When ever the vehicle is in motion. Passenger seat does not have the reminder or warning system to alert the occupant to buckle up should they forget. My dealer states the passenger air bag system is active full time however it is only marginally effective should the passenger fail to secure their seat belt. Additionally, there is no dash indicator showing the passenger seat belt buclke/no-buckle status as shown on page 86 of the 2018 Silverado owners manual which discusses the passenger sensing system and airbag status indicator which is not present in this line of vehicles. Page 145 of the 2018 Silverado owners manual states there "may" be a reminder light near the airbag status indicator which is not installed on this line of vehicles. Viewing similar vehicles, this condition is present in a minimum of model years 2017 through 2020 Chevrolet and GMC 2500/3500 hd crew cab vehicles. Contacted General Motors customer service on 4/10/2018 & 4/24/2018 filed GM case [xxx]. GM rep called back 4/30/2018 and their solution was to have my dealership install an airbag on/off switch to disable the airbag. Not a suitable resolution to this safety issue.
