I have had problems with my 2001 peius for the past year with the engine stoping at freeway and local highway speeds. My car has now set at stanger Toyota in st. George for the past month with no cure for the problem. The dealership has installed a new inverter, traced all wiring, reset codes and still we have the same problem of the car quiting or going into stelth mode. The car is no longer reliable on trips over one hour. The problem has happened in high and low temp. Conditions. My dealership says their is nothing left for them to do and I will just have to keep driving the car and bringing it back to reset the warning lights. This is nuts! Toyota should recall this car at once, it is unsafe, unrealiable and a disgrace to own. I have been a Toyota owner for the past 30 years and have always "loved my Toyotas" but the Prius is a nightmare, and I hope the nhts will investigate this on going matter with the Prius and push Toyota for a recall to fix this problem once and for all.
