I had same problem with mine after the first recall was done. They replaced number 2 nox sensor and told me there is no way the recall could affect the number 2 sensor. I paid over 800 bucks out of my pocket and the service manager told me it’s likely going to be reimbursed when the fix comes out. I went ahead with the repair. Less then 500 miles later it came on with the same code. I was furious. This time to fix it they removed the update and programmed back to the original programming. I haven’t been back to the dealer since and there is no way they are putting the new program into my car after the previous issues. Over 15k miles driven since no problems.
