The rubber pad on the brake pedal came off almost causing me not to be able to stop effectively. What was left is a small steel pedal which sometimes is challenging to feel.

During driving or while parked, the vehicle will shut off power brakes, and display an error "Stop Vehicle and Check Regenrative Brakes". When the power brakes shut off, the brake pedal location and feedback change sharply and the responsiveness is severely impaired. This error can occur at any time, which is very dangerous especially at highway speeds or when coming to a stop. I have let an authorized Kia dealership inspect the car for 31 days and did not see the issue. I took the vehicle back, and it happens frequently, so I drove it in with the issue active again and they have had it for another 7 days so far after seeing the issue actively reported. The first occurrence occurred at approximately 18000 miles, about 2.75 years of operation on May 12, 2022. since then, it occurs about twice per week.

The contact owns a 2019 Kia Niro. The contact stated that while driving at 65 mph, the rear driver side tire blew out. In addition while taking the exit and depressing the brake pedal, the vehicle failed to stop. The contact was able to stop the vehicle by steering the vehicle to the side and into a parking lot.

My brakes failed as I tried to stop for a traffic light on a city street. There was a car already stopped at the light, which I bumped into. As I was depressing the brake pedal, it 'gave', and the car continued to move forward; I was unable to stop. Luckily, I had already slowed considerably prior to the brakes failing, so no one was hurt and there was minimal damage. The other driver left the scene without exchanging information, and no police report was filed. The Kia service technician was unable to find anything wrong with the vehicle: No codes showed up regarding any problems; nothing was in the online history report; no leaks or damaged brake components were observed; test driving failed to replicate the problem. Although he said I could pick it up, so far I haven't ' I won't drive it if the brakes are not reliable! the accident could've happened on the highway at high speeds; someone could've been gravely hurt or killed... I found an article online that described a recall of Kia optimas for what sounds like the precise problem: The 'software for forward collision warning (fcw) may prevent the automatic emergency braking (aeb) system from engaging as expected when fcw senses a potential collision with a stationary vehicle.' NHTSA campaign number: 19V539. Article at www.consumerreports.org/car-recalls-defects/Kia-optima-recalled-because-automatic-braking-could-fail/ when I brought this article to the technician's attention, I was told they couldn't do anything about it unless a recall specific to the Niro was issued. I then called the Kia customer service number in the article I found, and was told they would initiate an investigation; so far I haven't heard back from them.
