2022 Lexus Rx

I purchased the 2022 Lexus RX 350 used a couple of months ago. While driving down the highway the instrument panel went blank. I was terrified. I continued to drive not knowing what speed I was driving. The instrument panel went panel came back minutes later. Another incident occurred when the car was parked in my driveway. I turned on the engine and the instrument panel was blank. No numbers and no information on the instrument panel. As I drove down the street slowly the instrument panel returned to normal. A third incident occurred when occurred as we were driving on the highway. The light on the instrument panel began to darken. My husband was driving and I was in the passenger seat I was able to access the light app on the dash and restore the light to the original setting. This car is not on the recall list. It should be because this is a matter of life or death. The car had 59000 miles on it when we bought it so it is not under warranty. I contacted Lexus and they refused any help until I take it to a Lexus dealer and have it diagnosed. I don’t drive it daily because I have other vehicles but I would like to be able to drive it and have full use of the instrument panel. The problem repeats itself.
