jacko - Last time I checked, I never heard of a car that has been "trouble-free"
, they all have their own problems be it electrical, HVAC, trim, transmission, sludge, brakes, etc.
Every make has a problem. Building a "trouble-free" car (which I'm sure they could likely do) would simply put the car companies and mechanics out of business.
Sorry to hear about your own personal experience with this brand.
Regarding service intervals, I agree with you. I personally follow the "severe service schedule" as in the car goes in every 3 months/5000km (whichever comes first or is closer) and change the oil and have the mechanic give it a general inspection and replace what's needed.
My automatic transmission fluid is "filled for life" but I don't buy that and neither does my mechanic. He said you should change the fluid and filter at every 80,000km. A $200 job is much cheaper than a new transmission.
Bottom line, my best advice is to follow the severe service schedule. I don't wait for the service light or change engine oil lights to come on. I get it done much earlier.
