There are 1 owner-reported lighting complaints for the 2018 GMC Yukonin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Headlights are terrible. Driving at night is treacherous because the headlights are not very bright unless I can use brights which seems like they could be low beam instead of high beam. With oncoming traffic it is hard to see the road and I get scared it may cause an accident, either hitting an oncoming car or going off the road myself. It's terrible. Others have commented on the headlights also asking me how can I see. There is no film on the covering over headlights. I Can see the bulbs just fine but they look burnt. My husband thought so too. Just scared driving at night. Need better Headlights!
