Owners have filed 283 complaints
about the 2019 Hyundai Santa FE with NHTSA between 2018 and 2026.
The largest single group is the engine & cooling.
Across this model's run it ranks 10 of 26 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 35
Against the median year of the Hyundai Santa FE. 50 means typical for this
model; 100 means roughly double.
Severity — 84
16.3% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 100
78% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
How 2019 compares with every other Hyundai Santa FE
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

NHTSA investigations into the 2019 Hyundai Santa FE
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Loss of Motive Power
The National Highway Traffic Safety Administration (NHTSA) 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.

Recalls on the 2019 Hyundai Santa FE
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
United States — NHTSA
23V181000
TRAILER HITCHES
Hyundai Motor America (Hyundai) is recalling certain 2019-2023 Santa Fe, 2021-2023 Santa Fe HEV, 2022-2023 Santa Fe Plug-in HEV and Santa Cruz vehicles potentially equipped with a tow hitch harness installed as original equipment, or purchased as an accessory through a Hyundai dealership. Water accumulation on the tow hitch harness module printed circuit board (PCB) may cause an electrical short, which can result in a fire.
Risk: A fire while parked or driving can increase the risk of injury.
18V715000
AIR BAGS:SIDE/WINDOW
Hyundai Motor America (Hyundai) is recalling certain 2019 Hyundai Santa Fe vehicles. The Side Curtain Air Bag (SCAB) mounting bolts may interfere with and damage the air bags during deployment.
Risk: In the event of a crash, if the air bags become damaged during deployment they may not inflate properly, increasing the risk of injury.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 2024552824,695 units in Canada
Label
Issue: On certain vehicles, the compliance label may be missing information in French. The words listed on the label for "Tires", "Rims", "Front" and "Rear" appear in English only, when they should be listed as "Tires/Pneus", "Rims/Jantes", "Front/Avant" and "Rear/Arriere". Canadian regulations require this information to be listed on the label in both English and French. Safety Risk: These small errors do not affect vehicle safety. Corrective Actions: This is not a recall. The company has corrected the compliance label for all new vehicles.
Recall 20231471,897 units in Canada
Electrical
Issue: Certain vehicles may be equipped with a 4-pin accessory trailer wiring harness kit that could fail. Over time, this could result in a short circuit that can cause the control module to overheat. Note: This recall only affects Hyundai Genuine 4-pin tow hitch wiring harness kits with the part number S2F67-AC401. These kits may have been ordered at the time of a vehicle purchase or purchased separately from a dealer as an aftermarket accessory. Safety Risk: A short circuit can create a fire risk, even while the vehicle is parked and turned off. Corrective Actions: Hyundai will notify owners by mail and instruct you to bring your vehicle to a dealership to inspect the vehicle for a trailer wiring harness kit. If necessary, the dealer will install a 15A fuse and a wire extension kit. Hyundai advises that if your vehicle has a tow hitch harness installed, you should park it outdoors, and away from other vehicles or structures until the recall repairs have been completed.
Recall 2019640275,533 units in Canada
Engine
Issue: Hyundai Auto Canada is conducting a Product Improvement Campaign that provides an update to the engine control module to detect potential problems before an engine fails. An engine failure would cause a sudden loss of power with an inability to restart. Note: This affects Sonata and Santa Fe Sport equipped with a 2.4 L GDI or 2.0 L Turbo GDI engine, as well as Tucson equipped with a 2.4 L GDI engine. Safety Risk: A sudden loss of engine power could increase the risk of an accident. Corrective Actions: The company will notify owners by mail.

SERVICE BRAKES
The contact owned a 2019 Hyundai Santa Fe. The contact stated that as his daughter was driving at 20 MPH on the highway, she depressed the brake pedal, the brakes failed to respond, and the vehicle started to smoke from the engine and into the cabin. There were no warning lights illuminated. The contact's daughter then tried to depress the brake pedal again, and the contact's daughter then jumped out of the vehicle on the ramp. The vehicle was coming down on the intersection unoccupied, engulfed in smoke, initially hitting a stop sign and then another unknown sign and sequentially coming to a stop. The contact then saw the vehicle at the hillside engulfed with fire and smoke and tried to break a window, however, the contact heard his daughter and stopped. The Fire Department and Police Department were on scene and extinguished the remaining of the fire and the hillside. The origin of the fire was on the engine. The manufacturer was not made aware of the failure. The vehicle was consumed by the fire and the remainder were taken to Lenzi Automotive. The contact was the only occupant in the vehicle and sustained scrapes and bruises to her elbow, finger, right thigh, buttocks, and back rib that require medical attention. The failure mileage was approximately 77,200.

