Toyota also lousy. on the first day when i got my Vios. i drove it straight to SC after 2Km from sales office because a loud noise came out from the front wheels.
How should I to decide. So scare they will release a nasty lion for me

This goes back to your luck and some research. Every car out there has it's own set of issues. With manufacturing and design standards where they are today, this comes as no surprise. In the old days, manufacturers always strive for 100% quality. These days they're trying to strike a balance between quality and their profit margin.
My Vios had numerous problems in the past year, that I decided to replace it. In the 5 years I've had it, I had something to complain to the SC each time it was sent for service, ranging from rattling noises, absorbers that leaked twice, deformed plastics/rubber around the window, electrical problems that causes the steering to stop working and lock while you're driving, alternator that gave out, wheel bearing that gave out too, washer pump.....etc..etc...the list goes on, but I was the only one I knew who had these issues. The rest of my friends using Vios never had a single issue with their cars and they don't exactly drive their cars gently either.
You need to weigh out the pros and cons then decide what's best for you. The problems with mine are minor issues. I'm confident that any technician would be able to fix them, well, except for the vibration noise cos' that a tough one to troubleshoot since it doesn't happen all the time. I just drove out to lunch with my colleagues and no noises at all.
