2012 Kia Optima driver assistance problems

Filed Apr 30, 2023 · Acceleration, Driver assistance · TX

Here I explain the problem better, when the car is at a low speed, such as when parking, the gasoline engine starts and it starts to rev up to 6k RPM and after that it brakes and hits hard, this would be dangerous on the highway and another problem is that when accelerating it has a delay of 1-3 seconds, and I want to report this problem to see if there is any solution

I was driving on the road at 40mph when the engine just stopped. There was no noise and the vehicle lost control. I was able to avoid any serious body damage. All the electrical accessories would turn on but the engine stayed dead when I turned the car on. After leaving it over night parked on a residential street the next day same situation all electrical devices turned on but the engine wouldnt turn on. I had to get it towed to the dealer I bought it from in order for them to take a look at what could of gone wrong.

Issue started 2 months ago. Noticed that vehicle acceleration is sluggish. Sometimes I have to take foot off the acceleration pedal then depress it again in order for vehicle to accelerate. Acceleration is unreliable and dangerous. Electronic stability sensor also started lighting up and cruise control became inoperable. Also noticed that my tail lights lit up on its own (and did not turn off) while vehicle is parked and fob not near vehicle, draining the battery. Police came by in the middle of the night to report that my tail lights were on. Tail light did not turn off when pressing the fob unlock/lock button. Had to restart the engine, drive around the block then turn off engine before the tail lights came off... But it turned back on again on its own that same night (in the middle of the night) and had to repeat the process. My battery was drained and had to replace it 3 days ago. I thought it was a battery problem (and was informed by dealer that it was probably a battery related issue) but problem persisted. Read reviews and this seems to be a running complaint with issues on brake pedal stopper or brake sensor stopper. Will bring vehicle to dealer in the morning.

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 happened on 11/08/2019 in the evening, I immediately took my vehicle back to kia and they claimed to have driven my car for 20 miles and didn't see or experience any issues. My car is a 2012 and only has 58, 388 miles. I demanded they keep looking but they caught an attitude like I made the scenario up and any stated that I should drive the car with their mechanic as they "cannot replicate my driving", like I'm driving in the [xxx] indy 500. Since it is now sunday, and the dealer is closed it will be sitting in their service center monday morning!

Brake light switch malfunctioning. Brake light on all the time rendering cruise control and electronic stability control inoperable. Loss of power in engine as it thinks brakes are applied making it dangerous to drive. Root cause is brake pedal stopper (kia part 32876-36000) developing a puncture hole over time making the brake switch believe brakes are applied. Known issue on other kia models. Believe the sorento already have a recall for something very similar.

My electronic stability control light on dash came on and remains on. I took to martin kia in newark delaware for diagnostic and they said the codes were c1259 and c1260 and that I need to have clock spring assembly, steering angle sensor and the steering column assembly replaced because it looked like my car had been in an accident. (I did strike a small deer, but damage was cosmetic to left front fender and did not affect steering or drivability, and was repaired in a professional body shop). The ESC did not come on until months after my accident. Dealer would not certify that the vehicle is safe to drive with this condition, nor did they offer another less expensive repair such as just replacing sensors. They wanted an estimated $1370 to hold my safety hostage. Since the light has been on, I have experienced a few episodes of instability when driving in inclement weather. I now leave ESC off when weather is bad.
