Not so.
I've owned an Escort and a Tracer (same car, just a Merc) and did research before buying them.
They've been excellent, extremely reliable trouble free cars.
You bought two Mazdas, apparently.
Also, while JD Powers tends to be suspicious on their initial quality studies, their long term studies (3 year old cars) tend to be more accurate.

Notice what the top three are? Honda and Toyota.
