2001 Toyota Sequoia Problems

What owners report

Owners of the 2001 Sequoia most often describe the vehicle stability control (VSC/TRAC) system engaging on its own during ordinary driving on dry pavement, sometimes with a buzzer, a grinding noise at the brakes and a sudden pull to one side. Brake vibration and shudder, and extensive frame rust on this age of truck, are the other themes that recur across the sample. Most reports arrive well past 80,000 miles, with the VSC complaints spread from about 50,000 to well over 200,000 miles.

1. 1
   Electronic stability control

   VSC/TRAC engages by itself and pulls the vehicle

   • 262 complaints (49%)
   • median 121,150 mi at 10.7 yrs old (238 state mileage)
   • 7 mention a crash, fire or injury
   • owner-quoted repair $2,000 (median of 36 quotes)
   • filed 2001–2025

   Complaints describe the VSC, TRAC and skid-control lights coming on without a skid, often with a beep, a grinding or rumbling noise at the brakes, a brief loss of power and the vehicle pulling sharply left or right on dry, straight pavement. Several owners say it first appeared intermittently in cool weather and later stayed on constantly, and that restarting the engine clears the lights for a while. Dealers reportedly diagnosed a yaw sensor, brake booster or the skid-control ECU/computer, with repair estimates commonly quoted around $2,000 and up; some owners say the computer logged no codes at first. Spread widely from about 50,000 to over 200,000 miles, reported at speeds from parking-lot pace to highway speed and on dry roads.

   What to check: Drive it on a straight dry road at highway speed and watch for any VSC/TRAC light, beep or pull; ask whether the yaw sensor, brake booster or skid-control computer has been replaced and keep a scan tool reading of stored codes.

   2 excerpts from owner complaints in NHTSA records

   “My 2001 Toyota Sequoia with 199000 miles will apply the ABS to the right front tire and then disable the vcs system. This causes the vehicle to pull to the right and has forced me off the road. I have had it looked at and the computer code was a bad yaw sensor. The mechanic verified the sensor was good as was the wiring. I'm told the vsc computer may be bad.”

   NHTSA complaint #10346267, filed 2010-07, 199,000 miles

   “Vsc / trac system engages randomly... Sometimes three times per week. Started about one month ago. Various speeds, various circumstances... Nothing consistent. It has pulled me off the road twice, but most of the time just engages with a rumble sound and hard to drive. The computer diagnostics finds nothing. I have used auto-blog and discovered dozens of people with the same problem.”

   Body and structure

   Frame and underbody rust

   • 119 complaints (22%)
   • median 144,000 mi at 11.5 yrs old (87 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $5,000 (median of 9 quotes)
   • filed 2004–2026

   Complaints describe heavy corrosion on the main frame and underbody, in some cases perforation found at inspection or a frame that a dealer considered unable to support the vehicle. Owners also mention rusted-out sway bar mounts and a corroded rear differential housing or liftgate latch. Several say they were told a limited service campaign applied only to vehicles registered in certain states, or that related components damaged during a frame repair were not covered. Mostly reported between roughly 80,000 and 260,000 miles, on older vehicles in daily use.

   What to check: Put the truck on a lift and inspect the frame rails, rear axle housing and body mounts for flaking or perforation; ask whether the frame-rust service campaign was performed and in which state the vehicle was registered.

   “I own a 2001 Toyota Sequoia that I have been told is now un-drivable due to a corroded frame. I find it hard to believe that a 9 year old car would have a rotted frame. I put the car in to the dealership I bought the SUV from and was told that they found rust perforation at two locations but the dealership and Toyota had no recall on the vehicle and could do nothing for me at this time.”

   NHTSA complaint #10293051, filed 2009-11, 154,427 miles

   “My truck would be perfect aside from the major corrosion located on the entire frame. I'm on borrowed time with my vehicle. Toyota should replace the frame before the bottom drops out. The cause of this would probably be cheap parts from the factory.”

   Vehicle speed control

   ABS engages and front brake grabs on one side

   • 177 complaints (33%)
   • median 130,000 mi at 11.6 yrs old (158 state mileage)
   • 5 mention a crash, fire or injury
   • owner-quoted repair $1,250 (median of 22 quotes)
   • filed 2001–2025

   Complaints describe the ABS or traction control applying the right front brake on its own, dragging the vehicle to the right and forcing owners to correct or pull off the road. Some link it to the same yaw sensor or skid-control computer diagnosis as the VSC complaints, and some report the system cutting engine power briefly at the same time. Owners frequently say the dealer could not reproduce the problem or found no stored codes. Reported across a wide mileage range, roughly 65,000 to 240,000 miles, at speeds from about 15 to 75 mph.

   What to check: Ask for any history of ABS or traction-control diagnostics and sensor replacement, and watch for uneven front brake wear or a pull to one side under light braking.

