What 370 owners told NHTSA about the 2019 Hyundai Tucson Fuel Cell

I’m traveling for work and I have only had to car 11 months. I have 52,000 miles on it and today tracking home my car engine light came on and my car wouldn’t shift through the hills in Missouri. It got so bad after 1 mile of the engine light flashing at me that I had to stop in a construction highway with one lane and stop all traffic to let my car cool down for almost 15 minutes and I started it up and it would not go over 10 miles a hour. With my flashers on I got off the next exit and ran a diagnostic at O’riley’s in St. James Missouri. My codes are reading CAMSHAFT IGNITION CONTROL (P000B) and IGNITION CONTROL MODULE COMBUSTION QUALITY INPUT SIGNAL (P1326)

The contact owns a 2019 Hyundai Tucson. The contact stated while in her daughter's possession, the engine had failed to start after multiple attempts. Several warning lights illuminated the instrument panel during the failure. The vehicle was jumpstarted and the horn began to blare once the engine restarted. The vehicle was taken to a dealer where they were unable to determine the failure. The contact also stated that the vehicle would rattle while both idle and upon activation of the AC. The manufacturer was notified of the failure and the contact was given to a case manager; she was later instructed by the case manager to take the vehicle back to the dealer for assistance. The vehicle had yet to be repaired. The failure mileage was approximately 23,000.

While driving down a busy road at 10:00 pm on New Years Eve, my vehicle's engine completely shut off. Immediately prior to the shut off, the vehicle's dash displayed the oil and battery lights. The vehicle's automatic emergency brake and steering wheel lock were both engaged, not allowing me (or the tow truck company) to move my vehicle out of this busy road. My car remained in this location for 3 and a half hours. The hazard lights stopped working after the first hour, making it extremely difficult to see that the vehicle was stopped. After the second hour, an officer parked behind my vehicle with their lights flashing as he said it was an extremely dangerous situation and my car was sure to be hit. He was able to get a tow truck to me before Hyundai. For hours, numerous people were forced to brake quickly/swerve into other lane to avoid hitting my car. This occurred right before an intersection, putting 4 directions of drivers at risk of collision. I stood in the rain, near my car, attempting to help direct drivers away from the lane until the police officer showed up. The vehicle is now at the dealership which confirmed engine failure, pending replacement. Possibly related, this vehicle had the catalytic convertor replaced 3 months prior. It is not yet confirmed if this contributed to the engine failure.

Purchased the vehicle in June 2021 only had 1 previous owner. The dealership stated it was a pre-owned certified used vehicle that had just been inspected and service. Within the first month I had to take it back for multiple issues most recently the catalytic converter to be replaced and the Engine. I haven't even owned it let alone driven it long or far enough for either of these parts to need service or have failed. It's not even time for my first oil change that how low the mileage is that I've put on it. The dealership originally told me they never head about the complaints regarding the engine now they are trying to stiff me on selling me a lemon by charging me 3000 and telling me Hyundai isn't willing to cover the repairs. If this is a known issue which is seems to be a recall should now be issued.

Going up a hill, "Check Blind-Spot Collision Warning System" alert, clunk sound, rpms revved high, power lost and did not shift gears. 2 occurrences. Approximately 40,000 miles.

MY VEHICLE HAS ISSUES W/ACCELERATION - IT IS SLOW, HESITATES, AND FAILS TO MAINTAIN SPEED AT TIMES. FURTHER, THE TRANSMISSION CAUSES FREQUENT RPM SURGES, REGARDLESS OF SPEED OR TERRAIN OR ROAD TYPE (IT IS MOST FREQUENT WHEN GOING UP A HILL, BUT ALSO HAPPENS ON A FLAT ROAD). I WAS COMING TO A STOP AND WHILE SLOWING DOWN, WITH THE BRAKES APPLIED, THE ENGINE REVVED TWICE. AFTER READING OTHER COMPLAINTS, THEY ALL SEEM TO BE ABOUT THE SAME THINGS AND NEED FIXED. I HAVE A SON THAT WILL START DRIVING IN THE FALL AND I'D LIKE TO BE ABLE TO RELY ON THE CAR TO RUN CORRECTLY AND WITHOUT ISSUES. THIS IS A MANUFACTURING ISSUE AND NEEDS FIXED - IT'S A SAFETY ISSUE FIRST AND FOREMOST. *TR

THE TRANSMISSION ISN'T SHIFTING OUT PROPERLY. YOU CAN HEAR THE CAR REVVING UP AND NOT CHANGING GEARS. THE ACCELERATION IS SLOW AS WELL. ALTHOUGH I'M PRESSING ON THE GAS, IT TAKES A WHILE FOR THE CAR TO PICK UP SPEED. THE DRIVER SEAT IN MY BRAND NEW TUSCAN IS ALSO PEELING. I HAVEN'T CLEANED THE SEAT WITH ANY KIND OF CHEMICALS, BUT A SMALL SPOT IS VISIBLY PEELING.

