The side mirrors have spider cracked from some type of electrical issue. This is the 2nd time this happened and it burns both mirrors at the same time. The mirrors become unusable and it appears the dealer replaced them under warranty the first time and the second time they said it is out of warranty so I had to pay out of pocket.

While driving both drivers and passenger side blind spot warning lights flash on and off when no cars are near. The problem is worse at night when pulling a trailer. The lights sometimes stay on or starting flashing on both side causing a significant distraction.
