Issue may be due to the brake failure sensor.

what is the brake failure sensor and where is it located at?

 

Refer to the link threads in my previous post.

 

As a side note, once you resolve the "failure" sensor issue.....it might not hurt to "re-seal" the right rear taillight.

There is a seal between the taillight and body that will leak over time and allow water to get into the light/trunk. Water and electronics (failure sensor) do not get along that well
