Toyota Sienna Maintenance and Repair (2003 earlier)

    This also happened to our 00 Sienna. I can't post the links here, but do a google search for "sienna hatch broken", and a number of sites will come up with detailed instructions. Replacing the latch was easy, and only cost about $70.

    We have encountered a similar problem with our 2000 Sienna. Bought van used at 45K miles and really liked it for first three years. At 85K miles, lost AC and had to have evaporator replaced ($$$). Then at 88K miles, started hearing front-end noise when car was in motion. Had already replaced wheel bearings on both right and left front due to previous noise problems, and dealership now says we need a transmission rebuild (est $3,300 - $3,500). I never expected this after having no problems with my '93 Camry or my '88 Camry before that. Dealership called this morning and suggested we try Toyota Customer Care for post warranty assistance. Anyone had success with that route? :confuse:

    We were told that there was an offer to fix it up to 100K now and 8 years. It is under the years, but I don't know your current mileage.

    They paid for all the parts on mine, so it "only" cost about $1000. :/

    The wheel stuff I replaced came out of my own pocket. That was another $1500 or so.

    I recently took my 2000 xle to the dealer to have the a/c checked out because it's not cooling. They couldn't find anything wrong and recharged (added freon or whatever they use these days) the a/c and added some dye to check for leaks. So far, it's working fine, but the dealer is saying that unless they find a leak or a problem with something, I'll have to pay $189 for a/c service, even though I have the extended warranty (6 yr/100k). I have 70K on the van, and wondering if anyone has had a similar experience. Is it normal for the a/c to need recharged after a period of time , or would this only happen due to a leak?
    Thanks for any feedback.

    I believe you need to recharge the system every so often, even if it is working correctly. A leak will make it "go bad" quicker, but I think "normal use" also requires replacement occassionally.

    I dont agree. Its a completely sealed unit. there shouldnt be any leaks. My older 96 avalon blows cold air!

    I posted earlier, my 2001 is now on its 3rd A/C condenser. The first two got holes in them. Very disturbing! Once there is a hole, it can't be fixed because it's such a high pressure system, and you need a new condenser. I think the most recent one is a manufacturer defect, so I am going to try to get some $$ back, I'm sure it's an uphill battle with Radiators Express.

    Maybe, but the "recharge" business would be a lot less if that was always true. :)

    It shouldn't leak that quickly, but nothing in life is "completely airtight." :)

  • mathews99mathews99 Posts: 2
    We followed a similar path with our 2000 xle. When a/c first stopped cooling, mechanic could not find any leaks, so they recharged freon. W/in 3 mos, we were back in the shop for another recharge. They ran dye test but again found no leaks. Suspected problem was evaporator. Finally had evaporator replaced earlier this month, and a/c working fine again. They probably won't check that since it is labor intensive. Good luck.

    I recently had four new tires replaced for my Sienna LE 2000 by NTB tire company a year a ago. Approximately two weeks later steering wheel started to shaking at 5-15 ml/hr. I returned to NTB and complained about the problem. They rechecked it. They told me there were no problems found with my tires. After I had two tire rotations (approx 10,000 miles), I returned to NTB and complained again, but I got same answer. They told me one of my tire rims was bended. So I went to a junk yard to get a used rim and went back NTB. I told them my shaking wheel was not a mechanical problem, but a problem tire coursing steering wheel is shakes.
    It wasn't rim instead they found two bad tires and replaced them. Now I am satisfied because I don't have any problems and the new tire are covered by warranty. :)

    I have 2000 Toyota Sienna Van. I have been using the seat belts to secure car seats in the middle bench seat. My van did not come equipped with the "LATCH" system. I was wondering, can I just switch out my seat with another seat from a later model Sienna with that is "LATCH" equipped? What is the latest model seat that will fit into a 2000 Sienna. I went to my dealer, and he told me that I could fit up to a 2002 seat into my Sienna, but none of them came equipped with the "LATCH" system until 2004. I think he is wrong. According to the Automotive Coalition for Traffic Safety (ACTS), Toyota started putting the "LATCH" restraint system in 2001 Siennas. To put it in a nut shell, is there a middle bench seat that will fit into a 2000 Sienna that is "LATCH" equipped? Any help would be greatly appreciated.
  • Just got a 2001 Sienna CE with low mileage thru a dealer, supposedly Toyota certified. Driver side window scratched the very 1st time we used the window (within a week). Dealer replaced the glass. Now, passenger side getting EXACT same type of scratch, same place, same width. Have seen this reported on this board in earlier postings. Any resolution to this ? It has to be mechanical. Once I'm out of warranty I'll be stuck with scratched glass. Dealer doesnt seem to know (?) Does Toyota support any fix on this? Thanks

    At least you got a window. My driver window got it during my 36,000 warranty and they blamed sand. They supposedly blew it out. But I never got a replacement glass even though I stated I thought I needed one, and did not believe sand did it. Every Sienna that year has this scratch. This single issue is making me rethink purchasing another Toyota product by the way. Since the Service guy made it sound like he never seen this problem before. We all know he has.

