2017 HYUNDAI SANTA FE Vehicle Speed Control Problems

Twice my car's gear shifter went from Drive to the right hand side of the gear box. 90% or more of the power cut out immediately creating a massive safety issue. In both instances, i was pulling into traffic after making complete stops at stop signs. The first time, i turned left, the second time I turned right. The shift was untouched by me as it is not a stick shift car. Hyundai charged me close to $400 for the privledge of telling me that I or something bumped the shifter to the right. Also they claim that the shifter is designed to go into low gear if it does go to the right. a low gear should provide more power not cut it out. They refuse to fix the issue, but wanted me to bring it in so they could duplicate a problem that has occurred twice in four months.

The turbocharger failed on my 2017 Hyundai Santa Fe Sport 2.0T. It is still on the vehicle and available for inspection upon request. The turbo failure caused a severe loss of engine power, making acceleration dangerously slow and unpredictable, especially when merging onto highways or passing vehicles. This sudden reduction in power could have caused a rear-end collision or made it impossible to avoid faster-moving traffic. Yes. The failure was confirmed by two independent service centers: Mavis Tires and Brakes, and Tires and Trust in Pensacola, FL. Both observed loss of turbo boost and excessive oil consumption consistent with turbocharger failure. Yes. The vehicle was also inspected by Allen Turner Hyundai in Pensacola, FL. They did not detect the failure during their inspection, but the issue persisted and was documented by the other two shops. The check engine light came on around 118,000–119,000 miles. After that, the turbocharger lost significant power, making the vehicle unable to accelerate normally. At the same time, the engine began consuming oil at an abnormally high rate, requiring frequent top-offs between oil changes. This suggests internal oil seal failure in the turbo or related component issues. These symptoms are consistent with failed turbocharger bearings or seals, oil starvation, or blocked oil lines causing overheating and damage. Such failures can release oil and metal debris into the intake and exhaust systems, risking further engine damage or even fire. Hyundai previously issued a software update (KSDS) to detect early bearing wear in these engines, which my vehicle received in 2019 (Service Campaign 953). Despite this, the turbo failure still occurred, suggesting the underlying design or manufacturing issue may not have been fully resolved. I am requesting that NHTSA investigate this pattern of failures, given the safety risks of sudden power loss and potential fire hazard from oil leaks.

The engine seized due to an issue with the oil plug and another part, leading to a lack of oil in the system. The vehicle is currently with Hyundai and available for inspection upon request. How Safety Was Put at Risk: While driving on the highway, I suddenly lost acceleration (below 40mphs). I was forced to pull over to the left side of the highway where it was shallow, where I risked being hit by passing vehicles until there was a safe break in traffic, allowing me to maneuver to an exit. This created a hazardous situation for both myself and other drivers. Reproduction or Confirmation of the Problem: The issue has been confirmed by an independent automotive technician, who diagnosed the problem as a blown engine caused by a lack of oil. The vehicle is now with Hyundai for further inspection. Inspection by Others: The vehicle has been inspected by an independent service center and is currently being inspected by Hyundai. No other parties, such as the police or insurance representatives, have been involved. Warning Lamps or Messages Prior to Failure: The only warning sign prior to the incident was the check engine light blinking at the time of the failure. There were no other warning lamps, messages, or symptoms before the engine seized. The vehicle was within the oil range limit of 7,500 miles at the time of the incident. Additional Notes: The incident occurred suddenly, without prior warning or indication of an issue. Based on the diagnosis and known issues with the oil plug, I believe this failure was caused by a defect.

The traction control system engages too frequently and makes the vehicle unable to accelerate and far too long to disengage, endangering my family during right turns onto lanes with traffic. the traction control system will engage even when there is no loss of traction, only a moderate acceleration with some turn angle. this has caused near accidents about once a month, that both me and my wife experience. there are no active recalls. all recall work was completed last year. this issue has persisted for the length of my ownership, last occuring only about week ago, and about once to 2 times a month.

A knocking noise from the engine that increases in frequency as the engine rpm increases. Reduced power and/or hesitation and vibration. Illumination of the “check engine” light in the instrument cluster. Illumination of the “engine oil pressure” warning lamp. My car will drive up to maybe 37mph and then the engine will seize up and go into safety mode and it becomes inoperable. THIS is a death trap if we suddenly stall out on the highway or at a higher rate of speed!!!! The dealership is basically saying oh well, it is out of warranty. I just bought this car from Banister Nissan on 6/5/2023. Less than 60 days ago.

The contact owns a 2017 Hyundai Santa Fe. The contact stated while driving approximately 30 MPH, the accelerator pedal became inoperable when depressed and the vehicle stalled. The contact stated that a unknown warning light illuminated. The vehicle failed to accelerate and coasted downhill into a parking lot. The vehicle was towed to the local dealer where it was diagnosed and determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was contacted but no additional assistance was provided. The failure mileage was approximately 83,000.

