Vehicle was purchased in 2023. AC blower failure occurred for the first time in June 2024 and was repaired by PepBoys. On 4/2/2025 the ve3hicle had an active recall event when the engine seized on the highway because of a faulty oil pump/filter, Engine was replaced 4/17/2025 under that recall. Kia advised at the time that the wiring harness should be replaced due to electrical issues at the time but said that there was no recall for that work. At the time, there were no electrical failures of steering, brakes, all power etc. Nor did we know that those were a possibility. The wiring harness quote was $7,000, over the cost of the vehicle. It was decided to continue repairing the electrical issues as they came up, it was assumed that the fuses would blow before there because a safety or total vehicle failure, as automobiles are designed that way. 8/4/2026 the vehicle experienced a complete and total loss of power resulting in a traffic crash into another vehicle as the brakes felt like you were trying to push a wall rather than a pedal. There was minimal physical damage to the other car and the kia, the other driver got my husband's insurance information and then drove off. The car did startup after ~30 minutes or so and was driven home, but taken to the Kia dealership the next day. It was said that the blower motor overheated and melted a portion of the electrical junction box under the hood and that it was unsafe and dangerous to drive. Kia said that there were no active recal

While driving at highway speeds on the freeway in San Diego, the engine of my 2016 Kia Optima catastrophically seized without warning. I instantly lost all power steering, brake assist, and electrical power, creating an immediate life-threatening emergency. The vehicle was towed to a Kia dealer. Corporate Techline and the dealership are refusing to perform the mandated settlement rod bearing test and are falsifying paperwork to deny the safety remedy.

Blower motor is drawing excessive electricity, which in turn burns the fuse and junction pin, which in turn can start a fire in the car. Kia of Irvine suggested redoing all electrical wiring in the car, but that will not solve the issue. As soon as you turn on the AC, the blower motor will use so much electricity and amperage, so the blower motor fuse and junction pins on the fuse box starting to burn. Wanting to charge almost $7000 to fix this issue, which is double the price value of the car, and risking to end up in this situation again, as soon as you turn on the AC, does not make sense. KIA should do recall on this model and fix the root cause, which is excessive electricity and amperage usage by the blower motor.

Window falls into the door. The rear two windows have been repaired 3 times. They are currently both broken again along with the front drivers side. I currently have three windows being help up by tape. They are taped to the frame of the door to stop the window from falling into the door. I don't know why this wasn't a recall. I see there is a TSB BOD300. The dealership repaired once but never informed me about the known defect.

The engine assembly completely seized and the vehicle is currently stored at an independent repair shop . While traveling at high speed on Interstate 4 on July 24, 2026, the vehicle suffered a sudden, catastrophic loss of power and stalled in live traffic, creating an immediate threat of a high speed rear end collision. An independent service center officially confirmed the engine seizure after a dealership failed to perform an inspection during an eight hour wait, and no law enforcement or insurance inspections have occurred. Prior symptoms included severe, recurring oil loss requiring constant manual additions of oil between regular service intervals (most recently serviced in June 2026 at a kia dealership), and eventually the car completely shutoff on July24.

Engine failure, i was driving home from work and i went to accelerate from 0 to 20 miles and the car hesitated and didn't want to move. I took the car to the dealer three days later and it was confirmed that i needed a new engine. I was told by the dealership i was outside of my warranty but i just found out that i was covered up to 120k miles. No lights came on at the time and there wasn't any prior warnings to this happening. I had just put oil into the car two days earlier as i know in between oil changes that i have to put oil into the car and or check the oil to see if it is low.

NHTSA Bulletin TSB BOD300 My KIA 2016 Optima Turbo has all four windows impacted by the defective gear. I've opened a case with KIA and it's case number 25563361. None of my windows roll up or down. This presents several very serious safety issues. The dealer has had my vehicle for over 2 weeks. Why has KIA not been forced to issue a recall on these defective gears?

Code was on and off for a cylinder 2 misfire was off at this point (intermittent misfire) ecl was off car stalled out at 3rpms while driving, tiny puff of smoke once came from between the air intake and the engine, and also no crank no start but car has power. I’ve kept up with the oil changes every 3000 miles car had fluids in it and nothing looked bad all 4 spark plugs were burnt and i replaced them and still no success.

I had just stopped at stop sign and I turned right. My speed was approximately 40 mph and there was a LOUD POP. I immediately hit the brakes and had NO BRAKES. I got car off road and smoke was already coming from under hood. It caught fire immediately and burned up. Total loss . About 6 months prior to it burning I had a good bit of front end work done on it with bearing issues. Also put a new set of tires at same time . The coils and plugs were changed often because it would misfire. I purchased car July 2025. All my documents were burnt also .

The contact owns a 2016 Kia Optima. The contact stated that while driving 10 MPH, the front driver’s and passenger’s side windows lowered unintendedly. Neither the dealer nor an independent was contacted. The vehicle was not taken to the dealer or an independent mechanic to be diagnosed. The rear driver’s and passenger’s side windows were replaced, and the vehicle was repaired. The manufacturer was notified of the failure but offered no assistance since the VIN was not under recall. The failure mileage was 107,000.

The engine. I was at a stop sign when the car stop responding to me pressing the accelerator and would not go. Upon further inspection it was noted that my car had no oil in it. I am diligent in getting my oil changed every 3 months or 3,000 miles. My engine had "seized" and i am being advised to purchase a new engine or purchase a new car. While trying to get my car to acclerate i was almost hit 4 times in a matter of 10 mins.

