2017 Hyundai Santa Fe Sport

I was driving on the highway in a mountainous area going downhill. The cruise control was on with the speed set at about 80 miles/hour. Then the car was losing speed, the RPM needle started swinging from left and right. I stepped on the accelerator but the car continue losing speed to 40 miles/hour and continue losing speed. I turned on the emergency light to warn the other drivers and was able to move the car to the shoulder and stopped it without an accident. But the cars behind me could have smashed into my car that day and that would be the last day for my mother (in the car at that time) and me. The car had 41000 miles on it and we had the maintenance done just recently. I did not notice anything else abnormal before the incident. We reported the problem to the dealer and have to pay for the dealer to inspect the car. The inspection has been scheduled but not done yet.

UNKNOWN It started with the engine suddenly reducing my speed down to 10 mph while I was driving on the freeway, the check engine light turned on. We then took it to the Hyundai dealership who turned us a way and told us they couldn’t see us for several months. So we were forced to take it to a repair shop who ran a compression test and told us it failed. We were able to speak to the dealership a few days later who asked us to take it in they re ran the test and told us it passed but they needed to do some updates to the knock sensor due to multiple recalls they had failed to inform us on (even though they had conducted an update back in 2019) after this they conducted several oil consumption tests which have averaged a liter or more consumed per 500 miles. During this time the vehicle repeatedly had knocking sounds, warning light flashes, sputtering of the engine, occasional stalling, and marked issues with acceleration from a stop, amongst other concerning issues. We then we’re required to have a combustion cleaning by the dealership, this not only didn’t solve any of the previous issues but increased the oil consumption to as much as 1.5 liters in around 330 miles. The dealership confirmed that the vehicle had been properly maintained and it hadn’t been tampered with but Hyundai continues to refuse to replace the engine. Even though many of the other engines with similar issues have since caught on fire and endangered the occupants. The vehicle continues to jerk when accelerating and consume oil at an alarming rate.

The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated that while driving at an undisclosed speed, the vehicle experienced shaking and vibrating while the accelerator pedal was depressed. The dealer was made aware of the failure; however, the vehicle was not diagnosed nor repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 45,000.

MY CAR HAS STARTED JERKING WHEN UP SHIFTING AND SEEMS TO ONLY BE HAPPENING WHEN THE CAR HAS NOT WARMED UP. THEN TODAY WHILE DRIVING ON THE INTERSTATE AT 78MPH MY CAR LOST POWER. NOT COMPLETELY. ALMOST LIKE SOMETHING "GAVE OUT" AND I LOST THE FORWARD FORCE I WAS GOING. IT ALSO BECAME LOUDER, ALMOST LIKE A LID HUM. WHEN YOU ACCELERATE THE VEHICLE DOES NOT WANT TO GO

TAKATA RECAL: WHILE MERGING ON TO THE HIGHWAY ONRAMP, THE VEHICLE FAILED TO ACCELERATE PROPERLY. IT WON'T GO ABOVE 50 MPH EVEN WHEN I FLOORED THE ACCELERATOR PEDAL. I HAD TO SLOW DOWN AND THEN GRADUALLY ACCELERATE. THIS WAS DANGERS AS I COULD HAVE BEEN REAR-ENDED, SPEED LIMIT WAS 65 MPH. IF YOU HAVE TO GUN-IT, THE VEHICLE FAILS TO REGISTER THE ACCELERATION PROPERLY. IT'S LIKE IT SKIPS A GEAR AND GETS STUCK AT THE LOWER GEAR SETTING. I HAVE NOTICED THAT THIS PROBLEM HAPPENS WHEN YOU FLOOR THE ACCELERATION PEDAL.

WHEN DRIVING IN NORMAL AND SPORT MODE, ON ACCELERATION THERE IS A DELAY AND WHEN THE GAS IS LEFT OFF, THE ENGINE IS REVVING HIGH BUT PROPULSION, SPEED IS DIMINISHED, HAVING A STALL OUT AFFECT AT VARYING SPEEDS. RPM IS HIGH BUT ENGINE IS NOT RESPONDING . THIS HAS HAPPENED WEEKLY AND NEARLY DAILY WHEN DRIVING IN CITY ENVIRONMENT WITH SPEED FROM 30 TO 50 PLUS MILES PER HOUR.

