Loss of power

Thank you for reaching out to Car Genius. There are plenty of issues that can come about that don't initially trigger a check engine light. I could recommend checking regular maint. type items, like air filter and a fuel additive. But a shop should check this out and read the live data from the vehicle at the time of a power loss to help nail down the exact cause. Thanks again for reaching out to Car Genius. Here is a list of certified shops near you. https://repairpal.com/nissan-repair-near-me?zipCode=20737&vehicleId=78613 . -Austin
