Anyone know why there is a rattling sound when I am idle?? - Toyota Nation Forum : Toyota Car and Truck Forums

I have an automatic XRS. Everytime I'm at a stop and the shifter is in (D) drive, there is a loud rattling sound that I think is coming from the engine. When I put it in (N) neutral, it goes away and the idle is smooth again. When I put it back in (D) there it is again. But when I take my foot of the brake and the car begins to roll, it goes away. Anyone have any idea what this rattling sound could be? I have 7000 miles on my XRS and I'm worried that this sound might get worse and later cause a problem. Anyone?Please help. Thanks!

Take it to the dealer and have em take a peek at it.

I was going to but I thought someone might know on here. I really don't want to pay the $90 for the diagnostic check.

The car is in warranty, there should be no charge for them to look at it. Esp if you can reproduce it flawlessly.

yeah the factory warranty is supposed to cover that. so i dont see why youd have to pay the 90 bucks.

Sorry to bust in on your forum guys.Im from the Corolla section and I have the same problem with my 89 Corolla wagon.Its an auto as well.Im gonna post a message on the Corolla section and find out if the guys have any suggestions.Please let me know if you find out anything.

Hey there!!!I bounced this problem off some of the guys in the Corolla section and they think that the rattling is coming from a heat shield which is near the catalytic converter or it might be the cat itself breaking down.In any event,have your dealer take a look.Hope this helps!!!

looseness , defective mount parts . I am pointing this out due to an XRS ownwer in other FORUM ( matrixowners.com , matrixvibe.net ) that had a defective mount replaced . A poor mount possibly / can cause vibration . Second of all , we have a problem w/ our base MATRIX w/ 4 speed auto . Ours clanks when put into reverse . The click is when put into reverse or drive . It also clicks when accelerating from a stop . Apparently TOYOTA / PONTIAC are aware of these quirks and are telling their SERVICE DEPARTMENTS that this is normal . Baloney !!! Hope this helps .

Good Luck
