Wheel Related Problems of the 2026 GMC Yukon

Wheel problem

I am submitting supplemental information regarding complaint #11716907 involving a 2026 GMC Yukon xl at4 equipped with the brembo brake package. Following my original submission, gm's executive resolution office provided written clarification of its disclosure position. Gm states that the spare tire compatibility limitation associated with the performance brake upgrade is disclosed through a hang tag affixed to the spare tire/wheel assembly mounted beneath the vehicle; and the owner’s manual. Gm has not indicated that this limitation appears on the monroney label, buyer’s order, or delivery documentation. The hang tag provided to me as an example states that the original spare tire/wheel does not fit the front axle when the performance brakes are installed. It instructs that, in the event of a front-axle flat, the consumer must install the spare on a rear wheel position & move a rear wheel to the front axle; and stow the flat tire. The spare tire is mounted underneath the vehicle. The tag is attached to the spare assembly and exposed to road conditions. In my case, when the spare was accessed following a roadside flat tire event, only a small piece of yellow plastic remained. Additionally, no printed owner’s manual is provided at delivery. During my roadside event, the dispatched service provider was unaware of any two-wheel rotation procedure and attempted to install the spare directly on the affected axle. The incompatibility rendered the spare unusable at that time. My concern is that current owners of vehicles equipped with the performance brake upgrade may reasonably assume that a “full-size spare” is compatible with all wheel positions. Unless the undercarriage hang tag remains intact and is specifically read at the time of a flat tire, the incompatibility and required rotation procedure is not apparent. Gm has not indicated it intends to notify new or existing owners regarding the spare tire limitation and required rotation procedure.
