1994 Dodge RAM 3500 Problems

What owners report

Owners of this model year most often describe brake and front-suspension behavior - a soft or sinking pedal, ABS that engages in wet weather, and a violent front-end shake after hitting a bump. A second cluster of complaints concerns dash and wiring heat, with several owners reporting smoke or fire at the headlamp switch or under the dash. Reports arrive across a very wide mileage range, from a few thousand miles to over 200,000, so condition and prior repairs matter more than odometer alone.

1. 1
   Electrical system

   Headlamp switch and dash wiring heat or fire

   • 13 complaints (19%)
   • median 148,639 mi at 21.5 yrs old (1 states mileage, few)
   • 6 mention a crash, fire or injury
   • filed 1997–2017

   Owners describe headlamps that switch off intermittently, and in some cases smoke or flames from the headlamp switch, under the dash or at the ignition switch. Some complaints note the wiring harness was not replaced when the switch was, and that the problem returned afterward. Reports also describe a melted ignition switch and a melted blower motor and harness. Reported across many model years of use, with several complaints filed long after the truck was new.

   Recall 99V024000

   What to check: Ask whether recall 99V024000 headlamp switch work was completed and whether the wiring harness was replaced at the same time, and inspect the switch and under-dash wiring for discoloration or a burning smell. Test the headlamps over a long drive with the switch on.

   “It was rainy day and vehicle had been driven about 2 hrs before incident. Vehicle was parked and consumer noticed smoke inside car. Fire was coming up through the dashboard between the headlight switch and VIN. Contacted dealer and manufacturer. They investigated, and claimed they were not responsible if over 12 months.”

   NHTSA complaint #856417, filed 2000-02

   “Nhtsa recall campaign 99v024000 headlamp switch; the headlight switch failed shorting out which caused the headlights to go out while in use. The switch failed again but this time the wiring harness under the dash caught fire while being driven. There was a recall issued on the RAM 3500 for this problem but the same failure has occured on this ram 2500 pickup. Please describe details ts”

2. 2
   Brakes

   Soft or sinking brake pedal and ABS behavior

   • 11 complaints (16%)
   • median 200,014 mi at 13.1 yrs old (1 states mileage, few)
   • 2 mention a crash, fire or injury
   • filed 1995–2007

   Owners describe the brake pedal going to the floor or sinking under steady pressure, and ABS engaging or locking up in wet conditions so the truck will not stop as expected. Some say the pedal pulsates, that the truck pulls or slides, and that brake pads wear quickly under load. Complaints also mention loss of braking control while backing up and brake work done at the owner's expense. Reported from the first years of use through high mileage, with several complaints tied to wet roads or heavy loads.

   What to check: Check pedal feel with steady pressure and look for a low or leaking fluid reservoir, plus wet-weather ABS function if you can test it. Ask whether the ABS light is on and whether the hydraulic system has been serviced.

   2 excerpts from owner complaints in NHTSA records

   “When brakes are applied in wet conditions only ABS system locks up. Vehicle is unable to stop. Pedal is hard and vehicle shakes when brakes are applied. Consumer states vehicle pull from side to side at random.”

   NHTSA complaint #801076, filed 1996-08

   “The truck loses it's braking power when backing up. The brake pads have to be changed every 5 to 10 thousand miles. The brakes on the truck are not large enough for that size truck.”

   NHTSA complaint #822007, filed 1998-03
3. 3
   Suspension

   Front-end shake after hitting a bump ("death wobble")

   • 6 complaints (9%)
   • median 95,000 mi at 12.6 yrs old (3 state mileage, few)
   • filed 1995–2014

   Owners describe a violent shaking of the front end that starts when the truck hits a bump or expansion joint at highway speed, sometimes strong enough that they have to slow sharply or stop. Complaints mention loose or worn front-end parts such as the track bar, a torn stabilizer bar bracket, and a reinforced shock tower, and in some cases a transfer case failure alongside the shaking. Several say the dealer could not identify the cause on the first visit. Reported from roughly 60,000 to 173,000 miles, often at highway speeds after a bump.

