I am submitting this complaint regarding the failure of the Kia Connect telematics system and the cessation of critical navigation support for my vehicle. Despite opening a formal support case with Kia (Ticket #25923650), the following issues remain unresolved: Loss of Trip History (Since January 2026): The Trip History feature within the Kia Connect suite has been completely non-functional since January 2026. This prevents the tracking of vehicle usage, mileage, and driving behavior data, which are core features of the paid subscription service. Failure of Connected Routing & Software Obsolescence: The "Connected Routing" feature is no longer operational. Kia support has stated this is due to the vehicle requiring a navigation update; however, Kia has ceased providing all navigation and software updates for this model as of April 2025. Safety Concern: The lack of software support and the failure of "Connected Routing" forces the vehicle to rely on navigation data that is nearly a year out of date. This creates a safety risk when the vehicle provides incorrect guidance on one-way streets, closed roads, or altered traffic patterns. Furthermore, the persistent failure of these telematics services raises serious concerns about the reliability of the vehicle's emergency communication systems, such as Automatic Collision Notification and the SOS Emergency Assistance button, which utilize the same underlying cellular module and software framework. Corrective Action Requested: I am seeking a mandatory software update from Kia that restores full functionality to the Kia Connect suite (specifically Trip History and Connected Routing) or a final navigation map update to ensure the vehicle’s guidance systems remain safe and accurate for the remainder of the service's lifecycle.

My 2022 Kia Carnival, approximately 80,000 miles, had intermittent dashboard warning lights and grinding brake noise for a few weeks. I brought the vehicle to Tasca Kia White Plains first time on 4/14/26 then again on 5/8/26. The dealership initially could not reproduce the issue, then later suspected an ABS sensor issue and ordered the part. On 5/12/26, before the repair was completed, I was driving downhill with my children in the vehicle when the brakes failed to respond properly. I had to steer off the roadway and go over rocks/boulders to stop the vehicle. At that time, the brakes would not respond normally, and I could not immediately shift the vehicle into Park. Police and towing services were involved. The dealership later replaced an ABS sensor. However, when I reviewed the codes with the service manager, I was told the ABS sensor code did not appear on the date of the brake incident. I was also told that an ABS sensor failure itself would not typically cause hydraulic brake failure. I am concerned that the sensor replacement does not explain the brake failure and that this may involve a brake/ABS/electronic stability control safety issue.

With very low miles on our Carnival, I had just left a stop sign and someone ran their stop sign at high speed and tboned my vehicle in the driver's side. I woke up from being unconscious while still in driver seat and my car was still limping down the road not far from the intersection. Pretty serious head, back and other injuries and was taken via ambulance to the hospital. The problem is that despite a high speed impact into the side of my vehicle, NOT ONE of the airbags deployed! I am confident that my injuries, that now seem permanent, would have been MUCH less if the airbags had deployed as designed. The car was totalled by Insurance. I do have pictures of it.