My 2016 Kia Optima equipped with the 2.4L DOHC I4 GDI engine began to experience progressive and severe oil consumption during the latter part of my ownership. The oil warning light began activating repeatedly, even after shortly getting the oil changed. Several certified mechanics and oil change service stations told me this was an ongoing issue with this car and engine and that there was nothing I could do but monitor it and keep it filled. At their instruction, I monitored and had it changed more frequently, often topping it off at the oil change station and at home when needed. Approximately 2 weeks after an oil change upon putting the car in reverse it started to shake uncontrollably. The car was towed to a mechanic who stated I needed an engine. I then towed it to an authorized Kia franchise dealership where the technician documented the oil consumption complaint, confirmed a Cylinder 2 misfire code, performed a borescope inspection, and found the Cylinder 2 exhaust valve burnt with a chunk missing. Engine replacement was recommended by the Kia dealership technician. Prior to my purchase, the engine had already been replaced at approximately 80,000 miles under recall-related circumstances. The replacement engine installed by a Kia dealership subsequently failed, exhibiting symptoms consistent with the documented widespread defect affecting the 2.4L DOHC I4 GDI engine in 2016 Kia Optima vehicles, including severe oil consumption, cylinder misfire, and catastrophic intern

The car returned P1326 and had multiple misfires and audible knocking, the dealers will indeed fight the already existing class action warranties. Was sent home and told to “drive the fuck out of it”, to which the car did not make it home and blew gasoline into my cabin while driving on the highway. Almost passed out, and am still fighting Kia to actually address the defective rod bearings. I personally would fight tooth and nail over a 5 dollar problem, but this is something they do nationwide and can cause serious injury or death. If it weren’t a 200 LB man driving the gasoline shooting into the cabin would absolutely cause a knockout. To the time of this report they are still trying to disregard the rod bearing issue and send me home with fixes to problems caused consequentially.

The contact owned a 2016 KIA OPTIMA. The contact stated that while driving at 30 MPH occupied with her husband the contact heard a noise coming from the rear of the vehicle and smoke coming from the rear of the vehicle as you looked in the drive side rear view mirror and while depressing the brake pedal attempting to come to a complete at the traffic light, the brakes failed to work a intended. No warning light illuminated. The contact mention she kept trying to depress the brake pedal, however the vehicle kept accelerating causing the vehicle to crash into a ditch, go around a telephone poll, crashing into a rock garden which allowing the vehicle to come to a complete stop. The vehicle was towed to a towing lot call interstate towing then the vehicle was then towed by insurance company to a collision center. No injuries were sustained. No medical attention. The fire department extinguished the fire. The contact stated a police report was filed. The vehicle was destroyed. The manufacturer was not made aware of the failure. The approximate failure mileage was 166,834.

The Kia had a problem with the check engine light coming on and it gently went into limp mode. I had it repaired at Darlings Ford and it worked for about 600 miles. I had it repaired again and it worked for about 7,000 miles. The light recent came on and the car immediately hard banged andwent into limp mode. My wife was driving and shaking when she got home. The light went out and everything was fine. A couple of days later, on 5/27/26, we were on the interstate in traffic travelling 70 mph and it Violently hard bumped, the Cel came on and it went into limp mode. It was as if we hit deep pot holes with both front tires which we didn't as we were on a smooth highway. The light is still on and it's in limp mode.

This vehicle is eligible for Theta II class action settlement, and I cannot seem to get the Kia dealerships, or the Kia Corporate to honor the engine failure issue that I was told by the AAA mechanic should have been replaced. I have also been told by others, including another mechanic at a nationally recognized mechanic that it needs to be taken care of, and that they had the same vehicle and had there's taken care of without any issues.

While accelerating onto the highway in my 2016 Kia Optima 2.4L, the vehicle suddenly lost all engine power without warning. The vehicle would no longer accelerate and I was forced to coast and brake to safety. Immediately after the engine shut off, the check engine light, oil light, and battery light illuminated on the dashboard. After the incident, the vehicle would not restart or crank at all. The electrical systems, dashboard lights, and chimes still function normally, and the battery is new. The vehicle had proper oil level at the time of failure. No warning signs were present prior to the sudden loss of power. This failure created a serious safety hazard because it occurred during highway acceleration and left the vehicle unable to maintain speed or move out of traffic safely. Based on the symptoms and sudden engine shutdown, I am concerned this may be related to the known Theta II engine issues associated with Kia Optima vehicles.

The contact owns a 2016 Kia Optima. The contact stated that while operating the vehicle a knocking and rattling noise coming from the engine and the check engine light had remained illuminated. The vehicle was towed to the local dealer who informed that the engine had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure but no assistance was offered. The failure mileage was 150,000.

UNKNOWN THE AIRBAGS DIDN'T DEPLOY WHEN THE CAR HIT OTHER DRIVER FROM BEHIND.

Issue 1: High oil consumption in the engine due to poor engine design, according to the auto repair center. 5 quarts of oil are added to the engine once every 2-3 weeks. All oil leaks were previously repaired, but oil is still burning off. Issue 2: The engine has misfired more than once, with a puff of smoke coming out of the exhaust. Issue 3: Twice in the past 1.5-2 years, multiple spark plugs have failed, causing a breakdown. This is a Theta II engine, but it is not in the class action settlement.
