What stands out
Among the 6 model years of Dodge Ram 3500 in our records for electrical problems, this one ranks #3 by owner-complaint volume.
No new NHTSA electrical complaint has been filed on this vehicle in over 10 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
The dominant issue is catastrophic TIPM failure. Owners report the module overheating, smoking, and catching fire during normal driving and while parked. One owner experienced three separate TIPM failures (2011, 2013, 2015). When the TIPM fails, the truck loses all electrical power and engine control. Critically, the vehicle sometimes starts itself without the key in the ignition while also losing steering and braking capability. One owner pulled a trailer through a mountain pass with no power steering or trailer brakes after TIPM failure. Another owner's truck moved 10 feet on its own before stalling, in second gear. Multiple owners report the module visibly burning internally, with one showing a quarter of the main circuit card disintegrated.
Beyond the TIPM, owners cite an electronic throttle controller that fails repeatedly—one owner replaced it six times, and all six replacements failed between 7 and 40 miles of driving. Turn signals operate backwards on at least one vehicle, triggering opposite-side lights and creating highway collision hazards. Dashboard lights flash intermittently due to wiring harness faults in the steering column. Tail light sockets overheat and melt from 1157 bulbs. At 621,000 miles, the instrument cluster and odometer seize entirely.
Owners consistently note that Dodge has been made aware of these issues but has not issued recalls.

Failure modes owners describe
TIPM (Totally Integrated Power Module) thermal failure and fire
The TIPM overheats, smokes, and catches fire while driving or parked. Internal circuits burn and disintegrate. Failure typically cuts engine power, kills all electrical functions, and sometimes causes the vehicle to start itself without the ignition key turned on or the vehicle in gear, creating uncontrolled movement without steering, brakes, or transmission control.
When: Various; earliest documented 2011, repeated failures at 64,000 miles (second occurrence), 160,000 miles, 245,000 miles; some owners report multiple failures on the same vehicle
Symptoms owners cite: Smoke and burning odor from fuse box or under dashboard; Engine stalls or shuts off completely; Loss of all electrical power while driving; All electrical components activate simultaneously (wipers, horn, lights, washer pump); Vehicle starts itself without key in ignition; Steering and brakes become inoperable; TIPM box visibly burned or disintegrated internally
Repairs/costs cited: TIPM replaced under warranty (first occurrence for some owners); repairs cost unspecified but recurring failures documented at 2013 and 2015 for one owner; one owner reported repair did not resolve issue
Recalls/TSBs owners mention: Manufacturer notified in multiple complaints; no recall issued; one owner characterized this as a 'known problem' and 'common occurrence'
Electronic Throttle Controller repeated failure
Electronic throttle controller fails repeatedly, causing loss of engine power and drivability. One owner replaced unit six times; all six replacements failed within 7–40 miles of operation.
When: Occurs at variable mileage; failures clustered in early miles after replacement
Symptoms owners cite: Truck loses power and drops to idle speed unpredictably; Occurs at any speed, including highway speeds (70 mph noted); Requires engine shutdown, slow accelerator cycling, and restart to restore function temporarily
Repairs/costs cited: Electronic throttle controller replaced six times; all replacements failed between 7 and 40 miles; owner states unable to get permanently repaired
Turn signal and wiper control malfunction
Turn signals operate on opposite side (left signal triggers right turn, and vice versa), and wiper function becomes erratic or non-responsive. Creates serious safety hazard when lane-change signals are misinterpreted by other drivers.
When: Shortly after purchase (one case); timing unclear for wiper issues
Symptoms owners cite: Left turn signal activates right turn lights and vice versa; Wiper function does not track with intended lever operation; Problem occurs during active driving and highway lane changes
Dashboard lights and wiring harness electrical faults
Intermittent electrical faults in the steering column wiring harness cause dashboard lights to flash unexpectedly. Issue resolves temporarily with key-off restart but recurs unpredictably.
When: Occurs intermittently during vehicle use
Symptoms owners cite: Dashboard lights flash or flicker without driver input; Issue resolves when vehicle is turned off and restarted; Problem recurs sporadically
Repairs/costs cited: No repairs documented; one owner performed manual wire separation under steering wheel
Tail light bulb socket overheating and melting
1157-type tail light bulbs overheat and melt the plastic socket and surrounding housing, causing tail light and related components to fail.
When: Timing not specified
Symptoms owners cite: Tail light bulbs overheat; Plastic socket melts; Surrounding plastic housing degrades
Repairs/costs cited: Bulb and socket replacement required
Instrument cluster and electronic control module failure at high mileage
At approximately 621,000 miles, the odometer seizes and instrument cluster becomes inoperable. Dealer indicated this is a known issue when vehicles reach this mileage threshold, requiring instrument cluster and/or electronic control module replacement.
When: Approximately 621,000 miles
Symptoms owners cite: Odometer freezes; Instrument cluster stops functioning
Repairs/costs cited: Instrument cluster and/or electronic control module replacement required; vehicle was not repaired per complaint
Recalls/TSBs owners mention: Dealer acknowledged this as a known issue not in public awareness

What owners are reporting 1 most recent
On three different occasions, the tipm has failed on this truck. The first time the vehicle was under warranty. Second one happened in 2013. The third time in dec of 2015. All three times the motor quit in heavy traffic and the dashboard went off. The tipm box then started smoking. I disconnected the battery cables. On the third occasion, I was delayed by heavy traffic in getting to the…

A quarter of owners report trouble before 91,000; a quarter make it past 205,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $850 for electrical repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to electrical?
No active recalls currently cover electrical issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
