2011 Hyundai Santa Fe: engine knocking or ticking

Filed Apr 9, 2026 · Engine, Transmission · TX

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 the federal safety agency 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.

We have (had) a 2011 Hyundai Sante Fe. On 9/21/21, driving to Bozeman, just west of Livingston MT, on I-90, the car had a sudden stalling, loss of power (check engine light, oil light came on), then knocking sound that increased in volume and frequency. Smoke began pouring from under the hood as we pulled to the side of the highway, then very quickly accompanied by flames. We exited the vehicle. I opened the hood, the flames shot into the air. We moved away from the car. 911 had been called and the local fire department arrived within 10-15 minutes. Fire extinguished after about 20-30 minutes, but engulfed (destroyed) the entire engine compartment. Flames did not spread to passenger area of the vehicle. No one injured from the fire (although possible smoke inhalation before and as we exited vehicle). Car totaled, towed from highway. 1. Component: engine, all components in engine compartment (available for inspection, see photos uploaded); 2. Safety threat: smoke, fire quickly engulfed engine compartment, threat of spread to passenger area of vehicle; 3. Not yet confirmed by dealer or independent service center; 4. Inspection: by police/fire department that responded to the incident indicating mechanical malfunction, without further detail; 5. Warnings: check engine light and oil light occurred prior to or at time of incident and before severe knocking sounds began, but at same time as stalling/power loss.

While driving about 35mph a fast ticking sound came from the turn signal/steering column area then it started smoking so I turned on the turn signal and it stopped ticking I almost panicked. Incident has happened 2 more time's but I put on the turn signal quickly before it overheated and it did not smoke. The car has not been to a service center or dealer and there we no warning lights on or prior symptoms

Nothing has happened so far, my complaint is that every 4-6 months, I need to buy parts for my santa fe. It starts with a knock on the right front end of the car. I need to get to work, so I take my time getting there. I also was about to get on the highway, and the spring broke on the on ramp. I see all the horror stories about this model hyundai with issues with the front end . I can send you repair bills of what parts have been replaced over the last 5 years.
