Steering flexible coupling was a recall over 10 years ago, it was replaced. The steering wheel "sticks" and it's catching again and they will not do anything. I'm not happy that this is an ongoing problem and can be dangerous if it sticks at the wrong time!Owner report · Steering · Jul 2026

Electriconic braking moduel with "Check Brake" indication light and"Hybrid System Warning! and vehicle will come to a stop and warning flights will flash until you turn off the vehicle sit for 10-20 minutes. Brakes will not work and vehicle loses power. Battery has been replaced and large 140 fuse in trunk of vehicle and no improvement. KIA states no recall on my vehicle, but my vehicle has had to have recall repairs done on it regardless of not being listed on this site. I need to know what to do. Vehicle is reliable otherwise. Right now, its risky to drive.Owner report · Service Brakes · Apr 2026
Sudden engine failure while driving with no warning. Vehicle began jerking, shaking, and losing power. RPMs dropped unexpectedly and the engine stalled intermittently. Multiple misfire codes were present (cylinders 1, 3, and 4), and the engine was found to have low or no compression in cylinder 1. The condition rapidly worsened to near complete engine failure. The vehicle was operating normally prior to this incident. This failure is consistent with known Kia engine defects involving internal engine damage, including rod bearing failure. This is a safety concern due to sudden loss of power while driving.Owner report · Engine · Mar 2026
The car seized operating, shut down with zero warnings. It has been a reliable car and maintained. We towed to a mechanic who said it was engine failure. Thankfully we had just exited off highway and on a side street when it became inoperable or it would have been detrimental.Owner report · Engine · Feb 2026

When the brake pedal is pressed on the brakes will grab. It snatches the car kinda hard. Also when you give the car gas it will hesitate and will not accelerate. Another with the gas is that you can be driving at a higher speed such as 45 to 55 or so and you press down the gas pedal like your going into passing gear and it will not accelerate it's like it's trying to stop. Feels like the car is gonna fall on down onto itself and it loses power.Owner report · Vehicle Speed Control · Jan 2026
