Lexus - Sts :: Exploding Sunroofs When Driving On 50-60mph Speed
Mar 29, 2007
Was on driving doing maybe 50-60mph and suddenly heard this loud pop coming from my roof. Sounded like something exploded.
At first I thought someone had actually landed on my roof!! Saw debrises flying off my roof from the rearview mirror.
Open the sunroof shade and realized a huge hole in the middle of the sunroof!! I had to close it cuz the smaller pieces of glass were falling. What would've happened if I had the sunroof open?
I've read somewhere that the NHTSA is investigating Scion's sunroof shattering. Wonder if this is related to Scion's??

My 2002 v6 camry is shaking while braking on a downhill at highway speed 60mph. This started yesterday. Afterwards on level surface and lower speed no shaking. Late yesterday, again on highway downhill, more shaking.
I live on a mountain and do not notice the shaking coming down at 30mph, including yesterday.
A couple of months ago the pads were 75% and the rotors were resurfaced approx 4000 miles ago. And the rotors are the third pair if i remember correctly.
I bought the car new and it has 121000 miles on 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.

Turned the key on my 2002 MC SS, V6, 3.8L, and the Intake Manifold exploded.
Intake Manifold Exploding on a GM V6, 3.8L? It sounded like a 12ga shotgun. Fortunately no one was looking into the engine compartment at the time as they likely would have been killed given the amount of shrapnel from this explosion. Note that the explosion was powerful enough to blow off the oil cap, which is screwed on with very thick threads.
The vehicle was at my mechanics at time and in his forty years he's not seen an intake manifold explode save for those residing on Top Fuel or Funny Cars.

I was driving my mother's 05 GX (non-kdss suspension).
The steering seems to be quite loose at speeds above 100kph (60mph).
There is also a vibration at these speeds (likely relating to balance).
How tight is your steering?
If alignment/balance doesn't fix things, what other parts might be the culprit?

I'm getting some vibration and steering wheel shake with my '04 GX... I have a 2004 GX with the differential dynamic damper installed. About 55-60mph it starts, and shakes the steering wheel back and forth. Sometimes it's completely smooth, but on other road surfaces it shakes. On full "comfort mode," the shake is much worse, but on Sport mode it dampens the shake to about 10% intensity, but it's sometimes still there. This is not bump steer, by the way.
So far, I've done:
-Brakes
-Alignment
-Front hubs
-2x wheel balancing with 2 different sets of wheels/tires
-lubed the drive shaft and prop shaft to fix the clunk (Clunk TSB has not been done)
-changed the power steering fluid
-checked all control arm bushings, ball joints, tie rod ends, and sway bar bushings. All are solid.
I recently jacked up the front end and moved the wheels back and forth by hand. It seems like there is some looseness coming front the inner tie rods. However, I pushed and pulled and can't get a clunk or anything. I think it's coming from inside the steering gearbox. My VIN says it's before ST002-05, so that TSB aka "Steering Flutter" would apply, if it is that.
After 104k, are the front shocks due for a change? It does seem to nose-dive a bit on braking, but the shocks aren't leaking or anything. Would worn shocks cause steering wheel flutter on these trucks?

In the last couple weeks, once the car starts moving the Speed Dial button dims. Does this also on our 2013 RX350. I've had the car for a year and I can't believe that its been this way the entire time. I'm so certain it recently started. I had to revert to clicking the Call History button sometimes.
I feel it either corresponds to update to iPhone IOS 8 or iPhone 6. If that is the trigger, I'm surprised the Speed Dial is not controlled by the car vs the phone.
I was at Lexus service yesterday and they think its working as expected. Why would one not be able to click Speed Dial, but be able to click Call History and then taking eyes off the road to look at the screen and scroll to find a number!!!
One of the lexus folks was in the car and paired his phone that was an older iPhone and was not OS8.

So randomly my sunroof has begun to rattle terribly when driving at 70+. It only rattles when closed, if I have it in the "up" position there is no rattle but obv then u get road noise.
I looked as well as I could down into the tracks and felt around and couldn't see or feel any loose screws or anything so I'm stumped.

My new LS460 AWD 2008 is jerking on 60-80KPH(37-50)MPH, when you driving without any acceleration.
I have only 900km on odometer. And it's started jerking from 0. I gave my to Lexus for a test. They tested it over 7 days, and now they are saying nothing is wrong with it. And it's normal for AWD version.( WHAT???? )
They have one more new AWD 2008 and it has the same jerking issue.

How to fix the low speed brake squeal on my GS. I have an o6 with about 80K on it. Have had it for four years and never winter driven. I am debating trading it off on an AWD GS or putting it into full time service as my year round driver.
I haven't driven a rear wheel drive car in the winter for 20 years. Everything else I have is AWD of 4x4. Here in Alberta we get some serious snow and ice. I have Nokian WR2 tires on it year round because you can get snow in the mountains even in July. I tried mine on the driveway after a good snow fall and even on Winter ESB and with good tires, it does not seem to have great traction.
Have any of you used your GS430s in regular winter driving, heavy snow and ice. How to get it to perform its best in deep snow or very slippery roads?

