BMW 1.16 (F20) ED Window Sealant And Taillight Malfunction

Hello, I hope you're having a good day. I'd like to address issues with my 2014 Model 1.16 ED vehicle. The right rear taillight is less illuminated compared to the left side. This problem has been consistently reported by owners of 1.16 vehicles from 2012 to 2015 across various platforms. Furthermore, the windshield wiper of the same vehicle is deteriorating, resembling the disintegration of a sponge. This issue is chronic and has been raised on multiple platforms related to BMW vehicles for the 1.16 model from 2012 to 2015. I am seeking a solution and reparation for these recurrent issues.
