Got an oil change about 3 weeks ago at a Nissan Dealership and drove the car about 100 or so miles - no issues. Went out of town - came back and drove it a couple of times no problems and then the Service Engine Soon light came on. Took it to same dealer - was told it was the OS2 sensor got it replaced under warranty. Drove it 25 miles - stopped at store - got back on road - got gas - light back on. Was told by dealership (make sure gas cap is on tight) verified that and still no cigar - same problem. Light is on.

Any thoughts, suggestions??

 

get the code pulled for free at Autozone and let us know what # it is.

 

Taking it back to Nissan dealer tomorrow and get them to give me the error code as well.
