As I would be driving down the road, most of the time when getting up to speeds of either 25-30mph or 55-60mph is when the dash board lights up check BSD detection system failure, then it will rev out rpm’s to 5,000-6,000 then lose power to accelerator. I also notice on the dash board where the panel for your selected gear displays is blank and doesn’t show whether you are in park,drive neutral, ECT. After this occurs I can not drive it any longer until I safely stop the car (most of the time on a busy highway or country road Highway where once this happens it becomes dangerous due to the power loss in the accelerator) and put it in park, I’ve tried to put the vehicle in park, once fully stopped, and try to put it back into drive but the shifter is locked into park and will not let me shift the vehicle, I then have to shut the vehicle completely off and open the driver door to get the backup power cut off as-well to have zero power to the vehicle. Once that is completed I then Re-Start the vehicle where it operates normally again, this situation happens at least twice a week if not 3-4. It sometimes has put my passengers and myself at risk of getting into accidents or struck by other vehicle on the road. my vehicle is still under a warranty through the dealership I purchased it from, but when I ask them about it they say that because there is no prompt on the dash once I get there that they cannot do anything about it, nor do they allegedly know why it’s happening, I’ve asked a few other mechanics I know and they say that they have seen this malfunction before with this vehicle and usually it is a transmission sensor? Or a transmission speed sensor issue? I then relay this message back to the dealer ship and they still act like they don’t know what it is, I truly believe that the dealership just doesn’t want to deal with the issue and I only have 2-3000 miles left under their warranty, I do enjoy the vehicle and respect Hyundai for their great customer service.

Owner: [XXX] VIN: [XXX] Vehicle: 2014 Hyundai Santa Fe Sport My daughter purchased this vehicle in April 2025 from a licensed Chrysler dealership. On [XXX], the engine suddenly seized while driving, without warning, and would not restart. This VIN was part of Recall 17V-226 (Hyundai Campaign 162). Dealer records show the recall was closed with inspection only (“engine inspection, oil, dipstick”), not an engine replacement. The failure matches the defect description of the recall (bearing wear from restricted oil flow). Hyundai is refusing to repair it, claiming sludge and “maintenance neglect,” despite my daughter only owning it for 5 months and having an oil change at Hyundai in May 2025. This engine failure proves the prior “inspection” remedy was ineffective. Hyundai is also denying coverage under the lifetime warranty extension (TXXI), which explicitly applies to subsequent owners for bearing failures. This is a serious safety issue. My daughter lost power in traffic, and the vehicle is still unrepaired. This complaint is being submitted on behalf of the registered owner, [XXX] , by her mother [XXX] , who is the primary contact.

The engine was replaced under a recall related to an engine knock code. About two weeks later, the vehicle lost all power while driving. The dealership confirmed a failure in the high-pressure fuel line and that the turbo had failed at the same time. The same visit revealed oil leaks, and shortly after, the vehicle began emitting white and black smoke. Their technician stated the failures were due to “consequential damage from engine failure.” The problems have continued to return, and I’ve been told the vehicle is unsafe to drive. Hyundai is now refusing to fully cover the cost of repair, offering only 15% off, despite all of the damage being directly linked to the replacement engine. I transport children in this vehicle. My safety and theirs have been at risk multiple times because of these unresolved and ongoing failures.

The contact owns a 2014 Hyundai Santa Fe Sport. The contact stated that the low oil warning light was illuminated, and the vehicle displayed a slight hesitation while shifting gears. The contact took the vehicle for an oil change and there was only a quart of oil in the engine. The certified mechanic informed the contact that the vehicle was consuming an excessive amount of engine oil. The vehicle was taken to the dealer; however, the mechanic found no failure. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 76,000. The contact stated that the Hyundai dealership required another oil change for the vehicle despite the vehicle recently having one done. The manufacturer will not be covering any costs according to the contact.

