Lexus RX 2010-15 :: Fluttering Sound From The Heater Vent On Windy Days
Oct 20, 2014
My 2010 450h emits a fluttering sound on windy days. The noise sounds like a hvac flap could be vibrating when the wind hits. The noise is not loud by any means, however can get very annoying hearing it everything the wind gusts hit when you are at a stop. The other afternoon I was doing some basic winter prep under the hood and I could hear it under the hood as well.
I got my 2010 as a Lexus CPO early in 2013 and the noise has been there since day one, it's not something that developed recently. The last time I took it in I got a fail to replicate response from the dealership.

I have a very large rattling/vibrating sound when I am driving highway speeds. This only happens when the temperature is warm, and when a wind gust hits my truck (or if I am passing a Semi). When I drive to work in the morining, there are no issues. When I drive home in the afternoon, it will start within 5-10 minutes of hitting the highway. I have checked for any loose bits and pieces but I cannot find any. I have attached a sound recording of the issue.

So the story goes that one day my 2013 RX350 stop blowing heat from the air vent. I took my car in the dealer to have to take a look. First of all, it took them a WHOLE week to diagnosis the problem, second of all, a consultant told me that he FOUND a pen inside the heater box that caused the gear shaft to break, which is used to control the heater doors...
What is he talking about? More importantly, he's saying I "accidentally dropped a pen" from the passenger side compartment storage and it somehow caused the heater door broke?

So, lately I've noticed a slight fluttering sound in my '08 GS460 when accelerating on the freeway or up a slight incline. It'll kick in around 2,000-4,000 RPM, and it almost sounds like it's coming from right underneath the center console. I did have an exhaust system installed, then uninstalled, so maybe it's something the shop did, but can't be positive whether or not it was there before (always drive with my music on pretty loud).

I have a 2004 GX470. Now that the weather has dropped I have noticed that my heater is taking a long time to warm up all it does is blow cold air out of the vent. Subsequently I have started to notice that they car will start to overheat. It will never get to the point where it will hit the red but it will go up and then come back down to mid range. There doesn't seem to be anything else wrong with the car, it idles fine, starts fine etc. Could these two issues be related?

Today I noticed a sound as I was driving almost like I forgot to shut a door. I believe it is coming from the vent which is located on the right side of the back seat. I'm not sure if I ever heard this before. It's been in the 90's this week.

When I turn the fan on, the sound I get from the vent is *tick* *tick* *tick* *tick* as the fan turns. Does the whole dashboard has to come out fix it? I am hesitant to bring it to the dealer & have him rip the whole thing apart just for the fan ticking, but it sure is annoying too. It started about 6 months ago here.

My Mom purchased a new 2011 Lexus RX350 last spring. The dealer installed a remote starter at the time of purchase (we live in Alaska). We've had a continuing problem with the battery going dead if the car has not been driven for a period of time (like 4 days). When she does drive it, it is for short trips (3 miles round trip to work). The original battery was replaced in fall with a heavy duty one, but the problem continues. Its been to the Lexus dealer (130 miles away) several times, but they claim everything is within the tolerances and "there is no problem".
They did note that the remote starter was drawing more than it was suppose to and reinstalled it. Their finding was that she was not driving it enough and recommended a battery tender, which has been installed. That works as long as she plugs it in daily. However, if a plug in is not available (like at the airport, hospital or if she is visiting) the battery goes dead after 4 days (even after it has been driven 100 miles).

i have noticed ever since i got my 15 rx that on hot days when i get in, and start it up. there is a pretty long delay before the a/c starts blowing? kinda stinks when its hot out and the inside of the car is even hotter? all i know for sure is my 01, and 05`s used to come on almost instantly, so just curious if this is just the way its supposed to be on the 15.

I'm trying to remove the middle console vent cover to install a kuda mount. It says to pry a bit with plastic tools right to the right of the vent between the plastic and the leather/pleather. Getting nervous and don't want to crack the cover or damage anything.

