Better not buy any car then considering the amount of electronics they contain. An average new car will already have 10 or more computers all networked together. Cars also have more than one network as they will separate the high speed powertrain network (needed to allow for fast communication between the engine, transmission and ABS for features like stability and traction control) from all the other modules in the car.
Modern vehicles are far more complex than they were even 10-15 years ago. Usually when something becomes more complex reliability goes down. Yet despite modern vehicles becoming more complex they are still more reliable than the junkers from, say, the 80's (which were quite simple in comparison).
I grew up around the auto industry. My dad was in the business for over 40 years.
When a third-party gets his device written into the specs of a car, he not only sells original equipment but replacement equipment. So, if Chevy plans on selling 500 cars they might order 700 devices - with 200 as spare/replacement parts.
For the US military it's even better -- with up to a 4 to 1 ratio of replacement parts to original parts.
Dad's company made brakes that were used to steer tanks, among other things.
