Cars that don't work for stupid reasons
Hal 9000 is on the mark with cars that fail due to bad earth connections. BMW 3 series had faults in door actuators, could not unlock remotely, could only get front windows down and sunroof open, while parked in the rain! Crawled in thru front windows, car would not start, windows would not close, door would not unlock even with inside handle. Finally got key stored in remote control to open doors with the one key slot on the car on the drivers side. Dealer had not explaination on why this happened, other than "actuator" failures. This is a case of electronics getting in the way of using your car normally, with little operator override capability.
