2013 Hyundai Santa FE Sport engine problems

ENGINE

I was driving down a highway and was slowing down as motorcycle in front of me was turning. I than proceeded to drive, I heard a loud noise which everyone in the vehicle thought it was the motorcycle (it wasn't) we pulled over into the nearest gas station and saw that my oil light was barely blinking (it was barely noticeable) was fading in and out) we got out checked the dipstick and it was low. Was not due for an oil change for another 1500miles. We put oil in and waited checked the dip stick it was then reading between the two lines of L and F. We waited another 5-10 minutes before leaving. We pulled out and the vehicle acted as if it had no power. I pushed on the gas to get up to speed and the car died out; I got pulled over to the side of the road. The car gave me no indication of anything. No oil light. I drove the days before with no issues I was 38miles from home.

ENGINE

My 2013 Hyundai Santa Fe Sport is subject to Hyundai Recall 162 / NHTSA Recall 17V-226, concerning premature connecting-rod-bearing wear that can cause engine knocking, engine failure, and loss of motive power. My vehicle developed engine knocking and a flashing check-engine light while I was driving. The vehicle is now at an authorized Hyundai dealership. Hyundai initially denied an engine replacement based on mileage. I escalated the matter to Hyundai Motor America Corporate Consumer Affairs. Hyundai has now confirmed in writing that, because my vehicle is more than eight years old and has more than 150,000 miles, Hyundai is applying the high-mileage provision of the Theta II settlement and will not replace the engine. Instead, Hyundai is offering either a repurchase or $2,000 in lieu of engine replacement. I understand that Hyundai is relying on the court-approved settlement. My concern is specifically whether Hyundai’s application of that settlement to my vehicle is consistent with the administration of Recall 162 and the federal safety-recall remedy, given that my vehicle is experiencing the engine failure that Recall 162 was designed to address. I am requesting NHTSA’s review of Hyundai’s handling of this safety-related recall matter.

ENGINE

Vehicle is a 2013 Hyundai Santa Fe Sport with the 2.4L Theta II GDI engine. A Hyundai dealer documented excessive oil consumption in December 2025 (3 quarts consumed over 1,703 miles during a dealer-administered oil consumption test; repair orders on file and available for inspection). On April 19, 2026, at 160,913 miles, following a highway drive, the engine developed a pronounced knock and vibration at low RPM and began stalling within seconds of idling in Park, with check engine and charging warning lamps illuminated. An engine that stalls at idle presents a safety hazard in traffic due to loss of power braking and steering assist. The vehicle was removed from service the same day, has not been driven since, and remains available for inspection. Knock Sensor Detection System software (Campaign 953) was installed and did not prevent the failure. Manufacturer has been notified in writing and consumer affairs cases are on file.

ENGINE

Issue was first identified in September 2024 when a rattling noise prompted inspection, and the engine was found to be significantly low on oil. Excessive engine oil consumption was confirmed with failure during manufacturer testing. Vehicle emits occasional burning oil smell when idling after 10 miles+ driving. Vehicle failed a 1,000-mile oil consumption test following a “Dynamic Engine Clean” performed by a certified independent mechanic, with documented oil loss of approximately 2 quarts. Vehicle subsequently failed a dealer-administered oil consumption test, with documented oil loss of approximately 2.3 quarts within 1,000 miles. Engine oil levels have dropped to critically low levels between checks despite active monitoring and maintenance. This condition presents a risk of engine seizure, sudden loss of power while driving, and potential engine compartment fire due to oil consumption or leakage. The issue has been reproduced and documented by both an independent mechanic and a Hyundai dealership. Despite confirmed excessive oil consumption, the manufacturer has delayed corrective action and has required repeated oil consumption testing and engine cleaning procedures rather than proceeding with repair. This condition appears consistent with known defects associated with Hyundai Theta II engines.

