A few months ago the dealer replaced a rear tail light assembly due to moisture issues. The moisture caused a short which impacted blind spot, rear traffic, tire pressure monitoring, restraint control and cross-traffic systems. The replacement assembly solved those issues. Since that time I have been having issues with the automatic tailgate - it likes to open on its own, sometime triggered by opening the drivers door or locking the car. The signal is often sent multiple times so there is nothing you can do to close the tailgate until it stops. The tailgate has opened randomly on the highway too - key sitting undisturbed in the cup holder. Has anyone had similar issues? Dealer is 10 days out for an appointment. Any thoughts, suggestions are appreciated.
