Jeep just had an OTA update cause the car to shut down on the highway (it is rumored).

Before we put computers in cars, we had the myriad small things that would break (stuck doors, stuck windows, failed seals, leaking gaskets), a continuous stream of recalls for low-probability safety issues, and the occasional Gremlin or Pinto.

My favorite example is the Hyundai Elantra. They changed the alloy used in one of the parts in the undercarriage. Tested that model to death for a year, as they do, but their proving ground is in the southern United States.

Several winters later, it turns out that road salt attacks the hell out of that alloy and people have wheels flying off their cars in the middle of the road.
