What 1,536 owners told NHTSA about the 2016 Hyundai Tucson Fuel Cell

05/06/2016 @ 1600 COND-RAINY. WHILE AT A STOP LIGHT I PRESSED THE ACCELERATOR AND THE SUV DID NOT MOVE. THE ENGINE REVVED BUT THE SUV DID NOT GO FORWARD. IT SLOWLY ENGAGED AND LURCHED FORWARD AFTER APPROX 3-5 SECONDS. 5/19/2016 @ 1800 COND-RAIN /NOT DRIVEN IN APPROX 4 DAYS. LESS THAN A MILE FROM START AND HAD BEEN DRIVING FOR APPROX 3-5 MINS-WHILE WAITING AT A STOP LIGHT I ATTEMPTED TO ACCELERATE WHEN THE LIGHT CHANGED AND THE VEH DID NOT MOVE. I PRESSED THE ACCELERATOR TO THE FLOORBOARD AND THE ENGINE REVVED FOR APPROXIMATELY 5-7 SECONDS BEFORE THE VEH LURCHED/JUMPED FORWARD AND SLOWLY MOVED. I AGAIN IMMEDIATELY WENT TO HYUNDAI. I WAS GIVEN A LOANER VEHICLE - 2016 TUCSON. 5/21/2016 @ 1350 SAME NON-MOVEMENT WHILE ACCELERATING FROM A STOP OCCURRED W/THE LOANER VEHICLE. IT HAD NOT BEEN DRIVEN IN 2 DAYS COND-RAINY. THIS OCCURRED APPROX 3 MINS AFTER START AND W/IN A MILE. HYUNDAI CORP ARE NOT TAKING RESPONSIBILITY FOR THE ISSUES WITH THIS VEH. 3 SIMILAR ISSUES FROM CUSTOMERS WERE REPORTED TO THIS DEALERSHIP. I DO NOT FEEL SAFE DRIVING THIS VEH OR ALLOWING ANY MEMBER OF MY FAMILY TO DRIVE THIS VEH. IT IS AN ACCIDENT IN WAITING EITHER FROM BEING HIT FROM BEHIND BY ANOTHER VEH OR FROM STRIKING ANOTHER B/C OF THE LURCHING. I HAD TO PUT MY HAZARDS ON AND HOPE THAT I DID NOT GET HIT FROM BEHIND. I AM NOT SATISFIED AND WANT A REFUND FOR BOTH OF THE VEH'S I PURCHASED DUE TO THIS HUGE SAFETY ISSUE. AT RANDOM TIMES, USUALLY FROM A STOP, BUT SOMETIMES WHEN PULLING INTO TRAFFIC, THE VEH DOES NOT MOVE. I CONSIDER THIS TO BE A VERY HAZARDOUS DEFECT. HYUNDAI IS UNABLE TO REPLICATE THE ERROR, SO ENG. ADVISES TO RELEASE THE VEH BACK TO ME, THEY ARE UNAWARE OF ANY SIMILAR PROBLEMS. I WILL NEVER DRIVE ANOTHER HYUNDAI VEH AGAIN B/C IT IS UNSAFE AND THE LACK OF RESPONSIBILITY TO RECTIFY THEIR MANUFACTURING PROBLEM. IT IS NOT A DRIVER'S OPERATIONAL ERROR.

REPORTED HESITATION WHEN TRYING TO ACCELERATE FROM A STOP, IN TRAFFIC, OR WHEN EXITING A TURN. SERVICE TECH ACKNOWLEDGED AS DID THE SALES TEAM THAT THEY EXPERIENCED THE ISSUE IN THE VEHICLE BUT SINCE THERE ARE NO RECALLS THAT APPLY TO THE VEHICLE THERE IS NOTHING THEY CAN DO UNTIL CORPORATE DECIDES TO ADDRESS THE ISSUE. HAVE HAD SEVERAL TIMES WHEN THE VEHICLE WOULD NOT ACCELERATE WHEN TRYING TO MERGE WITH TRAFFIC AND HESITATES OR LUNGES WHEN COMING TO A STOP SOME TIMES. CONTINUES TO HAPPEN WHEN DRIVING SINCE FIRST PURCHASED ON 5/21/2016.

THE CAR OCCASIONALLY EXHIBITS THE FOLLOWING BEHAVIOR: 1.UPON ACCELERATION FROM A STOP, THE TRANSMISSION SEEMS TO BE IN A GEAR HIGHER THAN FIRST, WHICH THEN CAUSES THE MOTOR TO STALL AND LOSE POWER FOR ONE TO THREE SECONDS BEFORE RESUMING ACCELERATION. THE LOSS OF POWER PUTS THE CAR IN PERIL OF BEING REAR ENDED BY VEHICLES FOLLOWING BEHIND. 2.WHEN IN THIS STATE, MOVING THE GEARSHIFT LEVER LEFT TO ENTER MANUAL MODE FAILS ' THE TRANSMISSION STAYS IN DRIVE DESPITE SEVERAL ATTEMPTS TO ENGAGE MANUAL MODE. 3.BECAUSE THE TRANSMISSION NEVER DOWNSHIFTS TO LOWER GEARS, THE CAR RUNS ROUGH AT SLOWER SPEEDS. 4.TURNING THE CAR OFF AND BACK ON AGAIN RESTORES IT TO NORMAL OPERATION UNTIL THE ERRANT BEHAVIOR HAPPENS AGAIN ON RANDOM, UNPREDICTABLE OCCASIONS. THIS CAR IS EQUIPPED WITH A TURBO-CHARGER. A FACTORY RECALL TO FIX AN ACCELERATOR HESITATION IMPROVED, BUT DID NOT ELIMINATE, SAID HESITATION.
