2024 ACURA TLX Engine Problems

I understand Honda isn't doing soo well so I hope this is added to the list of the feds research we just bought this tlx aspec don't understand how these cars need to be 4000lbs but anyway the gas mileage advertised is not what you get I've seen on multiple forms people are saying they experience 13 mpg and on a cylinder engine that is just not acceptable 2 hear grinding noises in our drive train that the dealership doesn't hear unless it shows up in a scan tool 3 the engine has very loud valve tapping sound the tail tips have alot of black soot on them also evident of too lean gas mixture 200 dollars in gas in 8 days of owning this NEW car the transmission also has a mind of its own in sport mode reving the motor to 2 and 3k rpm all by itself...
