You are in the Toyota Highlander
What is this discussion about?
Toyota Highlander, SUV
#3962 of 5330 2003 and 2005

In 2003, we bought a new 2003 Highlander V6 2WD and loved it so much, in mid 2005 we added a 2005 limited V6 2WD to the family. They have both been excellent vehicles, the 3.3L V6 and the 5 speed automatic in the '05 feel more powerful than the 3.0L 4spd automatic on the '03, and the '05 also gets better fuel mileage. They have both been virtualy perfect driving vehicles, with only 1 or 2 minor warranty issues combined. Quite possibly, 2 of the best vehicles we have ever owned, and I have owned over 45 vehicles in my 55 years.
Before buying the 05, we read with great interest on these same forums, about hesitation issues that a repeated few were reporting. We test drove many, many examples of Toyota corp vehicles with this engine/trans combo, and never did experience the dreaded hestiation, so we bought it. I will say, that for a while, I half expected it to raise it's head, but.....It has been almost exactly 2 years, and about 30,000 miles of perfect performance.
When the Camry Hybrid came out in June 06, I just had to have one, and we decided it made sense to replace the "older" of the Highlanders with a more fuel efficient vehicle, so we traded the 03 HL on the 07 Camry Hybrid.
It does make more sense to have one utility vehicle, and one "economy" vehicle, (rather than 2 SUVs) altho, had it not been for the Camry Hybrid, I would probably made a new personal record for the time owned on a single vehicle with the 03... I suspect that the '05 will now take that title, as we love it, and have absolutely no reason to even consider it's replacement in the forseeable future.
To stay more or less on topic, on the '05, we change the oil at 5,000 mile intervals, rotate the tires (5) at 7,500 miles, and I just changed the air filter. Other than that, i don't think the 05 has been to the dealer for a single warranty issue...and I am VERY picky... and sensitive to sounds, rattles, hesitations, surges, vibrations, etc.
Sorry for long post.

Don't be sorry for the long post. Lots of encouraging stuff for us potential Highlander buyers. I keep reading about the "hesitation" issues. However, I have test driven at least half a dozen Highlanders and cannot identify this as a problem. Nor can I get that issue from any current Highlander owners in my area.
I am not saying that it doesn't exist, I can only say that it is not in my actual experience either test driving or discussing the issue with Highlander owners.

Remember, people with problems tend to post on these boards. Owners with no problems don't. The vast silent majority is out here. You are making the right decision. Just test drive the actual car you are buying and don't take it off the lot until it is to your satisfaction.

The observation that "Whingers post, happy folk keep their mouths shut" seems apt. That said, I had some minor issues with the shift points for the trasnmission in my 2005 Klugerr (Highlander). Problem was largely fixed by a Flash of the ECU to amend trasnmission shift points. However, shifting can be a bit rough as a consequence of driving patterns. The transmission control is adaptive and responds to recent driving patterns. When the problem has cropped up, I have found that very rapid acceleration / deceleration through three cycles solves any transmission shift issues.
Now having mentioned this, I responded to one poster explaining the remedy and that it was a consequence of his recent driving pattern. His immediate response was to interpret it as confirmation of his view that the vehicle was defective. Reminds me of onw mechanic who assured me that the one part he could not fix was the nut behind the wheel!
#3966 of 5330 adaptive?
Mar 20, 2007 (3:33 am)
where is there any written mention of a transmission being adaptive?
I think thats an urban myth
How does thst work in a rental car fleet?

The way it works....
All individual driver "learned" techniques, traits, driving styles, are ERASED each and EVERY time you shut the engine off.
The system starts learning driver adaptive techniques as soon as you start the vehicle in motion, within a fairly short time it will have you "sorted" into one of four categories and within ~4 minutes you will be refined into one of sixteen categories. Thereafer it keeps only a three minute history upon which to "bin" your driving style. So it will (re)learn as you go, change your driving style on the go, it will adapt.

Finally something that makes sense. I kept seeing all these posts noting that the Highlander adapted to only the "primary" driver. Not to any driver withing a few minutes.
Hence it was beginning to seem that a Highlander would only operate at its best performance when the "Primary" Driver was operating it.

The reason the dealers service personel are confused is becuase there are two types of adaptive "learning" involved. For instance prior to DBW the engine ECU had to "learn" the proper control voltage for the idle air bypass control solenoid. Of course it would then remember that indefinitely as long as it had battery power.
There are literally dozens of engine and transaxle operational parameters like that it must learn and remember indefinitely.
But not unique driver parameters.
#3970 of 5330 Just wait.
Mar 26, 2007 (6:39 am)
All I have to say is just wait until your Highlanders have more miles on them. Thats when the trouble begins. I have a 2004 with over 50,000 and more and more issues keep coming up. I know I am not alone. Ask any auto repair shop about the issues that Toyota is experiencing. If a mechanic won't buy one, that says something!

I'm already past that, still no problems. Maybe you need a new mechanic.
