10-15 miles is not enough to get the monitors to run. I usually take a customer's car home at night if I need the monitors to run. They will run on the trip into work in the morning. They may have forgot to reset the adaptive memory, but if the light is back on after that was done, it sounds like you need to have a talk with the service manager to request that a more experienced tech be assigned the job. Are the same codes coming back?

 

Well, I wasn't told any codes. I let them handle the issues but I am not sure what the problem is now. I will see what they have to say about it on Monday since they are closed. I never had any problems with other Nissans and Infiniti...This is frustrating.

 

1st = Cat failed
2nd = F/A sensor failed, which they end up fixing it for free because they thought it was somewhat related to the cat.
3rd = F/A sensor...resetted ECU.
4th = O2 sensor failed/replaced for free.

Do I qualify for a lemon? hahaha...
