Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering body 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.

Some customers may comment that one or more of their vehicle's underbody components are showing some form of corrosion. This corrosion may be red in appearance (rust) if the component is steel, forged iron or cast iron. This corrosion may also be grey or white in color if the component is constructed of an aluminum alloy.

The failure pattern owners describe
Owners of 2005 GMC Envoy vehicles describe a pattern of rear-door and hatch failures that create safety hazards. The most frequent complaint involves rear door latch assemblies that corrode internally and fail to hold doors closed — leaving doors unable to latch or swinging open during driving. One owner had both rear latches fail within two hours in 2007 and had to secure the doors with rope; the dealer replaced both assemblies, but the identical part failed again three years later. Another owner found heavy rust and corrosion inside the latch and striker, requiring repeated disassembly, cleaning, and re-tightening to keep doors functional temporarily.
The rear hatch presents its own set of problems. The plastic cover and center high-mounted stop lamp assembly (CHMSL) are bonded with double-sided adhesive tape that fails repeatedly at highway speeds, causing the cover to break and hang down or detach completely — one owner reports this happening three times on the same vehicle. GMC issued a technical service bulletin (TSB #01-08-66-007C) for re-taping the applique, but the fix does not hold. One owner also reported the rear hatch glass exploding spontaneously overnight while the vehicle sat parked.
Additionally, a 2005 Envoy exhibited uncontrolled door unlocking and actuation across all doors due to water intrusion and corrosion in the master switch assembly, making doors swing open randomly while driving. The hatch and rear-door handle mechanisms deteriorate with age, requiring repeated dealer service.
No comprehensive recall or permanent repair design fix has been offered for these issues.
Failure modes owners describe
Rear hatch plastic cover/CHMSL applique detachment
Double-sided adhesive tape bonding the plastic cover and center high-mount stop lamp (CHMSL) applique to the rear liftgate glass fails, causing the cover to break or separate from the vehicle during driving at highway speeds.
When: First occurrence 2006, second occurrence 2008 at 55 mph, third occurrence May 2010 at 55 mph; low mileage (31,192 miles noted)
Symptoms owners cite: Rattling of rear hatch plastic at highway speeds; Plastic cover breaks and hangs down over rear window; Entire piece (3 ft 10 in × 10 in) becomes detached and falls off vehicle; CHMSL lamp attachment point affected
Repairs/costs cited: GMC local dealer performed re-taping of CHMSL applique in 2006 and 2008; owner notes adhesive failure persists. GMC internally documented as TSB #01-08-66-007C (Center High-Mount Stop Lamp Applique Loose, Re-tape Applique) dated Aug 27, 2007.
Recalls/TSBs owners mention: TSB #01-08-66-007C issued for re-taping; GMC dealer stated owner should not use hatch in winter and advised against driving over 50 mph (described as inadequate by owner)
Door lock master switch failure — water intrusion and corrosion
Driver's side door master switch fails due to water intrusion into the circuit, causing internal rust and pole corrosion. Affects all doors (front and rear, both sides) and rear hatch latch mechanism.
When: Unknown mileage on initial 2005 Envoy complaint; similar recall (15V599000) applies to 2006-2007 model years
Symptoms owners cite: Doors unlock independently while driving; Door knob actuates up and down continuously; Doors swing open while vehicle is being driven or reversing; Both driver's and passenger's side front and rear doors affected; Rear door and hatch also affected; Continuous door chime alarm (no warning lights)
Repairs/costs cited: Independent mechanic diagnosed water intrusion causing rusted poles in driver's side door master switch; switch replacement recommended but not performed by owner
Recalls/TSBs owners mention: GMC informed owner that 2005 model year was not covered under NHTSA Campaign 15V599000 (which applied to 2006-2007 only); no assistance offered
Rear door latch assembly failure
Rear door latch assemblies fail to hold or properly secure rear doors closed. Internal corrosion and rust debris indicate moisture intrusion and degradation of the latch mechanism. Doors cannot be latched closed and remain partially open.
When: June 2007 (initial failure both rear doors), October 2010 (left rear door repeated failure); 80,000 miles noted on one vehicle
Symptoms owners cite: Unable to close either rear door; Left rear door fails to latch on two separate occasions; Right rear door exhibits same problem at 80,000 miles; Door latch striker corroded and deteriorated; Excessive rust and corrosion on latch assembly when disassembled; Door flies open while driving around corners or on highway
Repairs/costs cited: Dealer replaced both rear door lock assemblies in 2007 ($125 labor); left rear door lock assembly replaced again in October 2010 ($295.35); owner reports replacement parts are identical to failed originals and fail again; temporary fixes included tying doors and using duct tape or bungy cords
Recalls/TSBs owners mention: No recall issued; dealer performs replacement under warranty/service but with same faulty parts
Rear hatch glass spontaneous failure
Rear hatch glass explodes or shatters while vehicle is parked and stationary, with no external impact or cause identified.
When: Occurred overnight while vehicle parked in garage for over 12 hours
Symptoms owners cite: Rear hatch glass explodes spontaneously; Glass fragments everywhere inside cargo area; Vehicle had not been moved for over 12 hours prior to failure
Repairs/costs cited: Glass replacement required; owner notes this is reported as a common issue with these vehicles
Rear hatch/door opening mechanism and handle failure
Interior and external mechanisms for opening and securing the rear hatch and door handles degrade and fail repeatedly. Ballasts and piston assemblies fail due to repeated use.
When: Chronic issue reported over 3 years with repeated dealer visits
Symptoms owners cite: Back door handles fail; Interior mechanisms fail; Hatch pistons and ballasts fail; Repeated trips to dealer with same problem recurring; Problem not resolved after multiple repair attempts
Repairs/costs cited: Multiple dealer service visits over 3-year period; repairs not holding
