通用汽车已确定某些 2003-2023 年雪佛兰 Express Cutaway 和 GMC Savana Cutaway 不完整车辆中存在与机动车辆安全相关的缺陷。这些车辆配备了一个未使用的电路，最终阶段的制造商可以选择使用该电路来安装可选的后部HVAC系统。如果最终阶段的制造商将电路的连接器或切断的电线未密封，随着时间的推移，暴露于潮湿或污染可能会导致腐蚀。在极少数情况下，这可能会导致高电流通过车辆左下方B柱的电路。电路中意外释放过多的热量可能会造成车辆起火的风险并增加受伤的风险。

General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2003-2023 Chevrolet Express Cutaway and GMC Savana Cutaway incomplete vehicles. 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. In rare cases, 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.
