hey guys i have a 08 g37s AT and recently i noticed when im driving in normal drive and i begin to brake my revs shoot up a little over 1k rpm. Another issue is when i turn the steering wheel all the way the car revs up on its own in a jerking manner?

all i have is an ark cbe and i still have warranty on my car, is there a term for these problems

 

No thats normal nothing wrong with your car
