2003 Dodge Ram 3500 Problems

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.

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.

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.

2003 Dodge Ram 3500 Recalls

The left and right tie rod assemblies are part of the front steering linkage, Certain trucks are being recalled because the left tie rod can break unexpectedly. This can result in loss of steering control. Dealers will inspect the steering linkage and install a new left tie rod assembly as necessary to correct this concern. This recall supersedes a previous recall, some vehicles repaired under the first recall may require an additional repair.

Certain vehicles may have been assembled with a left outer tie rod ball stud that may fracture; others may have received the affected tie rod assembly as a replacement part during normal service. This condition tends to occur during low speed parking lot type maneuvers when the driver is making a tight turn. This condition could result in a loss of directional stability in the left front wheel, increasing the risk of a crash. Dealers will inspect the tie rod ends, replace the left outer tie rod end as required, and perform a front end toe alignment as needed. The manufacturer has not yet provided an owner notification schedule. The Chrysler recall number is L16.

2003 Dodge Ram 3500 Reviews

i will never own another dodge truck! had several problems with air conditioning, drive train, power steering and now compression issues with 74k miles. very bad purchase!

I LOVE MY TRUCK. PULLS EVERYTHING UNDER THE SUN BUT THE HEAT/AIR DEFLECTOR WENT OUT UNDER WARRANTY AND THEY FIXED IT. BUT A YEAR AGO, IT WENT OUT AGAIN. AND NOW FOR THE LAST MONTH, IT WON'T CRANK WITHOUT PLUGGING IT UP OR USING ETHER. NOT SURE OF WHAT IS CAUSING THE ENGINE NOT TO START. FROM THE RESEARCH I HAVE DONE, IT COULD BE ANYTHING FROM THE GLOW PLUG TO A CRACKED FUEL LINE.

I have owned 4 dodge trucks with cummins now have put over 300000 on 97 200000 on 2001 over 100000 on 2003 and over 240000 on my main 1 ton, i was 100% ford until 97 when i finally had to give up on ford due to bad customer service. went to dodge with cummins and manual trannys have over 250000 on my main driver now with original clutch and pull 20000lbs often, standard maintainance as expected...
