Touche. Unfortunately this is already being related by the media to the Audi event and they are saying that the Audi issue was nothing compared to the significance of this. Pretty sad.

That almost decimated Audi in the US from what I remember....The Quatro went from being king to pauper in 5 seconds flat.

yet another reason to hate politicians... 

But I will say I hope this is a reality check to Toyota and hope they go back to their old ways of not trying to be the biggest and be the best.  The last thing we need in this country is another Ford, GM, or Chrysler *ahem, Fiat... Wink

Toyota seem to be doing pretty good damage control. Their apologetic commercials airing and 'admitting mistakes' seems like a good play. I think this whole episode WILL definitely impact them for the foreseeable future, and let them realize they are just as vulnerable - if not more, than any other car company out there...

I think this the article someone mentioned above:

Car & Driver:  How To Deal With Unintended Acceleration - Tech Dept.

My view:

1. Shift to neutral.

How that CA highway patrol officer could miss this I don't know.  If the Toyota problem involves the transmission computer too (does it?) then they have an even bigger problem.  It was a rental, perhaps the officer was not familiar with the car (what does he used to drive anyway? a bike?).  Some suspect that the shift gear went into the + - position where you change gears up if you're trying to get to neutral.   If he had taken the time to familiarize himself with the car beforehand, maybe this could be avoided?

http://l.yimg.com/dv/izp/lexus_ls_460_l_luxury_sedan_2008_interior_gearshift.jpg


Now some are claiming that, to protect the transmission, Toyota "may have" disabled the shift to neutral feature in WOT situations.  I doubt that very much.  Maybe each one of us with Lexus/Toyota could test that.  Just go to WOT in a high gear (less torque on the transmission, just to be sure, and it's closer to the situation the CA oficcer found himself in) and shift to Neutral.

2. Apply the brakes.

Note that you shouldn't pump the brakes.  Just press them down hard for what your life's worth.  Pumping makes you loose the vaccum assist sooner, and sice the engine is WOT, the brakes will get much harder to press.  They won't lose any power, they'll just be unusually stiff.  Nothing that a 90Lb person fighiting for dear life couldn't do.

Again, Infiniti cuts the throttle while applying the brakes, but not the Toyota.


3. Turn off the ignition. 

That will make you lose power steering and vacuum assisted brakes, but at high speeds, the effort to turn the car is much lower.

Note that, according to the car&driver article above, a Lexus will take 3.5 seconds of button press to turn off, while the Infiniti takes 2.5 seconds.  Also, in Panic situations, where 2+sec seems like an eternity, 3 rapid buttons presses turn the Infiniti off, but do nothing on the Lexus.  Interesting to know that.

I unfortunately think Toyota is being skewered for this unnecessarily. The govt are using them to set 'an example' whilst in bed with GM (sorry, I don't normally feed into this kind of stuff, but in this situation...)

Toyota have made some mistakes. Their recent media fiasco with the "saving $100M by not recalling..." is definitely not helping the situation, but they are indeed trying to run a business.

The question to me is - is it really a mat issue, or is it really a 'sticky throttle/ECU' issue?


The scenarios above are interesting, but although I do put a lot of stress on my car, i'm not willing to destroy the transmission flat out. I know in my case the brembo's > engine. Smiley

Another issue with this is - you have to be in manual/sport shift mode in order to stay in a higher gear at WOT (otherwise the auto transmission is obviously going to downshift into a low-ish gear). The next problem would be - even if I do this in 8th, in manual shift mode, the car is going to drop down into 5/6/7th at < 41MPH (which I dont consider to be 'runaway speeds' personally.. but)

I could test this on the GS and the LS as well, but alas...... my wallet is already empty enough. Smiley

Makes sense, I didn't want to put anyone else that read my post in big trouble!  Sorry for that, dear lurker, if you already did!  LOL

I should have make more clear than: AFAIK, the WOT situation described above does not mean necessarily the car is redlining, you can be WOT at 2000rpm...Now that you post this, maybe you can shift into neutral from WOT, but *perhaps* not with the car at the the upper most RPM reading.  Maybe that then poses a thread to the transmission?  Not sure how, but then again, I'm not an engineer.

