What 983 owners told NHTSA about the 2017 Hyundai Tucson Fuel Cell

MY 2017 HYUNDAI TUCSON HAS BEEN EXPERIENCING EXTREMELY DANGEROUS ACCELERATION ISSUES THAT I WOULD LIKE TO BRING TO THE ATTENTION OF THE NTSB. THE VEHICLE WILL EXPERIENCE LACK OF ACCELERATION WHEN MERGING ONTO HIGHWAYS AND/OR MAKING TURNS THAT REQUIRE ACCELERATION. THE VEHICLE HAS DONE THIS ON SEVERAL OCCASIONS WHERE I WAS UNABLE TO CONTROL THE VEHICLE WITH ONCOMING TRAFFIC. I HAVE ALSO BEEN VERY CLOSE TO BEING REAR-ENDED AND/OR T-BONED DUE TO THESE ACCELERATION ISSUES. THIS IS A VERY DANGEROUS CONDITION THAT IS HAZARDOUS TO NOT ONLY THE OWNER'S OF THESE VEHICLES, BUT ALSO TO OTHER INNOCENT DRIVERS IN THEIR PATH. APPARENTLY HYUNDAI AND KIA VEHICLES ARE KNOWN TO HAVE THIS ISSUE AND HAVE BEEN MENTIONED IN RECENT ONLINE FORUMS. I REACHED OUT TO HYUNDAI MOMENTS AGO TO ADDRESS THIS ISSUE WITH THEM AND I AM HOPING THEY WILL RESPOND TO ME WITH A FIX AND/OR SOLUTION TO THIS HAZARDOUS CONDITION. MY VEHICLE IS GOING TO THE DEALERSHIP AGAIN TOMORROW 4/23/18 FOR THIS SAME ISSUE. THE LAST TIME I TOOK THE VEHICLE IN FOR THIS ISSUE I WAS TOLD THERE WAS NOTHING WRONG WITH THE VEHICLE. IT JUST HAPPENED AGAIN THE OTHER DAY AND I WAS YET AGAIN PUT INTO A VERY "CLOSE CALL" SITUATION. I HAVE A YOUNG SON AND I DO NOT FEEL SAFE IN THIS VEHICLE WITH THIS CONDITION OCCURRING INTERMITTENTLY AND UNEXPECTEDLY ON THE ROADWAY. HOW MANY PEOPLE NEED TO BE HIT DUE TO THIS OBVIOUSLY KNOWN ISSUE WITH THESE VEHICLES? MY VEHICLE TENDS TO DO THIS MORE OFTEN WHEN MERGING ONTO A HIGHWAY WHERE MORE ACCELERATION IS REQUIRED; HOWEVER, I HAVE ALSO EXPERIENCED THIS PROBLEM WHEN SLOWLY ACCELERATING FROM BEING STATIONARY AT TRAFFIC LIGHTS, STOP SIGNS, ETC.

I HAVE OWNED THE TUCSON SINCE 1/25/17.THERE IS A LAG/SURGE ISSUE WHEN EXCELERATING. NOT ALL THE TIME, BUT SEEMS TO BE HAPPENING MORE LATELY. IN HINDSIGHT THIS SITUATION HAD HAPPENED BUT I THOUGHT IT WAS JUST GETTING USE TO THE NEW VEHICLE. WHEN I BROUGHT IT IN FOR SERVICE I MENTIONED IT ON A COUPLE OF OCCASIONS. I WAS TOLD IT WAS DUE TO THE DUAL CLUTCH AND THE VEHICLE WAS "OPERATING AS INTENDED". I FIND THAT HARD TO BELIEVE THAT WHEN YOU ARE SITTING AT A STOP LIGHT AND STEP ON THE GAS WHEN THE LIGHT CHANGES IT LAGS THEN SURGES INTO THE INTERSECTION. OR, STOPPED IN TRAFFIC AND WHEN IT IS TIME TO MOVE FORWARD, LAG AND SURGE ALMOST HITTING THE VEHICLE IN FRONT OF ME. AS WELL AS MERGING ONTO A HIGHWAY AND LAGGING AS TRAFFIC IS COMING AT YOU AT 65 MPH AND YOU ARE LAGGING AND HOPING NOT TO BE HIT. I FIND IT HARD TO BELIEVE THAT HYUNDAI WANTS THEIR VEHICLES TO BE RUNNING IN THIS MANNER. I HAVE BEEN IN TOUCH WITH HYUNDAI CUSTOMER CONNECT AND THEY SEND ME BACK TO THE DEALERSHIP. WHEN I FIRST GOT ON TO YOUR SITE THERE WASN'T AS MANY REPORTS AS THERE ARE TODAY. THIS IS A VERY DANGEROUS SITUATION AND I DON'T WANT TO BE A STATISTIC. I HAVE OWNED SEVERAL HYUNDAI'S OVER THE YEARS BUT NEVER THEIR SUV. I AM KEEPING A RECORD OR EVERY TIME THIS HAPPENS.

