Noise cancellation in Summit level trim

1542 Views 2 Replies 2 Participants Last post by  sumyunguy
in MY2015 noise cancellation technology was installed on the Summit trim level.

Can anyone please give feedback on how well this works? Does the sound cancellation technology mute the Diesel engine sound as well as the road noise or just the road noise?

On my Summit it appears to attenuate all interior cabin noise. It is very quiet when on the highway, no engine noise or tire noise. Keep in mind it's a noise cancellation system. It's still there, just masked.
@GM Are you driving a diesel?
