In the 2004 Kia Optima 2.4, the ignition failure sensor is situated beneath the engine's plastic cover on the upper right side. If this sensor malfunctions, you'll experience clear issues. The primary one is the car's failure to start. Furthermore, you might observe stalling and rattling when the car is idling. The instrument cluster might flicker or even fail to function. Replacing the sensor will set you back around $150, and the cost doubles if you hire someone to install it. Ignoring this issue is not an option as a car that won't start is obviously useless.
