I've seen GM parts engineered to fail after 10 years.
IE. Throttle bodies with internal wires. The insulation hardens and cracks, and eventually the bare wires start touching each other shorting out the TB.
New TB is about $400.
I call them engineered to fail because I'm sure they could make the wire insulation last forever if they wanted. However that means no replacement parts are made or sold.
I'm sure there are plenty of other misc parts engineered to fail. Spark plug coil packs are another example. It seems every manufacturer needs the coil packs changed every 100,000 miles or so.
