Hello. Owned a 2014 Yaris LE 4 dr Hatchback (bought new in Nov 2013). I chose it because I wanted a 6 feet tall person to be able to sit in the rear seat with zero issues - the 4 door Yaris Hatchback allows this. I am 6 feet tall myself and with the driver’s chair set for me, I could sit in the rear passenger seat directly behind the driver’s chair with room to spare between my knees and the chair’s back.
Drove it for 110,000 km and just traded it in for a 2019 Rav4. While I owned it, I used only one brand of synthetic oil and oil filter. Never took it in for dealer servicing, and it ran fine without problems for the almost 6 years that I owned it. Drove it over the Mountain range by myself, it had lots of power (to my surprise) but when I did one of those drives with family and dog, and the car loaded from stem to stern, it did require a bit more effort up hill for sure.
Averaged 8.2 km per 100 km driving 70% hwy 30% city using 87 octane. Used seafoam additive once a year to keep injectors clean. With winter tires, it drove well in the snow and made it up every hill (I live in town with steep hills. Even with the winter tires in it’s 3rd season of use, it handled well. Never got stuck.
Mine was a great experience. Hope this helps.