My engine had been using oil at a very fast rate and I was just told that hyundai consume a lot of oil. I have had this car since 77k miles and have issues ever since I bought it. At first I had issues with it not accelerating on the interstate and then it would randomly stop while I was driving, almost like a car hiccup. I took it to the dealership, and other car shops and no one found anything wrong. Finally two weeks ago, I was on I85 and my car was driving really roughly and idling roughly as well. No lights came on until it started to decelerate on the interstate to 30 miles an hour and I had to pull off to the side of the road. Then a bunch of different lights came on and I turned it off and it wouldn't turn back on. I had it towed to the dealership, and they stated I had a bad engine, and Hyundai may replace it but it will take the shop 4-6 months to even take the engine apart to see whats happening. I'm out of a car for at least 4 months probably more, and there is nothing I can do. The mechanic is thinking there is an issue with the bearing.

Vehicle spontaneously caught on fire in the engine compartment while driving in a parking lot. Within 30 minutes, the vehicle was incinerated down to the frame. Prior to this incident, a warning had flashed on the message center that the adaptive cruise control system was being disabled. It is pending insurance inspection and we are trying to contract Hyundai. The police report is not available yet, but is with the Faribault, MN, Police Department and is #[XXX]. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

2017 Hyundai Santa Fe. While driving, the vehicle stopped accelerating. The vehicle operated appropriately until half way through the drive. At stops, it would take several seconds (30ish) for the car to go about 20 mph (rough estimate). The car would not go above 50mph, and this took a few minutes to reach with the gas pedal all the way down. I parked the car and had it towed. After approximately a month at the dealership, the dealership text that there was a hole in the valve cover and that the engine would also need to be replaced. They did not say what was wrong with the engine and later stated, also via text, that to do a diagnostic it would be $350. I purchased the car used with approximately 45000 miles 10 months prior. At the time of the incident, there were 62000 miles on the vehicle. They stated that it would not be covered under warranty because I was not the original owner. I purchased the extended warranty at the time of purchase. They then filed a claim with that policy and we are awaiting an inspector to look at the vehicle. There were no warning lights prior to the issue. My family, husband and 3 children were in the car and it was dangerous because we were on a busy road and the car would not go to the speed of traffic. We are awaiting an inspector to look at the vehicle. The vehicle is currently still at the dealership. If requested, I am willing to have the car inspected. The incident occurred 5/12/2022.

I OWN A HYUNDAI 2017 SANTA FE. I, MY HUSBAND, AND MY DAUGHTER ARE EXPERIENCING (FROM THE TIME OF PURCHASE & REPORTED TO THE HYUNDAI DEALER) A SERIOUS & DANGEROUS LAG WITH ACCELERATION. THIS HAS HAPPENED NUMEROUS TIMES, THE CAR HESITATES BADLY WHEN COMING OUT OF TURNS AND ATTEMPTING TO ACCELERATE...JUST SHORT OF COMING TO A STOP. IT IS VERY DANGEROUS WHEN PULLING INTO TRAFFIC AND APPEARS TO BE GETTING MORE FREQUENT. I HAVE FOUND SEVERAL FORUMS REPORTING THE SAME ISSUES. WILL HYUNDAI FIX THIS ISSUE?

WHILE DRIVING MY 2017 HYUNDAI SANTA FE SPORT 2.0T TO ENTER THE FREEWAY, THE CAR WOULD NOT ACCELERATE NORMALLY. IT STARTED TO SHAKE AND FELT LIKE THE ENGINE WAS "MISFIRING" AFTER SEVERAL MINUTES, I WAS ABLE TO GET UP TO 60MPH. I TRIED TAKING MY FOOT OFF OF THE ACCELERATOR AND PRESSING IT AGAIN BUT IT WOULD ONLY LOSE SPEED AND THEN I'D HAVE TO WORK MY WAY UP TO 60 MPH. I WAS TRAVELLING STRAIGHT AND ON A FLAT ROAD. ENGINE LIGHT WOULD COME ON WHEN FOOT WAS ON ACCELERATOR, THEN IT WENT OFF. ONCE I WAS OFF THE FREEWAY AND TRIED TO MAKE A RIGHT TURN FROM A STOP, CAR WOULDN'T ACCELERATE GOING UP THE INCLINE AND THE CAR BEHIND ME ALMOST HIT MY TAIL END. FINALLY,I TURNED LEFT TO GO UP THE HILL TOWARD MY HOUSE, I COULD ONLY GET UP TO 15 MPH BUT RPMS WERE BETWEEN 3500-4000. LUCKILY THERE WAS NO TRAFFIC BEHIND ME BUT I WAS AFRAID I WASN'T GOING TO MAKE IT UP THE STREET OR THAT SOME CAR WOULD COME UP BEHIND ME AND MY CAR WOULD STOP. IN ORDER FOR A CAR TO BE SAFE IT NEEDS TO BE RELIABLE IN ACCELERATION AS MUCH AS BRAKING AND STEERING! I HAVE AN APPOINTMENT AT THE DEALERSHIP DAY AFTER TOMORROW.

