Purchased the car new in September 2014. At around 12,000 miles, the catalytic converter & 02 Sensor had to be replaced.

I am annoyed that the warranty for emissions only lasts til 80,000 and mine just went out right after that, even though the car is 3 years old. The dealer said it is a VERY COMMON problem on the Encores. After having an Enclave and all the problems it had, I will never have another Buick.
