2015 KIA OPTIMA Service Brakes Problems

My 2015 Kia Optima has a failing ABS/HECU module consistent with the Kia ABS fire recall. The brake lights stay on constantly even when the brake pedal switch is unplugged. If I unplug the ABS/HECU module, the brake lights immediately turn off, which confirms the ABS module is back-feeding power into the brake light circuit. I also previously experienced the ABS pump running with the vehicle turned off. Currently the ABS, ESC, EPS, and Brake warning lights are illuminated and all stability/ABS functions are disabled. This is a clear safety hazard affecting braking, electrical safety, and vehicle fire risk. I have already been to the Kia dealer twice and they dismissed the issue after only checking the recall fuse. They refused to address the ABS module itself even though the vehicle is unsafe. The recall appears insufficient because the module has now failed. I need Kia to replace the ABS/HECU module under recall safety remedy.

What component or system failed or malfunctioned, and is it available for inspection upon request? The defects involve multiple electronic control systems, including steering, braking, and airbag modules, which continue to generate active and stored Diagnostic Trouble Codes (DTCs) even after the May 2, 2023 recall repair. The vehicle remains in our possession and is available for inspection upon request. 2. How was your safety or the safety of others put at risk? Because the vehicle fails to illuminate dashboard warnings, we were unaware of critical malfunctions occurring in real time while driving. This creates the risk of sudden failure in steering, braking, or airbag deployment, directly endangering both occupants and the public. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Independent diagnostic scans repeatedly confirmed active and stored DTCs following the recall repair. These findings show the defects are reproducible and ongoing. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was inspected by Kia’s authorized dealer, Spradley Motors in Pueblo, CO, for the recall repair. Since then, diagnostic evaluations have been performed by independent service providers. Documentation of these inspections is attached. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No dashboard warning lamps illuminated, even though faults were recorded internally by the vehicle’s control modules. The absence of warnings despite active codes is itself the central safety issue.

My motor bearing is knocking very loud I was refused service upon arrival dealer was making my service very complicated asking me to go dig up old receipts and various other things that was not actually caused for and I was at risk by driving the car there until it shut off due to engine failures when the car has fire risk and could possibly explode and they have confirmed it’s the engine but have not done any maintenance to my engine the check engine light flashes heavy non stop as well was even denied a loaner car still until today

I was driving on the Northbound side of the Interstate when my brakes failed when I pressed them to avoid a collision on the highway. The steering wheel malfunctioned when I tried to avoid a head-on collision with another vehicle. I couldn't control or stop the car, causing me to swerve left to right, and I then completely lost control of the vehicle. I crashed into the middle of the highway, but because my brakes had failed, the car continued at full speed into the Southbound side of the highway, causing me to wreck into a semi. The Colorado State Patrol investigated the accident. Right before I wrecked into the semi-trailer, I noticed all of the lights on the dashboard were off. My Steering wheel had fallen off completely, but the airbag never deployed even though every other airbag had deployed.

Engine fire

On May 11, 2024, we took our 2015 Kia Optima to Hutchinson Kia Service Center 3931 River Pl, Macon, Ga. due to brakes not working. When you apply brakes the vehicle would not stopped you would have to apply the emergency brakes for a complete stop. On that day, I was told no one was there to check my brakes due it was a Saturday and would need to schedule another appointment when they could do a brake diagnostic. The next appointment was June 4,2024, on that day we had the vehicle towed due to brakes. Today is September 2, 2024 and our vehicle is still there. On July 12, 2024, we were contacted staying vehicle was repaired and the problem wa a pin hole in the right brake line. We picked up the vehicle proceeded home at the first traffic stop same problem happen with the brakes.We returned immediately back to Kia Service center, explaining the same problem still exists. After vehicle being there for 2 more weeks, Nick with Kia Hutchinson Kia called stated there was a problem with ABS system and vehicle would be ready on August 21,2024. Well the still have my vehicle and no updates. When you call they put on hold and never comeback. If you go over the Service Manager is always out and no one can give you and update

While driving on freeway lights, flicker and car just dies. Steering goes out and lose control of vehicle. Then will randomly start up again

Driving down highway car engine shut off. Brakes are vacuum assist so brake pedal was hard and not very responsive while trying to stop car. Engine would not restart having to be towed. No warning lights, no strange noises. Just shut off. Engine possibly siezed. Looking in a kia forum this seems to be a recurring problem. I know there were Engine recalls in previous model years may need to be included for this year as well. Engine oil good, coolant level good.

