Known Issues for This Vehicle
Engine knocking
Engine knocking in the GDI Theta III engine can be caused by using low-quality fuel, incorrect ignition timing, or carbon deposits on the cylinder walls. This can lead to a decrease in performance and potential engine damage if not addressed.
Oil consumption
Some owners of the GDI Theta III engine have reported excessive oil consumption. This could be due to piston ring issues or valve seal problems, which can lead to engine wear and the need for more frequent oil changes.