Mileage: 48,500

DURING ACCELERATION FROM A STOP SIGN/RED LIGHT OR TURNING THE ENGINE HESITATES FOR APPROXIMATELY 5 SECONDS AFTER SEVERAL TRIES BEFORE REACHING DESIRED SPEED. WHEN USING CRUISE CONTROL ON FREEWAYS THERE IS A 10 TO 15 SECOND DELAY WHEN ACCELERATING OR PASSING ANOTHER VEHICLE WHICH IN ONE INSTANCE CAUSED A NEAR ACCIDENT ON A HIGH SPEED FREEWAY. MY VEHICLE SLOWED DOWN CAUSING OTHER VEHICLES GO AROUND ME PASSING FROM THE RIGHT SIDE LANE. THESE HESITATIONS HAVE CAUSED ME SEVERAL NEAR ACCIDENTS AND MAKES ME NOT FEEL CONFIDENT WHEN DRIVING THIS CAR. I HAVE TAKEN THE VEHICLE TO THE DEALERSHIP ON MANY OCCASIONS AND THEY REPORT NO ERROR CODES SHOW UP AND, THE MECHANIC CANNOT DUPLICATE THE PROBLEM. HOWEVER, THE DEALER REPLACED THE TRANSMISSION EARLIER THIS YEAR. THERE HAS BEEN NO IMPROVEMENT. I HAVE REVIEWED MANY OTHER COMPLAINTS OF THIS HESITATION PROBLEM. WILL IT TAKE DEATH REPORTS TO HELP US OWNERS? MY ISSUE BEGAN IN 2018 RIGHT AFTER PURCHASE AND THE PROBLEM IS OCCURRING MORE OFTEN NOW. NO HELP IS IN SIGHT WHEN HYUNDAI AND THE DEALERSHIP REFUSES TO ADMIT THE PROBLEM AND MAKES ME AND OTHER OWNERS FEEL LIKE WE DON'T KNOW OUR VEHICLES OR OUR OWN MINDS!! WE NEED HELP BEFORE A DEATH OCCURS NOT AFTER!!

TL* THE CONTACT OWNS A 2017 HYUNDAI SANTA FE. THE CONTACT STATED THAT WHILE DRIVING AT AN UNDISCLOSED SPEED, THE VEHICLE DECELERATED INDEPENDENTLY AND STALLED WITHOUT WARNING. THE CONTACT STATED THAT THE FAILURE RECURRED SEVERAL TIMES AND WAS TOWED TO MILLER HYUNDAI LOCATED AT (4455 VESTAL PKWY E, VESTAL, NY 13850) WHERE UNKNOWN REPAIRS WERE PROVIDED HOWEVER, THE FAILURE PERSISTED. THE VEHICLE WAS REPAIRED A TOTAL OF 6 TIMES BY THE DEALER. THE MANUFACTURER WAS CONTACTED AND INFORMED OF THE FAILURE AND OFFERED MINIMAL MONETARY ASSISTANCE. THE FAILURE MILEAGE WAS 29,792.

ON THE INTERSTATE, PRESSED THE GAS PEDAL AND THE VEHICLE DID NOT AND WOULD NOT ACCELERATE. I TRIED MULTIPLE TIMES. RPM WENT UP TO 5000 BUT SHIFTING THE TRANSMISSION INTO SPORTS MODE AND DOWNSHIFTING AND UPSHIFTING MADE NO DIFFERENCE IN THE SPEED OF THE VEHICLE. SPEED REMAINED THE SAME, ENGINE ROARED AS IF IN NEUTRAL. I PULLED OFF THE INTERSTATE, CUT OFF THE VEHICLE FOR SEVERAL MINUTES, RESTARTED THE VEHICLE, RETURNED TO THE INTERSTATE AND COULD ACCELERATE. THIS HAPPENED MULTIPLE TIMES IN 2017 AND 2018 BOTH ON THE HIGHWAY AND CITY STREETS. IN 2018, TAKEN TO PEARSON HYUNDAI AND COULD NOT BE FIXED BECAUSE NO ERROR CODES. AFTER A DANGEROUS, IDENTICAL INCIDENT ON THE INTERSTATE IN MAY 2019, TAKEN TO PEARSON HYUNDAI. THEY PERFORMED A TCU AND ECU SOFTWARE UPDATE MAY 21, 2019. THIS LATEST INCIDENT IS A REPEAT OF THE MAY 2019 PROBLEM. THE PROBLEM IS RANDOM AND UNPREDICTABLE BUT OCCURS ON BOTH HIGHWAY AND STREET SPEEDS. THE INABILITY TO ACCELERATE WITHOUT WARNING WILL EVENTUALLY CAUSE AN ACCIDENT. WE ALSO OWN A 2016 SANTA FE SPORT TURBO AWD THAT HAS NOT HAD ANY OF THESE ACCELERATION PROBLEMS. CHANGES WERE MADE IN THE 2017 MODEL YEAR TO THE ENGINE AND TRANSMISSION THAT ARE IMPACTING ACCELERATION.

