P0455 code 2015 C7 19000 miles
I think the code is an “evaporative leak detected”. Is anyone aware of any C7 issues with this code or any obvious places that leaks occurs. Most of the miles on this car are in town driving around 30 mph. Thanks in advance for any for any comments.

I believe the P0455 is a “large” leak detected that can be anywhere in the EVAP system…a hose, a vent valve stuck open, a gas cap but I dont remember if the 2015’s have a cap less system…take the car to a diagnostic shop not a dealership or general repair shop…most are clueless when it comes to diagnostics !!
