2020 Nissan AltimaRecalls, problems, MPG & safety

“I currently own a 2020 Nissan Altima with 49,186 miles and I am reporting a recurring power door lock failure. This vehicle was inspected at the Nissan of Cumming location this morning to confirm the issue. Three of the passenger-side door lock actuators have failed within a short period of time. The two rear door locks stopped working at the same time, and approximately two weeks later the front passenger door lock also stopped working. The driver's door has started to not unlock when turning the car off where it normally did up until recently.

The claim was submitted to Nissan corporate warranty/Powertrain Call Center (PCC). Basis of Complaint (Recall Non-Compliance): Nissan North America and the dealership have officially declined the zero-cost recall remedy mandated by federal law, demanding nearly $10,000 for an engine replacement. Nissan claims the engine failed due to "loss of compression" rather than bearing…”
