2015 Kia Forte: engine knocking or ticking

Filed Sep 30, 2026 · Engine · WA

Vehicle has developed a severe knocking during acceleration, that stops during deceleration, and returns when in idle. I'm sure it is poison slap. I know there is an extension warranty, but the dealer says my car doesn't qualify. Then the federal safety agency has the SC200 safety recall. I need help with this car. My engine is failing. Can you help me?

respectfully submit this correspondence to request formal assistance regarding my 2015 Kia Forte EX, a vehicle covered under the class settlement. The vehicle is exhibiting severe symptoms consistent with KSDS‑related engine failure, yet the required diagnostic protocol has not been completed by the servicing dealership. The KSDS software update was performed in May 2022, and the vehicle currently has only 92,000 miles on the odometer, placing it well within the settlement’s mileage parameters. Despite this, the dealership has failed to follow KSDS procedures and has not produced any written documentation of its findings. All communication with the dealership has occurred exclusively by telephone. Despite repeated attempts to obtain information, I have not received a diagnostic sheet, video recording, code report, KSDS documentation, or any written summary of the vehicle’s condition. All statements provided to me have been verbal and inconsistent. My **primary symptoms** include: - Persistent and worsening **engine ticking** - **Burning excessive amounts of oil** - Activation of **limp mode** - A **flashing check engine light** These symptoms align with known indicators of KSDS‑related engine failure and warrant immediate and proper diagnostic evaluation under the settlement terms. The dealership has verbally stated that the issue may be related to **spark plugs and ignition coils**. However, plugs and coils are a **well‑documented secondary symptom** of rod bearing failure, caused by oil contamination and misfires resulting from internal engine damage. This further supports the likelihood of KSDS‑related engine failure. Kia corporate has not referenced documentation of any kind. They have not requested it, indicated they are awaiting it, or provided guidance regarding its submission. Instead, corporate has repeatedly stated that they “must defer to the dealership,” despite the dealership’s failure to perform or submit the required KSDS diagnostic materials.

Vehicle started making a ticking noise under the hood. I immediately had it towed to a mechanics shop in town. They performed an inspection and said the ticking noise is from a Rod Bearing # 3 has come loose and the whole engine must be replaced. The car has only 108,000 miles. There were no check engine lights that came on either. I called Kia to see about getting a replacement engine from them and they informed me they no longer make that engine for that car anymore which is the 1.6 Liter Turbo Charged GDI 4 Cylinder Engine.

I purchased my 2015 Kia Forte5 in May 2024 with just over 50,000 miles. In 2025, I began smelling burning through the air vents while accelerating. I took it to a Kia dealership, paid a $173 diagnostic fee, and was told they completed the KSDS (Knock Sensor Detection System) recall update, but I did not need an engine replacement because “everything looked fine.” They gave me no clear explanation for the burning smell. When I called back and told them the smell hadn’t stopped, they said, “That’s just your oil burning — that’s normal!” and then hung up on me. I contacted 1-800-KIA, and my case was assigned to a woman named Tina. I explained that the dealership didn’t perform a thorough inspection and dismissed a very real concern. Tina sided with the dealership immediately and showed zero care for the danger I described. What Kia called “fine” has now made my car unsafe to drive. The smell has persisted, worsening, and is clearly a fire hazard. This model is under Recall SC200 for engine compartment fire risk, and yet they marked the recall “complete” — just by running a software update. No mechanical inspection or repair was done. After researching the federal safety agency complaints, I found multiple reports from other Forte5 owners who described this exact burning smell shortly before experiencing complete engine failure or fires. After the KSDS update, Kia advertised a 10-year/150,000-mile warranty for engines. But my vehicle doesn’t hit 10 years until January 2026, and it feels like they’re intentionally dragging this out to avoid honoring the warranty. I reported the issue months in advance, and I believe they’re delaying on purpose so I’ll age out of eligibility while the danger keeps growing. Kia is putting people in danger by closing out recalls without resolving the actual mechanical issues. This really needs urgent investigation and fast. I do not feel safe in this vehicle at all and and it’s stressing me out so much.

These included loss of power, rough idle, and a check engine light (CEL) which triggered the P1326 code confirmed by both a pre-scan and Kia dealership. System that failed: The engine and powertrain system. Issue stems from rod bearing wear as identified in Kia’s engine class-action settlement. Vehicle is available for inspection upon request.
