77tcb Posted February 7, 2017 Share Posted February 7, 2017 Recently purchased a used 2014 RX 350 F Sport, when I walk into the garage I sometimes hear what sounds like an electric motor running somewhere in the vehicle. Any thoughts? Quote Link to comment Share on other sites More sharing options...
TrevC Posted February 8, 2017 Share Posted February 8, 2017 How long after parking it in the garage do you hear the noise? Quote Link to comment Share on other sites More sharing options...

1990LS400 Posted February 9, 2017 Share Posted February 9, 2017 It's a "feature" of all/most vehicles made by Toyota. The following text is from the Toyota Venza owners manual: " Approximately five hours after the engine is turned off, you may hear sound coming from under the vehicle for several minutes. This is the sound of a fuel evaporation leakage check and, it does not indicate a malfunction. " The first time I heard it on one of our Toyotas, I opened a garage door thinking the buzzing was coming from outside. Nope, it was just the emission system doing a self check. 2 Quote Link to comment Share on other sites More sharing options...