I've got a 99 1.8t, and every once in awhile when the turbo starts spooling I hear a fluttering, not sure how to describe it. sort of like when your valves run low on oil and you can hear em tick? Like something is fluttering in the turbo when its spooling, instead of just a steady sucking of air.

When I start the car in the morning & step on the gas there is a fluttering noise which happens each time I accelerate until it warms up. I bought the car with 17,000 miles on it and I didn't notice it happening then, but it was warm weather then.

So last couple days over the 4th, the heat was over 95.
AC Blowing out of the vent is cold but the rear seats passenger feels warm.
Even with the blower on the higher and temp on the lowest 65 (or lowest setting).
I put my hand towards the rear seat and I feel warm air. Near the vents are cool but its like the AC can't keep up with the heat ?

Ok here is my question. I've noticed the power on my car has felt inconsistant for the last little while. I finally got around to logging the car and my boost peaks at mid 20's just over 3000 RPM and then drops fast to between 13-15 psi before I even get to 5000 RPM.
Under full boost I hear a low fluttering sound like the diverter valve opening and closing when this is happening. I also don't get the typical diverter valve sound when shifting when the car is doing this.
I took my diverter valve out and inspected it. I can pushing the piston up very easily with almost no resistance, is that normal? I would think that it should be hard to push the piston up if not wouldn't boost pressure be able to overcome the piston and leak past?
My mods are. HPA tune, HPA catted down pipe, and VWR intake.

When I started the V^ Passat today it made a fluttering/imitation purring kind of sound...not re-assuring at all. What it could indicate? It only lasted a second then fadded out and ran fine.
maybe a belt tensioner or oil pressure regulator or something like that getting up to snuf?

The heater fan quits working on colder days. It is not the fan motor, as twice after it has quit, several days later the fan began working again. As controls are switched, the indicators light and mode shifting sounds can be heard. It seems to be that the fan quits on the colder days (<38 deg) the will resume working again when the outside temperature exceeds 50 degrees.

I noticed that driving my LS last weekend that the right headlight was fluttering going down the road. It did not go off but it looked like a loose connection. When I arrived at the golf course, someone told me that he noticed that the right headlight was out. Now I got home and I have checked the headlight and nothing seams to be a problem. Both low beam and high beams go off and on with no problem. My question is : is the headlight bulb going out or do I have a connection problem? I hate to take off the tire and inner wheel cover to change the bulb unless I need to. Second question: If I have to change the bulb what is the best brand to use?

I bought a white 2015 Sonata GLS with 55000 kms on it. Car works fine but really great on gas in city with AC ( 11-12 liters/100 kms ).
And my main problem is my AC/heater vents. Its nice cool day out and I wanna roll my windows up and use outdoor air (with AC off and heating knob on cool - Blue side) but still blow warmer air (the more I turn the temp knob to less cool side more warm air comes out). I went to dealership and complaint about it but they said can't duplicate problem. And I replaced cabin air filter too, but still same problem.
I don't have automatic temperature climate control option, so its all manual, red and blue setting for heat and cold. I complaint them may be my heater stuck on heating but no action taken from them..

The audio system sound in my 2005 GX470 suddenly quit working properly.
When first starting the car, I have no sound from any of the system sources (am/fm radio; tape; cd player). After the heater warms up the car, usually about 5-6 minutes, the sound comes on and all sources work fine.

I just bought a 2010 F150 XLT XTR SuperCab 4X4 with a 4.6L 3V engine. I had a 2003 5.4L and a 2004 V10 before and this new engine seems to be nosier then the older ones I've had. It's a ticking/fluttering type noise I here when I'm standing outside the truck while it is idling. Is it normal for these newer 3V engines to make this noise? My wife has a 2009 Hyundai Santefe and it makes a similar noise just not as loud. Does the 5.4L make a similar noise also?
