When the rear shade wouldn't retract, I tried seeing if I could manually retract it at the motor. No luck.

The motor and its linkage were too tucked down into the rear cowl for any easy access.

After contacting the dealer and getting the service estimate, we decided it was not worth the cost of repair.

My wife had no trouble with it (her car, only driven in the daytime), but I found it unsafe in night driving because it created blindspots and reduced rear visibility. This was our first problem with the car.
