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.

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

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.

DP22003 · Loss Of Motive Power
Opened Sep 12, 2022 · Closed Dec 12, 2023
Status: closed (inferred from source dates) · Engine
The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing. There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in NHTSA's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, NHTSA does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP22-003. To review those complaints and the additional complaints ODI added to its evaluation which are cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
