View 2 RepliesSeveral times I have gone into my garage to hear a weird noise coming from under the rear of my car, almost sounds like a small air compressor, like one you would plug into the cars power source. If I start the car and immediately turn it off the sound stops, otherwise it will continuously run. The sound does not always present but when it does the car is completely off and the key is not anywhere near it.
Here is a video, you may have to turn up the volume, the video is dark as it was shot from under the car. [URL] .....
I've noticed a couple of times with my 2014 Luxury edition a noise coming from around the spare tire area when the vehicle is parked and shut off even for several hours. Could this be the air shocks?
View 1 RepliesI have a 2003 SC430 with 170,000 miles on the odo. When at idle, the car shakes a little. I notice it the most when at a red light. But if I put the car in N, the shaking goes away. It happens with the most severity when in D and with my foot on the brake. I'm assuming the shake is normal for a car of this age and mileage, but i'd like to eliminate it.
View 10 RepliesExperienced a buzzing noise from left rear wheel well. I have noticed it a couple of times after the car has been parked in the garage and sitting for awhile. The dealer said it is normal and the auto suspension readjusting. However, it will continue for a long time but will turn off if I start it up. I am concerned this normal leveling will burn out the motor in do time. We have a 2010 premium.
View 9 RepliesI own a 2003 SC 430 w / 133K miles. It has been serviced regularly since purchased. While driving in rain , only the engine may suddenly growl and shake. No check engine light or other warning lights illuminate. When I pull over and restart the engine , it runs fine again. There are never any such problems when driving in dry weather conditions. What the issue might be?
View 4 Replies2002 SC430 with 50k miles. I have a set of aftermarket Dolce rims that are 18" with the stock size tires. I have the eccentric spacers on them as well. They have been mounted and balanced. I also have a set of Dunlop snow tires on my stock rims. Obviously I do a seasonal change over.
With either set of tires I am getting a steering wheel shake at 60-65 mph. By 80mph its gone and the car glides perfectly. There is no pulsation in the brake pedal and there is minimal wear on the pads. Below 60mph there is no issues as well.
Tires are wearing evenly. Some roads will make the movement worse, but it always goes away at around 80 mph.
Now both sets of tires were mounted and balanced by the same shop. I assume that could be it...there machine is faulty. But I would like some other possibilities before I try somewhere else.
Several months ago one of my 20" toyo tires was flat when I came out of work. Being a high school teacher, I thought that perhaps it was a students involved situation. That came as a surprise in that as a teacher of over 37 years, nothing has ever happened to any of my vehicles, while parked at school. Also I found it strange that they would let air out and put the chrome valve cap back on. Well, over the weekend, the same thing happened, with the car parked in my garage. So in both instances the tires went flat, I filled them back up and they held air. This happened months apart.
View 6 RepliesI am stationed in Europe at the moment and my wife has been driving my car.
She last drove it a week ago and when she got in to drive last night it would not start - Not even a "click". Interior lights worked, radio etc.
Could be the battery of course with not enough voltage threshold to even engage starter solenoid.
But I was looking for other things she could check before I come back in 3 weeks. I will deal with a battery replacement then if required.
She confirmed car is in "park".
My wife's 04 GX deflates sometimes when we park it, you can clearly hear a loud "whooshing" noise occasionally when we park it in our garage. The rear then goes to the lowest possible setting, it looks odd laying that low. Because it's not my car, I don't know if it always did that, but it seems "new" to me.
The deflation sound is coming from the rear mounted compressor on the rear driver side, I went under the car to investigate. It also appears that the air bags themselves aren't leaking, I raised the car to the highest setting, and it stayed there without the compressor kicking on or any leaking noise.
My guess is maybe the sensors need to be replaced, the thing is, I don't want to "shotgun" parts at a problem and spend $500 or so dollars on new sensors to experiment. How do I know the rear is behaving correctly?
Over the past year I have been hearing a noise coming from the rear of the car. It seems to happen when the car is running and almost sounds like the fuel pump priming itself, but it happens when the car is running. So I don't think it would be that.
It doesn't happen all the time, it might but I miss it due to the loud levels I tend to listen to the stereo at.
My other thought is that it might be from the one of the top motors to raise and lower the roof.
Recently I've noticed that my Automatic Headlight Leveling System has been acting strange. The headlights are constantly "scanning" up and down when driving and even when parked. other drivers are flashing me thinking I'm flashing them. I get the ALS error light on the dash rarely, but it always comes and goes, but the lights are always jumping up and down. I went to Lexus about a month ago and they said they didn't find any errors with the system. So they let me go with no charge. I finally made it in for a true diagnostic workup as the problem still continued, and after a diagnostic fee I was told that my Front Left Ride Height Sensor was failing.

Click
Headlights do not dim at all
No crank
This has happened three times now, about a month to six weeks apart. Eventually it starts exactly like normal. I can't put my finger on exactly what I did between "not crank" and "crank like normal" but it wasn't anything significant, that's for sure.
Tonight I cleaned the battery terminals, but they actually looked very good. Looking back, I should have checked how tight they were before taking the cable off, but I didn't. Not sure whether a loose cable could explain these symptoms.
I was thinking this was starter or solenoid? Any other diagnosis consistent with the symptoms?
I have had my '02 SC since 2007 and frequently when I turn the key to start, I hear an instantaneous "electronic click" sound. I have ignored it and no service person has ever mentioned it, nor have I requested a Lexus diagnosis.

View 3 RepliesI have this strange creaking almost a sharp cracking noise coming from the rear part of the roof near my head when I go over some bumps. I have tried all the usual methods; lubricating roof rubbers, adjusting bump stop under package shelf; adjusting roof height using the grub screw adjustment; nothing seems to work. It almost sounds as if the noise is coming from some of the hard plastic roof trim but I can't seem to pinpoint it despite using foam padding, silicone spray etc..
View 3 RepliesTake a look at the video I recorded with my phone and you can hear a thumping or clunking noise coming from the rear driver side tire. The phone was held upside down sorry!. I'm thinking it's either the brake pads or wheel bearing?
Please try to ignore the wind noises. = Just want some idea so when I take it to a mechanic it would be easier to identify the problem. [URL] ....
I put brand new pads on my 2003 sc430 about 6 months ago, and have noticed this rubbing sound coming from all 4 tires. It is very noticeable and annoying. I'm wondering if I should have put brand new rotors on the car while I was changing the pads. I did not here this noise prior to changing the pads.
I'm attaching a link of a video [URL] .....
I just got it and the gauge is showing a little hot. I took it in they found nothing. The fans runs almost all of the time. It even started running when I was sitting in my driveway with it in park (it was about 55 degrees outside at the time). I also hear some grumbling noise in the dash on the drivers side. It sounds like something is trying to work (the radio is off and it still makes this sound).
View 5 RepliesI have 18k miles on my IS350 AWD Fsport. Brought it in for shake at highway speeds around 70-80. Dealer called and said steel belts are showing on REAR tires on my ALL Wheel Drive. My mileage is 2/3 highway. Went Hankook Ventus V12s on my 2IS and fronts would wear much faster...
