Car simply started for me after work this past Thursday @4 pm I dove down the street and for about 5 mins and had to turn around due to me leaving something at work. When I arrived back at work I parked and cut my car off as I normally do and when I returned to start it back up it never did. I have previously been having to add 5 quarts of oil frequently at least once or twice a month for the past 7 months since last year. Was told my car had an oil consumption problem by a previous mechanical shop last year. Noticed that these cars have recalls on them and that my car and year do fit the requirements. I do owned my car with the Title in hand. It’s NOT a salvaged title. I have a service appointment on the 24th of June next Tuesday at Kia of Gastonia located in Gastonia, NC. I have to get my car towed to this establishment on Monday or the morning of my appointment. I’m asking that this situation can be properly investigated and properly and honestly handled under KIA policy. My name is [XXX] my # is [XXX] thanks INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving ~40-45, mph and my car stopped on its own, a warning ️ came up in the dash regarding ABS and to stop and not drive, luckily no one ran into me and I was able to pull over. I called a service center and they told me I could bring it in and they would do a diagnostic. I turned the car off and back on, the message was gone and my husband came and followed me to the shop. They ran the history and it was a code for ABS, they reset it and I was on my way. Not long after, I started hearing what sounded like a woodpecker under the hood and loud, while the car was on, in route and off. I took it in and service center was unable to diagnose/duplicate the noise and was told I would have to leave it, however, due to not having another means of transportation, I was unable to leave it. Twice more it gave me the ABS dash warning with stop and do not drive. I took it in and was told it Brake booster/ABS was making a noise, however, I need to take it to Kia for further assessment, which is not for 11 more days. According to accounts read online, this is a common issue and is dangerous for a car to stop you while driving.

My engine went out on my 2012 Kia optima hybrid in 2022. I was not aware of a recall on the engines. We paid for repair. Can we get reimbursed? Also we are now having issues with the braking system and the abs light is coming on. I see that there is a recall on this. Can this get repaired? I uploaded receipt well bank statement showing purchase from Martin imports in the amount of $1391. And we were charged $700 to put motor in.

While in cruise control hitting the breaks resulted in the car not wanting to slow down or stop. Had to go off road inorder to not hit vehicles in front of me. I turned off ABS and this issue isn't there. I have no warnings for my ABS system and this doesn't happen often. However it's getting worse now this is the worse it has ever been.

I WAS DRIVING 60-70 MPH WHEN MY HYBRID SYSTEM ALERTED ME THAT MY BREAKS WERE AN ISSUE. I THEN TRIED TO SLOW AND COULD NOT. THE CAR SLOWED ITSELF AS A SAFTY PROCAUTION BUT I WAS IN 70 MPH TRAFFIC. NOT SAFE. IT WOULD NOT COMPLETELY STOP SO I WAS FORCED WITH THE OPTION OF HITTING A TREE TO MAKE IT STOP. KIA SAYS THAT IT MY BREAKS ELECTRICAL SYSTEM BUT THAT DOESN'T MAKE SINCE. I HAVE MY CAR WORKED ON REPEATEDLY TO AVOID THIS AND NOW LOOK? SOMETHING MALFUNCTIONED THAT SHOULDN'T HAVE.

VEHICLE'S ABS BRAKE ACTIVATE RANDOMLY ILLUMINATING THE ABS BRAKE SIGNAL ON DASHBOARD,WHILE IN MOTION AND WITHOUT TOUCHING THE BRAKES. THIS CAUSES THE VEHICLE TO DECELERATE AND HAS MADE THE VEHICLE COME TO A NEAR COMPLETE STOP. EVEN IF THE GAS PEDAL IS PRESSED TO ACCELERATE THE VEHICLE WILL NOT INCREASE SPEED, ONLY DECREASE. THE ISSUE HAPPENS 8/10 TIMES WHILE MAKING TURNS AND APPROX 5/10 WHILE DRIVING STRAIGHT ON FREEWAY . THIS ISSUE HAS BEEN OCCURRING FOR THE LAST 4 MONTHS. FOR EXAMPLE ON FRIDAY 10/11/19 THE ABS BRAKE SYSTEM ACTIVATED, CAUSING THE CAR TO COME TO A SUDDEN DECELERATION 12 TIMES WITHIN A 30 MILE DISTANCE. THE LOCAL DEALER STATES THERE IS NOTHING THEY CAN DO. VEHICLE JUST HIT 127,000 MILES. SECOND OWNER SINCE 32,000 MILES. REGULARLY SERVICED AND PROFESSIONAL MAINTENANCE.

