Plastic noise near driver left knee

welcome! does it happen at any particular time, acceleration, speed, bumps, turns, braking, etc.?

 

so,it's all the time, or intermittently?

 

is that the door panel, or in front of it?

 

there were a lot of complaints about dash squeaking noises on the early gen 3's. it's usually where to surfaces meet, like the left end and the side panel. i would let the dealer sort it out under warranty. it probably invokes removing the dash and adding material between the mating surfaces.

 

Welcome, dan. There's been a couple threads about squeaks/rattles in the dash area; or under the dash; or in the door panel. I believe the guys had a simple fix with some sticky foam tape?

 

White heater vent

 

I heard two odd unusual sounds in my Prius this morning. I want to wait and see if I hear it again, before I comment further.

 

Had my 2016 Prius for 10 days now. Heard similar intermittent plastic noise as well but at different spot. Mine was at passenger side. I think it was one of the plastic panels on the door. I pressed down firmly on each of the parts on the passenger doors, which seems to be doing the trick. Haven't heard it for a couple days.

Now I just need to figure out the inconsistent vibration on the brake pedal when car is stop with my foot on the brake. It is always when battery is around 2 to 3 bars. I didn't expect to feel that strong vibration when the engine is charging the battery, certainly not with inconsistency.It might be the white heater vent that has been mentioned in the forum. Going to my one month free inspection in a few weeks to get it checked out.

 

Wei, I felt some vibration for the first time tonight. I was stuck in a long drive-thru line getting coffee. My lights were on, and the radio, and the AC. The battery went down to 3 bars. The engine kicked on, rather loudly, and I did feel some vibration but it wasn't very strong. I think it's normal? (And the battery went right back up to full when I started driving.)

 

I think we're experiencing some of the tradeoffs of buying some of the first gen 4s. First model year cars are always the worst put together ones. At least nothing's broken. I've had an annoying rattling sound in the right rear passenger side c-pillar. I'm going to get it fixed when I get an oil change.

 

I've been pretty lucky. I think the "unusual" sounds that I have heard, were just the normal hybrid/electrical/pump sounds. I don't have any annoying rattling sounds anywhere in the dash or doors. No water spots in the headlights. Windows seem to fit tight. Body integrity seems solid. It's great when I come upon one of the few smooth roads, my Prius gets very quiet! It's wonderful.

When the engine kicked on last night (and races and vibrates) to recharge the hybrid battery, it kind of startled me because I was sitting still at the time. But it only lasted a few seconds. It was another good "learning moment", and now I will know what to expect in the future.

 

Are you sure it's not just your knee making the noise?

Mine make strange noises more than they used to.

 

I have the same sound, check this plate and hold it when the sound appear. This plate vibrate with an other piece.

 

I was just on the Toyota Owners website and found this comment to a question about a rattle....might be worth trying.

 

And what's their fix?
