Engine was sluggish and leaking slightly when I first purchased it. Had to do a full tune-up, clean the injectors, rinse the fuel tank, change all fluids & filters, and replace the gaskets.
Front doors' latches couldn't detect if either door is open. Integrated latch assembly means a lengthy ordering time and expensive work. Had an experienced electrical mechanic to open their housings and fix the internals.
Shrieking noise from below the car which was concluded to be a normal over-revving symptom by a Toyota mechanic. Had the car checked by an exhaust specialist and turned out to be a clogged catalytic converter (due to inconsistent fuel quality in Indonesia). Replaced it with a free-flow spool (greater emissions, but more power & overall Km/Lt).
Air-con motors within the dash make whirring noises every now and then. This problem is still present as no one has come up with a convincing solution.
Clunking noises from the front suspension or steering assemblies during slow & inclined cornering. No one could determine the cause.
Squeaks from the rear hatch area and rear seat bolts. Rectified the latter but not the former which is still untraceable.
In my quest for better comfort and space, I replaced my Suzuki Swift with this used Toyota Harrier. I've fulfilled my goals, but am now concerned with its questionable long-term quality. Being a grey-import doesn't help with parts availability either (although most fast moving parts are relatively easier to find, since those are common with Camry's).
Power is good, fuel consumption is acceptable for what it is (3 liter SUV) and the ride is pleasant. Space is abundant. Bonus for the "Four" / 4WD model is the ample grip on wet roads. Naturally, fuel consumption is slightly worse compared to the FWD model.
Its looks have aged somewhat when compared to the newer generation Harrier's but this has been helped a lot with the addition of aftermarket lights and 20" wheels.
I've been keeping up with repairing its minor faults, with many DIYs but don't know whether I'd still have the patience to do so after a couple of years. So I hope this car can behave well from now on, since I'd like to keep it for quite some time. Otherwise, I'm replacing it with something more reliable.
