What stands out
All 2 active visibility recalls on this vehicle land at critical or severe — none classified moderate.
No new NHTSA visibility complaint has been filed on this vehicle in over 13 years — the issue may be aging out of the active population.
General Motors LLC (GM) is recalling certain model year 2005-2007 SAAB 9-7x; 2006 Chevrolet Trailblazer EXT and GMC Envoy XL; and 2006-2007 Chevrolet Trailblazer, GMC Envoy, Buick Rainier and Isuzu Ascender vehicles
A short in the circuit board could lead to a fire, increasing the risk of personal injury. A fire could occur even while the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been made.
Fix: GM will notify owners, and dealers will inspect the part number on the door module, and install a new door module if necessary, free of charge. Parts for the remedy are not currently available. An interim letter was mailed to owners in August 2014. A second owner letter will be mailed when parts are available.

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.

The failure pattern owners describe
Power window control systems are the dominant issue in these 31 complaints. Drivers' side master window switches overheat, melt, and smoke, with burning odors preceding failures in at least ten separate narratives. Three owners report fire or charring. Switches get stuck then fail completely. Control modules degrade, disabling not just windows but door locks, memory seats, and heated seats. Repair estimates run $300 for module replacement.
NHTSA Campaign 12V406000 was issued for power window defects, but owners waited months for parts availability—some reported three to four months with no remedy forthcoming. Multiple owners report their VINs were excluded from recalls despite having identical failures. One owner's recall repair failed when rainwater entered the door module during normal use, proving the fix inadequate against liquid intrusion.
Windshields crack without impact at various mileages. One owner observed three Trailblazers parked together, all with identical cracking patterns. Another owner reported the same spontaneous cracking on a 2006 Cobalt. One rear hatch window shattered while closing normally. Headlights fail intermittently or completely at night; one owner drove 55 mph before lights died. GM's recall 14291 excludes some VINs despite matching failures. Windshield seals separate, causing wind noise. Repair delays, parts shortages, and dealer refusals to service are consistent complaints throughout.

Failure modes owners describe
Power window switch and control module overheating/melting with fire risk
Driver's side (and sometimes both front) power window switches and control modules overheat, melt, and emit burning odors or smoke. In severe cases, the door console or control box catches fire or shows significant char marks. The electrical system degrades to the point where windows, door locks, memory seat controls, and heated seat controls fail simultaneously.
When: 42,000 to 119,000 miles; reported at various stages of vehicle use, including while actively operating windows or while parked
Symptoms owners cite: Burning odor from driver's side door or window area; Smoke or visible fire from door panel or window switch; Power window switch becomes extremely hot during operation; Master window switch gets stuck in down position then stops responding; Door console or control box shows melted or burnt material

Windshield cracking without impact
Windshield develops cracks spontaneously while driving with no impact, impact noise, stone strike, or external cause reported. Owners observed the same pattern of cracking on multiple Trailblazers parked together. One owner also reported cracking on a 2006 Chevrolet Cobalt with the same symptom pattern.
When: At various mileages; reported at 77,000 and 115,000 miles; one case occurred twice on the same vehicle over a two-year span
Symptoms owners cite: Crack develops across windshield while driving; No external impact or impact noise preceding crack; Cracks appear in the same location across multiple vehicles; Rear windshield shattered while driving at 40 mph with no reported cause
Repairs/costs cited: No repairs documented; one insurance claim filed; no manufacturer action taken
Recalls/TSBs owners mention: Manufacturer notified in at least one case; no response documented
Rear hatch window shattering

When: Occurred while closing hatch during luggage loading; failure mileage not specified
Symptoms owners cite: Rear hatch window shatters when hatch is closed; No contact with glass confirmed by owner
Repairs/costs cited: Insurance claim filed; Chevrolet contacted with service request but took no action
Recalls/TSBs owners mention: Service request received (# 71-626176152) but no action taken by Chevrolet
Headlight failure (intermittent and complete loss)
Headlights fail to illuminate at night. Failures are intermittent, going on and off, or complete with lights not responding to automatic or manual controls. Owner reported cycling vehicle on and off temporarily restores function. One owner experienced headlight failure at 55 mph on a four-lane road.
When: Mileage not documented in narratives; failures occur at night during driving
Symptoms owners cite: Headlights will not come on (automatic or manual mode); Headlights go off while driving; Lights respond intermittently (go in and out); High beams required to drive home after low beams failed
Repairs/costs cited: One repair cost $80; no GM reimbursement provided despite owner request
Recalls/TSBs owners mention: GM Recall 14291 (NHTSA ID 14V7550) exists but owner's VIN not covered despite identical failure; GM refused reimbursement claim; one owner notes other dozens of complaints to NHTSA for same issue
Windshield seal separation and wind noise
Windshield rubber seal separates from frame, allowing wind noise to enter the vehicle. Windshield appears loose or seal did not adhere properly. One recall noted for 2005 model; unclear if issue carries over to 2007.
When: Mileage not documented
Symptoms owners cite: Wind noise from top portion of windshield (passenger to driver side); Windshield appears loose; Sealant appears not to have adhered
Repairs/costs cited: Rubber seal replaced in one case; no other repairs documented

Window control module water intrusion damage (post-recall)
After recall repair under NHTSA 12V406000 was performed, water entered the door module during a light rain with windows cracked, causing all switches to stop functioning. Dealer stated the recall fix was not designed to protect against liquid water ingress, only ambient moisture.
When: Occurred after recall repair was completed; subsequent to rain event
Symptoms owners cite: All switches stopped working after water entered door module; Failure triggered by windows left cracked during light rain
Repairs/costs cited: No repair documented post-water intrusion
Recalls/TSBs owners mention: Dealer informed owner that recall fix was not intended to protect against liquid water, only ambient moisture
