2016 Cadillac Escalade electrical system problems

Tl* the contact owns a 2016 cadillac escalade. Every time the contact parked and locked the vehicle, the brake lights remained illuminated. The dealer replaced the sensor under the brake pedal twice. During the third visit, the dealer replaced the wires after speaking with the manufacturer; however, the failure still persisted. During the fourth visit, the dealer kept the vehicle for 28 days, but the failure could not be duplicated. The failure recurred. The manufacturer was contacted.

The adaptive cruise control radar sensor was found crack after being taken to the dealership for error code. ( their was no physical damage to the front bumper or the bottom of the bumper of the vehicle. GM failed to replace the part under warranty because they say there is physical damage to the part needed to be replaced. I believe the part should be in location where road debris can hit the part. Service advisor has said this is known issue with this cadillac model.
