Oddly enough I have the opposite problem. My 19 limited's tailgate kept opening while driving. The other day, the tailgate opened on it's own while pulling my trailer. Now it's all me
ssed up. Dented, paint damage, etc. The reason I say my problem is opposite from others specified above is that not once did a "tailgate open" warning show. I didn't even realize that the truck had one. In fact when I went to the dealer about the issue I mentioned in talking to the service manager about the damage that I thought it weird that with all the bells and whistles the truck has I was surprised that it didn't have a tailgate open warning.