Mileage: 31,000

WHEN I DRIVE GOING STRAIGHT AT ABOUT 40 TO 48 MPH ON ECO MODE OR ANY DRIVE MODE THE CAR JUMPS/ JERKS LIKE IT SHIFTS INTO A LOW GEAR AND THEN GOES BACK INTO A HIGH GEAR WITH NO HEAVY ACCELERATION. IF I HAVE IT ON CRUISE CONTROL AT 45MPH IT WILL KICK BACK AND FORTH OCCASIONALLY AS IF I WAS SLAMMING ON THE GAS PEDAL THEN SLIGHTLY ON THE BREAK BUT QUICKLY.

Mileage: 30,700

WHEN MAKING RIGHT TURNS, MY CAR SUDDENLY STOPS ACCELERATING FOR A FEW SECONDS. THIS USUALLY HAPPENS WHEN EITHER THE CAR IS STOPPED AND THEN I GO TO TURN, OR TURNING AT A VERY LOW RATE OF SPEED AROUND A CORNER. WHEN I PUSH DOWN ON THE GAS PEDAL TO GO, IT TAKES OFF ABRUPTLY OR WITH A SURGE. THIS IS CONCERNING, ESPECIALLY IF A CAR IS FOLLOWING BEHIND ME. I ALSO NOTICE IT WHEN STOPPED AT A LIGHT, GOING STRAIGHT ALSO BUT NOT NEARLY AS MUCH AS WHEN I AM MAKING A TURN.

Mileage: 30,000

WHILE TURNING RIGHT OUT OF A PARKING LOT ONTO A TWO LANE ROAD, THE VEHICLE SUDDENLY STOPPED ACCELERATING FOR 3-5 SECONDS AS A TRUCK WAS BEARING DOWN ON US. THE POSITION OF THE GAS PEDAL MADE NO DIFFERENCE. THE ENGINE WAS RUNNING AT AN IDLE WITH ZERO RESPONSE FROM PEDAL INPUT. WHEN IT DID FINALLY ACCELERATE, IT LURCHED FORWARD AS THE PEDAL WAS PRESSED TO THE FLOOR. WE ARE ALSO EXPERIENCING WHAT COULD BE DESCRIBED AS A SHUDDER WHEN DECELERATING TO A STOP. IT TYPICALLY SEEMS TO OCCUR BETWEEN 20-12 MPH. IT FEELS AS IF THE ENGINE IS STUMBLING OR IT IS HAVING TROUBLE DOWNSHIFTING SMOOTHLY.

I WAS DRIVING FROM KELLOGG, MN TO WINONA, MN AND I STOPPED AT LARK TOYS. WHILE JOINING MN HIGHWAY 61, TURNING RIGHT I HAD TO ACCELERATE. I WAS IN SPORT MODE AND VEHICLE ACCELERATED AND ALMOST STOPPED. LUCKILY NO ACCIDENT OCCURRED, I HAD MY 17 MONTH KID AND MY WIFE IN THE CAR. CAR AFTER THAT GAVE CHECK ENGINE LIGHT WARNING AND IT WOULD NOT ACCELERATE. I CHANGED TO ECO MODE AND THEN IT SLOWLY STARTED TO ACCELERATE, BUT AT ABOUT 20 MILES AN HOUR IT JERKED AGAIN, BUT I PRESSED ACCELERATE HARD AND IT SUSTAINED SPEED. BUT IT WONT GO OVER 65 MILES AN HOUR. I SLOWLY MADE IT HOME. BUT I TRIED TO DRIVE AGAIN AND SAME ISSUE. CALLED HYUNDAI CUSTOMER SUPPORT AND THEY REFUSED TO ROCHESTER AS IT IS 46 MILES AND THEY ONLY SUPPORT 20 MILES OR LESS TOW. MY CAR IS STILL UNDER MANUFACTURE WARRANTY AND YET WORST SERVICE. I ALMOST GOT KILLED TODAY WITH MY 17 MONTH TODDLER

FAILURE TO ACCELERATE FROM A STOP POSITION. PULLED OFF THE HIGHWAY ONTO THE OFF RAMP. CAME TO A STOP THEN TRIED TO TURN LEFT. VEHICLE BARELY MOVED AND HAD TO ACCELERATE TO OVER 2500 RPM AND SEVERAL SECONDS LATER TO GET THE VEHICLE BARELY MOVING. PULLED OFF THE ROAD, PUT THE VEHICLE INTO MANUAL SHIFT MODE TO FIND THE TRANSMISSION IS LOCKED INTO 4TH GEAR AND CANNOT BE DOWNSHIFTED TO 1ST. VEHICLE CONTINUED TO BE LOCKED INTO 4TH GEAR AFTER EACH STOP. TURNING OFF THE VEHICLE AND RESTARTING TEMPORARILY CORRECTS THE PROBLEM. POTENTIAL MAJOR SAFETY ISSUE.

