Larissa Stoffels
DTNA Executive Manager, Vehicle Safety

Portland, OR 97217

 

Dear Cummins Westport OEM Customer:

 

We are writing to inform you that Cummins Westport Inc. has determined that a safety-related defect exists in certain B6.7N engines that were manufactured between February 6, 2018 and September 1, 2020.  Cummins Westport has initiated a recall of the subject engines.  Our records indicate that some of these engines have been shipped to you.

 

A copy of Cummins’ initial Part 573 Equpment Defect Report is enclosed.  This notification was submitted to the National Highway Traffic Safety Administration (NHTSA) on February 17, 2021.  As more fully described in the Defect Report, the engine may not limit engine torque or speed when it receives a J1939 TSC1 message.  If this message is from certain electronic controllers on the vehicle that perform safety-related functions, this may increase the risk of a crash.

 

Enclosed is a list of Engine Serial Numbers for affected engines that our records indicate were shipped to your plants.  For engines installed in vehicles that have left your control, we encourage you to make a safety defect determination in accordance with 49 USC 30118 et seq. and, as appropriate, to submit a Defect Notification to NHTSA in accordance with 49 CFR Part 573.  Cummins will conduct the recall, including notifying owners pursuant to 49 CFR Part 577, performing the remedy, and submitting quarterly status reports to NHTSA. Cummins is requesting that you provide the associated vehicle model identification, VINs and owner contact information to facilitate owner notification.  Please work with your Cummins account team leader to ensure that the requested information is provided to Cummins as soon as possible.

 

For engines/vehicles that are still in your inventory, please contact the Customer Quality

Assurance representative at the Rocky Mount Engine Plant to arrange for repairs, as necessary.  Please note that Federal law prohibits delivery of these engines, or vehicles equipped with these engines, under a sale or lease until this condition has been remedied.

 

Cummins Westport and Cummins will conduct a safety campaign to recalibrate the Engine Control Module with a corrected calibration to remedy the recall condition.

 

Cummins Westport and Cummins apologize for this inconvenience, but we are initiating this action in the interest of our customers’ safety and satisfaction with our products.  Thank you for your assistance.

 

Please confirm receipt of this communication.

 

Sincerely,

 

Steve Collins

OEM Service and Quality Leader
