2014 Hyundai Santa Fe Sport: engine knocking or ticking

Filed Jul 8, 2026 · Acceleration, Brakes · OK

I am reporting a severe safety failure on my 2014 Hyundai Santa Fe Sport that perfectly matches the safety defect described in Recall 21V‑303 / Campaign 205. This happened even though I had the dealer perform the official recall fuse fix back in 2024. The problem started after I left the car parked for about 3 to 4 hours. When I came back, I heard a motor (not the motor) loudly running under the hood even though the ignition was completely off. It stayed on even after starting and turning the car off. The battery in the vehicle had drained so bad it was deemed bad when hooked up to a tester at the auto parts store. After getting a new battery and trying to drive the car, the electrical system went haywire. The dashboard lit up with every brake warning light on, the speedometer stopped working, miles to empty being erratic, and the exterior rear brake lights kept flickering erratically after the car was turned off. The steering was acting abnormal and unnatural, not crisp and easy to turn as usual. There were absolutely no warning lights or symptoms before I parked the vehicle. I had it towed to my local Hyundai dealership, and their diagnostic scan confirmed major brake and chassis issues, specifically code C2402 for an ABS Pump Motor Circuit Malfunction and codes C1200, C1203, and C1206 for a loss of wheel speed data. The vehicle has not been inspected by police or insurance representatives, but it is currently sitting at the dealership waiting for a resolution from a Hyundai customer care case manager. The 2024 recall remedy only involved dropping the fuse amperage to mitigate fire intensity; it did not replace the module housing or prevent the internal brake fluid leak from eventually destroying the system. The defect has seemingly now fully manifested, knocking out primary braking indicators and power steering assist, presenting an ongoing safety and fire hazard while driving and parked.

On March 20, 2026, while driving, my 2014 Hyundai Santa Fe Sport (VIN: [XXX]) equipped with a Theta II 2.4L GDI engine, the car experienced a catastrophic, sudden loss of motive power. The engine suffered a total mechanical failure/seizure, creating an immediate highway safety hazard. This vehicle is part of the "In re: Hyundai and Kia Engine Litigation II" settlement population due to known factory manufacturing defects where residual metal debris blocks oil flow to the connecting rod bearings. Hyundai Corporate has issued a blanket refusal to honor the lifetime safety warranty extension, using an unverified allegation of "outside influence" to avoid executing the mandatory engine replacement protocols required under the federal safety agency Campaign T3G.

The engine failed completely and is currently available for inspection at my residence. While traveling on a family vacation at highway speeds, the engine suffered a catastrophic connecting-rod bearing failure and seized. This caused an immediate loss of motive power, braking assistance, and steering control, nearly resulting in a fatal multi-car collision with my child in the vehicle. Warning lights illuminated on the dashboard during the failure as a sudden metallic knocking sound occurred and the engine died. The vehicle became completely disabled and had to be limped off the highway and towed. The VIN has a completed Campaign 953 from September 2019 qualifying it for the Lifetime Warranty Extension under the Theta II settlement.

I dont know the exact component that's failed, but it is consuming way too much oil, i have to put a quart in just about everytime i drive it. When i took it the dealership to find out if it was leaking, or burning oil, they literally charged me 200 to tell me it was either leaking oil or burning it. I personally think it is burning vs leaking, because there isnt oil in my drive way. I then spoke to some one on their YouTube channel that told me to call and tell them my story and they should help me out. I did that but no one ever contacted me about the complaint. It's smokes from the engine and i feel like its just a matter of time before it blows up or catches fire. Even though I can hear the engine ticking and struggle the check engine light is not on. From what I've seen this is a known issue that they are ignoring, even though MANY people have complained. This engine has already been replaced in 2018, and the new one is going bad prematurely as well.

While driving on a steep, narrow grade with no safe shoulder, my 2014 Hyundai Santa Fe Sport suddenly lost all forward power. The engine would rev but the vehicle would not accelerate. I was left stranded in traffic, with cars behind me and nowhere safe to pull off, creating an immediate risk of being rear-ended or rolling back into other vehicles. I had to call for a tow to avoid a serious crash. The vehicle was marked as having all recall campaigns completed, including the rod bearing inspection and knock sensor update, which were supposed to protect against catastrophic engine failure. Clearly, those campaigns were not sufficient to prevent the failure I experienced. At the time of failure, the vehicle displayed the check engine light and drivability symptoms consistent with abnormal combustion and potential bearing damage. Hyundai denied lifetime warranty coverage under the Theta II engine settlement without performing the required inspection. Instead, I was left with an estimate for engine-related repairs that exceeded the value of the vehicle, effectively rendering it a total loss. This failure is exactly what Hyundai’s recall notices describe as a risk: sudden engine failure, loss of motive power, and increased risk of crash. The fact that this happened to my vehicle despite “completed” recall campaigns raises serious concerns about whether the defect remains unresolved and whether Hyundai is adequately honoring its recall and settlement obligations. I am requesting that the federal safety agency investigate whether Hyundai is improperly denying warranty coverage without inspection and whether vehicles that were marked as repaired under these recalls are still at risk of catastrophic engine failure, stalling, and loss of motive power on public roads. The settlement administrator also works for Hyundai is just referring customers back to Hyundai Customer Care. They are not honoring this CLASS ACTION lawsuit and acting in BAD faith and putting lives at risk.

