   My 2023 Kia Niro Hybrid has a recurring intermittent electrical defect. Warnings appear together: Check Hybrid System, Check Engine, Forward Collision, Rear Cross-Traffic, Lane Keeping, Driver Attention, ESC, Brake, Auto Hold. They appear and persist while driving, during which stability control, automatic emergency braking, lane keeping, and related safety assists are disabled. Once, the vehicle would not start and was temporarily disabled, recovering after several minutes. This creates risk from loss of all electronic safety assists in traffic and from the vehicle failing to start when needed. Stored codes show lost CAN communication among multiple modules: U0101, C1611, C1693, U0111, U0164, U0293, U042B, U1341. Confirmed by two Kia dealerships over five warranty visits. V1–2 (Coughlin Kia, Dublin OH): software updates; warnings returned. V3 (Ricart Kia, Columbus OH): inspected, released OK; warnings returned. V4 (Ricart): Kia Techline case [XXX] opened; CAN signal confirmed out of spec at a passenger kick panel connector; dash harness replaced per Techline under warranty (~$2,800). V5 (current): same warnings returned within days, confirmed by the dealership; vehicle is in the dealer's possession for continued diagnosis and available for inspection. Warnings first appeared June 2026 at ~58,500 miles, recurring since. Current mileage ~59,700. No crash or injury. Kia Consumer Affairs case open. Note: attached RO [XXX] says no issues found after repair — outdated; warnings returned within days, vehicle back at dealer. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

   When stopping for a traffic sign or light, the car announces that it is shifting into park and does so. The car then will not shift into drive or reverse and is essentially disabled. Turning off the car completely and turning it back on will not return it to "Ready to Drive" mode. Jump starting the car, provided it is jump started twice, will clear the problem and move the car to "Ready to Drive" mode. The car has been towed to dealers on three occasions with the technicians reporting they cannot reproduce the problem and no codes are being logged. On the third occasion, the dealer replaced the 12-volt battery. The failure occurred on the dealer's lot when I arrived to retrieve my car, but the technician reported that the problem went away and no codes were logged, so I should leave with my car. Subsequent to the battery replacement and including the failure on the dealer's lot, the problem has occurred 6 times in 7 days. Prior to the 12v battery replacement, the problem occurred once every 4 to six weeks. The problem has occurred a total of 9 times between April 25th and August 31st, 2026. This is an extremely dangerous problem as failures occur in traffic and require police assistance to safely tow or jump start the car. Should this failure occur during a left turn or on a highway, the outcome could be catastrophic. The car is available for inspection upon request. There are no warning lamps, messages or other symptoms of the problem prior to the failure other than the announcement that the parking brake is being automatically engaged. I have opened a case with KIA Customer Care.

   After sitting 2 weeks at airport parking. 12 volt Battery dead . Unsafe to repeatedly have to take out emergency key and pull handle cover off and get in car hit 12v button to start. The dealer we took it to refuses to replace the 12 volt integrated battery. It has happened multiple times. They checked battery and said it was okay. Repeated having to push 12 volt button unacceptable and unsafe.

   My 2023 Kia Niro Hybrid EX has experienced multiple warning messages and unresolved concerns after previous repairs. After the first recall repair, I began receiving intermittent warning messages while driving. The messages appeared briefly and disappeared before I could safely document them. After a second repair, the transmission was replaced. Shortly afterward, the vehicle displayed an overheating warning. I returned to the dealership, but they stated they could not find a problem. While traveling out of state, on July 6, 2026, the vehicle displayed warnings indicating that the 12V battery needed to be charged. On July 8, 2026, the vehicle would turn on, but the engine would not start or operate. Multiple attempts to jump-start the vehicle failed, including using a portable jump pack, another vehicle, and assistance from a tow truck driver. The vehicle displayed warnings stating that the 12V battery needed charging, the battery was draining, and that the hybrid system needed to be checked. Because the vehicle could not be operated and I was stranded away from home, I am concerned about the reliability and safety of the vehicle. The vehicle has undergone multiple repairs, including a transmission replacement, but I continue to experience warning messages and a loss of confidence in the vehicle's ability to operate reliably. I am requesting that this issue be reviewed for possible safety concerns.

