RepairPal lists several issues with many Kia models, including a revised crankshaft pulley bolt, a faulty throttle position switch, malfunctioning door locks, and dim headlights. Additional problems among Kia cars commonly include the following.
1. Engine issues and failure
Noted on the 2011 Sorento and 2013 Optima, engine issues plague several other Kia nameplates, including the Kia Sedona, Sportage, and Forte. Problems occur when the engine shuts off without warning, if it can start at all. The engine can also knock or illuminate the check engine light.
2. Transmission defects
The Kia Sorento bears the brunt of this common problem. Outdated software within the transmission causes rough shifting and a jerking demeanor. Owners have also reported excessive noise from the transmission, but a simple update has often fixed the issue.
3. Excessive oil consumption
Owners of the 2013 Kia Optima noticed excessive oil consumption back in the day, but it seems the problem has reared its ugly head again with the brand’s latest model, the Kia Seltos. The 2021 Seltos also consumes oil excessively, which could lead to engine failure if left unchecked. Sometimes, no repairs can be done to fix this issue permanently.
4. Paint imperfections
Kia Rio, Sportage, Spectra, and Sorento models from various years suffer from bubbling and cracking paint. Most of these defects are common in harsher climates where the heat reaches well over 100 degrees Fahrenheit. However, it can easily affect the cosmetic appeal and resale value of these vehicles.
5. Airbag concerns
Outside of the Takata airbag recall that affected millions of vehicles, the airbag units in Kia cars tend to have problems. The control unit malfunctions somehow, causing the airbag to work improperly. Models affected include the 2009 Spectra, Sedonas from 2017 through 2019, and some Forte models.
