Lexus RX 300

  • I was driving the RX300 in a really bad Bay Area rainstorm this morning. There were several occasions where I could feel the car drift, and like the fronts wheels were getting squirrelly on me. This after losing control of the car in a moderate turn about 6 months ago after a fresh rain. Luckily I was able to correct and get out without any damage.

    This car has me scared, more for my wife and young son. Has anyone else had troubles driving this particular vehicle in the rain, or is it the Goodyear Invicta tires? This is a 2WD 2000 model and does not have VSC.

    Thanks!

    I will be traveling from N.J. to Calif. in July I usually change the oil every 5000. I will probably only have 8000. on the car by June, Do I just change the oil or do 10k because I will miss it. I plan on changing the oil again when I get there in Fresno. Also should I use 10w30 since it will be hot on the road and I will be traveling high speeds and interstate driving.Thanks everyone.

    In my 01 AWD RX I have noticed that when turning on a rain slicked street I oftentimes hear something as if I have a large tree branch dragging along under the car. I have susepcted this is the result of the VSC detecting slight under-steer and moderately braking the rear wheel(s).
  • My '00 RX has 25,000 miles on it. It started making noise, kind of clicking noise, when press brake pedal gently. I can hear the noise in low speed, and can duplicate the noise all the time by backing out of the driveway.
    My '01 Camry, 20K miles on it, has same noise.
    I don't think this is normal. Anyone has any idea?

    I had my 15k service done at the Toyota dealership yesterday. I have 17k miles but of that 3000 was freeway so I guess its ok.

    Total for Oil change+tire rotation+ inspections=$25. I supplied them with Mobil 1 + filter + seal. Tire rotation is $10. I had it done to Lexus manual specs (using the spare page 280 of the 2001 manual).

    No loaner car/no free coffee/cookies but for a $400 price diffrerence I dont care. Took about 1.5 hrs but watched my RX thro the glass windows so it wasnt that bad.

    For my last oil change, they used up all the 6qts. Now, it used up only 5qts. I am worried with this. They drained the oil, so it should use the same amount right? So how come only 5 qts now? Is the remaining 1 qt sludge??? My daily driving (5 days a week) is a drive from my home to the Park & Ride that is 1.5 miles each way- pretty bad for the engine IMHO

    Washed my car. How do people in cold weathers wash their car? The cold water made my hands numb. But I did it out of love for my car ;) Its all worth it but if there is a better way I would like to know. The first few times I would shampoo my car all over before rinsing and never got a clean look. Finally I figured the problem was that the car was drying up (with the dirt on) and not being cleaned. I washed 1 panel at a time and got a clean finish. All products (shampoo/wax) were Meguires (the 6 pc kit from Costco for $15)

    What do I use for perforated Leather? I know this has been discussed often but too lazy to search.

    What about swirl marks? Any 3M products?

    I also plan to use Zaino once summer sets it, but it looks like it never will be here in Seattle.

    No apology necessary. I didn't think you were being mean or condescending. Lexus owners generally are cool folks. Thanks for the info!

    Check and see if you're clicking noise isn't coming from near the base of the shift handle. Solenoid mounted there to keep you from shifting out of park without applying brakes.

    Oil change w/ filter on the RX requires 5 qts. of oil.....not 6.

    My Rex just rolled 31k, and while it was serviced a few weeks ago I got a brand new FWD loaner. This thing felt like it had twice as much "go" as mine. Now I've noticed that before, but in direct comparison, it seems to be unbelievable. One of my theories is that the adaptive transmission has built a mean over time (lots of highway) which doesn't reflect the actual driving style any more. I asked the SA to have the trans' memory "zapped", but the tech forgot. He explained that I only had to disconnect the battery for a few minutes to reset the ECUs in order to empty all storage.

    Has anyone noticed the same behaviour on their car? Where else could this originate, or am I just a victim of my imagination...?

    I had the same experience when I had about 40,000 miles on my RX. I thought it may have had something to do with needing a tune-up. I mentioned it to the service tech and nothing came of it and soon forgot about that experience. That's a good thought about the transmission. Let me know what happens if you zap it. Other than that and the radio and clock settings what else will be lost?

    I guess the memory seat setting will also be lost.

    ...my service advisor told me that after the 30k service I would see instant improvement due to the changed transmission fluid and such, but, as usual, he was wrong.

    I'll try my theory in a self-test, if you don't see any post within the next three days - remember me as The brave one...

    I used to disconnect the battery (or just the PCM fuse) on my 300M whenever it learned some bad tranny habits. It worked.
  • wwestwwest Posts: 10,706
    I always felt that my car drove easier, smoother, after I washed and waxed it.

    Ya'll don't think the (if memory serves) 250# wt difference between AWD and FWD affects your perceptions, do you??

    Certainly you can zap the ECU but you still have to deal with a heavier car and a drivetrain with more frictional loss.......but I know wifey's AWD feels much more "on rails" than the FWD with VSC loaners I've had, even before the switch from No-Integritys to CrossTerrains. I've got my GS430 when I want to rub somebody's nose in it.......
  • tariktarik Posts: 344
    Yeah, for "rubbing" I drive the 'Cuda...

    The weight difference between the FWD and the AWD is there, no doubt about it, but what I experienced was more like jumping off the line more instantaneously - almost like torque braking before you let go.

    Let me zap the ECU while SWMBO looks the other way.

    Ahhhhhh......got HemiCuda???

    My post didn't reflect it, but I have experienced the livelier feel that you mention when driving a dealer loaner. Mentally I attributed the difference in off the line "snap" both the weight difference and the added driveline friction. I hadn't considered the ECU "learning" (though I knew/know it does) as a factor, so I'll be interested to read of your experience. Just, of course, how the car performs and not the sordid details of what happens when SWKAMBO (She Who Knows....) finds that you've messed with the innards of her beloved RX.........;)

    ruski - do you know the location of the PCM fuse for disconnect to "zap" the tranny (as mention in your message #4738)? How or what is it labeled in the fuse panel chart?

    Might not be a bad idea to zap this every now and then to improve performance.

    thanks!
  • gsenthilgsenthil Posts: 154
    Do you think the FWD loaner has more zap because loaner cars were driven differently than personal cars...and the "learnt" ratios were hence different?

    I wish I had a HEMI, but could I justify to drive it as my everyday car then? I currently put between 1000 and 1500 miles a month on mine, which is a "real" "cuda with the 340 engine. Mopar enthusiasts want to strangle me for that all the time, but if it were a HEMI I would be long gone...

    Regarding SWKAMBO (thanks for the correction - makes sense, doesn't it?), if you don't tell, she'd never know . Hope I don't need the Rex towed afterwards.
