Car is cranking but not starting, has to wait about an hour, then it starts. It happened twice (at that time, I was in
rush, stop the engine and start back right away in couple minutes). Why and what is potential issues?
Also, today I have tried 4WD button for a short time (5 min) at 25-30 miles speed, hearing sharp noise couple times on the right. If I depressed the 4WD button, the noise is gone. Why? Is anything I need to be aware of?
or should I not use 4WD option at all?
