When the electric power steering warning comes on..... the car slows to a halt with no gas...... why and what can I do?

My car has 326000 miles.
My car has an automatic transmission.

Hi there. Are there any other lights illuminated? When the EPS light does come on, the electric steering system has detected a fault and can cause the vehicle to proceed into what may seem like a limp mode; we wouldn’t want a steering problem at high speeds, right? There are several things that could cause this: failed or overheated steering motor, low hybrid battery charge, wiring harness faults, internal circuitry faults. Due to this being a hybrid and involves the possibility of a high voltage accident, please do not attempt to diagnose the system yourself; a hybrid certified technician should be acquired to perform an inspection to avoid an accidental high voltage shock and avoid replacing unnecessary parts. Toyota did issue a recall last year on several of these models and you may need to have this checked via the NHTSA at (https://www.safercar.gov/Vehicle-Owners/Check-For-Recalls/CheckForRecalls); these are government mandated recalls. Toyota has another classification of recalls that are not government mandated called "special service campaigns" and these may not be listed at the site quoted; these you may need to check with the local Toyota dealer. In the meantime, Your Mechanic has hybrid certified technicians that can assist you with an EPS light inspection; be sure to state that the EPS light is illuminated.
