The battery was dead. Clicking noise from the engine compartment. Jumped the car. The tire pressure display has a fault (does not display the tire air pressure).
Could it be a blown fuse. Where is the fuse for the tire pressure?

Then this morning my cars rear end was sitting on the ground?

As the vehicle hits normal bumbs on the road there's a squeeky sound that resembles an old squeeky bed spring in motion.

put in a new battery. the last two days had to get jumped in the morning. Does anyone else have this problem or know whats causing it? there have been no malfunction codes and car is without power in the morning.

left rear of vehicle lays down over night,comes up when i start the car and push suspension button,and works fine all day,no visible leaks,no trouble lights on in car,is it the pump,shock,control module,a leaking valve,ect?????
