Owners have filed 472 complaints
about the 2017 Hyundai Santa FE Sport with NHTSA between 2017 and 2026.
The largest single group is the engine & cooling.
Across this model's run it ranks 1 of 6 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 — 91
Against the median year of the Hyundai Santa FE Sport. 50 means typical for this
model; 100 means roughly double.
Severity — 27
5.3% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 95
56% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
How 2017 compares with every other Hyundai Santa FE Sport
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.

When owners complained
A spike years after the car went on sale usually means a part wearing

NHTSA investigations into the 2017 Hyundai Santa FE Sport
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.
The Office of Defects Investigation (ODI) has received eight Hyundai Motor America (Hyundai) and eight Kia America, Inc. (Kia) Part 573 Recall Reports between 2016 and 2023. The combined 16 safety recalls all involve the antilock braking system (ABS) modules or Hydraulic Electronic Control Units (HECU) manufactured by the equipment supplier Mando. The Part 573 Recall Reports contain varying defect descriptions and differing remedy descriptions for the same or similar equipment supplied by Mando. Safety recalls included in this Audit Query (AQ) review include: Hyundai recalls 20V-520, 20V-543,...

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 2017 Hyundai Santa FE Sport
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.

Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.

ENGINE
The engine on my 2017 Hyundai Santa Fe sport was deemed defective according to Downey Hyundai. They ran a diagnostic test on it and it failed the test. They offered to replace it for me at no cost to me. On December 11, 2025 the engine caught fire while the service technician from Downey Hyundai was “test driving” it in a drive-thru of 7 Leaves. He was using my vehicle for personal use when the engine fire occurred. Both Downey Police Dept and Downey Fire Dept made reports. I did file a claim with my insurance company, AAA. On 12/8/25, the engine oil light blinked once very quickly on the dash and that was it. I took my vehicle to Downey Hyundai the very next day to have it inspected.

STEERING
I am the current owner a 2017 Hyundai Santa Fe Sport. While I was driving my SUV on the highway at highway speeds at 60mph, the oil pressure and the check engine warning light illuminated all of sudden after around 1 hour of smooth ride. In the meantime, suddenly the vehicle lost motive power, the steering wheel seized and smoke came immediately. Losing motive power in running conditions and smoke coming out during failure could have endangered our lives. The smoke came out due to leakage of engine oil probably. The vehicle was stuck in the middle of the road. The vehicle was towed to the residence and then after Hyundai Dealership. The dealer was made aware of the failure. The failure mileage was approximately 76,245 only. Before reporting to NHSTA I have seen numerous complaints about high oil consumption and burnt valves on Theta II engines around 2017 santafe sport model and very similar occurrence of events happening to all while driving the vehicle on highways. Hyundai must need to provide support to this year model and make vehicles.

My 2017 Hyundai Santa Fe had a new engine installed at the dealership, Fred Beans Hyundai Flemington, NJ. I picked it up on [XXX] on [XXX] (and after 134 miles) my car's check engine light came on. I rerouted to dealership about 8 miles. Sitting outside service bay, I smelled smoke and then saw smoke coming out of vents. I then jumped out of car and the car became engulfed in flames and subsequently exploded. The day I picked it up, I pointed out to the service manager that they had not reattached everything to the car properly, sloppy workmanship. Best guess is that they did not attach a valve correctly.

