Diesel Engine Block Heater Cord

 

These questions and answers are being provided to help GM dealers respond to inquiries from involved vehicle owners about the Safety recall identified above. 

Q1) Which vehicles are involved?
A1) 2017-2019 Chevrolet Silverado 2500/3500, 2017-2019 GMC Sierra 2500/3500 and 2019 Chevrolet Silverado 4500/5500/6500 vehicles equipped with the Duramax diesel 6.6 liter engine (RPO L5P or L5D) and the optional engine-block heater cord (RPO K05).

 

Q2) What is the issue or condition?
A2) A short-circuit condition may develop in the engine-block heater cable or in the terminals that connect the heater cable to the block heater.  While GM’s root-cause analysis is ongoing, GM has determined that a short-circuit condition can occur in these vehicles if: (i) a block-heater coolant leak develops and coolant contacts the block-heater cable terminals while the cable is plugged into an energy source; or (ii) the heater cable itself is chafed or damaged due to improper routing, use, or storage.

 

Q3) What symptoms may be experienced?  What warning signs may be associated with the issue or condition described?
A3) If the engine-block heater is on, and this condition is present in the vehicle, customer may notice: (i) smoke or a burning smell; (ii) poor block-heater performance; (iii) tripped circuit breakers or blown vehicle fuses; (iv) damage to the block heater, the heater cable, or engine components; and (v) block-heater coolant pooling under the vehicle.

 

Q4) What is the remedy/repair?
A4) GM will provide this information when available.

 

Q5) What is the safety risk?  Is the vehicle safe to drive?
A5) GM is developing a final repair that will restore the functionality of the engine-block heater.  Until this repair is available, customers should not use the engine-block heater.   Using the block heater could cause a short circuit, which could cause damage to engine components and, in rare cases, start a fire in the engine compartment.

 

Q6) Does the customer have to pay for this remedy/repair?
A6) No, when the remedy is available this inspection/repair will be done at no cost to the customer.

 

Q7) Is the remedy/repair available now?
A7) No, GM is developing a final repair that will restore the functionality of the engine-block heater.  Customers will be notified when this repair is available.

 

Q8) What should customers do until recall repairs can be completed?  Are there any special instructions?
A8) GM is developing a final repair that will restore the functionality of the engine-block heater.  Until this repair is available, customers should not use the engine-block heater.

 

Q9) How can customers check to see if their vehicle is involved in this field action?
A9) Customers who own a vehicle involved in the field action will be notified by mail by General Motors, but they may also check their Vehicle Identification Number (VIN) for field actions in GM Owner Center at https://my.gm.com/recalls or via NHTSA’s website at https://vinrcl.safercar.gov/vin/.

 

Q10) If customers are concerned, can they get a rental car or courtesy transportation?
A10) Courtesy transportation is available for customers whose vehicles are involved in this recall and are within the warranty coverage period for the warranty which is associated with this recall.  Please refer to Warranty Administration Bulletin #17-NA-073:  Field Action Courtesy Transportation Policy for further information.   Medium Duty is excluded from courtesy transportation.
