SA-039/25	2025-09-05. Service bulletin. Some vehicles may experience exterior trim heat damage such (melted, separating, etc.) when parked near a glass building or Low-E windows. This may be caused by the sun's reflection. If a structure's windows create enough of a curve, the concave glass can focus the sun's rays onto a small area and acting like magnifiying glass direct the sunbeams into a hot pinpoint of light. This magnifcation of the sun's rays can cause damage to vehicle trim (see examples). Additional information and exemplar images regarding this phenomenon can be found by performing a google search.

SA-056-24	2024-09-04. Service bulletin. Interior parts made of resin have antistatic coating to prevent dust from sticking on the surfaces, and depending on the conditions of use, the antistatic components may crystallize slightly, giving an appearance of white stains on the surface. To remove the stains, wipe the stained surface with a towel soaked with water mixed with a small portion of a neutral detergent. If the white stains reappear again, simply wipe them again in the same way.
SA-050-24	2024-09-04. Service bulletin. Some customers may complain that their liftgate does not open. This can mean a range of things, from the liftgate not unlatching to the power liftgate (PLG) not opening automatically. If you confirm that the customer's concern is that the liftgate does not unlatch correctly, follow the repair information below.
09-006-24	2024-03-06. Service bulletin. Some vehicles may exhibit a creaking or clacking noise when operating the power lift gate (PLG). The noise may be caused by the following: Creaking noise: Dust and dirt accumulates on the sealing portion of the PLG drive unit, reducing sealing performance. Snow and water may enter the PLG drive unit. Humidity then causes rust inside of the unit, resulting in noise. Clacking noise: Since the grease applied on the spring end of the PLG drive unit is insufficient, interference noise is caused when the spring end interferes with the spring guide. The noise has been eliminated by the following mass-production changes: Creaking noise: The sealing structure has been modified to prevent dust/dirt from entering the unit. Clacking noise: The production procedure of the PLG drive unit has been modified to apply sufficient grease to spring end.
