TAKE A BREAK" - the feature prompts the driver to “Take a Break” with that text and a‘Coffee Cup” logo after a certain period of continuous driving. There are instances when turning it off is necessary and Hyundai has removed that option - high distracting false alarm rate. The alert, visual and auditory are intrusive, unnecessary, demonstrate a high false alarm rate leading to frustration and distraction. While designed as a safety feature, it has the opposite effect. The system inaccurately interprets the driver’s behavior as signs of fatigue with alerts popping up at an alarming rate. Perfectly normal and safe driving behaviors see the alert popping up again and again. Further there are environmental interferences - bright sunlight, reflections off glasses, bumpy roads requiring frequent corrections - system interprets these as driver inattention and cannot tell the difference between drowsy driving and navigating a poorly maintained highway. New Hyundai models do not allow the driver to disable the Take a Break alert. “You’re cruising down the highway, minding your own business, alert and focused, when your Hyundai flashes a coffee cup icon and tells you to take a break. Again - this for the third or fourth time in 20 minutes. You’re not tired, not swerving, and frankly, you’re getting annoyed”. The system is disruptive and unsafe as it disrupts the driver activating when the system detects inattentive driving, suggesting breaks even if the driver does not feel fatigued. The alert can illuminate even during short drives of less than 30 minutes. The alert can occur extremely frequently, especially during long drives, which is extremely annoying. The warning can appear shortly after starting a trip and may repeat every few minutes, which is extremely frustrating. It is far more disruptive than safe and helpful.
NHTSA complaint #11758055 — an unverified report by a vehicle owner.
The multifunction/turn signal switch in my Hyundai has failed and causes the left turn signal to operate intermittently. While driving, I am unable to reliably activate the left turn signal when making a left turn or changing lanes. The signal may fail to engage when the turn signal lever is operated, requiring repeated attempts to activate it. College Station Hyundai inspected the vehicle and diagnosed the multifunction switch as the failed component requiring replacement. The replacement component has been identified as Hyundai part number 93400-S1750. I consider this a significant safety concern because the failure prevents me from reliably signaling my intention to turn or change lanes to other motorists. The malfunction occurs during normal operation of the vehicle and creates the risk that surrounding drivers will not know that I intend to turn or change lanes. The vehicle currently has approximately 86,611 miles. I reported the issue to Hyundai Motor America and requested assistance because this is a safety-critical component. Hyundai declined my request because the vehicle is outside the warranty period. I am submitting this complaint because I believe the premature failure of a component necessary for the reliable operation of the vehicle's turn signals may constitute a safety-related defect, and I am requesting that NHTSA document and evaluate this failure.

This complaint concerns a serious, unresolved powertrain/propulsion safety defect in my 2023 Hyundai Santa Fe. While traveling approximately 70 mph, the vehicle suddenly lost propulsion and would not accelerate normally while surrounded by highway traffic.MOST IMPORTANTLY, THERE WAS NO WARNING OR ADVANCE INDICATION. No warning lights, messages, or symptoms appeared before the loss of propulsion. I had no opportunity to anticipate the failure or prepare to safely exit traffic. This placed me and other motorists at immediate risk of a serious or potentially fatal collision.A Hyundai dealership inspected the vehicle and documented DTC P284001, Shift Fork D Position Fault. Despite this documented fault, the underlying safety issue remains unresolved. Hyundai has not identified a permanent correction or established that the vehicle is safe to operate.There has not been another incident because I will not risk another sudden loss of propulsion by driving the vehicle. The absence of another failure does NOT mean the problem is resolved. The vehicle remains available for inspection.I have repeatedly sought assistance from Hyundai and the dealership without a meaningful resolution. Newer information regarding a possible computer reset/relearn procedure has also been presented, but the dealership refuses to perform it.I reviewed NHTSA complaints for 2023 Santa Fe vehicles and found multiple reports describing similar safety symptoms, including sudden loss of propulsion, inability to accelerate, abnormal transmission shifting, and loss of speed. This raises serious concern that this may not be an isolated failure.A vehicle that can unexpectedly lose propulsion at highway speed WITHOUT ANY WARNING creates an extreme crash risk. I respectfully request that NHTSA review the similar complaints, investigate whether a broader transmission/powertrain safety defect exists, and determine whether corrective action is necessary before this results in serious injury or death.

Over the past month, on two occasions my vehicle has emitted gasoline fumes filling my garage, and today my interior cabin smelled like gasoline. Additionally, after warming up, my vehicle experiences acceleration drop/stuttering when accelerating after idling. This happens every day. I took the car to two dealerships (San Tan Hyundai and Chapman Hyundai Scottsdale) and they weren’t able to diagnose the issue.

Windshield breaks with no reason. I have had 2 windshields crack with no sign of any damage. First windshield is within 3,000 miles of owning the car. Replaced one has already cracked and has less than 500 miles. This issue is affecting multiple Sante fe drivers
NHTSA complaint #11754262 — an unverified report by a vehicle owner.
We were notified there was a recall and to schedule an appointment to get the update. We did and it was updated. It hesitated when we drove it the next day and everyday after. WE took it in a second time and was told by our dealer that following the completion of service campaign 9c2 certain vehicles may exhibit a brief hesitation or rough shifting conditions and to let it warm up for 1-3 minutes. We were told that Hyundai is working on it. It has been over a month and it still does it. I now own a 2020 Hyundai Santa Fe vehicle with less than 38,000 miles that is a lemon in my opinion. I am paying for gas to let it run for the 3 minutes and cant sell it or trade it in without a major reduction in price. I feel Hyundai is not being responsible for the damage they have caused to my vehicle.

