NHTSA Complaint #11716802 — 2021 CADILLAC XT6

Cadillac XT6 – VIN: [XXX] echanical Failures, Ignored Transmission Recall(s), and Dealer Negligence I write this letter to formally place General Motors Company on notice of a pattern of serious mechanical failures, ignored safety recalls, and dealership indifference involving my Cadillac XT6, referenced above. This vehicle has been presented to Sam Leman Cadillac of Champaign on multiple occasions for mechanical issues, including—but not limited to—cooling system failures, thermostat defects, persistent check-engine warnings, and abnormal vehicle operation. Service records confirm repeated interventions, temporary fixes, and diagnostic acknowledgments without meaningful long-term resolution. More alarming, however, is the dealership’s failure to appropriately address and disclose known transmission recalls and other safety recalls applicable to this vehicle. Despite GM’s documented awareness of widespread transmission issues affecting similarly situated vehicles, the dealership elected to either minimize, ignore, or defer corrective action—placing convenience and cost avoidance above consumer safety. This conduct raises serious concerns, including: •Failure to act on known manufacturer defects •Failure to honor GM’s recall and safety obligations •Repeated return of a vehicle to service despite unresolved defects •A pattern of repairs that suggests systemic failure, not isolated incidents •Improper shifting of financial responsibility to the consumer for manufacturer-caused defects Consumers do not purchase Cadillac vehicles with the expectation of serving as unpaid beta testers for unresolved engineering flaws. Nor should they be forced to navigate a maze of denials and deflections when defects arise that GM already knows exist. This is not a maintenance issue—it is a manufacturer and dealer accountability issue.
