My 2014 GMC Sierra 1500 SLT has terrible headlights. If you set the low beam such that you can see more than 150 feet in front of the vehicle then the high beams are pointing up in the tree tops. There would be early adequate light that the bulb selector relationship is wrong and can’t be adjusted. I installed LED headlights so at least I can see a bit better on low beams. GMC is unable to offer any solution.
These lights on a $55,000.00 vehicle are unsafe – period.
It does not matter how good anything else is, I won’t be buying a fourth GMC Sierra SLT.
