Head Rest Keeps Sliding Up

I know this is a first world problem, but my 23 platinum's drivers seat head rest keeps going all the way up when I want it down. I'm only 5 7". The picture shows it only starting to creep up but on long drives it will eventually make it all the way extended.

Do you think it's worth asking the dealer to take a look at it. My truck has 20,000 miles on it.

 

Yes, of course, why not have the dealer take a look?

 

I'm not sure something so trivial would be coverable.

 

Mine dose that.

 

On my next trip for oil change I'll report the problem and we will see what they do. My 22 Tacoma did it as well and I just accepted it. This time I'm going to try and get it fixed. I'll let you know.

 

Mine does it too.

 

Maybe you are getting shorter ?
