I hear what your saying but they were cheap cars and neither was a "Halo" car.This is not a lot of failures, you're just hearing about every little thing...given the numbers, miles, and what these are...we're doing well.
Seriously, take everything in the context of the bigger picture. There will be failures, breakdowns, etc...that's why you get a warranty with a car. A sensor failure...you know how many oxygen sensors I used to replace on my Trans Am and IROCs??? Geez those cars would throw codes like lottery numbers.
