Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical 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.
TT: Some customers may encounter Bluetooth® connectivity concerns such as: ?Difficulty to pair the phone. ?Intermittent Bluetooth® failure to connect to the vehicle when first turning on the vehicle. ?Various Bluetooth® Audio functions are no longer functioning with customer?s phone such as ability to change the track using the steering wheel controls. These concerns can be caused by changes made on the customer?s phone. Make sure to inquire with the customer if the connectivity concerns occurred after receiving an operating system update on their phone, or if they have restored their phone data/settings recently.

Any previous printed versions of this bulletin should be discarded. In the event that a Toyota vehicle becomes submerged in water, many components may be physically damaged. Electrical and electronic components, including wiring harnesses, are particularly susceptible to corrosion and subsequent malfunction. Although any flooding can be damaging, salt water flooding elevates the potential for abnormal conditions and may increase risks due to its highly corrosive and conductive nature. Salt residue also continues to corrode and remain conductive even after a vehicle dries.

The failure pattern owners describe
Owners describe a range of electrical complaints affecting the 2007 Sequoia. Battery corrosion and leakage is the most serious—one owner discovered acid leaking from a faulty battery that corroded the entire engine bay, but Toyota dealerships refused warranty repairs, claiming user-filled water (owner disputes this) or citing out-of-warranty status despite the issue being reported during the warranty period.
The tailgate latch is a chronic problem: plastic parts fail repeatedly, with one owner forced to manually unload heavy camping gear through windows after the latch failed, causing back and hand injuries. Toyota is aware of the weak engineering but no longer covers repairs.
VSC and TRAC warning lights come on repeatedly—often together with brake lights—but disappear when the vehicle is turned off, preventing technicians from reading diagnostic codes. One owner reported sudden power loss at 40 mph with hard steering and stalling, recurring every few days. Another noted the brake does not override cruise control on the highway, allowing continued acceleration despite braking.
Key fob door locks fail intermittently; doors require manual locking. The secondary air injection pump fails at costs up to $3600, though Toyota extended warranty coverage only for 2008–2010 models with the same engine. Minor electrical fires were also reported: one from a driver-seat heating switch and another involving a power window motor that seized and disabled the rear defogger.

Failure modes owners describe
Battery corrosion/leakage
Battery leaks and corrodes engine bay. Fan circulation spreads acid throughout engine compartment, leaving corrosion pattern on hood underside and engine bay surfaces.
When: January 2010 observed, issue reported March 2010 during warranty period
Symptoms owners cite: Corrosion visible on underside of hood; Corrosion throughout engine bay; Battery leaking
Repairs/costs cited: Dealership at Elk Grove identified battery as faulty and leaking. Owner requested hood repainting and new battery; repair estimate submitted but denied.
Recalls/TSBs owners mention: Mid City Toyota denied warranty claim citing user-filled battery water (owner disputes). Elk Grove Toyota denied repair citing out-of-warranty status as of 6/24/2010, lack of maintenance records, and no good-will coverage despite complaint opened during warranty period (Case #1007162060).
Tailgate latch failure
Plastic tailgate latch fails repeatedly and does not open reliably. Dealership noted Toyota is aware of weak engineering and poorly designed plastic part prone to failure when exposed to dust.
When: At least one prior replacement one year before second failure event
Symptoms owners cite: Rear latch will not work; Tailgate will not open
Repairs/costs cited: Latch replaced, cleaned, lubricated, and temporarily sealed with plastic bag by dealer. Owner reports chronic failure pattern.
Recalls/TSBs owners mention: Toyota no longer stands behind repairs to this vehicle's tailgate latch due to chronic problems and lack of improved replacement parts.
VSC/TRAC/Brake warning lights—intermittent, code-clearing issue
TRAC OFF, VSC TRAC, and brake lights illuminate repeatedly during or after braking. Codes clear when vehicle is turned off, preventing diagnosis even at dealership.
When: Occurring several times while driving; extended warranty expiring within two months of complaint date
Symptoms owners cite: TRAC OFF light comes on; VSC TRAC light comes on; Brake light comes on; Lights come and go frequently; Lights disappear when car is turned off
Codes mentioned: Codes clear/not visible when car is powered on
Recalls/TSBs owners mention: Two Miami-area Toyota dealers unwilling to diagnose or repair without stored codes. Dealers stated computer does not show codes while car is on and resets when car is turned off.
VSC/TRAC off with sudden power loss and hard steering
While driving at 40 mph, engine power suddenly drops, steering becomes hard, VSC OFF and TRAC OFF lights illuminate. Vehicle stalls completely. Issue recurs within minutes or every few days. Described by owner as common problem in first-generation Sequoias affecting skid control system.

Symptoms owners cite: Secondary air injection pump failure
Repairs/costs cited: Repair cost can reach $3600 per owner estimate.
Recalls/TSBs owners mention: Toyota extended warranty on 2008–2010 Sequoias with same engine but denies coverage to 2007 owner with identical engine.

When: Lights came on overnight; described as seen back to first generation
Symptoms owners cite: VSC TRAC light comes on; TRAC OFF light comes on; Check Engine light comes on; Brake does not override cruise control; Vehicle continues accelerating under cruise control when brakes applied
