Issue:
The customer may express a concern that the heat distributed across the surface area
of their heated steering wheel is inconsistent. The areas around the stitching and
spokes, or the lower half of the steering wheel, may appear cooler than the rest of the
wheel.
The heated steering wheel is otherwise operating correctly, and no DTCs are stored.
Cause:
Due to the construction of the steering wheel heater insert, the distribution of the heater
element cannot be uniform across the whole of the steering wheel surface.
The heater element needs to be diverted around the stitched area in order to prevent
breakage of the element during assembly of the steering wheel, while the heater insert
itself needs to be diverted around the steering wheel spokes to allow it to wrap the
steering wheel without bulging or creasing.
Please see the images in the accompanying attachments which illustrate these
characteristics and highlight spots which may appear cooler.
Action:
Vehicles presented with the above issue should NOT have their steering wheels
replaced under warranty.
Instead, please manage the customer’s expectation of how the steering wheel heater
will work, by referring to the information and images supplied in this SSM.
Technicians - Please rate this SSM and provide comments so that future
communications can be improved.