VEHICLE SPEED CONTROL
On February 24, 2026, I had the 9C2 software update. My vehicle was being checked for oil consumption. Since then I have had issues with it hard shifting when first starting to drive and sometimes after I've been driving a while. This has continued miles down the road, sometimes over thirty minutes after driving. It also just feels continuously like it is not driving smooth. This only started after the update. I contacted HMA. The first person on my case (Gurvinder) told me I needed to return my car, not to drive it. I had bronchitis, so I did not immediately do that. The next person "Rainey" told me it is a KNOWN issue and they are telling people to warm their cars up for around 3 minutes, and it will be fine. I'd done that, and even driven longer than that. I told him that. I took my mother-in-law home from church miles from there after collecting her at the church door, etc... Getting to the hill at to her home, I didn't think it was going to get up it. Often I don't think I'm going to get out of my driveway, a dangerous driveway in a curve. He wanted Krause Hyundai to contact HMA Engineer. When I was at Krause, they didn't know how to get ahold of HMA Engineer. Dalton also said they can't back the update out. I'm on my third HMA Case Manager. She keeps changing what I've told her is wrong in the emails, I don't think she knows anything about cars. She won't listen when I say I spoke to Dalton at Krause; she keeps speaking to John. [XXX] said they can do diagnostic, but it will cost me. I refuse to pay as [XXX] and Gurvinder had months before wanted me to take it back to get fixed, and Rainey wanted Krause to contact the engineer. It is a known issue with a letter written by Hyundai. Getting a diagnostic code reading performed is not going to help. I'm afraid my vehicle will lose power on the road and I will be struck.

Fredericksburg, TX
ENGINE
We have a 2017 Hyundai Santa Fe Sport with a refurbished engine due to a past class act settlement, we were notified by Hyundai to bring in the vehicle for Service campaign 9C2 to update the Engine Control Module (ECM) Software for vehicles equipped with the (2.4 GDI) Theta II refurbished engine, which we have. The morning after we updated the 9C2 software, after starting our car cold for the first time in the am, our car went into limp mode, shaking very badly, it would not accelerate above 20 MPH, it had a lot of trouble shifting from 1st to 3rd gear and acted like it was going to stall out and then die in the middle of the road while I was in the car with my 2 children. The dealership we took it to was not able to duplicate the limp mode, but has documented that they did witness hesitation and sluggishness while test driving it. I cannot validate that it was test driven cold immediately as requested as all their test drives were done without me. Due to the vehicle not accelerating as it should normally, I feel the vehicle is very unsafe and unreliable as well. I’m willing to provide more documentation, and our car is available for further inspection. I did request the help of a Hyundai customer relations case manager who stated Hyundai is aware of all of the drive-ability issues I have stated and he said they are hoping to provide another software update, but that time frame is unknown. Dealership mechanic stated the same thing and believes our issue is related to the 9C2 update. The manufacture has not inspected the vehicle, but we would absolutely love them to if they would. There have been no check engine lights come on before or after this update, only misfire codes came up after the update which dealership has those, and since the dealership was unable to witness it going into limp mode while driving it, they could not gain the much needed data that pinpoints the exact problem. We were advised to warm up car and rev up the RPM to above 2,000 before driving.

The vehicle exhibits rough or delayed gear shifting, a noticeable lack of power/acceleration, and behavior that feels like the engine is not receiving adequate fuel. This occurs both during cold start and after the vehicle has been driven and is fully warm. I returned the vehicle to the dealership (Wallace Hyundai), where the service advisor personally test drove the car with me and confirmed he could feel the hesitation firsthand. Despite this, the dealership stated no issue was found and advised warming the car up for 1-3 minutes before driving as a workaround. I tested this exact recommendation, and the issue returned even after the vehicle was fully warmed and had already been driven. Hyundai Motor America's National Consumer Affairs department has stated this is "under review" but has also described the hesitation as "normal" cold-start behavior related to catalyst warm-up. This does not match what I am experiencing, since the issue also occurs when the vehicle is already warm, and their own dealership's advisor confirmed the problem exists. I have also noticed a decrease in fuel efficiency (MPG) since the software update associated with this recall. This issue directly affects the safe operation of the vehicle — specifically the ability to accelerate reliably, including in situations like merging onto highways or pulling into traffic, where a lack of power could result in a collision. I do not consider the vehicle safe to drive in its current condition.

Campaign 9C2 was installed on this vehicle and the now the vehicle is a danger to drive. My wife refuses to drive it as it bucks and jerks as well as the gas mileage has decreased from 35 highway to 28 highway. The fuel trims are way off on cold starts and the transmission now searches for the correct gear. Shifting back and forth. Just a slight touch of the accelerator and the car seems to jump forward which makes stop and go driving almost impossible.

