“I own a 2006 Toyota Sienna le with only 26500 miles on it. I was driving my car on the highway doing 45 miles per hour on a dry pavement on tuesday 09/03/2019 around 6:40 pm and at a sudden moment the vsc light started flashing, warning sound came on, the car applied the brakes on its own hard until it fully stopped, and the engine shut off by itself, which almost got me into an accident. …”
NHTSA complaint #11253811, filed 2019-09, 26,500 miles“Check engine light, vsc light, traction control light. All 3 lights came on at same time. They say it's the gas cap, it's not the gas cap, they say to reset it, that doesn't work. I was driving home, nothing happened, the lights just came on. No warning sound, nothing to indicate there was a problem, my car seems to drive just fine, but the lights won't go off, and I have 3 kids that I take and pick up from school”
