Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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. …”
NHTSA complaint #11386700, filed 2021-01, 137,200 miles“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. …”
NHTSA complaint #10863990, filed 2016-05, 167,000 miles“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.”
NHTSA complaint #10914104, filed 2016-10, 252,500 miles“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. …”
NHTSA complaint #10523028, filed 2013-07, 101,000 miles“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.”
