2017 LEXUS GS — Problems, Recalls & Safety Data

The system which has intermittent failure on my 2017 Lexus GS350 is the lane keeping assistance safety option. The system seems to work almost perfectly on straight highways. But highways with curves seem to fail at about a 50% rate and human intervention is quickly required. The car is available for inspection and demonstration of the system failure on a nearby winding road. My safety and my wife's safety were put at risk when I realized that my car was heading for a curb and not making ANY correction. I have not taken it to a dealer or any other kind of diagnostic facility. It has not been inspected by the manufacturer, police, or insurance company or anyone else. The system only has an amber warning on the dash when it detects no human inputs to the steering wheel or (I think) pressure on the steering wheel rim. There is also a dash warning when the system detects left/right lane marking swerves and it flashes "Stop for a Rest". I bought the car as a Lexus Certified Used Car just after hurricane Ian here in southwest Florida after my previous Lexus got flooded. Early on I noticed the lane departure and the lane assist on some rare instances did not respond properly. Since the car did not come with any owner manuals I could not determine whether I had not set the systems properly or not. And since the hurricane, I have not traveled long distances frequently with the car to determine a failure pattern. My son has a Lexus with similar features too but does not trust them. He said to have the dealer disable them.
