2015 Sienna accelerating on its own from dead stop

Hey everyone,

Was hoping I could get some input from members here

Today I noticed while approaching a red light that when I took my foot off the gas, it was still being indicated on the "Instant MPG" that the van was using gas. In the past, whenever I take my foot off of the gas, the instant MPG will indicate 0 L/100 km

I pulled over to a side street and came to a full stop, took my foot off of the gas, and the van accelerated on its own to nearly 30 km/h. I was not on a downhill slope. I turned the van off, waited 30 sec, and turned it back on and the issue went away.

Kindly see following link to video:


Any idea why this is happening?

Isn't all cars like that no matter if its automatic nor manual transmission?

... except may be expensive cars that has downhill/uphill brake control thingy...

I never got that kind of money to spend on cars, so I never had one that automatically applied the brake when you're stopping.

I think that amount of acceleration and speed is to be expected when the brakes are released and when the vehicle has an automatic transmission.
The 30 kmph speed is only about 18 1/2 mph.
