On the 2023-2025 Lexus IS, some owners report intermittent pre-collision system, radar cruise, or lane-support warnings on 2023-2025 Lexus IS models, often after heavy rain, road grime buildup, windshield contamination, or minor front-end impacts. The system may temporarily disable with a message indicating the camera or radar is unavailable, even though no permanent hardware failure exists. In other cases, sensor alignment or calibration drift after windshield or bumper work can trigger recurring warnings.
Inspect and clean the front radar emblem area and windshield camera zone first, then scan for stored ADAS-related codes. If warnings persist, perform radar/camera aiming and calibration, especially after windshield replacement, bumper repair, or alignment work. Replace the affected sensor only after confirming power, communication, and calibration status.

On the 2023-2025 Lexus IS, multiple owners of current-generation Lexus IS models report a persistent rattle or buzzing from the front door panel area, often near the speaker grille or inner garnish, especially on rough pavement or with bass-heavy audio. Lexus issued service guidance for door trim noise on this generation, indicating the condition is known at the dealer level. Owners typically describe the noise as intermittent at first, then easier to reproduce as clips, felt interfaces, or trim contact points loosen slightly.
Technicians usually road-test the vehicle to isolate the exact door and trim contact point, then remove the affected door panel and apply anti-rattle felt, foam tape, or updated insulators at the speaker grille, garnish, or clip interfaces. Broken or loose retaining clips should be replaced, and the panel should be reinstalled with proper torque and alignment. If the noise is audio-induced, verify the speaker fasteners and harness routing before reassembly.

On the 2023-2025 Lexus IS, a number of owners report front brake squeal, chirp, or groaning noises during light stops, especially when cold, damp, or after the vehicle sits overnight. This is commonly tied to pad material characteristics, rotor surface condition, or insufficient lubrication at pad contact points rather than outright brake failure. The complaint is more of a refinement issue, but it is frequent enough on owner forums and dealer visits to be considered a known nuisance.
Inspect pad thickness, rotor finish, and hardware condition first. Dealers or independent shops typically clean and lubricate pad ears/shims, resurface or replace rotors if glazing is present, and install revised pads or shims if available. If the vehicle has F SPORT brakes, verify correct pad compound and bedding procedure after service.
