2012 Kia Forte Engine Problems

Vehicle: 2012 Kia Forte Recall: NHTSA 23V-652 (Kia SC284) – HECU/ABS fuse recall My vehicle underwent this safety recall in 2025. The dealership replaced the HECU fuse. Immediately upon leaving the dealership after the recall repair, the same warning lights returned. I contacted the dealership immediately before fully leaving the area to report the issue. I also contacted Kia Corporate after the warning condition returned. Kia was aware the warning lights returned immediately after recall completion. I was advised if the vehicle later entered limp mode again, to contact Kia roadside assistance for towing support per prior guidance. The warning condition was not resolved by the recall repair. The brake warning light remained present, additional warning indicators later appeared, and the vehicle ultimately entered limp mode in January 2026, resulting in loss of reliable transportation and safety concerns. Due to this condition, I was forced to rely on a rental vehicle for an extended period at significant personal cost totaling several thousand dollars. I'm a single parent with a child requiring ongoing medical appointments, making reliable transportation essential. Kia only approved a limited "goodwill payment" of $191.40 for an earlier rental period, while refusing reimbursement for the substantially larger rental costs incurred after the recall failure and progression to limp mode. When the vehicle entered limp mode, I had to arrange towing because Kia assistance was not available as they closed out the recall. Kia is now requiring out-of-pocket diagnostic payment before determining whether the issue is related to Recall 23V-652, despite the warning condition returning immediately after recall repair and later progressing to limp mode consistent with the original failure symptoms. I am reporting a potentially ineffective recall remedy and unresolved recurrence of the safety condition addressed under Recall 23V-652.

While driving, the engine suddenly shut off without warning. The vehicle lost power in traffic, creating a safety risk. There were no warning signs before the failure. The oil level was properly maintained and oil changes were performed regularly. The dealership diagnosed the vehicle and stated that the engine needs to be replaced. The exact mechanical cause was not clearly explained to me.

Engine started screeching out of nowhere, sounded like something fell through, there was no warning of any kind, car was running seemingly fine prior to this, car was jolting and not going anymore and something also sounded as if it had popped, it started knocking and caught fire and was smoking, breaking down on the side of the road and has been in another state since this occurred just sitting at a hotel because we had to get a rental car. We did call Kia in Georgia to have this issue rectified as we had recently bought this vehicle and were unaware there was a recall on it, however we did some checking and the previous owner also let us know there is a recall for engine fire. I do have the papers for that. Kia advised us they would not be responsible, but Panama City fl Kia where we live were willing to look at that car prior to this incident and take care of the recall, the previous owner never went but now the car has caught fire whilst we were driving in it 7.5 hours away from our house out of town with our children in the car. We had to pull over off of the interstate because the car was on fire and get out on the side of the road and all of had to evacuate. I do believe that if we had been going any faster, we may have even became fatalities because the car locked up. It turned off actually as I was turning to to the exit and just coasted far enough to not be hit in the middle of the road. It was terrifying and we had to move fast and smoke was starting to come through, it started dropping oil everywhere just spilling out lv its almost like the entire underneath of the motor just dropped or something. I’m not quite sure but it was sudden and it has been absolutely miserable.

Back in July my car started jerking, stalling, and smoking. There was a recall 20v750 open for engine fires. The dealership check it out and said everything looked good. They installed a knock sensor related to the problem. Last week my car did it again leaving me stalled on the interstate at night. There is now a P1326 code for the knock sensor which confirms that there was a issue. However I'm being told that due to my mileage the warranty had expired and there isn't anything they can do.

Kia denied repair and replacement of components damaged by a known safety recall (Hydraulic Electronic Control Unit) on my 2012 Kia Forte Coupe, VIN# [XXX] . There was also a recall on the “Knock Sensor”, but I was unaware of the recall and paid for the repair out of pocket. Specifically, I was seeking repair or replacement of the starter and battery, as well as any other component that I wasn’t aware of, which was compromised as a direct result of the defective HECU system covered under the recall. They denied the repair because they said that the warranty was voided because the car had a salvage title, but the request to repair was not a warranty issue. The recall involves the HECU potentially causing electrical shorts and engine compartment fires, which can damage surrounding electrical components — including the battery and starter. These are not wear-and-tear items in this case, but parts affected by the consequences of a manufacturer-recognized safety defect. The internal electrical short circuit condition of the HECU fuse caused an overcurrent, which resulted in the wire from the solenoid cable of the starter burning and damaging the starter. As well as the wire of the negative battery terminal, which also resulted in the battery being damaged. I even left the battery and the starter on the floor of the car to show proof that these occurrences happened due to the defect of the HECU fused because when I purchased a new battery and starter the overcurrent of the HECU caused white smoke to appear and was about to catch fire and burn out the replacement parts as well. Kia has declined to perform these recall-related repairs, citing that the vehicle holds a salvage title, which was issued due to hail damage only. I respectfully contended that the cosmetic damage had no connection to the mechanical or electrical condition of the vehicle and in no way contributed to the failure of the battery or starter.

