Does a 2015 GMC Terrain have a backup alarm?
My 2015 terrain doesn't alarm you when you get close to something. Do they
have the backup alarms or is it possible that it's shut off? If it's shut off, how do
you turn it back on. Thank you.
I am sure it was an option. Look for the sensors in the rear bumper.
