What's malfunctioning: coolant monitoring system shows low coolant warning when coolant level is observably fine. Problem has been ongoing for over a year. Available for inspection: yes. Safety problem: coolant monitoring is inaccurate, causing alarm when coolant levels are fine and possibly causing no alarm when coolant levels are too low. Problem reproduced: yes, by both dealer and independent service center. Vehicle inspected by manufacturer: yes. They attempted service but their repair only lasted a few months. Symptoms prior to failure: no. The problem is that the warning lights are turning on when they should not be. This matches the symptoms of Kia Technical Service Bulletin SA512, but the manufacturer's fix did not work.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
