Mitaine Posted July 18, 2021 Share Posted July 18, 2021 (edited) Anybody noticed the fuel pump or something from the back undercarriage going On if you leave a door open more than 5 or 10 minutes? It happened to me a couple times now and I have to recycle the ignition (without starting the engine) to get the noise to stop. Strange as it could drain the battery or toast the pump. BTW, both my GF and I have the exact same car, even to the color and I couldn't get hers to display the behavior mine does.

LBSypher Posted July 19, 2021 Share Posted July 19, 2021 Are you sure it's not the fuel system check doing its thing? Specifically, I mean the fuel evap test that pressurizes the system to see if a leak in the system is detected. I know it's supposed to happen hours after you turn off the car, but maybe you're somehow getting it to start earlier?

jMeG Posted July 24, 2021 Share Posted July 24, 2021 It just starts humming non stop and I have no check light upon startup. Make a detailed video of exactly what happens and the chain of events. Make sure to take your phone over the fuel pump so everyone can clearly hear the hum. Upload the video to youtube in 4k and post on here. Send the video to your local dealer/service advisor. If they're clueless, send it to SOA. Link to comment Share on other sites More sharing options...

If they're clueless, send it to SOA. I might if it does it again. But for other issues, I've not been impressed by my dealer and SOC. So the less I do business with them, the better.
