2019 KIA NIRO Complaints

When coming to a stop, the car will jerk forward with a loud clack sound. Sometimes it's mild, but other times it is as if the car had been rear-ended, causing it to lurch forward abruptly. There is no rhyme or reason to when it will happen, but it is always when coming to a stop, usually at a very slow speed.

The rubber pad on the brake pedal came off almost causing me not to be able to stop effectively. What was left is a small steel pedal which sometimes is challenging to feel.

Within the first 6 months of owning our 2019 Kia Plugin Hybrid, we started experiencing a clunk with a lurch when accelerating from a stopped position. The issue became progressively worse over time - increasing in frequency and severity. The car has been to the Kia Lupient dealership in Brooklyn Park, MN multiple times for this issue. At our most recent visit on November 7th, 2022, the service advisor acknowledged that the issue may be due to shipping the vehicle with the wrong transmission fluid. The transmission fluid was replaced with the correct fluid. However, we experienced the issue again on December 2, 2022. Could the wrong fluid have caused permanent damage to the transmission? This Technical Service Bulletin (https://static.nhtsa.gov/odi/tsbs/2020/MC-10174520-0001.pdf) indicates that could be true. We are pursing arbitration with the dealership.

I was in a car accident (I t-boned a guy that ran a red light in front of me) at about 20 mph but no airbags deployed. My car is a total loss and I have a concussion from hitting my head on the window plus contusions along the path of the seatbelt. I suspect something could be wrong with the airbags considering they failed to deploy despite a collision that totaled the car. I wonder if I might not have got a concussion had they deployed. Police responded and commented about my airbags failing to deploy and my insurance is inspecting the car this week.

I have a used 2019 Niro PHEV. I started getting a loud jerk when starting from a full stop. At first it started happened in EV mode only but I've had it happen in Hybrid mode a couple of times ( not sure if the engine is actually working or just on for Heating). The sound and jerk can best be described as what happens when you drive a stick shift and you pull the clutch too quickly in first gear without any gas and the car jerks forward. It also feels like I've been rear ended. The car feels unsafe the drive. There were no warning lights. Dealer hasn't reproduced it yet. I just brought it in. Please see these forum posts about this issue. Many others are experiencing this: https://www.kianiroforum.com/threads/brand-new-2019-phev-loud-jerking-noise-when-starting-from-full-stop.8740/ https://www.kia-forums.com/threads/occasional-hard-loud-shift-from-start-on-new-niro-phev.342780/

The vehicle has an intermittent jerk/clunk sound when accelerating or coming to a stop. Occasionally it can feel as if the clutch is coming engaging/disengaging roughly and cause passenger's heads to shake forward. In a few instances there has been a delay when pressing on the brakes to initiate stopping before the vehicle, this momentary loss of control is alarming. It feels as if the clutch and brakes did not react to the pedal immediately. I have taken the vehicle to the Kearny Mesa Kia dealership to diagnose the issue on 3 separate occasions starting from 2 months after purchasing the vehicle. On the most recent visit they have diagnosed that dual clutch failed a calibration test - it is unclear if they performed this test on the previous visits. Repairs have not yet been performed as I am disputing the out of warranty claim by the dealership

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

Obnoxious eye and lung burning fumes in the car when turning the heater on. It was so from the day I bought it. Many owners have reported it also on Kia nitro forum . I drive in the cold without the heater or leave the window open to let the fumes out. It’s a health hazard and seems to relate to their heater core or it’s insulation material. Dealer and Kia claim nothing is wrong. It’s a health and safety hazard in need of immediate solution and recall. Also car’s steering column make a wheezing or rubbing noise when turning the wheel. Dealer says it’s normal. It’s not a safety hazard yet. But I have never driven or heard any other car with persistent rubbing noise it it’s inside the car’s steering column. Whatever is rubbing will eventually wear out posing failure and safety risk. A voluntary recall may be in order.

12 volt starting battery (Lithium Ion Polymer) pn 37507-G2120. battery swollen and will not take charge (2.5 years old) 15,000 miles on vehicle. This battery powers dash and all related safety systems. Dealer refuses to look into problem as batteries are on national back order status and cannot fix due to parts availability. 3 dealerships have been contacted, all have been making excuses for other systems at fault to avoid recognizing battery is defective. I have been without use since Mar2021.

There is a pause upon acceleration from a stop (unresponsive). Then the vehicle will lunge forward and make a loud noise. For both driver and passengers, it can be quite startling and feels as though the car has been hit from behind. This started happening in the fall of 2021, when the car was about two years old with about 18,000 miles. It has happened about a dozen times in the six months since first noticed. It seems that this may be a software issue related to the hybrid system - a lag in triggering which motor to use for acceleration.
