What owners are reporting 1 most recent
I purchased this vehicle december of 2014 and within a month I noticed condensation in both headlights. When I was driving my vehicle home one night with my 4 children the lights flickered and went out. I had to pull over and I flicked the lights on and off hoping they would turn on and they came back on and worked. Now either headlights work and to replace the assembly is $1600 each so right now…
