Body problems of the 2012 Nissan Quest

My 2012 Nissan Quest has completely rotted out causing the muffler system and the motor mount to move causing significant damage and repair. Over $2,500 just to buy parts and repair all due to excessive rust on the body frame underneath. Its only a 2012 yet it looks as if it is a lot older. While driving the muffler system failed and broke away along with the motor mount which shifted. Cannot be driven any longer.

Driver side door won't open, if in a emergency case how can the driver get out of the car.

Broken driver side door lock accuator caused the door to not open. The mechanical door lock system malfunctioned resulting in a door that is locked and will not unlock to open. This is a safety hazard that will prevent safe exit in the event of an emergency.

I was driving today with my family on my 2012 Nissan Quest when all of the sudden the right back door open and close while I was driving on the highway, luckily my daughter was wearing her seat belt and nothing happened this is unsafe, this is an unsafe car to drive, I went to the dealer and they said they cant fix it because is a long weekend and they dont want to work. This is not the way to treat a customer, you get pay to work then do you job. Nissan are the worse car. I will hold Nissan 100% responsible if something happens to me or my family while driving this vehicle.

May 2014, I had a wet driver side a pillar that was leaking. Nissan attributed it to a defective sunroof with a crack. The headliner, subwoofer and amplifier were replaced. On July 10, 2015, I took my car to a flagship carwash. After my car was washed I noticed water on the right side of the rear sunroof and on the headliner in the rear of the vehicle on both the right and left sides of the car was wet in all the above noted locations. My radio also stopped working. Nissan had my car for five days and said they could not recreate the leak or determine what was wrong with the radio. They would not look at the radio as it was not under warranty. I took my car to a local radio repair shop and they discovered rust behind the panels in the rear of the vehicle, in the cargo area and 2 inches of water under my cargo area. Vehicle was purchased Feb 2013 new.

Automatic rear doors cannot be stopped from closing once activated and a person can get crushed in the door.

My car randomly accelerated on 2 occasions , may 30, 2013 and June 27, 2013. The first incident resulted in a crash, hitting a pole, tree, and another vehicle. 2nd incident was a near miss, almost had a head on collision with another vehicle. My 9 year old son and I were in the car. No resolution from Nissan. They are not concerned about safety. Want me to take car back without any explanation.
