Hey guys,

Just picked up a 2016 Cruze Limited and i'm loving it but right from the get go I've noticed that when the car is in a stopped position at a light or whatnot, or when in park, that it makes almost like a knocking sound coming from the engine. The best way to describe it is to picture your exhaust pipe knocking against your floor when at a red light or something. Is this sound normal for the Cruzes or should I bring it in?

Once I start driving past 20 kms/hr, the sound goes away. Can only be heard from the interior of the car. From the outside, there's no noise or knocking or anything.

Automatic transmission.

Definitely a trip to the dealer is in order. This is a first model-year car, there's bound to be little things like this that the 2016s will be discovering for a bit.

It's the 2016 Limited. That's the same old style of the previous years. The regular 2016 Cruze is the new model. :)

Probably the frequent fuel line banging the floor thing......or some other line.....figuring out which one can be tough but once figured out the repositioning is a non issue.

So they basically said it's just the sound of the engine. I guess I got accustomed to Chev's previous super quiet engines from the past (2012 sonic, 2007 g5, 2002 cavalier) so this one stood out to me. It almost sounds like a little diesel jetta engine at idle.

Is is "knocking" or ticking. The EcoTec engine line is sometimes referred to as EcoTick because these engines can be rather noisy at idle.

I don't notice it in my car, but it's very definitely loud under the hood.

I'll take it to the dealer in about 20 mins. Will post back results.

So none of you notice that the engine sounds louder when at idle or in a parked position? (While sitting inside the car)

I emailed my sales guy to arrange me sitting in another 2016 cruze to see if it does the same noise. I realize I'm pretty ocd with car noises and tend to notice things that others may not have caught on to. lol :(

Make sure its another LS with the same transmission (Manual or Automatic). The LT and higher trims have a different engine. The 1.4T engine is definitely quieter than the 1.8 in your LS.

They have no more 2016 Limited LS in their inventory :( Here's my mentality on the situation: The engine "noise" springs out to me because I had a 2012 sonic ls which is the exact same engine as the cruze, except the cruze has 35.7 ft. turning cycle and the sonic has 34.5 ft. turning cycle. The only other difference is that my sonic was manual transmission and this cruze is an automatic. Would that make a difference in engine sound when in a parked position or stopped at a light? (I'm good with identifying noises and how to fix them but my knowledge is still limited lol)

Sorry if I sound like a pain in the @$$. I just want to know if this is normal or not. I was always at the dealership with my sonic because it had a ton of issues so I'm trying everything in my power to stay away from them because I don't want to be annoying.

The two transmissions do sound different at idle. From the little time I've been in an automatic I felt it was louder than my manual.

I notice the same thing-- my LS is really loud, especially if there is a wall or another car nearby to reflect the sound. But I don't notice it on the road.

all engine/trans combonations i have sat in are loud. I sometimes feel my 2lt is broken, but then i remember that i just sit in a freight train when the car is at idle. totally normal. You are hearing a combonation of loud/noisey tranmissions and loud ticking fuel injectors. try sitting in the car running, and put the car in nuetral see if it gets better.

Can someone remind me what a bad dual-mass flywheel sounds like? (Does the 1.8 have dual-mass?) IIRC, it's most noticeable at low RPM.
