Five problems related to brake antilock control unit/module have been reported for the 2001 Toyota Sequoia. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2001 Toyota Sequoia based on all problems reported for the 2001 Sequoia.
Normal vehicle usage with only 66,000 miles and all abs, vsc warning lights are on with anti-lock and anti-skid computer disabled resulting in no abs or skid control. Dealer reports to me that it is a $2,200 "computer" needing replaced, only 6,000 miles out of powertrain warranty. Call to Toyota corporate was of no value, dealer and Toyota refuse to provide any assistance.
Vsc trac/vsc off lights intermittently turns on, regardless of driving condition, speed or weather.
1) overly sensitive trac computer will cut power when merging into traffic, causing a potential situation for an accident. 2) trac-off and vsc-off lights will illuminate, fault codes show that vsc computer needs to be replaced, leaving the vehicle without traction control or stability control or abs brakes. Manufacturer will not cover unless still under bumper to bumper warranty. Happens at least once per week.
Traction control system (vsc/trac) will intermittently not function for no apparent reason, causing vsc/trac lights to illuminate and potentially compromising vehicle safety. Diagnostic check of vehicle reveals a problem with the brake booster and/or a sensor within the brake booster assembly that is prone to intermittent failure on this vehicle. Replacement of the parts in question are prohibitively expensive (over $1,000) and only covered up to 3yr/36k mile on the vehicle. There is a definite failure trend present in this particular vehicle and Toyota knows about them, given the tsbs that exist for this problem. This issue needs to be addressed as a recall to ensure all vehicles, especially ones out of warranty coverage, are repaired properly.
Anti- skid control system mode solenoid sensor/ abs brakes can activate at any random time. Contacted dealer, and dealer stated there was nothing wrong with vehicle. The skid control system activated five times during the first week of puchase, but had not occured since. However, the consumer does not feel confortable because of possibility of reoccurence.
