I've had my 2010 since 2012 and 53,000 miles. It now has 242,000. Not so long ago I replaced the intake manifold, EGR valve and cleaned out the EGR cooler to be like new. Things were fine for a while. Well, it's doing the shimmy and rattle at start up again and occasionally shuttering under light acceleration. Hope it's not the tranny. I'll probably pull the EGR off and take a gander at it, but it has less than 10,000 miles on it, who knows. Anyways, I am considering looking at something in the 2020 range. Is there anyone who knows which of the newer generations are the least problematic? Or, maybe better said, as reliable and long lasting as my 2010? Also, I need the same amount of space with the rear seats down which seems to eliminate the newest generations from consideration. Any help or direction would be appreciated. Thanks,
Are you loosing engine coolant? Kinda sounds like the head gasket has failed. It's extremely unlikely the transmission is bad. The Gen 4 has less issues.... So I've heard anyways. Depends on who you chat/talk with. And what you believe.
The latest thing is using the detuned Camry engine an MA or AM . Timing chain engine from Camry detuned for Prius duty . Once they regularly start pegging over 200,000 I'll be looking at until not so much . The power plant has to prove itself for me to buy it and then the interior and chassis are welp cheap not to. Keep type stuff.
What are you talking about when you say "engine from Camry detuned for Prius duty"? The latest dual injection 2.5L used in Camry and Rav4 hybrids? Into a Prius?
Coolant is still in the reservoir. I guess the 2010 was notorious for head gaskets. I've never replaced it.
It doesn't take much. Using a bore scope in cylinders 1 and 2 with pressure on the cooling system might show coolant leaking into the cylinders. 387,000 plus miles on my 2010. I replaced the head gasket at 301,000 miles....
We have two Gen 4's, 2017 and 2021 and both have been boring for this DIYer! (I have to rely on our 2008's to get to do any of the fun stuff.) Seriously, though, don't limit your search to the Prius....the Corolla and Camry Hybrids are, also, excellent! And even a late-model Avalon Hybrid. (My co-worker has one....rides as smooth as a Lexus!)
