2012 Prius With Passenger Area Slight Rattle

passenger seat belt against the pillar?

 

there are a ton of threads here on different rattles. tough to guess at. try holding the glove door and other areas to see if it stops. a lot has been solved by adding felt between plastic surfaces.

 

There's even a thread about the bracket holding the air intake hose at the front passenger side of the engine bay rattling in the mounting hole and transmitting the sound through the fender into the passenger compartment.

 

I've got the same rattle I believe on my 2011. I drove a 2010 Prius that was in the shop for the same rattle, theirs a lot worse than mine, it was diagnosed as the glove box strut (right side holding the glove box open). I've been since playing around with it on my own vehicle...cannot tell if that is exactly it or not. I wasn't able to drive the other Prius after the repair. That's what a tech told me. Mine only happens when cruising on EV power, then slightly pushing the gas pedal, the ICE turns on, the rattle will appear, 20-35mph. Only when pedal is pressed slightly. Rattles are the worst.

 

Awesome!! Glad that was it. Gonna try stabilizing mine tomorrow.

 

This sounds a lot like the problem I'm having! A week ago I opened the glove box for the first time in a long time and the problem started soon after. Did not put that together until now! Gonna look into it in the morning.

 

I have a rattle that sounds as if it comes from the glove box lid. Actually, it apparently comes from the loose attachment of the bottom rear of the flying buttress near the front of the center console box.
