2023 Lexus IS 500Recalls, problems, MPG & safety

“I am reporting recurring infotainment, display, audio, and related electrical malfunctions with my vehicle that have continued despite multiple visits and repair attempts by an authorized Lexus dealership. The problems began when the vehicle was relatively new and have continued intermittently. While driving, the vehicle's audio system can suddenly cut out completely at different volume levels and without warning. When this occurs, normal audio functions are lost and the system generally does not return to normal operation unless the vehicle/system is restarted. The infotainment/display screen also intermittently shuts off, goes black, and/or repeatedly reboots while the vehicle is being operated. These failures can occur unexpectedly while driving. The display is also used to provide visual information and warnings associated with vehicle safety and driver-assistance systems, including Parking Collision Warning and Rear Cross Traffic Warning. When the screen unexpectedly shuts off, goes black, or reboots, these visual warnings can be interrupted or unavailable on the display during the malfunction. This creates a safety concern because visual information…”

“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."”
