The Positive Battery Cable Connection in the Trunk Can Overheat

The insulated connector for the positive battery cable may have been incorrectly attached to the trunk floor panel, which can lead to a loosening of the bolt connection. Loosening of the connection can cause an increase in electrical resistance and overheating of the cable connection, which could lead to a fire, even when the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been completed. Dealers will secure the battery bolt cable connection as necessary to correct this concern.

 

Brake Vacuum Pump Leaks Oil

The brake system vacuum pump check valve can leak oil and contaminate the power brake booster. This can result in loss of power brake assist. Dealers will repair the vehicle as necessary free of charge to resolve concerns.

Incorrectly Manufactured Transmission Component May Allow Vehicle to Move While in Park

Certain passenger vehicles may have been built with incorrectly manufactured transmission guide plate part.

The dealer will repair and replace the automatic transmission guide plate free of charge. The campaign # is 05V504000
