ECU in 2001 Prius failed at 103,000 miles

Misery loves company. After a nearly $1,300 repair bill for a new ECU (and 3 trips to pass inspection, along with a new O2 sensor), I'm interested to know if this is a very rare situation -or if Toyota has a systemic issue with the Prius. Any others out there? Toyota's ECU warranty expired after 80,000.

I had 02' Prius and it had ECU. Last year, it stalled in the parking lot. It won't start and dealer didn't find out any wrong with it. They just reset ECU. Last week, the car showed up the Hybrid System Error again and it didn't satlled. I managed to get the car into dealer and they found out it was ECU and fuel relay. ECU is covered under warranty but Fuel relay isn't. They told me I had to pay $150 for fuel relay.(labor was included). Last week, I traded in that car for new 06 Prius and they told me I didn't have to pay for fuel relay. They took care the repair bill.

I have a 2002 Prius, for several years it would show "check engine" signal, and I would get various explanations from service department. ie Gas cap not tightend, battery too small, a leaf got pushed into some internal sensor, we dont know and we are not getting any signal, everything seems to be Ok. etc. Car is now at a different service department in Ukiah California, they have taken the problem seriously, checking and rechecking everything, keeping the car for over a week and finally getting some repair code. Prius is under extened warranty and they are installing new ECU at around 86k miles. I think the problems has been evident for the past several years, with random unexplainable symtoms and 5-6 trips to service to try and fix.

Our 2002 Prius ECU went away at about 55-56,000, it had bobbled before at about 40K but was reset. After the initial reset the mileage wasn't as good as it had been prior to the bobble. After the ECU was changed the milage is back, but we're a little leary of the car. Thinking maybe we should be considering turning it into a Yari, mileage would be about the same but without a $1500 ECU hanging over our head. We commute about 80-100 miles a day driving the Sipper to work, the miles stack up and with the $2.90+ a gallon gas really makes a heck of a difference. Hmmm, to remain Hybrid or Opt for a small smart gas rig. As a note I went on the web the second time it had a conniption fit and found instructions to reset the semi-dead ECU. It worked well enough to save the $200.00 tow bill to the dealership, warranty covered the ECU.
