Summary
This Preliminary Information communication provides information to the technician about vehicles that may have a high-pitched whine noise during braking or accelerating. Technician will need to inspect the load floor, in the rear of the vehicle, for being properly secured. If the load floor is not fully seated check the cargo tray under the floor and insure everything is stowed in its own spot. An improperly stowed 120v charge cord set, cargo in the lower tray that can pop the load floor up, and damage to the load floor that causes the floor not to clip into place.

SEOCONTENT-STARTBulletin No.: PIC5412C Date: Apr-2015 Subject: High-Pitched / Whine Noise Heard Intermittently from Behind Rear Seats Models: 2011-2015 Chevrolet Volt This PI was superseded to update Model Years. Please discard PIC5412B. The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. Condition/Concern Some customers may comment on hearing a high-pitched whine noise during braking or accelerating, mostly in Extended Range Mode with the engine running. The noise is coming from the 14-Volt Power Module under the rear load floor. Recommendation/Instructions If a customer is experiencing a high-pitched whine noise from the rear of the vehicle, check the load floor, in the rear of the vehicle, for being properly secured. Check for any noticeable gaps between the load floor and the vehicle. See Photos below The picture below shows a load floor that is NOT properly snapped into place The picture below shows the load floor installed correctly 1 Some of the causes for the load floor not properly secured into place is: 1. A improperly stowed 120v charge cord set 2. Cargo in the lower tray that can pop the load floor up 3. Damage to the load floor that causes the floor not to clip into place. The picture below shows the 120v charge cord set stored properly in its place The picture below shows the 120v charge cord set NOT stored properly, which would cause the load floor not to secure properly in the front and causes a gap and a entry point for noise into the front of the vehicle.
