I googled and a recall # SC200TE showed it was uncompleted. I called Holly Kia in Felton, Delaware, and they informed me my title is "branded" and therefore not covered under recalls. Then i google the recall again and now its gone.

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 recalls for this work. NHTSA SC351 seems very similar to this issue that has plagued this car since the beginning. We would ask that Kia incorporate this vehicle and others outside of the year/model ranges in SC351 that have similar failure mechanisms as this seems common.

XXX engine seized while driving on freeway — lost power, no crank, dash lights work, coasted to shoulder — safety hazard. Towed to Nayo's Auto [XXX] then to Kearny Mesa Kia [XXX]. Dealer confirmed 6 open recalls including recall 17V224 SC147 engine bearing failure / premature wear from machining defect. Kia corporate denied engine replacement under 15 year 150k extended warranty because product improvement PI1803 knock sensor update was not done. I never received PI1803 notification. I moved throughout [XXX] cities [[XXX] area] until moving to [XXX]. Kia mailed to old [XXX] addresses, forwarding expired, I never received at current address. All service since purchase was [XXX] not Kia dealer, so update never caught during service. I did not refuse update, I never knew about it. Vehicle is inside 15 year 150k miles and years, known manufacturing defect, not maintenance neglect. [XXX] maintenance on Carfax, DIY oil changes with receipts. Requested goodwill exception due to missed notification from moves — corporate denied via email, case on file. Request NHTSA review — safety defect, known recall, denied warranty due to missed notification from moves. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving at highway speed, my engine began to produce a loud knocking noise without prior warning. Within few seconds, the engine seized completely causing sudden loss of motive power.This caused a dangerous situation— loss of power steering and barking at highway speed, leaving me stranded in traffic lanes. I was forced to coast to the shoulder. The vehicle was towed to the nearest independent repair shop because it was not drivable and I was stranded far from home. The shop diagnosis —- seized engine due to big end connecting rod bearing seizure, identical to NHTSA Recall 17V-224 and KIA recall SC 17/ SC165 and TSB P1803 related to Theta engine bearing wear and engine seizure.My vehicle has the 2.4 L engine covered by this recall/defect.The failure occurred exactly as described in the recall: knocking , the seizure. KIA has denied warranty coverage because the vehicle was initially diagnosed and repaired at independent shop after the roadside emergency.The shop was used only because the vehicle was immobilized on the freeway away from home. I did attempt to contact a dealership in FortWorth, Texas, Morits KIA, but they could not provide roadside assistance or a tow solution at that time. I am reporting because: 1) This is a sudden loss of power at highway speed, which is a major safety risk 2) This appears to be the same defect KIA has recalled for, but the vehicle was not remedied or remedy failed 3) KIA is refusing to honor the extended warranty for this known defect I request NHTSA document this failure as part of the ongoing monitoring of Theta II engine failures. Vehicle is available for inspection and defective engine have been preserved.

My 2015 KIA optima experienced a catastrophic engine fire while I was driving. There was no warning, I just heard a boom in the engine bay the breaks stopped working and all electrical cut out. As I'm coasting, because I'm unable to stop, flames started to come in through under the dash. I couldn't turn the car off, nor put it in park so the doors stayed locked. The driver window was opened just enough for me to grab the top and break it, allowing me to crawl out. The car coasted itself to the shoulder then blew up (I had a full tank of gas.). All this happened in the manner of 30 to 35 seconds. It's important to note that KIA just replaced the engine 2 months prior to this incident.

Today as I was driving to work my car suddenly stopped while being idle at the stop light. It turned off. I was able to restart and drive to work safely and home. I googled the issue and saw many Kia optima owners having the same issues and they’re saying no codes or anything popping up. Should this be considered a recall.

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.

I was having trouble with my left driver tire. 2 mechanics went to test drive the car to see what the problem was. As they were driving, the car died. They got it started but it ran horrible back to the garage. When they pulled in the driveway of the garage, the car started on fire. It was an engine fire but undetermined what exactly was the cause. The vehicle was looked over by the insurance claims adjustor. I am not sure if sluggish driving had anything to do with the fire. The car is totaled.

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.

On July 14, 2026, the vehicle's engine was replaced by an authorized dealership under an official Kia recall. On August 16, 2026, while driving on the highway, heavy smoke suddenly began emitting from the engine compartment. When attempting to slow down, the braking system suffered a total loss of power and failed completely. To stop the vehicle, it had to be steered into the highway median to intentionally scrape against it to force a stop. Immediately upon exiting the vehicle, heavy flames were observed under the engine compartment before completely engulfing the front of the car. The fire department extinguished the fire, and the vehicle is a total loss.

The engine in my vehicle failed while putting the car into reverse to back into my garage. I thank God I wasn't on the road when this happened. I took the car into a mechanic who confirmed that the engine was locked and that the car was very low on oil(even though I had my oil changed by him a few months prior). There was an undetected oil leak that led to the engine failure. The warning indicators didn't appear on my dash until after my engine failed.

This is a formal vehicle safety complaint regarding a manufacturer's active refusal to remedy a known safety defect under an active recall campaign guidelines.My 2015 Kia Optima Turbo experienced an active internal mechanical engine knock, violent sputtering, and a complete engine seizure. The vehicle is currently sitting un-driveable at an authorized Kia dealership.The required Knock Sensor Detection System (KSDS) software update was successfully completed on this vehicle prior to the incident, legally qualifying it for a 100% free long-block engine replacement under the manufacturer's active Lifetime Warranty extension. However, the dealership service department is actively withholding the safety warranty paperwork and refusing to submit the diagnostic photos and engine seizure data to corporate for warranty approval unless I agree to pay an additional $800 out of pocket for an external throttle body and O2 sensor.I have explicitly declined the retail accessory charges five separate times. I only authorize the replacement of my front sway bar links. Instead of separating the ticket and processing the free engine block safety remedy, the dealer is holding my safety warranty hostage to force a retail sale. Furthermore, a manufacturer consumer care representative recently refused to listen to my request on this matter and dropped the call.The manufacturer is using internal technical advice to block a court-ordered safety remedy and is allowing a dealership to use unauthorized retail accessory charges to deny me a safe, operating vehicle. I request immediate federal intervention to force the manufacturer to release the free engine block safety replacement order to the dealer and halt these predatory dealer practices.
