2023 Lexus Is

I am reporting a severe, unresolved safety hazard involving my 2023 Lexus IS350]. The vehicle is continuously flashing 'Braking System Malfunction,' 'Crash Light,' and 'Engine Light' alerts on the dashboard. This is the second major acceleration and braking system failure since purchasing the vehicle brand new.The authorized dealership, Meade Lexus, has repeatedly failed to properly diagnose or repair this critical braking issue over a 7-month period. On multiple service visits, the dealership documented that they simply 'lubed' the rubber around the gas cap, reset the dashboard warning lights, and returned the vehicle to me without performing actual mechanical repairs to the braking system. The service manager explicitly instructed me that I must drive the vehicle back to the dealership every single week just to have the safety lights turned off manually. Driving a vehicle with an active, un-diagnosed braking and crash-system fault is a major safety liability and makes the vehicle dangerous to operate. The manufacturer and dealer have failed to resolve this safety defect under warranty."
