My wife and I got our 2002 Toyota Sequoia brand new in 2002. Just this past week, the vsc and abs light comes on. We took it to the local Toyota dealer and found not only do those lights need replacing but also the brake booster. Total cost about $1900. I've done research on this problem on the web and found on a website, tundrasolutions. Com, there were a number of people with the same problem. Anywhere from 50k to 80k miles on their 2002 Sequoia and the same problem happens. When we took it to Toyota, they said that was a very rare problem for a car with that mileage. Toyota, the manufacture, or the local dealer would not take any responsibility for the parts and that it wasn't faulty parts. We got it fixed today. The local dealer knocked off 25% of the price. We feel like this is a problem Toyota needs to pay in full. If this many are having this problem, then there's a problem.