ANY TIME FROM A STOPPED POSITION OR JUST ACCELERATING WHILE MOVING; I GET LAG OR NO ACCELERATION AT ALL. I HAVE A TUCSON TURBO. MY HUSBAND TOOK THIS VEHICLE INTO BE LOOKED AT IN OCTOBER AND THE DEALERSHIP HOOKED IT UP TO A COMPUTER AND RESET SOMETHING TO HELP REGULATE THE ACCELERATION. LEARNING THE DRIVING IS WHAT HE WAS TOLD IT WAS DOING. IT HELPED FOR A FEW DAYS MAYBE A WEEK BUT THEN STARTED BACK TO HAVING ISSUES. MY HUSBAND TOOK IT IN LAST FRIDAY & WAS TOLD THAT THIS IS HOW IT'S SUPPOSED TO BE. THE GUY IN THE SERVICE DEPARTMENT WOULDN'T EVEN LOOK AT IT AND TOLD MY HUSBAND THAT HE HAS THIS CONVERSATION AT LEAST 2 OR 3 TIMES A WEEK. HE DIDN'T LOOK AT IT OR RECORD OUR CONCERN. THIS IS DANGEROUS. I'VE ALMOST BEEN IN AN ACCIDENT. I PURCHASED THIS VEHICLE FOR SAFETY AND THIS IS NOT SAFE!

AT VARIOUS TIMES DURING DRIVING THE CAR'S ENGINE WILL FEEL LIKE THERE'S NO POWER OR NO GAS AND WILL GO INTO A STALL. THIS HAS HAPPENED BOTH DURING ACCELERATING FROM A STOP GOING INTO TRAFFIC AND DURING DRIVING AND ACCELERATING. I HAVE INQUIRED AT THE DEALERSHIP(FUCILLO HYUNDAI) AND THE SERVICE DEPARTMENT SUGGESTED TO USE 93 OCTANE, THAT WAS ALMOST A YEAR NOW AND STILL HAPPENS SPORADICALLY. THIS IS A VERY UNSAFE CONDITION ESPECIALLY WHILE PULLING INTO TRAFFIC AND THE CAR GOES INTO A "STALL". RESEARCHING BLOGS THIS IS HAPPENING TO OTHER OWNERS AND IS NOT ISOLATED TO ME.

HYUNDAIS DUAL CLUTCH SYSTEM IN MY TUCSON IS VERY UNSAFE. I WAS NOT AWARE OF ISSUES UNTIL 2.5 MONTHS AFTER OBTAINING THE VEHICLE. FROM A DEAD ATOP AT TIMES IT WILL NOT ACCELERATE AND ONLY RUN UP RPMS. OTHER TIMES IN TRAFFIC IT WILL ALSO NOT ACCELERATE AND RUN UP RPMS. DOING A GOOGLE SEARCH THIS WAS A HUGE ISSUE IN 2016 MODELS BUT NO RECALL WAS EVER DONE FOR THE 2017 MODELS HAPPENS ABOUT 1 TO 3 TIMES PER WEEK. COULD LEAD TO SERIOUS INJURY ACCIDENT.

AT TIMES WHEN I STOP AND ACCELERATE THE CAR HESITATES TO MOVE THEN IT JUMPS AND GOES MAKING IT DANGEROUS .

CAR WILL NO LONGER ACCELERATE OVER 60MPH AND WHEN THE CAR IS IN DRIVE IT SOMETIMES WILL NOT ACCELERATE FOR A COUPLE OF SECONDS FROM A COMPLETE STOP

THE VEHICLE AT TIMES WHEN GOING FROM A STOP WILL OCCASIONALLY TOTALLY LOSE ALL PROPULSION FOR A SPLIT SECOND WHICH HAS CAUSED ME TO ALMOST BE DEAD IN TRAFFIC. IT IS VERY SCARY WHEN IT HAPPENS. I DON'T KNOW IF IT IS A ENGINE OR TRANSMISSION OR FUEL PROBLEM. I HAD THE PROBLEM WITH A 2014 SANTA FE. MY BROTHER IN LAW HAS THE SAME PROBLEM WITH THE SAME VEHICLE.

