We recently purchased a 2016 canyon truck for about 45k with the new small diesel engine. on 10-19-16 we took it in to dealership for routine service and a major loud vibration rattling under the dash in the passenger air bag area. when we picked vehicle up we were told that they did not have a fix for noise coming from under dash air bag area and others canyons have been in for the same problem and that they are dealership waiting on procedure from gmc for fix? we have a concern that this could be a safety issue, since noise is coming from air bag area and would like your expeditious attention regarding this matter.
