   This complaint supplements a previously submitted report filed today, June 18, 2026, (Original is Complaint Number: 11845044) regarding the same vehicle and condition (TSB ELE234 drive unit rumble noise). The correct VIN for this vehicle is [XXX] — a 2019 Kia Niro EV EX Premium, 138,457 miles. I am filing on behalf of the vehicle owner, [XXX], who has authorized me to act as his advocate. The owner is a Ukrainian speaker and I am assisting with all documentation and communications. In addition to TSB ELE234 (drive unit motor rumble, April 2021), this vehicle is also subject to Kia Service Action SA512 (April 2023): Inverter Coolant/Debris Flushing for the "Refill Inverter Coolant" cluster warning, affecting 2019–2022 Niro EVs produced May 10, 2019 through October 4, 2021. SA512 has also not been confirmed as completed on this VIN. CARFAX records document multiple authorized Kia dealer visits — at Roseville Kia and Folsom Lake Kia — between 2019 and 2022, during the period both ELE234 and SA512 were active and applicable. Neither service action was applied during those visits. This filing requests that NHTSA investigate both the safety implications of the ELE234 drivetrain defect and the broader pattern of authorized Kia dealers failing to notify owners of and apply active service bulletins during routine service visits on affected VINs.

   Our 2019 Kia Niro EV (approximately 138,000 miles) exhibits an abnormal rumble/growling noise from the front drive unit while driving slowly in "D" range and when accelerating or decelerating between 0–25 mph. This symptom matches exactly the condition described in Kia Technical Service Bulletin ELE234 (Rev. 1, April 2021): "Drive Unit Inspection & Replacement for EV Motor Rumble Noise," which covers all 2019MY Niro EV vehicles produced from December 5, 2018. To our knowledge, TSB ELE234 has never been performed on this vehicle. The repair involves replacement of motor/roll mount brackets and, if necessary, traction motor or reduction gear replacement. Kia has a documented, tiered repair procedure for this exact issue with assigned labor operation codes. The failure presents a safety concern because drivetrain noise at low speed can precede loss of drive power or sudden drivetrain failure, which creates a hazard in traffic, intersections, and during highway merging. Despite the existence of this TSB since April 2021, NHTSA appears to have few or no formal complaints logged for this specific defect, meaning it has not triggered the regulatory scrutiny it warrants given the documented widespread nature of the issue. I am requesting that NHTSA investigate whether a formal recall of affected 2019 Kia Niro EV vehicles is warranted for this drivetrain defect.

   1. Failed Component/System: EV plastic charging door does not open using the electronic unlock mechanism on the key. Unable to charge EV vehicle due to this fundamental failure. IMPORTANT: There are no manual override mechanisms provided by the manufacturer - KIA to open this charging door. This makes the EV both unsafe and unusable since it cannot be charged. 2. Safety Risk: Unable to charge an EV vehicle is a fundamental EV electrical system component failure that can create an unsafe situation since it occurs without any warning and leave the car owner stranded. The Manufacturer - KIA has not provided any manual fail safe/override mechanism to open the charging door manually. This is also a fundamental safety issue since the failure occurred without any warning lamp/other indication to the owner. IMPORTANT: Other KIA NIRO EV owners have complained about the same issue in online forums. Refer attachment - [XXX] 3. Dealer Problem Reproduction: NO since dealer demands a $299.99 diagnostic fee. Multiple attempts to contact the dealer and manufacturer KIA to waive the diagnostic fee were unsuccessful. 4. Manufacturer/Police/Insurance Inspection: No. KIA refused to deal with this issue under the KIA 10-year/100,000-Electric vehicle (EV) system warranty even though the warranty description mentions all internal parts. Reference: KIA Case No. [XXX]. NOTE: KIA does not allow the case history to be retrieved from their manufacturer portal because they have closed the case. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure? NO 6. When did they first appear?

   While I’m driving a turtle light randomly illuminates and the car shuts off. The car shuts off from a few seconds up to a minute so far. I have taken it to Kia McDonough Ga and to no avail nothing: they had my car 2 months and by the time they did the diagnostic “the computer box reset”. Why let it sit for a diagnostic when all they are doing is connecting to a computer. I provided them videos and pictures and nothing. This is a danger any passengers, other drivers, as well as myself. The times are random and once the light comes on it’s off. Battery is new, battery is charged.

   Car made loud whinning noise for 6 months, due to defective transmission. KIA refused to fix because car was out of warranty- but has TSB: ELE234. My extended warranty did not cover because it was a known defect from KIA.' Car stopped working, transmission was repaired. Please see below attached 16k invoice.