   “While I was traveling on the highway at 70 MPH, the right front brake locked up momentarily and lurched the vehicle, the vsc and traction control light started flashing and a warning buzzer went off. After looking into things, there are known issues with the 2001 and 2002 Toyota Sequoia that cause this exact thing to happen to plenty of other people. I understand that there has already been an evaluation done on this matter and it was ruled that the severity of the issue does not warrant a recall. …”

   NHTSA complaint #11338950, filed 2020-07, 146,000 miles

   “I was driving about 50mph when all over a sudden my car lost power and I heard a grinding noise and was shaking. Then immediately the Sequoia vsc & trac sensor lights turned on. This has happened twice now in the past one week. It's like I almost lost control of the car. It would have been definitely worse if I was on highway. I called Toyota corp customer relation and filed a complaint but they would not admit to have this recalled despite the fact that they have had many safety issue complaints about this problem. …”

   Brakes

   Brake shudder and vibration when stopping

   • 52 complaints (10%)
   • median 86,417 mi at 8.8 yrs old (40 state mileage)
   • owner-quoted repair $2,000 (median of 7 quotes)
   • filed 2002–2023

   Owners describe vibration or shudder through the pedal and front end while braking, especially from highway speed or on hills, with some reporting repeated pad and rotor replacement and warped rotors at low mileage. A few complaints mention a front caliper seizing and overheating the rotor, and one notes a parking brake that would not stay set. Several say a dealer acknowledged a service bulletin covering the rotors but declined to do the work once the warranty had expired. Reported from as little as 8,000-30,000 miles through the 150,000-mile range, often while braking from highway speed or downhill.

   3 related service bulletins

   What to check: Brake firmly from highway speed during a test drive and feel for pedal or steering-wheel shudder; ask for service records showing whether rotors, pads or calipers were replaced and with which parts.

   “I have a 2001 Toyota Sequoia that I have replace the brakes on 3 times in 3 years because of a vibration problem when braking on hills and at freeway speeds. This is dangerous for my wife to drive as she feels like she might lose control of the vehicle when the vibrations are strong enough.”

   NHTSA complaint #10058805, filed 2004-02, 8,000 miles

   “Problems began at 14,647 miles on brand new vehicle. Extreme pull to the right, shimmie, vibration while driving and braking, loss of vsc abilities. Repeatedly have had to replace tires and brakes because of malfunction. Tires are wearing to the metal in unconventional manner. Toyota repeatedly disregarded and dismissed my concerns, telling me the roads in az slant to the right, hence your vehicle will pull to the right . …”

   Transmission and drivetrain

   Transmission and driveline failure

   • 38 complaints (7%)
   • median 98,000 mi at 8.7 yrs old (33 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $3,650 (median of 8 quotes)
   • filed 2003–2024

   A small number of owners describe the transmission failing outright, with one reporting a broken pin inside the unit that damaged it, another a torque converter failure, and another difficulty selecting a gear with a buzzing noise before losing power. Others mention a leaking rear differential housing linked to corrosion. Repairs were reported as expensive, with one owner saying the manufacturer and dealer shared part of the cost outside warranty. Reported mainly between about 60,000 and 100,000 miles.

   What to check: Check transmission fluid condition and for leaks at the rear differential, and test shifts from a cold start plus a highway acceleration run; ask whether the transmission or torque converter has ever been replaced.

   2 excerpts from owner complaints in NHTSA records

   “The throttle body sensor failed numerous times causing my family to lose all acceleration on a very busy highway. I was able to get off the highway and get a tow to the Toyota dealer (david maus) and they thought initially that the whole throttle body needed to be replaced ($2000+) but after the mechanic cleaned the sensor it resolved the issue thus far, its been three months without recurrence. I want people to know this is a cheap fix as I believe others noted here that the dealership only offered replacement as a solution. …”

   NHTSA complaint #10193318, filed 2007-06, 61,000 miles

   “The vsc light came on after my 2001 Sequoia hit a pot-hole. This was back in 2004 and the light remains on. I was told it was a sensor. The vehicle is long out of warranty and I can't afford any expenses right now. That's just one of a few major components to go. In 2003 the torque converter went and the transmission had to be replaced. I had 88,000 miles on it and it was beyond the 60,000 drive train warranty. However, Toyota did pay for half of the $4000 bill with the dealership picking up a 1/4 of the bill. I paid the rest. …”

   NHTSA complaint #10254951, filed 2009-01, 120,000 miles

Buying note. On a truck this old, the VSC/TRAC behavior and frame rust matter more than mileage: drive it at highway speed on dry pavement and inspect the frame on a lift before buying. Ask for service records on brakes, stability-control sensors and the frame-rust campaign.
