09-023-20-37232020-08-04. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; STRUCTURE. Some vehicles may exhibit a deformed fuel-filler lid panel (1) attached to the fuel-filler lid box, resulting in a poor appearance. This concern is caused by the lid box not having enough water drainage capability which leads to the accumulation of water inside it. The water then freezes in cold weather and expands or the inner side of the lid panel absorbs the water and swells from long exposure, deforming the lid panel. To eliminate this concern, the shape of the fuel-filler lid box has been modified to have better drainage capability.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
