Transmission Issues: A Deep Dive

One area where some 2013 Lexus GS 350 AWD owners have reported issues is the transmission. While the GS 350 is generally known for its smooth shifts, problems can arise. One of the common complaints involves rough shifting, particularly when accelerating or decelerating. You might notice your car hesitating, jerking, or experiencing difficulty finding the right gear.