I WAS DRIVING DOWN THE ROAD ABOUT A WEEK AFTER THE DEALER SUPPOSEDLY FIXED TWO RECALLS WITH THE ENGINE ON MY 2014 HYUNDAI SANTA FE SPORT BASE. SUDDENLY, AND WITHOUT ANY AUDIBLE WARNING, MY ECM LIGHT CAME ON AND MY VEHICLE STARTING LUNGING AND LURCHING FORWARD LIKE IT WAS ABOUT TO STALL. I PULLED OVER AND READ THE MANUAL, AND IT NOTED THAT IT WAS THE ECM SENSOR AND THAT I SHOULD IMMEDIATELY DRIVE THE VEHICLE TO THE DEALERSHIP, SO I DID. DRIVING THERE, I WAS ONLY ABLE TO MAINTAIN A SPEED OF 60 MPH ON THE INTERSTATE, WHICH PUT ME AND MY 8 -YEAR-OLD DAUGHTER IN DANGER FROM FASTER-DRIVING CARS, ESPECIALLY SINCE IT WAS A TORRENTIAL DOWNPOUR. ANY TIME I STOPPED OR SLOWED DOWN, THE ENGINE WOULD SHUTTER LIKE IT WAS ABOUT TO STALL AND THEN WOULD GET BETTER JUST PAST 10-20 MPH UNTIL I APPROACHED 60 AGAIN, WHERE IT WOULD NOT ACCELERATE AGAIN. WHEN I GOT TO THE DEALERSHIP, THEY IMMEDIATELY KNEW THE PROBLEM AND ORDERED A KNOCK SENSOR HARNESS. HOWEVER, IN READING THE VARIETY OF LAWSUITS, ISSUES, AND SERVICE CAMPAIGNS, IT APPEARS AS THOUGH HYUNDAI IS KNOWINGLY ALLOWING PEOPLE TO CONTINUE DRIVING CARS THEY KNOW ARE DEFECTIVE, THUS PUTTING US AND OUR CHILDREN'S LIVES IN JEOPARDY. THESE VEHICLES NEED TO BE RECALLED AND HAVE ALL OF THE ENGINES AND RELATED PARTS REPLACED, OR THEY NEED TO BUY THE VEHICLES BACK AT ORIGINAL MSRP SO WE CAN PURCHASE A FUNCTIONAL, SAFER VEHICLE.

THE VEHICLE LOST POWER WHEN ACCELERATING TO GO ON INTERSTATE, IT JUST HAD NEW SOFTWARE PUT IN.I WENT TO THE DEALER RIGHT AWAY. THEY SAID THAT THEY COULD NOT WORK ON IT TILL THE NEXT DAY. I CALLED HYUNDIA AND THEY KNOW ABOUT IT. IDO NOT THINK THIS VEHICLE SHOULD BE ON THE STREET. THEY SHOULD FIX THE PROBLEM WITH THE CONNECTING ROD, NOT SOFTWARE.

MY VEHICLE WAS INVOLVED IN THE ENGINE RECALL WHICH CAUSED THE VEHICLE TO COMPLETELY SHUT DOWN DUE TO ENGINE FAILURE. AFTER HAVING THE ENGINE REPLACED BY A HYUNDAI DEALERSHIP, THE VEHICLE CONTINUES TO INTERMITTENTLY LOOSE POWER WITHOUT NOTICE. ALTHOUGH, THE TACHOMETER READS 7000 RPM, THE SPEED IS 20 MPH WITH THE PEDAL TO THE FLOOR BOARDS. THIS HAPPENS WITHOUT NOTICE AND HAS HAPPENED ON INTERSTATE HIGHWAYS WITH CARS SPEEDING BUY! WE HAVE TO PULL OVER AND SHUT IT OFF AND THEN RESTART. THEN IT WILL BE FINE TIL NEXT THE NEXT TIME. THE LOCAL HYUNDAI DEALERSHIP HAS NOT BEEN ABLE TO CORRECT THE PROBLEM ALTHOUGH THEY HAVE REPLACED SEVERAL THINGS. IT IS AN ONGOING PROBLEM.
