NHTSA Complaint #11533952 — 2013 NISSAN ALTIMA

Steady Check Engine light came on April 25, 2023. Just had oil change/filter done day before. Had tune-up done May 25, 2023. Had mechanic who replaced my catalytic converter and (2) O2 sensors a year ago check my car. Found that the inside of the catalytic converter was melted. They checked for a fuel leak in engine, none found. Replaced catalytic converter and front O2 sensor. As of today, no Steady Check Engine light has come back on. I think a Flashing Check Engine light should have displayed for something as serious as a fuel leak. What if my car caught fire while driving? Also, I was told several years ago by a local Nissan dealer that my driver side airbag would need replacing - that indicator light never came back on the dash board either. Faulty sensors? I notified Nissan in TN by mail.