   1 related service bulletin

   What to check: Drive the truck at highway speed over a bump or rough pavement before buying, and have the front track bar, stabilizer bar mounts, ball joints and shock towers inspected. A service bulletin from 2018 describes inspection of front upper ball joints for excessive rotational friction, so ask whether that part has been checked or replaced.

   2 excerpts from owner complaints in NHTSA records

   “While driving 35-40 MPH vehicle ran over a small bump. This caused the vehicle to vibrate severely. Vehicle was taken to the dealer, who informed consumer that the stabilize bar bracket was ripped from the frame.”

   NHTSA complaint #10099292, filed 2004-11, 173,000 miles

   “Entire cab shakes at various times while driving. The dealer could not determine problem. When shaking occurs the vehicle is difficult if not impossible to steer, this resulted in driver having to go off the side of road several times.”

   NHTSA complaint #521127, filed 1997-08
4. 4
   Transmission and drivetrain

   Transmission fluid leaks from cooler and pressure lines

   • 5 complaints (7%)
   • typically at 6.0 yrs old
   • filed 1998–2017

   Owners report transmission fluid leaking from cooler and pressure lines, in some cases because lines rub against each other or a plastic fitting melts, and fluid reaching the exhaust and converter. A few describe loss of power or loss of drive when the fluid escaped. Complaints also mention a failed auxiliary cooler and general transmission failure during operation. Mostly described on trucks with no mileage given in the complaints; several reports come from vehicles well past 100,000 miles.

   1 related service bulletin

   What to check: Look under the truck for fluid trails on the cooler lines, exhaust and rear of the driveline, and check the transmission fluid level and color. A 2018 service bulletin covers inspection of replacement cooler line assemblies for improperly crimped fittings, so ask whether the lines have been replaced and with what part.

   2 excerpts from owner complaints in NHTSA records

   “Noticed transmission leaking underneath. It was leaking onto the exhaust system pipe and catalytic converter, clearly back to the brakes and rear bumper. Contacted dealer who was not able to help due to expired warranty. Transmission cooler lines were clamped together where they can rubed each other and wore out.”

   NHTSA complaint #852787, filed 1999-11

   “The plastic fitting on the transmission pressure line becomes hot and melts, allowing the transmission fluid to leak out. At this time all power is lost and driver has no control over the truck. The problem has been corrected at owner's expense.”

   NHTSA complaint #823205, filed 1998-05
5. 5
   Fuel system

   Stalling or no-throttle-response

   • 6 complaints (9%)
   • median 200,000 mi at 21.6 yrs old (1 states mileage, few)
   • filed 1995–2017

   Owners describe the engine shutting down without warning while driving and being hard to restart, with a computer replaced more than once and a fuel pump replaced. Others report the throttle becoming unresponsive when pulling into traffic, traced by the dealer to a throttle position sensor that was unavailable. One complaint describes a frayed throttle cable and a foot-feed linkage with plastic ends that pop out. Reported on trucks at high mileage, from about 150,000 to over 200,000 miles in the complaints that give mileage.

   1 related service bulletin

   What to check: Ask whether the throttle position sensor and fuel pump have been replaced, and inspect the throttle cable and linkage for fraying or loose plastic ends. A service bulletin notes checking the injector wiring loom and connector before replacing injectors for certain injector circuit codes.

   2 excerpts from owner complaints in NHTSA records

   “When driving at 45 MPH without prior warning the vehicle shut down. Driver pullrd over, and when tried to restart the vehicle, the vehicle kicked over and shut back down. The consumer took the vehicle to repair shop. The computer system had to be replaced twice, and the fuel pump also had to be replaced. Currently, the pressure is building up inside the vehicle, and the cosnumer states there wasn't any problem with the pressure until the dealer replaced some parts.”

   NHTSA complaint #831424, filed 1998-11

   “Vehicle of will stall intermittently. Problem is more frequent during warm weather. Dealership has examined vehicle numerous times, but could not determine cause. Please provide any additional information / attachments.”

   NHTSA complaint #897569, filed 2001-10

Buying note. These trucks are old enough that condition and service history matter more than mileage, so have the front suspension, brakes and transmission cooler lines inspected before purchase and confirm whether the headlamp switch recall work was completed. Parts availability can be an issue, as some complaints describe discontinued components, so check that needed parts can still be sourced.
