The owner of a 2021 Ram 3500 expected a dependable heavy-duty truck built for serious work, but the vehicle’s repair record told a different story. The truck started developing electrical and camera-related faults that proved difficult to resolve. The first major visit occurred when the backup camera began showing a black screen instead of an image.
Technicians traced the issue to wiring damage inside the tailgate and evidence of water intrusion around the third brake light assembly. Over several days, they replaced the tailgate harness, camera, and light assembly, updated the radio software, and verified that both the cargo and rear cameras were functioning again.
Not long afterward, the truck returned to the shop for running-board problems. The owner reported that the powered steps would stay extended after the doors were closed. The service department found a loose driver-side mount and a passenger-side linkage motor that was binding during operation. They replaced the motor and linkage assembly and tightened the mounts before confirming normal function.
After some time passed, more serious electrical issues began appearing. The Ram had to be towed in after failing to start. Diagnostic scans revealed more than forty fault codes, multiple inoperative modules, and signs of rodent activity under the hood. After extensive tracing, technicians discovered a shorted circuit inside the power distribution center (PDC). They replaced the PDC and re-tested the truck until it started and shut off properly. Despite that repair, the vehicle continued to suffer from erratic electrical performance, including dead batteries, module communication errors, and charging failures that left it undriveable.
A few weeks later, the owner brought the truck back again after repeated no-start conditions and a warning about the charging system. Technicians determined both batteries had internal faults and replaced them before performing multiple software updates to the powertrain and transmission control systems. Even with the new components and flashes installed, the records show that the truck experienced ongoing electrical instability that affected critical systems.
Over a series of visits spanning many months, the Ram 3500 spent weeks in the shop for electrical diagnostics, part replacements, and re-programming. Each time, the truck was returned as “operating as designed,” only for another electrical problem to surface shortly after. The repeated failures of essential components like cameras, wiring, batteries, and starting systems left the owner with an unreliable vehicle that could not be trusted for daily use or towing duty. If this story sounds familiar to you, you may be entitled to relief under your state’s lemon law.
