KIA Complaints

The contact owns a 2021 Kia Seltos. The contact stated that while driving at 45 mph the engine experienced a complete loss of automotive power, and no warning lights were illuminated. The vehicle was towed to a local dealer where it was diagnosed and the contact was advised that the engine was faulty and needed to be replaced. The contact associated the failure with NHTSA Campaign Number : 25V099000 (ENGINE AND ENGINE COOLING). The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 120,000.

The check engine light illuminated with diagnostic code P0018 (crankshaft/camshaft position correlation, Bank 2), first recorded on a scan XXX. The vehicle was taken to a franchised Kia dealership in [XXX] on XXX at 88,719 miles. The dealer performed an engine teardown and provided a written diagnosis on XXX: metal debris on the exhaust camshaft position sensor, damaged camshaft phasers, a sheared camshaft pin, and metal contamination throughout the engine. The dealer states the engine requires either a major timing-system repair or complete engine replacement. This failure mode can cause sudden loss of motive power while driving. There was no crash, no injury, and no fire. The engine remains disassembled at the dealership and is available for inspection upon request. The problem was confirmed by a franchised Kia dealer in writing. NHTSA previously examined loss of motive power in this 3.3L V6 engine family in PE23-019, which named 2015-2021 Kia Sedona vehicles with 3.3L engines as peer vehicles. Warning prior to failure: check engine light only. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2016 Kia Soul is a 2.0L Gasoline Direct Injection engine. 1 prior recall for Kia Souls have occurred, which is seemingly identical to my issue. Recall SC176 addresses Kia Souls with the 1.6L engine, and it just so happens my issue is the same. Kia also issued a response to knock issues with the Soul 2.0L MPI engine, the KSDS Campaign, where Kia rolled out the Knock Sensor Detection System software update (Campaign SC200) to monitor for connecting rod bearing. I have the GDI so this was not available to me. The catalytic converter is damaged from piston corrosion. The engine hasn't been properly powering the car to allow it to accelerate, nearing stall from stop, and when trying to upshifting. Power loss combines with a regular whistling noise, and occasional knock noise. Kia has been having similar issues with their varying Soul models. They have attempted to limit the scope of what fixes they'll provide, but clearly the scope was not broad enough. The first symptom of this issue occurred several months ago, at which point I made an appointment asap with Kia, the soonest of which was almost 2 months later.

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.

A P0741 warning light comes on and off leading driver to believe the problem is intermittent when in fact it is a torque converter failed. The intermittent nature of the warning light could lead drivers to believe the problem is not a safety issue, particularly on a SUV with only 105,000 miles. However, when a converter fails it is definitely a safety issue.

The contact owns a 2018 Kia Sportage. The contact stated that while driving approximately 45 MPH, the vehicle lost automotive power with the accelerator pedal depressed. The check engine warning light was illuminated. The vehicle was taken to a dealer where it was diagnosed and determined that the engine needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 64,813.

Occurred on 8/3/2026: 1. I parked my car in my driveway 2. My car is sitting in the driver door storage area and my phone with digital key is sitting on the front passenger seat. 3. Vehicle is turned off; I exit the vehicle and close the door. 4. My toddler is the back seat (not on the driver side), so i start to walk over to take her out. 5. In the meantime, the car locks itself. 6. I walk back to driver door and it is locked as well. This was serious and immediate issue as the ambient temperature was 92 degrees F and car at this point has no circulation. Luckily I was at home so was able to hurry and grab my second key from home to unlock the car. It all took about 5 min and by the time I was able to get her out, she was sweating.

My 2023 Kia Sportage EX Hybrid has experienced repeated engine-related failures since October 2022, requiring multiple dealer repairs. The safety issue escalated in 2026 when the vehicle experienced sudden loss of acceleration while driving on highways. In April/May 2026, the vehicle lost acceleration twice within approximately 10–15 minutes. Warning messages appeared, including Check Engine Light and "Check Hybrid System – Stop Safely." The accelerator became unresponsive, requiring the vehicle to be moved to the shoulder. The dealer diagnosed P0030 and P1120 and replaced the Bank 1 Sensor 1 oxygen sensor and valve cover assembly with manufacturer technical support involved. Several months later, another highway loss-of-acceleration event occurred. The vehicle would not respond to the accelerator, RPM remained around 1,000, and it had to be safely moved off the road. The dealer diagnosed P2138 and replaced the accelerator pedal assembly. The repeated unexpected loss of acceleration creates a serious safety risk. The root cause remains unknown despite multiple repairs.
