Lexus GX 2010+ :: Loud Gurgling Type Pump Noise When Removing Fuel Cap
May 19, 2014
I'm getting a loud gurgling type pump noise when removing the fuel cap. It is really something I have never heard before on any vehicle. It's not a quick hissing noise. It is a constant motor type noise coming from the fuel filler. I tried it again today because the dealer was there, but since I have a 1/2 tank of gas it did not happen.
Each time I have needed to fuel up, I've heard it. So I suspect this noise occurs when the tank is low...within 3-4 gallons left.

I bought this Subaru used with 350 000 km's on it,and I haven't added that many kilometers to it yet at all. For some reason whenever I drive on the highway and get my speed up to about 120 the front left part of the car (somewhere underneath the hood I believe) starts to make a loud gurgling type of noise. I know that the suspension on that front left tire is missing, but I don't feel the rumbling on my steering wheel and I don't think it's coming from there.

Problem started when the fuel supply was low, she had to floorboard it to get on the interstate, keep getting cel, misfire #4.....I replaced fuel filter, had a little water causing the plug to arc....had a mechanic replace the plug.....at startup cold, cel is off and it doesn't miss, after it warms up, light comes back on and starts to miss. I have ran every type of fuel cleaner in it, even used a three step cleaner for throttle body, vacuum system, and tank. I just poured sea foam into the tank and trying that, I noticed a gurgling noise when I removed the gas cap. I'm thinking #4 injector is stopped up.. I recently replaced all the coil boots.....kept getting condensation in the boot (she has been washing the underside at the car wash).....the truck has the 4.6 and has 85,000 miles, it is an 07 sport trac.....

I go to get fuel tonight as my wife gets home with "that" look on her face. Car is at a quarter tank. Go to pump put in the nozzle and start pumping. The nozzle stops and I can hear gurgling from the tank. Here is a pic of how much goes in. So I now pull the fuel nozzle out a tad and proceed to keep putting gas in slowly. Here is a shot.
After I do this the car takes more fuel and I continue until I can see the small bubbles. Understand that fuel is not leaking anywhere. Its not coming out of the sides or anything. I am also not filling it up to the point in overflows out. Here is a pic of the total fuel when I am done.
Is this normal? I have to do this every time. I noticed on a 987-S Boxster I had the tank did not vent properly cause the same thing would happen. Trick I would do is rotate the fuel nozzle 180 degrees up and it would fill up completely. I tried doing this on the Lexus and it didn't work.

I just had a new evaporator installed in our 03 Gx 470, and now it is making a gurgling, bubbling type sound while the air conditioner runs, it almost sounds like air is in the system.

2003 f550 with 7.3, suddenly loses power and struggles while driving. White/blue smoke comes from tailpipe, can smell the diesel exhaust bad when happens, comes and goes intermittently but has been happening more and more often. I uploaded a video onto YouTube to show sound, rough running motor and smoke from exhaust although smoke not that bad in video. Search "shadetreelandscaping" on YouTube in case link below doesn't work.

Took to ford dealer a few diff times for problem and they can't get any codes, can't duplicate problem. After it being in for third time they say had to call ford tech hotline and they suggest replacing injector however can not and will not gaurntee that will solve problem, and obviously dealer isn't cheap for repair. I find it hard to believe that a bad injector(s) would be an intermittent problem as it is or that it would cause fuel pump to make gurgling sound.

At only 51,200 miles, it looks like my fuel pump is starting to go bad. Making way much more "noise" than usual.Guess this is what happens when you drive around with the gas tank on "E" half the time. $262 at 1st VW Parts.

Over the last few weeks I've been hearing what sounds like a failing pump of some sort when shutting off my '06 GX470. The sound lingers for just a moment after the ignition is cut off, and sounds like a loud, very fast tatatatatatatata. It doesn't always do this - sometimes I don't hear anything. I've been commuting in the GX for four years and I've only been hearing this intermittent occurrence over the last 3-5 weeks.
What this might be? Fuel pump? Air leveling suspension pump?

I just bought a 2010 corolla xrs. I'm wondering what type of fuel it actually requires. The manual said 87+ octane but everywhere that I read online is saying premium is the way to go for max performance. Is this true??

