I bought my car 3 days ago and have noticed that every time I start it up for the first time each day I hear what I am assuming is a HVAC vent moving. Does anyone else have this and will the dealership do anything about it?

 

Mine does this depending on what the setting is at startup. And it only happens when I first start the car when it's cold.
From what I can gather from research it seems to be the servo motor or blend door motor. I just haven't taken the time to try and record it and contact the dealer. It should definitely be covered under warranty.

 

This happens to me too, a lot. Every time I start my car in the morning with passengers inside they look at me weird and I have to say, it wasn't me, it was the car... Then they just laugh...

 

Same thing happens in my 2014 IS350 which I had for almost 4 years now. I only started noticing this noise in the morning in the past few months.

 

I had this problem on my 2014 then I started hearing a whining noise, turned out blower motor went

 

My 2014 had the HVAC groan, but it was intermittent, so I didn't report it to the dealer. The 2016 hasn't made the noise so far.

 

I knew I wasn't the only one! I wonder if the dealer will fix it if possible.

 

Also dramatically changing the AC temp will cause it

 

I had this same issue and was told it was a problem with a heaterbox motor. The dealership took care of it. I was able to repeat the problem at the dealership by setting auto temp from low to high, or vice versa.

 

Exactly happened to my previous 2011 IS350 , its lasted for couple month and died out completely in the middle of winter, turned out it was the Blower Fan Motor, Lexus costs 300$ CAD around 220$ USD, replaced it with Aftermarket premium one, no more noise, i found out Lexus Blower motor Fan is defected. You should contact dealership right away and let them know.

 

Oh finally! I thought I was crazy. I have a 2014 IS350 and it's been making a noise for a couple months.

 

Have 2015 IS350 with 39,000 miles and it is doing this also..

Dealer covered it?

 

Ask them and see, my 2011 one was out of warranty when it happened, sometimes when people change their cabin filter they breaks the cliff that holds the fan so it makes noise but if u have never changed or touched anything in there most likely the blower fan motor is on his way to hell.

 

Yep 2011-2014 IS series shared same Fan Motors, Lexus Fan Motors Quality Control guy was slept on his job that's why this happens to some IS350, you're not crazy lol when it 1st happened to me i thought Helicopter flying above my sunroof, my friend heard the sound he said, Yo is that Lexus special instruments ? are we flying Helicopter ? i was like sit back and relax, i turned on Rap musics LOUD problem solved !

 

Is this the source of the stomach growling noises? I hear stomach growling in the mornings. Sometimes sounds like toots and farts.
