2021 Kia Niro problems
The Kia Niro (Korean: 기아 니로) is a compact crossover SUV (C-segment) manufactured by Kia since 2016. It is an electrification-focused vehicle, offering three versions: hybrid, plug-in hybrid and battery electric variants.
First generation (DE; 2016)
The first-generation Niro was introduced in 2016. Based on the same platform as the Hyundai Ioniq, Kia opted to use dual-clutch transmission instead of the more traditional continuously variable transmission found in most other hybrids to offer a more engaging driving experience.
The size is between the Stonic and Sportage, and very close to the XCeed. In Europe, the Niro was launched in a choice of seven colours and either 16- or 18-inch wheels. It was the first Kia model to feature Android Auto, available from its launch, while Apple CarPlay was made available towards the end of 2016. Seven airbags were included as standard, along with other safety features including autonomous braking, smart cruise control and lane departure warning to name a few. Noise reduction was a key development focus, with Kia achieving a quieter cabin by use of increased front structure insulation and the use of acoustic windshield glass.
Full production started in May 2016 in Hwaseong, Gyeonggi, South Korea, with European sales from the third quarter of 2016.
A plug-in version was launched in the United Kingdom in the end of 2017, and in the United States in the beginning of 2018, with an electric version launched in 2018. Towards the end of 2018 and start of 2019, sales of the Niro PHEV ranked highly in Denmark and Sweden in a list of top plug-in car sales.
The Niro received a facelift in 2019 which included changes to the front and rear bumpers, as well as new headlights and color choices. Unlike the prototypes, no production version was ever offered with four wheel drive.

Common 2021 Kia Niro problems
The Kia Niro, including the 2021 model, has been commended for its exceptional reliability, with very few reports of mechanical issues. However, some common problems have been reported by owners.
- Door Handle Broke Off: The most-reported problem with the 2017 Kia Niro is the door handle breaking off, with an average mileage of 12,000 miles. This issue seems to be specific to the 2017 model, as no similar complaints have been reported for the 2021 model.

- Summary: I was backing out of a tandem parking spot in a private garage and got too close to a pillar, and tried to pull forward into the spot. It felt like the car got snagged on the pillar, but while pulling forward slowly, the gas pedal snapped off and the car accelerated quickly and uncontrollably. I was able to avoid hitting other cars but drove straight into a concrete wall despite immediately braking. I'm relatively uninjured, but if it had happened in a less controlled environment and/or I hadn't reacted as quickly, there could have been serious injuries to myself or others. There was no indication of an issue prior, and the car is currently in storage with my insurance company and will be appraised next week. I have photos of the broken pedal.

But their is no timeframe they have or when this additional part will be available. The dealership has the fuses & Harness for the HCA replacement, but needs this additional part. I asked what the # of this part is or name, but all they would tell me TBT.

