#124 of 305 Looking for Mud Guards for 2005 Gs-300
Apr 29, 2006 (12:16 pm)
I have a 2005 Lexus Gs-300 that is white in color. Every time I wash the car I am finding the sides of the car are covered in tar that shows up easily on white. This takes about 1 hour to sit down and remove all of the tar. I have had previous Toyota products that have had factor mud guards that I can not seem to find for my GS. So was wondering if any one had purchased mud guards for their 2000-2005 Gs that fit like factory?

I have a 98 GS300 with the same problem; I have been told that the cause is due to faulty MAF & Throttle Position sensors, in which either one or both send wrong signals causing inproper shifting. I have not yet fixed my car, however, if you decide to proceed with replacing the sensors, please let me knowif that fixes your problem.

My GS300 AWD was purchased in August-05. I love the car just like you did on the first 10,000 miles. After 10,000 mile service, dashboard starts to make noise. I did notice the car starts to feel vibration on or about 8,000 mile. The vibration is increasing every day. It seems the car does not have damping at all. After 16,000 miles, I switch to Michelin Pilot A/S tire with softer compound compare with OE Dunlop RFT tire. Car is still shaking up and down or side by side. It will send all kinds of road feel to make you feel uncomfortable. The vehicle should be smooth and solid.
I also experience similar B.S. from Lexus dealer telling me it is what is designed. I told them, I will never purchase this car if the uncomfortable ride is started when it was new. No matter how you tell them. They always tell you it is normal. One day when the service advisor told me that I am not the only customer who complaint about it. Still after another test drive, the statement still list the ride is the same as new. What a joke!
Can someone tell me is it the damping or bushing (Stability bar or shock absorber) problem?

You may want to get the front-end alignment checked. I have a 2004 GS430, driven mainly by my wife. Handling was excellent initially. The first time driving in light dusting of snow, car was all over the road. Dealer laughed it off, saying that the car is very light with a big engine so we should have expected that. So much for Lexus being attentive to safety. Bought a set of Dunlop Graspic winter-only tires, and that improved winter driving. Pain to have to change out the tires each fall and spring, but that's life.
After the second winter, when we put the OEM tires back on, the car was extremely unstable at all speeds. Independent tire shop reported that the tires had an unusual wear pattern (slight cupping - can't see it but can feel it) which indicated alignment issues. Problem was present on both the winter tires and the OEMs. Back to the dealer, who agreed, and did an alignment at no charge. (BTW - Dealer said that alignment on the GS430 has to be done both for the front and the back. ) They also reported that my tire shop had put the tires back on in different locations than the original installation (this could be BS, I can't tell. Doesn't seem like that should make that big a difference). Dealer said that the tires will even out with use, and the ride should improve further.
Bottom line is I now have two sets of VERY pricy tires that are stil usable but somewhat compromised.
The car STILL does not handle as well as it should, possibly due to the wear on the tires or other yet-to-be-found issues. For the price of a Lexus, it seems to me that the suspension's ability to stay robust and stable is not what it should be.
Wife is no longer confident in the car's overall safety or ability to handle properly (esp in emergency) and so we may replace it with an Acura or Infiniti, or bump down a notch to Honda.
Overall a very disappointing experience dealing with Lexus on this. When we've seen odd behavior of the car (weird handling problems, erratic acceleration and shifting), the service writer ALWAYS says that it's normal for the car, unless we have a report from a third party (like an independent mechanic).
So much for my rant. Hope you have better luck getting the issue settled. I recommend being very aggressive with the service dept at the dealer.

I'm surprised you thought a rear-wheel drive car with a big engine and wide performance tires would handle well in the snow. That's the nature of the beast and has nothing to do with Lexus' concern with safety. If you drive in snow with a RWD performance car, you need snow tires.

RWD vehicles, even those with high performance engines, are much safer overall on adverse roadbed surfaces that their FWD or front torque biased AWD counterparts.
Just because, like 4WD or AWD, FWD will often initially get you up and going quicker/faster isn't an indication that you can stop or turn more quickly to help avoid an accident.
Once drivers of RWD vehicles learn how to feather the throttle (or Trac forces the issue) RWD vehicles tend to be safer overall since the front tires' contact patch is always dedicated to directional control. On the other hand if you drive a FWD or front biased AWD without a clutch then the AAA is currently recommending you practice and learn to quickly shift into neutral in the event you have an incident wherein loss of directional control is threatened due to engine leading or lagging torque.
More importantly this discussion started out being about the GS AWD model. The dynamic allocation of engine leading or lagging torque represents a significant design break through insofar as safety is concerned.
and watch the Honda video about the most perfect modern day AWD system in existence. Then watch it again and pay attention to when the engine leading or lagging torque goes into rear biasing in order to provide a more safe driving experience. The SH-AWD's engine compression braking mode should be most enlighting for FWD or front biased AWD advocates.
#130 of 305 HELP- 2000 GS300 NEEDS $4,000-$8,000 IN REPAIRS

Hi- I purchased a 2000 GS300 platinum series back on 11/15/03. I have only had it serviced at my local Lexus dealer. It now has 96k miles. Back around 93k on Oct.27th 2005 (about 6mos ago) I had the timing belt/waterpump/thermostat changed. Last Friday I dropped it off at the dealer complaining about a whistle/chirping sound coming from the engine and I thought it may be a belt (though the drive belt has been replaced 2 times n/c!!) Anyway they typed up a n/c invoice and said they "thoroughly inspected all belts and pulleys, no part at fault, could not duplicate customer's concern". I picked up the car Monday night. The very next day while I'm driving about 20 miles per hour, I hear a loud thud. The alternator actually fell off and was dangling by some wires. I towed it to the dealer. They claim the studs/bolts broke off and the alternator fell. This caused a domino effect. The bolts on the Alternator broke, the alternator belt wrapped around the crankshaft pulley, which tore the timing belt cover and caused debris to get onto the timing belt gear, then causing the timing belt to jump timing inturn causing the valves to hit the top of pistons. The total cost of the repairs is $3700 for "phase 1" this estimate does not include the replacement of engine heads if needed, which could result to a completed total charge of aprox. $7000-$8000.
I am looking for mechanics or anyone who knows anything about alternators and how they are mounted, to reply back with their opinion on how the studs could break off and could this only be caused by human error. Like I said this dealer would've had to take the alternator off about 6mos ago when the changed the timing belt. They claim the problems would've arised before 6 mos if anything was going to happen at all.
Sorry for the long email. I am in tears and beside myself. I am still financing this car and can't imagine paying for a car that I can't drive. Lexus Corporate is agreeing to pick up 30% of the tab. If I'm lucky I'll get the other 70% in court.

What a mess. You should definitely consult an attorney on this. Dealers have "malpractice" insurance, and your attorney could line up expert witnesses if he/she thinks there is merit to your case.

I was scanning this message board for this problem, which I just encountered on my 02 GS300. I bought used about 1 month ago and I have had this happen to me twice in the past week!
It's a very strange feeling to have your car turn off when you come to a stop!
What did you end up having to do to fix this problem? Does it get worse over time?

Wow, a thousand bucks right out of the gate? What is a throttlebody anyway, it's not underneath the discombobulator, is it???
As I mentioned in an earlier post, I just bought my first lexus, a used 02 GS 300, a month ago and this has now happened to me twice. The car seems to turn off as I come to a stop at a traffic light. No problem restarting, just very weird feeling!
I believe my car is officially under warranty until next february -- would this be a warranty issue?
Thanks for your thoughts on this!
