Apr 30, 2026Lane Departure

I am submitting a safety complaint regarding the driver monitoring/driver assistance system in the 2025 Kia Carnival. The system repeatedly issues “take a break” or inattentive driver warnings during normal, attentive driving conditions. These alerts are overly sensitive, frequent, and intrusive. Rather than improving safety, the warnings are highly distracting. The visual and audible alerts demand attention at critical moments, pulling focus away from the road. This creates a counterproductive and potentially hazardous situation, especially in traffic or complex driving environments. There appears to be no reasonable way to adjust the sensitivity or disable these alerts without impacting other safety features. A driver assistance system should support the driver—not introduce additional distraction or frustration. I request that this issue be investigated, including the calibration, trigger thresholds, and user control options for the system. A redesign or update may be necessary to ensure the feature enhances safety instead of undermining it.

The main screen dashboard suddenly turned off while driving and will not come back. No odometer, turn signal, lane keeping, anything available.

The "consider taking a break" feature pops up every 5 minutes when I am driving and it is beyond distracting and leads me to believe I have something wrong with my vehicle. There is no way to turn it off. Please demand that Hyundai/Kia issue a software update so I can turn this off. Thnaks!

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2025 Kia Carnival Hybrid Hev verdict →
