What owners wrote

“The high and low beams quit working while driving at night. This caused safety issue for myself and other drivers. Fuses good and bulbs good. Have seen multiple listings online about the same thing happening to other owners.”

“The headlights are dangerously dim, can't drive the vehicle comfortably at night. There seems to be no solution for fixing them. A TSB has been issued concerning this, but does little to address fixing the problem.”

“Both headlamps stopped working when driving at night. Neither the low or high beams will work”

Should you keep driving it?

This page can't tell you that. 1 of 104 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