PURCHASED NEW 7/172017 SANTA FE ULTIMATE 2.0T. THIS SUV DOES NOT ACCELERATE AND LAGS ON AN INTERMITTENT BASIS HAPPENS AT A LOWER SPEED AND FROM A STOP. VERY DANGEROUS WHEN MAKING A TURNS AND ENTERING FREEWAY OR TRAFFIC CICLES (ROUNDABOUTS) WHEN DEPRESSING ACCELERATOR AND YOUR VEHICLE SLOWLY MOVES FORWARD AND FAILS TO ACCELERATE TO THE REQUIRED SPEED YOU ARE REQUESTING FOR A SECOND OR MORE. NOW YOU HAVE PLACED YOURSELF IN A VERY DANGEROUS POSITION BECAUSE OFTHIS VEHICLES INABILITY TO RESPOND. THEN ALL OF A SUDDEN IT TAKES OFF. DOES NOT HAPPEN EVERY TIME BUT IS FREQUENT ENOUGH TO BE CONCERNED. HAS HAPPENED CONTINUALLY SINCE NEW. MY WIFE LOVES THE VEHICLE BUT IS AFRAID TO DRIVE IT..NO ONE SEEMS TO KNOW WHAT THE PROBLEM IS BUT THERE ARE CERTAINLY ENOUGH COMPLAINTS THAT SOMEONE SHOULD INVESTIGATE AND GET AFTER HYUNDAI TO FIX THE SITUATION BEFORE SOMEONE GOD FORBID IS KILLED.. OR THAT'S UNFORTUNATELY WHAT IT WILL TAKE TO RESOLVE THIS SERIOUS DEFECT. I LOVE THE VEHICLE ESPECIALLY THE TURBO BUT IT'S SCARY.

IT TRIES TO STALL OR HESITATE WHEN MAKING TURNS I LIVE IN CHICAGO AND DRIVE IN TRAFFIC WHEN TURNING INTO TRAFFIC IT SEEMS TO HESITATE FOR 2 OR 3 SEC BEFORE ACCELERATION II AM AFRAID TO DRIVE THIS VEHICLE IN TRAFFIC FROM FEAR WHEN MAKING A TURN I WILL. CAUSE A CAR ACCIDENT

2017 HYUNDAI SANTE FE SPORT AWD - PURCHASED IN OCT 2017. CURRENTLY HAVE 7525 MILES ON VEHICLE. I NOTICED ACCELERATION HESITATION IMMEDIATELY AFTER MAKING IN CITY TURNS (FROM BOTH STATIONARY AND IN MOTION TURNS) AS WELL AS WHEN GETTING ON HIGHWAY (IN MOTION). I AM RETIRED AND DO NOT DRIVE SANTE FE VERY OFTEN. THE PROBLEMS WITH ACCELERATION AFTER MAKING STATIONARY AND IN MOTION TURNS AND GETTING ON HIGHWAY HAS ALWAYS BEEN PRESENT SINCE DAY OF PURCHASE. I HAVE NOTICED THE PROBLEM HAS BECOME MORE PREVALENT AFTER TAKING A 1000 MILE ROAD TRIP THIS PAST AUGUST. THE ACCELERATION/ HESITATION AFTER TURNING IS MORE NOTICEABLE AND IS BECOMING CONCERNING BECAUSE I HAVE TO PRESS PETAL TO FLOOR TO GET THE SANTE FE TO ACCELERATE PROPERLY TO GET OUT OF WAY OF ON COMING TRAFFIC. HESITATIONS/ACCELERATION PROBLEMS OCCURS AFTER TURNING AND WHEN ENTERING A FREEWAY. VERY POOR ENGINE PERFORMANCE GIVEN THE VEHICLE COST OF $35,000. I OWNED A 2011 HYUNDAI SONTA FOR 6 YEARS AND HAD THE SAME 2.4L ENGINE AND I NEVER EXPERIENCED ANY ENGINE HESITATION LIKE I AM NOW WITH THE 2017 HYUNDAI SANTE FE SPORT AWD.

WITH EXCELERATION INTO ONCOMING TRAFFIC HAS ABOUT A 2-3 SECOND PAUSE AND ALSO WHEN PASSING. HAS ALMOST CAUSED ME SEVERAL T BONE ACCIDENTS. WHEN TAKING OUT FROM SOMEWHERE THE VEHICLE HAS SET AND COOLED IT TAKES ABOUT 5 SECONDS TO REACH APPROPRIATE SPEED. THIS DOES NOT OCCUR ALL TIMES LIKE THE ABOVE COMPLAINT. OUTSIDE NOISE IS EXTREMELY LOUD. NOT A QUIET DRIVING CAR BY ALL MEANS. AIR NOISE AROUND DOORS ETC

SMART CRUISE CONTROL FAILS TO BRAKE INTERMITTENTLY. IT IS DESIGNED TO MATCH SPEED WITH THE CAR IN FRONT OF IT. IT USUALLY WORKS FINE, UNLESS ANOTHER VEHICLE CUTS IN FRONT, EVEN IF THERE IS ENOUGH TIME TO BRAKE. I HAVE TO SLAM ON THE BRAKES MANUALLY TO AVOID AN ACCIDENT. THIS HAS HAPPENED ON MULTIPLE OCCASIONS. I NOW FEAR USING THE CRUISE CONTROL AT ALL, AS IT DOES NOT PERFORM CORRECTLY 100% OF THE TIME. THE DEALER SAID THEY COULD FIND NOTHING WRONG, BUT THIS IS A VERY REAL ISSUE THAT PUTS MY FAMILY AT RISK. THEY HAVE NOW CALLED IN A MASTER TECH FROM HYUNDAI TO LOOK AT IT, BUT I WANTED TO DOCUMENT THIS ISSUE. I NOTICED IT FIRST WITHIN TWO WEEKS OF PURCHASE. HYUNDAI SUPPORT CLOSED MY CASE SEVERAL TIMES WITHOUT ACTION. I BOUGHT IT 5 MONTHS AGO. CURRENT MILEAGE IS 3462, SO IT IS WELL WITHIN WARRANTY.

