Prius (Gen 3) :: Loud Noise From Back Seat Vent / Cooling Fan
Apr 6, 2015
Fan is pretty clean. Before re-assembly it will be blasted with ~100 psi from an air compressor. Driving around like this is fine for a while to check diagnostics. How noisy is normal? This is the first time I noticed the noise.
We've owned this silver 2011 Gen 3 from new and it now has 37K miles after about 3.5 years. Today it's ~70F in Atlanta, so not hot compared to how it will be soon. We had the s/w recall done about six months ago and I've possibly not driven the car since (have a few cars).. my wife drives it most days and did not notice probably due to music but I felt it was very loud like there was hole in the side of the car (first thought was some vent to the outside became stuck open but the vent near the auxiliary battery is fine).
Is there a way to read the fan speed via Android Torque and Bluetooth OBD? Should I disassemble the entire length of the venting? Might there be something inside there causing a blockage?

A few weeks ago I started to notice that the battery vent fan was turning on way more than usual. I've had the car now for five years (34K miles) and I've only heard the fan go on a handful of times, even in the hot Las Vegas summers. Once I really started to pay attention to it I noticed the noise only started once I hit about 30-35 mph and got louder as I went faster. As I slowed down, the noise would get quieter and eventually stop as the car came to a stop.
This week I caved and brought the car in to the dealer to get checked out and they did an inspection of the vent, fan and did a complete diagnostic on the hybrid system and batteries. I was worried about damage to the traction battery if the vent fan was malfunctioning or clogged. I'm out of warranty with no extended coverage so I was pretty shocked that the dealer didn't charge me a dime to do the tests. All the tests came back clean and they said all the systems tested above average and that the fan was operating normally so I shouldn't worry about it.
But the noise still persists and it's starting to drive me a little batty. It has never made this much noise before. Is there something else that could be going on that the dealer missed? Maybe the noise I'm hearing is something else and it only sounds like it's coming from that area?

Leak in the passenger door that blows cold air on the unsuspecting front seat passenger that is intended for the back seat door frame vents? I say 'the' leak because we checked other Tregs at the dealer with similar gaps between the door and gasket on the passenger side.

How the rear seat vent works? When you started your car and car was moving, did you notice that vent is always blowing? OK, I just notice that my rear seat vent just keeps blowing when my car is moving. Especially, it is loud as I hear when I turn off my radio.

I sat in the back of my recently purchased 2011 Prius Three, not III, for the first time yesterday. I learned from this forum that the vent in the rear seat is to keep the hybrid battery cooled. However, while sitting the back during a ride, I noticed it was blowing air out instead of sucking air. I would think the vent should be sucking air from the cabin to keep it cool, but that does not seem to be the case here. After a 30 minute drive, I even felt the air coming out of it was warm and the A/C began to feel that it was not enough for my area in the back of the car.

I folded my back seat down, now it will not lock into the up position! I inspected the locking mechanism and it doesn't appear to have anything wedge in there.

I recently took a ride in the back seat of my 2010 Tiguan and noticed that the muffler noise is loud enough to cause headache on long rides. Also I noticed that the back seat vibrates a lot with any tiny imperfection on the road while the front seat you barely feel any vibration on rough roads. Is it only my car?

I recently noticed that my back seat was all wet. It appears water is coming in from the middle of the seat and spreading outward as far as I can tell. The car has been parked outside overnight. All four windows have been rolled up and there is no water in the trunk.

I heard a fan sound coming from the back seat after driving in traffic for 45 minutes. It was coming from the vent in the back seat. I didn't know that that vent had an electric fan. I assume it was the battery being cooled. I have never heard this sound before.

I got some manual of the internet on how to take out the bottom off the back seat. I got it off and installed the seat covers. How do I reinstall the seat. Instructions say attach rear hooks then push down to attach front. I attached the rear hooks but can not just push down on the seat to install the front. Sitting on it does not let it latch on. How to make the front latch on? This is on 2010 Prius. I got the u tubes going inside the white connectors but they will not latch on. Is there a trick? Seat is faom and Styrofoam so I don't want to just push down as I might break something. It's GT covers that I am installing.

I recently purchased a 2009 Camry with 95,000 miles. The Camry was purchased new at the dealer that I bought it from and all of the maintenance had been done at the same dealer so I have records of everything.
I did not notice any rattles when I test drove the Camry but driving it the next day I noticed two rattles. The first rattle was the deck area behind the back seat. That was easily fixed with some card board shims placed the right places. I will do a permanent fix later.
The other rattle was driving me crazy. It did not do it all of the time and to me it sounded "exactly" like it was coming from the area around or in the glove box. I took the glove box and the area around it off and could not find the source of the rattle. I had my daughter drive the car while I set in the passenger seat and the rattle never occurred.
I finally found the source of the rattle. It was the lid for the center console. The lid originally had two rubber bumpers. Both of the bumpers were either missing or worn completely down. When I had my elbow on the center console lid the rattle did not occur. I fixed it with stick on drawer stops.

2011 Volvo XC70. I'm hearing a popping sound similar to a plastic bottle popping coming somewhere from the back seat of my Volvo XC70. This usually occurs while driving a few miles after first starting the vehicle and happens only once. We've check the car for any plastic bottles that may have been lodged under the seat or inside the car and no bottles were found. Where this sound is coming from. There seems to be no mechanical problems associated with it, just this popping sound which is quite loud.

Got my Prius v 5 in June and since then, there is the most obnoxious rattle coming from the back seat (passenger side). It's intermittent, depending on who's in the car with me. When I'm alone, it happens about 80% of the time. When my kids are in the car, it depends on which one and what seat they choose.
I've taken it to Toyota twice, and they're unable to detect the problem. I'm convinced that this is because the weight distribution is difficult to replicate. It is seriously making me crazy and I'm ready to turn the car in and get another (NOT a Toyota).

I have a '10 IV and my drivers seat clicks in the middle of my back. It seems that it may be the top of the lumbar cushion going bad.

I have a 2014 Prius v that I bought new in January 2014. I've had this persistent rattle which seemed like it was coming from the back seat behind the driver. I've taken the rear seat partially apart and glued and shimmed things to no avail. I've emptied the entire contents of the rear storage area and it still rattled on. Anyhow I've had this rattle for six months now. Turns out the noise is coming from under the car just ahead of the rear tire where some body type plastic which juts down about 2". This piece rattles when against the frame just ahead of where one would put a jack for lifting the car. I've temporarily stuffed some old paper napkins, which were handy, between the plastic piece and the frame. Noise is gone! I'll eventually remove the napkins and then load up the area with silicone. I'm doing both sides of the car just in case.

I am trying to remove the upper portion of my passenger seat for my 2012 Prius C. This is not the part that you sit on. It is the part where your back rests against. The part where the head rest attaches to. I'm not sure what the formal technical name of the part is.

The headrest of back seat will bend over when fold down the seat. But one of the headrests can't go back to original up position. The dealer has adjusted the cable but this just temporarily fixed the problem. The problem is back again. I will go back to dealer but can they really fix it? Should I ask for a replacement of the whole seat?

I rarely drive with anyone else in my 2004 Prius. This week we've had out-of-town guests, with two people in the back seat. When the doors are locked, the front seat passenger can pull on the handle to open the door, but the back seat passengers can't open their doors with the handle until someone in one of the front seats pushes the door unlock button. The child safety locks are not set. I keep getting out of my car and forgetting to push the button to let the back seat passengers open their doors. Is there anything I can do to change this rear door behavior?
