Engine owner reports: Kia Sportage years in the records

The records describe a possible crash, fire, injury, or loss of control.

“My car went into limp mode on the high way due to a faulty knock sensor. my car decelerated rapidly, which could have put me and others around me at risk. I had to repair this problem on my own even though other cars similar to my make and model have had the same issue.”

The records describe a possible crash, fire, injury, or loss of control.

“The engine consumes a massive amount of oil to where I have to check my oil constantly and refill as often as weekly. This can pose a risk to myself and others due to the engine failing while I am driving. I am sure other issues can come from an engine running out of soil that I’m not aware of.”

The records describe a possible crash, fire, injury, or loss of control.

“After fueling, vehicle idled fine with no warning lights. Once pulling onto the highway and making highway speeds, the vehicle suddenly lost acceleration, and was stranded in the highway. We required the assistance of law enforcement to direct traffic. It was 10pm and the temperatures were 35 degree below zero with the windchill. The vehicle was towed to a Kia dealership, where they diagnosed loss of compression in the pistons. The dealership stated the engine had been burning/consuming oil and that the burnt valve caused the loss of compression and sudden breakdown. This vehicle uses the 2.4L Theta II GDI engine, which has a long history of engine failures, oil consumption complaints, stalling, and class-action litigation involving sudden engine failure and loss of power. Kia denied coverage by claiming only rod-bearing failures qualify for warranty extension, even though excessive oil consumption and compression loss appear closely related to the same broader engine defect pattern. Other owners have also reported 2017 Sportage excessive oil consumption leading to compression loss and engine failure. I believe this is a serious safety defect because the engine can fail suddenly while driving at highway speed, drivers may have little warning before loss of power, oil consumption may not trigger adequate warning before catastrophic failure. This creates crash risk, roadside hazard exposure, and potential fire risk.”
