What stands out
No new NHTSA lighting complaint has been filed on this vehicle in over 3 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.
This Preliminary Information communication provides information to the technician about vehicles that have a Service Engine Soon Malfunction Indicator Lamp on. Technician will find Diagnostic Trouble Code P2097 or P2099. Technician will need to perform an injector balance or Active Fuel Injector Tester prior to going further. Technician will also need to check for a small leak in the exhaust if published Service Information diagnostics does not lead to a resolution.

The failure pattern owners describe
Owners describe the 2014 Acadia's headlights as fundamentally weak, with a sharp cutoff that doesn't light the road far enough ahead or to the sides. One owner felt like driving with a dark hood over their eyes, and another couldn't safely navigate hills and curves at night even with fog lights on. The problem isn't worn-out bulbs—owners have replaced them multiple times with different brands, yet the dimness persists.
Some headlights fail entirely without warning, leaving drivers in the dark mid-drive with only fog lights as backup. Mechanics check the fuses, computer, and battery and find nothing wrong, yet the lights stay dead for weeks or months.
Rear tail lights are leaking. Water gets inside the sealed assemblies, condensation fogs the lens, and moisture shorts out the bulbs. Dealers have replaced entire light kits—sometimes twice—but the replacements develop the same problem. GM responded by refusing to cover water damage under warranty. Turn signal assemblies are also failing, and at least one critical part (GM 13582912) is unavailable at dealerships and discontinued at parts suppliers. Replacement light assemblies run over $300 each.

Failure modes owners describe
Dim or inadequate headlight output
Owners report headlights do not illuminate the road sufficiently, with limited range and a distinct cutoff of light at the top of the beam pattern that restricts forward visibility.
When: Varies; some reported at 135,000 miles; timing not specified in others
Symptoms owners cite: Headlights do not shine far enough to see road ahead or to each side when turning; Dark hood appearance over upper part of vision; beam bounces while traveling; Distinct cutoff of light at top of illuminated area; Fog lights do not compensate adequately; Low beam and high beam both dim; Cannot see upcoming road conditions, curves, elevation, animals, or hazards
Repairs/costs cited: Owner replaced bulbs multiple times with different brands; bulbs failed prematurely. Independent mechanic unable to determine cause.
Headlight complete failure
Headlights stop working entirely, with no illumination from either low or high beam, though fog lights and LED running lights remain functional. No electrical faults detected in diagnostics.
When: One incident at 9 PM on highway; another occurred with no prior warning; third after 2 months of ownership
Symptoms owners cite: Headlights abruptly stopped working; Auto running lights position does not activate headlights; Low beam and high beam inoperative; Fog lights and LED running lights work normally; No warning before failure
Repairs/costs cited: Multiple mechanics found no problems with headlights, fuses, computer, or battery; no lamp replacement needed. No solution found after two months.
Rear tail light water intrusion and condensation
Tail light lens assemblies allow water to enter, causing internal condensation and water droplets that cloud the lens and reduce stop light visibility. Affects up to 50% of lens coverage.
When: Occurred within warranty period; second incident noted on customer satisfaction repair
Symptoms owners cite: Rear tail light lens clouds up with condensation and water droplets; Stop light visibility affected by internal moisture; Condensation does not clear adequately even after 16 miles of driving or overnight outdoor storage
Repairs/costs cited: Dealer replaced all tail light assemblies on first warranty claim and left rear assembly only on second customer satisfaction claim. Replacement assemblies also developed condensation.
Recalls/TSBs owners mention: GM issued letter stating warranty claims will not be honored for water condensation on tail light lens
Turn signal failure
Turn signals fail to operate properly or stop working entirely. One owner reports left rear turn signal with GM part number 13582912 unavailable at multiple dealers.
When: Occurred after several years of ownership; specific mileage not stated for most cases
Symptoms owners cite: Turn signals fail to operate while engaging turn signal lever; Turn signal sound occasionally inoperative; Left rear turn signal not working
Repairs/costs cited: GM part 13582912 unavailable at multiple GM dealers, on order with no confirmed delivery date. Some parts stores indicate part is discontinued. No aftermarket substitutes available.
Recalls/TSBs owners mention: No manufacturer response documented
Bulb seal failure in rear light assemblies
Seals in rear light kit covers deteriorate, allowing water intrusion. Water accumulates inside and shorts out bulbs, causing rear lights to fail partially or completely.
When: Multiple incidents; specific timing not always stated
Symptoms owners cite: Water collects inside light assembly; Bulbs short out from water intrusion; Tail lights, brake lights, or blinkers fail to work properly
Repairs/costs cited: Complete light assemblies cost over $300 each. Replacement assemblies may be in short supply.
Recalls/TSBs owners mention: No official response documented; owner notes that parts supply cannot keep up with demand and GMC has a known defect

Head lights quit working. I had two children in the car with me and it was night time, and I could’ve collided with another car. This just happened tonight, so I have not taken it to the dealer yet or a certified mechanic. There were no warnings of any kind before this happened.
2014 GMC acadia headlights do not shine out far enough to see the road ahead or to each side when turning. I feel like I have a dark hood over the top part of my eyes and this hood "bounces" as you travel--very distracting, irritating, and unsafe. When driving at night, I always have my fog lights on, but even that does not help much. When driving on a hilly, curvy road, it is impossible to see…
Two separate warranty claims. Dealer did replace all tail light assemblies- once on normal warranty claim, the second incident (lhs only) on customer satisfaction basis. Issue> rear tail light lens clouds up with condensation / water to the point that stop light visibility is affected. Approx 50% of the lens is covered internally with water droplets and condensation potentially violating…
