Summary

14588b - special coverage (revised to add 2016 my chevrolet impala). On some police patrol vehicles, idling the engine for extended periods of time can prematurely wear the engine-cooling-fan motor. In this condition, the motor may fail to operate or operate noisily. This condition can also damage motor-control relays in the vehicle’s underhood bussed electrical center (ubec). Dealers are to diagnose and replace fan motors per pi1384 regarding the semi-annual preventative maintenance check for police vehicle cooling fans.

Owners of these vehicles have filed 176 complaints in the engine category.
