Can the RAV4 PHEV engine develop problems if it’s rarely used?
I’m thinking about buying a 2026 RAV4 PHEV and have a question about the petrol engine.
My daily commute is around 50 km, which is within the EV range. I also have solar and a home battery, so charging is basically free for most of the year (I’m in Australia).
A few times a year (2-4 trips), we do 900-1,000 km road trips. Charging outside the major cities isn’t great, and I don’t want to plan trips around chargers, which is why I’m choosing a PHEV instead of a full EV. This will also be our family’s only car.
My concern is that about 95% of my driving will be in EV mode. I’ve heard engines can develop problems if they aren’t used for long periods. I know Toyota recommends using at least one full tank of fuel each year.
Has anyone used their RAV4 PHEV mostly in EV mode for a long time? Does the engine look after itself, or is this something I should be worried about?
