Just received a message of "Reduced Engine Power" visit your dealer. There are no codes and I do not notice any reduction of power to the vehicle while driving. Battery and alternator checked out ok. Unhooked the battery and the codes came back immediately. Any ideas of what it could be and where I should start looking? It is a 2019 Lexus NX 300 F-Sport with 79k miles.  Thanks

There are no codes

There have to be. You just need to use a better scanner.

you can't erase codes or do a reset this way anymore with modern computers in cars.
