I have never driven a vehicle with drive assist/lane assist features for extended periods of time before I bought my Golf in March of 2020, new from the dealership. I became acquainted with the feature almost immediately as it is always ON by default - the first time the feature had a glitch was within a month of driving my car. I was on the highway, going 100 kmh, passing a long-haul van and suddenly out of nowhere the drive assist jarred my vehicle out of the lane I was in, I had to forcefully hold the wheel to steer back in my lane. I had no idea what just happened, I was alone and quite shaken in my vehicle and couldn't make sense of the situation.

A few months later, a similar "freak" took over/happened. This time however I had a good clue as to what was triggering the lane assist to behave erratically, such as during a rainy drive, rots with water formed on the road and the vehicle was reacting to the water rots which formed glistening lines in the middle of the road, so my car decided I ought to drive in the incoming lane and proceeded to do just that. I was lucky there was no on-coming traffic and avoided a possible head-on collision. The next time a similar occurrence happened was with the shadow of electrical wire running along a county road, the vehicle had no other reference lane markers so it picked up the shadow and again steered my vehicle in the oncoming traffic, and this time I nearly hit a passenger vehicle.

I am now asking the dealership to deactivate the feature and escalate the matter to VW Engineering team to recognize the danger of the glitch. I am told however that the only thing they can do is to check for software updates and see if there is calibration to be done... and then nothing...

And to top the sundae, I just got a rock in my windshield last week that resulted in a growing crack (at the bottom and not in the camera sensing path but still... a problem that VW will point out as a flaw and they cannot investigate my sensors because of the break to the glass...)