I HAVE AN ACCELERATION PROBLEMS, FROM THE TIME I PURCHASED THE VEHICLE. YOU DATE BELOW INDICATES ONLY 1 TIME. SO WHEN THE CAR IS STOPPED AND TRYING TO PULL OUT ONTO A HIGHWAY OR TRYING TO MAKE A TURN ACROSS A LANE OF TRAFFIC, THERE IS NO ACCELERATION, NO GAS, A HESITATION I CAN PUNCH THE GAS PEDAL TO THE FLOOR BEFORE IT ACTUALLY WILL MOVE THEN THERE'S A LURCH FORWARD. THIS IS A BIG CONCERN, I CAN NOT HAVE ANY TRAFFIC AT ALL ONCOMING IF I NEED TO MAKE A TURN. THIS HAPPENS PULLING ONTO THE INTERSTATE, ALSO FROM A STATIONARY OR ALMOST STATIONARY POSITION. I CAN'T HAVE ANY TRAFFIC COMING THERE'S SUCH A HESITATION. I'M AFRAID THIS WILL RESULT IN A COLLISION. THIS DOESN'T HAPPEN EVERY TIME, I'D SAY A 50/50 CHANCE OF IT HAPPENING. I HAVEN'T HAD AN ACCIDENT YET BECAUSE OF IT. VERY CONCERNED, AFRAID TO LET ANYONE DRIVE THE CAR AS I'M AWARE OF THE ISSUE AND AM VERY CAUTIOUS.

NHTSA ODI 11040419

CAR WILL NOT ACCELERATE WHEN GAS PEDAL IS DEPRESSED STANDING AT RED LIGHT. VERY DANGEROUS. I WAS ALMOST REAR ENDED.

NHTSA ODI 11040437

AFTER STOPPING THE VEHICLE DOES NOT RESPOND TO THE GAS PEDAL, SEVERE LAG. I HAVE ALMOST BEEN IN 3 ACCIDENTS IN 2 WEEKS, I AM ON BLOOD THINNERS SO THIS PRESENTS A LIFE THREATENING ISSUE FOR ME, I AM PURSUING ALL COMPLAINT OPTIONS AND LOOKING FOR A FULL REFUND. THE CAR IS ONLY 2.5 WEEKS OLD AND HAS LESS THAN 100 MILES ON IT. THE PROBLEM IS INTERMITTENT SO YOU CAN NEVER BE SURE WHEN IT IS GOING TO HAPPEN.

MY VEHICLE IS UNPREDICTABLE WHEN SHIFTING OR ACCELERATING. I HAVE HAD IT LOOSE ALL POWER WHEN TRYING TO ACCELERATE WHEN PULLING INTO TRAFFIC. ALSO IT SEEMS TO GO INTO A NEUTRAL STATE SOMETIMES OR DOES NOT SHIFT PROPERLY AND RUNS THE RPMS HIGH AND SHIFTS UP AND DOWN BEFORE CATCHING THE RIGHT GEAR. I HAVE ALREADY HAD AND UPDATE AT THE DEALERSHIP AND WAS TOLD THAT THERE WOULD MOST LIKELY BE MORE AND THAT IT'S LIKE HAVING A MANUAL TRANSMISSION THAT GOES INTO NEUTRAL BY ITSELF AND TO JUST BE AWARE THIS COULD HAPPEN. NOT COMFORTING TO ME. I HAVE ALSO HAD PROBLEM WITH ANY ACCELERATION WHEN IN REVERSE BEING SLUGGISH OR NOT MOVING A COUPLE OF TIME.

WE JUST PURCHASED A 2017 HYUNDAI TUCSON SPORT. THE CAR HAS A SERIOUS ISSUE OF NO ACCELERATION AFTER A STOP, MERGING, PASSING ON THE HIGHWAY AND TURNING AT AN INTERSECTION. THE CAR HESITATES WHEN YOU HIT THE ACCELERATOR, SOMETIMES LEAVING YOU NEARLY STOPPED IN A AN INTERSECTION WAITING FOR A CAR TO HIT YOU. IF YOU CHOOSE TO CHANGE LANES ON A HIGHWAY THE CAR WILL HESITATE WHEN YOU PRESS THE ACCELERATOR TO MAKE THE LANE CHANGE. MY WIFE HAS STOPPED DRIVING THE CAR DUE TO THE SERIOUSNESS OF NO ACCELERATION AND SAFETY CONCERNS. WE HAVE TAKEN THE CAR BACK TO THE DEALERSHIP AND THEY SAID THE DIAGNOSTICS SHOW THAT THE CAR IS FINE AND IT IS HOW THE HYUNDAI TRANSMISSION WORKS IN THESE VEHICLES. I THINK THE CAR COULD BE A "LEMON." NOT SURE WHAT TO DO.
