Wheel Related Problems of the 2026 GMC Sierra 1500

Wheel problem

In early June 2026 I discovered a sheared pin on the front control arm of my 2026 GMC Sierra 1500 at4x (VIN [xxx]), sold to me new by parks GMC, kernersville nc, with a dealer-installed performance package modifying the factory suspension. I delivered the truck to parks GMC for warranty repair. The dealer represented it as a 1-2 day job. The truck was out of service approximately 2 weeks. The dealer sub-contracted the work to a third-party shop (ccv). At pickup, the dealer provided written documentation stating the repair was not performed. Neither the dealer nor I has been able to obtain any documentation from ccv describing what, if anything, was actually done to the vehicle. Three unresolved safety conditions: sheared front control arm pin — original failure, status of repair unknown and undocumented. Tire-to-bodywork contact — front tires intermittently rub the inside of the wheel wells during normal driving and steering, causing visible damage to the plastic mud guards. Tire-to-bodywork contact creates risk of sidewall failure, sudden air loss, and loss of vehicle control. Front right suspension creak — loud, persistent creak from the front right suspension during low-speed driving and steering inputs. Present at service drop-off, never addressed. Consistent with a worn, loose, or improperly installed suspension component. I escalated to parks GMC management and GMC customer assistance. Parks has not provided a written repair plan, no decision-maker has contacted me, and the only response has been "looking into it. " GMC customer assistance declined to assign a district service manager. I am filing to document these suspension and tire safety conditions in the federal database against this VIN and to request NHTSA evaluation of whether further action is warranted.
