NHTSA Complaint #11441861 — 2014 CHEVROLET SILVERADO 1500

My vehicle's headlamps are so dull I can't see at night. I contacted GM and they offered to replace them if I would pay half the cost , which I was going to do , but I had a heart attack and surgery & was in intensive care for almost a month. When I became able to come home , after I missed my appointment due to this situation , I contacted GM and they said they were not going to help me because I didn't have it done in time. My vehicle is always parked in a garage and well kept. The headlamps are VERY dull and dangerous to drive at night. I would like Gm to replace them as I believe this is a manufacture's defect. I was a GM Dealer for several years and don't believe this is their usual practice , giving them the benefit of the doubt. These are dangerous as I can't see at night and oncoming traffic can't see me either clearly. Please help me. This is DANGEROUS!
