What owners wrote

A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

I hit an elk at 65 mph while pulling a flatbed trailer loaded with 4000 lbs of hay. The crash warning light did not come on nor did the air bags deploy. The whole front end of the truck is badly damaged. I contacted my local Ford dealer with this information and was told by the service agent that the body shop will handle this. As my concern is how hard do you have to hit something to get the airbags to deploy. I’m concerned for my safety while driving this truck again if it can be repaired.
