severe 61 complaints filed with NHTSA · avg repair $350 · see visibility across all vehicles →
Of the 4 model years of Chevrolet Trailblazer we track for visibility problems, this one carries the most owner complaints on file — 61.
Owners have filed 61 visibility 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.
The failure pattern owners describe
Buyer takeaway: The 2006 Trailblazer has serious, recurring visibility and electrical defects that GM has not adequately addressed. Uncontrolled wiper and washer spray, rear window glass explosions, power window failures with burnt wiring, and seat shifting are the main complaints—some require removing fuses to stop, and repair costs are high with failures recurring within weeks.
Owners of the 2006 Chevrolet Trailblazer report multiple chronic visibility system failures. Most common is windshield wipers and washer fluid activating without user input, particularly when starting the vehicle or while driving. Owners say the system ignores the OFF switch, sprays fluid at such high pressure that wipers cannot keep pace, and cannot be shut off except by removing the fuse. This occurs across the mileage range from 60,000 to 135,000 miles. GM denies the problem exists despite issuing Service Bulletin 040843005B, and claims earlier recalls for 2002–2003 models do not apply to 2006 MY vehicles—even though owners report the identical failure.
Rear liftgate glass shatters spontaneously, sometimes while parked with the hatch open and sometimes when simply closing the door. Glass breaks into tiny sharp pieces that rain down on occupants. Replacement costs nearly $1,000 with labor; one owner reported the glass exploded again three weeks after replacement.
Power window electrical modules and switches fail frequently, with some showing melted wiring and burning odor in the driver-side door. Windows stop working, door locks jam, and mirrors move on their own. Driver seats shift backward while driving, reducing brake pedal reach and causing near-collision incidents. Tall drivers (6+ feet) report the rearview mirror blocks forward visibility through the front windshield with no seat adjustment remedy. Wiper speed control malfunctions also occur, leaving drivers unable to set appropriate wiper speeds in rain.

Failure modes owners describe
Windshield wipers and washer fluid activate uncontrollably
Wipers and washer fluid spray activate without user input, often when the vehicle starts or while driving. Owners report the wipers turn on even with the switch in the OFF position, spray continuously at uncontrollable rates, and cannot be shut off without removing the fuse. The fluid sprays with such force that visibility is severely impaired, making the vehicle dangerous to operate.
When: 60,000–135,000 miles; incidents occurring from shortly after purchase through later model years
Symptoms owners cite: Wipers activate when starting the vehicle with switch off; Washer fluid sprays continuously at high pressure; Wipers operate at only high speed, ignoring speed control settings; Wipers will not turn off unless fuse is removed; Fluid sprays so heavily that wipers cannot keep pace, obscuring visibility completely; Wipers come on randomly during driving at any speed or road condition; Fluid sprays without wipers operating, or vice versa
Repairs/costs cited: Owners report wiper motor replacement ($300), wiper assembly replacement, multi-function switch replacement, and wiper motor module assembly replacement. Repairs are temporary; failures recur within weeks to months. One owner noted Technical Service Bulletin 040843005B. Disconnecting washer fluid reservoir or removing fuse are temporary workarounds.
Recalls/TSBs owners mention: GM denies problem exists and claims no recalls apply to 2003–2006 models despite prior recalls on 2002–2003 models for the same issue. Service Bulletin 040843005B issued but problem persists in later model years. Recall NHTSA Campaign 04V046000 (2002–2003 models) does not cover 2006 model year.
Rear liftgate glass explodes
Rear liftgate window glass spontaneously shatters while the vehicle is parked or when the liftgate is being closed. Glass breaks into tiny sharp pieces and rains down on occupants with enough force to cause lacerations. Owners report the vehicle has not been in any collision and nothing has struck the window.
When: Before 60,320 miles
Symptoms owners cite: Rear window glass explodes into tiny pieces; Glass shatters when liftgate is closed with moderate force; Glass shatters while vehicle is parked with liftgate open; Owners report seeing other Trailblazers with missing rear window components, suggesting widespread occurrence
Repairs/costs cited: Replacement glass costs nearly $1000 including labor. One owner reported glass shattered again three weeks after replacement during testing. Another owner's glass exploded again immediately upon closing the door at the repair shop.
