Unfortunately that is correct. I had both of them replaced. I paid for the first but threw a fit when the other one went out so the dealer picked up the cost. There is circuit board in the lense and one connection for all of the lights. It is not really a circuit board per se but a bunch of tracer circuits going to the bulbs. This is a known issue.

If you have a digi cam take some pics for us. My schematics dont mention a board but the diagram kinda hints that there is one. (it should of said so) You might be able to pop these things apart and rebuild them
replaced a total of 7 times in 4 years. The cause: Printed circuit board assemblies in the tail lights CAN'T handle the current load and melt the plastic assembly. Five were replaced under warranty. We have paid for the last two at $182 each and it needs ANOTHER right rear light along with a new engine!"
