2015 Kia Optima Cruise Control Problems

1st problem happened when I was at a complete stop, at a traffic light, in rush hour traffic. All the sudden steam started coming out from underneath my hood. I instantly looked at my temperature gauge and it did not show anything however I knew something was wrong when the light turned green I immediately pulled over, out of the street as far as I can get without being hit by other cars.

The contact stated that while driving at a slow speed while at a fuel station, the vehicle suddenly experienced unintended acceleration while the brake pedal was being pressed. During the failure, the RPM's suddenly increased although the accelerator pedal was not being depressed.

My kia started out making a strange squealing noise, then it started loosing power. When I stop at a light or stop sign I push the gas peddle and it takes awhile to get up to even 35 MPH. I was told the turbo manifold was bad so I had one put on.

Recurring, intermittent lack of engine response to pressing the accelerator; particularly noticeable when attempting to turn left at a break in oncoming traffic. Engine acts as if stalling, then recovers after a second or two delay. Kia dealer service advises that this is a characteristic of the vehicle and not adjustment is possible to fix the problem.

When driving on the highway my car suddenly started to stall with me on the highway. It went from 80 miles per hour to 20 miles per hour and then completely shut off in the lane of the highway. Thankfully I was able to pull over to safety.

Excessive shaking of engine, stalled out while driving on highway, knocking in the engine.

I was on the freeway and out of no where I couldn’t accelerate and immediately my car slowed down and I had to get over the car behind me had to slam on breaks and I was almost hit twice car then flashed to pull over and charge battery but it’s a brand new battery everything still turned on just couldn’t accelerate so it’s now towed to Kia dealership to get diagnostics done scariest driving moment ever

I was driving down the street came to a red light and when I tried to press the gas my wheels locked and the car wouldn't go. I had to push it down a hill and use neutral to get at least get the car off the main street and towed. The next day it was taken to kia and now they are telling me they can't help because I couldn't provide receipts of any maintenance that was done on the car over time.

I noticed that while driving my car it would first make a noise and then right after it would stall and sputter/ jerking like it wants to cut off.

Car would not drive faster than 25 MPH. Check engine light on codes p1326 and p0014. Not eligible for ki engine settlement but have the same issue..

The last recall that was fixed is occuring again . Car loosing power warning signal popping up Sometimes smells like matches after parked.

3 months prior to my car going into limp mode I had an incident where I was on the highway and had to come to a stop of major traffic and suddenly my car cut off out of nowhere. I got it to crank after putting it in park, but it was very scary being on the highway thank God it was traffic to where cars wasn't going so fast.

My check engine light came on Sunday January 23rd. Upon Contacting my local Kia Dealership, I was told that my vehicle has recall # SC212 at which time was advised to bring my vehicle into the Kia dealership for diagnosis.

I was driving home from work and I noticed my vehicle having a hard time picking up speed and soon after it was a noticeable knocking noise coming from the engine. The RPM and dashboard gauges were very sporadic. I parked the car and popped the hood to find that there was somehow absolutely no oil, but no current sign of leaking from underneath.

The car sped is faster than what the speedometer day. The car jerks when you are sitting idle. The oil light keep coming on when the oil stick show that's its oil in there.

On march 7th 2019, I was driving down the highway at approximately 60 miles an hour I felt a click, & my engine light my oil light and my battery light illuminated. My car did not shut off but gas was not able to flow into the engine therefore I was coasting down the highway. I was able to get off on to the exit ramp I pulled over to the side, then I was able to shut my car off.

My car had started acting weird about 5 months after I got it, I believe Jan 2020. Only had it till Jan 2021 and they said my engine Barrings broke and it was going to cost me 10000. I didn’t have it.
