My car is equipped with a 2zr-fe engine and it is known issue for all those engines as it exhibit a mil "on" with dtc p219a (bank 1air-fuel ratio imbalance) present. Same issue with most 2012-2014 Corolla which has above engine plus 2012-2013 matrix (Toyota) vehicles this is very dangerous as whole engine vibrats and it makes trac off plus car will breakdown any time on the road way resulting critical situations.
While making a left hand turn off of a busy street, the car slowed to an unsafe speed and was dangerously slow to accelerate. This has happened several times since then with the most recent on February 11, 2014. Toyota maintains there is nothing wrong because it happens at intermittent times and can't be duplicated in the four times it has been taken in.
