A droning type noise may be noted when the air conditioning system is operating. Additionally, a vibration may be felt in the steering wheel. If these issues are no longer present when the AC system is turned off, the problem may be low refrigerant charge in the system.

The vehicle battery is connected to the fuse box via a heavy duty cable. It has been determined that the cable connection at the fuse box can degrade over time, resulting in increased electrical resistance. This increased resistance can cause the connection point to overheat and break, resulting in a loss of electrical power and causing the engine to stall, increasing the risk of a crash. Dealers will replace the positive battery cable connector and secure it with an improved method to correct this concern.
