You are in the Toyota Venza
What is this discussion about?
Toyota Venza, SUV

You should consider the Venza. Its 20" wheels are perfect and give a smooth and noise free ride. I have been driving this vehicle for past 2 months i haven't faced any transmission problem and am getting a good fuel avg aswell on 3.5L V6 AWD.
The dealer from whom i bought the venza has given a lifetime limited powertrain warranty at no cost.">link title
Definitely the HID is a plus with Auto high Beam Feature specially for night time driving
you can look at my review as well on this linkhttp://www.edmunds.com/toyota/venza/2009/consumerreview.html

Was your previous vehicle RWD or R/awd...??
If so then the manufacturers are not being so careful about reducing the level of engine compression braking and the CC calling for a fully closed throttle would/might have more effect at retarding roadspeed.
But even an older FWD or F/awd may have more engine compression braking with a fully closed throttle. It's really been fairly recently IMMHO that manufacturers have begun to pay more attention to this issue, the DANGER, granted, only potential DANGER, resulting from engine compression braking on the drive wheels of a FWD or F/awd vehicle.
Most CC designs will automatically switch off if the engine cannot maintain the set speed within 5-8MPH. Going up-hill the CC is free to downshift the engine to attain more torque since TC would quickly "step-in" should wheelspin/slip inadvertently result.
VW is now protecting even FWD manual transmission drivers from this effect. Downshift too radically such that engine compression braking results in wheelslip and the VW system will automatically up-rev the engine in order to quickly abate the danger of loss of traction on the front, stearing, wheels.
So my best answer to you is pay more attention to your roadspeed going downhill with CC on. And as the manual states "do not engage CC if the roadbed is slippery or suspected to be so.
Perhaps we will soon see the F/awd Venza versions with a slight overdrive to the rear wheels and thereby the ability to "switch" the majority of engine torque, lagging in this case, to the rear and therefore CC downshifting automatically would not represent such a great HAZARD.
On the other hand CC's control firmware, even "today", could be programmed to moderately brake ONLY the rear wheels with SAFETY.
Since the advent of the TC system's capability to independently apply braking to ANY individual wheel or wheels I have wondered why a light to moderate level of braking, actual driver braking, doesn't occur ONLY at the rear. Seems to me that might improve the safety factor of ALL passenegr vehicles.

Thanks dear... I am crystal clear. Got your point. Really appreciate. So there is nothing wrong with my venza
My previous Mazda cx7 was awd 2007 model

2007 CX-7 F/awd...
I would have thought that the CX-7's detuned/derated I4 (low CR to accommodate BOOST) would have yeilded a lot less compression braking than the Venza's V6.
How bad was the CX-7's FE with that detuned I4...??
But your CX-7 F/awd used water cooling to keep the PTO from overheating and thereby possibly more adequate use of rear drive coupling than the Venza. Otherwise that share the same F/awd design. It will be interesting to hear how the Venza F/awd system does in comparison.
Oct 02, 2009 (9:48 am)
It seems to me that a FWD or F/awd such as the Venza, Highlander, Sienna, and Lexus RX series would be highly inappropriate for most Canadian drivers.
The poor safety record of FWD in adverse wintertime roadbed conditions is bad enough but then throw in the unwarranted additional confidence, over-confidence, level of F/awd drivers and you're asking for real trouble.
Kuddoes to Toyota for adopting a more appropriate F/awd system, virtually an exacting copy of the Ford and Mazda F/awd system, and now the Porsche 911 R/awd system.
The only time the rear driveline is to be engaged usefully is under initial acceleration from a dead stop. This is to alleviate, pre-emptively alleviate, the potential for engine torque at low speeds resulting in front wheelspin/slip. Loss of directional control leading to an accident.
Otherwise the engine torque will be primarily routed, 95%, to only the front wheels and TC, Traction Control will rule.
If front wheelslip/spin should then inadvertently result then TC braking will be INSTANTLY used to regain traction at the front as quickly as is possible while at the same time the engine gets dethrottled and the rear drive clutch fully engaged.
Dead in the water, right..??
Unless you can disable TC...
But then with TC disabled will the system still automatically couple in the rear drive or will the owner need to provide a manual switch with which to engage the rear drive clutch...?
The Mazda CX-7 uses water cooling of the PTO such that the rear drive can be engaged, sometimes fully engaged, somewhat continuously. Ford, on the other hand, chose to revise the firmware to reduce the functionality of rear drive coupling in order to alleviate driveline component overheating (once it was discovered to be happening), primarily the rear drive clutch and the PTO.
Given the history of Toyota and Lexus F/awd systems, all mostly non-functional, designed only for marketing purposes, I would put my money on the Venza not having enough F/aw functionality to suffice unless you live well SOUTH of the snow zone.

What poor safety record? All the cars in the ditch at first snow fall are 4WD SUVs.
Got a link?

I have the same problem. To reproduce it just apply a little excess pressure on the brake peddle when starting the car or when changing gears from park to D or R. It triggers the VSC and jumps into gear when the VSC clears. I consider this a very dangerous situation and am discussing with Toyota. Had it back to the dealer abut 4 times before we figured it out. Once we did, we could reproduce on every Venza on the lot. This should be a recall item in my opinion.
#1153 of 1243 2009 Venza Test Drive
Oct 06, 2009 (2:57 pm)
I test drove 2009 Venza (V6 w/AWD) yesterday and noticed a few issues with it, not sure if some of you had the same observation.
1) There was a burning smell outside the car after the test drive and the salesman mentioned that it was because the car was new and still needs to break in.
2) The cargo area with the trunk closed and the second row in position is not that great.
3) I always position my elbow either on the door or door handle, did not find a good position in this vehicle and the leather seats we not comfortable.
4) 20" wheels are way too big for this vehicle.
5) Too expensive for a Camry Wagon.

Saturn VUE is affordable. It doesn't have the burning smell nor 20" wheels.
I don't have the same observation like yours. I love every bit and driving my VENZA that I accumulated 15000 miles within 6 months.

You seem to love your Venza so much that you cannot tolerate others observation. BTW, nobody asked for your advise on which vehicle one should buy.
I am planning to buy 2010 RX350 in December but since I read from various posts that Venza is a good vehicle and in comparison with RX350, I thought of checking it out and post my observation. I am not trying to explain to you but to others who may get offended by my post. "I am not here to trash Venza but for good input from sensible owners".
