when you say you hear rattles do u mean when your driving or when you turn your car off. i was very dissapointed tonight to hear that tat tat tat sound coming from my car after i turned it off. is that normal?
i recently purchased a black IS 350 i was wondering if you guys have an tips on breaking the car in. also when u guys turn your car off do you hear any sounds from the engine. like popcorns being made under the hood somewhere.
