2016 Hyundai Tucson acceleration problems

VEHICLE SPEED CONTROL

The vehicle severely shudders, jerks, and hesitates from a stop and while making a turn, during both acceleration and deceleration, making it entirely unsafe to drive. The vehicle has been completely un-driveable for the past 6 days. The check engine light illuminated, and on 4/9/26, the dealer documented a failed transmission judder test and kept the car, issuing a loaner. A temporary software patch failed after two weeks. Upon return, the dealer reported they were unable to recreate the problem, recommended returning when the vehicle demonstrates the problem more frequently, and refused to mechanically repair the dual-clutch transmission under my active original-owner 100,000-mile powertrain warranty, basically instructing me to continue to drive a seriously un-safe vehicle. Most recently, a yellow dashboard warning light illuminated, and the vehicle entered a dangerous 'limp mode,' severely restricting power and struggling to move before the light cleared after cooling down. The vehicle is completely un-driveable and parked.

Oil drains very fast even with regular oil changes and maintenance. The vehicle began shaking and then completely stopped with very little warning. Check engine light flashed for under 60 seconds then vehicle would not move forward on the highway creating a major safety hazard. Engine smelled hot and like burning rubber.

"On [XXX], my 2016 Hyundai Tucson (VIN [XXX] ) experienced severe engine power loss and mechanical noise under load while driving uphill, creating a dangerous safety situation. This occurred 2 days after a dealer visit (February 19, 2026) where an open KSDS Service Campaign (TSB HCE22-14-E600-TL, Issue 10D021) — directly related to engine monitoring — was left incomplete. The dealer subsequently denied an engine evaluation citing mileage over 150,000, despite the open campaign having no mileage restriction and despite a prior verbal commitment to cover repairs. Multiple follow-up attempts by phone, email, and WhatsApp have been ignored." INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I leased a 2016 hyundai tucson from Metcalf Auto Plaza [XXX]. Every week since then i have had to return the car for repairs. It got to a point where Neil suggested he can trade it for another but each and every vehicle i test drove to replace my car was NOT ready to be on the road but according to them every car had just got out the shop. Instead of trying to have issues resolved the mechanics decide to make "jokes" as if your pain and suffering is a joke. Since i did not want a trade in and wanted my car fixed instead Neil tried to tell me that this was my final offer which i declined because why not just fix my car? I went to talk to Neil in person September 9, 2025 about getting my car fixed and the frustrations i am having because having to return the car weekly and i havent had it for a month is outrageous. [XXX] i was driving the hyundai on the highway with my children in the car and the electricity to the car completely cut off but came right back on, i got off the highway and the car did it again and this time the wheel locked up and i almost wrecked the car. I called metcalf and the only thing they could tell me was they can tow my car to metcalf but me and my children had to find our own means of transportation. Every time i called to have my car serviced and told them about what i would hear and feel they could NEVER make the car "do it again". I am beyond frustrated, upset and terrified because i have been telling them about smoking coming from the engine, rattling noise etc. My kids lives were put in danger and the only thing they could say was "i apologize and we can tow the car to the shop". Did not care if we had transportation and have never offered to give us any after continously getting stranded in the car. Now the car is towed to their shop once again and the car wouldnt even turn over for me to get it out of the middle of the street. I was blocking traffic and had to have the police block INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA)

VEHICLE SPEED CONTROL

When accelerating, like taking off from a red light or through a turn, my car begins to shake like it’s unable to change gears correctly, and sometimes leads to the car stalling in the middle of the street and intersection putting my in danger of being hit from other drivers. It’s also happened that when I press the gas after being stopped at a light, my car RPM goes up but I don’t move and then the car jolts forward quickly. This has been happening for years and when I take it to Hyundai they tell me “that’s just how the car runs” which seems incredibly unsafe.

VEHICLE SPEED CONTROL

I had multiple occasions where the car would blink lates and make screaming noises when acceleration. The vehicle never had a smooth process of stopping and going. When stopped at a light, you could press the acceleration and it idle or not speed up than rev the RMPs and start to catch speed. It was very unsafe, I tried several attempts years ago at getting the vehicle maintenanced but only got rotors repaired from shaking and two other shops stating it was a recall and they could not service or fix the vehicle.

