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

Car has no power when accelerating, when accelerating from a stop the car revs but does not move, then when it does move it takes off like a rocket, in slow moving traffic 5 mph, you accelerate and the car seems like it wants to stall, a lot of hesitation, In fast moving traffic, if you want to merge or pass another vehicle you must give yourself ample time and make sure it is clear to make your move, if you need to get out of the way really fast you cant, its very dangerous and Hyundai needs to move quick on this before something really bad happens to someone.

my 2018 Hyundai Tucson starting having lurching issues on when first started. i have to back into my driveway so i dont have to go in reverse then go forward. it jerks back and forth so hard. It finally took its toll on the transfer case and it exploded internally. the Dealership said they had never seen this before. i was hoping that was the cause of the issue but it wasnt. Still doing it and am afraid it will do it again. i was under warranty when it happened, so teh $2000 replair was covered. i'm concerned it will happen again. teh problem goes away after it's been completely warmed up. but like many others, its a scary issue when first started. it also will also shift hard when it firsts get's going (after the initial hard lurching back and forth). i dont know what to do. Love the car otherwise, but concerned with ever buying a Hyundai again.

very bad acceleration from a stop position, engine revs but does not move, in slow traffic it hesitates and lunges forward like it’s not sure what it’s suppose to do, when trying to merge or pass another car, you have to give yourself time, it’s very dangerous, took it to the dealer 2 times, was told that’s how the car is made, there is no way this is suppose to be the way the car was built. also a smell of antifreeze but no leaks detected,

When merging into traffic, the car lost all acceleration and the transmission revved to a very high rpm. This has been an ongoing problem since the car was purchased. The dealer keeps saying they “cannot replicate”. This car is going to kill me.

Rod bearing failure. Sounded like a tractor all of a sudden and stalled every time I’d come to a stop. Had it towed to the dealership. Awaiting word from Hyundai as to whether the warranty will cover this. Checked oil and wasn’t low. No check engine lights or oil lights or anything ever came on. No noises prior to this happening. Kept up on routine maintenance.

The vehicle almost stalls and doesn't want to take off 1st thing in the morning then suddenly it accelerates abruptly well above the amount of pedal pushed. It also has inconsistent shifts at anytime during a drive. Sometimes it won't shift until we leave off the gas. This has been twice in for diagnosis at Rom Marhofer in Cuyahoga Falls, Ohio 44221. Both times they tell us--they could not get the vehicle to produce the symptoms. It does this everyday of the week for us--everyday. The service writer says this is common for the dual clutch transmission. This is a safety issue with not having power to move then suddenly--wham.

About 6 months of owning this vehicle, I started noticing while sitting in traffic that when letting off of the brake the car would start to jerk as you gave it a little throttle. I took the car to the Hyundai in Glendora where I purchased the vehicle from and they stated that there was nothing wrong with it. The issue continues to this day and I have voiced the complaint each time I bring the Vehicle in for maintenance. One of the service techs said that they felt the hesitation with the transmission but said that it was not bad enough to fix per Hyundai policy. This car is equipped with the Dual Clutch Transmisson because of the turbo. I have been dealing with this problem now for about 2 1/2 years and I feel that it is a safety issue being that the jerkiness and the hesitation could cause a crash. I actually talked to someone at another dealership and he told me that there was a Class Action Suit for this problem and to go that route. I just want Hyundai to own up to the problem and fix the issue.

Hyundai has historically had an issue with the dual-clutch transmission and the vehicle is available for inspection upon request. The vehicle frequently shutters / shakes at a stop and when accelerating from a stop. Additionally, the vehicle occasionally loses power to the wheels when driving-up a moderately steep grade. Additionally, the vehicle has delayed acceleration when trying to increase speed from a constant speed. This has put my safety and the safety of others at risk by being unable to properly accelerate into a turn while driving at highway speed, by being unable to keep up with the speed of traffic while driving on the interstate in the mountains, by being unable to drive in adverse weather, and by not being able to account for the jolting of the vehicle in busy city traffic. I've taken it to two manufacturer dealerships who have ran a shutter test and could not generate an error message, but acknowledged the effects felt when driving the vehicle and the commonality of the problem. They said their hands are tied if the manufacturer's testing generates a pass result. There have not been any warning lamps or messages. To date, I have been unable to come to a resolution, but the vehicle is dangerous to drive.

