I have a gen 2 and a gen 3 Prius - Do you guys like the newer ones better? Thanks.

gen 4 owners are mostly very happy, although some were burned in the early years by the exhaust recirc coolant heater leak, to the tune of a new cat, or even a blown engine.gen 5 is too new for reliability data. owners seem mostly very happy aside from minor complaints.
current prius owners who haven't moved to gen 5 usually sight the cramped cabin, and smaller hatch space, as well as lackluster mpg improvement.
but it has brought in new prius buyers who have been waiting a long time for a sportier, better looking model.

 

Well....FWIW......We (wife & I) are on our fifth Prius (Gen 5)......a Gen 2 (2005), two Gen 3 (both 2010) .....a Gen 4 (2017) & now a Gen 5 (2024)......the Gen 2 had 150,000 mi with no problems other than it had started to burn some oil, nice car ......the Gen 3's had 120,000 & 130,000 mi with no problems, nice cars ......the Gen 4 has 110,000 mi with no problems, (we still have it) a VERY nice car .....the Gen 5 has 8000 mi with no problems, nice car ......all purchased new ......to sum it all/up ......I wish I could have purchased another NEW Gen 4 .....I would be hard/pressed to find anything I don't like about this car! ......again, FWIW
