Issues with lane-keeping assistance in a 2023 Nissan X-Trail

My 2023 Nissan X-Trail has done this twice; it applied the brakes only on the passenger side of the car at 70km/h whilst I was in the middle of the outside lane of a three-lane (in each direction road). It released them after about five seconds but I had to fight the car to stop it changing lanes and colliding with the cars in the middle lane. An alarm did sound but it went away quite quickly so couldn't see what it was; I had other things to keep me occupied at the time.

What is causing this?

This model X-Trail is fitted with active lane-keeping assistance which is sort of a helping hand when the driver isn’t keeping the car in the centre of its lane. It could be that this system is what’s causing the car to feel like it wants to pull you into the next lane.

You need to have this checked under warranty as soon as possible, since it’s an obvious safety issue. This isn’t just a Nissan thing, either. Many brands have had complaints about these systems, and in some cases, cars fitted with collision-avoidance systems have been known to slam on the brakes when the car’s camera 'sees' something like a wheelie-bin on the footpath and mistakes it for a truck entering the road. Speaking of which, your lane-keeping assistance is controlled by a camera at the front of the car. Have a quick check to make sure there’s not a huge dead bug confusing the camera.
