My 2011 Hyundai Santa Fe (approx. 153,000 miles) developed a new stalling and engine-dying-at-idle condition immediately following a knock sensor replacement performed by a Hyundai dealership. Prior to this repair, the vehicle ran normally with no stalling or idle issues. The vehicle was originally brought in for diagnosis related to code P1326, which is covered under Hyundai Service Campaign T6G (engine rod bearing / knock sensor campaign). The dealership replaced the knock sensor but subsequently claimed my vehicle's P1326 condition did not qualify under Campaign T6G. Immediately after the knock sensor replacement, the vehicle began stalling and completely shutting off at idle — a condition that did not exist before the dealer's service. I returned the vehicle to the dealership to address this new issue. The vehicle has now been at the dealership for over three (3) weeks with no diagnosis update, no repair timeline, and no communication from the service department. I am filing this complaint for two reasons: 1. Safety concern: An engine that stalls and dies at idle presents a serious risk of loss of vehicle control, particularly in traffic or at intersections. 2. Service Campaign T6G: I believe the underlying condition and the dealer-caused stalling issue are both connected to the knock sensor system covered by this campaign. I request that NHTSA review whether this vehicle qualifies under Campaign T6G and whether dealer-caused damage following campaign-related service should be addressed under the campaign or a related recall. The dealership's failure to communicate for 3+ weeks and their claim that my vehicle is not covered under Campaign T6G warrants regulatory review.
