Are cheverlot impala or Malibu 2016 or newer are good reliable cars? Thanks for you advice.

NO, GM quality is poor

Any good recommendations for a good reliable 4 door car this going to be my first car.

I recommend any Honda Civic Sedan with Standard Transmission or a Toyota Corolla, they’re both reliable 4 door sedan.

Get a Toyota Corolla. They can last until you're 90 years old.

Since you're looking at a Malibu, check out the Toyota Camry and then Honda Accords.
