Not sure what the exact problem is and my mechanic cannot figure out either, I had the car a little over a year purchased from carvana! first few months the brakes started messing up got caught in the rain ran into a trash can left minor scartches but nothing was wrong internally. September got side swiped on the highway not a reportable accident but I had to change whatever held the wheel literally everything that holds the right wheel had to be changed and after that incident a sensor came off, traction with wheels off but still drivable, about 3 days ago the engine just started making a cracking sound mechanic said it was some sensors he changed both and still making the weird noise, only had the car for a year and my mechanic cannot pinpoint the problem and suspects some type of engine issue which idk if it’s a recall on kia Optima’s or not because I don’t drive crazy!.

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 with an SUV in front of me at 18-wheeler in front of them. This is on a road where the speed limit is 65 however there's a section on 301 where there's a traffic light. All three vehicles came to a slow normal stop and the adaptive cruise control was doing a good job of slowing the vehicle down without my input. But the SUV when we were at about stopping speed but had not yet come to a complete stop, the SUV switched to the left lane. At which point I was maybe 20 ft behind the 18-wheeler and all of a sudden the car is adaptive cruise control tried to accelerate the car back up to the setting of 65. It didn't register the 18-wheeler at all it just registered that the car in front of me had cleared the space and if I had not been paying attention and immediately applied the brakes to stop the car manually it absolutely would have accelerated directly into the back of the 18-wheeler. I was maybe 5 ft and it was still accelerating when I slammed on the brakes. I've been able to since reproduce the effects, it doesn't register 18 wheelers correctly in this specific situation as vehicles. I've even had the camera recalibrated in between tests. I have everything on video but unfortunately do not have access to the car's computer logs. I would be willing to send in my ecu for whatever is needed to identify this further.

On 6 June 2022 I was driving eastbound interstate 80 passing fairfield, CA. Traffic was moderate, average traffic speed 65. The kia’s adaptive cruise was enabled and set to the maximum amount of safe distance. I recall the car directly in front of me changed lanes to pass a truck towing a trailer. I remember the kia began to accelerate and I couldn’t turn the wheel. Next memory was opening my eyes to the dust smoke of deployed air bags. I lost consciousness likely due to the sudden impact and air bags deployed. I was taken to a fairfield hospital by ambulance where I spent 4 days. A slurry of tests ruled out loss of consciousness as the cause. No stroke, heart attack or seizure occurred. I was treated for bruised ribs due to the airbag. No doubt to me that this collision could have been catastrophic to this driver and others driving nearby. Witness reported that I sped up and clipped the truck/trailer while attempting to pass. What I believe happened: 1) the adaptive cruise accelerated when it determined there was room but failed to see the trailer and 2) the steering was unresponsive when I attempted to avoid a collision. The reaction time between car accelerating and getting knocked out had to be a mere three or four seconds. The vehicle was totaled, the insurance company, Mercury insurance, released the vehicle.

Suddenly, the warning lights on my dashboard resembled that of a christmas tree. I was seeing warning lights for the passenger airbag, blind spot warning/assist, auto-hold, adaptive cruise control, automatic emergency braking, lane departure warning, etc - were all suddenly offline. After finally getting an appointment scheduled with my local dealership, I was told that the airbag module had gone bad and needed replaced. With that module out, the car could not communicate with the other systems and thus was the cause of the errors/warning lights.

The contact owns a 2020 kia Optima. The contact stated that while driving at an undisclosed speed, the automatic braking system engaged without warning to stop the vehicle. Additionally, the cruise control failed to operate as needed and the vehicle intermittently failed to turn on while using the "push to start/stop" button. The vehicle was taken to the dealer and kia of cape coral (404 ne pine island rd, cape coral, FL 33909) however, both dealers could not duplicate the failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 7,500.

Cruise control does not maintain a steady speed and constantly fluctuates 10+- miles an hour! the dealer refuses to fix and says they cannot reproduce the symptom. I used a tracker and saw the dealer drive it around the block, never attempting to put it on the freeway.

I purchased a brand new 2016 kia Optima and have been experiencing a really bad rattling noise that is coming from the motor. I have taken my car back and forth from the kia dealership and each time they inspect my car, they tell me that they can’t hear any rattling. As a mentioned earlier, the rattling noise is still there. I have been to the kia in durham, north carolina and the cary, north carolina kia dealership and still nothing has been done. I believe that my head gaskets or something like that in the more was defects when I purchased my vehicle. I also feel that the kia dealership knew that my car had a defective motor and failed to inform me of that information. I would be glad to have my vehicle available for inspection upon request. How my safety and the safety of others are put at risk, is because the car could suddenly catch fire, it may stall in traffic, etc. The problem has not been reproduced or confirmed by a dealer or independent service center but I do know that something is wrong with my car and has been since I purchased it brand new in 2016. Kia motors did a quick look at my car and stated that they heard not rattling noises coming from the car. Other than that no other component been inspected by the manufacturer, police, insurance representatives or others? there are no warning lamps, messages or other symptoms of the problem prior to the problem and it occurred over 2 months after I purchased the kia Optima. If you are uncertain, simply state unknown, I am not sure as to why the vehicle rattles when taking off, but it is and have been loud enough for me to notice and my passengers as well. Therefore, I hope that this is something that you would look into and get some type of remediation. Thank you,.
