It depends entirely on the degree to which the neurons are modified or artificial. If you replace some parts of a care with ones made out of chewing gum or ice, they may work for a while under particular conditions, temperatures, etc. Think of how simple an artificial heart is by comparison to even a single neuron, let alone a brain. It's a pump with a regular beat. Yet, the longest anyone has survived with one is seven years.
All I'm saying is that for something to function identically to a neuron, it must in all likelihood be a living organism, and to be a living organism, it's likely that it needs to be composed of complex organic molecules. Not due to the specific magic of organic configurations but due to the extraordinary level of fidelity required to reproduce the tangible feelings produced by living organisms, and the critical role those feelings likely play in the aggregation of what we consider to be consciousness. Consciousness is made of feelings themselves, and their behaviors, their internal consistency and not just the neurological behaviors which are associated with them. It is a first person experience, completely undetectable in third person. Or, to use your car analogy, would the replaceable parts of a car include a driver? Are all drivers capable of driving the car in the same way? A blind person can physically drive the car, push the pedals, turn the wheel. Can a blind or unconscious nucleus drive a neuron?
