Vehicle began exhibiting multiple electrical safety issues around April 2025. EMF (electromagnetic field) levels were measured and found to be excessively high, causing physical discomfort and triggering health concerns for my disabled son and me. We both sought medical attention. Two independent mechanics inspected the vehicle and confirmed it showed signs of water intrusion or exposure to hazardous materials — including corrosion, damage to internal components, and abnormal underbody residue. I reported this to Lexus in April and also submitted a lemon claim, but they have failed to act or resolve the matter despite multiple follow-ups. Additional issues include malfunctioning GPS, flickering interior lighting, and system errors suggesting possible electrical instability. I no longer feel safe operating the vehicle due to the ongoing risks and lack of manufacturer response. This is a serious failure of duty to inform, inspect, or repair — and may indicate deeper electrical or structural defects that pose risk to others.

Coming down a steep, narrow, long driveway leading from a private home on a hill, and moving forward in low gear, I allege that the brakes failed. After 3-5 attempts at braking, we came off the cement driveway as we accelerated and slid off the side of the hill, turning over onto the driver's side of the car and coming to rest near a dropoff, held by the branches of an oak tree. Fire engines came, and the Jaws of Life were applied, basically demolishing the car (which did hold together as we slid along). The seat belts also did their job. The car was removed from the towing yard in Grover Beach, CA, to Fresno, CA, whereupon the car's computer was inspected by an engineer hired by Lexus. He reported no failures. Besides me, the driver, there were two other occupants. My sister has sustained whiplash, and her boyfriend is having some pain in his hip. I seem to be fine. The other occupants were held in place by the seat belts. I was held by my belt and was also resting against the side air bag on the driver's door. The passenger's front side air bag also deployed. There is no confirmation of a problem by the dealer or an independent service center, unless the engineer counts as independent. Other than the engineer, I don't know of any inspection of the vehicle. The Highway Patrol was on the scene but did not write a report as we were on private property. No warning lamps came on that I observed.

The passenger airbag light is constantly on. When no one is sitting on the chair, the light states that the air bag is off and when someone is sitting in the chair, the airbag light states that it is on. I just purchased this used car a month ago from a Toyota dealership. Two weeks in with no accident whatsoever, the problem had occurred. I noticed the airbag light turned on when I first purchased the car but it would quickly turned off completely after a while.

The forward collision not working when it raining. I took to a dealership and they said they test the system not the car and everything it okay. I did a test myself today (10/13/2022),and the system didn't work. They advertised that on national tv and it not working. The sales person convinced me to get this car because it very safe for my family, and failed miserably. What lexus is doing called false advertisements, and I need your help to fix this situation with my car please.
