ISSUE IS NOTICEABLE HESITATION WHEN PULLING OUT FROM A STOP, ESPECIALLY IF TURNING FROM A STOP OR PULLING OUT QUICKLY. RPS WILL REV AND THEN CAR WILL FINALLY MATCH RPMS AND TAKE OFF SUDDENLY.

HAS AN ECO BOOST/SPORT MODE TRANSMISSION. WHEN STARTING FROM A STOP, SUCH AS AT A RED LIGHT, STOP SIGN OR EVENACCELERATING FROM A SLOW DOWN THERE IS A LAG IN THE ENGAGEMENT OF GEARS THAT CAUSES THE VEHICLE TO "STALL" IN THE INTERSECTION. IT REVS AND FEELS AS IF THERE IS POWER, THE TRANSMISSION JUST DOESN'T ENGAGE. IT CREATES AN INABILITY TO MOVE THE VEHICLE WHILE IN TRAFFIC OR WHILE ENTERING TRAFFIC. THIS IS VERY SIMILAR TO, IF NOT IDENTICAL TO THE TRANSMISSION RECALL ANNOUNCED IN 8/30/2016 FOR, I BELIEVE, THE SAME TRANSMISSION IN OTHER MODELS OF THE 2016 HYUNDAI TUCSON.

I PURCHASED A HYUNDAI TUCSON IN SEPEMBER OF 2016 NEW. I NOTICED RIGHT AWAY THAT I COULD NOT SEE VERY WELL AT NIGHT. THE HEADLIGHTS ARE AIMED AT THE GROUND 2-3 CAR LENGTHS IN FRONT OF THE BUMPER. WITH THE HIGH BEAMS ON YOU CAN SEE THE DEFINITE LINE BETWEEN LIGHT AND DARK APPROX 4-5 CAR LENGTHS IN FRONT OF THE BUMPER. WHEN CARS ARE APPROACHING ON AN UNDIVIDED ROAD, THE VISIBILITY IS REDUCED EVEN MORE FROM THE GLARE OF THE ONCOMING LIGHTS. I HAVE HAD 2 CLOSE CALLS WHERE I ALMOST HIT A PEDESTRIAN WALKING ON THE EDGE OF THE ROAD WITH DARK CLOTHES ON. I HAVE TAKEN THE VEHICLE TO AUTOFAIR HYUNDAI IN MANCHESTER, NH ON TWO OCCASIONS TO HAVE THE HEADLIGHTS ADJUSTED TO CORRECT THE PROBLEM. I QUOTE THE RESPONSE,"CUSTOMER WOULD LIKE US TO ADJUST THE HEADLIGHTS, STATES HE CAN NOT SEE AT NIGHT, CAN SEE IF WE CAN ADJUST THEM, MISC PER STATE LAW WE CANNOT ADJUST THE HEADLIGHTS ABOVE WHERE THEY ARE CURRENTLY. 6686 ISP" THE INSURANCE INSTITUTE FOR HIGHWAY SAFETY'S EVALUATIONS SAYS "MANUFACTURERS AREN'T PAYING ENOUGH ATTENTION TO THE ACTUAL ON-ROAD PERFORMANCE OF THE BASIC EQUIPMENT,WE'RE OPTIMISTIC THAT IMPROVEMENTS WILL COME QUICKLY NOW THAT WE'VE GIVEN AUTOMAKERS SOMETHING TO STRIVE FOR." FOR 2017, VEHICLES WILL NEED GOOD OR ACCEPTABLE HEADLIGHTS IN ORDER TO QUALIFY FOR THE INSTITUTE'S HIGHEST AWARD, TOP SAFETY PICK+.THAT'S REAL NICE OF THEM. WHAT HAPPENS TO MY 2016 MODEL? I WANT MY VEHICLE RECALLED AND REPAIRED. WHY SHOULD I HAVE TO WAIT AND BE FORCED TO BUY A 2017 MODEL IN ORDER TO HAVE A SAFE CAR AT NIGHT?

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.
