................................................In general, I've found that the recalls were done as sloppily as they thought they could get away with.
When I bought my first Fiero in 93, I soon learned of the recalls. I took it in to have the engine fire and brake recalls performed. I don't know what they did on the brakes, but later, when I was doing an oil change, I didn't see any heat shield that I'd read about.
I was talking with a relative in Nashville that worked for a Cadillac dealer. He mailed the heat shield TSB to me and sure enough the shields weren't there on the engine. Only the decklid strip had been removed. I took the car back and when I got it back, shields had been installed.
When driving, I kept hearing a metallic rattle. One day, I was into the engine compartment and found that the front manifold shield had not been properly installed. It was just hung over the top of the exhaust manifold, rather than bolting it in. Other shields had been modified so that they could be installed, though improperly installed.
At that time, they also lifted the car, using a floor jack underneath the oil pan. It left a very identifiable pattern in the indentation. It didn't affect the runability, and of course the dealer denied any responsibility.
