2015 KIA OPTIMA Complaints

1. The O2 Sensor malfunctioned causing check engine light to come on. The Catalytic Converter failed or malfunctioned, an it is available for inspection upon request. 1wk after replacement of O2 Sensor installment, check engine light illuminated once again. [Official diagnosis was the catalytic converter was faulty but no mention of replacing 02 once catalytic converter was fixed]. 2. My safety as well as my children's safety was put at risk because there was and still is (even after repairs made from dealership where car was purchased) an issue with broken exhaust system and leak. A broken exhaust system poses extreme danger because it releases carbon monoxide (CO)- an odorless ,tasteless, highly toxic gas, which can travel in passenger area and cause carbon monoxide poisoning. Overexposure to this odorless and colorless gas can cause death. Even in mild cases of exposure to CO can cause headaches, dizziness, nausea and fatigue. I need not mention that the extreme or excessive temperatures caused severe discoloration where the three- way catalyst is located. The pistons could have melted as well could have caught the car on fire .My safety as well as every occupant that ever traveled in the vehicle thus far, was at risk. The exhaust leak was big enough to affect the oxygen levels, to spring that code. Another safety risk was when owner of car was falling asleep at wheel of car while driving, not knowing there's a leak. This put the owner and the vehicles occupants at risk which is the greatest threat by far. 3. The problem has been confirmed by Rivard Buick GMC. 4. The vehicle has NOT been physically inspected by the manufacturer or police but has been insoected by insurance representatives.

Engine locked up exactly like it is described in NHTSA ID Number 1147025. The manufacturer refuses to honor the civil suit judgement on this vehicle due to the previous owner and a Kia dealer not performing 1 recall.

My 2015 Kia was one of many Kias stolen from the Milwaukee, WI area. It was stolen from a secure residential parking garage by thieves who know they simply have to break a window to gain entrance to the car, break open the ignition lock, start the car with a USB port, and drive away. The police helped me recover the car and it is currently sitting idle at the shop for the past month waiting for a new ignition lock which is on backorder nationwide because of the high demand.

The contact owns a 2015 Kia Optima. The contact stated that while driving at an undisclosed speed, there was a knocking sound coming from the engine with the check engine warning light illuminated. The vehicle was towed to the dealer where it was diagnosed with engine code P1326 (Knock Sensor Detection System) and failed the bearing test. The dealer informed the contact that the engine needed to be replaced. The vehicle was not repaired and remained at the dealer.

Kia said they fixed recall on my car and lights are still on and I hydroplane and totaled my car

The morning of 3-1-2022, after driving for approximately 5 minutes, I noticed a ticking/knocking coming from the engine area. 10 minutes later, I stopped and opened the hood and it was definitely coming from the engine. This continued that evening when I went home. Sometimes it was quiet, but others times loud. I dropped it off at my mechanic the next morning, they later called saying it was an internal engine knock and they couldn't do anything with it. The next day I took it to another auto repair mechanic and was told the same thing, but they also said it needed a new motor, but to contact kia for any recalls. There are none for my 2015, but 2011-2014 DID have recalls and they were for the same problem I was having. I was given an appt for the following Tuesday, but by Friday afternoon the engine completely shut off while I was driving. Luckily, I was able to coast to a safe location. My check engine light NEVER came on for the 4 days I was having problems with it.

While driving on the highway, car suddenly lost power which was dangerous because there was no shoulder to pull over out of the way of other vehicles, & another car could have slammed into the back of mine, luckily was able to coast far enough exit highway. Had car towed to shop was told the engine had seized up. With no warning at all. Then I learned about the recall for this car, unfortunately a little too late in my case.
