Vehicle braking system gets activated too often. Dealership services cannot find anything nor accept there's any issues. Today 08/15/2024 the vehicle locked up the brakes, while driving at 55 mph; injuring a 15 yr; 12 yr; 11yr; and 57 yr. Grandmother. Called dealership services and stated they will see vehicle, but don't believe to find anything, as before. Two of my family members sustained neck injuries. Can you please help. Vehicle can be inspected anytime. Please call first.
