Intermittent drivability issue involving the transmission during takeoff from a complete stop, most noticeable in heavy traffic and stop and go conditions. Vehicle shudders and lurches when accelerating from a dead stop, with a sensation similar to being hit from behind followed by abrupt engagement. This creates unpredictable launch behavior and raises concern for safe acceleration in traffic, including potential risk when entering intersections or merging. In addition, vehicle has a recurring squeaking noise on cold start that sounds like a belt or pulley related issue. Also experiencing an HVAC airflow malfunction where the center dash vents initially blow air, but within about 30 seconds the center vents stop and airflow shifts to lower vents and or upper dash vents only, affecting normal climate control and potentially defogging or visibility depending on conditions. Issue has been reported to authorized service centers, but the transmission concern has been difficult to duplicate and remains unresolved.
