At speed, the vehicle experience "steering wander" regardless of the road surface. Required constant inputs to keep the car tracking straight. Dealer, (Of course), found no issue. Took the car to the local Tire Store who found no issues with alignment or tires, but noted these are SUV tires!! Battery Died. Not sure of the components surrounding this issue, but the car while stopped, in drive, started bucking somewhat violently like riding a mechanical bull. Crazy. Dealer blamed in on battery! Air conditioning could not keep the interior cool with an outside temp of 85 degrees. The automatic mode was a joke and used manual control with a set point at 65 degrees and the fan on 3/4 speed.