   On June 28, 2022, I set my Juicebox Pro 40 charger to charge my car overnight. The car did not charge and I discovered that the breaker had tripped. I tried resetting the breaker and it immediately tripped again. I noticed a burning smell in the garage in the vicinity of the charger after attempting to reset the breaker. There was discoloration on the unit box. I then unplugged the unit at which point I was able to reset the breaker without it tripping. I concluded that the unit was unsafe to use and I returned it to ENEL. I bought a new one while I waited for warranty service on the old unit. I have not tested the old unit since it was repaired by ENEL. It was my judgment at the time, and remains so, that the unit presented a fire hazard.

   There’s motor rumble due to a misalignment of the traction motor and reduction gear. It’s a known issue with these vehicles and a technical bulletin was issued but no recall. I’ve brought the vehicle in twice and the first time the dealer told me there was nothing wrong. Now a year later they admit it is wrong and is unsafe to drive without a $10k replacement.

    - While driving, we received a notice on the dashboard to "stop driving and check regenerative brakes". Simultaneously we lose 95% of our braking power and all of the acceleration. Slamming on the brakes all the way to the floor provided some minor braking ability, but it was significantly diminished and frankly terrifying. We turn the car off, turn it back on again, and everything seems totally normal. - We cannot recreate the error, but we call the dealership. They say they can get us in in a week to service us. As this is our only car we keep driving it cautiously. - This happens again once more, before we bring it into the dealership. - The dealership runs a bunch of tests, tells us its the 12V battery, replaces the 12V battery, charges us $500 and tells us its fixed. - one week later (today) the same thing happens. Clearly it's not fixed, but even if it had been fixed, why is so much of the braking tied to the 12V? The dealership cannot get us in for days and is suggesting this may not be covered under our warranty.

    This is a published TSB but it doesn't appear when searching for this vehicle. I have to search in google for specific phrases to find this on your website. "DRIVE UNIT INSPECTION & REPLACEMENT FOR EV MOTOR RUMBLE NOISE " Kia Niro EV: [XXX] Hyundai Kona EV: [XXX] Known issue with many customers reporting Kia and Hyundai Motor failures. But since it is not an official recall campaign, it doesn't pop up when researching Kia Niro, Soul, Hyundai Kona, Ioniq EVs. Many consumers report that service centers will gaslight, dismiss, downplay, or falsely blame on brakes, rotors, other unrelated parts. Some have reported they flat out refuse to work on their car even if they bought it there, stating that they don't have technicians trained for EV service. And when/if we are lucky enough for service departments to do repairs, the parts are on backorder. They have to replace brackets/mounts that never resolve issue until finally replacing the motor/gearbox. Often the problem comes back in a few months as the replacement parts don't actually address the root causes. This should certainly be a full recall campaign that the public is made aware of. A final note here on the problem with these extensive complicated long services, is that people are without a vehicle during the whole process. Dealerships and Manufacturers pass the buck, point the finger to each other. Dealerships don't offer loaners, they say check with Kia for rental reimbursement. No one who plans a budget for a new car payment, ever factors in $2-3000 for months of car rental payments that the Manufacturer won't pay until the service is fully finished.

    During driving or while parked, the vehicle will shut off power brakes, and display an error "Stop Vehicle and Check Regenrative Brakes". When the power brakes shut off, the brake pedal location and feedback change sharply and the responsiveness is severely impaired. This error can occur at any time, which is very dangerous especially at highway speeds or when coming to a stop. I have let an authorized Kia dealership inspect the car for 31 days and did not see the issue. I took the vehicle back, and it happens frequently, so I drove it in with the issue active again and they have had it for another 7 days so far after seeing the issue actively reported. The first occurrence occurred at approximately 18000 miles, about 2.75 years of operation on May 12, 2022. since then, it occurs about twice per week. These trouble codes are asserted when this happens: C1360(81) Raw code: 536081 ECU: Adaptive cruise-control Status: Test failed, Confirmed, Warning indicator requested C1741(81) Raw code: 574181 ECU: Adaptive cruise-control Status: Test failed, Confirmed, Warning indicator requested C2405(27) Raw code: 640527 ECU: ABS control unit Status: Test failed, Confirmed, Warning indicator requested

