On some 2011-2015 model year Chevrolet Caprice and 2012-2015 model year Chevrolet Impala 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).
