My elderly parents bought a 2011 Equinox with the 4-cylinder engine in it that sounds like a sewing machine at idle. It was used with about 14K.

The dealer blew me off saying it was supposed to spound like that at idle because the ecotech engine uses low fuel pressure at idle or soemthing, but I wanted to get another opinion. This particulare Chevy dealer doesn;t have the best repuitation for service.

From what I've read on here, this may be a common problem, but I am unclear as to what the fix is. Thank you for your time.

I assume you're talking about a clicking noise or something that resembles valve clatter....what you're hearing is the direct fuel injection system. Technically there is nothing actually wrong with the engine (and the dealer should have explained this) but there is an insulator shield that can be installed on the high pressure fuel pump (not low pressure) by the dealer if they find it bothersome.

I think direct injection systems are just noiser than we are used to. I was out of town recently and rented a Kia Optima, and it just made a ton of noise like a diesel at idle. It ran fine, but was much noiser than the V6 in my Terrain.

As long as I don't hear anything in the cabin I'm fine ;D. If theres one thing everyone can agree GM scored a home run on with the Equinox/Terrain, it is the rock-solid noise cancellation. Definitely the quietest car I've owned.

I agree....and have only driven one other car as quiet inside..the Buick LaCrosse...and one other car that is even more quiet....the new restyled Chrysler 300 (amazing!).
