked it out, and ended up reseting the computer and said not to use ECO mode. **Land Rover told him there is a software update that will address transmission/turbo issues, set to release Oct/Nov 2018. I'm in Virginia now and as of Nov 2018 they knew nothing of a software update in Richmond. I'm going to call Land Rover in Carlsbad, CA, to see if they have an update on the update.
