Fuel Heater May Overheat and Cause Fire – Cummins B6.7 Medium Duty Diesel Engines

March 4, 2019 NHTSA CAMPAIGN NUMBER: 19E020000

Fuel Heater May Overheat and Cause Fire

A fire increases the risk of injury. An engine stall can increase the risk of a crash.

 

NHTSA Campaign Number: 19E020

Manufacturer Cummins Inc.

Components FUEL SYSTEM, DIESEL

Potential Number of Units Affected 46,194

 

Summary

Cummins Inc. (Cummins) is recalling certain B6.7 medium duty diesel engines, part number D313029BX03, used in school buses, trucks and emergency vehicles, equipped with fuel module option number FS90301 or FS90453. The electric fuel heater within the fuel module may overheat and cause plastic in the fuel heater to melt and potentially catch fire. It may also lead to engine stalling.

 

Remedy

Cummins will notify the owners that have the affected engines in their vehicles. Cummins is still developing a final remedy. In the interim, owners will be mailed a letter advising them to remove the fuse supplying electrical power to the subject fuel heater and to inspect the heater for fuel leakage or damage and, if found, to contact Cummins to arrange for a repair (remove the damaged or leaking heater and replace it with a plug). Cummins issued owners an interim notification on May 2, 2019. The recall began August 9, 2019. Owners may contact Cummins customer service at 1-800-286-6467.

 

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Engine Serial Number	Vehicle Model	Vehicle Identification Number
74094787	4300 4X2	3HAMMM

  *** IMPORTANT SAFETY RECALL*** NHTSA Recall No. 19E020 Interim Recall Notice   May 2, 2019   Dear Cummins Customer: This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. Cummins Inc. has decided that a defect which relates to motor vehicle safety exists in certain B6.7 diesel engines that were manufactured between December 16, 2015 and February 25, 2019 and equipped with fuel module option FS90301 or FS90453. This notice applies to your engine(s) listed on the enclosed Engine/Vehicle list. Fuel module options FS90301 and FS90453 contain an electric fuel heater.  Internal electrical arcing within the fuel heater may create sufficient heat inside the fuel heater to cause plastic in the fuel heater to melt and potentially catch fire.  It may also cause an engine stall.  A fire, if undetected and uncontained, presents an increased risk of personal injury.  An unexpected engine stall may increase the risk of a crash.  If this condition exists, melting of the fuel heater may be visible during a service event, smoke may precede or accompany a fire or the engine may become increasingly difficult to start. Cummins is currently developing a permanent remedy for this issue.  You will receive a second notification to inform you when the final remedy is available and to provide instructions to schedule the recall for your engine. In the meantime, Cummins advises you to take the following actions to mitigate the safety risk:

• Locate the fuel filter module and fuel heater at the driver’s side front of the engine as shown in Figure 1 below.
• Inspect the heater and module for any signs of damage or fuel leakage.
• If there is no damage or leakage after engine shutdown, remove the fuel heater fuse as shown in Figures 2 or 3 below (based on application) and leave the wiring harness connected.

*** IMPORTANT SAFETY RECALL***
NHTSA Recall No. 19E020
Cummins Campaign #C2127

 

August 9, 2019

Dear Cummins Customer:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

Cummins Inc. has decided that a defect which relates to motor vehicle safety exists in certain B6.7 diesel engines that were manufactured between December 16, 2015 and February 25, 2019 and equipped with fuel module option FS90301 or FS90453.

Cummins previously mailed you an interim notice advising you of this recall and informing you that you would receive this second notice when the remedy is available.

This notice applies to your engine(s) listed on the enclosed Engine/Vehicle list.

 

WHY IS A RECALL BEING CONDUCTED?

Fuel module options FS90301 and FS90453 contain an electric fuel heater.  Internal electrical arcing within the fuel heater may create sufficient heat inside the fuel heater to cause plastic in the fuel heater to melt and potentially catch fire.  It may also cause an engine stall.  A fire, if undetected and uncontained, presents an increased risk of personal injury.  An unexpected engine stall may increase the risk of a crash.  If this condition exists, melting of the fuel heater may be visible during a service event, smoke may precede or accompany a fire or the engine may become increasingly difficult to start.

 

WHAT ARE WE DOING ABOUT THE PROBLEM?

Cummins has released field Safety Campaign #C2127 “B6.7 MY2017 Fuel Heater Safety Campaign” to correct this condition.  The remedy will consist of the following: (1) change the fuse in the vehicle to a 30A fuse, including installing revised fuse size information in the vehicle owner’s manual and, in school bus applications, the vehicle fuse map, (2) reverse the polarity of the wiring to the fuel heater, (3) install a new fuel heater and (4) put a white paint dot on the fuel heater connector on the OEM wire harness (to readily identify units which have had the recall completed).  Repair parts are currently available at Cummins Distributors and authorized Warranty Dealers.  The repair will be completed free of charge (parts and labor) and most applications will require approximately 1 hour to complete.

 

WHAT SHOULD YOU DO?

Contact the nearest Cummins Distributor or authorized Warranty Dealer to arrange to have this campaign performed on your engine.  The distributor or dealer will work with you to schedule the best date to complete this repair.

In the meantime, as described in the interim notice, Cummins advises you to mitigate the safety risk by disabling the fuel heater by removing the fuse.  For further information, contact your local Cummins service location at the number below (Reference TSB190038).

Federal law requires vehicle lessors receiving this recall notice to forward a copy of this notice to the lessee within ten (10) days.  Also, it is a violation of Federal law for a dealer to deliver a new vehicle or equipment covered by this recall notice under a sale or lease until the defect has been remedied.

If you previously paid to have this recall performed on your vehicle, you may be eligible for reimbursement.  Please contact Cummins Care at the number below for more information.

 

WHO SHOULD YOU CONTACT IF YOU HAVE FURTHER QUESTIONS OR CONCERNS?

If you have questions or concerns about this recall, please contact your local Cummins Distributor or authorized warranty dealer.  You may also contact Cummins Care at 1-800CUMMINS (1-800-286-6467), or visit our website at care.cummins.com.

If you have a complaint relative to this recall, you may report it to the following:

Administrator
National Highway Traffic Safety Administration
1200 New Jersey Avenue, SE
Washington, DC 20590

 

You may also call the toll-free Vehicle Safety Hotline at 1-888-327-4236 (TTY: 1-800-424-9153); or go to https://www.safercar.gov.
