If you are complaining about a noise, you might want to post an example.
The driveline in the renegade is not super quiet. There's a difference between not liking something and it being broken.
Without an example, we can't tell if you are complaining about something actually wrong, or just about the way the car is.
If the car isn't actually broken, good luck with the lemon law attempt. There are usually requirements to be met regarding the nature of an issue. Simply not liking the way the vehicle sounds probably doesn't make the cut.
