Some customers may notice an abnormal noise \(i.e. whine, groan, rattle or squeak\) coming from the front combination lights when turning them on, or a few minutes after turning them off. The noise may be due to contamination by foreign matter during the manufacturing process and the fan motor bearing may become worn out during use. To eliminate this concern, the fan motor has been modified. NOTE: It is normal for some noise to occur within the first few seconds after starting the engine, when the front combination lights perform a self check \(sweep\). - [09\-041\-24](/bulletins/11006899.md), 2024-09-04, Service bulletin: EXTERIOR LIGHTING. Some customers may notice water entry into the front combination lights \(as shown below\). This is due to poor sealing where rain or other water can enter inside the light. To eliminate this concern, the shape of the front combination light has been changed to improve sealing ability. - [SA\-010\-23](/bulletins/10232304.md), 2023-03-03, Service bulletin: ENGINE AND ENGINE COOLING; VISIBILITY; EXTERIOR LIGHTING; SERVICE BRAKES, HYDRAULIC; ELECTRICAL SYSTEM.

Some vehicles equipped with LED or Discharge type headlights may exhibit white milky stains on the inner sur\-face of the headlight lens. Some customers may complain of the poor appearance. This concern is caused by gas that emits from a gasket in the lamp unit. The gas adheres to the inner surface of the headlight lens and reacts with the anti\-clouding coating and moisture in the air to create white milky stains. The gasket material has been improved to eliminate this concern. - [SA390](/bulletins/10185815.md), 2021-01-25, Service bulletin: EXTERIOR LIGHTING:HEADLIGHTS:HIGH/LOW BEAM DIMMER SWITCH.