- VIN: KNDCB3LC4M5
- Components: UNKNOWN OR OTHER
- Summary: Vehicle is available for inspection upon request. HEV light lit up on dashboard and a warning message was displayed alerting me to immediately pull over and turn off the vehicle. At the same time the vehicle was not responding and acceleration became troubling and with marked hesitation. After waiting several minutes I attemped to turn the vehicle on again but the warning light and alarm went off. Vehicle is currently at the dealership but they have not offer a solution or even a temporary remedy.
POWER TRAIN PROBLEM
- Date Of Incident: 2023-07-21
- VIN: KNDCM3LD6M5
- Components: POWER TRAIN
- Summary: The contact owns a 2021 Kia Niro. The contact received notification of NHTSA Campaign Number: 23V534000 (Power Train); however, the part to do the repair was not yet available. No further information was provided. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.
VISIBILITY PROBLEM
- Date Of Incident: 2022-09-14
- VIN: KNDCE3LC4M5
- Components: VISIBILITY
- Summary: While driving on a major highway, my sunroof suddenly exploded. Luckily the screen was pulled shut otherwise I would have been covered in glass. I was able to drive to the next exit and park the vehicle to then get out and observe the damage. There was a gaping hole in the sunroof. I called a tow who brought me to a Kia dealership. I explained what happened and after inspecting the car the dealership told me it was road debris that caused the issue. I did not see or hear anything hit my car prior to the explosion of the sunroof and I question their findings that it was debris related.
BACK OVER PREVENTION PROBLEM
- Date Of Incident: 2021-07-29
- VIN: kndce3lg9m5
- Components: BACK OVER PREVENTION
- Summary: I'm a new Niro Ev driver. The VESS noise when reversing the vehicle is very loud. It is too loud, I live in close proximity to neighbors and have to get up early for work and the sound is a major nuisance, I would not want a neighbor that has this car . I understand VESS in place for safety but the reverse backup beeping is just a step down from a garbage truck backing up, especially in the silence of a residential neighborhood in the early AM hours. Furthermore, I and others as seen on web forums will reverse faster than we normally would do to be able to take the car out of reverse as quickly as possible to stop the blaring beeping. This creates its own risk, as if there is less time to react if there is a pedestrian behind the vehicle. The volume of the noise should be greatly reduced. It is also unnecessary noise pollution. Kia, please fix this.
VISIBILITY/WIPER PROBLEM
- Date Of Incident: 2021-07-04
- VIN: KNDCB3LC6M5
- Components: VISIBILITY/WIPER
- Summary: There is a silver strip of "trim" running completely across the dashboard just above the radio controls. It is so reflective that a glare occurs periodically throughout the day when the sun hits it. It's so bad that it blocks the left side mirror with the reflection and can even blind the driver. This needs to be addressed by Kia. Easy solution is to have Kia remove the strips, paint them black, and re-install them.

Just bought our second Kia Niro. We got one 11 months ago and we absolutely love it! My husband and I even argued about whose turn it was to take it, so I went out and bought my own. The gas savings are fabulous and it's incredibly roomy and comfortable. Plus, the price is unbeatable!

Here's a head scratcher: I recently drove 7 hours mainly on the highway, using mainly cruise control, and I averaged 44 mpg (this S Touring's average highway mileage is 40 mpg). However, my average city driving never gets more than 38 mpg (the S Touring's average city mileage is 44 mpg). I previously owned a 2013 Prius C, so I know all the tricks to increase gas mileage. Unlike the Prius C, where you entered your cost per gallon every time you filled up, the Niro doesn't have that option. I have no idea how the car figures out the correct mpg without it. I got a pearl white Niro S. I'm not a fan of white, but in this case, there are enough black accents to satisfy me (and I love a black interior). Despite a decent, not great, Harman Kardon stereo system, you may not be able to play anything mellow on the highway due to the cabin's road noise (city driving is fine). Thankfully, I like my music with a beat, and the Harman Kardon speakers come through. The seats are comfy, and I love the heated seats (which also heat your lower back). I pulled a back muscle, and the ONLY time I felt comfortable was in the driver's seat thanks to the heat and lumbar adjustment. The interior is well-appointed, and the seats are an unobtrusive leather/cloth combo. The air intake, which keeps the electric battery cool, is positioned on the side of the back seat, which is great. My Prius C had it positioned under the rear passenger seat, which could easily be blocked by legs, long dresses, and stuff you might throw in the floorboard. The cargo area is big enough for me to throw in a bike, so I'm happy. The Touring S also knows when you are approaching the car (if you have your keys on you): The rearview mirrors unfold, and the door handle lights up. Also, if you have your keys on you, the rear trunk automatically unlocks. This is very convenient if your arms are full. Would I buy it again? Possibly.I might consider revisiting the Toyota Rav4 hybrid next time, although the passenger area does feel smaller and I would have to pay a lot more for all the bells and whistles that I have on my Niro S Touring. One year later, in 2020, I still agree with everything I said above. I am still enjoying driving my car and have had no surprises. I have no desire to trade it in for another hybrid. I have given it 4 stars because the car has been very reliable so far and I truly enjoy driving it.

