Hi my 2015 Kia Optima on 08/07/2020 I put the recommended gas in my tank and then got onto the interstate after about 5-15 mins it started loosing power and I could no longer accelerate past 60. Also now when I start driving it jerks really bad and won't go past 2 on the rpms. When it jerks I'm assuming that it is the gears trying to change. Also my check engine has acted weird ever since buying this car it comes and goes and just recently is when it stayed on and when this happened it began flashing when the loss of power and couldn't accelerate properly issue began

've had nothing but problems with my car, first with my break light switch, then my A/C control panel went out. Now. As I was waiting for my food in the drive through lane my car engine turned off but my car was still on, I was able to turn my car off and get my engine going again.I also have an issue where my engine won't start but my car will turn on also when stopped at stop lights I often feel my car jitter a little. I had my battery checked but that wasn't the problem. I will be taking my car to the dealership to see what the issue is.

8/27/2020 car had been at the Kia dealership 2 weeks before for the same issue...car shut down on the freeway after 'check hybrid charging system' lights flashing 'shut down engine' lights flashing. Kia had determined car just needed a 'hybrid battery update' fast forward...I was driving to visit my mother in Idaho, driving about 75 mph on the freeway, when the same thing happened: 'check hybrid charging system, shut off engine.' All the lights started flashing, and 'possible battery management system issue' diagnostic flashed on the radio screen. The car started losing power before locking up completely, wheel locking, shutting off and spinning out on the highway. Luckily another other cars were close by or else this would have easily turned into a fatal crash. 3 hours on the side of the road and a $450 tow into the nearest Kia dealership which was 2 hours away.. and I find out it's a blown hev fuse and the hybrid system/battery has failed completely. Now I'm stuck with a dead car. Failed at around 79,500 miles. This is not the first Kia Optima hybrid to do this!!! recall these cars before they kill somebody!! I should not have to worry about a 5 year old car shutting down and locking up on the freeway while driving. Especially with kids in the car. I will never buy another Kia again. It has the 10 year 100,000 mile warranty which Kia is saying covers no part of any repairs. Odd since this is a known issue with these hybrids!! recall these death traps!!!

I was driving home from work and my car stalled on me out of no where. I was able to get started. All my lights on my dash board came on and my car was making a bad rattling noise. I was able to drive it home, still stalling from time to time. I got it towed to a mechanic shop. He said it sounds like a bad engine and it sounds like it could blow. I've had my car for 2 years and have never had a problem with it. It never made a noises before or anything to indicate my engine was going out. I got my piles changed on 8/11/2020 around 2:30pm at murphysboro, il walmart. This incident happened on 8/13/2020.

I was driving down the street and my car started jerking, shaking and making noises. It was unsafe to drive home, so I pulled over and had the vehicle towed home.

While driving down the road and coming to a stop light I went to take off and lost all power. I brought my vehicle into the service facility where I bought it from and I was just told I need a new engine. I have a 2015 Kia Optima LX with 64,000 miles.

As I was traveling on the highway, I pulled up to a red light, when the light changed my vehicle would not accelerate and I there was an 18 wheeler coming up behind me with my 80-year-old grandmother in the car. Thank god I was able to get out of the way in time. I just bought this car with low miles and I have oil in it and out of nowhere there's it's loud ticking noise coming from the engine and somehow my oil is back low again. This so totally on Kia so many complaints not enough resolution.

The check engine light is on and the vehicle lacks acceleration. A loud tapping is coming from the engine. Thia started on July 25, 2020 while driving on the highway.

I was driving on the freeway and all of a sudden the check engine and all lights came on. I could not accelerate or stop the vehicle the brakes did not work I coasted off to the side of the freeway and hit the guard rail because I had no breaks. Then I had a tow truck come and pull me off the freeway to see if I could start my vehicle however it did not start all the lights were on the dash on and the car was smoking and smell like fire I had the car towed to the mechanic to find out what is wrong. The mechanic said the engine is fried because the oil pump was not being pumped into the motor therefore it locked up he said I believe there is a recall on this vehicle for the same reason I checked the recall and there is nothing in the system that a 2015 Kia Optima is up for recall. I believe Kia needs to refund this vehicle that has only 88,000 miles in the engine needs to be replaced Kia needs to call

I was driving on interstate 40 in Tennessee and my car just stopped running. I was in right lane and I pulled off to shoulder. A dot emergency repair truck stopped and tried to jump my car, but nothing happened, not even a noise or anything. Called aaa for a tow.

I was driving and out of nowhere the car started to bog down and the check engine light came on. It continued to do it every few seconds and was getting worse the whole way to the shop, which was the closest one I could find as soon as it started doing it. The shop ran the error code and got a knock sensor error. I had Kia come pick it up and take it to the shop. The shop performed a bearing clearance check and the vehicle did not pass so they replaced the engine and intake manifold due to "catastrophic failure". while replacing the engine they found the turbo had play and so they installed a new turbo assembly. After engine replacement they found the starter seized, they replaced the starter. After engine replacement they performed the ECU update and reset adaptive values, then performed wiring signal interference check which started ok. Immediately after getting the vehicle back from the shop I noticed a loud noise coming from front driver wheel area. Shop ended up replacing caliper and wheel bearings along with needing an alignment. All happened around 58K miles. Luckily still under warranty. Shop said it was just a bad engine. Nothing I could of done could of caused it.

I purchased a new 2015 Kia Optima. Completed regular maintanence on it, and the engine failed (locked up) at 138,000 miles. Later, I was advised the 2015 Kia Optima and other Kia's were found to have faulty engines. Kia did not offer assistance at the time, but are now offering assistance since I have traded the Kia with a locked motor. I have been given the run-around for weeks and today a "regional manger" called and offered zero assistance and basically told me the faulty motor was not their problem. When the motor locked up, I was passing a car on the highway. The Optima stalled while I was in on-coming traffic, and then the motor died. I was able to pull over safetly, and the car smelt like an electrical fire, it never started again.

The brake lights would not go off when I turned my car off. This ended up killing my battery. When I got the battery recharged it allowed the car to start without the brakes being pushed in. Also I noticed that the stopper had broken. This allowed the computer to think that the brakes were engaged even though the peddle wasn't pushed.

The contact owned a 2015 Kia Optima. The contact stated that while driving approximately over 40 mph, the vehicle suddenly stalled, there were no warning lights. The contact had the vehicle towed to the dealer langdale Kia (1508 N ashley St, valdosta, ga 31602; (229) 242-0715) who diagnosed that the engine failed and needed to be replaced.

While driving down the highway was traveling around 65 mph on dry street in the far left lane (fast lane), my car started making a sound like metal clicking and then car started smoking. My husband gets over to the side of road and the smoke goes from gray to black and when he lifted the hood up flames coming from rear and passenger side of engine! luckily someone pulled over and had fire extinguisher to put out fire. Fire and police both arrived on scene and reports made. Vehicle towed home; waiting to tow to dealer to find out cause of fire. Regular maintenance and upkeep on the vehicle and no lights or warnings just fire. Kia knows there is major problems with these engines and choose to only recall certain years when they basically know any vehicle between 2011 and 2018 can be affected. Don't know what the outcome will be but very upset that vehicle caught on fire and Kia states since it's over 100,000 miles there's nothing they can do.

- Morrow, GA, USA

My car engine light came on. I took care to dealership. Dealership kept car for 2 1/2 weeks and ultimately will not pay for repairs. No recall repairs have ever been done on my car since I have had it and I was not notified of any recalls. Recall is for high pressure fuel line and the documentation states it needs to be replaced in my car.
