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.

Loss of Motive Power
the federal safety agency received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitionersâ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODIâs evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to the federal safety agency which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing. Â There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in the federal safety agency's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, the federal safety agency does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing the federal safety agencyâs reasons for denial of the petition will be published. The reference numbers for the complaints to the federal safety agency cited by the petitioner can be found in the petition submission documents in the public file for DP22-003.

What 2011 Hyundai Santa Fe owners say
Most recent owner complaints, unedited.
CATASTROPHIC ENGINE FAILURE. With no prior indications, the engine seized while driving on side street at 25mph. Engine blew hole in block and dumped engine parts, including piston rod, piston and engine block remnants, and oil on street. Very dangerous as power steering stopped and was unable to turn. Very low miles, 40,680, with all maintenance performed by dealer. Filed a report with Hyundai USA, no action taken.
The contact owned a 2011 Hyundai Santa Fe. The contact stated while the contact's daughter was driving at an undisclosed speed, the contact noticed a burning odor and the vehicle stalled. The contact idled the vehicle to the shoulder of the road and exited the vehicle. The vehicle burst into flames after the occupants exited the vehicle. The contact's daughter and daughter's friend were occupants of the vehicle at the time of the failure. No injuries were sustained. The fire department arrived and extinguished the fire. A Police report was filed. The vehicle was towed to a local tow yard. The vehicle was condemned to total loss. The manufacturer was made aware of the failure. The failure mileage was approximately 280,000.
The contact owns a 2011 Hyundai Santa Fe. The contact stated that on six occasions over 12 months, the vehicle overheated while driving at various speeds. Additionally, the contact observed white smoke coming from the exhaust pipe on the rear passenger’s side and the front of the vehicle. The check engine warning light was illuminated during the last failure. The contact stated that on several occasions the vehicle was taken to the residence, and on other occasions, the vehicle was towed to an independent dealer where it was diagnosed that the thermostat housing and radiator needed to be replaced. The vehicle was repaired but the failure reoccurred several times. The manufacturer was not notified of the failure. The failure mileage was approximately 135,000.
The contact owns a 2011 Hyundai Santa Fe. The contact stated that while driving at an undisclosed speed, the charger indicator warning light illuminated and the engine seized. The battery was recharged. The vehicle was taken to an independent mechanic where it was diagnosed with a failed valve cover gasket leak and that the valve cover gasket and the alternator needed to be replaced. The vehicle was not repaired. The vehicle was scheduled to be taken to the dealer for inspection within the week. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 126,600. The VIN was unavailable.
I was driving the car on a 4 lane road when suddenly the engine shut off and the car was no longer functioning. I lost power steering and had to coast into a nearby parking lot, otherwise I would have caused a major accident in the middle of a busy intersection with another 4 lane road. Upon taking the car to Hyundai for evaluation, it was declared to be total engine failure. Given the other issues with Hyundai engines failing and the fact that I VERY NARROWLY AVOIDED A MASSIVE COLLISION, I would like the federal safety agency to be aware that this problem may go back farther than Hyundai has addressed so far.
My 2011 Hyundai Santa Fe had 75,000 miles on it in September 2022. It was bought and serviced by the same dealership and I am the original owner. It was last serviced at the end of June 2022. While returning from Corvallis, Oregon to Forest Grove, Oregon, the car's display light all turned on and a second late the car completely stopped. I am thankful that I decided to take the back road home, if I had been on the highway, I am positive I would have been in a serious accident. It has been determined by the dealership that there was a complete engine failure. It has been at the Hyundai dealership for four months now and there is no replacement engine available for it. Not only that, they can't get a reasonably priced replacement engine anywhere. This car would have been a valuable trade in on a new car. The Diagnosis was Engine crankshaft seized. Metal particles on Dipstick, large metal fragments on oil filter, Engine replacement required. The car is now worthless, expect for parts.
UNKNOWN warning I’m the owner of a 2011 Hyundai Santa Fe and a week ago at 185k mikes all of a sudden driving on the freeway it started hesitating and sounded like metal grinding and smoking really bad. Pulled to the side of the freeway on a ramp at that. Tried to restart the vehicle and I heard a bang noise which upon later discovery the engine blew a rod with no warning locked the steering wheel couldn’t get the keys out of the ignition DO NOT buy this car still owe 5k on the vehicle
Engine stalls
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.
