Lexus LS 2007+ :: 2011 460L AWD - Consistent Vibration When Coasting
Jul 29, 2014
I just took delivery about 2 weeks ago of a 2011 LS 460L AWD with less than 30k miles. I have a very annoying issue that happens every time I let off the accelerator. There is a consistent vibration that seems to be coming from the drive train. It's really annoying to me. This occurs when driving about 50 mph or greater, nothing when driving at slower speeds. There is a 30 day exchange policy where I bought the car from, hope I don't need to use it.

During an extended drive of the new ride today, we noticed an intermittent vibration when coasting downhill around 60MPH. I popped it in neutral and the vibration disappeared completely. Also, it stayed vibration-free when placed back in Drive, without touching the gas. But as soon as throttle is applied and then you coast again, the vibration reappears.
This points to a condition that only happens when the torque converter is locked, which could be a vibration originating within the transfer case that once coupled to the engine via the locked torque converter uses the engine as a tuning fork, resulting in the vibration. The L-SB-0013-12 AWD Vibration TSB mentions an ECM recalibration, which likely changes the torque converter to unlock whenever you lift off the gas pedal. Is this correct?
I also remember reading about the other TSB, where the "magic expensive fluid" in the transfer case gets changed 3 times in rapid succession. This would address chattering clutches within the transfer case, eliminating vibration at the source vs. masking it by unlocking the torque converter.
We also noticed a misfiring sensation under light throttle conditions at around 40-50MPH. I'm wondering if this is in fact the transfer case clutch chatter issue also...since the 60k spark plug replacement has already been done.

This is the third time I am having this issue, previously once it was close to service so dealer just added the oil and few months ago it happened again and I did the 1200 mile test where the dealer measures the burn rate, nothing came out of that. Finally I had it last few days, it was flashing intermittently and I took it to the dealer and they added 2.7 quarts of oil and while I have 2500 more miles to go for the scheduled service. Looks like my engine is burning oil. I don't have any visible leakages as my garage is clean. I will update after my second 1200 mile test. However I suspect nothing will come out it as I have few long drives planned and 1200 milestone will come up fast. I am having this issue if the time between the oil changes is more than 3 or 4 months. My car is 2007 LS 460L.

My trunk won't open from the inside or with the key fob? The only way to open the trunk is by detaching the key and using it manually. What gives....

Just picked up an 08 460L with navigation and was looking to sync my Motorola Droid X. I have successfully paired the phone for voice communications using the instructions in the manual but when I go to transfer my phone book the car just says transferring. I left this for about 10 minutes and no numbers moved. The phone says Paired for audio is this would be my guess as to why this isnt working. Any tips to get my numbers imported?

I have an '09 LS 460 AWD and there is a very unlike Lexus knocking sound at idle to maybe up to 20mph. best way I can describe is to imagine a diesel engine at idle, and dilute it substantially. subtle but clearly there. i read here in CL that could be due to valves or such, but dealer insists it is because of the intentionally designed "oversized fuel pump and fuel injector" and completely normal.

I have an 08 ES 350 and when driving and coasting between 20 - 60 mph, there is a rubbing, grinding, low frequency sound that I feel coming through the gas pedal. What is causing it?

I have been experiencing a bad vibration in my engine during consistent RPM even at idle. It goes away during acceleration or letting off the pedal. I made a quick video.
-Video is still uploading at this point so... 30 minutes or so.

So I'm used to the vibration coasting down from 110-115mph or so, I would mitigate it by applying light throttle. Recently it started coasting in the 75-80 range, then 70-80, and now it does it just plain cruising in that range as well. Nothing below 65, and nothing above 80 (coasting, cruising, or under load).
It's definitely a mechanical vibration, tires are fine, wheels are fine, wheel bearings are new... Thinking driveline u-joints? Don't have the money to throw parts at it unless they're the fix. I've consulted Christina's analysis chart and this is the only thing that makes sense so far.
No other symptoms anywhere else except those ranges. U-joints are, as far as I know, OEM originals. 276k miles seems like a hell of a life for them, especially with the abuse they've seen in the past 75,000.
I need to crawl under and give things a shake and wiggle, current condition is unknown. Left for a road trip to meet the wife's ex so he can have his time with his son, and the X was so bad at the aforementioned speeds that we turned around and swapped vehicles. It was worse this morning than it's ever been and I wasn't risking catastrophic failure with a zero emergency fund.

I have recently developed a vibration between 30-45mph only when coasting. It smooths out when I tap the gas. The tires are less than a year old and I just put new manual lock out hubs hoping that would correct the issue, but it didn't. There's no clunk noise when in reverse or drive but occasionally when I get on the gas there's a short squeaking noise.

