“The headlights are failing, new lamps does not resolve the issue. Bad design, the inner reflective housing has melted and the lamps no longer light the road correctly. New lamps did not resolve the issue. I am having to replace the whole lamp housing at over $600 per side just to enable me to drive at night. Very dangerous situation”

“Vehicle headlights are very dim and night visibility is extremely limited and very dangerous. Driving in rain proves impossible. Seems to be a known issue that Cadillac owners are repairing themselves to the tune of between $1400-3000. Models SRX, years 2010-2016 After reading many user/enthusiasts web forums, I see this issue being reported by hundreds of owners.”