Oil consumption is excessive it has caused the engine to have a knocking noise even though routine oil changes have been up to date. Yes available for inspection. This may cause the engine to seize at any given point while in motion. No, I have not been able to take the vehicle to a dealership yet. No, vehicle has not been inspected. No, no check engine/warning light has turned on. Knocking noise began June 28th 2024.

My 2016 Tucson Sport with Eco Shift has a dangerous problem with the transmission. Intermittently It will not move when I give it gas. The RPMS go up to 6000 but the car wont move. Its the DCT transmission. Today I took it in for the 3rd time and I don't want it back until its fixed. This is a very unsafe vehicle to drive since you would not know when it would just stop shifting and driving. Have registered a complaint with Hyundai Motors as the service department does not know when the vehicle will be repaired.

1. My car will randomly not accelerate when the gas is being pressed. This has almost got me killed when making a left hand turn on more than 1 occasion now. The car also struggles with random shifting and power issues while going up steep hills at high speeds. 2. The front passenger side door and the rear drivers side passenger door just randomly stopped working with a week of each other. The rear wont open from the inside or outside. The front passenger side opens if you shake the handle back and forth multiple times (essentially trying to open it multiple times till it opens)

The contact owns a 2016 Hyundai Tucson. The contact stated that all four automatic windows failed to operate as needed. The front driver’s side window started failing and an appointment was scheduled with the dealer to repair the window. While testing the windows in the dealer parking lot after the repair, the front passenger’s side window fractured, and the dealer agreed to cover the cost of the repair free of charge. Over time, the rear windows started to lower independently, and the vehicle was repaired by an independent mechanic. In addition, the contact stated that the vehicle intermittently failed to accelerate while depressing the accelerator pedal. There was no warning light illuminated. The contact stated that the vehicle lunge forward while accelerating. The manufacturer was also notified of the failure. The vehicle was not repaired. The failure mileage was approximately 20,000.

The vehicle will not accelerate properly. Several times, I have been on the interstate, and the vehicle would barely increase in speed. Several instances have let to life threatening situations. Numerous times, I have gone to get on the interstate, and the vehicle would slow to nearly a stop, and even when having no other choice but to floor the gas pedal, it still would not accelerate. I've been forced to go off the road, in the middle of the interstate, so many times I've lost track. It's dangerous, and needs to be addressed immediately. I'm considering a lawsuit.

Upon acceleration onto highway or up a hill the car at times will rev and not shift or move /increase speed. Getting onto the highway I have had to pull into the shoulder until vehicle snaps out of it and decides to shift. Extremely dangerous & happening more often than not now.

WHEN ACCELERATING AFTER STOPPING, THE GAS PEDAL WILL BE PUSHED DOWN BUT CAR WILL STALL AND NOT GO. THE ENGINE WILL REV UP, BUT THE CAR DOES NOT MOVE AND THEN ALL OF A SUDDEN WILL ACCELERATE FORWARD. ALSO, WHEN COASTING IN RUSH-HOUR, ACCELERATING AFTER A STOP SIGN, THE CAR WILL MAKE JERKING MOVEMENTS. IT HAS BEEN TAKEN TO A HYUNDAI DEALERSHIP WHERE THEY TOLD ME IT IS A DUAL-TRANSMISSION SO I JUST NEED TO BE MORE AGGRESSIVE WITH IT WHEN TAKING OFF FROM STOP LIGHT/STOP SIGN. I KNOW THAT THIS IS NOT NORMAL AND MOST DEFINITELY NEEDS TO BE REVISITED AS THERE HAVE OBVIOUSLY BEEN ENOUGH COMPLAINTS AND HAS BEEN AN ISSUE PREVIOUSLY.

