Codes read are P2716 and PO60X and most of the problems are cars made in NUMMI and ECUs made by Delco. Codes fall under federal emissions warranty of 8 years or 80K miles and Toyota has several TSBs out on this serious issue. If you are out of warranty, new ECU costs $700.
We had this experience with our 2006 Pontiac Vibe (same as Matrix) at about 60,000 miles. Luckily we were under the 80K warranty as we needed a new ECM. Just sold the car with 85K on it and other than that and a squeaky fan motor it was a fantastic car.
