Service bulletin - Certain Honda vehicles operated in areas known for high absolute humidity and high heat may contain a front passenger?s airbag that, over time, may be affected by exposure to the humidity, which could produce excessive internal pressure upon deployment. If an affected airbag deploys, the increased internal pressure may cause the inflator casing to rupture. Metal fragments could be propelled upward toward the windshield, or downward toward the front passenger?s foot well, possibly causing an injury to vehicle occupants.

What stands out
Of the 9 model years of Honda Ridgeline we track for visibility problems, this one carries the most owner complaints on file — 14.
No new NHTSA visibility complaint has been filed on this vehicle in over 17 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.

The failure pattern owners describe
Owners of 2006 Ridgeelines report spontaneous glass failures across multiple windows. The rear sliding glass panel shatters without any external impact while parked or driving; one owner traced fracture lines to a spring-loaded pressure switch pin in the window mechanism that may be causing repeated stress on the glass. Door windows explode without warning, particularly in hot weather, leaving no evidence of stone damage. A windshield developed a stress crack from the upper passenger corner without visible impact.
Climate control is another major complaint. Blower motors repeatedly overheat and burn wiring insulation—one owner's truck failed at both 35,000 and 72,000 miles. Dealers blame clogged cabin air filters, but independent mechanics suspect faulty transistors or design defects. Repairs run $2,200 or more. AC refrigerant systems fail seasonally: hose leaks one summer, clutch failures the next, with repeated costly repairs yielding no permanent fix.
Safety-critical systems also malfunction. Windshield wipers fail completely in winter storms, disabling visibility when owners need them most. Windows lower themselves while the vehicle sits parked with the engine off. An instrument cluster display freezes or blacks out intermittently.
These failures cross multiple systems and occur regardless of owner maintenance, suggesting systemic design or manufacturing issues rather than individual part defects.
Failure modes owners describe
Rear sliding glass panel spontaneous shattering
Center rear sliding glass panel explodes without impact. Owners report fracture patterns suggesting failure initiated at pressure switch pin mechanism. Glass shards scatter into cab and bed. No external cause found despite thorough investigation.
When: While parked; also while driving through drive-thru display; one owner reported partially open condition during highway driving
Symptoms owners cite: Sudden explosive shattering of rear sliding glass; Fracture lines radiating from pressure switch pin area; Complete glass failure with large pieces falling; No evidence of impact or external object
Repairs/costs cited: Replacement rear glass panel required; one owner identified defective pressure switch pin mechanism as likely cause point
Door window spontaneous shattering
Passenger and driver side door windows shatter without cause while vehicle parked or driving. No impact found. Occurs in various temperature conditions including hot weather (95°F+).
When: While parked at work; while driving on freeway; during high ambient temperature days
Symptoms owners cite: Spontaneous window glass shattering; Glass falls into door cavity; No visible impact or stone damage; Occurs at high temperatures
Repairs/costs cited: Window replacement required
Windshield stress cracking
Windshield develops stress cracks starting from upper passenger corner and propagating toward center. Dealer attributes to stone impact, but owner found no impact divot.
Symptoms owners cite: Stress crack initiating at upper passenger corner; Crack propagating toward windshield center; No visible impact point or stone damage
Repairs/costs cited: Windshield replacement likely required
Blower motor overheating and wiring melt
AC/heat blower motor overheats, causing power cable insulation to melt. Occurs repeatedly on same vehicle at different mileages. Clogged cabin air filter cited by dealer, but independent mechanic suspects faulty transistor or design defect.
When: First failure at 35,000 miles; second failure at 72,000 miles
Symptoms owners cite: Blower motor starts intermittently, then stops completely; Melted or burned wiring visible; Motor burns up; No AC/heat function; Possible fire risk from melted cables
Repairs/costs cited: Blower motor replacement; wiring harness replacement; one estimate $2,200 for full repair; independent mechanic suspects transistor fault rather than filter blockage
Recalls/TSBs owners mention: Honda blower motor harness recall issued (date April 26, 2010 per one complaint), but did not resolve AC cooling issue in that case
AC clutch and refrigerant system failure
Air conditioning loses cold output repeatedly over consecutive summers. First incident dealer attributed to hose leak, second to condenser clutch failure. Problem persists despite repair attempts.
When: Summer 2008 (around 35,000 miles); summer 2009
Symptoms owners cite: No cold air from AC; AC works one summer, fails the next; Condenser clutch malfunction suspected
Repairs/costs cited: First repair (hose replacement) $200+; second diagnosis and proposed repair (clutch replacement) ~$1,000
Windshield wiper complete failure
Windshield wipers fail completely during snow/storm conditions, disabling vehicle safety function. Problem recurs on same vehicle within less than one year despite prior repair attempt.
When: During winter storm/heavy snow conditions; recurring failure within one year
Symptoms owners cite: Total wiper motor/linkage failure during storm; Wipers do not operate; Wipers not frozen to glass; Safety hazard in low-visibility weather
Repairs/costs cited: Repair attempted once but problem recurred within one year
Power window unwanted operation when parked
All four windows lower themselves while vehicle is parked and engine is off. No user input or ignition activity. Dealer found nothing wrong upon inspection.
When: While parked with engine off
Symptoms owners cite: Windows drop down without driver input; Occurs on all four windows; No engine running during failure
Instrument cluster display intermittent malfunction
Mileage display works intermittently, goes out completely, or freezes.
Symptoms owners cite: Display intermittent operation; Complete display outage; Display frozen, not updating

What owners are reporting 2 most recent
While riding down the highway the back window that opens and closes shattered all over two people in the truck. I thought all the glass in the vehicle was suppose to be safety glass. There was no reason behind the glass shattering, it just exploded. Other windows in the vehicle were also down. *tr
While driving the vehicle through a drive through christmas light display area, the rear sliding glass shattered while partially open. No evidence of impact was found inside or outside the vehicle. Fortunately the children were not in the vehicle rear seat at that point in time. Searching the internet, I found a forum that have several other people has had this happen to them as well.*tr

Common questions
How serious is the visibility problem on the 2006 Honda Ridgeline?
It's a meaningful issue. 14 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $350.
At what mileage does the visibility typically fail?
Across the 13 complaints that reported odometer mileage, most visibility failures cluster between 34,900 and 85,820 miles, with the median around 38,000. A quarter of owners report trouble before 34,900; a quarter make it past 85,820. 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 $350 for visibility 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 visibility?
No active recalls currently cover visibility 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.
