The squeak in the rear suspension would have to be the most prominent issue with this car. I complain about it every time I take the car to be serviced. And they claim to have "lubricated the bushes". This is no more than a temporary fix. I doubt the problem will ever be solved.
The left hand front tire keeps wearing out, I replaced it at 15000 kilometres and already need to buy a new one as the outside edge has no tread whatsoever!!
There is a rattle in the back of the car, which I have now come to accept as a permanent fixture.
When cornering right, the left hand rear wheel will sometimes squeak pretty horribly. This tends to get worse after the car has been driven for a while and everything has warmed up a bit. But because the problem is intermittent, I doubt to dealer will ever admit to it, until wheel falls off the car!
The styling of this car is incredible for what it is, much cooler than the Yaris or Swift in my opinion. The engine has a nice sound from inside the cabin. The dash board looks awesome.
In regards to the performance, for some reason this car is heavier than the Yaris, even though it is clearly smaller in dimensions. Also, don't be fooled by the quoted power of this car, as I recall it is very similar to the Yaris 1.5. I can assure you this car performs nowhere near as well as the Yaris in the real world. This car has barely enough power to keep up in modern traffic conditions. I pretty much have to floor it when the lights go green. I'm pretty sure I know why this is but won't go into detail here.
I ended up buying this car over the Suzuki Swift because the Swift is only available in 4 door, a decision which I do NOT regret. 4 doors on a hatchback is just pointless.
In regards to the stereo, I saw one review online which said that the head unit was good quality but the speakers not very good. I partially disagree with this, the speakers in the Yaris have tremendous bass, but nothing else, no highs whatsoever. The speakers in the Getz are a much better balance really, much better overall sound. Poor build quality is probably the biggest overall problem I have with this car.
