Noticed loud rattle upon start up.
Sounds like valve lifters getting no oil for a few seconds.
Had 4000 miles on car, took to Chevy dealer, he recommended changing break in oil and kept car overnight to listen to noise.
Said he heard noise, but put otherwise on invoice???
If Equinox keeps this up now at 6000 miles I will start to battle with the folks on the complaint line.
I previously had a Chevy Colorado of which 2 cylinder heads had to be replaced(factory defect) which they would not admit to, so this is how GM is.
