What stands out
Of the 4 model years of Toyota Sequoia we track for powertrain problems, this one carries the most owner complaints on file — 12.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
TechTip: Condition - The vehicle may be difficult to start or have an abnormally low or rough idle after the battery has been disconnected or power to the Engine ECM has been interrupted.
full bulletin at NHTSA ↗TSB: World Standard (WS) Automatic Transmission Fluid (ATF) was introduced to reduce maintenance costs and increase the mileage between scheduled maintenance checks. Here are some important tips when working with ATF-WS in Toyota vehicles requiring it's use.
full bulletin at NHTSA ↗TSB: The purpose of this bulletin is to provide information regarding transmission and/or park neutral position switch installation. If the manual shift lever is rotated prior to installing the park neutral position switch, the detent spring may become detached from the manual shift lever.
full bulletin at NHTSA ↗TSB: The purpose of this bulletin is to provide precautions to follow when installing an automatic transmission/transaxle assembly to avoid MIL "ON" shifting issues and/or transmission damage. Use the information in this bulletin when installing an automatic transmission/transaxle assembly.

The failure pattern owners describe
Owners of 2005 Sequoias report four distinct powertrain problems. First, a violent clunk or lurch from the rear when releasing the brake to accelerate—described as feeling like being hit from behind—happens daily and multiple times per session. One owner had the transmission support and crossmember replaced by Toyota; the problem continued. The dealer later claimed this was normal and unfixable.
Second, transmission jerking paired with simultaneous illumination of check engine, VSC TRAC, VSC OFF, and brake warning lights. This occurs at various mileages, sometimes limiting top speed to 30 mph. One dealer stated both the VSC computer and transmission were defective but didn't repair the vehicle.
Third, transmission grinding, power loss at highway speeds, vehicle stalling in drive, and clunking during reverse. One owner noted a recall existed for a bad computer in 2004 models (this is a 2005).
Fourth, transmission lock-up during deceleration at 30-45 mph, where the vehicle refuses to coast and stays at elevated RPM for 4-6 seconds before releasing. A dealer observed this behavior but offered no solution. No owner found recalls matching their VIN despite widespread internet discussion of these problems.
Failure modes owners describe
Transmission clunk/lurch on brake release and acceleration
When coming to a complete stop and releasing the brake to accelerate, owners report a clunk or violent lurch from the rear that feels like being hit from behind. Occurs daily, multiple times per day. One owner reported an increasingly loud thud that corresponded with vehicle speed after hard braking. One dealer diagnosed a faulty transmission support/crossmember; replacement did not resolve the issue.
When: During stop-and-go driving; appears to increase in severity with harder braking
Symptoms owners cite: Clunking or lurching sensation from rear during acceleration after braking; Feels like vehicle has been hit from behind; Occurs multiple times daily; Louder thud following harder braking events; Thrust into headrests during hard braking scenarios
Codes mentioned: VSC OFF, VSC TRAC
Repairs/costs cited: One owner had transmission support, crossmember, bolts, and insulation replaced by Toyota; problem continued. Updated crossmember and bolt offered at subsequent visit without repair being performed.
Recalls/TSBs owners mention: Toyota initially told owner this was normal operation. Later claimed it was a drivetrain problem that cannot be fixed and owner must live with it. Dealer advised TSB or updated parts available but repairs did not resolve the issue.
Transmission jerking/hesitation and power loss with check engine and VSC lights
Transmission jerks, hesitates, or loses power during acceleration or normal driving. Check engine light, VSC TRAC light, VSC OFF light, and brake warning lights illuminate simultaneously. One owner reported 30 mph top speed limitation when TRAC VSC and OFF TRAC PLUS modes were active. One dealer advised both VSC computer and transmission were defective.
When: Varies from 45,000 miles to 87,000 miles; occurs during normal driving and acceleration
Symptoms owners cite: Transmission jerking or hesitation during acceleration; Engine lurches forward; Loss of power during hill climbing or freeway driving; Check engine light illuminated; VSC TRAC light on; VSC OFF light on; Brake warning light on; ABS light on; Severe power loss limiting top speed to 30 mph
Codes mentioned: VSC TRAC, VSC OFF, CHECK ENGINE, BRAKE warning, ABS
Repairs/costs cited: One owner reported needing transmission replacement at significant cost. One dealer advised VSC computer and transmission were both defective but vehicle was not repaired. One owner reported Toyota mechanic cited bad computer previously recalled in 2004 models.
Recalls/TSBs owners mention: No recalls found in owner's VIN search for this issue despite widespread complaints. Warranty had expired on at least one vehicle when problem occurred (45,000 miles).
Transmission grinding sound and power loss at highway speed
Transmission makes grinding sounds during operation. Vehicle loses power while traveling at highway speeds, with VSC light illumination. One owner reported loud clunk when backing up and no power getting up hills.
When: During highway driving and reversing
Symptoms owners cite: Grinding noise from transmission; Power loss at highway speeds; VSC light comes on; Loud clunk when backing up; No power on hills; Vehicle stalls when put in drive
Codes mentioned: VSC
Recalls/TSBs owners mention: One owner noted bad computer previously recalled in 2004 models per Toyota mechanic, though this vehicle is a 2005.
Transmission gear locking issue during deceleration
When foot is removed from accelerator at speeds between 30-45 mph, the transmission does not coast normally. Instead it decelerates harshly as though stuck in a low gear, with RPM remaining elevated at 1600-1700. After 4-6 seconds the transmission releases and allows normal coasting with RPM dropping to 1100. Dealer observed the complaint but had no answer.
When: During deceleration from 30-45 mph with foot off accelerator
Symptoms owners cite: Harsh deceleration when foot off gas; Elevated RPM (1600-1700) during deceleration; Delayed release (4-6 seconds) before normal coasting begins; Normal RPM (1100) after release occurs
Repairs/costs cited: Dealer observed the complaint during test drive but offered no diagnosis or repair solution.

Common questions
How serious is the powertrain problem on the 2005 Toyota Sequoia?
It's a serious issue. 12 complaints have been filed and 2 fatality(ies). We've classified it as critical based on NHTSA's reported outcomes.
At what mileage does the powertrain typically fail?
Across the 10 complaints that reported odometer mileage, most powertrain failures cluster between 63,520 and 89,000 miles, with the median around 68,000. A quarter of owners report trouble before 63,520; a quarter make it past 89,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $2,500 for powertrain repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to powertrain?
No active recalls currently cover powertrain issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
