2020 Acura RDX tech SH-AWD, 2023 Maverick hybrid Lariat luxury package.

Yikes. First incidence of complete brake failure I've heard of here on this board. Had the brakes been acting peculiar in any way prior to the accident? Is your van equipped with the standard ABS brakes or does it have the traction control/VSC?
Was the brake pedal firm, or did it go to the floor?
Any suggestions where I might go for expert help?
I can't imagine they didn't make the system failsafe.
Even on a multi-channel system?
I recently came back from a road trip to Hull, Quebec, Canada. My 2004 Sienna performed flawlessly. I can't explain perfectly in words how satisfied with my decision to get this van. Unfortunately, while parked at the Holiday Inn de Chatiere in Hull, Quebec, My wiper blades were stolen from my van in the Hotel's garage. Apparently, from what I've learned, parts for this van are very low and people are stealing parts right off the street. That was not even the discouraging part to this story. I chalked this up as a loss and proceeded to the local Toyota dealer which I found across the river in Ottawa. The parts department worker after hearing my story told me that the blades for my van were on back-order in his as well as two other Toyota dealers that he called in his area, and that it would take as long as three months. Would you think a little "black-market" parts are showing up anywhere in that area? I then went to Canada Tire to purchase "Rain-X" so as to not damage my windshield with a "non-approved Sienna" wiper blades. I needed the assurance of something for my eventual trip back home. Fortunately for me my trip back was rain-free, and uneventful. After getting back and telling my story to my local Toyota dealer, He told me he had never heard of such a thing, and advised me to write my story to you. Thanks for any feedback you may want to send my way.
Something tells me you'll be able to find replacements easily on eBay soon :-(

also, when i use auto climate control the ac lite is on, is the ac always on, and if i take if off will i fog up suggestions
Thank you.
What could possibly be different about an AWD setup which would allow a CD changer w/ NAV? If Toyota HAD a CD changer w/ NAV, why wouldn't they put it in the Sienna to compete with the Ody setup? Why would they reserve it only for the AWD model? Wouldn't a CD changer be listed in the brochure?
Some salesmen will say ANYTHING to make a sale.
Why can't Toyota make 255hp on regular like the Ody? Well, first, the Honda has a bigger motor (3.5l vs. 3.3l). Second, the Ody makes it's peak power and torque at higher rpm's than the Sienna. Higher rpm = higher hp.
And finally, don't believe everything you read. It is not unheard of for manufacturers to 'fudge' their hp ratings (both up and down) for a variety of reasons. If you are after bragging rights and into bench racing, then by all means the Ody certainly looks better on paper. But one thing the manufacturers CAN'T fudge (as easily) is curb weight. Comparably equipped, the Sienna typically runs around 400 lbs. lighter than the Ody. Even if both engines ratings were perfectly accurate, the actual hp/weight ratings would be essentially dead even.
Bottom line, both the Honda and Toyota run perfectly well on regular. Both the Honda and Toyota will perform essentially the same in most performance tests (to the point where seat-of-the-pants impressions would not be able to detect a difference). Where there IS a difference in felt performance, it might be due to the Toyota transmission acting a bit 'lazier' to throttle imputs than the Honda.
Honda makes more power because of larger displacement, better intake and exhaust system. Quoting peak Hp and torque is not correct. You need to analyze the HP and torque curves. When one does this, they will be surprise to see that the two engines are quite close, but the Honda will continue making more torque and Hp at higher RPM.
I noticed an unusual smell in the van last week. Not unexpected, I guess, with kids. But after it continued, I started to investigate. I figured our oldest had probably left a half eaten apple core in one of the hundreds of storage compartments.
Turns out, I found that the insulation under the carpet in the back storage area (you know where your back seats fold into) was wet. My first thought was that some water spilled after going shopping or something along those lines. But after confirming with the wife that no water bottles had mysteriously come back half empty, I started wondering. This past week, my wife looked again after driving in a rain storm. Now there was a puddle in the back well.
Anyone else have this or have any ideas? There seems to be a round black plastic plug that seems to easily come out and basically opens to the ground (a drain for real spills??). I'm wondering if that's the problem and this really should be sealed better. I don't see any other stigmata of leaks within the van proper. But I am looking for suggestions before taking the van in for service.
Thanks
Which is why the Sienna will retard the timing a bit when running 87 rather than 91 octane. The result being very slight loss of power under full throttle conditions yet will prevent knocking under engine load. Which is why I said that if I were towing something, I would probably go ahead and use Premium to ensure that I was getting all 230 hp; otherwise, using regular is fine. Which is why the Toyota Manual specifically states that 91 octane is 'recommended' for improved performance, and NOT required.
My 01 AWD RX300's transmission fluid has a burned look and odor at just 38k miles. This on a vehicle that has no tow hitch but with the tow package (extra transmission fluid cooler in front of right front wheelwell) and no designated fluid/replenish maintainance schedule.
I have sent at least three missives to customer_satisfaction_inquiries@lexus.com and what I get back each time is that I should check with the dealer about why my RX has burned fluid. Apparently something they do not wish to put in writing.
Up until just this week I have been assuming that the designers underestimated the heating contributed by the VC.
But then I keep hearing/reading about these hesitation problems and that got me to thinking on another thread.
I am absolutely sure that my 01's transmission shifts into another gear, or maybe even neutral, during coastdown.
Some have described it as a "slingshot" effect or as if being bumped from behind just before coming to a full stop. I have attributed this effect to a desire to increase fuel economy and/or reduce the instances of loss of control on a slippery surface as the result of engine braking to the front, drive, wheels.
But suppose for a moment that I'm correct and the vehicle is being shifted into neutral in these instances.
My 01 DOES NOT have an e-throttle so the instant I depress the footfeed the engine will react and apply high output......while the transmission is still in neutral or an inappropreately higher gear??
Now THAT would result in premature BURNING of the transmission fluid!
But now with e-throttle the later models might have a firmware fix that delays the onset of engine torque until the transmission can be shifted into the correct gear and allow time for the clutches or bands to be full seated before excessive torque is applied.
Obviously just guessing, but....
Don't you hate it when engineers make a quick fix just to appease the finance guy?
Penny wise dollar foolish.

I drive in my business a Chrysler T&C, which also claims to have 20.0 gallon tank, but one time I filled it up (it was really empty) and it was 21.0 gallon.
Missed the boat with 20.0 gallon? If it has great mileage you don't need much more. I agree bigger is better, but 'missed the boat' is not the right word... and if Toyota missed it, Honda missed it too with the Ody, which also have just 20.0 gallon.
for Sienna only 7.4 sec? Ody and Quest only need 7.1????? has anyone push any near this?
Best I can do :-)

No, you can do better. If you see a double - or triple - post, just delete it!
Back to the Sienna?