    SINCE THE BEGINNING OF APRIL 2021, AND JUST AFTER THE ODOMETER TURNED OVER TO 10K MILES, MY E-NIRO HAS BEEN EXPERIENCING A BIZARRE BEHAVIOR THAT POSES A POTENTIALLY SERIOUS SAFETY RISK. THIS TAKES THE FORM OF TOTAL LOSS OF ACCELERATION POWER FOR A FEW SECONDS, USUALLY AFTER DEACCELERATING TO A NEAR STOP (USUALLY, BUT NOT ALWAYS, WHEN USING THE PADDLE ON THE LEFT SIDE OF THE STEERING WHEEL TO REGENERATIVELY BRAKE) THEN PRESSING THE ACCELERATOR PEDAL, OR WHEN MAKING A VERY TIGHT TURN (E.G., INTO A PARKING SPACE). POWER RETURNS A FEW SECONDS AFTER THE PAUSE, AND I CAN CONTINUE. I HAVE BEEN DRIVING THIS VEHICLE FOR ALMOST 2 YEARS, AND THERE HAS BEEN NOTHING SIMILAR HAPPEN PRIOR TO THE START OF THIS BEHAVIOR AT THE BEGINNING OF APRIL. THE VEHICLE HAS BEEN GARAGED AND CHARGED NORMALLY AND NO EXTREME WEATHER CONDITIONS OR OTHER FACTORS HAD BEEN PRESENT BEFORE THIS WAS FIRST NOTICED. INSTANCES NOW SEEM TO BE INCREASING IN FREQUENCY THE PAST COUPLE OF WEEKS, HOWEVER. ON 2 OR 3 OCCASIONS, THE VEHICLE ACTUALLY BACKED UP A COUPLE OF FEET (ON LEVEL GROUND), WHICH WAS FRIGHTENING BOTH FOR ME AND THE AUTO BEHIND ME AND COULD HAVE RESULTED IN AN ACCIDENT. ON THE OTHER OCCASIONS, BEING MOMENTARILY UNABLE TO ACCELERATE IS ALSO CONCERNING (FOR INSTANCE WHEN IT DIES HALFWAY INTO A TRAFFIC CIRCLE OR IN AN INTERSECTION WHEN STARTING TO MAKE A TURN). ALTHOUGH NO WARNING LIGHTS WERE INITIALLY SEEN, I NOW GET A "CHECK ELECTRICAL SYSTEM" WARNING WHEN THIS POWER LOSS HAPPENS, SOMETIMES EVEN WHEN THERE HAS BEEN NO LOSS OF POWER TO THE MOTOR. THE WARNING LIGHT DISAPPEARS AFTER THE VEHICLE HAS BEEN TURNED OFF AND ONLY REAPPEARS WHEN ANOTHER INCIDENT OCCURS. I HAVE ASKED THE DEALERSHIP SERVICE DEPARTMENT ABOUT THIS, WITH NO FIRM RESPONSE YET. I'M REPORTING TO DOCUMENT THIS IN THE EVENT OTHERS EXPERIENCE THIS PROBLEM.

    MY BRAKES FAILED AS I TRIED TO STOP FOR A TRAFFIC LIGHT ON A CITY STREET. THERE WAS A CAR ALREADY STOPPED AT THE LIGHT, WHICH I BUMPED INTO. AS I WAS DEPRESSING THE BRAKE PEDAL, IT 'GAVE', AND THE CAR CONTINUED TO MOVE FORWARD; I WAS UNABLE TO STOP. LUCKILY, I HAD ALREADY SLOWED CONSIDERABLY PRIOR TO THE BRAKES FAILING, SO NO ONE WAS HURT AND THERE WAS MINIMAL DAMAGE. THE OTHER DRIVER LEFT THE SCENE WITHOUT EXCHANGING INFORMATION, AND NO POLICE REPORT WAS FILED. THE KIA SERVICE TECHNICIAN WAS UNABLE TO FIND ANYTHING WRONG WITH THE VEHICLE: NO CODES SHOWED UP REGARDING ANY PROBLEMS; NOTHING WAS IN THE ONLINE HISTORY REPORT; NO LEAKS OR DAMAGED BRAKE COMPONENTS WERE OBSERVED; TEST DRIVING FAILED TO REPLICATE THE PROBLEM. ALTHOUGH HE SAID I COULD PICK IT UP, SO FAR I HAVEN'T ' I WON'T DRIVE IT IF THE BRAKES ARE NOT RELIABLE! THE ACCIDENT COULD'VE HAPPENED ON THE HIGHWAY AT HIGH SPEEDS; SOMEONE COULD'VE BEEN GRAVELY HURT OR KILLED... I FOUND AN ARTICLE ONLINE THAT DESCRIBED A RECALL OF KIA OPTIMAS FOR WHAT SOUNDS LIKE THE PRECISE PROBLEM: THE 'SOFTWARE FOR FORWARD COLLISION WARNING (FCW) MAY PREVENT THE AUTOMATIC EMERGENCY BRAKING (AEB) SYSTEM FROM ENGAGING AS EXPECTED WHEN FCW SENSES A POTENTIAL COLLISION WITH A STATIONARY VEHICLE.'

I THEN CALLED THE KIA CUSTOMER SERVICE NUMBER IN THE ARTICLE I FOUND, AND WAS TOLD THEY WOULD INITIATE AN INVESTIGATION; SO FAR I HAVEN'T HEARD BACK FROM THEM.
