- 2017 Explorer XLT 4WD
I have a 2017 XLT 4WD v6 with 34k miles. Since I bought it, I've noticed a faint, but audible/noticeable whistle sound when applying light throttle while cruising, and when releasing that light throttle. It sounds like it is coming from the driver side, engine bay. My best guess would be that it is coming from the air intake somewhere, but when I try it while idling I don't hear the sound. Only while driving at cruising speeds and making minor adjustments. Sometimes the whistle is a bit longer/more noticeable on the deceleration after letting go of the throttle, but once the car normalizes speeds again, it instantly disappears. Hard acceleration also does not make the sound.
Any ideas? I just bought it a few weeks ago, did not notice it on the test drive, but with mild talking/music it is easy to miss.
