2012 Kia Sorento Engine Problems

I am filing this complaint regarding a sudden and unexpected engine failure in my 2012 Kia Sorento LX equipped with the 2.4L Theta II engine. Vehicle Information: Year: 2012 Make/Model: Kia Sorento LX Engine: 2.4L Theta II VIN: [XXX] While driving, my vehicle experienced a sudden engine failure and lost power, leaving the vehicle inoperable. This occurred without warning. The vehicle received routine maintenance, including regular oil changes, and the failure was not due to intentional neglect or misuse. I am concerned because this vehicle is equipped with the Kia Theta II 2.4L engine family, which has been associated with previous recalls, investigations, settlements, and numerous consumer complaints involving engine seizure, premature failure, stalling, and safety concerns. I understand my specific VIN may not currently fall within an active recall; however, my vehicle has experienced the same type of catastrophic engine failure reported by other Kia owners with similar engines. I am concerned that vehicles outside current recall VIN ranges may still be experiencing the same defect. An unexpected engine failure while driving creates a serious safety concern due to the potential for sudden loss of power and increased risk to occupants. I am requesting that NHTSA review whether additional 2012 Kia Sorento vehicles equipped with the 2.4L Theta II engine may be affected and whether Kia's current recall population adequately addresses the known engine failure concerns. I have also contacted Kia requesting that they review my vehicle, authorize a no-cost diagnostic evaluation, and determine whether the engine failure is related to known Theta II engine defects. [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The clock spring needs fixed no features including the horn is working in my airbag light is staying on. Also I now have a loud knock in my motor I understand this should fall under the extended 15 yr 150k warranty; 2012 Kia vehicles (specifically the Sorento) with V6 engines are covered under major safety recalls for engine failure and fire risks. The primary issue involves metal debris from manufacturing that can cause premature engine bearing wear, stalling, and fire. You should check your VIN on the NHTSA site or Kia's recall page to confirm, as these recalls are still active.

Engine warning lamp illuminated as the engine lost some power. Code was diagnosed as the knock sensor issue. Unit taken to mechanic to evaluate and diagnose. Repair shop notified us that based on the sensor, the engine could succumb to a failure at any time. Engine oil was flushed, cleaned, and replaced. Code was addressed currently. This is similar to the failures observed by other engines in this class, however, it does not appear this engine is part of the lifetime warranty or recall.

I had my mechanic come to my house to diagnose what has been going on and it is a recall on the motor. Along with my car throwing codes as well. I purchased the car from car max told them almost a year ago something was wrong with my car and they told me it was nothing it was a transmission issue. My father raised me to learn how to fix vehicles so o knew something was wrong. Now due to their negligence I am stranded with two small children.

Not sure if you can help me, we bought a 2012 Kia Sorrento in 2011. The motor blew up at 92,000 miles. There was a recall on it and the motor was replaced. They gave us lifetime warranty on the motor. The second motor blew up as we were driving it at on 100,000 miles on the that motor. Luckily we were not on the freeway at the time. We took it to Findlay motors in Las Vegas for a new motor under the warranty. They contacted the KIA corporate office in Irvine Ca and denied our warranty. We have put in over $8,000.00 in the last two years on new struts, serpentine belt, motor mounts, brakes and 60-90,000 mile check ups. All done by Jim Marsh KIA in Las Vegas. We have all the reciepts. They will not even talk to us. They have a service rep. Tony Thomas in Ca who did not even look at the Sorrento or check our service records deny the warranty. This vehicle has had several recalls, not just the motor. I took it in for all the other recalls. It was unsafe for us to drive it when it blew up and unsafe to drive now. I am a [XXX] Veteran and think they are just hoping I will go away. I am hoping since their was a recall on this that maybe your agency can help me. Or maybe put me in touch with an agency that can help me by making them fulfill their obligation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There is a recall on my vehicle. I received my first letter in May2024. I took it to dealership and they ran test but said they couldnt fix the recall bc Kia hasn't sent them the remedy so they sent us home. I called Kia customer service and they said when remedy is ready I'll get another letter. I just got that letter a few days ago and called dealership (Superior kia Orangeburg SC). They will fix recall but trying to charge me for testing again claiming it's because recall wasn't fixed last time I brought it in..this was not my fault and they sent me home saying they were unable to fix at the time. This is a recall and I'm not supposed to be charged. They refuse to fix recall unless I pay them.

On August 23rd 2024, I drove this vehicle all day. But, upon reaching our final destination (ER department entrance) smoke began rolling out from under the hood. Once getting out to inspection the vehicle someone hollered for a extinguisher. I turned to look at the vehicle and I could see underneath of the 2012 kia sorento had flames. My son was still in the car so my mother and I ran to get him out of his rear facing carseat and ran away from the vehicle. At this time the vehicle still had a fire that went out with extinguisher but quickly light back up. After this the whole are and car filled with smoke. Fire department was called and this took them awhile to fully extinguish the fire. This could have hurt myself, my child, and my mother. I lost alot of valuable things including my son's new carseat, my children's double stroller, a tablet, clothing, etc. I have called Kia as I found out there was a recall that kia has none about and started sending notices out November 14th 2023. My vehicle sat at a kia dealership from January to March 6th and if this recall was so drastic such as a car fire why was this not taken car of when my vehicle sat for 2 months. I have a call into Kia as of Monday August 26th 2024. I am still waiting for a rep to be assigned my claim and to speak to them. As of Today August 28th 2024 Noone has reached out to me.
