    Thanks to all fellow highlander owners for the informative postings which were very influential in making my decision to purchase our silver limited 6 cyl 4wd. After 2100 miles I have only one complaint - city mileage. We live in a residential neighbor hood in San Francisco with few hills but lots of stop. We have been getting between 14 and 15 mpg in town. Just curious to know how others are doing in this regard and if anyone has any suggestions.

    robsfhl - My V6 @wd is getting 18-19.2 MPG in the city and I have under 1500 miles on it

    We live in the Santa Clara area, and we've been getting 17.4 MPG with a little over 2k miles on the car.

    Thanks to spali1 and awchan13 for your responses. Still trying to figure out what I can do to get better mileage. I have been used 87 and 89 octane gas with no difference. I wonder if premium would make any difference.
  • I'm in the Miami, FL area (heavy traffic) and I'm at 2200+ miles and still getting an average of 16-17 mpg. I was using regular and switched to premium the last two tanks, with no difference in performance, just more $ per tank (LOL). By the way: 2WD V6.

    I just purchased a limited toyota highlander and like it alot except for one thing; there is an annoying click from around the top of my rear doors near the roof. When it is bad, I can get three to four clicks in a period of about twenty seconds. Fortunately, they usually go away after a minute or two. These things are pretty loud and quite annoying. Anybody got this problem? Sounds funny but it's true.

    Srbo, I've got a slight and randomly occurring click coming from the back also. With the help of my brother-in-law, he was able to narrow it down to the rear wing. A slight push up or down on it to simulate a strong wind or air flow generates a minor clicking sound, almost like the two or three plastic inserts in the cargo area might be rattling (our first suspicion). Don't know if this IS the same noise you're speaking about but it IS the source of our "clickity-clack". I'm adding this to the list for the dealer to fix. Good luck. BTW, our HL is a V6 2wd Limited.

    Really....No difference in performance when going up to premium???? Maybe it's a difference in formulas between you there and me here, but I had been reading all the discussion on pros and cons of u/g to premium, so I "fed" our V6 2WD HL with a tank of premium and DEFINITELY sensed an improvement in performance. OK, OK, so it didn't magically turn into a Ferrari or anything, but it did seem peppier. Gas mileage held about the same.

    So I did some quick math. Making the assumptions that we would put 16,000 miles per year, ONLY get 16 mpg average (very conservative assumptions) and that the difference in $ between the regular 87 octane and premium 92 octane would remain at 20 cents or less per gallon, then we would be spending $200 more per year for the premium. That's less that $4.00 per week. For me, I enjoy the "pep" and am willing to try this test a little longer to make sure that what I THINK I feel is indeed reality. Just my "20 cents" worth.

    Don't waste your dough on premium gas, it doesnt matter

    The owner's manual says you are supposed to be able to remove the radio antenna by turning it counterclockwise. I can't budge the thing! This is a problem as I'd like to take it to a car wash. Anyone had a similar experience, and any ideas?

  • gwkisergwkiser Posts: 326
    Srbo (and others), I was able to remove the rear wing and used a silicon based lubricant (NOT CEMENT) around all the rubber gaskets/washers and then reinstalled the wing. Bingo! No more rear noise. Hope this helps. Oh, btw, access to 3 mounting bolts is easy....just remove the 3 round rubber grommets on the underside of the gate near the hinge areas. You'll have to persuade (very carefully) the 4th mount upward on the left side. It's a tapered snap-in plasic plug and receptical. Don't forget to lubricate both halves of this also.

    I don't know about removing the antenna, but the car wash shouldn't hurt it. Most nowadays are touch-free, anyway. Usually I scrub my HL by hand, but there was no damage of any kind when I put it through an auto-wash. Except for dried soap streaks. : )

    We have a Silver 4 Cyl Highlander all wheel drive, with rear spoiler, floor and cargo mats, console, color matched mud guards, roof rack and preferred package, keyless entry, etc, purchased in Pasco, WA for a flat $25k. Window was $27,376.00.

    So far so good, but the roof rack for us is purely ornamental. Does anyone know how remove the cross bars on the roof rack?

    The Dealer we bought it from said they would "try" but I chose not to take that chance. They were installed at the factory, but there has to be way to remove them. We would like to remove them to reduce the wind noise.

    Our mileage is about 21 all around driving. Have not gone on an extended trip yet. Have not had any problems. We love the vehicle.

    yes I have also found that there is definetly an increase in performance when you use premium gas. Since I don't pay for my own gas, I have no problem using premium :)

    We have been experiencing problems with the AT release button (the button you press with your thumb to engage the automatic transmission). It occasionally has been locking up so that a great amount of pressure is needed to depress it. We brought it in to the dealer and it of course worked perfectly. The technician pushed it in about 50 times in row with no problem and said he couldn't find anything wrong. He told us that if the problem happens again to bring it back and that we would have to leave it in the shop for two days. Has anybody else had this problem or have an idea as to what could be causing this?

    I've noticed a clicking also, but it seems to be coming from the sunroof. It happens a lot with it tilted or closed. If I push on the sunroof, I can sometimes recreate the noise. Anybody have the same problem? Almost sounds like springs or wires snapping.

    I must say, premium gas is the way to go. Just this past weekend I drove from Sacramento to L.A. and made about 305 miles on a full tank of gas. But when I switch over to premium and the mileage increased to 340 miles on a full tank. That is impressive. Even during city driving there has been a significant increase. Performance....what can I say? Excellent!

    On June 1st, we bought a 2001 Toyota Highlander Limited from Bernardi Toyota, Framingham, MA. Had the best experience with a car dealership that we have ever had. We got a wonderful deal on a great vehicle.

    I really have only one complaint at this point and hope someone has an answer before I have to visit the dealership. We are getting a plastic sounding clicking noise which seems to eminate from the passenger side, back seat area. At first I thought it was the sunroof because the first time I heard it was when I had the sunroof open for the first time. Then I thought it might be the seatbelts, but I've played with those and can't get the noise to occur when I'm fooling around. Help/suggestions would be greatly appreciated before I head to the dealership.

    Secondly, I am looking for a site for aftermarket conoles that will fit the Highlander. I am not interested in the Toyota one as it makes no sense to me to have to keep the lid open when I'm using the cupholders.
