On some models a void in the rear window seal may cause a water leak. Water may be present on or under the carpet. The seal will need to be replaced if that is the source.

Most Reported 2009 Dodge Ram 2500 Problem Reports
Engine overheating can result from coolant leaks which are commonly found at the thermostat housing gasket, water pump, heater return tube O-ring at the water pump, intake manifold gasket, and timing cover gasket. Our technicians recommend a complete inspection of the cooling system after any repairs are made to be sure there are no other leaks.
The thermostat may fail to close completely, causing the Check Engine Light to illuminate. This problem will prevent the engine from reaching normal operating temperature; a new thermostat should be installed.
If the engine does not crank (or cranks but won't start), the wireless control module (WCM) may have locked up. This is due to static discharge through the ignition key. A revised model should be installed, but simply disconnecting the negative terminal of the battery for thirty seconds will temporarily reset the module so you can start the car.
If a clunking or "loose lumber" noise is coming from the front or rear suspension, there are revised shock absorbers available that can help the concern. This is usually heard at lower speeds and colder temperatures when driving over bumps.
