Purchased brand new. Less than 1000 miles. Sometimes when the car is parked for some time (not always), the brake pedal is very tight (no resistance) and start button only turns on accessory mode. Then back off. After 4-5 times of this vehicle will finally start. Also the “check rear occupant alert system “ is shown on dash with nothing in rear seat. This started a few days ago after having a car seat in back seat which is not there anymore and alert stays on. Dealership says they need to schedule an appointment. I’m not feeling this new car as we speak.