MY BRAND NEW 2017 SANTA FE LIMITED HESITATES BADLY WHEN COMING OUT OF TURNS AT A SLOW SPEED AND ATTEMPTING TO ACCELERATE...JUST SHORT OF COMING TO A STOP. IT ALSO OCCURS WHEN VEHICLE IS AT A STOP THEN I STEP ON THE ACCELERATOR. IT IS A SAFETY ISSUE AS THE VEHICLE LAGS WHEN ATTEMPTING TO ENTER TRAFFIC OR THE VEHICLE COULD BE HIT FROM BEHIND WHEN ATTEMPTING TO ACCELERATE AND IT MOMENTARILY DOES NOT RESPOND. THIS OCCURS EACH TIME I DRIVE IT.

I NO LONGER OWN THE DESCRIBED VEHICLE BUT WANT TO REPORT A SAFETY ISSUE WITH THE VEHICLE. I HAD ADVISED HYUNDAI CONSUMER AFFAIRS ANALYST, CENTRAL/CA RAYNISHA M. AND WAS ASSIGNED A CASE NUMBER 10184122. INFORMATION ABOUT THE CASE NUMBER CAN BE OBTAINED FROM HYUNDAI. MY PROBLEM WITH THE VEHICLE WAS RELATED TO THE SPEED CONTROL SYSTEM OR "FLY BY WIRE" MECHANISM ON MY VEHICLE. ON SEVERAL PERSONALLY DOCUMENTED INSTANCES (WITH ROAD CONDITIONS, DATES, TIME SPEED ETC.) I EXPERIENCED A ZERO ACCELERATION RESPONSE FROM THE VEHICLE WHEN APPLYING ACCELERATOR PRESSURE. ON MANY ACCELERATION INCIDENTS THE ACCELERATION PEDAL RESPONSE "FELL ON ITS FACE" AND ON ONE OCCASION NEARLY RESULTED IN A VEHICLE COLLISION WHEN I WAS PROCEEDING INTO AN INTERSECTION. I HAD REPORTED THE SAFETY ISSUE TO BOTH MY HYUNDAI DEALERSHIP AND HYUNDAI CONSUMER AFFAIRS. THE TWO MECHANICAL INSPECTIONS THAT WERE PERFORMED TO IDENTIFY THE PROBLEM WERE INCOMPLETE AS THE VEHICLE DIDN'T THROW OFF ANY CODES TO IDENTIFY THE PROBLEM AREA. I WAS TOLD BY THE VEHICLE MECHANICS THAT SINCE THE PROBLEM WAS INTERMITTENT IN NATURE THAT I WOULD HAVE NO REDRESS ON THE SAFETY ISSUE. I AM A PRIVATE PILOT AND FLY AIRCRAFT UTILIZING "FLY BY WIRE" ACCELERATION DEVICES AND I CAN ASSURE YOU THAT MY FIRST INCIDENT OCCURRENCE WOULD HAVE GROUNDED THE AIRCRAFT EXPERIENCING THE SIMILAR ACCELERATION ISSUE. I AM REPORTING THIS TO YOU HOPING THAT YOU CAN INVESTIGATE AND OPEN A RECALL INQUIRY AND FORCE HYUNDAI TO FIX OR MAKE CHANGES TO VEHICLES THAT UTILIZE THEIR "FLY BY WIRE" ACCELERATION SYSTEMS.

TL* THE CONTACT OWNED A 2017 HYUNDAI SANTA FE. WHILE THE CONTACT'S HUSBAND WAS MAKING A LEFT TURN AT 10 MPH, THE VEHICLE FAILED TO GAIN SPEED WHILE THE ACCELERATOR PEDAL WAS DEPRESSED. ANOTHER VEHICLE TRAVELING FROM THE OPPOSITE DIRECTION STRUCK THE FRONT PASSENGER SIDE OF THE CONTACT'S VEHICLE. ALL OF THE AIR BAGS DEPLOYED. A POLICE REPORT WAS FILED AND THE DRIVER RECEIVED A CITATION FOR FAILING TO YIELD. THE DRIVER SUSTAINED A BROKEN LEFT WRIST, CUTS TO THE LEFT HAND, AND BRUISES TO THE UPPER BODY/TORSO. THE CONTACT (PASSENGER) SUSTAINED A BROKEN NECK THAT REQUIRED SURGERY DUE TO INTERNAL BLEEDING, SEVERE BRUISING FROM THE CHEST DOWN TO THE LOWER TORSO, AND BRUISING ON THE RIGHT AND LEFT ARMS. MEDICAL ATTENTION WAS RECEIVED. THE CONTACT HAD SURGERY TO HER RIGHT HIP TO REMOVE A BONE TO PLACE IN HER NECK. THE VEHICLE WAS TOWED TO A LOCAL DEALER (A1 WRECKER 1601 PARTIN DR N D, NICEVILLE, FLORIDA 32578). THREE WEEKS PRIOR TO THE CRASH, THE VEHICLE HESITATED TO ACCELERATE WHEN THE ACCELERATOR PEDAL WAS DEPRESSED. THE FAILURE OCCURRED WITHOUT WARNING. THE CONTACT STATED THAT THE VEHICLE GRADUALLY ACCELERATED INDEPENDENTLY. NEITHER THE MANUFACTURER NOR THE DEALER WERE MADE AWARE OF THE FAILURE. THE VEHICLE WAS DEEMED DESTROYED.

