NHTSA Complaint #11423535 — 2017 NISSAN ALTIMA

1).Sometimes I can smell exhaust gas inside the car room like in my previous car Nissan Maxima SE 2008, which is extremely dangerous. 2).The rear camera works no so well - sometimes rearview disappearing completely. Also, approximately a year ago, I received a letter regarding Nissan Altima SV 2017 recall(s). I contacted several different Nissan dealers in Miami but nobody knows about the recall. Could you explain please what is going on with recalls? Thanks.
