No US recalls found for the 2010 Hummer H3T.
On certain vehicles, the connector module that controls the blower motor speed in the heat/vent/air conditioning (HVAC) system could overheat under extended periods at high or medium-high blower speed. If this were to occur, it could result in the plastic around the connector module melting by the heat generated, increasing the risk of fire resulting in injury and/or damage to property. Correction: Dealers will replace the female connector and harness.
On certain vehicles, the integral clip-tabs on the hood louver may fracture, which could allow the hood louver to lose its retention mechanism. As the clip-tabs break, the hood louver may rattle against the hood and become loose. If this indicator is unnoticed, additional clips could fracture and the hood louver could detach from the vehicle and strike a vehicle or a bystander, which could result in property damage, personal injury or death. Correction: Dealers will apply an adhesive to the hood louver to secure it to the hood.
