Filed Sep 5, 2026 · Brakes, Electrical · OH

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 Note: attached RO [XXX] says no issues found after repair — outdated; warnings returned within days, vehicle back at dealer.

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.

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.

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.

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
