I finally got to try ACC recently when my car was in the shop. They gave me an '18 (I think) with ACC. It was interesting but scared the crap out of me when I tried it. I set it to 65 on the highway. Was working fine until I got to a curve where the speed limit dropped to 35 (for good reason). The Volt sped up and took the curve at 65 
No thanks...

You're using the Adaptive Cruise Control for the wrong application. Ha ha ha! And you know what? It won't read stop signs and traffic lights either!I finally got to try ACC recently when my car was in the shop. They gave me an '18 (I think) with ACC.

The ACC isn't recommended during heavy rains, snow, tight curves and winding downhill roads. It is excellent on Freeways on long distance driving. It won't see stopped cars, pedestrians, squirrels and raccoons on the middle of the road, although your collision system will go off.
"Most cars, including the Volt, that uses the adaptive cruise control, uses the millimeter wave radar mounted behind the bowtie (Chevy Volt) to detect how close you are to another car and either applies the brakes or the accelerator. So it sees the wrong distance of another car on another lane on tight curves. Radar isn't very good at "seeing" stopped cars and so it also uses the forward collision camera to prevent you from hitting cars that suddenly stop. GM chose to use almost all the same parts as Tesla uses for their system. (Bosch iBooster for the brakes, Bosch radar and I suspect a lower end Mobileye camera)" - from a post in Reddit.

LOL I know. I was just caught off guard because when I approached the curve, the person in front of me slowed down so the Volt slowed down (which was good). That person then changed lanes and the Volt (I guess not seeing anyone in front of me) resumed to the preset cruise speed which surprised me a little bit (actually a lot
)Yeah, curves are problematic. In addition to needing to slow on curves, ACC can mess up if the car in front of you takes the curve and the ACC system, pointed in the direction you're going but not in the direction you will go, thinks it has changed lanes and speeds up.LOL I know.

It's not possible because there are large parts of the body of the car that are significantly different between ACC and non-ACC Volts because of all the sensors and electronics required. Plus, the control electronics are usually tied to a particular VIN and probably won't work with a non-ACC VIN.
Of course it is possible. People have certainly done bigger and bolder. It however may be cheaper and easier to trade in the current car.

So:
1. Buy a salvage car with ACC.
2. Take all the non-ACC bits from your current car and fix the salvaged car.
3. Hope it won’t kill you.
4. Pay for two non-functional cars.
Sounds like a plan. Good luck!

·I am reliably told that ACC cannot be added after the car leaves the factory.

·If you had both a donor car, a car without ACC, and a dealer / factory scan tool it could be done. The last piece is likely the hardest to get for an owner.
In addition to the different modules, it's possible the ABS system or brake booster are different too.

I just purchased a 2018 Volt premier with the adaptive cruise. Driver confidence package 1 and 2 were a requirement to add ACC. So I guess if you're looking to add it after the fact, you probably have to add those too because it probably requires all the sensors that come with them
brawas,
I recently purchased a 2017 Premier that has driver confidence package 1 and 2. I'm bummed to find out later that it does not have ACC and was looking forward to using it (my Ford Fusion has ACC). Has anyone successfully added it to a car like mine? Sounds like a major technical challenge and maybe voids the 8 year 100 k warranty? Does anybody know answers to these questions? Has this ever been done?