2017 SANTA FE ULTIMATE 2.0T. CAR DOES NOT ACCELERATE AND LAGS. HAPPENS AT A LOWER SPEED AND FROM A STOP. VERY SCARY WHEN MAKING A LEFT TURN AND ENTERING FREEWAY.DEPRESSING ACCELERATOR AND NOTHING HAPPENS FOR A SECOND OR MORE, THEN ALL OF A SUDDEN IT TAKES OFF. AT LOW SPEED IN PARKING LOT DEPRESS ACCELERATOR LIGHTLY AND CAR TAKES OFF. WHEN ACCELERATING FROM A STOP CAR WILL ACCELERATE QUICKLY WHILE DEPRESSING PEDAL GENTLY. DOES NOT HAPPEN EVERY TIME BUT IS FREQUENT ENOUGH TO BE CONCERNED. HAS HAPPENED SINCE NEW.

SOMETIMES, WHEN I PRESS THE GAS TO ACCELERATE, MY CAR DOES NOT GO. IT WILL MOVE FORWARD AT A SLOW PACE BUT THEN DOESN'T GO AS FAST AS I'M PRESSING THE GAS PEDAL, EVEN THOUGH MY RPMS ARE INCREASING. THIS HAS ALMOST CAUSED AN ACCIDENT BECAUSE THE CAR DOES NOT PERFORM AS IT SHOULD. HAPPENED TODAY FOR PROBABLY THE 10TH TIME SINCE I'VE HAD THE CAR, LESS THAN A MONTH. PULLING OUT OF A PARKING LOT ONTO THE STREET, MY CAR MOVE'S FORWARD VERY SLOWLY THEN WHEN I GO TO INCREASE MY SPEED THE CAR DOESN'T GO FASTER.

PULLED INTO PARKING SPACE IN A PARKING LOT VERY SLOWLY. VEHICLE WAS ALMOST PARKED.STEERING WHEEL WAS TURNED TO THE LEFT. VEHICLE SUDDENLY ACCELERATED, CONTINUED TO REV AND WOULD NOT STOP RIGHT AWAY WITH MULTIPLE APPLICATIONS OF THE BRAKE. IT RODE UP ONTO A CEMENT HANDICAP RAMP AND ITS RAILING AT THE HEAD OF THE SPACE .NOT INJURED, NO AIRBAG DEPLOYMENT, CAR SUSTAINED DAMAGE TO FRONT AND UNDERCARRIAGE. VEHICLE HAD LESS THAN 1200 MILES ON IT. NO ONE I TOLD WAS CONVINCED THAT I DIDN'T STEP ON THE GAS AND ASSUMED THAT MY FOOT MUST HAVE SLIPPED OFF THE BRAKE AND ONTO THE GAS PEDAL. I WAS READY TO BELIEVE IT MYSELF AND OWNED THAT IT MUST HAVE BEEN COMPLETELY MY FAULT. AFTER STUMBLING (AND I MEAN STUMBLING-WASN'T LOOKING FOR ANYTHING LIKE THIS) ACROSS REVIEWS AND COMMENTS THAT DESCRIBE EXACTLY WHAT HAPPENED TO ME, I FEEL VINDICATED. *TR

WHILE DRIVING OUR 2017 HYNDAI SANTA FE ON INTERSTATE 64 WITH THE CRUISE CONTROL SET AT 65 MPH THE TRANSMISSION WILL DOWN SHIFT TO 5TH AND THEN 4TH AND THEN 3RD GEAR WITH THE RPM ALMOST RED LINING. THIS IS WHILE GOING DOWN A SLIGHT DOWNGRADE. I'VE BEEN HAVING TO USE THE MANUAL MODE TO SHIFT BACK UP TO 6TH GEAR. WE CONTACTED THE LOCAL HYUNDAI DEALER WHO STATED THEY WERE AWARE OF THE PROBLEM BUT DID NOT HAVE A SOLUTION TO THE PROBLEM AT THIS TIME. I AM WORRIED ABOUT THE SAFETY OF THIS VEHICLE WITH THIS PROBLEM.

