No I kid you not. Only when hot out and at random “booooooop”. Driver side rear quarter. Maybe related to rear ac. Hard to test with ac off ( real hot this week ) but will do. Wife calls it the clown car.2014 XC90 Purchased last year with 47k miles. Dealer thinks I’m nuts. Thanks for any reply or location of flute

Does it have the optional air suspension?

Evita the S70 whistles Dixie when we shut her off on a hot day with AC on.

I suspect it’s AC re-equilibrating

No air suspension. Got panels off to pinpoint. Since most frequent on hot days it must be rear condenser. If so then what. Checked refrigerant. Dead in the middle on gauge. Maybe let some out and add oil ? Why only my xc90. Will be hot tomorrow gonna look again

Leave that AC charge alone. It’s normalfor AC to make someone noise. I don’t know the XC90 system but you don’t get overcharged unless someone puts too much R134 in

Spontaneous generation of refrigerant is a rare event accompanying poultruous dentitis.