Recalls/TSBs owners mention: No recalls issued. GM referred complaint to dealer; dealer refused assistance citing vehicle out of warranty. Technical Service Bulletin 070852003 exists but no recalls. Manufacturer did not offer assistance or assume liability.
Power window switches and electrical modules fail
Door power window switches, electrical control modules, and wiring fail, preventing windows from opening or closing. Owners also report related failures in door locks, mirrors, and heated seat controls. Some cases involve burning odor and melted wiring in the driver-side door area.
When: 62,000–120,000 miles
Symptoms owners cite: Windows will not open or close; Rear passenger window locks and closes without warning; Front driver and passenger side door mirrors move independently; Door locks fail to operate; Burning smell from driver-side door; Window switch melted or showing signs of heat damage; Wiring visibly melted inside door panel; Master window switch fails
Repairs/costs cited: Driver-side door control module replacement required. Driver-side door window switch and side panel replacement. Window electrical module replacement. Costs not specified by owners but repair requires door disassembly. One owner's window switch melted at 66,523 miles; dealer replaced the electrical module.
Recalls/TSBs owners mention: Recall NHTSA Campaign 12V406000 (Electrical System, Visibility: Power Window Devices and Controls) exists but many VINs do not qualify. Manufacturer advised some owners that VINs failed to qualify despite recall notification being sent. Some owners received recall notification but parts were unavailable for extended periods with no estimated repair date.
Seat position shifts unpredictably while driving
Driver or passenger seat moves backward or forward on its own while the vehicle is in motion, without owner input. Owners report the seat moving suddenly while driving, causing loss of brake pedal reach and near-collision incidents.
When: Mileage not specified; occurs intermittently during driving
Symptoms owners cite: Seat relocates backward while driving in gear; Driver loses reach to brake pedal; Wife unable to step on brake to avoid collision; Driver-side mirror also changes position independently at times when set to neutral
Repairs/costs cited: No repairs reported; GM declined investigation. One mechanic anecdotally suggested filing complaint after a crash rather than before.
Recalls/TSBs owners mention: GM not willing to investigate electric seat position failure.
Front windshield obstructed by rearview mirror in tall drivers
The rearview mirror placement blocks the forward visibility of the front windshield for drivers over 6 feet tall. Seat adjustments do not provide adequate compensation to achieve a full panoramic view of traffic ahead.
When: Shortly after purchase
Symptoms owners cite: Rearview mirror completely blocks vision of approaching vehicles; Near-collision at stop sign due to blocked visibility; Seat cannot be lowered enough to clear the obstruction and achieve full panoramic view
Repairs/costs cited: No permanent repair available; owner attempted seat adjustments without success.
Recalls/TSBs owners mention: GM representative claimed no complaints or accidents have been attributed to this condition and stated the 2006 Trailblazer meets all NHTSA standards.
Windshield wiper speed and function malfunctions
Wipers fail to operate at the selected speed setting or fail to operate predictably. Wipers may work on high speed only, operate intermittently at wrong speeds, or stop mid-stroke and not resume, leaving the windshield partially wiped.
When: Mileage varies; issues begin spontaneously during driving
Symptoms owners cite: On low speed setting, wipers may or may not activate; On high speed, wipers work intermittently or operate at low speed instead; Wipers slow or fail to operate at all; Wipers stop in the middle of the windshield and do not continue; Dry wiping causes scratches and marks on windshield; Windshield becomes obscured when driver needs wiper function most
Repairs/costs cited: Wiper motor replacement ($300) reported with no lasting resolution. Scratching and marking of windshield from dry wiping.
Recalls/TSBs owners mention: No manufacturer response documented for this specific malfunction.
Smoke and electrical fire in driver-side door area
Smoke and burning odor emit from the driver-side control panel and door area, accompanied by window switch failure and melted wiring. One case involved all lights on the instrument panel illuminating and vehicle stalling.
When: 60,000–106,000 miles
Symptoms owners cite: Burning smell coming from driver-side door; Smoke emits from driver-side control panel while driving; Window switch fails to function; Door locks fail to function; Melted wires visible inside door panel; All instrument panel lights illuminate; Vehicle stalls
Repairs/costs cited: Door and window switch console removal confirms melted wires. Window motor and cables described as burned out. No owner reported repair completion.
Recalls/TSBs owners mention: Manufacturer did not offer assistance since vehicles were not included in NHTSA Campaign 12V406000 or any applicable recall.