WHEN STARTING FROM A FULL STOP THE CAR HESITATES FOR 3 TO 5 SECONDS BEFORE MOVING; MAKING IT UNRELIABLE AND DANGEROUS TO PULL OUT. WHEN DRIVING SLOWLY IN TRAFFIC OR IN A PARKING LOT THE CAR BECOMES VERY JERKY AS IF RUNNING OUT OF GAS. THIS HAS HAPPENED SINCE THE DAY WE BOUGHT IT. TOOK IT INTO THE DEALER SHIP TO BE CHECKED OUT THEY TEST DROVE IT AND CHECKED IT OUT AND SAID IT IS WORKING THE WAY THAT IT SHOULD.WE HAVE LOST OUR CONFIDENCE IN THIS CAR AND FEEL THAT THIS IS A SAFETY ISSUE.THIS IS NOT ACCEPTABLE,

GOT THIS CAR AT THE DEALERSHIP IN JULY LAST YEAR. A FEW WEEKS BEFORE THIS HAPPENED YOU WOULD NOTICE A HESITATION FROM THE CAR TO MOVE FORWARD WHEN YOU PRESS THE GAS PEDAL WHILES DRIVING ON THE ROAD. THE ENGINE BEGAN TO MAKE LOUD KNOCKING NOISES ONE MORNING AND BROKE DOWN WHILE DRIVING ON THE STREET. GOT IT TOWED TO A HYUNDAI SERVICE SHOP AND THEY ARE TALKING ABOUT MAKING A "GOODWILL" REPAIR WHICH WILL END UP COSTING $4800. I HAVE READ MANY COMPLAINTS NOTED FROM THE 2016 TUCSON OWNERS WHO EXPERIENCED THE SAME ISSUES WITH THEIR CARS. THIS IS OBVIOUSLY A MANUFACTURING DEFECT. THE VEHICLE HAS BEEN RECALLED BEFORE FOR A TUCSON SECONDARY HOOD LATCH RECALL CAMPAIGN.

MY CAR KEEPS HAVING ISSUES WITH ACCELERATION. IT STRUGGLES TO MANUALLY SHIFT GEARS WHEN I TRY TO GO TO 40 MPH. I FEAR FOR MY SAFETY ESPECIALLY GETTING INTO HIGHWAYS SINCE I STRUGGLE TO KEEP UP WITH TRAFFIC UPON ENTERING. I HAVE TAKEN IT TO THE DEALER ALREADY AND PROBLEM PERSISTS.

HI. I REPORTED THE CRUISE CONTROL MALFUNCTIONING TO TWO DIFFERENT HYUNDAI DEALERS, SERVICE DEPT. THE PROBLEM VARIES FROM NOT BE ABLE TO SET THE SPEED, TO NOT BEING ABLE TO LOWER THE SPEED, TO NOT RESPONDING TO CANCEL, BECAUSE CRUISE CONTROL WILL NOT WORK PROPERLY . ALL ACTIONS ARE BY USING THE CONTROL TOGGLES ON THE STEERING WHEEL CONSOLE. IT IS AN INTERMITTENT PROBLEM, AS SOME TIMES IT WORKS FINE, AND FOR OTHER DRIVES IT WON'T ENGAGE AT ALL, OR WILL NOT DISENGAGE THE SPEED WHEN HITTING CANCEL. I CAN TAP THE BRAKE TO SLOW SPEED, WHICH CAN ALARM A DRIVER BEHIND MY LANE AND CAUSE AN ACCIDENT BEHIND ME. THE SERVICE STAFF CAN NOT GET THE CRUISE CONTROL TO DUPLICATE ON A VEHICLE TEST DRIVES. SO WITH THAT, THEY SAY THEY CAN NOT REPLACE THE STEERING LINKAGE, OR ANY PART BECAUSE THEY CAN NOT PROVE IT IS FAULTY. I EXPLAINED HOW IT IS NOT SAFE, ESPECIALLY ON A HIGHWAY WITH NATURALLY HIGHER SPEEDS TO CONSIDER. WITH FIVE REPORTS OF THE FAULTY CRUISE CONTROL ON FILE, AT DIFFERENT HYUNDAI SERVICE CENTERS, THE UNSAFE PROBLEM STILL EXISTS IN THE TUSCON 2016 SUV. I HAVE PAPERWORK SHOWING REPORTED SAFETY CONCERNS SEPT 18, 2018, MAR 27, 2019, JUNE 3, 2019, AUGUST 15, 2019, OCT 16, 2019. PLUS A PERSONAL VIDEO OF PUSHING AND TOGGLING THE CONTROLS WITHOUT CRUISE RESPONSE.THAT IS OVER A YEAR OF THE REPORTING THE MALFUNCTIONING SPEED CONTROL. IT IS UNSAFE WITH NO SOLUTION.