ENGINE

I noticed a Check Engine Light flashing on my dashboard while driving on May 27, 2026. The vehicle suddenly losing power is extremely unsafe for me and my family, and also others on the road. This is a repeated P1326 code which happened before in 2021 and 2024. Based on the receipts I have from the previous inspections from the dealer, the Bearing Clearance Test (BCT) was not done in 2024, but was performed in 2021. The knock sensor was replaced in 2024 and I was denied engine replacement. This is a repeat failure of the same condition under Hyundai Motors TSB T3G Theta II. Once again, my safety was at extreme risk as the engine lost its power suddenly. It could have easily lead to a crash. In 2024, Hyundai and the dealer declined an engine replacement despite me showing the safety concerns and my possible eligibility for an engine replacement for the underlying condition.

ENGINE AND ENGINE COOLING

The contact owns a 2013 Hyundai Santa Fe Sport. The contact stated that occasionally, while driving at various speeds, an abnormal knocking sound was heard coming from under the hood while the accelerator pedal was depressed, and the steering wheel would shudder. The Check engine oil warning light illuminated. Upon further investigation, the contact related the failure to NHSTA Campaign: 17V226000 (Engine and Engine Cooling). The vehicle was taken to a local dealer, where it remains for further investigation; however, the vehicle was not diagnosed or repaired due to a lack of maintenance records, and the recall repairs were rejected. The manufacturer was made aware of the failure and determined that the recall repairs were performed under previous ownership; however, the recall repairs were not completed. The failure mileage was approximately 147,000.

ENGINE

I am reporting a serious safety defect involving my 2013 Hyundai Santa Fe Sport equipped with a Theta II engine While driving and exiting the freeway with my wife as a passenger, the engine suddenly failed after knocking symptoms and completely seized/locked while the vehicle was still in motion. The vehicle immediately lost motive power and came to a stop, creating an immediate and dangerous traffic safety hazard. Had this engine seizure occurred moments earlier while traveling at freeway speed, it could have caused a catastrophic accident involving serious injury or death. The Hyundai dealership diagnosed the vehicle with rod bearing failure, which is the known defect associated with Hyundai Theta II engine failures. My VIN falls under the Theta II extended engine warranty program, and the dealership confirmed eligibility and accepted the vehicle for inspection under that coverage. Despite this, Hyundai denied the repair claim, first alleging maintenance-related issues and later stating the vehicle was out of warranty. I maintain that the vehicle was properly maintained with oil changes performed approximately every 6,000/8,000 miles. Some calendar-time gaps occurred because the vehicle was stored and driven very little during my recovery from a personal injury surgery and recovery, but the vehicle was maintained on mileage intervals. This engine defect resulted in sudden engine seizure and total loss of motive power while driving, creating a serious safety risk to vehicle occupants and surrounding motorists. I am reporting this defect so it can be documented and investigated.

ENGINE

On [XXX] while entering the parking lot of my office, I noticed a blinking check engine light on the car's dashboard. I've never experienced this before so I called my husband. He asked me to use a diagnositic tool he kept in the car. I did and there was a code "P1326" when I pressed the key for more information it said something about the manufacturer. My husband told me to call the nearest dealer. I called Castle Hyundai in Downers Grove. I was instructed not to drive the care and have it towed to the dealership as soon as possible which I did. Castle Hyundai verified the P1326 code and fixed the knock sensor, changed the oil. I picked the car up on March 13. On [XXX], the flashing check engine light returned while driving home from work. Again, we used the diagnostic tool and again the code P1326 appeared. The car was towed back to Castle Hyundai. On Monday, I spoke with Christain Jones the service director because I hadn't heard anything about the car. He called later in the day and said that the car needed a new engine. He asked for records of my oil changes since purchasing the car in 2021. I emailed him three from 2022, 2023 and 2024, the four change was done by Castle on March 12 2026. I was told that he would send the the information to Hyundai regarding a new engine. However, he stated that he was not confident the company would approve the claim. This after, I received an email from Eric Marcum with Castle. The email stated that Hyundai denied the engine replacement due to "lack of maintenance". He wanted to know if we wanted an estimate on replacement of the engine. I responsed that I needed Hyundai's rejection in writing and I also wanted an estimate of the replacement. I attempted to contact Hyundai's Customer Care, however, their offices were closed until Monday. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After having the ABS recall fixed a while back all of the lights came back on about a week ago. There has been a loss of oil meaning i have been adding oil in between oil changes at least once a week, there has been smoke coming from under the hood and if you run the heat or air you have to have circulate cabin air button pushed or it pulls the smell inside the car and it is overwhelming. The smoking has been going on for about at least a month now.

