Component Failed & Availability: The engine on my 2015 Toyota Sienna (99,000 miles) catastrophically failed and is completely seized. The vehicle and engine are in my possession and are fully available for physical inspection. Safety Risk: The vehicle shut down completely while in motion, causing an immediate loss of motive power, power steering, and power braking assistance. Had this un-warned seizure occurred at highway speeds rather than a parking lot, the sudden loss of vehicle control would have posed a severe crash hazard. Reproduced/Confirmed: Yes. A certified mechanic removed the serpentine belt, attempted to turn the engine with a lock bar, and confirmed the engine block is completely seized. The local dealership, Fred Haas ToyotaWorld, also confirmed the vehicle does not run. Inspections: The vehicle was inspected by my independent mechanic and the local dealership. However, Toyota Corporate formally refused my request to dispatch a field engineer to inspect the defective engine. Prior Warnings: There were absolutely no warning lamps, check engine lights, temperature spikes, or abnormal noises prior to the failure. The engine seized instantly and without warning.

My engine caught on fire. We had seconds to get out prior to it engulfing in flames. Fire department had to extinguish. Not sure what caused it. The entire vehicle caught on fire. There was an engine light warning I had the vehicle repaired but the warning light was not cleared

There is an EVAP emission leak and the P0456 error states the gas cap is faulty. I had it replaced and replaced again. So I am waiting for another brand new gas cap-3rd brand new one. So 4th overall for this van. A smoke test was done and there is no leaks per the test. So if this continues after the brand new gas cap, then there should be a recall as the gas cap is an issue. Started to happen after 95,000 miles. The AWD is shut off and goes to 2 wheel drive, traction control is turned off, Check Engine light comes on and Message Check AWD system comes up on the screen. Any recommendations

The intake valve became burnt/stuck, causing my car to lose all compression on cylinder 3. The CEL came on, flashing, and the car immediately started driving rough and not accelerating. I had the vehicle brought to 2 different auto shops that confirmed the issue. My and my childrens' safety were at risk as soon as we tried to turn right onto a high speed road and my car started the flashing CEL and would not accelerate. There was no warning before this incident.

Van would reboot while parked or driving. It started with dashboard rebooting then I couldn't start the van. There was a time after driving I put the van in park and turned it off but my van was moving on it's own. I always call the dealership when the rebooting occurs. I was told either it was a software issue or since the problem went away, I should be fine. Well recently when my van stalled and had to be towed to the dealership. I was told it was a battery issue and the battery was replaced. When I picked up my van and went home, noticed my rear view camera would not come on went I put the van in reverse. Called the dealership to tell them what's going on and the service advisor woman was very rude and stated it was battery and they never checked anything else. I stated to the woman the I've always expressed my concerns about the van rebooting, won't start, or moving on it's own. The woman became very rude and hung up on me. I decided to go right back to the dealership on the way there I called back to speak to the manager of service department to explain what's going on. While driving there the check engine and another light turned on. Shortly after that as I was turning left, while in the middle of the intersection my van stalled. The steering wheel and brakes locked and the van completely shuts off. I was locked in my van with no control over the van and it was moving towards a pole. Luckily the van stopped before hitting anyone or anything. I was on the phone with the service manager the entire time. The manager called for someone to pick me up and called a tow company. I asked the manger if they are stating my issue was a battery and a new battery was installed why am I still having the same issue. The police was call because someone reported my van in the middle of the intersection.