Okay I just did some testing on the Sequoia.  Some very interesting results.

1. I could select neutral from any gear no problem at regular throttle.

2. I did select neutral from WOT (wide open throttle) position in second, 4th and 6th gears, no problem.  I angrily stuck my foot to the throttle with as much force as I could (if it's going to happen, better now, as I'm alone here, straight line, etc), rev raises from say 2000 rpm to 4 or 6 thousand (it depended on the gear, I never went past 60mph), then I selected Neutral (just a nudge up with the lever), what happens is, the car goes to neutral, engines goes crazy free and quickly revs all the way up to the top bouncing off the rev limit @7000+ rpm. 

Actually it didn't feel like bouncing (like on a bike, the engine cuts on/off), so it felt strange, like it was just on an upper artificial rev limit, I then release the throttle and after a while select drive no problem.  Of course I never tried reengaging any gear with the car revving that high.

3. Now I tried to shift to neutral when revving AT the redline, but I couldn't do it because I never reached that point at safe speeds (or the car would simply change gears).  The closest I got was revving @6000 in 2nd gear up to 60mph (I think 1st has too low to try), it did required a fair pull (or I was scared the transmission was going to go kaput right then and there and missed something), but it did went to neutral.  I wonder if you can't go past 6000 in 2nd?  It took a while to get there (but it's a truck, so take that into account), so in a real recall scenario, I would have 3-4 seconds to shift into neutral comfortably, provided that's the first thing I'd try.

4. Now I also tried to shift to Neutral from the same auto position (sport shift mode).  It's much harder to get to neutral, what happens is that it kind of stops into drive, engages the next gear (because your redlining say 2nd), and the car gets speed like I've never seen it doing before (cos' it's not exactly a track car, and I don't high revs at highway speed), I went to like 75mph in an instant (since I got my eyes back on the road to drive the car), then shift to neutral no problem.  Of course, a second time didn't caught me by surprise, and then as soon as it changed up when in drive I also engaged neutral immediately.

5. While practicing shifting to neutral from upshifting in sport mode then simulating being stuck WOT, I accidentally put the transmission into Reverse...

OMG.




I then realized that was just like being in neutral.  Only the car displays reverse on the dash, the rearview camera kicks in (probably the reverse lights too), etc.  This is a very WTF situation if you're not expecting it.  I searched the manual and couldn't find any info on this, so very cool they have this.  CAR&Driver should do their homework better and try this with all recalled cars.  People would stop trying to find neutral and would just go for parking/reverse without looking and be done with it.  Less explaining the better.

I tried that a second time and took this picture:

http://cdn-3-service.phanfare.com/images/external/5413559_2417287_94066409_Web_3/0_0_745e6054fb8249b9cfce8a7ef5e66802_1

Watch the speedo and the shift gear...check the display too.  Funny, huh?  Well, it turns out that, on second testing, I let the car slow down to crawling speed and that's when the reverse kicks in and you start moving backwards.  Of course if you try to go all the way to the Parking position, you'll rear a grinding noise and it won't go further, but that's actually more difficult than just hitting reverse.  So my conclusion is, if your Toyota or Lexus gets stuck in WOT, just move the gear lever to the right and to the top no matter what, as fast as you can.  Don't even look, just go.  You'll find neutral eventually.  I can find neutral from the sport shift mode position with my eyes glued on the road now, time to do get my wife to do the same.   Grin Cheesy laugh


(disclaimer: don't try this if you're not in a closed/deserted road, if you're not a professional stunt man, or a driver with years of experience and if you didn't read the f*ing manual, or if you're just a wuss prone to panic and has no biz. driving a car in the first place.  I'm not responsible for any consequence of you trying any of this, do your own research or just pray this never happens to you.    Cool)
