IMPORTANT SAFETY RECALL
April 2021
This notice applies to your vehicle, VIN: _____________________________________

Dear General MotorseBay logo Customer:
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.
General MotorseBay logo has decided that a defect, which relates to motor vehicle safety exists in certain 2021 model year
ChevroleteBay logo Express and GMCeBay logo Savanna vehicles equipped with 6.6L gas engines. As a result, GM is conducting a safety
recall. We apologize for this inconvenience. However, we are concerned about your safety and continued satisfaction
with our products.

IMPORTANT



Your vehicle is involved in GM safety recall N202325161.
Schedule an appointment with your GM dealer.
This service will be performed for you at no charge.
Your vehicle was repaired previously for this condition under a
Technical Service bulletin. It is included in this safety recall to
ensure the positive battery cable anti-rotation trim length was
trimmed properly when the procedure in the bulletin was
performed.

Why is your vehicle
being recalled?

In certain circumstances, anti-rotation tabs on the positive battery cable terminals may
come into contact with a fuse block assembly attachment post, causing a short circuit.
Clearance between the positive battery cable anti-rotation tab and the fuse attachment
posts is small enough to allow contact in certain situations. Drivers may get a low
battery voltage warning or experience a dead battery. A short-circuit of a positive
battery cable to a fuse attachment post can cause battery drain or may lead to an
underhood fire.

What will we do?

Your GM dealer will inspect your vehicle and remove a portion of the anti-rotation tab
on both positive battery cable terminals near the engine compartment fuse block
assembly attachments. A very small percentage of vehicles may have had too much
of the tab removed during prior servicing. If this is the case for your vehicle, the
battery cable will be replaced. This service will be performed for you at no charge.
Because of service scheduling requirements, it is likely that your dealer will need your
vehicle longer than the actual service correction time of approximately 50 minutes.

What should you
do?

You should contact your GM dealer to arrange a service appointment as soon as
possible.
It is recommended that the vehicle be parked outside and not in a garage or other
structure until it is repaired.

Do you have
questions?

If you have questions or concerns that your dealer is unable to resolve, please contact
the appropriate Customer Assistance Center at the number listed below.
