Infotainment system freezes causing battery to drain to zero when parked. Radio stops, navigation stops, phone stops working, backup camera stops working. Evidently a common problem because class action suit filed in March in California. Took to dealer, theye changed battery, told me it was fixed. Froze again the next day. Vehicle was in motion when system failed. The next morning car would not start because battery drained. This was on a federal highway. Happened again after the battery was changed.
