Subject
The Powertrain Control Module (PCM) on about 59,000 of the above vehicles may have been inadvertently programmed with software that may not run the Downstream Oxygen Sensor Slow Response Monitor as frequently as required by regulations. This can allow an improperly operating Oxygen Sensor to go undetected and result in excessive exhaust emissions which may exceed EPA and California Emissions Standards.
Repair
The Powertrain Control Module (PCM) must be reprogrammed (flashed).

Vehicle Lists, Global Recall System, VIP and Dealer Follow up
All involved vehicles have been entered into the DealerCONNECT Global Recall System (GRS) and Vehicle Information Plus (VIP) for dealer inquiry as needed.
GRS provides involved dealers with an updated VIN list of their incomplete vehicles.
The owner's name, address and phone number are listed if known. Completed vehicles are removed from GRS within several days of repair claim submission.
To use this system, click on the "Service" tab and then click on "Global Recall System." Your dealer's VIN list for each recall displayed can be sorted by: those vehicles that were unsold at recall launch, those with a phone number, city, zip code, or VIN sequence.
Dealers must perform this repair on all unsold vehicles before retail delivery. Dealers should also use the VIN list to follow up with all owners to schedule appointments for this repair.
Recall VIN lists may contain confidential, restricted owner name and address information that was obtained from the Department of Motor Vehicles of various states. Use of this information is permitted for this recall only and is strictly prohibited from all other use.
