Just purchased a new Escalade Prem Lux and the grid lines for reverse are missing and there’s an hour glass that won’t disappear. There’s Youtube videos with the same complaint. Took it the dealership and there’s a bulletin that they are working on it. How long does it take to just add them in. All the ones with the trailering packages have them so why is it taking so long? Very annoying to pay so much for a vehicle and it’s still missing this!