My vehicle is affected by NHTSA Recall Number 23V652000, I have taken my vehicle to Jim Ellis Kia of Kennesaw on several occasions, I believe 3 separate occasions to try and get this recall resolved. Each time I am told that the fix, a replacement fuse, is not being accepted by my vehicle. Each time they attempt to replace the fuse, the vehicle goes into anti-theft mode where the alarm goes off consistently. The dealership is unable to tell me why and states they can not complete the recall because of this. Initially, they tried to state the issue was that engine oil was seeping through into my engine harness and that I would need a new engine harness, sending me home with a quote for $3,000 to fix the issue. That same night I took my vehicle to an actual professional, who told me the dealership had no clue what they were talking about and that there was no oil in my engine harness. I returned to the dealership requesting that my vehicle only be looked at by the master technician, after the master tech reviewed the vehicle he agreed there was no oil in the engine harness and that that was a misdiagnosis. Absolutely absurd to think they can send a customer home with a $3k quote with no oversight before doing so. The master tech stated he could not figure out the incompatibility of my vehicle and the recall remedy, and stated I would have to pay $300 for them to do a full electrical review as a first step of troubleshooting. I can not believe that a massive corporation like Kia is sticking a customer with a MASSIVE fire hazard of a vehicle that is a result of their negligence and telling me that 'although we have a fix, for some reason the fix doesn't work for your car and you're going to have to pay us to figure out why.' This is absolutely unacceptable, I am a college student and while driving my only form of transportation, I constantly have to hope that I am not a victim of fatality at the hands of Kia.

Aug 1, 2017

After taking my 2012 Kia Forte EX to the dealership for the fire risk recall (recall number 23V652), the dealership replaced fuses as part of the recall. Despite this, major safety issues persisted: 1. Brake fluid leak – The leak was not resolved after the recall repair, and my brake pedal continues to go all the way to the floor, creating a critical safety hazard. 2. Brake warning light – The brake warning light remains on, indicating ongoing brake system issues. 3. Traction control warning light – A squiggly line symbol appeared, suggesting further malfunctions related to the vehicle’s stability control system. 4. Burning smell – Despite the dealership’s claim that the recall repair was completed, I still detect a burning smell from the vehicle, raising serious concerns about unresolved fire risks. When I contacted Kia Customer Care at +1-800-333-4542, I was informed that the brake issues and fluid leak were “unrelated to the recall,” and I was told that I would have to pay out-of-pocket for towing, diagnostics, and repairs—exactly as the dealership had also insisted. This response has left me in a vulnerable position, both financially and in terms of vehicle safety, as I am unable to cover these unexpected costs on my own. Additionally, I was forced to drive my car home with the brake pedal going to the floor, endangering my life and the safety of others on the road. The dealership delayed addressing these serious issues, rushed the repair, and failed to fully assess the depth of the recall symptoms. Their negligence, coupled with Kia’s refusal to take responsibility, has exacerbated the situation. Given the financial strain and the unsafe condition of my vehicle, I urgently request a loaner car until all issues related to the recall are thoroughly addressed, whether Kia wants to take responsibility for these problems or not. The vehicle is simply not safe to drive in its current state, and I should not be expected to bear the financial burden of fixing what appe

The car shut off (engine died) when I was driving and it wouldnt restart. The car was in perfect working condition, low miles & well taken care of, no lights on the dash or anything. I had it towed to 2 different mechanics (first was private, 2nd was a Kia dealership) - they both told me I needed a new engine or I needed part of the engine fixed and told me it didn't fall under any of the recalls. From what I've read I feel like it is a manufacturer's defect due to all of the recalls on this model/engine.

The engine started knocking just like all the other fortes and theta engines that blew up or gained the same knocking metal to metal noise. I have since found metal shavings in the oil which tells me that my engine is on its way out the door just like the rest that had this same problem. My engine needs to be recalled and replaced alongside the rest! Kia needs to own up to there engineering mistakes and install a new engine. My car should not be ignored on that recall seeing as it has the same engine as all the other fortes that were given new replacement engines. I refuse to be ignored on this matter and will not put forth my own money to fix something Kia is liable for. Kia is putting my life and others lives in danger. When will they take actions and responsibility for the rest of the Kia’s out there with the same engine symptom. I also haven’t got a recall for a knock sensor upgrade. I refuse to be without a vehicle because of Kia’s terrible engineering and poor production and assembly of these cars. I should not be experiencing an engine rod knock at 100k miles that has only become louder with time. I will be presenting the car to Kia for other recalls to be done and will be complaining about the other issues. Thousands of people have had to pay out of pocket to get a new motor. That’s on Kia to make things right with there customers for selling them a faulty product.

I own a 2012 Kia Forte . My engine started knocking, ticking sound. A mechanic used a mechanics stethoscope and the cylinder is collapsed, bad lifter. I always keep the oil changed regularly since the day I purchased. This is the same problem reported by thousands of Kia owners. I expect Kia to cover a new engine as I know a lawsuit was filed for the same year and model that I have and they covered the replacement of engines.
