Its hit or miss, some DI engine are louder than others. I have no complain of ticking noise on my GS, inside or outside of the car. Now, rattle noise, thats another story

do you guys want a super quiet car inside/out?

or would you like some louder exhaust note to drone out the ticking?

Hi Guys, I am in the process of buying a 07 IS350 and heard the noise. Aside from being annoying, is there any reason not to a buy a IS with the ticking noise? Could the ticking noise lead to other issues down the road? Is it better to avoid an IS with the ticket noise?

The vehicle I am interested in buying is a great deal.

The ticking noise is normal. It's coming from the Direct Injection system. All DI system makes ticking noise. No matter if it's a Lexus, Audi, Mercedes Benz, BMW, etc...

The GS/IS w/3.5 is one of the best used cars you can buy, and I did much research. Wish I could find the equivalent in a woman!
