Problems:
Engine knocking
Engine knocking in Hyundai Sonata vehicles, especially with the Theta-II engine, is a known issue. It is often caused by irregular combustion, which can be due to poor fuel quality, carbon buildup, or faulty components.
Oil consumption
Excessive oil consumption has been reported in some 2017 Hyundai Sonata models. This can be due to worn piston rings or valve seals, leading to decreased engine performance and potential engine damage.
Engine stalling
Some drivers have experienced unexpected engine stalling, which can be due to issues with the fuel delivery system, a faulty crankshaft position sensor, or problems with the engine control unit (ECU).
Timing chain problems
The Theta-II engine has been known to have issues with the timing chain tensioner, which can lead to improper timing chain operation, causing noise, reduced performance, and potential engine damage.
Fuel injector issues
Fuel injector clogging or failure can result in poor engine performance, misfires, and reduced fuel economy. This is particularly a concern in direct injection engines like the GDI used in the Sonata.
Knock sensor issues
Faulty knock sensors can lead to improper engine timing adjustments, resulting in knocking or pinging sounds and potential engine damage if not addressed.
Cooling system failures
Problems with the cooling system, such as a faulty thermostat or water pump, can lead to engine overheating, which can cause significant engine damage if not resolved promptly.
