In June 2026 I took my vehicle to Hyundai for a recall to the ECM module. After that my vehicle would lose power and hesitate to shift gears, and overall does not feel safe. Took vehicle back to dealer and they have told me that I have to wait for them to issue a recall fix for this now .
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. I tried uploading both pdf and jpg, but it wouldn't let me. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
After the recent "important service campaign" involving the THETA II Emissions Logic Improvement my vehicle no longer safety shifts into the lower gears. It will not shift into gear. I am unable to safely get up to a normal speed and the engine and vehicle start shaking. This is isolated to the initial start of the vehicle and any low speed driving after. The issue is resolved after restarting the car, suggesting it is a software issue. This issue immediately began after the ECU update for the THETA II emissions logic improvement on 5/12/2026.
Airbag light illuminates on the dash and the seatbelt light illuminates intermittently as the seat electrical harness under the seat only connects in certain positions of the seat. My issue is associated with the passenger seat. This airbag light is associated with the airbag not firing or improperly firing. To avoid a recall, Hyundai has extended the warranty for vehicles for this issue but refuses to fix mine without payment.
Odometer Fraud. The contact purchased a 2017 Hyundai Santa Fe Sport. The vehicle was a dealer sale. The contact stated that while attempting to trade the vehicle, the contact was informed by the dealer that the odometer had been rolled back prior to the purchase. The contact had purchased the vehicle in March 2022. A Carfax report indicated that the odometer was reported at approximately 75,585 miles on January 28th, 2022, and 55,710 miles on February 11, 2022, reflecting a 20,000 miles difference. The contact stated that the mileage at the time of purchase was unknown. The vehicle currently had approximately 132,064 miles. The issue was reported to the Pennsylvania State Police and the Pennsylvania Attorney General.
After a recall repair (Campaign 9C2) was performed on my vehicle, it developed a hesitation and lack of acceleration issue that did not exist before the repair. 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
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.
After a recall repair (Campaign 9C2) was performed on my vehicle, it developed a hesitation and lack of acceleration issue that did not exist before the repair. 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 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.
Hello, I was driving home from work with my six-month old in the car and the engine stalled while on the Belleville Turnpike. It seized and I was almost rear-ended by a tractor trailer hauling lumber to the lumber yard just a few streets away. I couldn't move the car and was afraid of how to even attempt to secure my car as my daughter was strapped in her car seat. An extremely nice man pulled over and began to flag vehicle to go around me. By this time, I had only my hazard lights on. I was frightened beyond belief having gone through that experience. The car was towed to the dealership who confirmed it was catastrophic engine failure(misfire of a cylinder). They stated initially with my 3rd party warrant that it would be covered and in their words " it was a good thing I had a warranty". Fast forward to two weeks after I check to see what is going on. Things have changed. Now, because I am missing one oil change receipt, they need to be paid $1400, to further corroborate the cause of the engine failure. I haven't paid and honestly don't plan on paying them anything. To date, I have spent over $2,000 on car rental fees since my car is now sitting at the Global Hyundai Dealership.
After my Hyundai dealership performed a recall on emissions my Santa Fe Sport started having problems on cold starts. After it has set for a few hours when I would put into gear and start to driving the car acted as though it was trying to flood out. I have to feather the accelerator and drive very carefully for at least 1/2 - 3/4 miles. This is very dangerous and make me very uncomfortable driving. I took my vehicle back to my Hyundai dealer and the mechanic told me they were waiting for a recall to the recall. How stupid!!! It has been over a month and nothing has been done to fix the problem. Please advise!
NO power till car warms up for 5 minutes. It will be jerky on highway. The gas mileage is going down drastically, I was doing 32 miles to gallon and now it's 22mpg. All this is after the recall we just had performed. I have no power trying to avoid accidents, taking off from stopping. Car smells weird now.
The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated that while driving approximately 35 MPH a loud noise and smoke was suddenly present coming from under the hood of the vehicle and the engine stalled. The vehicle was towed back to the home. The contact indicated that during the failure no warning messages or lights had displayed. The cause of the failure was not yet determined. The local dealer and manufacturer were not yet contacted. The VIN was not available. The failure mileage was 83,000.
am filing a formal complaint regarding an official software update provided by Hyundai that completely corrupted the infotainment/head unit system in my 2017 Hyundai Santa Fe Sport. I purchased this vehicle from CarMax less than three weeks ago. The vehicle came equipped with Hyundai Blue Link, so I contacted Hyundai support to activate the service by pressing the Blue Link button inside the vehicle. Hyundai informed me that my vehicle required a software update because the current system did not contain the necessary software for Blue Link to function properly. A Hyundai representative directed me to Hyundai’s official update website and provided instructions for completing the update. Following Hyundai’s instructions exactly, I purchased and formatted a USB drive, downloaded the update using my VIN from Hyundai’s official website, properly extracted the files, and installed the update into the vehicle. During the installation process, the update failed and corrupted the head unit system. The display now continuously shows “Update Unsuccessful” with Error Code 106. Since the failed Hyundai update, multiple vehicle systems no longer function properly, including the backup camera, Bluetooth, hands-free calling, Blind Spot functionality, radio, map/display system, automatic headlights, and automatic radio shutoff when opening the driver door. I now have to manually operate systems that previously worked automatically. I contacted Hyundai customer support multiple times and was repeatedly transferred between departments. I was incorrectly referred to navigation support even though my vehicle has a non-navigation system. Navigation support confirmed this was a Hyundai issue and stated they could not assist. When I contacted Hyundai again, I explained every step I followed, and the representative acknowledged that I appeared to have completed the update process correctly. Despite Hyundai’s official software causing this failure
I was driving on a main road at 55-60 mph with my daughter and grandchildren in the car and had a sudden loss of power. I was almost hit from behind. The check engine light started blinking. And the car went into limp mode. I had to limp it to the nearest place to safely get off the road so as not to put my family in any other danger.There is not enough shoulder on the road to pull over safely. It was very stressful. Was able to get it in someone's driveway and then eventually towed to Auburn,NY Hyundai/Chevrolet where it is currently. It would not turn over to start again. It does have battery power. I am waiting to hear from the service techs as to what they think is wrong. They advised me that there is a $199 per hour diagnostic fee. I also told them that we noticed metal flakes in the oil when we checked it. I feel I should mention that the vehicle went into limp mode a few weeks ago also and the dealership told me the knock sensor was bad. I had that replaced at that time.
THIS IS AN UPDATE TO EXISTING NHTSA ODI COMPLAINT #11735718 2017 Hyundai Santa Fe Sport, TXXI Theta II engine defect.
