Could have been re-calibrated at some point. I had ACC activated, and it was pretty jerky, as I did not originally spec it. After I had it calibrated, it works great.

 

I’m not usually one to complain, but the Keep Lane Assist on my 2023 Range Rover Sport P360 is genuinely dangerous. When driving on the highway, the car tries to take every exit or veer off the road at every broken line on either side of the road, then violently jerks back. I’m sure everyone behind me thinks i'm texting on my phone or drunk. Worse, if there's a white vehicle nearby, it pulls toward it. I'm frustrated that Range Rover is aware of this issue, as seen in all the comments on this thread, yet seems reluctant to fix it — I cant believe they let the vehicle pass LP2 stage audits or at least issue a warning that the KLA is not performing as designed. It should honestly be called “Ping Pong Assist.” I took the car back to the dealer to see if they could recalibrate the system, but I’m not optimistic given all the similar complaints here.

 

All of these driver assist nannies are ridiculous. Like I am perfectly capable of driving and operating a vehicle. I don't need any help. While your LKA is definitely not working as it should, I think a recalibration would help. Also, there have been numerous OTA updates that have improved some of the ADAS features, and I'm sure more will be pushed in the future.

 

Emergency lane keeping feature is a horrible feature, but it needs to be deactivated each time you start the vehicle. Lane keeping assist can be toggled on or off from the steering wheel button. The worst is the Emergency Braking. My first experience with that is one day while driving, a car in front of me slowed down to enter a shopping center. Any capable driver can assess the speed one is traveling at, and the closing gap between you and the vehicle in front of you and determine that the vehicle will be clear of the roadway in enough time, just by taking your foot off the gas, although I usually hover my foot over the brake pedal just in case, (in the somewhat typical case of the driver with their eyes glued to their phone). This time however, the Defender’s system, thinking it is a better driver than I am, decided to slam on the brakes needlessly. Thank God the driver behind me was not too close, or as usual making an extremely important text to his/her friend about how much ketchup they put on their McDonalds fries, or which color shoes to wear to pickleball that day, and slam into me. Ever since then my routine before driving off is to disable Emergency Braking, Emergency Lane Keeping, and Auto Start/Stop. If only JLR could give us a way to create shortcuts to routines, like my iPhone is capable of, to turn all of these off with one click. Right now it takes 8 or 9 taps to complete that routine.

 

I must say that all the tech was desirable. I wanted to get something akin to my old Defenders and Series vehicles in capability, but with all that seemingly cool tech. I paid a silly amount of money for the privilege. Boy have I been disappointed. The lane stuff and braking seemed like a good idea, but the implementation was done by Cletus the slack jawed moron, which I suspect will debut as Apple's new AI (if Siri was any preview). The off road stuff is good, but actually no better than my old Range Rover's implementation of the same tech a decade earlier. Of all the cool tech, the only things I am glad I sprung for is the Clearview Mirror and the little cameras all around the car (which came in handy just this week). The rest is, in my not so humble opinion, fluff, poorly implemented fluff. I wish I could return most of it for a partial refund, or store credit. Like I so wanted CarPlay, little did I know it is subject to a host of random issues. Well I got what I paid for, I suppose. I think, all this tech particularly the proximity system and the telemetric are what makes it a total electricity hog, leading to the car constantly draining the battery. Oh and calibrating the system will not make the lane keeping any better. I had JLR replace my windshield and do the calibration, as Safelight was not able to do it. Still has that drunk kangaroo controlling it. I would start pulling fuses to odffload some of it activating, but then I would get a pile of warnings and it probably won't move.

 

 

As mentioned above, I have LKA turned off due to its poor and annoying performance. It's a pity.

But is there a separate "emergency" lane keeping assist as someone mentioned above? That is, an alarm or a stronger "nudge" to keep you from striking an adjacent vehicle? If it exists, does it remain active even with LKA turned off?

I haven't noticed anything like that being actually activated, but I certainly don't want to deliberately try or find out the hard way! If it's silently deactivated along with LKA, that would be quite a poor decision on JLR's part, as that would hopefully be a quite infrequent and valuable intervention.

 

Emergency LKA is always on by default, even if the LKA button on the steering wheel isn't activated and illuminated green. You can manually turn it off in the driver assistance settings menu. It resets with every ignition cycle, so if you turn it off, the next time you start the car, it will be activated.

I don't find it to be intrusive at all. There is one slip road on my commute where the guard rail is quite close to the lane, and occasionally it will sense the guard rail and try to nudge me away if I'm close to the shoulder line. There was another time when I went to make a lane change and didn't see a car in my mirror, so I went to change lances and the emergency LKA kicked in, as there was a car in my blind spot that I didn't see (nor was I paying attention to the blind spot monitor). It doesn't bother me at all and I don't feel like I have any need to deactivate it.

 

OK, that's good to know. Thank you. I definitely want it to intervene to avoid an accident! If it's been on all along as you say, it's never been a nuisance since I've never had an alert or intervention, and so I can't think of a reason to ever turn it off. Great!

 

You’ll find the option to disable Emergency Lane Keeping by going to:
SETTINGS>VEHICLE>DRIVER ASSISTANCE>COLLISION AVOIDANCE> there you will find the toggle for Emergency Lane Keeping and Emergency Braking.
