Owner Complaints (6)

criticalSERVICE BRAKES,FORWARD COLLISION AVOIDANCE
CrashFiled: Mar 2026

Your 2021 Kia Soul's emergency braking and collision avoidance systems failed to activate during a near-collision, creating a serious safety risk. The vehicle is currently under recall and has been at the dealership for about a month. Kia has refused to investigate the braking system failure unless you pay out-of-pocket for data recorder removal and shipment. Fixing this issue will require the dealership to diagnose the brake system and collision avoidance electronics, likely involving replacement of faulty sensors or control modules.

criticalSERVICE BRAKES,FORWARD COLLISION AVOIDANCE
CrashFiled: Feb 2026

Your brake pedal failed to respond normally when you needed to stop suddenly after another vehicle merged into your path. At the same time, your Forward Collision-Avoidance Assist and Automatic Emergency Braking systems didn't alert you or activate to help prevent the collision. You had to steer sharply off the road to avoid a crash, which caused significant damage including a broken axle, damaged wheels, and broken brake pads. Diagnosing this issue will require the dealership to inspect why the brake system and collision-avoidance systems didn't function during the emergency.

criticalSERVICE BRAKES,FORWARD COLLISION AVOIDANCE
CrashFiled: Feb 2026

Your brake pedal failed to respond normally when you needed to stop suddenly after another vehicle merged into your path. Your Forward Collision-Avoidance system didn't alert you, and your Automatic Emergency Braking system didn't activate—both safety features that should have helped prevent or reduce the impact. You had to steer sharply to avoid a collision, which caused damage to your axle, rims, and brake components. The issue requires investigation into why your brakes and collision-avoidance systems didn't work as intended.

At my last six month servicing the service person neglected to notice my annual inspection was due. He did, however, tell me my brake pads needed replacing. I asked how that was possible since the car had less than 10,000 miles on it. He went to check with the manager after which he came back and said my brakes were fine. I got a ticket two weeks ago for not having a current inspection. I tried to contact the dealer a half dozen times via phone and their chat feature. They did not get back to me as promised. I scheduled an inspection at a local station and the mechanic noticed when he took my tires off for rotating that my brake pads measured 5.32 seconds. There was no apparent reason for this unusual wear and tear. I tried again to reach the dealer to ask why there would be excess wear on the pads and again heard nothing back. I contacted Kia of America but they would only take a report until I got a diagnosis from a certified dealer. I reminded the rep that there would be a record from my last servicing of 11/23 but was put off with repetitions of the script they use. I am concerned that there is an issue with the rear brake installation on this car that could lead to a dangerous condition for drivers.
