Firmware update 2014 plug in prius hybrid

congrats and welcome!
i don't think so. you can contact a dealer about possible updates, and maybe there is info at toyota.com/owners, where you can input your vin and see maintenance history, recalls, updates, tsb,s and etc.
how many miles on her?

 

If you’re looking for apps like spotify, your best bet is to just install an aftermarket android radio.

More on EGR cleaning in first two links in my signature. If you’re on a phone, turn it landscape to see signature.

It’s a little nuts, but regardless of question 3rd gen Prius owners are asking, it’s become opportune time to warn them of the probable demise of their 3rd generation engine, due to it’s Achilles heel. It’s somewhat akin to “Oh by the way, have you had a shingles vaccine?”

3rd gen Prius introduced a new Exhaust Gas Recirculation system, which has proven very prone to clog up with carbon, very “reliably”, somewhere between 100k and 150k, and just as reliably the engine head gaskets are failing (disastrous and expensive).

Toyota has pretty much turned into the 3 uncommunicative monkeys on the subject. Also, there’s much debate here regarding the correlation between EGR clogging and head gasket failure.

Anyway, warring camps aside my 2 cents: look into it. And if possible avoid dealerships; they’re a hopeless/expensive rabbit hole on the subject. Often, and sadly, DIY is the shortest distance between two points.

Depending on your location there may be professional options. Tampa Hybrids in Florida, and Hybrid Pit Stop (LA) are two options known here. Which is pretty dismal I know. There may be some local-to-you PriusChat member that can help too.

70k is pretty much ideal time to get on this, btw.

Also, if a fair percentage of your miles are electric-only (with the plug-in), it may forestall the EGR clogging. That said, @bisco’s scenario is just that, his miles are modestly more (90k~?), he’s getting engine running rough symptoms, and is currently trading it in AFAIK.
