Is there anyone with a 2021 model and a 2.0T engine that has an engine warning light on? The 4S dealership said the fuel injector is clogged. How should this be handled?

I've been using 95 octane fuel for over 3 years now, with more than 40,000 kilometers on it.

You can only change it, over 10,000. The Highlander needs to add a cleaning agent every 10,000 kilometers and use standard 92-octane fuel, otherwise the fuel injectors can easily get clogged.
