Problems with the pneumatic system can cause closing assist and door lock issues.
The crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance.
The engine wiring can degrade because the insulating material falls off leaving the bare wire exposed. This can cause many problems depending on which wires are exposed and what they touch.

I have to manually push down and up on all the doors to lock and open, the driver door I have to use the key to open and look. The doors do slowly close with that close assist feature but the trunk has to be slam shut. Fuses are all ok. I can hear the closing assist pump make a little Hiss sound ...
the noise is coming from the passenger side underneath more so towards the rear tire. Its very loud and it sounds like a annoying jet sound and it stays on all the time. Actually it's a very Embarrasing sound when stop idling.
