Dodge Ram 1500 Problems
RepairPal has identified the most common problems with the Dodge Ram 1500 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
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.
If the engine cranks but does not start, or starts and stalls, the fuses should be inspected, especially the power door locks fuse. The power door lock fuse provides power to a module that sends the Powertrain Control Module (PCM) the "OK to start" signal.
On the 3.9L V6 and 5.2L V8, rerouting the ignition coil wire and spark plug wires can help solve a misfire and/or surge problem that occurs at approximately 45 mph. A service bulletin was published that outlines the specifics of the repair. It states the rerouting procedure should be performed before other repairs are done for misfires, surging or spark knock.
On the 3.7L V6 and 4.7L V8 the camshaft position sensor may fail and cause the engine to crank but not start or it can cause intermittent stalling. A failed camshaft sensor will require replacement.
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.
If the vehicle will not shift into, or out of four wheel drive, and the "Serv 4WD" warning light is illuminated, the front axle disconnect actuator may need replacement and a power module (TIPM) may need a software update.
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.
On 3.9L V6 and 5.9L V8 engines, the intake manifold gasket may leak and cause increased oil consumption and a spark knock during acceleration; the gasket should be replaced.
The drip rail door seal may become torn form contact with the lower A-piller. A revised secondary door seal is available to correct this concern. This is not a recall but a technical service bulletin (TSB) which means the failed part will be replaced at the customers expense once the warranty has expired.
The transfer case in the Dodge Ram 1500 has multiple gear ratios, which can be selected by moving the switch in the cabin to 2Hi, 4Hi, or 4Lo. It has been known to shift to 4Lo without warning, at any speed, and whether the vehicle is on or off. If this occurs at highway speeds, the result can be catastrophic failure of the transfer case.
This is caused by a faulty four wheel drive shift motor, selector switch (in the cab) or the wiring between the two. The most common cause is the transfer case switch, which is an electric motor mounted on the transfer case.
To correct the issue, inspect the wiring to the transfer case switch motor for damage, and replace the shift motor if needed. Disconnecting power to the shift motor will lock the transfer case in its current setting.
