Lexus GX 2004-09 :: Sunroof Rattle / Tranny Slip Under Certain Conditions
Jul 5, 2011
Took vehicle in for two things last week and they said both were normal for the vehicle.
1. Sunroof rattles. I can physically push up on the sunroof and feel a little play in it. It doesn't leak or anything, but does rattle on certain roads. Dealer say it's tightened to standards and within normal expected specs for the age of the vehicle (2007), but after feeling the sunroof in my other car that has no play in it whatsoever, I'm a little skeptical.
2. Under certain conditions, the tranny seems to slip/pause and then grab a gear. It happens on off-ramps usually. I let off the gas to slow down and the give it gas to carry me through the off-ramp. It feels like a clunk or the tranny slipping trying to find a gear and then it finds one and noticably clunks in. Dealer hooked up a computer to it and it says it's operating noramlly and the clunk is just a product of the way I drive and the electronic shifting computer. I've had my drive shaft replaced thinking this was the problem, but it's still there.

I've owned my 2004 GX since last November and it has a had an issue with the sunroof in the last couple months.
The problem is my sunroof rattles when it is closed and I have already taken into my local dealership. The first attempt was to lube up the gasket, which worked temporarily. The most recent attempt was to remove the sunroof and realign it as they said it was higher toward the rear of the car.
It seemed to have worked, but now the rattle started up again slight and it will probably progress to get louder. If I push up the sunroof, there is a slight play toward the front of the car. The rattle when driving seems to be coming from the between the front and rear seats so what is actually causing the noise. There is a slight rattle whenever i close the driver or passenger side door.
The service manager said that the GX's have this common problem and that there will also be a slight rattling from the chassis flex. At its worst, I could clearly hear the rattle driving in a straight line, while slightly steering left and right. I know the GX is a truck and not a unibody chassis design, but I would think Lexus could make quite sunroof for this luxury vehicle.

Burning oil smell but can't figure out where or why.
No Drips (checked standing on dry ground).
No Drips (checked after spraying water down on ground).
Checked Oil, level doesn't change.
Checked Transmission, level doesn't change.
Only thing that has changed is that i went with a 5w-40 oil about 4000km ago. Could it be burning minute amounts of oil during driving under hard conditions (mountains/hills)?

I have a rattle in my 2004 Lariat crew cab with sunroof. The sound seemed to come from the rear seat, but I finally tracked it down to to roof of the cab. The back dome light (and interior roof) has sagged some and I guess it's the dome light or wires are rattling when driving.

I recently bought a 2002 Accent with the 1.6 auto 133000 miles. I have been reading the postS around here about the crappy transmission. My car seems to have some life in the tranny still but it has slipped from 3rd to 4th gear around 45 mph when i get on the gas too hard. Its also a little sluggish to start off. My question is should i change the fluid out knowing i have a slipping issue? The reason i ask is that last time i changed the fluid and filter on a Jeep that was slipping i ended up having to rebuid it. Is that a real possibility if i change the fluid in this Hyundai?

I have a Suzuki forenza - whoops! Anyway it is a 2007 automatic with about 25K miles. It started doing the following: while driving it will seem to slip into neutral and rev. For example, driving on the freeway at 65 mph; foot slightly on the gas it seemed to literally jump out of gear and the rpm shot up for a few seconds and then jumped back into gear. It also some times seems to clunk into reverse when backing up and occasionally seems to be in a lower gear than necessary when driving - revving while staying in gear - literally like it is in a lower gear than necessary. It has a 7 year/100,000 mile power train warranty. I took it to the dealer and they said they needed to replicate these things themselves before they could do anything about it. They would not just take my word. The service manager also said that it could be the computer system as opposed to the transmission itself.

I'm at 5,500 miles and the last couple of mornings I've had my tranny slip and lunge between gears, sometimes 2nd and 3rd and once out of 1st. I know there's an update/flash that needs to be done but my build date says not required. My truck was finished April of 2012. I'm going to call the stealer but I'm sure they will "check it out" and say nothing's wrong so it would pin point this issue.