After having the Service Campaign 9C2 ECU SOFTWARE UPDATE FOR THETA II EMISSIONS IMPROVEMENT, TSB 26-01-013H-2 done, my vehicle started having driveablity issues. On a normal, cold start the engine's RPMs go up really high, so I take my foot of the gas and the revs drop, almost stalling the car, and then the car bucks. I put my foot back on the gas pedal, and the engine revs really high again and takes off. If I try to drive normally, the car bucks and runs rough. My car also revs a lot higher during highway driving, than it did before the update. All of this is also causing terrible gas mileage. My car did nothing like this until I had the 9C2 update.

My 2017 Hyundai Santa Fe (VIN: [XXX]) was brought to Herb Chambers Hyundai of [XXX], in December 2023 to address the Underbody Corrosion Recall/Campaign (9A0). The dealer performed the preventative service. However, the remedy completely failed because the frame was already severely structurally compromised by rust. In early 2024, I relocated to [XXX] with the vehicle. Now 2026, The front subframe sub-assembly deteriorated to a hazardous point, forcing me to spend a large sum of my own money on front-end repairs caused directly by this corrosion. Currently, the rear subframe and rear suspension components are heavily corroded and structurally disintegrated. The vehicle is completely unsafe to drive, presenting an imminent risk of structural collapse and suspension failure while in motion. Hyundai's recall remedy was ineffective and merely masked the rust. The rear subframe (crossmember/cradle) and control arm anchor points are severely corroded, rusted out, and crumbling to the touch, creating an imminent risk of suspension collapse while driving. The extreme corrosion has spread to the metal fuel line the vehicle is unsafe to drive due to the advanced corrosion . Denial of Service by Local Distributor: The vehicle is currently located in the U.S. territory of Puerto Rico. I presented the vehicle and documentation to the local authorized distributor, Sojitz de Puerto Rico (Hyundai of Puerto Rico). As indicated I brought the Vehicle to MVP Hyundai Humacao (XXX) and filed a claim (# XXX) However they never sent a anyone to inspect the vehicle or process a safety claim, claiming they bear no responsibility because the vehicle was imported from the mainland, Because this is a failed federal safety campaign remedy that now poses an immediate threat to my life and public safety, INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After going to the Hyundai dealership for them to perform Service Campaign SC2 on 6/10/26, the engine is a little jumpy for the first minute or two of driving, especially low speeds through my neighborhood.

The airbag sensor is on in the car. When I told the dealership they stated that the sensor is not covered under the warranty even though it was over by a fe hundred miles. None of the airbags will deploy if there is an accident. I don't see why a safety issue is not covered by the warranty. For the dealership to fix it, it is going to be over $800.

We are driving on the highway and the engine just stop working but all lights are still working. I am trying to put gas but it seemed that the engine completely shuts off dangerously without warning. This put my family at risk because there were a lot of big trucks beside us. Theta II 2.0L Turbo engine just stalled I believe this has been around . Can you please help us.

First Failure occurred 7 months after purchase at 5,270 miles on August 1, 2024. The vehicle suddenly went into "Limp Mode" abruptly decelerating to 25 mph with a non-responsive gas pedal. A code reader displayed PO653 Sensor Reference: "Voltage B Circuit High". Dealer found corroded wire to battery and cleaned it. Second Failure: Horn loss to 1 tone. Fixed at 30K mile dealer service on June 12, 2026 and found to have faulty packing resulting in corrosion. At the same standard service the Brake System was flushed. 3rd Failure was 5 days and 437 miles (30,712 miles) after the 30K dealer service. On June 17, 2026 during my early morning commute while merging onto the interstate, alarms began to blare and the gas pedal suddenly became unresponsive. The initial alarms read Blind Spot Failure. Car would not accelerate from 40 mph that it was going coming down the bridge ramp so I took the very close off ramp down from the aqua duct and the console display alert showed "Engine Management System: details: Braking and Body Control System with a recommendation to get "a full system check...TODAY". I brought it to the dealer that afternoon and as of yesterday, 6/26/26 they can find nothing wrong, declaring it an intermittent issue and asked me to come get the car, refusing to continue looking or providing alternate options other than referring me to Hyundai Consumer Affairs.

Hi, I have a 2017 Hyundai Santa Fe sport and I recently went to the dealership to get my brakes done and that day they did the recall 9C2 which is a software update on the engine/transmission and the next morning when I drove my car the rpm’s were going up and my mph wouldn’t go past 15 mph for about a block down the road and the car jerked two times and then drove like normal. I call the dealership let them know about the issue and it’s never been an issue in the past and they set up a appointment I come in and they tell me if it’s not related to the brakes then I’ll have to pay $250.00 for a diagnosis test. Unbelievable I don’t believe this is a coincidence I have taken well care of my car and the past owner as well and the car doesn’t even have 100k miles. I have researched other people in the same situation as me and even read that Hyundai is recommended us to warm up our cars before driving now. It is so frustrating my car was perfectly fine until that recall and they won’t do anything about it.

Vehicle stalled while driving — unsafe loss of power. While driving at normal speed, the vehicle suddenly shut off without warning and the electrical system malfunctioned. I had to pull over and restart car. This created a dangerous situation and could have caused a collision. Prior to this incidenct, the vehicle had intermittent electrical issues during startup (flickering electronics). This is the first time the car has experienced during driving, and is now at the Hyundai dealership. The car has been reported as unsafe to drive. This appears similar to other Hyundai stalling/power loss issues and may indicate a developing safety defect. Requesting investigation.

The rear occupant seat sensor after an update even if there is nothing on the back or on the seat it continues to activate the horn and advising we received a rear occupant alarm. I even deactivate the option and still goes off constantly. I have to leave the car unlocked to avoid the alarm going off.
