What stands out
No new NHTSA visibility complaint has been filed on this vehicle in over 14 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 visibility 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 communicates to the technician the need to inspect the induction system for potential icing issues in very cold ambient temperatures. To allow the ice to melt so that it can be drained from the related components. That any of the listed DTC's may set with or without poor engine performance.

The failure pattern owners describe
Owners report two dominant visibility problems in the 2005 GMC Envoy: defective windshields and spontaneous rear hatch-window failure.
Windshield complaints center on optical distortion. Multiple owners describe the windshield as wavy, out of focus, and distorted, causing severe eye strain, headaches, dizziness, and nausea even on short drives. One owner reports the dealership acknowledged the defect and stopped replacing windshields due to a memo stating all are defective. Another describes a windshield that cracked in the exact pattern of the defroster outlet, suggesting localized heat concentration.
Rear hatch-window failures are more dangerous and widespread. Owners report spontaneous shattering while parked, while closing the hatch, or during normal operation—sometimes repeatedly on the same vehicle within days. One owner's rear window exploded twice in two days; another had it fail while a passenger sat in the back seat. Several owners note bracket failures; one describes a bracket breaking and causing the window to shatter with glass scattered 20 feet away. One owner was injured with cuts to the back when the window exploded overhead.
Other visibility-related failures include power window motors failing (both front windows), wipers stopping mid-operation during rain, and a rear glass door separating at hinges. One complaint involves memory seats not recalling with the remote unlock, reducing convenience. Dealers deny knowledge of systematic issues while owners cite online forums documenting similar failures across multiple model years.

Failure modes owners describe
Windshield optical distortion
Windshield exhibits wavy, out-of-focus, and distorted optical properties causing severe eye strain, headaches, dizziness, and nausea during driving. Condition worsens in bright sunlight. One owner reports dealership acknowledged all windshields are defective and stopped replacing them per internal memo. Replacement units exhibit identical defect.
When: Present from new; complaint filed within first year of ownership
Symptoms owners cite: Inability to focus clearly through windshield; Extreme eye strain and eye pain; Migraine headaches; Dizziness and nausea; Wavy and distorted vision; Worsening in bright/sunny conditions
Repairs/costs cited: Dealership replaced windshield with unit from another dealership; replacement exhibits identical defect. Owners cite cost of replacement windshields but focus on optical rather than replacement costs.
Recalls/TSBs owners mention: Dealership memo states all 2005 Envoy windshields are defective; dealership ceased replacement attempts. No field service reps available. Manufacturer has not addressed.
Rear hatch-window spontaneous shattering
Rear hatch window shatters without apparent cause—while vehicle is parked, while closing the hatch, or during normal operation. Shattering is explosive, scattering glass 20+ feet. Failure occurs repeatedly on some vehicles within days. One owner experienced failure while closing hatch immediately after replacement. Owners report finding online forums documenting the same failure across multiple Envoy model years.
When: Early use through mid-life; mileage ranges 0–104,751 miles; one failure at 40,000 miles
Symptoms owners cite: Spontaneous window shattering while parked; Window shattering while closing hatch; Loud explosive pop or bang; Glass scattered inside and outside vehicle, sometimes 20+ feet away; Recurrent failures on same vehicle; Failure in various weather conditions
Repairs/costs cited: Glass replacement costs $937–$1500 per owners. One owner paid $200 insurance deductible; another paid $1500 out of pocket. Warranty companies often deny claims citing glass exclusions. One owner's repair was covered by manufacturer at $1500.
Recalls/TSBs owners mention: Dealer denies knowledge of systematic issue despite owner research showing multiple online reports and forums. One manufacturer covered repair cost ($1500); others refuse. No recall issued. Warranty companies deny glass coverage.
Rear hatch-window bracket failure
Bracket securing rear hatch window detaches or breaks, leading to window shattering. Owner reports bracket snapped in two, causing window to explode. Glass fragments ejected up to 20 feet away. Describes as design flaw reported by others nationwide.
When: Occurs on used vehicle; timeline not specified
Symptoms owners cite: Bracket detachment; Bracket fracture/breakage; Spontaneous window shattering following bracket failure; Explosive glass ejection
Repairs/costs cited: Cost mentioned as $1500 for glass door replacement. Owner sustained cuts from glass.
Recalls/TSBs owners mention: Warranty refuses coverage, citing glass-only exclusion; does not acknowledge bracket as root cause.
Windshield crack from defroster outlet
Windshield cracked in the exact shape and location of the central defroster outlet when defroster was activated on a cold evening. Owner reports heat concentration from single-exit defroster design is hazardous.
When: Five minutes after defroster activation on cold evening
Symptoms owners cite: Large crack in windshield; Crack pattern matches defroster outlet shape
Power window motor failure (front windows)
Both front power windows fail during normal operation. One window stuck in down position; other window falls from vibration while driving and owner must manually push it up. Failure occurred while operating windows normally via button control.
When: Timeline not specified
Symptoms owners cite: Window will not operate via button; Window stuck in down position; Window falls during driving from vibrations; Manual push-up required while driving
Repairs/costs cited: Owner notes replacement cost is high but does not specify amount. Repair not yet completed.

When: At 129,000 miles
Symptoms owners cite: Window will not move when control button is pressed; Window stuck in position
Repairs/costs cited: Vehicle not repaired.
Recalls/TSBs owners mention: Manufacturer notified; complaint filed.
Windshield wiper failure during rain
Windshield wipers stopped working while vehicle was driving in rain after being switched to slowest mode. Caused poor visibility during active rainfall.
When: Recently after purchase with approximately 6,000 miles on odometer
Symptoms owners cite: Wipers stop working mid-operation; Failure occurs in rain; Loss of visibility during rainfall
Repairs/costs cited: Not yet repaired.
Recalls/TSBs owners mention: Warranty company advised coverage may not apply.
Rear glass door separation at hinges
Rear glass door came unglued at hinges, damaging the struts and nearly falling on owner. Door reattached with adhesive but came loose again, creating repeated hazard of door falling.
When: Timeline not specified
Symptoms owners cite: Glass door separation from hinge attachment; Damage to hatch struts; Door coming loose after repair attempt
Repairs/costs cited: Dealer suggested glass door replacement at $1500. Repair attempted using adhesive/glue; failure recurred.
Headlamp Driver Module (HDM) failure and overheating
Low beam relay and Headlamp Driver Module burned out and overheated, melting fan relay and fusing relays together. Caused headlamp and daytime running lights to fail. Same defect triggered recalls for 2006 and 2007 Envoys but not this 2005 model.
When: First failure around 4/9/2015; recurring issue
Symptoms owners cite: Low beam relay burnout; Headlamp Driver Module overheating; Fan relay melted; Multiple relays fused together; Headlamps fail to illuminate; Daytime running lights fail to illuminate

The rear windshield of my 2005 GMC envoy xl exploded for no apparent reason today. I lifted the full hatch (not just the window section) to place items in the back that I had purchased at home depot. I placed a can of paint, one bag, and a bag of sand in the back - nothing that was near the glass of the hatch. I then closed the hatch with enough force for it to close securely, but not with…
Rear windshield/back window shattered on it's own while parked in parking lot. Couldn't figure out why or what had caused this to happen. Took the vehicle to shop for windshield to be replaced, and when I got in the car to leave the shop the rear windshield shattered again. My daughter was in the back seat at the time and this scared the crap out of both of us. The shop could not believe this…
