Is this a good car?

the other day i was driving my car when from anywhere the brake pedal gets really heavy to stop the car, it does not goes down to stop the car fast three hours later it was fine. We have been serve the car for a problem in the front suspension where they supposed to remove front rotors and brakes , i think is air in the lines, and want to know the symptoms of this kind of trouble.

90,000 km. Vehicle is locked remotely and within seconds the trunk and doors locks open by themselves. This just started today. I disconnected positive battery terminal then reconnected but the malfunctioning locks still occurs.

what happened will it turn on when driven in water up to half my tires

When it works it is great but when is shuts down it blow RED hot air. The compressor is working but the tubes coming into the car are hot. My dealer says he can only fix it if it is not working when I take it in. I can start for the dealers service center and by the time I get there it is working fine. Anyone got any ideas. I have read a lot about MB AC's. They seem to have a history of not working right.
