2010 Nissan Altima Sedan 2.5 S 4dr Sedan (2.5L 4cyl CVT)
Bad Engine and a lot of issues
 End of July 2010 bought car with 32000 miles on it. 1st week of November car went into shop, 39000 miles now, my mechanic said top of the motor was bad & needs to be torn down to see what was wrong. Was under warranty so I took it to the dealer. The dealer started the car listened to it for 5 min & then told me the engine had oil sludge. Told them no way it had sludge. I called nissan consumer affairs. They paid for my rental & repairs. took the engine apart-no sludge-engine was bad. I needed a new longblock engine for the car. The new engine they ordered was cracked so they ordered another one. Bottom line it took 3 wks to get my car back. Hope this engine last longer then the last one.
