Why gm makes the worst pickup trucks

In this video, the creator provides a 15,000-mile review of his 2025 GMC 3500 Sierra with a 6.6L gas engine (0:01). He discusses some intermittent surging and transmission issues (0:33) that the dealership claims cannot be duplicated (0:48). He also notes the poor wear of the Michelin LTX AT2 tires (1:17) and the dealership's refusal to warranty them (1:40).

The video then follows the creator on a trip to the scrap yard, where he hauls nearly 5,000 lbs of scrap metal in his dump trailer (2:22). He highlights a reoccurring "trailer disconnect" issue (2:56) with the truck's trailer plug, which he believes is a wiring problem (4:17). During the trip, he monitors the truck's fuel economy, noting an average of 11.8 MPG over 450 miles with towing and idling (6:11), and 8.8 MPG during the scrap yard trip (13:33).

He also shows the truck's ability to power up a steep 12% grade hill while towing approximately 8,500 lbs (10:50). The video concludes with the truck weighing in at 16,300 lbs loaded and 11,620 lbs unloaded at the scrap yard (12:44), demonstrating its towing capability (13:15). The creator expresses hope that the transmission will withstand the towing demands of a one-ton truck (14:06).
