[Mr. Kaiser]

Is it common for the rear door piston to go out "all of the sudden"? Our rear door was working fine one time then the next time it does not work. Is there anyway to repair these? Or do I have to buy new? What about a salvage yard? Any luck with these? About how much should I expect to pay?

They are called rear hatch struts. Yes, they do fail and are common. Replace in pairs. Search on "rear hatch struts" for more info. Are you still under warranty?