ENGINE

While traveling at approximately 80 mph on the highway, my vehicle suddenly lost all response to the accelerator pedal. Despite continued pressure on the gas, the vehicle rapidly decelerated to approximately 40 mph on its own. There were no warning lights, unusual noises, or physical indicators of a problem before, during, or after the event. I was able to safely navigate the vehicle off the highway. The vehicle appeared to operate normally afterward. The following day, I brought the vehicle to a mechanic who was unable to replicate the issue and found no stored fault codes. No repairs were made. Given the known concerns surrounding the Theta II engine in this model year, I am submitting this incident for documentation purposes and to contribute to any ongoing or future investigation into sudden acceleration loss in 2013 Hyundai Santa Fe vehicles.

ENGINE

I requested Engine oil consumption tests on November 12, 2020 and March 27,2021 at Vandergriff Huyndai, Arlington, Tx. Nothing was resolved,. I have been adding oil myself and getting oil changes regularly since. At 146,000 miles it's been worse. After just 2,000 miles after an oil change it was below low, my mechanic topped it off 3 weeks ago and I've had to add oil since. Took my car to Jerry's Huyndai, Weatherford, Texas on December 29,2025. Due to oil consumption, smoke, smell, and I'm wondering if the vibrating is from the engine or if I need new spark plugs. I was told that my valve cover gasket needs to be replaced. I feel like I'm still getting the run around and the car can't keep oil above low level. I've never seen oil under the car and when i took the car to Vandergriff in 2020 and 2021 they didn't see a leak they said. I also took my car in 8/21 and had the ABS repaired and as of recent its out again. I took my car into an independent mechanic shop today 1/2/2026 and he said he felt that the valve cover gasket is not the main problem he feels it would be a waste of money until the engine is replaced. I also heard a new noise today not knocking but tapping noise while driving. My car has hesitated recently, but Jerrys huyndai didnt have that happen while driving it. My car would be available for inspection any time requested. I am just concerned about the smoking if it will get worse, is there a risk of fire and I'm disabled, so I'm concerned if I will have a problem getting out of the car in time if that were to happen or if the car would stop in the middle of the street. This is my only car and I care for 2 sons that are disabled. I need a safe car. Also, the car manager Rachel at Jerry's Huyndai seemed focused that I would be charged 225.00 if it was not the rod bearings. It just seemed like she more focused on that instead of finding the problem. The only lights on is the ABS.

ENGINE

The engine in my 2013 Hyundai Santa Fe 2.0T shut off suddenly while driving and would not restart. The dealership confirmed the engine is seized, has bottom-end knocking, and FAILED the BCT (bearing clearance test). Hyundai denied assistance claiming ‘maintenance neglect,’ but the mechanical failure is consistent with known Hyundai GDI engine defects. This presents a serious safety hazard because the vehicle lost power unexpectedly while in motion and could have caused a crash.

