Yes it has but not to the point of complete shut down. I have had two other issues with the radio over the years. One was a flash issue (?) and other was something with Sirius/XM (that still isn't right).
Unfortunately my dealer is not one that I trust and only go there when I have no other option.
They are always trying to run the bill up instead of helping a customer get things back on track.
One example is the rear sensors. One of mine broke...I asked what the price of one was and they hit me with $380. I just wanted the sensor, everything else is fine. They said you can't do it, have to by a whole rear bumper shroud. I bought the sensor off ebay for $25 shipped and it is fixed. I would have paid $50 for it from them to support my local dealer but no luck.
This dealer, unfortunately is a walk from my house but when I go buy my new Jeep...I will be traveling an hour away.
