My 3.0 engine runs very well, idle is smooth, getting 17.6 mph, has plenty of power but this code pops up 177,000 miles on it I am the second owner I bought it with 152,000 miles on it. Is it possible that one of the sensors went bad?

Google the code number and you should get info on what it may be? I had a DTC #0152 last year on my 2016 Terrain and it was specifically related to my oxy sensor going bad. Replaced the sensor cleared the code and no issues since. BTW my GMC Terrain only had around 38,000 miles on it last year at the time of issue.
