Toyota Sequoia Maintenance and Repair



  • I am having a similar issue with the VSC coming on in corners on dry road. What was the issue? My dealership cant figure it out.
  • cabin04cabin04 Posts: 31
    My VSC problem is pointing towards a bad computer component that controls the engine, excelorator, and brakes that help prevents the skid.
    I can't do anything with this VSC problem until something is done with my rotted frame, which is currently more critical. I'm hoping that my VSC problem is really a bad sensor, and not the computer. My VSC problem only occurs when I have passengers in the 2nd or 3rd row seats.
  • I am going to have to take a look at my frame! I always have people in my 2nd and 3rd row. I have 5 kids. I find that mine goes off more on left hand curves. The last time I drove it the VSC came on and stayed on until I had slowed to about 2 miles an hour. I lost control of the steering and it pulled me off the road. The dealer keeps sending me home with it.

    Yes, take a look at your frame. Please send me an email, and I'll send you some pictures of my frame for comparison.
    The Toyota dealership should be able to read the codes which should point to the cause of the VSC going off. It's either a bad sensor or the computer that controls the VSC.
    When the VSC, skid indicator, and audio alarm all go off, indicating a skid, and the computer takes over and controls the engine and brakes, the only way I can get it to stop is to stop the Sequoia, turn off the egnition and turn the vehicle back on again. The vehicle will run okay until you go around another curve in the road.
    Has anyone else out there experienced their Sequoia thinking it's in a skid when it's not??

    Is this rust endemic to all geographic locations or only to places that use salt heavily in the winter to clear off the roads?

    In Texas, we use sand, not salt for road clearance and rust generally is not a problem. Also, I have lived in cold weather country (Northern Virginia). We just took the vehicles to the car wash, which had an under-carriage rinse facility...usually about once a month was all it took. No problems and this was mid-1980s before improved rust proofing.
  • For what I understand, the Sequoias are built with the same frames as the Tacomas and Tundras which were recalled because of a defect on the frames that is described as "Premature Rusting." This rusting is caused either because of substandard material and/or because of manufacturer's storage of the units. The frames are rusting from the inside out. Toyota settled a lawsuit with the manufacturer of the frames for $25M.
    Most of the affected vehicles are from northern states where winter is most prevalent and many states uses a mix of sand and salt to treat roads, a practice that have been going on for over 40 years. Manufacturers knows of this practice and install the frames with anti-corrosion coating. Somehow Toyota overlooked this condition and put these defected frames on the affected vehicles. I have read post of other states having the same problem but not as extensive as Snowy states. Other makes of vehicles are not experiencing the same rate of deterioration as the Toyota Sequoias, Tundras and Tacomas. Salt is not affecting all the vehicles the same. There are vehicles on the road with 15, 20 years and longer where their frames are still solid with just minor surface rust even though these vehicles are in the same states that uses salt. This salt issue is the argument Toyota and their defenders want to use to deny any responsibility. They already accepted and recognized that the Tundras and Tacomas had "prematurely rusting" frames. The Sequoias should be at least considered for a more in depth look at the condition of frames and determine is not all but some of the vehicles were built with this defective frame.
  • So my wife and I just bought 2001 Sequoia with 158,000 miles on it but we weren't worried because of the Toyota name and quality. We have had a 1996 Camry and a 2000 4 Runner with almost zero issues. We currently have a 2007 Camry and now this Sequoia.

    After reading some posts on here I went out and looked at the frame under the engine compartment and noticed 2 small rust holes the size of a dime each. Other than that though my frame doesn't even show signs of rust. We live in Michigan, so it see's its fair share of salt. Before we bought it I brought it to my friends garage and he put it on the life and everything, frame looked good on the bottom. Should I be concerned with only 2 small spots?

    On December 28, 2011, I brought my 2001, Toyota Sequoia in to be serviced for rear brakes and to get the oil changed. My certified mechanic called me at home and strongly suggested that I come in to see what he discovered while my vehicle was up on the lift. So I stopped in to take a look. He showed me extensive rust holes in the middle of the frame welds on both the passenger and driver's side. He also pointed out that the rear differential case has severe rust damage. He strongly urged me to stop driving the vehicle and stated that it is unsafe in its present condition and that he has never seen such extensive frame rust damage on a vehicle this well taken care of. The drive train, outer body, and interior are in mint condition. I also have always made it a point to power wash the salt (calcium chloride) off the under carriage after driving in the Northeast after snow or ice storms, when salt is used on our roads. I contacted my local Toyota dealership and they gave me the phone number to Toyota Headquarters. The end result was, they were sorry to hear that I had a rotted out frame and suggested that I get rid of the vehicle because there is currently no recall for the Sequoias. Although, after going online at the Toyota forum I found out that they're are over 300 consumers with the same type of issue with their Sequoia frames in our state, so I do not stand alone. I am floored that a company like Toyota, that prides itself in being committed to safety does not care and will not take ownership when they knowingly used cheap Japanese steel to build these faulty frames. I currently have three young children and this is my primary vehicle. I cannot afford to throw $8 K away (Kelly Blue Book) on this vehicle. Please help!
  • Sorry to hear that. As you can see there are hundreds if not thousands of vehicles in the same condition including mine. I don't know what would take for the NHTSA to start investigating this issue. Perhaps a death or a whole family mainmed. At this point I think our government is failing us. NHTSA if you are reading these posts please help us. Toyota Motor Sales USA will not do anything until our government steps in. They will tell you they are sorry your vehicle needs repair and that it is over the warranty period. They will tell you that they have never hear about this problem with the Sequoias. They will say not to believe anything thing you read online. All lies meant to discourage you from seeking relief. Have a Toyota Dealership conduct a frame inspection and get the results in writing.
    File your complaint with the NHTSA and with your state AG. Be prepare to hire a lawyer to represent you in court. Take pictures of your vehicle to show the condition of your car as a whole and the frame rust. could also help by forwarding threads like this to the proper authorities if is interested in addressing some of the safety issues we are all experiencing. What about this Edmunds? are you willing to help us?

