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, owners of late-model Lexus IS sedans have reported weak battery behavior, dead batteries, or no-start conditions after the vehicle sits for several days or is driven mostly on short trips. The problem is often linked to low reserve capacity, parasitic draw from connected services/accessories, or insufficient recharge from repeated short-distance use. Complaints typically involve a sudden click/no-crank event, warning messages, or the need for repeated jump-starts on relatively new vehicles.
Battery state of health and charging voltage should be tested first, followed by a parasitic draw test if the battery repeatedly discharges. Many cases are resolved by replacing a weak battery, updating software if applicable, and ensuring accessories such as dashcams or OBD devices are not staying awake. Owners who drive infrequently often benefit from a maintenance charger.

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.

On the 2023-2025 Lexus IS, owners have reported wind noise, buzzing, or a whistle from the windshield side molding or A-pillar trim area on late-model Lexus IS vehicles, most noticeable above roughly 50-70 mph or in crosswinds. The issue is typically caused by slight misfitment, loosened molding retention, or airflow around trim edges. While not a mechanical failure, it is a recurring owner complaint because it affects cabin refinement in a vehicle marketed for quietness.
Diagnosis usually involves taping off suspected trim sections during a road test to isolate the source. Repair may include reseating or replacing the windshield side molding, adding foam/felt at contact points, or correcting clip engagement and panel alignment. If prior glass replacement was performed, inspect molding fit and adhesive integrity carefully.