WHILE DRIVING THE VEHICLE BEGAN TO DECELERATE (BRAKE) ON ITS OWN. WHEN I PRESSED ON THE GAS PEDAL THE CAR WOULD NOT ACCELERATE. I WAS ALMOST REAR ENDED WHEN I ATTEMPTED TO MERGE INTO TRAFFIC BECAUSE MY CAR IMMEDIATELY BEGAN TO DECELERATE WHILE PRESSING THE GAS PEDAL. IT HAPPENED ONCE AGAIN WHILE DRIVING ON THE INTERSTATE AT ABOUT 65 MPH AND WITHIN SECONDS DECELERATED TO ABOUT 40 MPH WITHOUT EVER PRESSING THE BRAKE PEDAL. THE BRAKE LIGHTS ARE ON EVEN WHEN THE CAR IS TURNED OFF. DUE TO THIS IT APPEARS MY "TRACTION CONTROL" WARNING INDICATOR BECOMES ILLUMINATED. I AM AWARE THAT A RECALL WAS ISSUED FOR THIS EXACT SAME THING BUT ONLY FOR THE 2012-2014 KIA FORTE (RECALL NUMBER 17V773000). THIS IS A MAJOR SAFETY ISSUE/HAZARD FOR WHICH THE RECALL NEEDS TO BE EXTENDED TO THE 2012 KIA OPTIMA AS WELL.

BRAKELIGHTS COME ON, EVEN WHEN CAR IS TURNED OFF. WHEN BRAKELIGHTS CAME ON DURING DRIVING, THE GAS PEDAL WOULD NOT WORK TO ACCELERATE THE CAR. BRAKE LIGHTS CAME ON WITHOUT EVER TOUCHING THE BRAKE. APPARENTLY THE KIA FORTE 2012-2014 HAS A RECALL FOR THIS EXACT ISSUE BUT NONE HAS BEEN ISSUED ON THE OPTIMA. THIS IS A SAFETY ISSUE BECAUSE THE CAR UNEXPECTEDLY LOSES ACCELERATION POWER. VERY DANGEROUS, SPECIALLY WHEN MERGING OR PASSING ON AN EXPRESSWAY.

2 DAY AGO I WAS DRIVING TO WORK ON THE FREEWAY AND MY CAR START ACTING WEIRD LIKE IT WANTED TO STOP, I PAID NO MIND. SO THEN THAT NIGHT COMING HOME FROM WORK IT START ACTING UP AGAIN, THIS TIME I SAW MY BRAKE LIGHTS TURN ON AND MY CAR STARTED SLOWING FIWN. I HAD LOST ACCELERATION I HAD NO RESPONSE TO THE GAS PEDAL. I WOULD STEP ON MY BRAKES THEN RELEASE AND THE LIGHTS WOULD GO BACK TO NORMAL. THIS HAPPENED THE WHOLE 45 MINS BACK HOME. SO THE NEXT MORNING I WAS DOING SOME RESEARCH ON WHAT COULD CAUSE THIS FOUND OUT THAT THE BRAKE SENSOR STOPPER WOULD NOT WORK PROPERLY ON THE KIA FORTE. BUT IT SEEMS THAT THIS HAPPEN TO THE KIA AS WELL. IT IS VERY DENGEROUS TRYING TO DRIVE LIKE THIS ESPECIALLY ON THE FREEWAY.

I HAVE A 2012 KIA OPTIMA HYBRID OF WHICH I PURCHASED AT THE LOCAL KIA DEALER (ONTARIO, CA) AND EVEN PURCHASED AN ADDITIONAL "PLATINUM 100K MILE PROTECTION." ON DECEMBER 31ST MY CAR STARTED TO MOVE WHILE IN PARK AND THE IGNITION ON. I HIT THE BREAKS AND THERE WAS NO BREAK PRESSURE AT ALL. THE CAR STARTED TO FLASH CODES REGARDING THE BRAKES AND I HAD TO ENGAGE THE EMERGENCY BREAK TO STOP THE VEHICLE. THE DEALER COULD NOT FIND THE ISSUE AND RETURNED THE CAR. ANOTHER MONTH LATER THE CAR DID THE SAME THING AND I VIDEO TAPED IT. THE GAUGES STARTED ILLUMINATING AND DELLUMINATING REPEATEDLY AND ALL THE LIGHTS ON THE DASH STARTED TO FLASH. THE "CHECK BRAKE" CODE CAME UP AGAIN! I NOW HAVE PROOF OF THE VEHICLE DOING THIS AND BROUGHT MY CAR BACK TO THE DEALER NOW THEY HAVE ADMITTED SOMETHING IS WRONG BUT THEY'RE STILL UNABLE TO DUPLICATE THE ERROR. THEY ARE KEEPING THE CAR FOR FURTHER DIAGNOSIS BUT HAVE NOT DONE ANYTHING BUT TELL ME THEY DO NOT KNOW WHAT IS WRONG WITH IT YET AND THAT MY WARRANTY "MAY NOT" COVER IT. THEY HAVE TOLD ME REPEATEDLY THAT THEY WILL NOT BE ABLE TO FIX IT OR DO ANYTHING FOR ME UNTIL THEY KNOW WHAT IS WRONG, NOR HAVE THEY OFFERED ME A RENTAL CAR. I WANT MY CAR BACK BUT IT IS UNSAFE! WHAT IF THE BRAKES GO OUT AT A HIGH RATE OF SPEED?! PLEASE HELP ME NHTSA SO WE CAN SAVE LIVES OF OTHERS THAT MAY EXPERIENCE THIS PROBLEM AS WELL. *TR
