Both left and right aluminum uprights or commonly referred to as “knuckles” are cracked. This can cause an immediate loss of control at speed and also take out the cars around you. This is a very serious problem. Apparently, other models years have previously been recalled. But the 2017 model year has not. Clearly the same issue and the cracks are in the same place. There are no warning signs of such cracking in the upright. But when it fails, it will render the driver useless until inertia takes over!