This started yesterday. A Loud grinding type noise from the top of the engine. As soon as I touch the throttle the noise goes away. I checked the pulleys and TC and everything checks out. Sounds like it's coming from the HPOP gear area like a gear train noise. Maybe the additional oil pressure has something to do with the HPOP inside getting quiet.

We bought our 2010 RX last December--dead of winter--and never noticed this until this week, when the temps are approaching summer, like upper 80s.
The AC (and heater) fan makes a loud droning noise (low frequency, but quite loud) when the "auto" setting turns the fan to one of the two highest settings to cool the car down. Never noticed this until now because the fan never ran at the higher settings in the winter (parked in a heated garage). It makes no difference which vent setting is used, the loud drone from the fan is the same as long as it is running at the higher speeds.
Also, I'm NOT talking about the fans in the seats. This is the big fan behind the dash. Manually decreasing the fan speed reduces the drone, which becomes almost inaudible at lower fan speeds.

I bought my RC F new about a month ago and have put a very fun 1450 miles on it. Ever since I got it, there is this weird noise happening right at about 2.8k - 3k rpms. It doesn't seem to happen when I'm hammering on it as much as when I just accelerate on the road to get around somebody and peak at those rpms.
Not quite sure how to explain the noise, it's kind of a high pitched gurgling. Is this normal?
I tried recording it but you can't hear it through the video at all. If you turn the volume up and put your ear right next to the speaker you *might* be able to hear it. It's much more apparent in real life.

Our recently purchased '04 V8 Touareg is increasingly sounding like a jet turbine engine upon start-up, and especially as winter approaches. We're told it is probably the DC-powered fuel pump. Any way to reduce the aural effect?

My buddy's 94 Grand Cherokee with 5.1 L has developed a loud grinding noise. I thought it sounded like a wheel bearing but the shop said, "front differential, transfer case, and possibly drive shaft."
Does it sound feasible to remove the drive shafts to and from the transfer case, to see if the noise disappears (indicating transfer case and/or shafts)?
If it is the front differential, how big of a job is it to change the whole unit out? Could it be a bearing in the differential; inner axle bearing, or carrier bearing or something?
It is a work vehicle, and he doesn't want to sink big repair into it.

The other morning I went out to the garage and heard a strange noise coming from the rear (underneath the 3rd row seating/storage area) of my GX460. It sounded like a pump or something running continuously. I was in the garage for 10 minutes and the noise had started before I entered the garage and continued after I left. When I went back out to the garage 3-4 hours later it had stopped so I am not certain how long it was running for. I previously owned a 2006 GX470 with the rear air suspension and this was not the sound that was coming from my new GX. The car had not been running or driven in over 8 hours and I am at a loss as to what it could be. I figured I would check here first before delving into the 700+ page owners manual to troubleshoot.

Just drove 60 miles and parked the car. loud whine coming from the fuel pump area. and the exhaust smells a hell of a lot different. Smells like fuel in the exhaust. Stage 3 kinetics kit. stock exhaust. Upgraded fuel system.

Odd, relatively loud "whoosh" noise when they turn off the engine? It sounds pneumatic in nature, like a pump or servo of some sort sealing or depressurizing? I should note that I park in a garage, which may amplify it. Definitely more noticeable if you open the driver door or window then kill the ignition.
Second, I don't know if it's the cold, a bad batch of gas, or just normal but the motor seems to make a clack clack clack noise when stopped/at idle. It's not consistent and doesn't seem to affect drivability. I just hope it's not knock or slap, i.e., indicative of serious issues. Am I just being paranoid and overly sensitive?

Our 2013 RX350 has a brake pedal that makes a pretty loud noise when it snaps back after you depress it a little harder and take your foot off. I complained to my SA, and they told me it's normal. It's not a big deal, but any other car I have owned, I have never noticed such a thing.

I recently noticed that when I release the parking brake on our new 15 F-Sport it make a loud noise. It's hard to explain, but it kind of sounds like a spring being released with a clunking sound. (Sorry for the weird description).
When I press the brake to set it I am not pushing it all the way to the floor or forcing it at all. I am just using normal pressure to apply it.

Just picked up a new 2014 rx fsport and 75% of the time I release the e-brake it has a loud clunk as if metal smashing metal. I tried releasing it really slow and it still does the same. The vehicle is parked on flat pavement. It is not a low click noise that I am used to but a loud clunk.
