The driver's side sun visor internal cam broke while vehicle was being driven such that the sun visor hangs at the lowest point, and is no longer adjustable. This obscures the driver's field of vision when driving the car and thus presents a safety hazard. This appears to be a common defect in the sunvisor design/manufacture based upon identical user forum reporting. Subaru America refuses to acknowledge responsibility for this defect in design or materials workmanship.
Driving in rain with windshield wipers on. Wipers crossed and made a "x" then twisted and malfunctioned.
Windshield wipers sometimes stop working and get caught up in each other, the bolt need to be tightened many times, has almost caused multiple accidents.
Serious windshield wiper failure of entire linkage system caused by a hold down nut coming loose from main linkage. My wife was driving on the highway during a rain storm when both windshield wipers failed. She narrowly escaped an accident as there was no place to safely pull the vehicle over and she lost total visibility. The 2008 Impreza outback sport was taken to a nearby Subaru dealer where they fixed the problem by simply tightening the hold down nut which came loose. Needless to say, I was very disappointed by this serious safety issue from a new car that was rated this top safety pick. The car had 9800 miles on it when this incident occurred.
The contact owns a 2008 Subaru Impreza. The contact stated that the windshield wipers will periodically stop working and fail to move altogether, even when they are in the upright position. He must pull the vehicle over and manually pull the wipers down with his hands. The failure has occurred over ten times while driving 20 mph. Most of the time the wipers work normally, but during rainy and snowy conditions, the failure can cause poor visibility. The Subaru dealer could not determine the cause of the failure. The manufacturer stated that if the dealer could not find a failure, there was nothing to repair. The current and failure mileages were 10,000.
