One problem related to wiper has been reported for the 2015 Lexus IS350. The most recently reported issues are listed below.
My car was in parking structure when I walked out to my car for lunch, opened car door and noticed glass shards on center console. Looked up at sunroof to find that it was completely shattered. Looked over vehicle to see if some object had fallen on top of vehicle, but after noticing that glass sunroof was intact & bubbled upward, it became clear that glass had shattered (I. E imploded) from within the vehicle.
