2017 HYUNDAI SANTA FE SPORT Complaints

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. UPDATE: On May 7, 2026, Hyundai Case Manager acknowledged in writing "Your case is important to us" and "2.4L THETA concerns" for Case #42623761. This is written admission the vehicle has the TXXI defect covered by warranty extension to 120,000 miles. I gave Hyundai 48 hours to provide written authorization for oil consumption test per their TSB 22-EM-003H. After 3 days they are silent. They refuse email communication despite documented language barrier. Current Vehicle Status: - Active DTC P0010 causing loss of power and stalling risk - Oil Consumption: 1 liter per 600km, which is 3x Hyundai failure threshold in TSB 22-EM-003H - 95,772 miles, under TXXI 120,000 mile warranty limit - U.S. Spec vehicle covered by TXXI Warranty Extension Hyundai is violating Magnuson-Moss Warranty Act by refusing to honor written warranty for known safety defect. The P0010 defect causes sudden loss of power while driving. Requesting immediate NHTSA intervention to compel Hyundai to perform warranty repair.

Immediately following the implementation of Service Campaign 9C2 and TSB 25-01-087H - ECU Update for THETA II Emissions Logic Improvement, the vehicle exhibits poor drivability (staggering/missing/hesitation) until the engine warms up. This is most noticeable just prior to the shift from first to second gear.

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

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."

Abs, traction control lights, emergency braking lights on .. tire sensors are bad. Causing intermittent issue with the lights. For 3 years I've been trying to get my ABS/traction control fixed at Hyundai, that dealership refused to acknowledge there was an issue. I had a code from a car place since I live over an hour away and they said they couldn't use it since it wasn't from them. I have an extended warranty there. Went to another dealership and was immediately told it was the tire sensors. That he used to work at the other dealership and they saw it all the time. I now see Palisades have a tire sensor issue. Heck I've been dealing with this for years, and apparently so are many other Hyundai owners, according to this Hyundai employee. Now they're trying to overcharge me and saying my warranty will only cover a quarter of what they want. My deductible is only 100 if I don't get the work done at the original place, the one that said there isn't a problem. I've had it with Hyundai. They are unsafe and don't care about customer service.

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.

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.