I drive 07'es350 and I have felt jerks while driving usually when accelerating or slowing down from speed. Did check with dealer before for transmission after analysis by technician he said it is perfect, recently read on internet and saw fuel filter can be an issue but when called the dealer he said filter is in gas tank and it is lifelong. Not sure what kind of diagnosis I should do to find the issue.

my 2006 GX has 95000 miles and recently i've noticed a slight hesitation followed by a slight surge in speed while driving at a constant speed. it almost feels like i'm pushing the accelerator then releasing it. its a very mild difference but i'm guessing tranny and have 5k left on my warranty. it occurs at a variety of different speeds but most noticeable at about 35-40mph and up around 55mph.

I have an RX 450H and noticed that there is a squeaking sound coming from the dashboard. I looked at other posts where people were experiencing similar issues and noticed one post where someone had a GS 450H and fixed this issue by adding felt between the dashboard and the windscreen.
I would like to know whether this method works 100% and whether I can apply this method to the RX 450H. The noise becomes worse when it is cold and especially when the car is being driven over rough road surfaces and speed bumps.

I am in search of a SC430. I know that from 02-05 it has 5 speed trans. 06 and newer has 6 speed.
Is there a big different in the drive? I just want to justify the extra cost for the 06 and newer.

Just had my prius for a little over a month now and I ran over a nail, had the tire patched. Once I started to get back on the road, the wheels would shake when I go over 60mph. Ive had the tire balanced plenty of times and replaced the hubcentric ring since I have after market wheels on them. The wheels are 17" drag dr31 wheels. I am still having the issues, will replacing the tire fix the issue? The tire is located in the front drivers side.

I put on Cayenne 19" wheels with the high performance tires during my 5K checkup. After 4k more miles I noticed a slight vibration above 60mph, which normally indicates an alignment problem. As I never hit a large pothole or curb, I took it to my VW dealer, (VW of Springfield, VA). They managed to get VW to pay for the alignment, as my it was off when checked. Nice!!! My VIN # was 13,9xx.

What RPMs do you usually have on the highway with your accent? I'm driving a 2009 Accent GS and I'm running at ~2.8-3.2k around the 60MPH mark. Is that high? What do you all run at 60mph?

I am currently running 8mm ECS spacers in the front and 17.5mm ECS spacers in the rear. My Summer set up is still stock BBS RC's, but my winter wheels are Lenso's.
Last winter was my first winter running with the Lenso's and had no issues. This past weekend I swapped out the BBS's for the Lenso's, and now I am feeling vibration above 60MPH. I felt no vibration with the BBS's. I just took them in to get balanced (maybe a weight fell off-idk), and they were within 1/4 of 100% balanced. They then thought it may be the spacers I'm running so they cleaned them up, but said that it didn't work.
My alignment is also spot on-so that's not an issue either. I am at a loss as to what would make me feel that vibration after just changing out the wheels.

My 2000 Toyota Echo has a strange problem. At 60 mph (+/- 5 mph) the temperature light starts flashing. If i slow down it stops. Coolant level is fine. Car doesn't seem to be overheating. Radiator fan is working. With radiator cap removed coolant is not moving when the car is cold, but heats up and circulates as the car gets to temperature .I have heat in the cabin.

My Mk4 R32 has been in the shop for a week now. My number 2 cylinder began sporadically misfiring on the highway and then once I turned the engine off and then back on it would run fine until I got back on the highway and began to accelerate up to about 60.
Took it in and the mechanics couldn't replicate the code. Got a vacuum tube replaced and and it ran fine until I got to the highway. Same issue.
At this point the fuel injector has been replaced and its still throwing the code.

I have a 2005 Subaru Outback, 3.0 H6, LL Bean, 5 speed auto. 150,000 miles. No engine codes.
I bought it took two years privately. I didn't notice during the test drive, but it has a shake/shudder at 18-20mph and at 55-60mph. Only at those speeds and only during acceleration. During light acceleration it isn't noticeable, but hard acceleration particularly on a hill at 55-60 the car can shake quite violently. Probably 50% of the time the 18-20mph shudder doesn't occur. It feels like the whole of the front of the car is shaking from side to side.
It doesn't matter what gear it's in - auto/auto sport/manual 1st, 2nd, 3rd, 4th, or 5th. So it's not engine rpm related. I've had the transmission fluid flushed. I've had two sets of tires. I've had the prop shaft replaced. It still does it, and it hasn't got better or worse. It happens both during straight line and turns.
The engine runs smooth and the gear shifts are crisp and smooth. Our local dealer doesn't know what it is (they suggested prop shaft) and our highly recommended local transmission shop doesn't know what it is. All CV joints have been checked.
I think the big clue here is that it is very vehicle speed dependent; 18-20 and 55-60mph.Could it be something to do with the transfer clutches? Does this transmission have an electronic control computer that needs an update? (This is a first year model). Is there vehicle speed sensor used by the transmission that could be bad but that wouldn't trigger an engine code? Unfortunately I can't disable the rear wheel drive like on the 4 speed transmissions, there is no fuse to do that.
