I have personal experience of this.
Lexus UK argued that it was “the way I was cleaning my car”, which it utter BS. The two bits of trim required for the dashboard are £1500.
However....
...my main dealer at Hedge End were very helpful - they always are. We’ve bought 5 cars so far from them and have a good relationship with the dealership. In my case, the parts were reduced via goodwill to substantially less and I decided to have them replaced. It’s annoying in a way, but my GSF has been such a good car, I’m trying to keep it in as good condition as I can. After nearly 4 years, I still have no idea what could replace it.