The check oil and my fans stopped working and also my fuel pump and also my battery light went on

has failed or is unable to remedy this safety recall It smells like burning

- The issue occurred for the first time 4/30/2024 - The following 3 warning lights appeared while I was driving: ABS, Traction Control, and Brake - I took the vehicle immediately to a facility to have the warning codes read. The printout showed: C2402 & C2380 - The warning lights remain illuminated every time the vehicle is turned on - I believe there is a safety concern of a potential fire or brake failure

I've been having an issue with my car just out of the blue breaking while I'm going into it seems to be only a left turn I had let Kia know about this when I took it in for the other recalls just recently nobody seemed to have any idea of what was going on or look at me like I was crazy I guess and now I see this recall that explains everything to a tee of what my car is doing I need somebody to contact me please. This has almost gotten me into serious accidents on more than one occasion

Car stalled. Received check Brakes warning. ABS pump motor voltage fault message.

Coming to a stop and breaks go to floor u will freak out this happens in 2 different times

1. While stepping on the brakes my car has revved up as if I was pressing the gas. So I let my foot off the pedal and pressed the brakes again. This happened 2 times that week. And another time while I was coming to a stop light as I pressed the brakes, my car revved up but didn’t actually make my car speed up. I had to press the brakes again for it to stop. 2. My battery was smoking and I replaced it. 3. My car is consuming oil. The dealership did a series of oil consumption testing due to the exhaust leaving extra carbon residue on my car. They said it was fine but I don’t think they solved the issue.

My car started smoking while parked at work for no reason and I had to call the fire department. It stop smoking by the time the fire department came. I had it towed to the Dealer. My brakes are a mess but especially on a wet road you have to pump them to try to stop. I have taken it to the Dealer and of course they find nothing wrong. I told them to test drive it on a wet raining day and try to stop hard. Supposedly they could not but I have almost been it several accidents and had to run through a red light because I could not stop. So, I try to drive this car on a rainy day or drive slowly. This car has been trouble since I got it and the dealer will not listen.

My vehicle has 82000 miles and was due for new brakes. I an a retired former dealership technician so I decided to replace the brakes myself. When I removed the front brake calipers, I saw an unusual amount of rust of the steel caliper pistons. I've done thousands of "brake jobs" in my 30 years and I've never seen a caliper piston this bad. I plan on buying and replacing them soon. My concern is that these pistons look like they would rust completely through causing a failure of the brakes. This shouldn't happen on a 2015 MY vehicle or any vehicle.

As I was driving on the Interstate, my car lost power and I was unable to push on my gas or use my brakes to slow down to pull off the interstate. Lights begin flashing with a warning that read “ Check Hybrid system. Stop vehicle and turn off engine. This is the second time this has happened but before my car shut off and didn’t turn back on. I was going to be hit by a semi truck had he not swerved around. Also, this the 5th time this week it has happened.

I was in a accident in December where I went to brake at a light and hydra planed forward. Into the car I front of me.

Went to turn on my ac being a warm day and no cool air I called the collision center they then decide to tell me they are waiting on three parts still the ac compressor a part for the bumper and the turbo sensor. Meanwhile since it is a insurance claim I cannot have them check the recall part. So I made a appointment with Fred beans Kia in langhorne pa for the recall and a oil change they had the car all day to tell me that I need the part and it will be ordered that was April 23. Meanwhile Iam still driving with expired inspection. I then noticed my car started to shake and make loud sound when started and is feeling like Iam going to stall out and it does. It feel safe me being a single woman I don’t want to get stuck I called bot the the collision center and the dealership inquiring about the parts ordered and now my car is running horribly one pointed the finger at the other leaving me worried scared frustrated and upset.

I’ve completed the recall on Saturday it took them less then a few minutes even though the invoice said 0.00hrs. I showed that I had brake fluid leaking and the car smokes but was told to come back if things got worse. Saturday night I was driving to the house with my fiancée and the car started slowly if down, the check engine light came on. Then the car shut off in the middle of the highway after a while it just cut back on and smoke all the way to the house. If there was someone behind me I would have cause a accident but it not within my control. My car has randomly shut off while driving and a while later coming idling again, today making the 5th time with in 3days

I HAVE A 2015 KIA OPTIMA WITH 55K MILES ON IT. WITHOUT WARNING DRIVING TO WORK I SLOWED DOWN TO ENTER THE GATE AND HEARD MY BRAKES GRIND METAL ON METAL.

IT SEEMS OBVIOUS THAT MY CAR CAME FROM THE FACTORY THAT WAY BUT I HAVE NO PROOF.

EVER SINCE I PURCHASED MY KIA OPTIMA WITH ONLY 14K MILES ON IT PRE-OWN FROM THE DEALER... THE EMERGENCY BRAKE (PARKING BRAKE) HAS BEEN LOOSE AND IT HAS NOT BEEN WORKING CORRECTLY.

IT WORRIES ME THAT IF I EVER LOSE THE BREAKS THE EMERGENCY BREAKS WON'T STOP THE CAR.
