Engine & coolingFire

On 12/21/2020, after running errands, I put my vehicle inside my locked garage at 10:30 a.M. And all was fine. At around 9:00 p.M. That same night, I opened my garage to find it full of smoke. After inspecting everything, I saw nothing was still on fire and waited until the morning to investigate the problem. I first tried to start the vehicle and it had battery power but would not turn over. I then put it in neutral and backed the vehicle away from the front of the garage to open the hood. I saw the engine had...

burned up from somewhere on the passenger side but had put itself out. The fire cracked the exterior hood, burned hoses, electrical and other areas of the inside of the engine. Black soot had also dropped on the floor of the garage underneath where the fire was. The wood beams inside my garaged were also scorched black from the intense heat from the fire/smoke but luckily had not caught fire. I had it towed to my mechanic who said I should have my car insurance take over. Mercury has not determined the cause of the fire but I am pushing for the exact cause since if it's related to a recall issue, then toyota should be held accountable and I should be compensated. My vehicle has 37,200 miles less than the average and I have a spreadsheet of all scheduled maintenance, smog checks and recalls completed. There was no reason this vehicle should have spontaneously combusted inside my garage. Luckily, I wasn't driving, wasn't hurt, and no other property was damaged due to this problem.

Vsc, check engine, brake lights keep coming on. No traction control when button pushed. Driving highway speed traction control beeps when not even appropriate. Have had several times trying to brake, no brakes light comes on almost crashed due to no brakes! I have researched recall my vin# not listed. This is ridiculous! Unsafe! Toyota needs to recall more vehicles. Not a happy toyota consumer!

I have a 2003 sequoia with 253,000 miles on it. About a month ago, while driving on a flat, dry road at about 30 miles per hour and slowing for an upcoming stoplight, my vsc off, vsc trac and check engine lights all suddenly came on. Apparently this is a known issue with this year vehicle. I am struggling now to figure out how l will afford to take this car in for repair and l am angered at being put in this position. This was an expensive, luxury suv when we bought it and the manufacturer should own up to this bad part. If I'd wanted a crappy made car, l wouldn't have wasted $40k on this one.

Hello, I have a 2003 toyota sequioa where the engine light and the vcs lights are both on. I saw on your page some really helpful information on this make/model recall. I've reached out to toyota customer service because there was a recall on this make/model but they said that my vin number was not part of that recall, even though it's having the same issues?? The recall was that toyota had to replace the skid control engine control unit (ecu) and upgrade program logic in its vehicle stability control (vcs) system....

While driving on the street at speed limit the car shuts off without any warning. You have no way to break but to place your car in park. I have had this happen twice not sure why it keeps happening. This is very very dangerous.

I was driving down the highway and my vsc trac lights came on along with my engine light. When I got home, I looked at my vehicle manual to determine what had happened. I attempted to remedy the problem as suggested by toyota, unfortunately, nothing changed. Approximately 2 weeks later my brake light intermittently turned on & off. Less than 5 months earlier, I had my all of my brakes replaced, so I can't imagine that my brakes are faulty. I became alarmed by these electronic miscues - so I went online to...

explore whether this was a common thread with other sequoia owners. I discovered very quickly that there are many people who have had problems with their vsc / engine / and brake lights becoming activated. I was hoping this problem might be covered under a recall, but it appears that it is not. I am hoping for a remedy that won't have extensive costs to me. *Tr

I noticed oil leaking from rear axle housing. When I took the vehicle in for service I was told that the axle housing is leaking due to defective welds and must be replaced, it cannot be repaired. At the same time I was also told that the vehicle frame has rotted from the inside out due to defective or inadequate factory rustproofing. I was told that this problem is pervasive in toyota sequoias which have the same frame as toyota tundras. Toyota has recalled the tundras and replaced the frames but to date...

2003 Toyota sequoia will unexpectedly loose power when turning and then acceleration races up after a long pause. This has happened about once per month since purchasing the vehicle in 2003 and has several times resulted in near-miss crashes from approaching traffic as the vehicle will not move out of the way of oncoming traffic. *Tr
