2019 Kia Niro. While driving normally on the street, the driver attempted to brake & the brakes would not respond. This is a very scary situation and Kia needs to handle immediately!! The message "Stop the Vehicle and Check Regenerative Brakes" was displayed. Thankfully the driver was able to come to a stop without crashing but if this was during heavy traffic time it definitely would've resulted in a crash. Could be even that much worse on the freeway, especially in Los Angeles. The vehicle was towed to the drivers home. After checking again, the vehicle was in limp mode & would not go over 15mph. The driver was able to get it to a Kia shop to be checked & they quoted a $9,000 repair!! This is horrible that Kia is allowing this issue to go on!!!

My car is a 2019 KIA Niro Hybrid. It's only 7 years old, and my husband and I have been the only owners. It only has 61,000 miles on it, and it is serviced regularly and has to pass a state emissions test each year. As I was driving the other day, the dashboard lit up with critical alerts saying "check regenerative battery" and the braking system went completely soft; I could not stop the car using the brakes. It was terrifying. I had to pull off the road and use the emergency brake to stop the car. This was an awful incident that could have resulted in deaths or serious injuries. Again this is for a car that is well-maintained and well under 100,000 miles.

Car has warning message and several engine lights on dash come up and asks to stop car and check the regenerative brake system. Car loses all systems that are electrical, car is very hard to drive, even not operative. This has happened many times over the past four years. Each time the car has been taken to a authorized KIA Dealership and they have not been able to fix the problem. It happened almost a week ago and dealership told us that they couldn't find anything wrong and were told to pick it up. Happened again today and it was while driving. Same issue, same warnings on dash.