My 2018 Hyundai Tuscon has been having major issues with the dual clutch transmission, which has put myself, my family, and others in very dangerous situations. Everyday when I start my Tuscon and accelerate, it stutters/jerks like it’s going to stall and will not accelerate/shift. It eventually starts going, but I have to pull out onto a street, which has been unsafe when cars are speeding up behind me. It does not go up hills well at all. I turned onto a road where there was a decent sized hill, but nothing major, and nothing an SUV should have a problem with. My previous CAR could drive it just fine. You’d think an SUV could as well. Nope. Very scary moment. My Tuscon made it not even half way, and just stopped. I was pressing the gas, and it just revved it up with no motion. I braked and tried it again, and it still would not go. I had to roll backwards down the hill. This was the only way to my destination. I rolled down, and put it in sport mode to try that. It still would not go, and did the same thing. I tried again in regular mode, and it still would not go, only this time I had a car behind me. The car had to back down, and I rolled back a little bit, then hit the gas in drive and it eventually made it, but definitely very scary and unsafe, and it put others in danger as well. I was going to church one morning, and the speed limit on the main road is 60, which is what I was driving. I had to slow down to turn, and had to stop to oncoming traffic. I had to brake for maybe 10 seconds, and when I went to accelerate, it was like it wasn’t shifting, and it just revved up, rolled slightly, and would not go. At this point there are more cars coming. I am in the road right In their path due to it rolling, and once again I am put in a very scary situation. I kept trying, and it FINALLY went. This was also on flat level ground. I have had many moments (every day) where it does not shift properly, and it also stutters every single day when I start it. Please fix this

CAR WAS SLOWLY ENTERING GARAGE AND CAME TO A FULL STOP WITH BRAKE PEDAL DEPRESSED IN GEAR. CAR WITHOUT WARNING, ENGINE REVVED UP TO FULL POWER AND CRASHED IN GARAGE. I AM ALLEGING CONDITION KNOWN AS SUDDEN UNINTENDED ACCELERATION. I HAVE HAD THE DAMAGE REPAIRED AND THE COST OF REPAIR WAS OVER $4,000.00. PICTURES AVAILABLE UPON REQUEST. HYUNDAI PERFORMED AN INSPECTION ON VEHICLE UPON MY DEMAND TO DO SO. WHEN REPORT CAME IN, I WAS REFUSED A COPY OF EXACT REPORT BY INSPECTOR AND ONLY GIVEN A SUMMARY BY COMPANY AGENT. WHEN I ASKED FOR THE EXACT INSPECTOR REPORT TO BE READ TO ME OVER THE PHONE, THAT REQUEST WAS DENIED AS WELL.

CAR CONSTANTLY HESITATES WHEN STARTING TO ACCELERATE. WHEN YOU BEGIN TO ACCELERATE FROM A STOP, THE CAR HESITATES FOR SEVERAL SECONDS BEFORE BEGINNING TO MOVE. THIS IS VERY DANGEROUS WHEN MAKING TURNS AT STOP LIGHTS OR IN INTERSECTIONS. GOING AT HIGHWAY SPEED THE CAR RUNS FINE AND ACCELERATES WITHOUT ISSUE. THE PROBLEM IS WHEN AT SLOW SPEEDS OR AT A STOP AND YOU NEED TO ACCELERATE. ALSO, WHEN GOING SLOW OR SLOWING DOWN TO A STOP, THE CAR SEES LIKE IT IS GOING TO STALL AND THE ENGINE/TRANSMISSION BEGINS TO JERK AS IF IT IS ABOUT TO STALL. WHEN DRIVING THROUGH A PARKING LOT AT SLOW SPEEDS WITH SOME QUICK ON/OFF BREAKING, THE CAR HESITATES AND FEELS LIKE IT IS GOING TO STALL.

THE TRANSMISSION SEVERELY LAGS IN THE INITIAL TRANSITION INTO FIRST GEAR, AS WELL AS FROM FIRST TO SECOND. WHEN INITIALLY ENGAGING INTO FIRST GEAR FROM REVERSE, THE CAR RUMBLES AND CHOPS INTO FIRST GEAR. ALTHOUGH THIS IS A DUAL CLUTCH CAR, IT SEVERELY LAGS INTO ACCELERATION, CAUSING A MAJOR SAFETY HAZARD, ESPECIALLY ON THE FREEWAY. WE HAVE TAKEN THE CAR TO THE DEALER FOR REPAIRS BUT THEY HIDE BEHIND THE EXCUSE THAT THIS IS A DUAL CLUTCH TRANSMISSION. THE ISSUE FIRST OCCURRED AT AROUND 500 MILES. IT HAS ONLY GOTTEN WORSE SINCE.

WHEN THE VEHICLE IS AT A COMPLETE STOP IT WILL HAVE ISSUES GOING WHEN I PUSH ON THE GAS. IT TAKES A FEW SECONDS TO GO AND IT WILL JERK FORWARD AND THEN GO. IT DOESN'T HAPPEN EVERY TIME BUT IT IS OFTEN ENOUGH THAT IT'S WORRY SOME AND COULD BE UNSAFE.

