A Hyundai Technical Service Bulletin #10-EE-001 (Mar/2010) Discusses Starting Problems With 2009 & 2010 Sonata Models With The 2.4L Engine During Extended Below Freezing Conditions.
Again, an excellent 5 page detailed bulletin with nice drawings and guidance.
Cars with this problem just click with no cranking during starting attempts.
The starters will operate normally after several attempts to crank.
If this describes your situation and it’s been below 32F for periods when you have this problem then the starter may need a Starter Solenoid kit 36120-2G110.
See a dealer for availability and application.
