Julie J Posted April 27, 2023 Share Posted April 27, 2023 I am getting an intermittent vibration under the hood. Won't replicate when at dealer. The whole radiator "vibrates" when it does it & makes a whirring noise. any ideas? Quote Link to comment Share on other sites More sharing options...
RX400h Posted April 27, 2023 Share Posted April 27, 2023 Does it do this only when an engine bay fan turns on? Quote Link to comment Share on other sites More sharing options...
Bykfixer Posted April 27, 2023 Share Posted April 27, 2023 Sounds like it could a busted fan mount. Turn on the AC, which activates the fans and see if that causes it. Quote Link to comment Share on other sites More sharing options...

Julie J Posted April 28, 2023 Author Share Posted April 28, 2023 Just now, Julie J said: I think so. The problem is it is intermittent. Not all the time. Not every time the fan is on. Quote Link to comment Share on other sites More sharing options...
RX400h Posted April 28, 2023 Share Posted April 28, 2023 In this case, the dealership should keep your vehicle, overnight and run it when it is cold and fully warmed up. This is common procedure when an issue is intermittent. Quote Link to comment Share on other sites More sharing options...
