Lexus GX 2010+ :: Strange Noise Coming From The Back / Pump Or Something Running Continuously
Sep 11, 2012
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.

The last two mornings I have gone into my garage and have heard a faint "buzzing" noise that seems to be coming from the rear of 2013 RX350. Given the location of the noise, my first inclination was that it was possibly the fuel pump running a cycle for some reason. But when I heard it for the second day in a row, I figured it would be wise to ask if this is normal or something I should take up with the dealer?

Our 2012 camry se had a problem with the fuel pump running when the engine was off. Several hours after we came home I went into the garage for something and heard a humming noise. First thought was a distant neighbor using a leaf blower, then realized it was coming from the rear of car. definitely coming from gas tank area. Turned key on, then off and noise was gone.

I have a 2008 F350 FX4 with the 6.4l diesel, a couple weeks ago I was reprogramming the ecm and noticed the vacuum pump was running and wouldn't stop, so after a bunch of reading and testing i changed the solenoid vacuum valve. I tested all the vacuum lines and found no leaks.

I have a Tiguan 2010 Manual , I noticed yesterday that the fans Runs after 5 Seconds from Turning on the Engine and continues to Run until i switch off the Engine. Everything else in the car is normal , Temp , Oil Temp l Airco ..etc. The only thing i notice is the high noise due to this.

Just a couple of months ago, I bought a 2010 RX350 CPO, and the car seems to have developed a strange issue. When I brake and come to a stop, it sounds almost like a choo-choo train coming from the back of the car. That's the best way I can describe it. A few thumps/chugs spaced apart as I am applying the brakes to come to a stop.
What this might be? Annoying that I already need to bring this in for service, but I suppose that's what I'll need to do. Would seem like a warranty issue, but either way, the dealer better take care of this without charge.

Having an intermittent strange sound coming from the fuel pump from its normal whine at start up to a gurgling sound almost like you are blowing back through the fuel line back into the tank. Going on a 300 mile trip, should I hold off?
Btw: it's a 1996 Aerostar 3.0L

Its been really really hot lately here in SoCal and i noticed something weird. When my car is running with the AC ON I notice this vibration/buzzing from the car. I feel it on the brake and accelerator pedals too. It doesn't happen all the time but its pretty often. I can feel it more when im stopped at a red light. Is this normal?

Our 2013 RX350 makes an annoying thunking noise, coming somewhere from the rear underside of the car, every time you come to a complete s stop, e.g. at a traffic light. I had a test drive with a mechanic from our Lexus dealership, and he told me that every 2013 RX350 he ever drove made that noise. Is that true?

This is the second night in a row that we hear a noise coming from the back of the car. I know that some noises are normal but this is after the car is stopped/parked in the garage for some 5 hours.

2010 SF Limited, about 46,000 KM.
Heard a grinding noise coming from the back of the truck today. First thing I thought to look at was the rotors. They looked warped/wavy and were really hot. I'm worried that the pads are used up and its metal on metal, really looks like rotor damage. I'm confused by this...
1) I get a safety inspection done every time i'm in for service (6km), no service rep has ever warned me about my pads.
2) Aren't squealers supposed to warn the driver of low pads?
3) Pads wear out faster in the front than they do in the back. How could the back pads be used up already? The front looks fine.
So if my back calipers are seized, or the e-brake line froze, then i'm driving with the back brakes engaged full time. This should not have happened to a truck so young. Do I have a warranty case here?

So for about two months I've had a crazy annoying whining noise coming from my back right tire. I've brought it to my garage twice, both time my mechanic has told me not to worry and cleaned the breaks. He has no real solution further than that.
I understand that it might not be something serious, but it's driving me crazy!
It's worth noting that I also need an alignment, with my car steering to the right normally.

I bought a new 2014 RX450H in late December of 2013. The car has 5000 mikes on it now and today when cleaning the car, I noticed (hard to believe but true) 3 separate rust spots coming through the finish on the back hatch panel. I know I need to contact the dealer, but should I be screaming for a new body panel or just accept the fact the my new car has to be repainted? This is the 4th RX I have had. Never ever had a problem before.

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?

I have a 2000 V70/XC volvo with 95K miles. I began hearing a strange hollow noise, like a whistle blowing. I took it to the dealership where I bought the car and they said it was the fuel pump. I asked them if it was bad and needed to be replaced and the said they weren't sure about having it replaced right away. They said sometimes it will make that noise and the fuel pump could last for months and sometimes for years. They even suggested to just drive it until it fails then replace it. some say it could never go out. But it bothers me because it is the car that my wife drives daily taking kids around and running errands and so forth. I am always worried that she could get stuck somewhere anytime. So I am not sure what to do.

Last week while my wife was pulling out the cart . I heard a grinding noise coming from the back wheels. i figured it was time for new brakes, I changed the front last year so rears were pending.
I changed rotors and pads, they were like 20 per left. also looked like the e brake was touching the rotors. I adjusted that a little.
So the noise is still there and its worse. I have no clue what could be making the noise. brake dust shield maybe.. shocks .. Its worse when i turn right...
I have done brakes on every car i have owned and it was pretty easy for lx. What could be causing the noise.

I am feeling disappointed just came out of a lemon law suit with a kia optima I bought two years ago. I figured we'll I should buy a better brand this time which my brother recommended cause I was going to buy another Infiniti I always had good things with those cars. But the last 2 nights I have been hearing a squeaking noise in my rear end of my brand new IS 350 F Sport. Only in sport plus mode. I was driving home from work at 2 am and driving through a canyon road cause I want to see how this car does as soon as the road got a little bumpy I was hearing a squeaking noise come out of the rear of the car. Then I get home and I hear it going over my speed bumps in my complex of my condos. So I think we'll that's odd. I take it out of sport plus mode and back to eco and drive around the complex again and it goes away. Remind you I have 484 miles on the car.

My girlfriends 2010 Golf 2.5 is worrying me. We went on a weekend vacation to Boston so the car sat for 3 days. I go to turn it on tonight and it just immediately stalls. I was like okay thats weird so I turn it back on and instead of stalling, the RMP gauge keeps dipping and then going back up and theres a strange knocking noise, so I turn it off and then decide to try again. Same thing happens so I go to open the hood and the noise is pretty loud. I noticed a strange smell outside the car while the motor was running, but I can't really explain it. So I turn it off for about 2 minutes and then start it again and its just back to normal, I'm so confused. I drove it about 5 miles and it seems fine, aside from idling slightly rougher than normal. What this could be?
