When accelerating from a complete stop (especially onto an incline) the engine RPM increases but the vehicle fails to accelerate as expected. The vehicle jerks and shakes violently and is unable to gain speed.  This issue is intermittent but highly repeatable and occurs almost every time when there is a slope immediately after a stop sign. It results in loss of acceleration, violent shaking, and inability to maintain or build speed, creating a serious safety risk in traffic.  It first happened around 1 year (early 2026) after the new car purchase (Nov 2025). There are no warning lights or messages. The dealer claimed they were unable to reproduce the issue during a brief test drive without me present and incorrectly attributed it to a bulletin without performing a detailed diagnosis or repair or looking at the video we recorded on the issue. The issue persists and affects safe operation of the vehicle. No inspection has been done by police or insurance.  In one instance, this occurred while other vehicles were approaching from behind, creating a dangerous situation where I could not accelerate to match traffic flow. This resulted in a high risk of being rear-ended due to the unexpected loss of acceleration.  I am aware of other consumer reports describing similar transmission-related symptoms such as slipping, hard shifting, and hesitation in this model. Some complaints describe transmission issues occurring at low mileage without warning lights.","products":[{"type":"Vehicle","productYear":"2025","productMake":"GMC","productModel":"ACADIA","manufacturer":"General Motors, LLC"}]}]}
