What stands out
Owners have filed 27 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 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 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
The 2006 Pontiac Grand Prix has a widespread low-beam headlight problem. Owners describe lights cutting out without warning—sometimes for seconds, sometimes for hours—while driving at speeds from 35 to 75 mph. High beams and parking lights stay on, but the low beams won't respond to manual switch activation. Lights may restart on their own, or require a vehicle restart or switch cycling to come back. At least two owners report lights that eventually fail completely.
The failure strikes across the mileage range—from 40,000 miles to 290,000 miles. Some owners note it happens more often in warm weather and rain. One owner's lights recurred after replacing the steering column and multifunction switch; another replaced the switch twice in less than two years.
Owners point to relay #35 (low-beam relay) as a likely culprit based on online research, but replacing it hasn't solved the problem consistently. Several mention fuse-box fires reported online after relay replacement. Dealers often can't replicate or diagnose the issue. GM has issued a coverage notice limited to vehicles under 150,000 miles, leaving higher-mileage owners stuck. The safety risk is obvious: losing headlights on a dark highway at speed is a crash hazard.

Failure modes owners describe
Low-beam headlight intermittent failure / complete cutout
Low-beam headlights cut out without warning during day or night driving at various speeds. High beams and parking lights remain functional. Lights may return on their own after minutes to hours, or require vehicle restart or switch manipulation to restore. Some owners report lights eventually fail completely and won't illuminate at all.
When: Occurs across mileage range: 40,000 miles to 290,000 miles. One owner reported onset after 2 years of ownership with only 53,000 miles; another on a vehicle with nearly 199,000 miles. Some owners note increased frequency in warm weather and rain.
Symptoms owners cite: Low beams cut out intermittently while driving, high beams still work; Lights fail to respond to manual switch activation when problem occurs; Lights stay off for 15 minutes to 30+ minutes, then self-restore; Some lights won't come back on at all after failure; Flickering on and off while driving at night; Automatic daytime running lights fail to engage on cold start; Headlamp warning indicator illuminates on dashboard when lights fail
Codes mentioned: Relay #35 (low-beam relay) cited by multiple owners as suspect, HDM relay replacement attempted by owners without resolution
Repairs/costs cited: Owners report replacing: low-beam relay #35 ($35–$50 part); headlight bulbs; multifunction/dimmer switches (some replaced twice); head lamp/lighting module; steering column; complete wiring checks and ground inspections. One owner references GM part #15016745 (available $35–$50, but GM replacement part costs ~$300). Repairs sometimes work briefly before failure recurs. Dealers often cannot diagnose the issue when vehicle is tested.
Recalls/TSBs owners mention: GM issued notice covering replacement for vehicles under 150,000 miles; owners over that mileage are not covered. Mentioned online references to recall #14291, though owner could not locate it in official database. One owner reports fuse box fire risk has been noted online by many posters. Reports of vehicle frame/fuse box becoming extremely hot after being parked.
Daytime running lights / automatic light system malfunction
Automatic daytime running lights fail to engage automatically, or drivers become confused whether lights are actually on. Related to broader low-beam failures affecting night visibility.
When: Occurs on cold starts and intermittently during operation.
Symptoms owners cite: Automatic lights don't engage on cold start; Confusion about whether daytime running lights are active, creating visibility risk
High-beam interference / failure on turn signal engagement
One owner reported high beams work intermittently and completely fail when turn signal/blinker is engaged, suggesting a control circuit or relay conflict.
When: Occurred at 70 mph on highway.
Symptoms owners cite: High beams work intermittently during normal driving; High beams fail completely when blinkers/turn signals are engaged
Repairs/costs cited: Dealer unable to diagnose failure.
Recalls/TSBs owners mention: Manufacturer notified; no resolution documented.

Common questions
How serious is the lighting problem on the 2006 Pontiac Grand Prix?
It's a documented issue but not catastrophic. 27 complaints have been filed. Repairs average $250 and most owners catch it before it causes a breakdown.
At what mileage does the lighting typically fail?
Across the 19 complaints that reported odometer mileage, most lighting failures cluster between 60,000 and 140,000 miles, with the median around 85,000. A quarter of owners report trouble before 60,000; a quarter make it past 140,000. 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 $250 for lighting 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 lighting?
No active recalls currently cover lighting 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.
