Have a 2015 Tahoe LT 4wd with 25k miles on it. Been driving fine until tonight. Stopped for gas and when I drove out from station, while turning sharply at slow speed, the wheels locked up like brakes were engaged. Drives ok straight, but when making a right or left turn (forward and reverse), the car comes to a stop like brakes are pressed. Have to straighten wheel and give gas to move forward again (because it won't move while idling in gear) Any ideas what might be happening?
Thanks!
Mike
