When accelerating into a turn from a complete stop, left turn or right turn, there is a knocking sound coming from the cv joint. Vehicle made this sound when driving off the lot brand new. Vehicle also experienced a battery fault error/reduced propulsion warning at 700 miles and is currently at the dealer to investigate. The error alternates with the battery fault light indicating a fault with the high voltage battery and the propulsion power is limited light. This error occurred after preconditioning at 30% battery charge in 32 degree weather. The vehicle warmed up the interior but displayed the message as soon as I put the car into reverse gear. Both of these issues are safety issues in potential loss of steering and loss of propulsion power on the road.
