I know the owner’s manual describes the evaporative emissions system doing a leak test about 5 hours after turning off the engine. I’m getting a venting type noise, a purr sound, for about 3-5 seconds pretty soon after (maybe within 5 minutes) of turning off the engine. It seems to be coming from around the driver’s side near the rear of fuel tank. Normally I am not near the vehicle after turning it off so I don’t know how often it happens. It is running great, no messages in the display and fuel mileage is normal. Has anyone experienced this? I’m assuming if something was not right, the computer monitoring would communicate it. Thanks.
