I bought my 2016 Promaster 1500 used with 19,000 miles. The day I went to pick it up the front headlight bulb was blown... So sales guy changed it on his own. He went to autozone and all was good. After a few weeks the same bulb fell out again, won't stay in. A few weeks later other bulb falls out. I take to dealer for warranty and they said they can't cover because non factory bulb and the bill is $720. I explain its that way because the sales guy changed bulb because it was blown and that it doesn't explain the other side. Their mechanic said "that's what happens when you put them in wrong". So I say to the warranty lady "Why does a 2016 need multiple bulb replacements?" I'm now awaiting a call but anyone had a problem with their bulbs falling out of the headlamp? I have literally seen 2 Promasters on highway where I could see that their bulb had fallen out and I thought it was my van!
