“I am writing concerning the Driver Attention Warning system and how it seems to be way too sensitive and when it keeps going off, trying to see what is causing this issue. This seems to be creating more distractions than it is designed to solve. From my understanding Kia through a software update removed any sensitivity adjustments which makes this problematic.”

“The 2025 Kia Carnivals have a safety systems that prompts the driver to, Take and coffee break . The system cannot be turned off and is extremely distracting. The system prompts the driver even if the adaptive cruise control is turned off. I called Kia and they told me to take the vehicle to the dealer. The dealer was not able to turn the computer nag off either. The car makes a noise and the prompt flashes at the driver every few miles. This happens when traveling at highway speeds and in traffic. …”