   There's a problem with the horn in my car. Either the high or low. The problem is intermittent and the horn will fail and it is not available in emergency situations. I brought this to the dealership and made them aware but they refuse to take this seriously and two adequately evaluate the car. They blew the horn and said it was working. It was not working and I said it was intermittent and they said well we could not find any problem. There were no warning lights. Nothing else. The horn is just intermittently failing.

   The contact owns a 2023 Kia Niro. The contact stated that while her husband was driving at 40 MPH, the vehicle hydroplaned and pulled to the left unexpectedly. The contact initially contacted the dealer and was informed of the headlamp replacement and general inspection. Additionally, while the contact's husband was driving, the driver-side front tire experienced a blowout near a service station; the technician advised that the tire exhibited steel tread. An independent mechanic attempted a wheel alignment but discovered a rusted, bent tie rod, preventing the service. Following dealer instructions, the vehicle was towed to the dealer, where the wheels, both hub bearings, tie rods, and brake calipers were replaced. Despite the repairs, the owner refused to reclaim the vehicle due to the recurring mechanical defects. The manufacturer was not notified of the failure. The failure mileage was approximately 71,000.

   Car seat lower hip straps frayed on both sides. Had we been in an accident I have no doubt the strap would have ripped. I have 3 personal friends who checked their same Evenflo Revolve 350 car seat to find fraying in the exact same spots. And dozens of posts online with pictures showing the exact issues as well. The integrity of that straps in these seats are obviously compromised for so many people to be having them fray in the exact location. Evenflo is telling us all it's due to "external factors such as a mouse" but it would not all be the same car seat it happens to, in the exact same place on the seat, to people who drive their vehicles daily and have no other wings of rodents in their vehicle or issues with the other car seats installed in the vehicle.Baby/children's car seat safety is SO important and the strength of these straps needs investigated before someone is in a crash and their child's harness rips! Uploading my own personal photos-but I have many screenshots of pictures and posts from others having the same issue that I can provide upon request.

   The contact owns a 2023 Kia Niro. The contact stated that while driving at 25 MPH, the vehicle independently accelerated. The contact constantly depressed the brake pedal to stop the vehicle. The contact was able to coast the vehicle to the residence while depressing the brake pedal to prevent the unintended acceleration. Neither a dealer nor an independent mechanic was contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 11,000.

   I bought my Niro hybrid EX Touring new from the dealership in 2023. The first issue arose when the car shut off completely while driving and was towed to the dealership. Later, I started hearing a squeaking/rubber rubbing sound. The car would make squeaking and creaking noises when turning or going over minor bumps. The "rubber rubbing sound" happened when I was at a full stop, right after removing my foot from the brake, as the car began to move forward. These issues were both reported to the dealership, and they did an inspection. The dealership service center has been able to hear the sounds. Since then, the calliper boots have been replaced multiple times and the full calliper kit once. The strut bearing has also been replaced multiple times. Consistent issues with the car's braking system is a significant safety issue. I have no idea what damage the rest of my car could have sustained, and I have not been able to get an answer for why this is happening. I have also been in contact with the manufacturer.

    I am filing a complaint regarding my 2023 Kia Niro and Safety Recall SC332. The recall involves a damaged floor wiring assembly that may prevent proper airbag and seat belt deployment, creating a serious safety risk. I scheduled and brought my vehicle to Cowboy Kia, Conroe on Feb 2,2026 specifically to have this recall repaired, but the dealership did not complete the recall service and returned the vehicle without fixing the issue or providing a clear explanation. This is a manufacturer-issued safety recall and should be addressed promptly at no cost. I am requesting immediate repair and an explanation for the failure to perform the recall work.

    When attempting to activate the parking brake there is no response from the vehicle. No matter how many times in attempting to activate the parking brake it would not activate. The only way to successfully activate the parking brake was if "auto hold" was on and i turned off the vehicle. i have a safety concern regarding this matter as the vehicle could potentially roll away if the car is unattended. The problem has not been reproduced or confirmed by the service center as of yet but it will be inspected on 01/14/2026. There are no warning lamps, messages or other symptoms of the problem prior to the failure.

