1 Engine And Engine Cooling problem

Failure Date: 12/21/2020

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.

3 Engine And Engine Cooling problem

Failure Date: 04/01/2016

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. I took my vehicle in to get it inspected and they provided me with 3 codes: c1203 - engine control system communication circuit malfunction c1360 - vehicle skid control master pressure sensor malfunction p0420 - catalyst system efficiency below threshold these are all system issues. Can you help me?.

7 Engine And Engine Cooling problem

Failure Date: 04/20/2013

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.
