NHTSA Complaint #11454211 — 2022 LEXUS ES HYBRID

I am writing about my 2022 Lexus ES300h. This pertains to the Auto Radar Cruise Control system and also the Lane Keeping Assistance function. First, about the Auto Cruise. On several occasions I have found that while approaching stopped vehicles at a stop light and I am about 300 yards away, driving 35 to 40 mph, the car maintains speed and approaches the stopped vehicles in a dangerous manner. It shows no sign of slowing down. Twice I let the auto cruise do what it was doing till about say 100 yards before the vehicles, and it still maintained aggressive speed so I had to hit the brakes. It seems like the vehicle is oblivious of the stopped vehicles in front, and in my opinion, behaves recklessly. And yet at other times it does sense those vehicles and starts slowing down. There is no consistency. Someone at Lexus said that while the car seems aggressive, it will surely stop in time and not get into a collision when the Auto-Cruise is on. Well, I am absolutely not willing to experiment and put my life and that of others at risk. Surely this radar cruise system is primitive. I also own a 2018 Tesla Model 3, and feel extremely safe and secure with its Auto-Cruise function. The second issue is regarding Lane Keeping Assistance. Again, with the Tesla, the car stays rock steady in the middle of the lane with AutoPilot. Whereas with my Lexus, the car behaves like it has had a couple of drinks, wanders around in the lane, even gets on yellow lines in the center of the road and then buzzes me about it like it was my fault! When we first bought the Tesla it used to weave around in lanes especially when a lane suddenly widens like when two lanes merge, but with progressive software updates, the early problems have been corrected. I find it ironical that Lexus is a few years behind Tesla in this technology. I realize of course that it is only an assist system and I am responsible for steering the car.
