q60 Start up sound

In 2014, the G37 Sedan became Infiniti Q50. G37 Coupe and Convertible became Infiniti Q60 under Infiniti's new naming structure - Here's the place to discuss the Q50 and Q60!

Car: 2017 Q60 Premium V6 twin turbo

Post

Hey guys, I purchased a 2017 q60 Premium V6 twin turbo about 1/2 a year ago and I love the car. The thing is that I'm still not really used to the sound it makes when it starts up and idles. I've never had a turbo charged car before, but I feel that the start up sounds a little rough, kind of like a diesel engine. I also think that the valves are a little loud on it. IDK if that is normal or if there might be something wrong. I have checked the oil and there are no leaks and the oil is at the normal level. There were a few times when I've heard a chirping sound, I have assumed its one of the drive belts, but they all look good. I'm only concerned because for the car to be a 2017 its a little too early for this kind of stuff. Any ideas or feed back on the experience from other q60 owners would be great.

Thanks

Are you talking cold start or warm start? Cold start the car will heat the catalytic converters and will make noise for 10+ seconds, warm start it won't do that. It does run rougher/noisier than the prior 3.7 regardless.

Thank you for the feed back.

Today I got a chance to record under the hood.

I don't know if it is normal for one side to sound louder than the other side of the engine. To me it sounds like the sound is coming from the valve cover. The other side is not as loud and does not sound as metallic, this sound is made when the engine is hot or cold.
