   There are these "New" headlights that are LED and White and they are far to bright for oncoming traffic to the point that I see black spots that block the view of the road. To be clear they are not on my vehicle specifically, but a ton of the newer vehicles.

   My 2018 Chevrolet Colorado diesel has had repeated diesel emissions/DPF-related failures that cause the vehicle to enter reduced-power or limp mode. This is a safety issue because the truck suddenly loses power and cannot accelerate normally. The most serious incident occurred while driving over Santiam Pass in Oregon.
