Just hit 100,000 on my 07 Vibe with the 1.8L and never a single problem.
Easy to perform maintenance on. Great MPG's in my view,
27-28 city 33-34 highway, not so bad. These are known to have very reliable auto transmissions and the 1ZZFE is a proven engine.
Keeping this car until 200,000 miles, and I feel confident it will get there with no problems.
All I have done is spark plugs, tires, coolant flush, drain and fill on transmission, and a serpentine belt.
Only negative thing is that when I got new tires I found out the rear alignment cannot be adjusted without installing shims. So the alignment cost around 300 bucks.
