2003 Dodge Ram 1500 Problems
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.
Some vehicles may develop a musty odor coming from the HVAC system, Dodge has issued a cleaner/disinfectant and a coating for the evaporator designed to inhibit bacterial growth.
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.
If a Check Engine Light illuminates indicating leak detection pump (LDP) failure, the cause is often pinched or disconnected vacuum lines to the pump. Vacuum lines should be inspected before replacing the leak detection pump. Contamination (carbon or debris) in the pump can cause failure and any hoses should be cleared before a new pump is installed.

RepairPal Expert Overview:
Chrysler has recalled certain 2002-2009 Dodge Rams (1500/2500/3500) because the wiper module assemblies may be susceptible to water intrusion, which may result in partial or complete loss of windshield wiper capability. This may cause reduced visibility for the driver, which could result in a crash. Dealers will replace the wiper module assemblies with vented wiper motor housings.
RepairPal Expert Overview:
Chrysler has recalled certain 1998-2003 Dodge Ram 1500/2500 models equipped with four-wheel ABS because aftermarket batteries may leak electrolyte onto the ABS control module connector, which can compromise the sealing integrity. This may allow development of a short circuit in the connector, which could eventually lead to a fire. Dealers will inspect the ABS control module connector for electrolyte damage and replace it if necessary.

2003 Dodge Ram 1500 Reviews
this is the 8th consecutive new Dodge truck I have purchased and worn out. I currently have 185K on her and she is using 1/2 qt of oil every 1200 miles. There are only 2 problems I have ever had - one is the Rt brake light, which shorts out when ever it rains causing a burned out bulb indicator, I have not been able to find the short anywhere. The second is when it has set for 24 hours or more, when you first put it in gear, it is as if the Trani has no fluid, the engine revs but it does not move. Dealership said it was a missing/defective back-flow preventer that was allowing trani fluid to drain over time and it takes 15 seconds to circulate the fluids. The recorded it and said if it became a problem, they would warranty it whenever I could not deal with the down time back then and skipped the service, here I am 185,200 miles later and never looked back
purchased my 03 ram 1500 quadcab used with 77K,had 1 year,replaced battery,and the tranny cooling lines,i live in the north east where salt is used on the roads during the winter,this truck runs like new,looks great and handles well for a large vehicle,interior is roomy and nicely appointed,the 4 wheel drive works flawlessly,although the transfercase shift on the floor is bit archaic,later years have the electronic engagement for the TC on the dash,just wish the hemi wasnt as thirsty,not a complaint,i knew it
it would be a gas hog,all in all a great truck!!!
I bought a 2003 Ram 1500 w/5.7 HEMI new. I have owned this truck since new and now have 105,000 mile on it. This truck has been excellent and has never let me down. Only minor issues in the last 8 years. Just now having to replace the upper/lower ball joints and shocks. Brakes have been done once since new. Wheel bearing hubs on both sides have been replaced. This is a big heavy truck, have to expect this kind of maintenance. Love the room and ride, much better than Ford /Chevy. Would buy another Ram. It's all in how you treat/maintain your vehicle.
I just bought a 2003 Quad cab 4x4 a few weeks ago with 160,000 miles a month ago. The body is in perfect condition, no rust except the corner of the door. The interior doesnt even look worn and it drives very well. I love the roomy interior also. But, after about a week, I noticed a jerking/vibrating in the rearend when accelerating a little hard and when pulling a steep grade. I am doing research to determine what is wrong with it, so if anyone has had this same problem, please feel free to give me a heads up @ email@example.com. I love this truck otherwise, but the gas mileage is terrible. Good thing its paid off or I couldnt afford gas for it.
i bought a used dodge ram 1500 4.8 liter with 96000 miles on it. i've driven the truck for almost two months and the check engine light came on, something to do with my air intake. anyone have any suggestions?
