I have a few thousand miles left on my RRS 5.0 and want to maximize the warranty before it runs out. So far, I’m hearing some occasional exhaust noises/thuds on downshift and acceleration (just got this car a few months ago so maybe this is normal)—not exactly sure where it’s coming from. And one interior ambient light is out. Otherwise, no issues. Anything. I should look out for? Anyone know how to get a dealer to take a comprehensive look at the vehicle for repairs (preferably at no charge)?
