2017 Hyundai Santa Fe Sport Problems

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 .

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.

My ABS Lights the triangle with the ! In the middle goes in and off the down hill control light and the sweet control light all go on when the ABS light goes on my oil was completely dry had to add two quarts while the engine was ticking when started and when accelerating it was making a clicking noise I still had 3000 miles before needed an oil change but like I said it was bone dry and then the drivers seat was going back and not wanting to come back up I’ve only had the car 42 days and it’s having all kinds of problems

Engine or sometimes TPS brakes lights on

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.

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.

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)

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.

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.

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.

While driving on US-rt1 in Dinwiddie Va, in my 2017 Hyundai Santa Fe Sport. I was in a collision where a vehicle pulled out in front of me at no fault of my own, and I hit that vehicle going about 47mph. the front nor rear/side air bags deployed. My body slammed into the steering wheel causing severe whiplash as well and contusions to my left shoulder and neck, as well as my wife to be who also sustained injuries to her leg/knee. Had the airbags deployed i would have not made contact with the steering wheel though-out these events.

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.

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.

The vehicle is experiencing a massive paint adhesion failure (white pearl paint), which is peeling off in large sheets from the hood and roof. This is a severe manufacturing defect. At highway speeds, paint flakes fly off, posing a significant safety hazard to other drivers and obstructing visibility. Furthermore, the exposed metal is prone to rapid corrosion, which compromises the structural integrity of the body panels. Despite contacting Hyundai Motor America (Case #XXX), the manufacturer has refused to provide a timely resolution or cover the repair cost of $4,650, as estimated by an authorized dealer."

The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated that while driving over bumps in the roadway, there was an abnormal crunching sound coming from the front driver’s side of the vehicle. Upon inspection, it was discovered that the driver’s side front coil spring had fractured. The vehicle was taken to the local dealer who confirmed the failure and indicated that the coil spring needed to be replaced. The vehicle was not yet repaired. The manufacturer was also notified of the failure. The contact stated that NHTSA Campaign Number: 17V577000 (Suspension) was issued for the VIN of several preceding model years. The failure mileage was 85,000.

The left rear differential completely failed at 25,000 miles. According to the repair shop (Connie & Dicks in Claremont, CA) there was something structurally wrong with the rear differential and it never should have failed like this on a 5 year old car with 25,000 miles. The pinion nut was loose which caused the pinion gear to walk forward and backward in the housing which caused wear on the differential and resulted in catastrophic differential failure.

Engine died at 48k miles. Using a lot of oil. Driver seat belt not working properly. Waiting time for diagnostic 3-12 weeks.

NHTSA RECALL: 17V365000 I HAVE NEVER BEEN CONTACTED BY HYUNDAI REGARDING SEAT BELT ANCHOR ISSUE. I PURCHASED THE VEHICLE JULY 2017 AND WAS NOT INFORMED BY THE COMPANY SELLING THE VEHICLE (BYERS AUTO GROUP, COLUMBUS OHIO) OR THE MANUFACTURER OF THIS RECALL. IF THERE IS A PROBLEM WITH SEAT BELT ANCHOR THIS NEEDS FIXED ASAP.

APPROXIMATELY ONE YEAR AFTER HAVING THE CAR I BEGAN TO NOTICE ISSUES. (18000) I HAVE RETURNED TO THE DEALER FOR MULTIPLE REPAIRS. THE MOST SIGNIFICANT ISSUE IS THE TOE. THE VEHICLE WILL NOT STAY IN ALIGNMENT AND IS WEARING THE TIRES UNEVENLY CAUSING TIRES NEEDING TO BE REPLACED WAY TOO SOON. AFTER HAVING THE CAR ALIGNED I WILL HAVE TO TAKE IT BACK WITHIN A WEEK OR SO FOR ANOTHER ALIGNMENT. I TRAVEL BETWEEN HOUSTON AND AUSTIN FREQUENTLY AND THIS IS A HUGE CONCERN FOR MY SAFETY. AS YOU ARE AWARE REPLACING TIRES IS VERY EXPENSIVE AND POINTLESS IF THE CAR WILL CONTINUE TO WEAR UNEVENLY. I HAVE SENT A CERTIFIED LETTER TO HYUNDAI BUT HAVE NOT RECEIVED A RESPONSE.

MY ISSUE - When making turns at night with the low beam headlights on automatic and switching on the left turn signal the headlights go out for up to 30 seconds then come back on. this is very dangerous when driving in rural or low light areas. Possible headlight switch issue. TAKEN FROM THE INTERNET - I have a 2017 Hyundai Tucson and last year this problem only happened once, but now it has been going on for the past 3 consecutive days. If I have my headlights on or on auto and I use the left signal, the headlights turn off. Only the left, not the right. The display on my dash displays the lights going to off and back to auto or on when the signal has been activated and then stopped
