I think there's a correlation between the TSB caliper/rotor upgrade for 01 and 02 Sequoias and the VSC computer failures that seemed to common for those model years. I wonder if Toyota updated the VSC computer when they did TSB brake upgrade. I did read a long term test drive review on
edmunds.com on the Sequoia 2002 model where the VSC lights came on and when taken to the dealer it was attributed to low brake fluid. Perhaps it was it a sign that the VSC computer was about to fail. I do think that VSC computer failure could be a safety issue and NHTSA should investigate this matter.
I do have to thank my dealer and Toyota for stepping up to the plate and repairing my VSC computer for free. I love driving my Sequoia 4x4 offroad and consider it a quality built SUV.
