Owners report three distinct lighting problems on the 2013 Ram 1500. The most widespread complaint is inadequate low-beam brightness. Owners describe the halogen and standard low beams as too dim and yellowish, forcing them to rely on high beams for safe visibility. One owner noted dealer adjustment didn't help; another compared the lights to different vehicles with superior output over 35 years of driving experience. Several owners report seeing the same issue on other 2013 Ram trucks they've encountered.
The second major issue is moisture accumulation inside sealed headlight housings. Owners report condensation, fogging, and "fog-like" effects that develop in both single and projector-style units, reducing light output and visibility. One owner had the dealership replace both headlights, but the new units developed the same moisture problem. A dealer told one owner the moisture should dissipate within days, but owners say it doesn't. FCA's TSB 23-105-18 was mentioned as a possible solution, but owners were told it had expired. One owner was stopped by law enforcement for defective headlamps.
The third set of failures involves failed or intermittent headlights—one owner's passenger-side headlight failed repeatedly due to wiring and computer issues; another experienced low-beam failures at various speeds. A third reported dashboard light flickering that occurs during motion, at rest, and even with the engine off. One complaint also noted water entering through the third brake light, causing interior water damage and a shattered bulb at 25,000 miles.
Failure modes owners describe
Inadequate low-beam output
Low beams produce insufficient illumination and appear yellowish, making safe night driving difficult. Owners consistently resort to high beams. Some owners report dealer readjustment attempts were ineffective.
When: Across mileage range; some reports as early as 14,500 miles
Symptoms owners cite: Excessive reliance on high beams; Poor visibility at night; Yellowish light color; Underpowered lighting output; Inadequate illumination for road conditions
Repairs/costs cited: Dealer readjustment attempted but ineffective; no successful repair reported
Moisture and condensation in headlight housings
Water condenses inside sealed headlight assemblies, creating fogging and reducing light transmission. Moisture persists rather than clearing on its own as manufacturer claims it should. Affects both single and projector-style headlights. Occurs repeatedly even after dealership replacement.
When: Reported across vehicle lifespan, including shortly after replacement
Symptoms owners cite: Visible condensation/fogging inside lens; Reduced brightness from moisture; Fog-like effect in sealed beam areas; Persistent moisture that does not dissipate; Dimmer-than-expected light output
Repairs/costs cited: Dealership replacement of headlight units performed in at least one case, but new units developed same issue
Recalls/TSBs owners mention: TSB 23-105-18 mentioned; owner informed TSB had expired and vehicle was not under recall. Manufacturer told one owner moisture should dissipate within days.
Headlight electrical failure
Individual headlight units fail to operate or burn out repeatedly. One owner reports passenger-side headlight failure attributed to inferior wiring and computer problems confirmed by dealership and independent mechanics. Another reports low-beam failures on multiple occasions.
When: Approximately 14,500 miles; repeated failures reported
Symptoms owners cite: Headlights fail to illuminate; Bulbs burn out repeatedly during driving; Passenger-side unit non-functional; No warning light for failure
Repairs/costs cited: Owner states dealership and independent mechanics could not provide affordable repair. One complaint mentions poor electrical system design as root cause.
Dashboard and instrument light flickering
Dashboard and instrument lights flicker intermittently, occurring while vehicle is in motion, stopped, and even with engine shut off. One owner reports this alongside headlight and tire pressure system warnings.
When: Described as ongoing over 4-month period
Symptoms owners cite: Dashboard light flickering; Instrument light flickering; Occurs at various vehicle states (moving, stopped, engine off); Difficult to drive due to flickering distraction
Water intrusion through third brake light
Water enters vehicle interior through the third brake light (center high-mounted brake light), causing interior water damage and mold. Condensation appeared on inside of front windshield; standing water found under rear seat.
When: Approximately 25,000 miles
Symptoms owners cite: Condensation on interior windshield; Standing water under rear seat; Mold smell inside vehicle; Shattered third brake light bulb; Water intrusion into cabin
Repairs/costs cited: Vehicle repaired after investigation (note added 02/12/16)
