The factory-installed front spindle grille and bumper assembly on this brand-new 2026 Lexus Rx 350 suffered severe thermal material failure, resulting in extensive warping, bubbling, and physical melting under normal, predictable outdoor ambient daylight parking conditions. This thermal deformation poses an immediate safety hazard because the deformed exterior structure directly houses the vehicle’s critical front-facing advanced driver assistance systems (adas). This includes the pre-collision safety radar sensors, pedestrian detection cameras, and proximity sensors located right behind the front Lexus emblem and grille assembly. The physical distortion of the plastic mounting housing can cause sensor misalignment, resulting in unexpected automatic emergency braking, failure of the pre-collision warning systems, or sudden blind-spot radar failure while operating the vehicle at highway speeds. Lexus corporate (case #260917000986) officially inspected the vehicle and explicitly denied all warranty and goodwill safety repairs, formally stating the vehicle's body components are melting due to a "solar event" concentration. Furthermore, the authorized Lexus dealership service management explicitly stated that this is a widespread, "common issue" that takes only 5 minutes of outdoor sunlight reflection to cause catastrophic component melting. The vehicle remains in its exact original factory configuration with under 2,000 miles. It is a severe safety defect to manufacture a modern premium passenger vehicle with safety sensor housings that melt and lose structural integrity under normal outdoor sunlight exposure. The manufacturer is actively refusing to correct this material hazard, leaving the safety radar systems compromised.
The panoramic sunroof shattered while the car was parked and there were no occupants. Lexus USA refuses to acknowledge this defect and the dealership insists there was an impact that caused this damage. There was no impact. I have asked the dealer for a written report of their determination of the point of impact and to return all broken glass to me. I do not know yet if they will comply with either request. As the car was parked, there were no immediate safety concerns, but due to the risk of additional glass falling onto the driver and passenger seats, the car was not in a drivable condition. Had this happened while driving, the sound of the shattering and the glass falling may well have resulted in a reaction from me causing immediate danger to myself and others on the road. Unknown if problem has been reproduced, but this is not an isolated incident. Vehicle component had not been inspected by manufacturer, police , insurance reps or others. There was no warning or other symptoms of this problem.
