I had failed to post an update on my dispute over warranty repairs to my 2008 Altima Hybrid. After contacting the Pennsylvania State Attorney General I received a notification from Nissan that they would replace the head and other related parts. Porreco Nissan preformed the work. I now have over 70,00 miles on this car and it has run without problem. I am well pleased with gas mileage and performance. To bad Nissan failed to continue with hybrid technology as it makes the trip from Erie, Pa to Connecticut and Chicago without stops for recharging or fuel ups.
