2022 Lexus ES Driver Assist & ADAS Problems

Within approximately three weeks of purchasing this vehicle, the blind-spot monitoring and rear traffic sensor systems were found to be completely inoperative. All dashboard warning lights related to these systems were illuminated the night before discovery, then went dark the following morning. A subsequent inspection by a licensed Lexus dealership confirmed the failure was caused by prior undisclosed rear collision damage. Both rear blind-spot modules showed zero CAN bus communication. The following diagnostic trouble codes were confirmed: U0233, U023387, U0232, P057113, P157800, P1152A, P160400, C13807E, U0163, C142571, and B1576. The rear bumper had been improperly repaired using adhesive rather than factory fasteners. The rear lamp was barely installed and misaligned. A screw was installed in an incorrect location. The dealership noted that attempting to remove the bumper to visually inspect the blind-spot modules would cause additional damage due to the poor prior repair. The blind-spot monitoring system is a primary active safety system. Its complete failure due to concealed structural damage constitutes a material safety defect. The problem was confirmed in writing by a licensed Lexus dealer. Supporting dealer inspection documentation is uploaded.

I purchased my car approximately four months ago, and the lights on my dash began blinking there was a warning to clean parking sensors. I went to the dealership to see what this meant. They stated I have a missing sensor and immediately stated it was not covered under warranty. I haven’t had any wrecks or bumps on my car. I asked if it could be a default with the glue that holds the sensor in place. The manager said that’s not possible someone had to push the sensor out. He continued to state they have had several cars come in with the same issue and people are pushing them out. This has caused warning lights to come on in the vehicle due to this default the dealership stated it was a wear and tear and would not be covered under warranty. It also causes the car to beep as if you are going to hit something every time you start he car. Even if you turn off the system, it still beeps and blinks as if your car will shut down. the parking sensors are defective in the sense that they are not secure and being installed which is causing repair approximately $900-$1000. I stated it has been extremely hotter than normal with a consistent temperature oaf 102+ in Arkansas. He was not open to the fact and basically said pay or leave. He refused to give me an estimate on the cost unless I paid the $100 diagnostic fee. I feel that if several people have been in for the same reason it’s should definitely mean there is something defective with the front bumper sensors. I have not even drove 10000 miles and now there is a repair not to my fault that I am having to pay as if the car is t expensive enough. I believe there needs to be some sort of recall on. This section with how they are installed. He said they glue them on the back side and glue does melt..please look into this.

The contact owns a 2022 Lexus ES300H. The contact stated that after the vehicle was stopped at a traffic light, the contact continued driving at an undisclosed speed when another vehicle in front of him came to a sudden stop. The contact stated that his foot slipped from the accelerator pedal and his vehicle rear-ended the other vehicle. The contact stated that the automatic emergency braking system failed to stop his vehicle. Additionally, the air bags failed to deploy. There were no injuries sustained. No police report was filed. The vehicle was taken to the dealer, where it was repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 33,000.

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.
