“Key fob disconnects while driving. Lock/unlock does not work. Car does not start when keyfob is in vehicle. This has happened three times now, the dealership has changed my keyfobs, flashed the memory, and replaced the batteries. I've spoken to corporate customer service and was told sometimes key fobs just disconnect. Please exit the vehicle, wait, and try again. I'm currently waiting for this to happen a fourth time.”
