Hello my wife drives a 2014 suburban LT and in the past few weeks at around 70 mph there is a buzzing sound in the dash on the driver side it stops at around 75-76mph anyone have any idea what this could be? Thanks

have you taken note of what RPM that is equal to, opened the hood of the car, and while someone holds the engine at that speed checked to see if the source of the noise is actually coming from the engine?

Thx zora tried that yesterday afternoon couldn't duplicate. The noise is like a electrical buzz kind of like a relay but a lot faster rhythm

Any chance that this truck is still under a warranty? Just saying...

unless they exceeded mileage would think it would be covered and they should just take it in to a dealer rather than have us guess what the noise is.
