Tow package contents
The 2015 GMC Acadia offered a factory trailering package (V92) that included a heavy-duty cooling system, a factory-installed Class III hitch receiver, and a 7-pin wiring harness. Unlike heavy-duty trucks, it did not include an integrated trailer brake controller from the factory; this would need to be added as an aftermarket accessory for trailers equipped with electric brakes.
Weight distribution & WDH requirements
For trailers over 2,000 pounds, a weight distribution hitch (WDH) is recommended to maintain vehicle stability and reduce sag in the rear suspension. A WDH helps to distribute the tongue weight of the trailer more evenly across the axles of the tow vehicle and trailer, improving steering control and reducing sway.
Real-world towing tips for this vehicle
When towing with a 2015 GMC Acadia, it's important to keep the vehicle's unibody construction in mind. Unlike body-on-frame SUVs and trucks, the Acadia is not designed for heavy-duty towing. It is crucial to stay within the recommended 5,200-pound limit and to use a weight distribution hitch for heavier loads. Activating the vehicle's Tow/Haul mode will adjust the transmission's shift points to hold gears longer, which helps to reduce heat buildup and improve performance when towing.
Common towing-related issues
The most common towing-related issues with the 2015 GMC Acadia are transmission overheating and premature wear on the rear suspension components. The 6-speed automatic transmission can be prone to overheating when towing heavy loads, especially in hilly terrain or hot weather. Using the Tow/Haul mode and ensuring the heavy-duty cooling system is functioning properly can help to mitigate this risk. Additionally, towing heavy loads without a weight distribution hitch can put excess strain on the rear shocks and springs, leading to premature wear and a sagging rear end.