This just gets stranger by the month. I could have sworn when I first got this 2011 Sonata that the console read 341 after filling it up for the first time. I thought it had said that after I filled it the second time (just after Hurricane Sandy - yes, before the long lines - I was lucky) and it read 329. On those occasions the console had read approx 67 & 69 miles to empty. I know I filled it with 87 the second time around. The first time may have been with 89. And when it stopped at 14.x I thought to myself, hmm, didn't it fill to 15.x the first time? Weird. So I went on with my life.
This past weekend it read 50 miles to empty and so I filled it again with 87 (same gas station I should point out). And just like the last time, before this time, it filled with 14.1xx and read 288 miles to empty. It just seems to me that "Miles to Empty" has slowly gone down. On the third filling I believe it may have read 303 to empty.
Is it me? I am imagining things here. Could have that much sludge/dirt/whatever it my tank because of the gas station I visited or the 87 and not 89 that I have been putting in? Oil and filter were changed in mid October and then again in mid March. Thats about to happen again on the 28th but also to have the required NYS Inspection done. What should I say to them if anything? Could I have picked that crappy of a local area gas station?

2011 SF. 52000kms.
A little while ago I noticed a brief vibration (felt through floor and steering) with normal acceleration from stand still... I attrributed this to the cold weather and perhaps oil thickening, as the problem went away after the car was warmed up. Since then I have noticed that it's continually happening on a regular basis, but only for a short period.. I was still thinking that it was the cold, but that wasn't the case because I left the car idle at start up for 20 minutes until well warm.
Now.. If I slowly accelerate (not putting much load on the car) there is no vibration at all. When the car reaches a certain speed, the vibration goes away. There is also no vibration after about 15 minutes of driving.
I had a neighbor test it with me to confirm and he felt it, and initially thought differential oil, but then suggested myriad other things from the CV boot to bearings to etc etc.
I need to take it to the dealership so they can experience the vibration but would certainly need to leave it there over night so they can check it out when "cold".

I have an odd sort of occasional vibration in my 2004 W12. I've read the sticky FAQ info posts concerning vibration, but I can't find a report with the same symptoms. Here are the observations:
1. When present, the vibration comes in very mildly at 50 MPH and peaks at 65 MPH, then dropping to barely discernible at 85 MPH.
2. The car shudders under the vibration, at worst resonating interior items and can be felt through the seat.
3. The vibration ceases IMMEDIATELY at any speed when coasting with the throttle backed off.
4. Curiously, the vibration seems to be much more noticeable after about an hour's drive. Before that, not so much.
5. VAG-COM does not indicate any misfires... I was sure I have a bad coil/plug... but the controller shows no such evidence. The throttle-on shake feels like a miss.
6. Brakes on/off makes no difference.
7. Road surface does not make any difference.
8. Near new (2K miles) Yokohama YK 580 all around, stock rims. If it's balance, I doubt it would decrease at higher speed (being sub-critical). Likewise for belt bubbles or other tire flaws.
Some posts have pointed to worn suspension link bushings causing mechanical resonance at certain speed ranges, perhaps aggravated by engine torque on the mounts, so I'm leaning in that direction (bushing replacements) if nothing else comes to light.

Symptom: A vibration that feels somewhat like a bouncing tire
Cause: Coasting in Drive (Applying the gas at all stops the vibration, putting the car in Neutral also stops the vibration)

I am having problems with vibration on my 2011 Santa Fe 2.2 CRDi Premium, 95% of the time the car is fine, but twice now in the last month, out of nowhere, I can be driving along as standard and all the sudden a vibration will hit the whole car out of nowhere, it almost feels as if there is a bleb or defect on one of the tyres, the whole car shakes, but the shake is not coming through the steering wheel, it is the car body that seems to be shaking, if that makes any sense... However, if I pull over, turn off the engine, restart it, and pull away the vibration immediately disappears???
I am totally lost, as it is a occasional occurrence I can not replicate it for the dealer to inspect as it is still under warranty...

I have a 2011 RX350 and like car for the most part. Something strange I have noticed is that the gas pedal seams to have some little vibration when I am pressing it smoothly. My foot is constant on the gas pedal maybe 1/4 of the way down and it doesn't feel smooth like other vehicles. I have a 2014 lex IS250 and it doesn't have that vibration. Also had a 2004 RX330 and it did not have that vibration. It is a slight vibration that ruins the luxury driving experience.

I noticed recently that on my 2007 Camry i4 @ 110k miles, engine rattles pretty noticeably when I have the AC on AND while on reverse. Once I either turn off the AC or shift to D drive the rattle is no more. This noise is pretty consistent.
Not sure if this is a common problem, but could this be a problem with the water pump/alternator?

I am a first time Toyota car owner. I bought a 2010 Toyota Corolla LE this past Saturday. It has only 42,000 miles on it, and I got a pretty decent deal on it! I'm still getting used to how the car drives, but it seems to be running great. The only thing I notice sometimes is that I am coasting downhill (not using the brakes) I notice a bit of a vibration sound coming from what sounds like the back windshield. If it keeps occurring, I might take it to the dealer for them to check it out. With my luck, the issue might not even happen though with them there.

My a/c has been slowly but surely going out. When it worked it would blow cold air, but it would slowly decrease the force that it would blow until almost nothing came out at all. Now it wont even turn on. The cabin air filter is new, the lights on the a/c and circulator are both on. I think the compressor is still turning on too. I did notice that occasionally it will make a quick hiss noise, but it happens fast, not a consistent hissing noise.

I am considering the purchase of a 2008 LS. After conducting research I've noticed that there is a common issue around an odd vibration problem at certain rpm and around control arm bushing's with these cars. I've also noticed that there is a common issue around air suspension issues. I based my conclusion around threads that seem to pop up constantly.
