So the problem was the spark plugs. They where the original set. Since the body shop paid for everything I also had the induction system cleaned, and the injectors cleaned. For all of that work at the dealer it cost $370.

Wahooo! Goes to show how important it is to change our plugs.
Do yourself a favor next chance you get and check the gap on the plugs. .043 is what it should be.

This exact problem just happened to my 2011 that has 50k on it. I take great care of it, always use full synthetic and do all the other things like diff fluid and transfer case fluid before it even needs it. The plugs were changed out with NGK coppers at 30k. It was towed to the dealership yesterday. I'll keep everyone posted

Hopefully.

But if that's the case, what the hell? Most cars have 100-120k coil packs. These go bad at 50? Owners manual says to replace all of them at 64k.

Well my 09 sat for a long time with the previous owner so I kinda expected issues. I bought it last July with 14.5k miles. It was an expensive 280 for a $40 part.

I pulled one of my plugs this week at 25,000 miles, they are the originals. The burn was clean but the gap has expanded at 0.45, just going to replace them all now and be done with it. I noticed a slightly rough idle when the engine is cold until it warms up a bit, hopefully new plugs set at 0.43 will correct that issue.

The KK's 3.7 is known to just be a little rough.

Verdict:

Small amounts of water down in between the coils and the plugs. Probably from my post-winter wash . . . trying to get all that nasty salt and grime out of the engine compartment. I thought that a vehicle made to ford 20" of water would have everything under the hood nice and water-resistant. I was wrong. They cleaned up the mess and got it running again. $100 bucks