STEERING
Steering column sensor issue reported by Hyundai dealership. This has happened a several times before causing the steering wheel to “lock up” when driving making it very hard to turn my wheel. I have had to pull over, stop, and turn off the car and then back on again, which resets it, and I’m able to drive as normal, until it happens again. This most recent time, 6/2026, I was able to take it in to a dealership when the warning lights were on. He did a recalibration, however, later when driving, the same issue arose at high speeds, on the fwy, causing me to exit and pull over. * I noted 2- 3 warning lights came on during the malfunction.

What component or system failed or malfunctioned, and is it available for inspection upon request? Multiple systems have failed sequentially — engine (replaced at ~84,000 miles), catalytic converter (replaced post engine replacement), and transmission (currently stalling, pending replacement authorization from Hyundai Corporate). The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? The vehicle stalls during the first few miles of every drive before stabilizing. This creates an immediate risk of accident on public roads, particularly at intersections, highway on-ramps, and in traffic. Despite this known safety hazard, the dealership returned the vehicle to me unrepaired on June 22, 2026, and deemed it safe to drive. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Fort Mill Hyundai (805 Gold Hill Road, Fort Mill, SC 29708) has confirmed they can physically feel the stalling issue but stated they do not have sufficient data to submit to Hyundai Corporate for transmission replacement authorization. An independent mechanic also previously confirmed the engine issue that the dealership initially dismissed. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. Fort Mill Hyundai, an authorized Hyundai dealership, has inspected the vehicle multiple times over several years. The dealership is actively coordinating with Hyundai Motor America Corporate regarding the transmission replacement. Invoice reference: [XXX], dated June 22, 2026. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. Check engine and brake warning lights first appeared at approximately 64,000 miles. These lights recurred repeatedly every ~1,000 miles despite multiple dealership visits. Subsequent symptoms included engine hesitation and loss of power, fol INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INF

My 2017 Hyundai Santa Fe sport has never had any issues until last Friday when I took my car to the dealership for regular maintenance (oil change, tire rotation) as I always do. They also performed a software update for recall campaign 9C2. Every day since, when first starting the car after it’s been resting for a while, I’ve experienced a jerky transmission and rough shifting for a first couple minutes of driving. Hyundai has acknowledged they are aware of this issue related to the campaign and the dealership said they’ve had many customers complaining of the same problem following the recall update. However, Hyundai has offered no resolution, other than recommending the car warm up for 13 minutes after starting. Hyundai needs to correct the issue they caused, as my car was perfectly fine before it was serviced and now it’s not performing properly.

Following the completion of an official emissions recall software upgrade at Fitzgerald Auto Mall Countryside, Clearwater Florida, my 2017 Hyundai Santa Fe Sport (52,000 miles) now suffers from a severe loss of motive power and erratic transmission shifting/jerking during cold starts throughout day. The vehicle continues to hesitate during cold starts, making it impossible to safely accelerate from a stop into incoming traffic. I returned to dealership on 5/29/26 to address continued driving issues. The servicing dealership states they don't have a software fix and offer no mechanical fix. The dealership states they received an internal memo from Hyundai Corporate which instructed the dealership to tell affected owners to idle the vehicle for 1-3 minutes before driving to allow system adjustments. Forcing a consumer to wait out a dangerous powertrain defect in a running vehicle to avoid a roadway acceleration/loss accident is an unacceptable safety hazard. The manufacturers recall update has actively compromised the safe operation and motive control of this vehicle.

After the ECM recall for a software update the car would not run correctly. It jerks and and runs rough. It almost stalls when you put your foot on the gas. I took it back to the dealer and they can not get the problem to duplicate. Noone else has looked at the problem. There were never any problems with the care until the recall. The problem occurred the day I brought the car home from the ECM update.
