#4002 of 4026 Toyota lost my business today
Jan 10, 2007 (6:17 pm)
My wife and I generally keep a vehicle 5-6 years. We have grown accustomed to the usefulness of an SUV but would like better fuel mileage. Time to let the Jeep Liberty Ltd. go. We finally decided upon the Highlander Hybrid Limited with 3rd row seating and navigation. Once we finally got past the $42K sticker shock, we felt that this would be a car worth having for years to come.
Upon further investigation before departing with the $$, I find that this expensive vehicle and techno advanced vehicle was still in the dark ages. Blue Tooth technology is not available in the 2007 Highlander. However, it is offered in many of Toyota's lesser vehicles. What in the world are they thinking????? If you visit Toyota's website, they offer an extensive education on their navigation system as found in the Prius but only offer a piece of junk nav system in the Highlander as a $2,000 option. HELLO
I am still in shock and awe. I voiced my thoughts with the dealer, put my checkbook back in my pocket and left. Sorry Toyota but you lost my business.
#4003 of 4026 frustration with check engine warning light
Jan 19, 2007 (8:04 am)
I am an owner of a new 2007 Highlander Limited Hybrid, otherwise a technological wonder. I had a frustrating experience with the check engine yellow warning light that appeared on my dash. The owners' manual only said to take it to a dealer. A snow storm intervened, so it took two days to get to the dealer. They had to connect the engine to the diagnostic computer to interpret the error code. I decided to wait to see what the problem was, so after over an hour, a young woman announced that my car was ready. "What was wrong?", I said. She does not know and says I will have to talk to the service manager. So what was the big problem that gave me so much grief for two days? The gas cap was not tightened! (In Oregon we are not allowed to pump our own gas, so a gas station attendant left the gas cap loose!) The service manager explained to me that this was a federal government requirement to prevent gasoline vapors escaping into the air, adding to air pollution. He further explained that it takes the engine 12 to 14 hours to sense that the problem is corrected and to reset the warning light!
My feature that I would like to see: Have the engine's computer interpret these engine error codes and write a human understandable interpretation on one of the two displays of the Highlander. It does this for other simple problems. Why not the engine errors? And make the reset time faster.

I wish I'd had that on my Mercedes ML when it happened to me. Dealer told me the same thing. So it goes...

I'd like to make two of the suggestions a reality. Has anyone wired a switch into their car for control over the daytime running lights? I'd love to kill those sometimes.
Has anyone hooked up a trailer hitch? Any suggestion on best price? (I want mine for a bike rack as well, therefore the cheaper/lighter the better)

You can buy an OBD II Code reader for $149 on-line. This OBD II reader can be connected to all newer cars (post 1996??) to read the error code.
Our SIenna had a check-engine light ON a while back too and error code matched that of gas cap problem. So I bought a $15 gas cap to replace the old gas cap and reset the light. The light never came on again. That saved us a day at the dealership and a minimum charge of $85.

#3 is an easy DIY.
Just add a pre-processor to the front wheels' ABS sensors so that they appear to slip each time an incremental downward movement is made on the gas pedal. The hybrid system will react to the "slippage" by instantly making the rear motor the primary motive force.

The HH does not use the Atkinson cycle. My guess is that with 30% better FE, more energy extracted before the exhaust, it would not allow enough heat to reach the catalyst.
The Prius ACTUAL compression ratio is ~13:1, the EFFECTIVE ratio is only 10:1. This is done by leaving the intake valve open for a fixed period of the compression stroke, allowing a portion of the A/F mixture to be forced back into the intake manifold.
The positive effect of this is to have, effectively, a longer power stroke than the compression stroke, converting a higher percentage of the fuel "burn" into usefull motive force. On the negative side a 2.0L engine now produces only the power of a 1.4L.
Mazda made up for the difference by going one step beyond the Atkinson Cycle, to the Miller Cycle engine. Added an SC to BOOST the inlet charge and make up for that 30% power loss and still attain that ~30 improvement in FE.

To which Mazda model are you referring?

The rear electric motors are not designed for that much use. They would overheat. Toyota might be able to implement more use, by upping the motors, and modifying the master CPU, but a "DIY" would probably end up damaging the vehicle.
There is a good reason that Toyota does not recommend going "off road" - the AWD will not stand for it.
