Rear taillight assemblies x 4 {left and right trunk hood assemblies and the outer turn signal/brakelight assemblies) have pooling of water and condensation/debris buildup inside the lens covers. Also noticed condensation and liquid buildup within the license plate illumination lenses. Very concerning as these are electrical components that are contained near the high-voltage lithium battery contained within the trunk space.
