While driving down the highway the cars Hybrid warning system came on causing the car to lose all breaks and lose power. The component of the vehicle that failed is the HECU. Kia already did a recall for this but did not include the hybrids for the recall. This is very unsafe losing all breaking power, driving 65 mph down the highway with my children in the car! There was absolutely no warning, no check engine lights nothing. I had it towed to the dealership and upon them driving it, it also cut completely out and did it to the person at the dealership. This is going to cause someone to lose their life and when you call Kia, it’s the same run around that your year wasn’t included in the recall yet there was a whole lawsuit about this.

Because the brake stopper or brake switch are messed up and my brake tail light stays on all night causing it to drain the battery If the car is braking while I’m driving it and the traction control light comes on and the speed is decreasing as I’m driving because the car is braking on it’s own it has nothing to do with the lights Nor the battery the root of the issue is the brake line because the tail light will not cut off because the brakes are still engaged even when the car is off causing the tail lights to stay on so the lights is what is draining the battery the lights stay on all night in a car the battery dies but the battery nor the lights is the issue it’s the brakes

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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2012 Kia Optima verdict →