    Sorry to hear that you have joined our group of unhappy Sequoia owners.
    For whatever it's worth, file formal online consumer complaints with the NHTSA and your State Attorney General's Office. I am extremely disappointed in the lack of support from both our Federal and State governments. I've had a couple conversations with the NHTSA and they have no plans to even start an investigation regarding this serious Toyota Frame Rot problem, even though they have a database full of complaints. And my State AG's Office says they have NO authority to even get Toyota to respond to my case. Therefore, what's the purpose of these agencies.
    Media coverage of this serious problem will probably be the only way to get Toyota to do the right thing and/or a class action lawsuit. Taking legal action on your own against Toyota won't get you enough money to even pay your lawyer.
    We should all be fighting for a "buyback" option and not just a frame replacement.
    From what I've heard from Toyota Tundra owners who had their frames replaced, had nothing but problems afterwards. And many ended up just getting rid of the truck to stop the headaches.
  • I just had my 2001 frame replaced by Toyota without any cost to me. They told me if there were any additional parts that needed to be replaced while they did the frame we would have to pay for that, but not the labor since they were already doing the frame. I had it done at Premier Toyota of Newport (Rhode Island). The service manager, Ray, said that he would do whatever he could do to help other Sequoia owners as long as the regular maintenance on the Sequoia had been done at a Toyota dealer (which is shown in their nationwide data base). Another 2002 Sequoia's frame was being done when I picked mine up. Hope this helps!

  • Hi somrtym, you had posted back in December 7 that Toyota did or was going to replace your frame. I assumed by your new post that the frame was finished recently. Someone else had asked what process your put in place to have them so easily agreed to replaced the frame. I just got noticed last week that Toyota had responded to the Consumer Office referred to by the Attorney General in my area. Toyota response was just sending them the same letter of claim denial they sent me. A copy of it.
    I will try to contact Toyota again to see if they have a change of heart. It seems that there is no recourse unless individuals are willing to take it a step further. The NTHSA and the AG are of no help although they know the problem exist and is real. Please let us know how you got to convince them to do the right thing.
  • Hi...I also just took my 2001 Sequoia in for an oil change and they advised that is was unsafe to drive. They had a Toyota FTS come out and do a report, I filed a claim with Toyota and with teh NHTSA. However, the Toyota Customer experience representative said they could offer me nothing in return. I purchased the vehicle in Kansas City but the vehicle came from PA. Can you please tell me the steps you took to getting your frame replaced? I'm willing to do most anything as the vehicle only has 97,000 miles on it and is in amazing condition except for as the service manager said it " the frame has cancer".
    Thanks for your advice, I appreciate it.
  • Sorry you are having the same problem most of us are having. Toyota will deny any claims unless the Government gets involve which is about time.
    File a complaint with the NHTSA at this site:

    Also, file a complaint with your Attorney General.

    If you read past posts there is more info there.

    Good luck.

    How did you get it replaced at no cost?

    I just took my 2001 in for an Oil Change and rear door handle and the dealer told me about a 4 inch hole in the frame due to rust and that it is unsafe to drive. Contacted Toyota and got the "There are no recalls to address this issue..." My dealer contacted Toyota directly to open a case with them. I have taken my vehicle to the same dealer for service ever since purchasing it used. It now has 255k+ miles and runs great. No major problems until today.
    I have filed a complaint with NHTSA already and hope others do as well. Hopefully Toyota will issue a recall at some point. After all, my understanding is that the Tundra is based off the same frame and there is a recall for the Tundra frame issue.
  • I asked the same question. somrtym either is just pulling our legs or just don't want to help. Maybe Toyota swear her to secrecy. File the complaint to the NHTSA and try to alert as many people you see with Sequoias. Get a lawyer!

