A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Complaint Noises when reversing slowly \< 4 mph \(squeaking\) Cause There is a seal in the electric drivetrain that seals off the coolant system from the electric motor. This seal is moistened with coolant during forward travel. As a result of the change in rotational direction when reversing slowly, it may be the case that this sealing ring is no longer moistened. Squeaking noises may occur as a result of the so\-called "stick\-slip effect". This behavior does not impact the function or durability of the sealing ring and electric drivetrain. Remedy Do not replace any parts. Explain the cause of the noises to the customer.
