Carrier/rack problems of the 2003 Toyota Sequoia

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.

Tree lights came on, svc, track off and abs. That will cost around $1150. Plus taxes. That I think is not right because it's been many complains about this matter. And for this mileage it shouldn't be the time please we need help because if we get minimum wage than we won't be able to afford it. Please help.
