Oct 13, 2022Lane DepartureDriver assistance

The forward collision not working when it raining. I took to a dealership and they said they test the system not the car and everything it okay. I did a test myself today (10/13/2022),and the system didn't work. They advertised that on national tv and it not working. The sales person convinced me to get this car because it very safe for my family, and failed miserably. What lexus is doing called false advertisements, and I need your help to fix this situation with my car please.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Lexus Nx300 verdict →
