What stands out

No new NHTSA visibility complaint has been filed on this vehicle in over 10 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
Ten complaints cluster around visibility-related issues on the 2009 H3, predominantly centered on HVAC system failures linked to NHTSA Campaign 15V421000. Owners reported blower motor failure at 136,000 miles and connector module failure (controlling blower speed) at 100,000 miles, both accompanied by burning odors under the dashboard. One ventilation system emitted an abnormal odor when engaged, rendering it inoperable. A defroster system failed to produce cold air at 33,500 miles; when an owner sought dealer repair under the recall, the dealer refused, claiming the issue had been previously remedied.
The common thread across multiple complaints was unavailability of replacement parts. Owners stated the manufacturer could not provide estimated delivery dates for recall repairs, effectively leaving vehicles unrepaired for extended periods despite recall notification.
A separate critical issue emerged: one windshield was not properly glued at the factory, allowing water intrusion during rain. Water entered the vehicle's computer system, preventing the engine from starting for 20 minutes and causing dashboard lights to malfunction. A sun roof drain tube repair attempt did not resolve the water leakage, and the manufacturer stated no recall applied.
