Replying to: wbay (Nov 15, 2004 1:19 pm) You know it makes absolutely NO sense to me that some have this hesitation problem and some like myself don't. I tried to reproduce it in a large empty parking lot by going 15 -20 mph and making either a sharp left or sharp right turn and then flooring it and it had no hesitation at all. I'm grateful I don't have it but the question is, why don't I and many others have the same problem. I currently have 5500 miles on my '04 HL.

Replying to: desertguy (Nov 15, 2004 2:18 pm) I can only report that I've driven two HL's and both had the "problem." I wonder if there's a possibility your 04 HL was built before the drive by wire system was being installed. Anything in your owner's manual?

Replying to: desertguy (Nov 15, 2004 6:43 pm) On my '01 you can look above the gas pedal under the dash and see where the cable enters the cabin and attaches to the pedal. I imagine on a fly-by-wire HL a variable resistor or something would be attached to the pedal along with an associated wire harness.   On rare occasions my '01 exhibits hesitation and thus I don't think it's caused by the introduction of fly-by-wire (too lazy to check previous posts but thinking other pre '04 owners experienced the problem too), although its possible the problem is exasperated by the introduction of fly-by-wire.

Replying to: desertguy (Nov 15, 2004 6:43 pm) Also, I test drove an '04 when it first came out and didn't notice any difference in acceleration-related issues (I did notice right off however the increased power of the newer 3.3 V6), so I think the issue is rooted in the driving characteristics of the driver rather than the vehicle itself (though this is only a theory and I don't rule out that there indeed is a difference between HLs, possibly linked to the "brain" of the system learning driving habits and "adjusting" vehicle performance). These driving characteristics may be too complex to sufficiently document here in order to reproduce the problem consistently.   I remember in the first days of driving the HL that I found its shift points to be somewhat awkward and acceleration a little sluggish, and I adjusted my driving habits to compensate and eventually it became a subconscious act. Others may have different expectations in how a vehicle should respond and may be less tolerant of its idiosyncrasies.   At any rate there apparently is a fix for the RX330, so it's a real problem that Toyota is aware of.
#2005 of 4686 Need.... by wwest Nov 16, 2004 (7:41 am)
to concentrate on the differences, hesitation or not.   FWD vs AWD..   I4 vs V6...   For those of you experiencing hesitation, COLD engine/transmission? Replies to this message: wil (Nov 16, 2004 9:50 am)

Replying to: wwest (Nov 16, 2004 7:41 am) My 2005 FWD V6 has the dreaded hesitation as well. I can reproduce it by slowing to 10-20mph then accelerating. Test drove another 05 FWD V6 at the dealer and it does it too. Doesn't get too cold where I live, but engine/trans temp doesnt seem to matter. Tried different grades of gas and doesn't seem to matter either. However is worse if coasting downhill at slow speed, and seems to be related to engine/trans load or lack of. I also found the hesitation is worse the quicker i depress the accelerator...at first I thought it was stalling, but then realized it was hesitation.   I swear it feels like it's either in neutral or some high gear like 3rd or 4th when it happens, the engine rpm's spin up from about 1000 to nearly 2000 before the trans engages abruptly. The hesitation occurs in that 1000 to 2000 rpm range where I think the computer brain is trying to figure out what to do then it finally finds the lower gear and goes. I wonder what will make Toyota fix this, at least for the models affected. Will it take a few injury lawsuits or a class action lawsuit? It is a very real and dangerous problem.
#2007 of 4686 File a complaint... by bobgordon Nov 16, 2004 (10:33 am)
I don't want to loose this thread. There are too many of us having this problem to let it go and we are getting new members everyday that might not be aware.   So file a complaint if you are experiencing the hesitation problem with the '04 Highlander here; http://www-odi.nhtsa.dot.gov/ivoq/   Click on "secure submissions" and fill out the simple form. When you get towards the end of filling out the form, you'll be asked the component. Click/highlight "POWER TRAIN:AUTOMATIC TRANSMISSION." Some have posted under "VEHICLE SPEED CONTROL:ACCELERATOR PEDAL" so file where you want.   Thanks   BTW, you can review all submissions on this topic by also clicking on the above link and selecting "search" under Complaints then "vehicle" under "type" then year, make, model, component, etc....
