What stands out
Owners have filed 55 lighting complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA lighting complaint has been filed on this vehicle in over 17 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 lighting 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
Turn signal malfunctions dominate complaints: activating the left signal triggers the right lights instead, or vice versa, with failures happening intermittently or constantly. Some owners report both signals flashing together or neither working at all. Repositioning the steering column or toggling the high/low beam control temporarily fixes the problem in some instances, but the malfunction returns. Multiple owners state they've had the multifunction switch replaced only to see the same failure reappear within a year. One dealer confirmed replacing four to five controllers in 2005 and 2006 Ram trucks alone.
Headlight failures center on low-beam loss despite good bulbs—no power reaches the socket. Owners replacing bulbs repeatedly without success report independent mechanics diagnosing TIPM defects. Dealers quote $800–$1,000+ for module replacement and reprogramming.
Windshield wipers intermittently stop working, often coinciding with turn signal failures. Toggling the stalk on and off multiple times restores temporary operation.
Owners report a broader TIPM issue: panic alarms trigger randomly; all vehicle lights cut out at highway speed; trailer lights fail after connecting the trailer. Dealership reflash procedures are limited to five resets before the module must be replaced—then the problem repeats.
One owner pulled over by state highway patrol for inoperative trailer signals cited the TIPM as incompatible with the tow package. A Kansas Highway Patrol officer independently verified a turn signal problem. Dodge issued a Technical Service Bulletin for the 3500 but refuses to acknowledge the same defect on 2500 models.
Failure modes owners describe
Reversed or cross-flashing turn signals
Turn signal lever input produces opposite signal output (left lever activates right lights or vice versa). Occurs intermittently or consistently; may affect front and rear signals, trailer signals, or both. Moving the steering column or cycling the high/low beam control temporarily corrects it in some cases. Repeated failures after dealer replacement reported.
When: Reports from 20,000 miles to 206,000 miles; commonly between 40,000–110,000 miles. One owner experienced failure within months of purchase.
Symptoms owners cite: Left turn signal lever activates right turn lights; Right turn signal lever activates left turn lights or no lights; Both turn signals flash simultaneously; Turn signals fail to work at all; Intermittent flashing or erratic timing; Trailer turn/brake lights inoperable when towing
Codes mentioned: TIPM fault, Multi-function switch failure, Turn signal relay failure
Repairs/costs cited: Dealer replacement of multi-function switch or turn signal stalk; one owner cited $400+ repair estimate. Dealers report multiple replacements needed on same vehicle. One owner reported Kansas Highway Patrol verified the problem. Repeated failures after replacement reported.
Recalls/TSBs owners mention: Dodge issued TSB for Ram 3500 but refuses to acknowledge problem on 2500 models. Dealer reflash procedure limited to 5 times before TIPM replacement required. No recall issued despite widespread reports.
Headlight failures and dimming
Driver-side or passenger-side headlight(s) stop working on low beam while high beam may remain functional, or complete headlight failure occurs. Bulb replacement does not resolve the issue. Owners report light output is dim or lights cut out entirely while driving. Affects towing operations and nighttime visibility.
When: Reports from 130,000 miles to 146,000 miles. One report at unknown mileage.
Symptoms owners cite: Low beam out; high beam works; Headlight cuts out while driving; Headlights turn off completely; Dim headlights; Right headlight stops working intermittently
Codes mentioned: TIPM defect
Repairs/costs cited: Bulb replacement ineffective. Independent mechanic diagnosed TIPM defect. Dealer quoted $800–$1,000+ for TIPM module replacement and programming. Owners report inability to afford repair.
Recalls/TSBs owners mention: Chrysler told owners to take vehicle to dealer and pay for repair; stated nothing can be done on their end. No recall issued despite multiple reports.
Windshield wiper intermittent failure
Wipers fail to operate at intended speed, stop working during rain, or malfunction simultaneously with turn signal problems. Toggling the multi-function switch on and off multiple times temporarily restores function. Wipers continue to operate even after switch is turned off, requiring repeated toggling to stop them.
When: Reports spanning vehicle's operational life; one owner experienced failures since 2007.
Symptoms owners cite: Wipers fail to work in rain; Wipers only work on intermittent speed; Wipers stop working with switch on; Wipers fail to turn off; Wipers malfunction with turn signal failures
Codes mentioned: Multi-function switch fault
Repairs/costs cited: Toggling switch on/off restores temporary function. Multi-function switch replacement reported in some cases.
TIPM-related electrical failures affecting lighting
Totally Integrated Power Module causes random, intermittent electrical disruptions affecting multiple lighting and electrical functions simultaneously. Panic alarm activates without input; trailer lights fail after plugging in trailer or minor electrical surge. All vehicle lights and exterior lights turn off without warning at highway speeds. TIPM has history of intermittent failures since 2006 introduction.
When: Reported at 132,410 miles and various mileages throughout vehicle ownership.
Symptoms owners cite: Panic alarm activates randomly; All lights turn off at highway speed; Trailer lights inoperable after trailer connection; Random vehicle electrical shut-downs; Intermittent random electrical failures; No warning lamps or fault messages
Codes mentioned: TIPM fault, TIPM power surge fault
Repairs/costs cited: Dealer reset/reflash procedure ($110 diagnostic fee); new TIPM module replacement expensive and problem repeats after replacement. Trailer plug connector touch causes failure; no fuse protection for trailer lights circuit.
Recalls/TSBs owners mention: No recall issued despite widespread reports and known TIPM issues. One owner notes TIPM known to cause random stall and other failures since introduction.
High-beam switch failure
High beams fail to activate or lights cut out completely when switching from low to high beams. At least one report of right high beam only not working.
When: Reported at various speeds during driving.
Symptoms owners cite: High beams will not turn on; Lights turn off when switching to high beams; Only right high beam non-functional
Codes mentioned: TIPM fault, Multi-function switch fault
Repairs/costs cited: Bulb is functional; no power to socket. TIPM module replacement cited ($800+).
Front turn signal indicators inoperable while rear work
Front turn signal blinkers fail to illuminate while rear turn signals operate normally. Drivers warned by oncoming traffic only for rear-facing vehicles.
When: Reported at 58,000 miles.
Symptoms owners cite: Front turn signal indicators will not operate; Rear blinkers only function; Loss of front-facing turn signal warning
Codes mentioned: Front turn signal relay failure
Repairs/costs cited: Dealer diagnosis: front turn signal relay failure; entire fuse panel replacement needed.

2006 Dodge 2500 mega cab. While sitting at a stop light in a left turn lane with left turn signal on, I experienced erratic timing of the left turn signal, and quick flashes of the opposite (right) turn signal. Moving the steering wheels direction seemed to remedy the problem, and I have not been able to duplicate the problem. *tr
2006 Dodge Ram 2500 diesel- the turn signal indicator frequently activates the turn signals in the wrong direction. I've noticed that adjusting the tilt column corrects the signal in most cases. There seems to be a flaw in the signal system that causes a short or something of that nature. I've had this problem since 2007, within months of buying the truck. It was infrequent at first and I…
