Multiple 2020 Kia Niro Hybrid and Plug‑In Hybrid vehicles are exhibiting identical Electronic Parking Brake (EPB) failures. I have personally encountered other Niro owners reporting the same intermittent EPB/ABS/ESC warnings. A Kia service coordinator confirmed another 2020 Niro currently in their shop with the same issue. In that case, Kia declined warranty coverage because the owner is the second…

The electronic parking brake controller failed after intermittent warnings that began while the vehicle was still under warranty. The parking brake actuator also failed and had to be replaced. The electronic parking brake system is part of the vehicle’s safety system, and the failure caused the parking brake to malfunction unpredictably. The issue did not store persistent diagnostic codes, making it difficult to diagnose earlier. This is a safety concern because it affects…

10.25" audio head unit. UVO no longer connects so that 911 and roadside assistance can not be reached. This is a known problem with 2019 and early 2020 Kia Niro's part# 96160-Q4210. I spoke to the Kia UVO Call Center and they confirmed that my unit is not communicating and has not since Dec. 2021. As I usually drive just around town I have not used UVO, but now that I'm on the road I need to be able to use this feature. I'm attaching a quote for a replacement unit
