I live on a dirt road Jack Williams (where I got the tires) said the rear alignment was off due to the pot holes and dirt road. As for replacing all 4 tires yes I did and even had the alignment done 2 weeks ago. When the lights came on I drove straight home and parked it so I didn’t check the cruise control. Calling the dealership where I purchased the vehicle tomorrow (hoping they are open). The car is still under warranty so hopefully they will fix it.
