Lexus rattle in cold weather by moeandmo

"My Lexus (ES350) has a cold-sensitive rattle that is evident only when the temperatures fall below freezing and goes away when the car and/or the weather warm up. The dealer tried a couple of times to find it last winter and was not successful. All spring, summer, and fall, the car was quiet. In the last couple of weeks the rattle is back on cold days, and it is embarrassing when friends are in the car. Yesterday the morning temperature was 21, and the rattle (on the driver's side) was VERY loud. . I'm waiting until the forecast calls for several days of cold (below freezing) temperatures so that I can drop it off at the dealer and tell them to LEAVE IT OUTSIDE overnight and drive it cold in the morning. I have been keeping a log of when and under what temperature conditions the rattle is evident. There were days last winter (and again yesterday morning) when it sounded like a cheap jalopy. Last winter, a friend who drives a Jaguar and a Mercedes, was a passenger in my then-new Lexus and said, "What on earth is that noise?" ....that was not a good moment for me. The noise is definitely on the driver's side and does NOT appear to be coming from the dash. The colder it is, the more evident it is."
  
So in a nutshell, if it is very cold, the noise is evident. When the car warms up, the noise goes away. But if the car is stopped and parked for a time (even as little as an hour if the temps are cold) the noise is again evident when it is re-started. It's a thumping, rattling, vibrating sound. When one is driving, the noise appears to be coming from the driver side door or undercarriage, but sounds are difficult to pinpoint, so this might not be accurate. When one is a passenger, the sound definitely comes from the driver's side but NOT the dash.
 
Does anyone have any experience with this?

I have 2000 miles on my 2008 ES350. Last week I took my car to the dealer to fix the rattling problem mainly coming from the windows on both sides. Dealer said they fixed by tightening "something" so the windows would fully slide in to the window gaskets. Car stopped rattling for about a week, but then started again. I also felt a slight bump in the steering as I make sharp left turn into my garage. But then the dealer couldn't find anything

I have alot of experience with this, been to the delaer four times and rattle still not fixed. Definetely coming from the drivers side and louder during cold weather. The dealer tried the following; clips on sunroof, replaced all winshield clips and put felt on the dash mounts. I felt all were nothing but a waste of time, I can tell you don't waste your time with those remedies they won't work for the rattle you describe which is similar if not the same as mine. I feel they rattle comes from under the front drivers side wheel well or under the hood on the left side. I even thought maybe the plastic engine covers make noise when in the cold weather. I'm trying to figure it out myself because the Lexus dealer takes me for a fool with their bogus solutions. So much for a luxury car

Today was especially vexing. Outside temp was 11 degrees. I was going out, so I started the car in the garage and burned off 10 minutes worth of gas warming it up before driving out. The car was quiet. But I parked at the mall and left it out in the cold for 40 minutes. It rattled significantly coming home. The problem I face is that all the coldest weather comes on weekends, and it warms up during the week, with lows staying above freezing, so I can't take it in to the dealer until there is a sustained cold snap so that I can be sure that they hear the noise I hear. And I agree with ronv4. My dealer has also done the same "fixes" that were tried on his car, with the same result....or lack of result. My rattle sounds EXACTLY like yours. When you are driving, the rattle sounds like it is coming from the left front of the dash or door, or undercarriage.

Good news - I hope.
  After the fifth time to the dealer I went nuts on the service technician to the point he actually came to my house and we drove about two minutes and low and behold he heard the NOISE. Loud and clear. The car was just returned to my house and I was 100% assured that the problem is fixed. According to the tech the noise is coming from the roof pillar on the drivers side. They dropped the roof liner and took off the covering to the roof pillar and found metal clips loose that caused the rattling. This makes some sense to me but until I drive it for a week or so I won't know for sure if the problem is fixed.
I will definetely let you know the outcome and I'm hopeful you can benefit from this info as well.

That sounds weird because the rattle doesn't appear to be coming from that high up in the vehicle. Like you, I thought more that it was coming from the wheelwell or undercarriage or door....and why would clips in the pillar rattle only when it's freezing outside?
Do let me know how this works out for you. I'm printing out all this information so that I have ammo when I show up again at the dealer. I'm waiting until we get a forecast of below freezing for at least 2 days so that I can take it in, they can let it sit out, drive it cold, work on it, let it sit out again, drive it cold again. It will NEVER rattle when it comes out of a toasty warm shop environment.

I agree its strange and I'm a bit skeptical but the guy seemed like pretty sure that they solved the problem. Although I do agree with you we need some really cold weather before I can confirm that the problem has been rectified. Fingers crossed.
More to follow.
Take Care

Rain Sensing Windshield Wipers by don90

I have just purchased a new ES350 and I notice that when the wiper switch is left in the auto position the wipers will make one swipe across a dry windshield as soon as I push the start button. I can not predict when this will happen, it may happen two or three times in one day and then it has gone more then a week with out happening. this happens always on a dry windshield, car could be in the garage for a couple of days and when I push the start button as the car is starting the windshild wipers will make one swipe. Have been back to the dealer but they say they can't get it to fail and that they need to see it fail before Lexus will authorize any parts to fix the problem. I was wondering if any other owner has experienced this problem and if your dealer was able to stop this from happening. Any help would be very much appreciated.

We are making progress. We drove from Missouri to Michigan for the holiday. While in Michigan, we took my car to the Lexus dealer here for an oil change and described the rattle problem to them, thinking a fresh set of eyes and ears might see what others had missed. These guys listened to what I was saying instead of just looking at tech bulletins and addressing what they expected to find instead of what was actually there. I might be a woman, but I knew what I heard and I knew where it seemed to originate. When I said the noise was coming from the wheelwell or undercarriage, that's where they looked instead of the dash or the sunroof. And guess what..... they found a broken strut mount, which they replaced. What they replaced is called the Front Suspension Support Assembly. The car sat out in the cold last night. I drove it this morning and it's quiet....no rattle; no thumping. I hope this is the end of that issue. I am pretty confident that they have finally gotten to the source of the problem. I'll know for sure in the next day or so, after driving it multiple times. It's been nice chatting with you ronv4, but on this issue, frankly, I hope we never meet again!!!!!

Back to square one Ronv4. It still rattles. How did your door pillar fix work?