BRAND NEW VEHICLE (1600 MILES) HESITATES WHEN I GO FROM A COMPLETE STOP AND START TO ACCELERATE AT LOW SPEEDS. MAINLY NOTICE IT WHEN TAKING A CORNER. IT SEEMS AS IF IT HAS TROUBLE SELECTING THE GEAR AND ONCE IT DOES, IT LURCHES FORWARD. DANGEROUS WHEN PULLING OUT INTO TRAFFIC AS THE HESITATION PUTS YOU IN THE MIDDLE OF THE ROAD JUST A LITTLE TOO LONG FOR COMFORT. ALSO, MY TRACTION CONTROL LIGHT WILL COME ON AROUND CERTAIN CORNERS AND LEAVES ME WITHOUT CONTROL OF THE CAR. ALSO ANOTHER SAFETY ISSUE AS AGAIN THE CAR HESITATES OR LOCKS UP BECAUSE OF THIS FEATURE AND DOESN'T ALLOW ME TO DRIVE FORWARD AS I WISH. IT'S THE MIDDLE OF THE SUMMER WITHOUT ANY RAIN AND DEFINITELY NO SNOW ON THE GROUND (I'D SAY PERFECT ROAD CONDITIONS) SO NO REAL REASON WHY MY TRACTION CONTROL SHOULD BE TURNING ON AROUND CORNERS. VERY CONCERNED ABOUT THIS ISSUE! ALSO, I SHOULD NOTE THAT THESE ISSUES HAVE BEEN HAPPENING LONG BEFORE 1600 MILES. I NOTICED THEM THE FIRST WEEK OR SO THAT I TOOK THE VEHICLE HOME SO DEFINITELY LESS THAN 500 MILES AS I BOUGHT IT NEW. FOR A BRAND NEW, FAIRLY EXPENSIVE VEHICLE I SHOULDN'T HAVE TO FEEL LIKE MY CONFIDENCE IN IT'S BASIC PERFORMANCE IS COMPROMISED.

ON APRIL 15, OUR BRAND NEW SANTA FE WAS INVOLVED IN AN ACCIDENT. WHILE DRIVING IN LOW SPEED TRAFFIC SUDDENLY, WHILE MY FIANCE REAR ENDED SOMEONE. TO THIS DAY SHE CANNOT FIGURE OUT WHAT HAPPENED. SHE IS A CAREFUL DRIVER, DOES NOT SPEED AND KNOWS THAT THE AREA WERE SHE WAS DRIVING IS HIGH TRAFFIC AND WAS COMING UP TO A RED LIGHT. BOTH OF HER HANDS WERE ON THE WHEEL AND SHE WASN'T ON A PHONE OR ANYTHING. SHE BELIEVES SHE HIT THE BREAKS, AND AS STATED BEFORE STILL DOES NOT KNOW WHAT HAPPENED. AFTER READING THESE COMPLAINTS WE ARE WONDERING IF WE HAD THE SAME ISSUE AS SOMEONE ELSE WHO REPORTED AND IS THE CAUSE OF THE ACCIDENT. WE FIGURED WE WOULD REPORT THIS. WE ARE ALSO WONDERING IF OTHER PEOPLE ARE HAVING SIMILAR ACCIDENTS SINCE THERE HAS BEEN A MAJOR ISSUE GETTING PARTS TO REPAIR SAID CAR (CAR HAS NOW BEEN OFF THE ROAD FOR 11 WEEKS MOST PARTS REQUIRED FOR REPAIR HAVE BEEN EXTERNALLY BACKORDERED AND HYUNDAI HAS BEEN EXTREMELY UNHELPFUL TO HELP US GET OUR CAR REPAIRED). THE CONSUMER STATED THE VEHICLE LUNGED FORWARD, WHILE SLOWLY DEPRESSING THE BREAKS. THE MANUFACTURER WAS NOTIFIED. UPDATED 11/2/2017*JS

WHEN DEPRESSING THE ACCELERATOR AT SPEEDS LESS THAN ABOUT 10MPH, THE VEHICLE HAS A VERY SIGNIFICANT HESITATION - ABOUT 2 SECONDS WHEN THE VEHICLE IS COMPLETELY NON-RESPONSIVE. HAPPENS EVERY TIME AT LOW SPEED TURNS, AND IS DANGEROUS WITH VEHICLES BEHIND.

Mileage: 100

THE CAR APPEARS TO HESITATE UPON ACCELERATION FROM A LOW SPEED, MOST NOTICEABLY COMING OUT OF TURNS. THE HESITATION IS RANDOM AND JERKS THE CAR FORWARD AND BACK. I TOOK IN FOR SERVICE AND THEY SAY NO FIX IS AVAILABLE. DEALER SAID IT WAS NOT A SAFETY ISSUE BUT A SATISFACTION ISSUE. THAT IS A FALSE STATEMENT, AS IT IS INDEED A HUGE SAFETY ISSUE. OTHERS HAVE INDICATED A SIMILAR PROBLEM AS WELL IN THE SANTA FE ONLINE FORUMS (HTTP://WWW.SANTAFEFORUMS.COM/ACCELERATION-ISSUES-T10953.HTML?S=8588CA5231ADDA19BDA5C53064AE9CC8&T=10953)
