My 2023 Kia Niro Hybrid has a recurring intermittent electrical defect.

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.

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.

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.
