Actually, there are ppl out there get confused with the ECT snow mode. Maybe, the salesperson also forgot to go over the feature with them when they took delivery.
QUOTE from the Edmunds discussion board for RX 330:
ANYONE ELSE HAVING PROBLEMS DRVING IN SNOW? by lovingmylexus Dec 26, 2004 (8:31 pm)
I have the RX 330 and its less than a year old. We live in a very snowy climate and my Lexus is AWFUL in the snow. I have the all season tires, 17 inch and LITERALLY if I go to stop and there is a tad bit of ice the car does not stop. I have tried driving in 1,2,3 gear and still the same problem happens. Anyone else experience slipping problems?? I am scared to death to go out in the snow and ice now! HELP!
Thanks

Actually, the ECT button should be used in snow/icy conditions. When selected it reduces the throttle response, e.g. if you floored it with the ECT button pressed the vehicle should not take-off as usually. It helps to prevent wheel spin. Plowing through deep snow, I am not to sure about that, I tried that with about 8-12 inches of wet snow and got about 12 feet into my driveway before the vehicle would not go further, and yes it was the AWD with the Limited Slip Differential rear end.

As I said, I don't understand the science of this. But, my experience with the ECT is the exact opposite of what you describe. For me, having the ECT mode engaged when driving on ice and snow is much, much more dangerous than leaving it off. It helps when plowing through snow piles but makes ice even slicker than glass when engaged.

You are correct. I tested the snow mode in a local parking lot after noticing that the RX wasn't stopping well on ice. The parking lot was basically a sheet of ice. When the snow mode was engaged... the RX acted like a skater on a skating rink. In my youth I would have loved it but I didn't like the idea of skating around a parking lot in my Lexus. I immediately performed the same test without the snow mode engaged and the RX was much easier to control and stopped with very little problem. The symptoms described in the previous post are similar to the ones I experienced when I tested my own RX.
I have used the snow mode when trying to get up our unplowed street after 8 inches of snow. It does help when I first accelerate but I turn off the mode once I get going.
I must say I was surprised because I thought the snow mode would make winter driving easier. Personally, I have concluded the snow mode isn't necessary on my AWD but it is when I drive my husband's rear-wheel drive sport sedan.
I'm confused..... by wwest Dec 29, 2004 (12:23 am)
I wouldn't have thought that ECT snow mode would have had any adverse effect during stopping or coastdown on a slippery surface....
I would have thought that the RX, in snow mode, would start off in a higher gear (it does) and maybe a little detuning of the engine. I would also have thought that in snow mode to prevent too much engine braking on a slippery surface the transmission would not downshift as quickly, remain in the higher gears for a longer duration during coastdown or stopping.
It sounds as if the opposite is true, too much engine braking during coastdown/stopping especially in snow mode.
Makes no sense at all.
And now this, coupled with the hesitation issue, makes me wonder if the Toyota engineer in charge of software/firmware specifications has gone off his nut.
Kinda makes me glad my next purchase is a BMW X3.
I'll likely be back after Toyota straighteneds out these kinks.

Exactly my point from earlier. I re-read the manual after my experiment and concluded that keeping ECT snow mode engaged while braking was the reason why the RX skated on ice so easily.
I do think this is confusing. Our Mercedes has a "winter" mode...and it is supposed to be engaged at all times during snow and ice driving. So, that's why I engaged the ECT button and kept it on until I realized that I had almost no braking control with it on. I think Lexus should either redesign the button or have more than one sentence about it in the owner's manual.
So? by bennb Dec 31, 2004 (3:38 am)
What should a guy do in snow? Have it engaged or not?
Re: So? [bennb] by lovemylexus1 Dec 31, 2004 (10:28 am)
I say no. This is based on my own experiences. It may not be the "correct" way in the eyes of Lexus but their engineers are not in my car when I am driving on snow and ice.

I am so pleased to read this as I had exactly the same problem with the same vehicle. I thought I was over reacting. I am a former diver ed instructor who trained drivers in advanced driving maneuvers (skid control, etc.) and I could not control my Lexus in the snow. This truly shocked me. Thank you so much for making me feel better. By the way, last night I traded it for a 2005 Nissan Murano. My husband has the Murano and had no trouble in the snow.

Sorry to hear you traded your Lexus. But, thanks for checking back in. Now I don't feel crazy for having the what I think are the same experiences you did.

Yes I have the AWD and I hate it at this point I am ready to turn my car in for a Subaru!! I just read the posts about turing the ECT button off and I will do that and see if it works any better.
I didnt see any problems with driving but when you need to stop at a light or a stop sign watch out because its not gonna stop!
To be continued.....

I am glad I am not the only one, I swear my family thinks I am bonkers for talking about it but in truth its a really terrible car in the winter and seeing as I live in the snow belt I need a car that will get me through the snow. I will try the suggestions of turning the ECT button off and see if that helps any, otherwise I am trading it in, its unsafe in my book and I have a 4 yr old in my car at all times and I am not willing to risk her life or mine

Let me tell you how lucky you are to not have problems. I am not scared to drive in any weather but after the last two experiences I have had I will tell you that if the roads are not completely clear I will not drive this car, its that bad......

We have had two big ice storms in the past week. I have had no problems driving my RX on the ice. My ABS brakes have only engaged one time in the past week and that was when someone pulled out in front of me. And I have had ZERO problems with slipping, sliding or stopping. But, as I mentioned in previous posts I do keep the ECT button off.
My RX is the best vehicle I have ever driven in winter weather and I now know I will only buy AWD vehicles in the future.