I recently purchased the Kia Niro and I am absolutely loving it! The sticker claims 49/highway City 55, but I was able to achieve an impressive 59.2 miles per gallon on a 227 mile drive from the dealership. I decided to use the best grade gas and it drives like a dream! The Sport mode is a personal favorite, but I mostly drive it in regular mode. When entering a highway from the on ramp, I slide it into Sports mode and the acceleration is fantastic, making merging onto the highway a breeze. I frequently drive 300 miles in three days for work and the Niro is perfect for my needs. It has great storage and the back seats fold down flat, making it incredibly versatile. The seats are comfortable, even in the back, and the size is just right for me. I am already planning on getting a Niro plug-in hybrid when I retire. With that car, you can drive 26 miles on electric along with the gas mode. Who knows, in another 10 years it may even be 100 miles on electric only! Overall, I highly recommend the Kia Niro to anyone in the market for a new car.

This is a great first hybrid! It's affordable and comes with a lot of safety features. The only downside is that it's a bit smaller than I would prefer.

12k miles and a year of ownership; this car has been an excellent value for the money. It gets a crazy 46-54 MPG [depending on temperature] and has plenty of room inside with great comfort and safety features. The seats are comfortable for long hauls and the Harmon system is rocking. The android auto is also quick to respond. Both the interior and exterior are holding up well and the new car smell is still present even after a year. The surface and buttons still look new and the ride has softened a little as it has settled over 12k miles of driving.

Other years of Kia Niro
Are you having problems with your 2021 Kia Niro?
Abel Fahey 2025-01-20
Last Thursday, while driving home from work, my 2017 Kia Niro instructed me to immediately pull over and call Kia's roadside assistance. Unfortunately, this has happened at least three times in as many years, forcing me to pull over and get my car towed to my local Kia dealer. However, I am grateful that each time, the repairs have been covered under warranty. Despite this, I have been left stranded on the side of a hazardous and busy freeway during warm weather. As the original owner of my Niro, driving less than 10,000 miles each year, I am disappointed that this has happened repeatedly. I believe that my car is a lemon. After three years of patiently believing the Kia service departments when they tell me that my car has been fixed, only to be stranded once again, I have come to the realization that the only professional recourse would be for Kia to refund my money.

I've been driving this car for 3 years now and it has an impressive fuel efficiency of 543 Mpg. However, I've been experiencing some technical issues lately and unfortunately, Kia is no longer covering the repairs since it has exceeded 60k miles. Despite this setback, I have taken this car on some amazing adventures, from California to New York and back, and it has performed well. Overall, it's a good car with some minor annoyances.

I was hoping to use this car for my daily errands around town. I had read that the 2019 Kia Niro had an average city rating of 51 mpg, but unfortunately, I have only been getting an average of 25 mpg for short trips (such as my 3-mile roundtrip to work). For slightly longer commutes (like my 12-mile roundtrip to school), I have been getting 39 mpg, even though I have been driving very conservatively. I have noticed that the instant fuel economy is 9.8 mpg and I have had to drive very slowly, causing a line of cars to form behind me. I am planning to check the gas mileage manually to see if there is an instrumentation problem. It seems like the engine is being used when the electric motor should be running the vehicle at slow speeds. I took the car to the dealer to have it checked out, but they found nothing wrong with it. While I am not sure if I will keep this car, I am definitely not happy with the Kia Niro.

I recently reviewed the LX with standard package. While the car is great for city driving, the cargo space is quite small. I was only able to fit 2-24 pack bottled water and 2-24 pack Pepsi, and the rest of my groceries struggled to fit. It may not be the best option for big grocery trips for a family of 5, as even my compact Hyundai Accent has twice the trunk space of the Kia Niro. Additionally, it may not be the best option for Ikea trips, as a compact car would be able to carry much more. The acceleration is also poor in comparison to other SUVs of the same size, and you will have to really step on it to reach the normal tollway speed of 70-75 mph here in North Texas. Furthermore, there is no extra charger/usb port for back seat passengers, unlike other new vehicles. The car does come with a Sirius package, but it's only free for 3 months, and there is no other entertainment option. The 3 seats in the back are quite small, and 3 normal weight teenagers would struggle to fit. While this may not be the best option for a road trip or for a family of 5, it is still a great car for city driving. It may not be the most efficient option for rideshare due to the lack of cargo space. However, the warranty is good, as Hyundai/Kia have great warranties. I hope this review helps you make an informed decision. Remember to shop around and do your research before making a purchase.
