Oil Consumption by memreo
May 06, 2008 (2:52 am)

I own a 2006 Lexus GS 300. I have had many of the same problems as others regarding tires (replaced four at 15,000 miles) and rattles in the dash (most started after the warranty ran out).
 
My local dealer is the only place this car has ever been serviced. All oil changes are completed every 3000 miles by the dealer. My car currently has 59,000 miles on it and at the last oil change (57,000 miles) I got a low oil warning light and message on the dash. I added two quarts of oil and took the car straight to the dealer. I was told that if this happened again, not to add the oil, just bring the car to them. This past Friday after only 2000 miles, I got the same warning light and message on the dash. The car has been at the dealer for two full business days and the best they can come up with is that high compression engines use up to one quart of oil per 1,000 miles. For some reason, I find this hard to believe. The only other car I have owned that had this kind of problem was a 96 Sedan DeVille with the Northstar engine. Anyone have any thoughts??
 
At the last service, dealer replaced fouled plugs---which makes me think this is an internal engine problem.

High compression engine oil consumption is B.S. Must have a cracked ring or something internal. Service dept should be able to find ...... warranty ??

The dealer is not charging me for anything at this point and all receipts show as warranty. They are telling me (as of yesterday) that the trips I make in the car are too short and the engine never really gets a chance to warm up. I live at least 15 miles from my office and drive the car quite a bit during the day in town. I think they are trying to cover themselves at this point. With only 59,000 miles, I hate to get rid of the car, but I also hate to think that I will need to carry a couple of quarts of oil in the trunk. I also know that this is going to get worse.

Wet Carpet in 2001 GS 300 by geunger

I have a 2001 GS 300. My wife had a VW Beetle that got water in the carpet and started smelling bad. The other day she told me that the Lexus was starting to smell the same. We checked, and the carpet on the passenger side (front) was wet. I had my son remove the mat, which was also wet, and soak up as much water as possible.
 
Today I asked my wife if the carpet was dry, and she did not know, so I checked. It was very wet! However, only the carpet directly on the floor is wet. If you check the front of that carpet, either side, or the part under the seat, those sections are all dry. All of the other carpet in the car is dry.
 
We suspected clogged drains in the VW, and after we cleared them that seemed to solve the problem. However, I can't see any clogged drains on the Lexus. It has rained pretty hard here the last two days, so I suspect that the water is coming in when it rains, but I just can't see how.
 
Any ideas?
 
Thanks.

If the center of the carpet only is wet, one would have to suspect the sunroof, which is the only drip location that makes sense, right? A clogged sunroof drain could cause such a leak.
 
There are two types of clogged drains as well. One beneath the fresh air vents (under the wipers) and another that drains off condensation from the AC. This drain might leak from behind the console to the center of the mat.

I thought about the sunroof, but if it were actually leaking there the water would fall onto the seat. The sunroof is well to the rear of the carpet. It does not appear that the sunroof is leaking in any case.
 
When I put water into the vents below the wipers on the passenger side, it ran out a couple of places on the bottom of the car. The hole that is apparently the main drain outlet had some debris in it, so I cleaned it out. I suspect that was the problem. The outlet hole on the driver's side was pretty much clear. It does seem like the water runs through some cracks on both sides in addition to the main vent hole. When I put water in the center vent below the wipers it also ran out of a hole in one of the (metal) "channels" that run along the bottom. I suppose this is normal, but I don't know for sure.
 
We just had a cold front come through or I would check the AC condensation drain. It will certainly get hot here (central Texas) shortly, so I can check that later.
 
Thanks for the help. Much appreciated.

Did you have your windshield replaced recently?
I had the water leaked underneath the dashboard on the passenger side after having a windshield replaced for a couple
years on my 89 Accord.
The leak was not severe so I didn't do anything. Then the next
windshield replacement fixed the problem.

The windshield has not been replaced, but I will do some additional checking around the seal.
 
We took a long trip yesterday with the air conditioner running the whole time, and we did not get any water in the carpet. So I'm pretty sure that's not it an AC drain leak.
 
Thanks.

Does the leak only happen when it rains?
How's about put some paper/newspaper on the carpet to see where the water
drips?
