This is a common issues with 2016/7's and is usually addressed by replacing the O2 sensor. It is still under warranty.I have a 2017 Cruze Hatchback, 17,500 miles. Recently the CEL came on and I read a P015b code. After reading a description of the code, O2 sensor slow to respond, I simply chalked it up to the fact that the CEL lit during a warmup and I cleared the code. Is this actually an indication of a bigger problem that I should send the car to the dealership for repair? I do a lot of my own wrenching but don't have the expensive bi-directional diagnostic equipment. Is there something that I could inspect/checkout on my own? I've read where shops have performed PCM flashes and replaced catalytic converters and all sorts of throwing parts at the code. I'm not a fan of that type of troubleshooting.
