A few days after purchasing the truck i noticed one of the ceiling courtesy / map lights was not working and the next time it came on it would be on at half power. it either doesn't come on or comes on at half power. i visited the dealership several times for them to try and locate a new map light. the dealer after several trips told me they couldn't find the needed parts and didn't know what else to tell me. i have contacted ram customer service numerous times as well as the bbb over the past 6 months concerning this problem. ram customer service states there are no parts available to repair my 2013 2500 ram truck which cost $60,000 and they don't know when any parts will become available. one of my concerns is this light must have a electrical short of some sort either in wiring or the light itself therefore may be a fire hazard. ram appears to care less. *js
