What 383 owners told NHTSA about the 2018 Hyundai Tucson Fuel Cell

THE CAR STARTED MAKING A LOUD NOISE MY OIL LAMP LIGHT STARTED FLASHING, AFTER I STOPPED AT A RED LIGHT I ACCELERATED THEN MY ALTERNATOR LIGHT CAME ON THE CAR DIED. WITHIN SECONDS MY CAR STARTED SMOKING A WHITE COLOR LIGHTLY AND THEN WITHIN MINUTES THE SMOKE TURNED BLACK AND HEAVY THEN CAR CAUGHT ON FIRE.

MY CAR HAS 20,000 MILES ON IT. 2 MONTHS AGO AROUND 18,000 MILES MY CAR STARTED TO HESITATE DURING ACCELERATION. IT STARTED AS ONLY SOMETIMES. NOW IT HAPPENS EVERY TIME I DRIVE IT . WHEN IT IS STOPPED AND I PUSH ON THE GAS TO GO IT HESITATES. THE RPMS SHOOT UP TO 5-6 THEN IT GOES. THIS IS DANGEROUS ESPECIALLY IF YOU ARE CROSSING SEVERAL LANES OF TRAFFIC. ALSO WHEN IN MOTION AND YOU NEED TO ACCELERATE IT WILL HESITATE AS WELL. I BROUGHT IT TO THE DEALERSHIP AS IT'S UNDER WARRANT AND WAS TOLD IT'S THE DCT AND MANY PEOPLE HAVE COMPLAINED. AND IT'S NORMAL. I DISAGREE BECAUSE IF IT WAS NORMAL THEN IT WOULD HAVE DONE THIS WHEN I FIRST PURCHASED THE CAR.

HYUNDAI 2018 HAD A OIL LEAK ISSUE DUE TO A FAULTY OIL PAN. THE OIL PAN WAS SEALED BY THE DEALERSHIP. THIS DID NOT SEEM TO FIX THE ISSUE CAUSING THE OIL TO DRAIN ON THE FREEWAY AND SEIZE THE ENGINE. I WAS COASTING ON THE FREEWAY WITH NO POWER FROM THE ENGINE. WE WERE SCARED FOR OUR DEAR LIVES.

AT TIMES, WHILE DRIVING WITH THE TRANSMISSION IN DRIVE, THE VEHICLE HESITATES TO ACCELERATE AFTER BEING STOPPED, AS AT A RED TRAFFIC SIGNAL. WHEN THIS HAPPENS, PRESSING THE ACCELERATOR PEDAL TO THE FLOOR WILL START THE VEHICLE MOVING FORWARD 'VERY' SLOWLY FOR ABOUT 3 SECONDS, THEN IT WILL TAKE OFF WITH FULL POWER UNTIL ACCELERATOR PEDAL IS LET OFF. WHEN THIS HESITATION OCCURS, THE ENGINE DOES NOT SOUND OR FEEL LIKE IT IS STRAINING, OR MISFIRING AT ALL, IT SEEMS MORE LIKE THE COMPUTER IS NOT SENDING THE ENGINE THE SIGNAL TO REV UP AND GO, HENCE HAVING TO FLOOR IT TO GET IT TO MOVE. THIS CONDITION IS EXTREMELY DANGEROUS, TO THE POINT I AVOID HAVING TO MAKE LEFT TURNS AT TRAFFIC LIGHT INTERSECTIONS, BECAUSE I NEVER KNOW WHEN THE VEHICLE IS GOING TO EXHIBIT THIS BEHAVIOR, BUT THIS CAN HAPPEN WHETHER GOING STRAIGHT, OR MAKING A RIGHT-HAND TURN. THIS VEHICLE ONLY HAS 1,253 MILES AT PRESENT, BUT THIS CONDITION HAS BEEN HAPPENING SINCE IT WAS DRIVEN OFF THE LOT NEW.

AFTER ACQUIRING A LITTLE OVER A MONTH (1167 MILES ON IT) THIS CAR FAILED WHILE I WAS DRIVING ON A MAJOR HIGHWAY AND HAD TO NAVIGATE OVER 4 LANES FROM JUST MOMENTUM - COULD NOT USE MY CELLPHONE AS IT WAS TRYING TO SYNC TO THE CAR WHICH WAS NOW COMPLETELY DEAD. TOWED TO PURCHASING DEALER AND WAS DIAGNOSED AS BAD GROUND WIRE. I AM TERRIFIED TO DRIVE THIS CAR AGAIN, MY PASSENGER AND I COULD HAVE BEEN INJURED OR WORSE.

THE VEHICLE SHUT OFF WHILE DRIVING ON THE HIGHWAY AND WOULD NOT START BACK UP.

DELAYED ACCELERATION FROM STOP. VERY UNSAFE WHEN MAKING A LEFT HAND TURN AS IT WILL TAKE UP TO 10 SECONDS FOR THE CAR TO ACCELERATE. THIS HAPPENS OFTEN BUT NOT ALWAYS. I DO NOT FEEL SAFE DRIVING THIS CAR.
