Brakes reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

I just recently purchased my 2019 Kia optima sx turbo. After purchase, I immediately began experiencing issues with the braking system and the forward collision warning light coming on. The cruise control stopped working as well. I googled and saw that there was a recall on the forward collision warning system but the local Kia dealership to me says there is not one. I almost had a head on collision in this car with my granddaughter coming from daycare as I completely lost brakes. I have put so much money into purchasing this car believing it to be a good car.

Lights appeared on the dash and the vehicle locked and would not drive. This happened as I was actively driving. I had the vehicle towed and was told by the Kia dealership that it was my abs/hecu. Before this happened, there was no warning lamps or messages. The car was driving normally.

Sometimes when I drive it will say my forward collision is blocked so it will disable but it normally shuts off. Tonight I'm driving on the freeway a steering wheel pops up then blind spot abs traction and a few more lights come on then it say check headlights those are dimming the radio is cutting off. The wipers aren't working but the car is still accelerating then all of a sudden the car goes from 55 to 0 the wheel locks and I have to coat to the side of the road.

The contact owns a 2019 Kia Optima. The contact stated while starting and driving at an undisclosed speed, the "Check Blind Spot Collision Warning System" and "Check Forward Collision Avoidance Assist System" messages became displayed. The ABS, traction control, and several other unknown warning lights were illuminated. The vehicle was taken to the dealer, who retrieved DTC codes: C121002 and C121102. The dealer replaced the rear wheel speed sensor. The manufacturer was not made aware of the failure. The failure mileage was approximately 20,000.

To begin, there was a recall on the forward avoidance collision system. The fix was to have the system reset at the dealership. Almost like a system update. I had that done after multiple lights appeared on my dash. 5 months later, the lights would illuminate again periodically, but turn off after a few minutes of driving. Two months ago, the lights came on when I was traveling on our highway at about 45 MPH. There was no cars in front of me, nor any objects. The automatic brake applied itself as I was turning off of this major highway. I hit the gas to try to turn off of the highway after the brake was applied, and my car wouldn’t accelerate. Since then, the light has stayed on every time I turn my car on, and for the remainder of the time I’m driving it. The brake has also self engaged itself twice since then. It’s a huge safety risk as someone could hit me from behind. The system update obviously didn’t fix the issues. The Kia dealership in my area, Tameron Kia, said that there was nothing they could do for me since they did the computer update. She was certain that it was a different issue, but it isn’t. My car has 60,000 miles on it and have been dealing with this specific issue since 3 months after I purchased the car. It’s not safe for my children and I, and something has got to be done about the issue.

ABS light came on for no apparent reason and took car to Kia dealership and was told it needs ABS Issue: “Your car is going to need an ABS Actuator, this controls how the ABS modulates the brakes when under dangerous braking conditions so that your brakes don't lock up..$2676.56 just for that repair if you'd like us to replace it” and I searched online and do see that some 2019 Kia models had a recall for this very issue, but my VIN is not showing up as affected. The lights came on about 6 mos ago, cleared and then came back on again. Car is at Moritz KIa in FW, TX right now.

I WAS DRIVING UP A HILL AND AS I REACHED THE TOP OF THE INCLINE, MY CAR STOPPED ACCELERATING. I THEN ATTEMPTED TO USE MY BRAKES AND I BARELY TAPPED THEM, BUT THEY REACTED AS IF I SLAMMED ON MY BREAKS. I TOOK MY FOOT OFF OF THE BRAKES AND I BEGAN ROLLING BACKWARDS EVEN THOUGH MY CAR WAS STILL IN DRIVE. MY BRAKES WERE THEN LOCKED, I PUT MY CAR IN PARK AND THEN TURNED OFF & THEN BACK ON MY CAR WITHOUT REMOVING THE KEY. I THEN PUT MY CAR BACK INTO DRIVE, HOWEVER, MY GAS PEDAL WAS STILL NOT WORKING. I THEN TURNED MY CAR OFF AGAIN, REMOVED THE KEY, PUT THE KEY BACK, THEN RESTARTED AND WENT BACK INTO DRIVE AND IT BEGAN TO WORK AGAIN. THERE WAS NOT AN ISSUE AFTER THAT.

THE BRAKES DID NOT ENGAGE WHEN APPLIED. THE ROAD WAS DRY. SPEED WAS 30 MPH OR LESS WHEN I ATTEMPTED TO STOP AT A LIGHT. THERE WERE NO CARS AHEAD OF ME, AND I HAD PLENTY OF TIME AND ROOM FOR A REGULAR STEADY DECELERATION. THE BRAKES DID NOT ENGAGE. JUST BEFORE I CROSSED INTO THE CROSSWALK THE CAR BEGAN TO BUCK AND THE BRAKE PEDAL FORCIBLY KICKED BACK EXACTLY FOUR TIMES, AND THE CAR FINALLY CAME TO A STOP. THIS HAPPENED ON A STATE HIGHWAY THAT ALSO SERVES AS A MAIN STREET RUNNING THROUGH DOWNTOWN. I WAS TRAVELING ON A STRAIGHT SECTION OF ROAD. I HAD THE CAR TOWED TO THE DEALERSHIP. I HAVE OWNED THE CAR, PURCHASED NEW, FOR 19 MONTHS. MILEAGE IS 17,325. THE DEALERSHIP CAN FIND NOTHING WRONG AND SAYS THE COMPUTER DIDN'T REGISTER THE EVENT. WE ASSUME THE BRAKES FAILED AND ANTILOCK BRAKES ENGAGED IN AN EXTRORDINARY MANNER. I HAVE NO DOCUMENTATION AS THE CAR IS STILL IN THE SHOP 37 ODD DAYS LATER. THEY STILL SAY THEY HAVE NO IDEA WHAT MALFUNCTIONED.

WHEN MY PHONE IS PLUGGED INTO THE CHARGER, MY SCREEN WILL GO BLACK ALL OF A SUDDEN, AND I HAVE TO TURN THE CAR OFF AND UNPLUG MY PHONE AND TURN THE CAR BACK ON FOR THE SCREEN TO COME BACK ON. ALSO, THERE HAVE BEEN SEVERAL OCCASIONS WHERE MY BRAKES LOCK UP ON ME, AND I ALMOST HIT THE PERSON IN FRONT OF ME. ESPECIALLY IN THE RAIN, AND I HAVE EVEN HAD TO SWERVE OFF THE ROAD TO AVOID A COLLISION. IT HAPPENS WHEN I AM IN MOTION DRIVING AND GO TO STOP. THE RADIO SCREEN THOUGH HAS TURNED OFF ON ME WHETHER I AM DRIVING OR IN PARK.