    So I've seen a lot of others with this same problem but I too need some advice. When my alarm goes off (for no reason), I've checked and do have a dome light on inside the car, but no door adjar light on the dash. I tried removing the drivers side door switch and thought that fixed it. It didn't go off for 2 days, then went off 4 times in a row. I'm now thinking it's the rear door, because sometimes the dome light doesn't come on when opening the rear door and also get no door adjar light at least with no key turned on. When I turn the key on then I do get the door adjar from the tailgate (hmmm voltage issue)? I was hoping its only a rear tailgate door jamb switch, but I can't find one. How does the rear door adjar work on these without a visible door jamb switch? Where is the thing? Thanks

    I have a 02 Sequoia Limited with 150k miles. I wanted to know if anyone has attempted to remove the catalytic on the exhaust permanently? I live in a rural area and they don't require emissions so Im not worried about that part. I wanted to know if there was a way to trick the O2 sensors on it since there is one before the cat and one after on each side. I also wanted to do this to improve the MPG on it since I only get 14mpg and can't seem to get any more even when Im on the Freeway. Also I wanted to know if anyone has actually installed a aftermarket intake and what type of difference did you see in it. Thanks

    I just purchased a used 2002 Toyota Sequoia and the Radio Power is not coming ON when pushed. I checked radio fuse and it is OK. What else might be the problem?
  • I've read a bit about my car, so I am familiar with the ABS/TRAC self test noises that happen after initial acceleration.

    My Sequoia recently started making another noise after those clicks, it sounds like a puff of air coming from somewhere under the dash on the driver's side. This didn't start happening until after we got it back from the dealer for service on the ABS computer system.

    Any ideas what this could be? Something I can simply fix or do I need to call the dealer again?

    I have a 2003 Sequoia and am experiencing the exact same power loss symptoms. How did you fix the problem?
  • See my post #2039.
  • I have a 2001 Toyota Sequoia Limited and just replaced the belt tension. Love my vehicle and considering it has 460,000 miles on it she still runs beautifully. Anyone else have high mileage on theirs and still running great?
  • harboharbo Posts: 136
    I feel like a "piker" with only 200,000 on my 02. Runs great and feels like 200K more. Any maintenance tricks.?
  • doby2doby2 Posts: 3
    Hey I have a 2003 and we just hit 200,000 and we just love this truck. It has a smooth ride for an SUV. In fact we love it so much this is our second one we had 2000 the first one off the line out of Indianopolis toyota plant when the model was brand new. We tried a Q56 in between that one and the 2003. I say stick with Toyota we have found it to be very reliable and we have only had to do a few minor things to it, a Yaw Sensor and the dealer replaced the tracking system other than that it's been a solid truck. By the way we put almost 300,000 on the first one..
  • I had a small fire this evening under the hood of my 2003 Sequoia. The problem started when I shifted from reverse to drive and the brake pedal seemed to temporarily lock up. A mile or two down the road, the VSC/Trac Control light came on, followed by the ABS light, followed by the smell of burnt plastic, followed by the brake pedal going all the way to the floor on its own, while driving in traffic.

    I'm trying to track down a diagram of the engine compartment to determine exactly what caught on fire, but I'm assuming its the VSC computer or something else brake related. It was a box located in the far left corner of the engine compartment, right up against the fire wall.

    If someone could help identify this for me before I head to the repair shop where it was towed, that would be helpful so i can do a little research. From what I've read on here tonight, there have been plenty of issues with the VSC computer and possibly even a recall or two. Any chance this repair will be covered by Toyota? If not, and because it involved a small fire, will my insurance be able to cover the repairs or am I looking at a pretty hefty out-of-pocket expense?

    I took my 02 Sequoia SR5 in for a recall with the undercoat on the frame. Although it passed with no damage, and they applied the required undercaot protection, they found a laundry list of other items in need of attention. Just wanted to run the list by others to see if it sounds reasonable. Because the car is still at the dealership, I don;t know the exact mileage but it's about 160,000. Here's the list and applicable costs:
    oxygen sensor (high priority) - $600
    power steering fluid, dirty and leaking from both lines (high priority) - $1158
    timing belt
    induction service (clean carbon out of upper intake and throttle body) - $169
    transmission fluid cleanse - $110
    brake fluid cleanse - $130
    corroded battery cleanse - $65
    coolant flush - $80
    spark plugs - $284
    brakes @ 30% - brakes and roters - front=$606, rear=$653
    Your thoughts???
  • Take your car out of there and run as fast as you can. Take it to a competent mechanic and have a second opinion. Show them the list but not the prices. Although you may need most of all that work done you may be able to do it at half the price. Do not neglect the power steering fix and the brakes job. If the car was running fine before you took it in it should run the same now for some time, enough at least to take to another mechanic. Some shops will even let you bring the parts in like the rotors ($80.00 a pair), brake pads $40/60) Spark plugs and oxygen sensors. Check around on some auto parts stores, they some times run a computer test for free and let you know exactly which one you need, the car has four. You only will need to replace them a couple of weeks before your state inspection. If they are faulty, the damage is contagious, one bad sensor can damage the second one in the same bank, 2 sensors per bank. Good luck.

    Thank you!! I did more research online after my post and came to the same conclusion regarding cost. The only reason I went to the dealer in the first place was to have the recall item attended to, I do have a mechanic that I trust and will certainly take it to him. I appreciate the feedback!
