| 511640 | 2023-07-05. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM; ELECTRICAL SYSTEM. According to General Motors Recall 23V247: "These vehicles are equipped with an unused circuit that a final-stage manufacturer may elect to use to install an optional rear HVAC system. If the final-stage manufacturer leaves the circuit's connectors or cut wires unsealed, exposure to moisture or contamination may, over time, cause corrosion. This could result in high current draw through the circuit at the vehicles' lower left side B-pillar. Unintended release of excessive heat from the circuit may pose a risk of a vehicle fire and increase the risk of injury." |
