SYMPTOM DESCRIPTION
About 199,143 of the above Plug In Hybrid Electric Vehicles (PHEV)s may have been built with incorrectly programmed hybrid control processor (HCP) software which may result in a disabled windshield defrost system under certain conditions. Suspect vehicles may not have a functional defrosting and defogging system under certain conditions. A disabled windshield defrost system may decrease outward visibility in certain driving conditions which may cause a crash without prior warning.
The condition above fails to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 571.103 S4.1 requires that “Each vehicle shall have a windshield defrosting and defogging system.”
SCOPE
This recall applies only to the above Plug-In Hybrid Electric Vehicles (PHEVs).
NOTE: Some vehicles above may have been identified as not involved in this recall and therefore have been excluded from this recall.
IMPORTANT:
- Some of the involved vehicles may be in dealer new vehicle inventory. Federal law requires you to complete this recall service on these vehicles before retail delivery. Violation of this requirement by a dealer could result in a civil penalty of up to $27,168 per vehicle.
- Some of the involved vehicles may be in dealer used vehicle inventory. Dealers should complete this recall service on these vehicles before retail delivery.
- Dealers should also perform this recall on vehicles in for service.
Involved vehicles can be determined by using the VIP inquiry process.
REPAIR TO BE PERFORMED
Update the Auxiliary Hybrid Control Processor (AHCP) then update the Hybrid Control Processor (HCP) with the latest available software to enable the defrost electric heater, valve, and pump.
IMPORTANT: The AHCP must be updated first before updating the HCP. Flash order sequence is CRITICAL!
Also update the Battery Pack Control Module (BPCM), Integrated Dual Charging Module (IDCM), Powertrain Control Module (PCM) and Transmission Control Module (TCM) if updated software exists for any of those modules.
ALTERNATE TRANSPORTATION
Dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle if the vehicle must be held overnight.
PARTS INFORMATION
No parts are required to perform this service procedure.
PARTS RETURN
No parts return required for this campaign.

SYMPTOM DESCRIPTION
About 199,143 of the above Plug In Hybrid Electric Vehicles (PHEV)s may have been built with incorrectly programmed hybrid control processor (HCP) software which may result in a disabled windshield defrost system under certain conditions. Suspect vehicles may not have a functional defrosting and defogging system under certain conditions. A disabled windshield defrost system may decrease outward visibility in certain driving conditions which may cause a crash without prior warning.
The condition above fails to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 571.103 S4.1 requires that “Each vehicle shall have a windshield defrosting and defogging system.”
SCOPE
This recall applies only to the above Plug-In Hybrid Electric Vehicles (PHEVs).
NOTE: Some vehicles above may have been identified as not involved in this recall and therefore have been excluded from this recall.
IMPORTANT:
• Some of the involved vehicles may be in dealer new vehicle inventory. Federal law requires you to complete this recall service on these vehicles before retail delivery. Violation of this requirement by a dealer could result in a civil penalty of up to $27,168 per vehicle.
• Some of the involved vehicles may be in dealer used vehicle inventory. Dealers should complete this recall service on these vehicles before retail delivery.
• Dealers should also perform this recall on vehicles in for service.
Involved vehicles can be determined by using the VIP inquiry process.
REPAIR TO BE PERFORMED
Update the Auxiliary Hybrid Control Processor (AHCP) then update the Hybrid Control Processor (HCP) with the latest available software to enable the defrost electric heater, valve, and pump.
IMPORTANT: The AHCP must be updated first before updating the HCP. Flash order sequence is CRITICAL!
Also update the Battery Pack Control Module (BPCM), Integrated Dual Charging Module (IDCM), Powertrain Control Module (PCM) and Transmission Control Module (TCM) if updated software exists for any of those modules.
ALTERNATE TRANSPORTATION
Dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle if the vehicle must be held overnight.
COMPLETION REPORTING / REIMBURSEMENT
Claims for vehicles that have been serviced must be submitted on the DealerCONNECT Claim Entry Screen located on the Service tab. Claims paid will be used by FCA to record recall service completions and provide dealer payments.
