Lights appeared on the dash and the vehicle locked and would not drive. This happened as I was actively driving. I had the vehicle towed and was told by the Kia dealership that it was my abs/hecu. Before this happened, there was no warning lamps or messages. The car was driving normally.

ENGINE
Mi Kia Optima 2018 con motor 2.4L GDI presenta consumo excesivo de aceite, un problema que he visto reportado por muchos otros propietarios del mismo modelo. En solo 700 millas recorridas, el aceite baja hasta el punto “Low” sin fugas visibles. Este consumo anormal puede causar fallos en el motor si no se revisa constantemente. El concesionario Kia ya revisó el vehículo, pero como no hay recall abierto, no ofrecieron solución, a pesar de que este motor ha sido identificado en boletines técnicos por este problema. Solicito que este caso sea considerado por la NHTSA para que se investigue si debe emitirse un recall extendido para los Kia Optima con motor 2.4L GDI.

ENGINE, SERVICE BRAKES, UNKNOWN OR OTHER
The car caught on fire while I was driving. No warning lights came on and the car didn't show it was running hot. I tried to engage the brakes, and they malfunctioned. I coasted the car to the side of the highway, where the fire and smoke plumed from under the car. I immediately exited the car and ran. As I was running from the car the grass was on fire. The car was totally destroyed by fire. The car has not been inspected by my insurance or Kia. Kia has a class action settlement for car fires the year, make, and model of mine.

FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM, POWER TRAIN
My 2015 Kia Optima Hybrid poses a serious safety risk. While driving at highway speeds, the car has randomly shut off multiple times. A "Check Hybrid System" or hybrid battery warning appears on the dashboard, and the vehicle either loses power entirely or switches to electric-only mode and coasts to a stop. This happens without warning, putting my life and the lives of others at risk. I already had the relevant hybrid system recall work completed by a Kia dealer, but the issue persists and the car remains unreliable and unsafe. This appears to be a known issue affecting many 2011–2016 Optima Hybrid vehicles. Kia needs to be held accountable for continuing hybrid system failures that occur post-recall and outside of warranty. This is a dangerous, recurring defect.

ENGINE, POWER TRAIN
Accelerating at a normal rate to get on the highway and the check engine light starts flashing out of nowhere and car goes into limp mode. Made it to local shop and they informed me it was a P1326 code and that a knock sensor would have to be replaced, but that Kia has recalled the older models for this same reason.

ENGINE
We are submitting this claim because the engine on the vehicle is completely locked up at only 50,000 miles, despite the maintenance being fully up to date. This issue appears to be directly related to the well-documented rod bearing failure that Kia has previously issued recalls for across various models and years. We have contacted several Kia dealerships in our area—including those in Anniston, Trussville, Huntsville, and even across state lines—seeking assistance. Unfortunately, all of them have refused to proceed with an engine replacement due to the vehicle having an older KSDS (Knock Sensor Detection System) software update. While we have documentation that the original update was completed within the required timeframe, they are now stating that a newer version of the software is required in order to move forward. However, when we reach out to Kia dealerships requesting this updated version, we are told that they cannot perform the update because the engine is already locked—placing us in a frustrating and seemingly impossible situation. We are essentially being told we need the update to fix the issue, but the update cannot be done because of the issue itself. We’ve also contacted Kia Corporate, and unfortunately, the response has not been helpful. We’ve been told that the recall campaign tied to this issue has closed, and that there is nothing more they are willing to do. Meanwhile, we are left with a vehicle that cannot be driven, despite only having 50k miles, and which we are still making payments on. This feels incredibly unfair and potentially unlawful, considering Kia has acknowledged bearing-related failures in similar vehicles. We are simply asking for accountability and support for a problem Kia is well aware of. We are at a complete standstill, with no cooperation from dealerships or corporate.

SERVICE BRAKES, HYDRAULIC
The contact owns a 2015 Kia Optima. The contact stated that the vehicle was previously included in NHTSA Campaign Number: 20V519000 (Service Brakes, Hydraulic) in October of 2020. The vehicle was taken to the dealer, who tested the vehicle to determine that the vehicle was not leaking brake fluid. Approximately 5 years later the ABS, traction control, and brake light illuminated, causing the vehicle to hesitate and jerk while driving. The contact stated that there was a burning oil odor coming from the vehicle. The contact inspected the vehicle and noticed the modulator valve was leaking oil, causing it to leak out of the vehicle when the cap was removed. The contact noticed oil on the skid plate underneath the oil pan. The vehicle was towed to the dealer, who diagnosed that the ABS module needed to be replaced. The vehicle was repaired. The manufacturer was informed of the failure and opened a case. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 87,600.

I was driving on the highway, the check engine light started flashing and the car lost power. This created a very dangerous situation because I could not go the speed limit and could not get off the highway since I was in the middle lane. We went and had the check engine light checked and were told the code was P1326.

ENGINE
My engine is burning oil at an alarming rate, my car is not recognizing low oil, so I no oil lights are appearing. I have to go to the oil change place weekly to have my oil checked. When my oil is low, I have to pay to have my oil replenished between months of my oil changes. My and my son safety was put at risk, when I found out at an oil change visit, I had less than an quart of oil I was driving around with. Which can cause engine failure while driving, overheating, and reduced performance while driving. This was confirmed by an oil change facility. I am currently in a ongoing dispute with the dealership I received my car from. The Kia dealership is refusing to do any maintenance until I can produce five years of oil change records that are not showing on car fax. To date my car oil light is not coming on, no signs are shown in my car showing this issue. I have to just get it checked weekly and pay for oil to be safe until, I can get a new engine.

Kia is aware of the engine oil consumption causing misfires, failed emissions test, blowing a rod and engine lock up. THEIR SOLUTION WAS A CLASS ACTION LAWSUIT THAT STATE ONCE THE CAR IS LOCKED UP OR ROD HAS BLOWN THROUGH THE ENGINE THEN THEY WILL FIX IT. I have had to replace the spark plugs multiple times in last 12 months due to misfires while driving. I HAVE BEEN TOLD BY THE DEALER THAT THEY CANT DOING ANYTHING TO HELP EVEN THOUGH THEY ARE AWARE THEY SUGGEST THAT I DRIVE WITH NO OIL AND LOCK THE ENGINE UP EVEN THOUGH IT COULD CAUSE A CRASH. MY LIFE SHOULD NOT BE PUT IN DANAGER FIRST IN ORDER FOR THEM.TO FIX THE ENGINE.
