Toyota Highlander Maintenance and Repair



  • We have not replaced the battery, but sounds like a good idea. Should we just outright replace without any check of it? Some people have suggested a few interesting things. One was the weight of the key ring and the other was whether we have another vehicle key on the same ring with a chip in it...Does anyone think the battery could cause the total failure? Toyota said there was some $800+ code or something they are trying to avoid going to.

    Borrow a battery from another car..?

    Totally new batteries can be just as suspect as old batteries, manufacturing defect gone unnoticed.

    I would just out right replace the old battery with a new one, but don't get the same brand. Get a good quality brand from your local Autozone or Advanced Discount store, stay away from Wally Mart.

    Interesting thought on the key ring, just try a different key that is not on any key ring, not likely, but I know how frustrating a flaky electrical issue can be, and you're probably willing to try anything.

    My dad had a Caddy with similar electrical flakiness, dealer replaced a ton of parts charging him big bucks. His next door neighbor changed the battery cables. When he cut the old ones right down the middle, they were corroding from the inside out.
  • I cannot agree about buying a non OEM battery. My 03 Highlander lasted 6 years before I had to replace it.

    You can't get that kind of life out of a battery from anywhere!!

    My guess is that there are no more than 2-3 car battery manufacturers today, just sold under various labels.

    But I would NEVER go to a car dealer, same battery, higher price.

    Unfortunately we can't get the same original batteries that were put in the HL in Japan (Panasonic, at least in my 2001). Batteries sold by Toyota dealers are not the same.
    Check Consumer Reports for their latest tests, and get one with a long warranty which can be honored at many places, like the chain auto stores mentioned, or Sears.
    That said, I replaced mine with an Interstate from a friendly local gas station. Probably paid a little more, but the guy does me favors in other ways since I go there all the time.
  • i broke a plastic small hose connection on the side of the air filter cover when replacing the air filter on a 2006 Toyota Highlander V6 3.3. what is this hose for and is the car driveable in this condition?
  • I'm not 100% sure but believe that hose on the air filter housing is a part of the emission control system. If the vehicle is driven with this hose disconnected, the Check Engine Light will illuminate. You either need a new cover (try your local junk yard or e-bay ) or try to glue plastic nozzle back with good epoxy, make sure to keep it open inside!
  • I took a long trip last weekend. An hour or two into the trip I realized the A/C wasn't really working. The blower wasn't blowing air regardless of the speed it was on. There was a bit of cold coming from the blowers but not significant air flow. I turned it off for 30 minutes, turned it back on and it worked fine. Few hours later the problem happened again. This problem didn't seem to happen during the hottest hours of the day, mostly just morning and evening.

    Left it with a repair place, they cleaned the drain. That didn't fix the problem. Left it with my normal mechanic when I got home, they couldn't recreate the problem so couldn't figure out what was wrong.

    Any ideas? Low freon? Leak somewhere???

    Toyota A/C system seems unusually susceptable to evaporator freeze up going over mountain passes, SOP.

    If otherwise see an A/C technician.

    This is most likely broken/intermittent wiring connection to the AC/Heating controls. Pretty common problem for 1st gen HLs. About $900 to repair at the dealer or simple and free DIY fix. Google "highlander ac controls broken wiring"

  • I just had this service done on my Highlander 03 w/65K miles. I consider it pretty reasonable IF they check everything.

    I'd rather not be hit with surprises later.
  • I always take it to the dealer for oil changes/rotations and thought if they seen something wrong they would let me know about it. It says they do multi point inspections and then they give me that paper which shows everything is ok. So I figure why spend another few hundred for a 60k package.....that's where I was confused. I know they change the fluids and stuff, but I didn't want to pay them to "inspect" things when they already did it at the oil changes.
  • 2003 HL limited clicking sound coming from under the dash It's not a rattle because i hear it sitting still.... I know where it's coming from its in the center of the plastic air chamber. I thought it might have something to do with the climate control but everything seems to be working ok.
    I can see the control devise thats clicking and I can put my finger near it and feel the motion at the same time it clicks. I turned off the air and it still does it.