The vehicle suffers from recurring, sudden loss of motive power and transitions into engine "limp mode" while driving in active, heavy traffic. This severe drivability defect has occurred on four separate occasions under Diagnostic Trouble Code (DTC) P00AF00 (Turbocharger/Supercharger Boost Control "A" Module Performance) and related boost/MAP faults (P0234). During these episodes, the vehicle abruptly loses acceleration capability without warning, creating an acute collision risk when navigating highway traffic and intersections. The turbocharger assembly has required replacement three separate times due to recurring oil contamination from the engine crankcase. Despite meticulous maintenance (documented synthetic oil changes every 3,000–5,000 miles since new), the manufacturer and dealership have repeatedly blamed peripheral turbo components rather than diagnosing or repairing the root cause (I suspect excessive engine crankcase pressure/piston ring blow-by based on the significant oil deposition on the turbo, map sensor, and pooling in the intake line).

Transmission was replaced under warranty by Hyundai in Nov 2024. Engine was replaced at 100600 miles in Nov 2025. Issues with the transmission were happening at that time but ignored by dealership as issues related to failing engine. Our mechanic confirmed in April that transmission was failing and told us to go to Hyundai. We went to dealer in April 2026. They confirmed transmission needed to be replaced. They were going to contact Hyundai USA. We received no updates despite many calls to the dealer. We had to call Hyundai USA directly. They opened a case. Dealer finally called and took car in and requested good faith repair by Hyundai USA. Hyundai USA responded 2 weeks later and is not covering anything. They replaced our transmission in Nov 2024 with a refurbished transmission that they NO LONGER MAKE. Clearly due to the fact that the refurbished part doesn’t work. They now want me to pay $8000 to repair transmission. My car has been maintained on schedule by my mechanic. All paperwork available. I have had Toyotas, Hondas and chevys that have lasted close to 20 years. This has been a horribly disappointing experience. And I now need to buy a new car for my 17 year old instead of handing down. I will NEVER buy another Hyundai. I want everyone to be aware of my experience. Disgusting customer service by Hyundai USA.

COMPLAINT SUMMARY: [XXX] / ENGINE THERMAL FIRE RISK / WARRANTY DECEPTION My 2019 Hyundai Santa Fe (2.4L GDI Engine) is experiencing severe powertrain degradation under the known Theta II engine defect class-action framework. On November 7, 2025, the vehicle logged a Permanent Diagnostic Trouble Code (DTC) P1326 via an independent scan, indicating catastrophic internal rod bearing wear. On XXX, the vehicle was brought to Hyundai of Milledgeville for safety recall verification. Instead of executing the mandatory corporate-directed Bearing Clearance Test (BCT) to replace the failing engine block, the service department committed technical campaign malpractice. The technician forced the 9C2 ECU Software Update directly over the locked mechanical fault to suppress the dashboard warning lights and alter the vehicle's ROM ID parameter limits. When caught via a photograph of their active GDS diagnostic tablet showing 7 historical system faults, the service manager provided a truncated printed report hiding Page 1 and omitting the critical P1326 powertrain code count to evade a warranty engine replacement. Due to these unmitigated delays, the vehicle has suffered severe consequential safety damage. The advanced engine degradation and oil consumption have flooded the exhaust system, melting the catalytic converter substrate and triggering a new DTC P042000 (Catalyst Efficiency) fault immediately after the dealer visit. The extreme engine vibrations have also damaged the transmission's torque converter clutch (DTC P074100). The dealership refused a service loaner and knowingly sent a disabled consumer and an elderly passenger away in an active, failing vehicle that presents a sudden stall-on-highway hazard and a severe thermal exhaust fire risk under extreme summer heat conditions.

My 2019 Hyundai Santa Fe 2.4L (VIN: [XXX]) is experiencing a severe safety defect involving rapid engine oil starvation. The vehicle recently failed an official oil consumption test conducted by Fred Beans Hyundai of Abington, where it was documented that the engine consumed 1 quart of oil in just 881 miles (PA Request #XXX). This vehicle is equipped with the Theta II engine, which currently has active warranty extensions (TXXC and TXXI) specifically covering connecting rod bearing failure. Despite the documented severe oil loss—which is the primary known cause of connecting rod bearing wear and sudden engine seizure—Hyundai Corporate (Case #XXX) is refusing to evaluate the vehicle under these warranties. They have improperly classified my claim as a denied "goodwill" request and are refusing to perform a connecting rod bearing clearance test to determine if the bearings have been damaged by this starvation. Because Hyundai refuses to perform the required diagnostic safety protocols, the vehicle must be driven in an oil-starved condition. This poses an imminent and severe safety risk of sudden engine seizure, stalling, and complete loss of motive power at highway speeds without warning, which could result in a catastrophic crash. The manufacturer is ignoring their own failure thresholds and putting driver safety at risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On March 04, 2026, I took my 2019 Hyundai Santa Fe to the local dealer for oil change service. As part of that service visit, they performed Hyundai recall 9C1 which was supposed to lower tailpipe emissions. The next morning, and ever since, my vehicle ran differently. The engine had several 1000rpm surges and was sluggish at other times. This behavior has continued. Particularly when I first start out in the morning and the engine is cold. Never after the engine is warmed up. A visit to the Hyundai forum shows a growing list of other Hyundai owners who are experiencing the same issues. This recall is defective and should be corrected.

