October 2012

Dear Chevrolet Customer:

Certain 2013 model year Chevrolet Volt vehicles can be affected by incorrect calendar date information sent through the telematics systems. If a significantly incorrect date is received (for example, 00/00/0000), and the vehicle is in the "delayed rate and departure time" charging mode, the Hybrid Powertrain Control Module (HPCM2) may reset and open the propulsion power relays. As a result, we have received a few reports from owners that their electric motor has temporarily stopped working due to this software anomaly when their vehicle is in the delayed time and rate charge mode.

Your satisfaction with your 2013 model year Chevrolet Volt is very important to us, so we are announcing a program to prevent this condition or, if it has occurred, to fix it.

What We Will Do: Your Chevrolet dealer will reprogram the HPCM2 to make the software robust against incorrect calendar date information. This service will be performed for you at no charge until October 31, 2014. After that, any applicable warranty will apply.

What You Should Do: To limit any possible inconvenience, we recommend that you contact your dealer as soon as possible to schedule an appointment for this repair. Until the reprogramming can be performed, please change your vehicle's charging preference to the Immediate or Delayed Departure mode to prevent this condition from occurring.

If you have any questions that your dealer is unable to answer, please contact your Volt Advisor. The contact information is 877-4-VOLT-INFO (877-486-5846) or Voltfda101@gmexpert.com.

Courtesy Transportation: If your vehicle is within the New Vehicle Limited Warranty, your dealer may provide you with shuttle service or some other form of courtesy transportation while your vehicle is at the dealership for this repair. Please refer to your Owner Manual and your dealer for details on Courtesy Transportation.

We sincerely regret any inconvenience or concern that this situation may cause you. We want you to know that we will do our best, throughout your ownership experience, to ensure that your Chevrolet Volt provides you many miles of enjoyable driving.
