What owners say about the engine

Verbatim from NHTSA complaints, newest first
“2012 Kia Soul 1.6L GDI (VIN: [XXX]). Case #[XXX]. Safety Hazard Description: The vehicle experienced a sudden engine stalling event at highway speeds and repeatedly dropped into a restricted "Limp Mode" due to a recurring P1326 diagnostic code. This code is explicitly tied to Kia's Knock Sensor Detection System (KSDS) monitoring structural connecting rod bearing failure. The sudden loss of engine RPMs and throttle response created a severe traffic hazard, leaving me without power steering or predictable acceleration in active traffic. Dealer Information & System Non-Compliance: The vehicle is currently grounded and unsafe to drive. Southlake Kia (Merrillville, IN) verified that the vehicle's engine sensor and circuit are operating perfectly with an end-to-end wiring test reading at a flawless 0.2 OHMS (Repair Order #[XXX]). This mathematically confirms that the sensor is picking up real, severe internal mechanical vibrations from a failing engine block rather than an electrical short circuit. Official internal dealer records (R/O #[XXX]) prove that this severe engine defect initially manifested and was documented at 149,715 miles—strictly under the 150,000-mile…”

“On Oct. 14, 2025, this vehicle experienced a sudden catastrophic engine failure while driving approx. 70 mph on a highway. While in the passing lane, the vehicle began to lose power, shake, and wouldn’t accelerate. The check engine light came on just moments before a loud explosive noise came from the engine, and a burning smell came through the vents - the engine completely shut down. This failure occurred with other vehicles on the roadway, creating a serious safety risk. I was forced to quickly maneuver the disabled vehicle across multiple lanes of traffic to reach the right shoulder, where I called for roadside assistance. The vehicle was inoperable from that point forward, it would not turn on, and was towed from the scene. There were no warning signs prior to this event. The vehicle had been operating normally before the incident - I had recently checked the oil levels, there were no warning lights, no drivability issues, and no known mechanical problems before the sudden failure. This led me to find the vehicle was subject to an open safety recall addressing engine damage consistent with this failure; NHTSA Recall 19V120000. On Oct. 27th, the vehicle was…”

“On 12/ 22/ 2025 I went to start the 2012 KIA Soul and it would act like it would start but, it would not turn over. Battery was fine checked it. Let it set a moment and tried it again would not start. Called a wrecker and towed it in. The service guy tried and couldn't get it to start either. He ran a diagnostic on it, there were not type of codes, no check engine light nothing. He had it for until 1/5/2026 and when they went to check it it started right up. They drove it for 20 miles to check to see if it would cut off while driving, it didn't. It starts now but for how long. Here's the strange thing, I drove it 20 minutes away and I noticed that the counter for when You fill up with gas states how many miles you have left to go before fill up was counting UP not DOWN. So I think it could be the computer or electrical, I thought it was the fuel pump at first. Still no warning signals nothing.”