The vehicle recently failed an official oil consumption test conducted by Fred Beans Hyundai of Abington, where it was documented that the engine consumed 1 quart of oil in just 881 miles (PA Request #XXX). This vehicle is equipped with the Theta II engine, which currently has active warranty extensions (TXXC and TXXI) specifically covering connecting rod bearing failure. Despite the documented severe oil loss—which is the primary known cause of connecting rod bearing wear and sudden engine seizure—Hyundai Corporate (Case #XXX) is refusing to evaluate the vehicle under these warranties. They have improperly classified my claim as a denied "goodwill" request and are refusing to perform a connecting rod bearing clearance test to determine if the bearings have been damaged by this starvation. Because Hyundai refuses to perform the required diagnostic safety protocols, the vehicle must be driven in an oil-starved condition. This poses an imminent and severe safety risk of sudden engine seizure, stalling, and complete loss of motive power at highway speeds without warning, which could result in a catastrophic crash. The manufacturer is ignoring their own failure thresholds and putting driver safety at risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On March 04, 2026, I took my 2019 Hyundai Santa Fe to the local dealer for oil change service. As part of that service visit, they performed Hyundai recall 9C1 which was supposed to lower tailpipe emissions. The next morning, and ever since, my vehicle ran differently. The engine had several 1000rpm surges and was sluggish at other times. This behavior has continued. Particularly when I first start out in the morning and the engine is cold. Never after the engine is warmed up. A visit to the Hyundai forum shows a growing list of other Hyundai owners who are experiencing the same issues. This recall is defective and should be corrected.

In December 2025, a Hyundai dealer performed Service Campaign 9C2 (TSB 25-01-087H), an ECU software update for the 2.4L GDI Theta II engine, during a routine annual NY state emissions inspection. Immediately following this update, the vehicle began exhibiting an RPM flare of approximately 1,200-1,500 RPM during upshifting under light acceleration. This behavior did not exist prior to the update. The condition occurs when ambient temperature is above 50°F and the vehicle has been parked 2+ hours after a prior drive. No warning lamps or fault codes have been present at any point. The issue has been confirmed across four dealer visits at two Hyundai dealerships over five months. Attempted remedies included transmission ECU updates and adaptive resets — none resolved the condition. On the fourth visit, the technician personally experienced the issue and identified reinstalling the pre-update ECU calibration as the likely fix, but stated the prior software version was unavailable. The repair order was nonetheless closed as "vehicle operating as designed." The case has been escalated to Hyundai Motor America National Consumer Affairs and forwarded to Hyundai engineering with no resolution to date. Multiple other 2019-2020 Santa Fe owners report identical post-9C2 symptoms on public forums, indicating a pattern associated with this campaign's ECU calibration. The unexpected RPM surge and erratic shifting during acceleration creates an unpredictable driving experience that could cause hesitation in traffic situations requiring smooth acceleration.

Vehicle: 2019 Hyundai Santa Fe, VIN [XXX] , exterior Quartz White Pearl. Component: Exterior factory paint (paint/trim). Complaint: This vehicle exhibits a systemic, progressive factory paint defect — excessive peeling and bubbling of the white finish that spreads from one body panel to the next. This is a known defect across this vehicle generation; Hyundai acknowledged it by issuing Warranty Extension Z05 (TSB 25-BD-004H), which extends paint coverage to 10 years/unlimited miles for affected white-paint vehicles including the 2019 Santa Fe. Hyundai repaired the hood under this warranty in 2025, during which the vehicle was out of service for 77 consecutive days. Since that repair, the defect has migrated to the adjacent fender and has also appeared on a door, demonstrating that it is spreading across the vehicle. Hyundai has offered to repaint only the single currently-visible panel rather than addressing the systemic defect. I am filing this complaint to document the defect and its progression, and to support the public record regarding factory paint failure on these vehicles. No crash, injury, or fire has resulted. The vehicle is owned by my spouse; I am submitting as authorized representative. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Hyundai recently had a service campaign that was issued to address an emissions related issue in CA. The service campaign was 9C2 and the TSB was 25-01-087H. After this software update was applied to my vehicle the engine is now sluggish on a cold start and the transmission is shifting differently at low speeds and low gears. It appears that the performance of my vehicle has been compromised. There is a Hyundai forum where many Santa Fe owners are experiencing the same issues after the software update. I have notified the service advisor at my local Hyundai dealership.