HAS DEVELOPED INTTERMINTANT SHIFT STUTTER WHILE DRIVING (CITY AND HIGHTWAY) AND DEALYED POWER FROM A STOP (NO GO SYNDROME). THE PROBLEM ISGETTING WORSE AND THE HYUNDAI HASN'T BEEN ABLE TO FIX IT.

VEHICLE CAUGHT FIRE WHILE DRIVING ON THE HIGHWAY.

NHTSA ODI 11351329

BOUGHT THE VEHICLE NEW. THE PROBLEM ORIGINALLY BEGAN AS INTERMITTENT NOW OCCURRING ALMOST CONSTANTLY. IF VEHICLE IS IN A STOPPED POSITION UPON PRESSING THE ACCELERATOR THE VEHICLE DOES NOT MOVE FORWARD FOR UP TO ONE TO 2 SECONDS. THE RPM SHOWS THAT THE ENGINE IS REVVING BUT NO MOTION. THEN SUDDENLY THE VEHICLE WILL LURCH FORWARD. THE AMOUNT OF PRESSURE APPLIED TO THE ACCELERATOR DOES NOT MAKE A DIFFERENCE IN THE VEHICLE RESPONSE TIME. I AM VERY CONCERNED ABOUT THE SAFETY OF THIS VEHICLE AS THE VEHICLE WILL NOT ACCELERATE WHEN NECESSARY. I HAVE BROUGHT IN THE VEHICLE FOR REPAIRS OF THIS PROBLEM TWICE AND WAS TOLD THAT HYUNDAI KNOWS OF THE PROBLEM BUT BECAUSE THE ISSUE IS NOT EXTREME ENOUGH NOTHING CAN BE DONE. I DO NOT BELIEVE THAT THE VEHICLE CAN BE OPERATED SAFELY GIVEN THE CURRENT DEFECT.

NHTSA ODI 11348821

MOSTLY IN THE MORNING AFTER THE VEHICLE HAS SAT ALL NIGHT AND OCCASIONALLY THROUGHOUT THE DAY AFTER STOPPING AT RED LIGHTS OR WHEN LEAVING A PARKING LOT. THE VEHICLE WILL 'STALL, SHUTTER' OR HOWEVER ELSE YOU WANT TO DESCRIBE A RAPID JERKING MOTION WHILE TRYING TO ACCELERATE FROM A STOP. IT CAUSES A DELAY IN THE ABILITY TO EFFECTIVELY AND SAFELY MERGE THE VEHICLE INTO TRAFFIC AT TIMES.

I PURCHASED MY 2018 HYUNDAI TUCSON LIMITED 1.6L FORWARD DRIVE NEW IN NOVEMBER 2018. I STARTED EXPERIENCING PROBLEMS A FEW WEEKS AFTER MY PURCHASE. THE VEHICLE IS SLOW TO ACCELERATE AT TIMES AND OTHER TIMES THE VEHICLE LURCHES/ACCELERATES FORWARD AT A HIGH RATE OF SPEED WITH MY FOOT ON THE BRAKE PEDAL. FOR INSTANCE, I WAS AT A DRIVE THRU WITH MY FOOT ON THE BRAKE PEDAL AND MY TUCSON BEGAN TO ACCELERATE FORWARD. I WAS SO AFRAID THAT I WAS GOING TO HIT THE CAR IN FRONT OF ME THAT I TURNED THE VEHICLE OFF. ON NUMEROUS OCCASIONS IT HAS LURCHED/ACCELERATED FORWARD WITH MY FOOT ON THE BRAKE PEDAL. OTHER TIMES WHEN I BEGIN TO ACCELERATE AFTER STOPPING AT A STOP LIGHT THE VEHICLE JUST HESITATES TO MOVE AT ALL. IT IS VERY SLOW TO ACCELERATE FOR A TURBO VEHICLE. CONCERNING MY BRAKES, MY BRAKES ARE MAKING A HIGH PITCH SQUEALING SOUND. I HAVE TAKEN MY TUCSON IN FOR SERVICE FOR THE BRAKE ISSUE, AND I HAVE BEEN TOLD THAT THERE IS NOTHING WRONG AND THAT IS THE NOISE THAT TUCSON BRAKES MAKE. BRAKES DO NOT MAKE A HIGH PITCH SQUEALING NOISE FOR NO REASON AT ALL. ALSO, I TOOK MY TUCSON TO BE SERVICED FOR THE ENGINE/TRANSMISSION PROBLEM AND I WAS TOLD THAT THERE WAS NOTHING THAT THEY COULD DO ABOUT THE PROBLEM. THIS SUV IS A DEATHTRAP. THE 2018 TUCSON 1.6L NEEDS TO BE RECALLED AND THE ENGINE REPLACED WITH A 2.4L ENGINE AND THE BRAKE SYSTEM NEEDS TO BE REDESIGNED.
