The vsc / skid controller is not operating properly. My daughter took the 2005 Sequoia SR5 to the dealer. A diagnostic test indicated that the skid control logic circuit was bad. The dealer offered to replace the computer for $2700 I declined the repair because of the price for the repair. I bought this truck last year (2008) and this is the first problem that I have encountered. This is a safety item that Toyota should correct before some one gets seriously hurt.

On my 2005 Toyota Sequoia, on my dash board the vsc off, vsc trac light came on. When these lights come on there is a computer failure and you could los econtrol. There is a 'service bulletin' dating back to 2003 that Toyota is aware of computer failure concerning this issue from what I found out on the websites.

Our brake indicator light on dash comes on intermittently since mid 2008. We've taken to the local Toyota dealer 3X to diagnose. On the third visit, the service rep said the skid control computer needs to be replaced. He said when light is on, the antilock brakes will not work, nor the stability control. The estimate to replace is $2425 installed for a new skid control computer. We know of at least two of our friends that are having the identical problem. This is obviously a faulty computer and a safety issue and needs to be recalled asap.

My mother owns a 2005 Toyota Sequoia. I'm not sure how this works but it is only four years old and the brake light comes on then the skid control comes one. When she took it to the Toyota dealer they told her that their was a service bulletin for this and that it was a well known issue with the 2003-2005 models. If im not mistaken congress passed a law stating that all vehicles starting with a certain year has to come with stability control. Toyota knows this is a problem and an expensive problem. They want a little over three grand to fix it. I would understand if this was a random event but this is a safety issue and it is a problem well known to Toyota.

Vsc, track, and brake lamp stay on. Toyota has not repaired problem. Was first brought to them in warranty when they said they had to replace the computer but didn't have the part. They have since replaced the computer but the problem persist. Now they say it is a master cylinder sensor (2 of them) but still have not repaired. When first brought to them, I was told this was a common problem. Have since noticed that the internet is filled with this same problem. This affects traction and is an obvious safety problem and should be recalled. This problem has continued from 2005 to present.

I have a 2005 Toyota Sequoia with 56,000 miles on it. Over the past month the dash board brake warning light has started coming on. I took the truck to the dealer last week, sterling mccall Toyota in houston, Texas. The dealer diagnostics revealed a error code on the computer of C1247 stroke sensor failure. After a day the light came back on. The dealers response was that a $2,300 ECU was required to correct the problem. If you look online there are hundreds and thousands of similar complain on this vehicle. Something has to be done!

I have a 2005 Toyota Sequoia with 36,000 miles on it. Over the past month the dash board brake warning light has started coming on. I took the truck to the dealer last week, arlington Toyota in jacksonville Florida. The dealer diagnostics revealed a error code on the computer of C1247 stroke sensor failure. After a $100 adjustment of the brake light switch, with in a day the light came back on. The dealer's response was that a $2,300 ECU was required to correct the problem. I am amazed that a vehicle with 36, 00 miles and less that 4 years old could require a part that expensive. Doing a little research on the internet it is clear that this is a systemic problem Toyota trucks. An internet search will return pages of 'hits' covering several model years of Toyota trucks from hundreds of victimized owners. Most of those posts detail owners being taken for thousands of dollars by Toyota service departments as their technicians struggle to correct the problem by replacing multiple very expensive parts. In my mind, this is clearly something the government needs to get involved in, as quickly as possible. I do not know if there is a safety issue here. To me a sensor detecting an issue with a vehicles breaking system is not something that should be ignored and the manufacturer should be required to correct this clearly systemic problem with one of their products.

I have a 2005 Toyota Sequoia limited 2wd. At random times the vsc dealership, vsc off, ABS, and parking brake lights all come on at once. They will stay on until I stop the vehicle and turn the ignition off. When I restart the truck they will function normally. There are many theories of why this happens, but my dealership says nothing is wrong. I am worried about a costly repair when I am out of warranty or a potential safety issue. I have had the truck at the dealership multiple times and they say they can't find anything wrong.