2013 HYUNDAI SANTA FE SPORT TURBO. PAST/PRESENT SAFETY-SENSITIVE DEFECTS, NOTED OVER THE PAST SEVERAL YEARS: 1. One Confirmed Open Recall [CAMPAIGN #/NHTSA RECALL #—Recall 251 / 23V651000] (To Be Scheduled ASAP). 2. RPM/Propulsion Limp-mode Conditions: Vehicle periodically loses RPM READINGS on Dash and goes into the Propulsion sputtering/restricted-speed limp-mode hesitation condition. This condition may occasionally normalize by stopping, turning off engine and restarting. This intermittent RPM/Propulsion condition sometimes occurs, signified by a temporary sputtering/bucking while driving vehicle. ❓️CHECK STORED CODES ASAP...To Do. 3. Several times the car failed to accelerate predictably. For example, as when trying to accelerate up to highway speed from the on-ramp, leading to a fear of a near-miss, stalling and getting rear-ended. On such occasions, since attention is directed outside of the vehicle for safety, the state of the RPM READING on the dash has not been noted. ❓️CHECK STORED CODES ASAP...To Do.

ENGINE

2013 Hyundai Santa Fe Sport 2.4L GDI engine failure due to known Theta II defect. Engine developed severe knocking and is unsafe to operate. The vehicle has experienced engine failure consistent with Hyundai’s recalled Theta II GDI defect (metal debris and bearing wear). Hyundai has refused to replace the engine, citing incomplete oil change records from a prior owner. This denial is unreasonable, as the defect is a manufacturer issue, not ordinary wear or maintenance neglect. The vehicle is unsafe to drive and at risk of stalling/fire. I request NHTSA investigate Hyundai’s refusal to honor its recall and extended warranty obligations.

NHTSA complaint #11680444 — an unverified report by a vehicle owner.

ENGINE

On Aug 2, 2025, while traveling back from vacation with our family of 4, our engine failed and completely seized up on a very busy highway. The vehicle completely shut off in a lane of travel near an exit ramp, and we were unable to even pull off on a shoulder for safety. We were unable to restart the vehicle or reproduce the issue because the vehicle will not turn on. There were no warning lamps or other messages. However, the car has historically consumed an extraordinary amount of oil, even with routine oil changes and service. Two quarts of oil were added to the vehicle the day before this happened. The vehicle was towed to a Hyundai dealership and the incident was reported to Hyundai USA. We've been told the dealership can not run tests or inspect the vehicle until Aug. 21, nearly three weeks after it happened. We were told this is because they have numerous other vehicles with similar problems. This was an incredibly terrifying experience that put the safety of our family of 4, including two young children, at risk. A bystander called 911 and a state trooper arrived to set up flares and expedite a tow truck. We were told the spot we broke down is an incredibly busy part of an interstate where fatal accidents happen every other day.

NHTSA complaint #11679241 — an unverified report by a vehicle owner.

ENGINE

While driving, my 2013 Hyundai Santa Fe suddenly began losing acceleration without warning. No check engine lights were on at the time. The RPMs surged to 5,000–6,000, but the vehicle failed to gain speed. Moments later, the car lost all power completely. The red engine warning light and battery light illuminated on the dashboard, and the vehicle became unresponsive and would not restart. I had the vehicle towed to a certified Hyundai dealership, where a diagnostic inspection confirmed a rod bearing failure — a well-documented issue associated with the Theta II engine. The dealership initially stated this type of failure should fall under Hyundai’s extended warranty related to the class action lawsuit regarding defective Theta II engines. I purchased the vehicle used in 2020 and have kept detailed maintenance records for every year of ownership, all of which I submitted to Hyundai in support of my engine replacement claim. Despite this, Hyundai denied coverage and declined to replace the engine. This type of sudden engine failure, without any prior warning indicators, is extremely dangerous and appears consistent with the known defects in Theta II engines previously investigated by NHTSA. I’m filing this complaint in the interest of safety, transparency, and accountability, especially as other drivers may be exposed to similar risks. I respectfully urge NHTSA to review this incident as part of its ongoing oversight of Hyundai’s Theta II engine defects and consider re-opening or expanding its investigation into these failures. I also request that NHTSA encourage Hyundai to reconsider its decision to deny my engine replacement claim, especially given the safety-critical nature of the failure and my full compliance with maintenance expectations.