    USB connectivity is intermittent. This involves using the USB A connection in the center console as a port for stored media (music files) on a USB drive and Android Auto. The connection will connect and disconnect randomly regardless of the car being stationary or moving. The intermittent connectivity occurs regardless for all USB cables or thumb drives that I have tried. The vehicle is available for inspection. This presents a safety hazard due to the loss of connectivity for Android Auto while driving and the resultant sudden increase in driver distraction that is generated. Multiple steps and layers of infotainment screen navigation can be required to get to a workaround for music or navigation. The problem has been explained to the dealer service center multiple times but they are unable to replicate it and are explained that they are unaware of the issue on other similar vehicles. Video recordings of the intermittent functioning have been shown to the dealer. Since they could not replicate it, they are unwilling to correct the issue. The issue was first noticed in October 2024 and initially explained to the dealer service in February 2025.

    My car has clunking noises coming from the front left suspension, they occur more often and getting louder. After doing some research online, I found that the symptoms are similar to the NHTSA recall number 24V-057. Unfortunately, the NHTSA recall didn't include Niro plug-in hybrid manufactured in year 2023, only Niro EV. I took it to the service center nearby. They said it's the strut, so what they will do is to dismantle it and put more lubrication when I return again to perform a strut "maintenance". If there are still noises, then they will order a new replacement strut. However, from what I read online, it's actually the driveshaft that causes the problem, hence the recall 24V-057. Please investigate into Kia Niro 2023 plug-in hybrid vehicles having the same problems and issue new recall if possible. Thank you.

    I am experiencing the same issues as the individual who documented incident #11685147. When I turn the shifter to drive and let my foot off the brake, with auto-hold on, the will still roll backwards, even on flat ground, and not respond to me pushing the gas pedal. I have to put the vehicle back into park, and try again. Oftentimes I have to shut the vehicle completely off to be able to get the vehicle to respond to me shifting it to drive and accelerating forward. This occurs multiple times, but I have dated the incident to be the approximate time when this issue started.

    Driving VA Interstate 64. Traveling right side travel lane approximately 70 mph. Had ADAS engaged. Car entering highway, moved to center travel lane to pass. As I approached entering highway car, suddenly, my car stalled, engine off and I was stopped in center travel lane. Able to start car by putting transmission in park and pressing start button. Called KIA Car Care Center - They have no record of this type situation occurring throughout country. Took car to dealer. Their Technology Service Rep checked whole system and found no problems including memory bank listing the stall/stoppage incident. I will go to dealer and ask for their report. 2nd incident. Happened within first month or ownership 10/23. I dismissed incident as something I must have done due to my lack of familiarity with new technology.

    I was driving my 2023 Kia Niro PHEV into my garage after running an errand, going very slowly. Suddenly the vehicle--all on its own--surged forward, slammed into the rear wall (triggering air bags), ricocheted backward across the street, and struck a neighbor's fence. I was able to get out of the car but I was in shock; paramedics were called. Ultimately, my injuries were found to be limited to bruised ribs, but it has been very painful and limiting. The vehicle was towed to a repair shop where it was pronounced a total loss. I received a settlement check from my insurance company, but I am out-of-pocket for the deductible, costs relating to getting a new vehicle, and of course the pain and suffering. I was told there was an event data recorder (EDR) on the vehicle, and my insurance adjuster will tell me what it reveals (I hope). There was no warning of any kind that this was about to happen. I was fortunate that it happened where it did; had I been driving the vehicle on the street, I could have killed someone (including myself).

    This May of been a cause of a defective Harness Assembly that has taken a few tries to get repaired (Harness is fixed but problem still continues randomly). Since then, my car has stalling problems, randomly, sometimes multiple time in one drive. I have no way to replicate it on my own just that it "can happen" anytime and has subjected me to waiting on the side of the road for the engine computer to "reset" or needs for a tow. Ive been in the dealership at least twice for this with a 3rd this week. Me and the dealer thought it may go away with the new harness installed but it still remains
