09-006-242024-03-06. Service bulletin. STRUCTURE:BODY:HATCHBACK/LIFTGATE; LATCHES/LOCKS/LINKAGES. 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.

Some customers may experience a “Telematics Malfunction” message in the instrument cluster with DTC U3000:04-TCU (Telematics communication unit internal malfunction) stored in memory. This is caused by improper control software of the telematics communication unit (TCU). To eliminate this concern, the control software of the TCU has been modified.