My 2014 Hyundai Santa Fe Sport suffered a blown head gasket that required me to pay $9,000 for a full engine replacement. Hyundai is aware of ongoing problems with their 2.0 turbo motors, but the recall only covers the rod bearing failure/knock sensor issue. Many owners, including myself, are experiencing blown head gaskets, and several believe this failure is directly related to the same underlying engine defect. This is not an isolated case—numerous complaints online and in owner forums describe the same problem. Despite the high repair cost and known engine vulnerabilities, Hyundai refuses assistance because my vehicle is outside the mileage limit, even though the defect is widely reported and appears to be a design/manufacturing issue, not normal wear and tear. I believe the federal safety agency should investigate whether the head gasket failures in these 2.0 turbo engines are linked to the same defect that prompted Hyundai’s engine recalls, as it presents significant safety risks (engine overheating, sudden power loss, potential for fire). In 2018, the Center for Auto Safety formally petitioned the federal safety agency to investigate 2011–2014 Hyundai Santa Fe models (among others) due to a high number of non-collision fire complaints, including reports of melted wires, smoke, and burning odors in the engine bay . While this isn’t directly about head gasket failures, it underscores a pattern of serious safety-related issues affecting that generation of Santa Fe vehicles.

Vehicle is only 10 years old and barely has 120k miles on it. Consistent maintenance and oil changes are done. My son was driving on the highway and the vehicle died suddenly and coasted to the side of the road. We had it towed to a repair shop and after some testing they said the engine has seized up. Most likely related to the common rod bearing issue with these motors, but this is not on the recall for some reason. This should not happen on a car with so low miles and use! Luckily my son was safe and not in an accident when this happened.

January 2024, my 2014 Hyundai Santa Fe entered limp mode and displayed code P1326—known to indicate engine bearing failure under Hyundai Recall 162. I took it to Terry Reid Hyundai (Cartersville, GA), paid $175 for diagnostics, and was told the vehicle “passed.” However, I was never given a bearing clearance test (BCT) result, and no VIN-tied data was submitted to Hyundai’s internal WebDCS system, as required by TSB 23-EM-001H. Later communication with Hyundai confirmed that all BCT results—pass or fail—must be submitted and tied to the VIN in WebDCS, yet Terry Reid produced no record. Instead, they provided a blank Multi-Point Inspection (MPI) sheet and handwritten notes—none of which constitute a BCT or fulfill Hyundai protocol. In April 2025, the engine failed catastrophically. Shottenkirk Hyundai performed a proper BCT, revealing cylinder #2 at 1.13mm (well beyond failure limit), and submitted both the test and an oil sample to the lab. The oil analysis showed no sludge, fuel, or coolant contamination, contradicting Veritas Global Protection’s and Hyundai’s claim of owner neglect. Despite clear lab evidence, Veritas denied my claim, falsely asserting: The sludge existed before contract purchase (no proof), No rod bearing clearance documentation was submitted (Shottenkirk did), A prior P0420 code related to the catalytic converter caused sludge (mechanically inaccurate). Hyundai’s consumer affairs rep later claimed internal records can’t be shared, that even more evidence wouldn’t matter, and that Hyundai branded the engine based on “exceptional neglect” solely due to one missing oil change receipt—despite a clean oil report and lack of dealership testing. She also confirmed Hyundai does not notify consumers when engines are branded.This pattern shows coordinated misrepresentation between Hyundai, Veritas, and Terry Reid Hyundai. They failed to follow protocol, withheld required data, falsely blamed the consumer, and denied a legitimate claim despite lab evidence

Engine is burning oil at a rapid rate. Completed oil change on 12/6/2024 at 94380 miles. On [XXX] check engine light came on at 96684 miles. Dipstix Oil Change checked oil level and level was at least 2 quarts low. Dipstix Oil Change filled oil reservoir. On [XXX], check engine light came back on. SUV was taken to AutoZone and computer said light was due to bad oxygen sensor. Deal's Auto changed oxygen sensor for $557 on 2/24/2025 at 96708 miles. On [XXX], check engine light came back on and engine had a knocking noise. Vehicle was towed to Hyundai in Batesville, MS on 4/17/2025 for $498. Engine was checked by Hyundai on 5/23/2025. Oil level was at least 2 quarts low and dealership recommended an oil change (paid by me) to see if there is oil consumption. I live 8 hours from dealership and already know there is oil consumption. Dealership wants to simply get the vehicle off their hands and is placing consumer at risk with lazy diagnosis.

I am submitting this complaint regarding a serious engine defect in my 2014 Hyundai Santa Fe, which suffered rod bearing failure and now requires a full engine replacement at a cost of approximately $8,600. This failure occurred on April 13, 2025, despite regular oil changes and proper maintenance throughout my 1 year and 7 months of ownership. According to my certified mechanic, the vehicle was evaluated using Hyundai’s own rod bearing clearance test protocol, which it failed. The results were submitted to Hyundai by the repair shop, but the manufacturer denied the claim—despite their own diagnostic test confirming the issue. I later discovered that my vehicle may fall under the federal safety agency Campaign Number 17V226000 (Recall 162), which addresses machining errors in the Theta II GDI engine that can cause premature bearing wear. I am requesting that the federal safety agency investigate whether my vehicle should be formally included in this recall or covered under Hyundai’s extended warranty program for rod bearing failures. This issue represents a serious safety risk. The engine began knocking suddenly, without any warning lights or codes, and still had another month or 1,419 miles left till next service and oil level was normal. Vehicle had to be towed to a service facility. A failure while driving could have resulted in a complete engine seizure, placing my family and others at risk. I respectfully request that the federal safety agency review this issue and investigate Hyundai’s handling of such claims, especially where their own testing confirms a known defect.