    I never had a problem with the passenger side. Although my window motor on the passenger side is dead. I have a feeling all of the Siennas have that problem by the way. I also think the problem is from a piece of metal that is in the door jam. I read that they bend it so it does'nt cause the problem.

    Be aware that my front windshield also has scratches that were not caused by me. I have never run bad wipers. Yet my front windshield has deep scratches. I think its because they never properly tempered the glass. Since I've seen this same problem on every sienna that model year I know its of no fault of mine.

    You could have had those scratches since you owned the van. They could have used something to hide it from you.

    All in all the van has been fine. With exception of the wiper motor and the glass. If your van has low mileage think of using syntetic oil like mobil 1.

    Heres a thought. If they have some siennas on the lot that are used that year go look at the window. You want to bet they have those scratches?

    I have a 98 Sienna and the AC shuts off when I turn on the headlights. It works pefectly as long as the headlights are off. Has anyone had a similar problem?
  • HI everybody I have a Toyota Sienna 2000 CE, AC works great but I live in Imperial Valley, CA, temperature goes up to 120 in summer. AC works great and it is very cold,but suddenly the compressor goes off, AC switch remain on and blower works perfect but of course air is hot, after 2 minutes or so compressor turn on again. Does anybody knows what happens? or any ideas??

    I have recently encountered 2 dashboard problems. The clock is no longer working and I believe it is a fuse problem. Question is, which fuse? I'd really like to replace it myself, but I don't know where to start. Seems like there are a lot of fuses. Second problem is with my top cigarette lighter. An i-pod charger piece is lodged inside it and I don't know how to remove it. Is there an easy fix or do I need to take this to the mechanic?

    I've got a 1999 Toyota Sienna CE, just got the following 3 codes P0125 - closed loop fuel control insufficient coolant temp, P0135 - 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) & P0155 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1).

    This minivan has been at the dealers and multiple mechanics to try to repair. These are the latest readings. The dealer said both 02 sensors were bad & I had them both replaced. A local mechanic was originally getting Solenoid Sensor Malfunction, which I replaced. Then the shift cable was replaced. Can anyone help?

    Originally, when driving for a while up step hill, the car would suddenly lose power and overheat (the transmission?) After replacing both 02 sensors, out of the blue it acts as if it has no power then lurches into power - never no when and not regular. Any assistance is appreciated - you can email at as well as resply - thanks.

    the solenoid sensor sounds like it was fixed. shift cable too - i guess both needed to be replaced.

    anyway, now one of your problems sounds like perhaps a bad engine temp sensor (which might result in the unit running richer than necessary and also possibly retarding the transmission control module from shifting through all the gears).

    but, latest codes seem to suggest you've still got O2 sensor issues (I presume right after replacement). perhaps something wasn't replaced or re-connected properly.

    if your O2 sensors are still reporting bad, and if the car is loosing power going up hill, sounds to me that you might not be scheduling the correct amount of fuel to the engine, and in addition, based on them being a problem in the past, perhaps (emphasis) the Catalytic Convertor may be history soon.

    you may need to have it diagnosed by a specialist on Toyotas (maybe an independant shop - perhaps someplace other than the dealership if their work is in question).

    if you do, ask if the people that look it over again can determine if you actually got 2 new O2 sensors and if they are hooked up properly.

    question, if the dealership just replaced 02 sensors and you're getting 02 related OBDII codes, why isn't the dealership taking care of you to re-diagnose and replace parts for free?

    perhaps I'm misunderstanding your post.

    this is to protect the compressor fom over heating. If the refrigerant is low and the A/C is working not stop the compressor will cut off so it can take a breather. this is how its designed!
  • user777user777 Posts: 3,341
    and also, i believe refrigerant and lubricant must be in the system for lubrication / sealing of the bearings, otherwise the unit would surely fail.
