I think it would be very foolish to believe that there is a car maker who cannot make lemons. Or at least make all their cars almost perfect. Even some things like the tinting, tow bar, etc are installed locally and it could be a source for issues too (eg. Rocket's post). Also, my friend bought a new Mazda RX-8 three months ago. He has had to return it 4 times to get the tinting fixed. Also it is getting a new gearbox this week because that failed. A new gearbox after three months only... So whilst we may have had some issues, you may or may not be so lucky. This will be so with any car maker. But I can understand your intrepidation, You would expect them to get things right for the amount of money you're paying. You're not buying a $200 power drill, you're buying a $70,000+ car.

In the case of getting a lemon or poor customer service, I would expect to be properly compensated. Especially if they expect any kind of brand loyalty.
