Vehicle had issue resolved by recall p57 where key fob would stick in ignition between off and on. The key first got stuck in the ignition on 8/14/14, a memorable day, because it happened on the day we were going to the title company to close on our first home. At the same time the ignition switch issue started the airbag light came on and all the steering wheel functions are disabled. The horn no longer works. It is unknown if the airbags work. This is clearly a safety issue but the dealership wants to charge $90 just to hook the vehicle up to their machines to diagnose what is going on and will not consider this as related to the recall p57. Not being able to honk in the interest of safety is a problem. It is unknown if the airbags are functional so I guess it will take getting in an accident to find out (an accident which cannot be prevented by honking my horn to warn another driver).
Electrical problem: liftgate open- indicator problem alarm on car has triggered several times and inside indicator light on dash says liftgate is open. After checking and closing - message does not end. Upon driving vehicle all interior lights are on, day or night. On locking with key fab vehicle horn does not sound as it usually does. Alarm not set. Precursor of more serious electrical problem???.