THIS INITIALLY STARTED AROUND 3K MILES. WE THOUGHT THE VEHICLE ADJUSTING TO OUR DRIVING PATTERNS; HOWEVER OVERTIME IT BECAME A CONSTANT PROBLEM. I CALLED THE SERVICE DEPT. & THEY'D NOT HEARD OF THIS OCCURRING. IT'S GETTING MUCH WORSE AND I'M AFRAID TO DRIVE IT. THE VEHICLE RANDOMLY AT NO SPECIFIC SPEED SEEMS TO EITHER GET STUCK IN A GEAR OR TRY TO STALL TURNING LEFT, RIGHT (DRY CONDITIONS) OR AS I'M ON THE HIGHWAY MOVING LANES; NO SPECIFIC MPH. (THIS IS A DRIVING DEATH MACHINE AND FOR SAFETY PURPOSES I REFUSE TO PUT OTHER LIVES AT RISK) THERE'S A 2-4 SEC. DELAY, FORCING ME TO PUNCH THE GAS (MY GRANDFATHER OR FATHER WOULD HAVE STATED; "SOUNDS LIKE SAWDUST IN YOUR ENGINE") TO GET MY VEHICLE TO MOVE; ULTIMATELY A NEAR MISS OF A FATAL INCIDENT ON TWO SEPARATE OCCASIONS AND BECOMING VERY CLOSE TO GETTING T-BONED DUE TO THIS DANGEROUSLY "UNPREDICTABLE & EXTREMELY UNSAFE" VEHICLE. MY HUSBAND WAS FED UP AND TOOK THE VEHICLE INTO THE DEALERSHIP.WE PROVIDED DETAILED EXPLANATIONS OF OUR EXPERIENCES. YESTERDAY RECEIVED BACK FROM SERVICE TECH OUR INVOICE OF SERVICE WORK AND THEY STATE NO PROBLEMS; & UPDATE CAUSE TO RESOLUTION :TSB 17-BR0002 TCS UPDATE. IN NORMAL DRIVING CONDITIONS FROM 5 MPH TO 20MPH THE RPMS SHOULDN'T SUDDENLY INCREASE TO 5K WITHOUT FORWARD MOTION. THIS OCCURS IN NORMAL, ECO, AND SPORT AT SPORADIC TIMES. MY VEHICLE HAS 10,223 MILES THIS MORNING.I SPOKE WITH HYUNDAIUSA & INQUIRED OF A BUYBACK FOR VEHICLE CONSIDERING THE SERIOUSNESS OF THE VEHICLE'S SAFETY AND BECAUSE THE SERVICE TECHNICIAN STATED THERE'S NO FIX NOW OR IN THE NEAR FUTURE. AN ENGINEER FROM HYUNDAI CORP WOULD HAVE TO COME AND THERE'S NO IDEA WHEN (?). SO I RESPECTFULLY REQUEST AN INVESTIGATION INTO THE SERIOUSNESS OF THIS SAFETY. IF THERE'S ANY POTENTIAL OF PREVENTING LOST LIVES OF CHILDREN AND BABIES, PLEASE HELP.

I'M STOPPED AT A STREET, WAITING TO TURN ON A MAIN ROAD. I JUST HAVE A STOP SIGN, BUT THE CROSS TRAFFIC DOESN'T HAVE TO STOP. I START TO TURN OUT WHEN THERE'S AN OPENING, AND MY CAR STALLS FOR A FEW SECONDS. SOMETIMES IT'S LONGER, SOMETIMES IT'S SHORTER. THIS HAS HAPPENED MULTIPLE TIMES. IT MY CAR DOESN'T GO QUICK ENOUGH, I COULD GET HIT. I'VE NOTICED THIS IS THE WORST WHEN I HAVE IT IN ECO MODE. THIS EXACT THING HAPPENS WHEN I'M ALSO TRYING TO ACCELERATE ONCE I'VE MERGED ONTO A HIGHWAY. IT'S LIKE MY CAR IS STOPPING WHEN I'M TRYING TO ACCELERATE TO GET TO THE PACE OF THE TRAFFIC ON THE HIGHWAY.

I BOUGHT MY CAR IN JULY OF 2016. SINCE THEN I HAD ISSUE WITH THE ACCELERATION. SOMETIMES CAR TAKES LONGER TO START FROM THE STOP POSITION AND WHEN IT STARTS, IT JUST ACCELERATES. ON OTHER OCCASIONS, THE CAR FEELS LIKE STALLING WHILE DRIVING AND THEN PICK UP THE SPEED AGAIN. THIS IS AN ONGOING ISSUE AND I HAD BOUGHT TO THE SALES PERSON'S KNOWLEDGE AT THE BEGINNING, WHEN HE DROVE AROUND TO FEEL ABOUT THE SAME, IT DIDN'T OCCUR AT THAT TIME. BUT, EVERY NOW AND THEN THIS SEEMS TO BE THE ISSUE WITH ME.