MY VEHICLE IS EQUIPPED WITH A DCT, WHICH CAUSES THE VEHICLE TO SLOW, HESITATE, FAIL TO MAINTAIN SPEED, AND STOP WITHOUT WARNING. FURTHER, THE TRANSMISSION CAUSES FREQUENT RPM SURGES, REGARDLESS OF SPEED OR TERRAIN OR ROAD TYPE (IT IS MOST FREQUENT WHEN GOING UP A HILL, BUT ALSO HAPPENS ON A FLAT ROAD). WHEN MERGING ONTO A HIGHWAY ON A HILL, I MUST USE THE SLOW VEHICLE LANE TO GET UP TO SPEED BEFORE MERGING INTO TRAFFIC. OFTEN, I WILL PULL OUT TO PASS A CAR AND THE TRANSMISSION WILL FAIL TO RESPOND, CAUSING ME TO SLOW RAPIDLY. I HAVE TAKEN THIS TO THE DEALERSHIP ON MULTIPLE DATES DURING THE YEAR I'VE OWNED AND HAVE BEEN REPEATEDLY TOLD THAT IT IS "NORMAL" AND THAT IT WILL "LEARN MY DRIVING HABITS. THE LATTER IS UNTRUE, IT DOES NOT LEARN AND I NEED TO ADAPT MY DRIVING HABITS TO THE UNCERTAINTY OF THE TRANSMISSION. THIS IS UNSAFE AND PUTS ME AND OTHER DRIVERS AT RISK. ON MULTIPLE OCCASIONS THE VEHICLES BEHING ME, REGARDLESS OF FOLLOWING DISTANCE, HAVE HAD TO SWERVE OR BRAKE DUE TO MY VEHICLES FAILINGS.

I BOUGHT THIS 2019 HYUNDAI TUCSON SPORT NEW IN MAY OF 2019. I NOW HAVE 9,000 MILES ON IT. THE VEHICLE SUFFERS FROM CONSTANT HESITATION ISSUES WHEN ACCELERATING. THIS OCCURS FROM A DEAD STOP, WHILE TURNING, AND WHILE TRYING TO QUICKLY SPEED UP TO AVOID A CRASH. IT IS LIKE THE FUEL HAS BEEN MOMENTARILY SHUT OFF. THIS IS EXTREMELY UNSAFE. WE HAVE AVOIDED SEVERAL NEAR-CRASHES THROUGH SHEER LUCK IN THE PAST COUPLE OF MONTHS. THIS IS THE 2.4 ENGINE AND 6 SPEED AUTO/SHIFT ABLE TRANSMISSION. IF I PUT THE MODE TO SPORT, IT HELPS SOME. TO AVOID THE DANGEROUS LAG OF APPROXIMATELY 2 SECONDS, THE CAR HAS TO BE DRIVEN IN MANUAL MODE. WHEN THE CAR IS STANDING STILL AT THE LIGHT, EVERYTHING APPEARS NORMAL. BUT AS THE LIGHT CHANGES AND I ACCELERATE, IT WILL SUDDENLY "STALL" FOR ABOUT TWO SECONDS, THEN IT WILL SPEED UP. IT IS LIKE THE ENGINE IS HAVING TROUBLE COMMUNICATING WITH THE TRANSMISSION. I HAVE CALLED SEVERAL DEALERS AND THEY SAY THERE IS NO FIX. NUMEROUS OTHER OWNERS OF THESE VEHICLES ARE MAKING THE SAME COMPLAINT. I DO NOT WANT A NEW VEHICLE. I ALREADY HAVE ONE. I JUST WANT IT FIXED BEFORE SOMEONE GETS KILLED. PLEASE REVIEW ALL THE CONSUMERS COMPLAINTS ON THIS HYUNDAI TUCSON. I ALSO RENTED A VEHICLE FOR A DAY AND IT WAS A 2018 HYUNDAI TUCSON. IT DID THE EXACT SAME THING. THIS IS EXTREMELY DANGEROUS. THANK YOU.

2019 HYUNDAI TUCSON LIMITED. SPORADIC HESITATION ACCELERATION FROM STARTING FROM A COMPLETE STOP. I'VE HAD THE CAR SINCE JUNE AND HAVE LESS THAN 3500 MILES ON IT. WHEN YOU START FROM A RED LIGHT THE CAR WILL JERK AND HESITATE, ALMOST LIKE IT'S OUT OF GAS BUT THEN IN THE MIDDLE OF THE INTERSECTION IT WILL ACCELERATE LIKE NORMAL. THIS HAS ONLY HAPPENED TO ME WHILE IN NORMAL DRIVING MODE. IT HASN'T DONE THIS WHILE IN SPORT OR MANUAL SHIFTING MODE. I HAD TO SELECT A DATE OF WHEN THIS HAPPENED BUT IT ORIGINALLY STARTED AROUND MID JULY AND SPORADICALLY TO THIS DAY. IT HAPPENS RANDOMLY BUT WHEN IT DOES IT HAPPENS AT CONSECUTIVE STOP LIGHTS AND MULTIPLE TIMES ON THE SAME DAY. THIS ISN'T A DCT, SO HYUNDAI, NOR THE DEALER CAN SAY I'M DRIVING THE CAR INCORRECTLY. PRETTY DISAPPOINTING TO HAVE MY FIRST EVER BRAND NEW CAR HAVE A SERIOUS ISSUE LIKE THIS.

SPORADIC HESITATION WHEN STARTING FROM A COMPLETE STOP. THIS HAS HAPPENED TO ME ABOUT 15 TIMES, USUALLY WHEN PULLING OUT INTO TRAFFIC. THE CAR HAS 4000 MILES AND HAS BEEN IN SERVICE ABOUT 6 MONTHS. THE SERVICE MANAGER.STATED THEY HAVE NO OTHER COMPLAINTS BUT IS PROBABLY DUE TO THE "SMART" TRANSMISSION ADAPTING TO DIFFERENT DRIVERS. I UNDERSTAND THAT THERE WAS A RECALL FOR 41,000 2017 TUSCONS FOR THE SAME ISSUE.