I have the dreaded slip yoke clunk, I used the FORD SPEC PTFE lube and it works for a while until the tranny fluid that makes its way onto the slip yoke dissolves it!! Replacing the slip yoke with an updated one?

I have a 97 f150 (built 96 as 97 model), 4.2l 4x4, auto tranny. Here's the problem, when I turn my key forward to run position my starter kicks on and starts the truck, and stays engaged. I have a constant 14v at the signal wire on the starter relay (yellow red stripe). Also tranny started to slip, od light flashing. I replaced ignition lock cylinder, ignition/ starter switch, starter relay, starter, and today transmission range sensor (neutral safety switch 8 pin), same problem. Cel code that I had 2 days ago was P0707 tr sensor low input.

I have 142k miles on my 2005 RX330 AWD. This week I can feel the transmission slip/shudder when shifting from 2nd to 3rd gear.
My local transmission guy is pretty reasonable but like most salesmen he's going to say rebuild it the entire transmission in lou of something less invasive.

Few weeks ago I bought my first Lexus, an '07 GX 470. It has roughly 75,000 miles on it, 2 previous owners before me. Anyway, I hear a noise sometimes which either sounds like a slight belt slip or fuel being pumped into the injectors when I give it a good amount of gas and the engine downshifts to accelerate. I had the dealer replace the drive belt(serpentine belt) because of 2 reasons, it needed to be replaced and I thought that could be the problem(I did not have to pay for it since I have had some problems with the Lexus dealership I bought it from, they did it as a "goodwill" gesture, that's a story for another thread) and inspect the tensioner and pulleys, they said the pulleys and tensioner were in good working order.
I drove the GX home tonight after said replacement, and I still noticed the same noise. The best I can describe it is like I said above, a slight belt slipping noise or it could also be described I guess as fuel being injected under acceleration as soon as the trans downshifts to accelerate. I am just curious if this is normal for this engine or do I have a possible problem? It's covered under the Lexus used car warranty for another 5 months so if there is something wrong, obviously I would like it fixed under warranty if something is wrong. One thing I should probably mention is, the noise is semi quiet and I guess the average person might not even notice it.

I have this rattle from the tranny at idle in park. If I blip the throttle it goes away. I'm guessing a heat shield vibrating or something....I seem to recall my Corrado having a similar sound at idle.

My Mom has an '04 RX330, and the other day the sunroof randomly opened, and she closed it with the button with no problem. For the last 3 days, this has occurred randomly (opening only - all closing is by her) and all occurrences are when she is driving (not parked).
I told her to wrap the fob in foil today to remove that connectivity and to see if the fob is to blame. We will replace those batteries anyway as I don't know that they have ever been replaced.

I pulled it out last week to fix my aftermarket reverse monitor, so when i pulled the console i tested the light make sure i didn't screwed up anything. Then it was turned on for 2 seconds and slowly died. Since then, none of the button work !!! no sunroof, no homelink, nothing.
I've checked fuse already, 27, 35, 36 I believe. i replaced them all, still not working.

When cruising down the expressway we heard a noise coming from the closed Sun roof. The wind would pick up the front of the sun roof causing a lift / close noise. When I push up on front of the sun roof with my hand it does move it's not locked tight shut. It's annoying to have to listen to.

I was getting a low speed rattle and isolated it to the sunroof. Basically if I slightly lift it the rattle goes away.

So my 2000 1.8t is about to go into its 7th year and for the most part is doing very well. I have a rattle in my sunroof that is driving me crazy lately and I want to get it fixed. It looks like something with the plastic off to the sides. Nothing appears to be loose or out of place.

Looking for info about taking the info/control screen apart. I have a very small amount of moisture that only shows under certain light conditions.