    any Ideas would be appreciated.
  • Turn the radio on! that's what the dealer told me years ago when I heard a ticking noise just on the other side of the firewall from where you are hearing your click. They replaced the fuel rail, said it was coming from that, since they couldn't fix it, they said turn the radio on. The noise is still there, but it doesn't bother me when the radio is on.
  • One year later, I want to add to the above about using Goodyear only for tires. One year later, my brakes and rotors are still fine yet Goodyear would have had me replace them. Even though I no longer let them do any work other than tires for me, I am still finding things they did where they ran the cost up. The latest one is that I asked the dealership recently to put new wiper blades on. They told me that I no longer had their brand of WIPERS on the car and so they didn't have blades to fit. I remembered that I had asked Goodyear to change the blades and I had questioned their high cost when paying. I didn't realize that since Goodyear didn't have blades to fit, they didn't tell me that so they changed the whole wipers! I went back and looked at the worksheet from Goodyear and I had signed their pre-work sheet asking for wiper blades; below it they had charged me for wipers.
    All of this to say that my experience with Goodyear for maintenance has ranged from outright lies to lies of omission. As long as I've kept my maintenance records on the tire rotation, I've been able to make them live up to their warranty although they really tried not to. Beware of using them for general maintenance.
  • I stopped doing business with Goodyear a long time ago. I bought their lousy tires at a dealer and I am done with tires as well. Tires that are supposed to get 60K get 18K on a jeep and 28K :lemon: on a Highlander, Look at BF Goodrich and General for your tires. You'll be happy and will save money And if you've have lost your receipt at Goodyear you are out of luck. They just suck
  • Thanks steves8--I play my radio pretty low since wife is usually with me.

    So I still hear it--since everything is working I've decided to wait..I did notice when my car is sitting out in the sun and it's very Hot inside i turned the air down to 70 and there's no clicking until I set the temp back to 75.

    Thats why i think it has to do with climate control--like trying to keep temp to setting.
  • Occassionly on our 2002 AWD Highlander when we put it in reverse the vehicle hesitates and then jumps back and there is a "cluncking" noise in the transmission/transfer case area.

    Anyone else had this intermittant problem??

  • Hey owners of 2002 Highlanders that haven’t been recalled. Does it have drive-by-wire electronics? Is the pedal top-hinged such that floor mats can catch the pedal as in others?

    Be careful – see ota_in_fatal_crash/
  • My Highlander's trans works great for 30 minutes then it will not up shift to over drive (OD). AAmco wants to take it apart and diagnose. It's a 2001 with 140,000 on it.
  • wwestwwest Posts: 10,706
    At 140,000 miles the engine may not be producing enough torque at the low RPM used in OD lockup.

    Drive by wire started with 2004 Highlanders.

    My question has to do with the moonroof. Last time I brought the car to the dealer with the complaint that the moonroof leaks I was told that the car has a "drip tray", so not to worry. Is this true or is the dealer making this up? Does the car truly have a drip tray when the moonroof leaks? I can't tell if there is such a thing when I was trying feel to the tray. Or, are they just lazy and don't want to fix the seal around the moonroof? They did a test when they hosed the car down and saw that some water came through, that's when they told me about the drip tray. I am just trying to get to the bottom of this.

    Many thanks,

    "the moonroof leaks "
    "They did a test when they hosed the car down and saw that some water came through"

    And they said not to worry about it? If so, of course that's nonsense. Most sunroofs have drains which go down the A-pillars (next to the windshield) to drain water that gets past the seal (and probably into this "tray" thing). The drains get clogged with debris, and need to be flushed/blown/rodded out.

    Any dealership that does not know that doesn't deserve your business. Take it somewhere else - it's not a Highlander-specific or Toyota-specific, so find a highly rated repair shop. Or get your neighborhood gearhead to do it for you. It's far from rocket science.
  • i have a 2002 hl and both rear windows are now broken. were you able to find out how to take the panel off? thanks, rr70
  • Correct....Found the cabin sensor plug and hose disconnected. Left that way by the Best Buy installation staff!!!
  • Hello all,

    I have a few questions related to the maintenance of my 2006 Highlander. I have a 2006, 4 cyl, with the 2AZ-FE engine. I have ~80K miles at present and I don't see anything in the maintenance schedule about timing chain and transmission fluid replacement. I see that the 6 cyl requires a timing belt replacement at 90K, but the maintenance guide is silent on the chain for the 4 cyl. When will the chain need to be replaced? With regard to the ATF, it only mentions replacement at 60K and 120K miles for towing. When should the ATF be replaced under normal operating conditions (ie no towing)?
