Adaptive Cruise Control Problems

[greyno02]

Rolling down I95 at 70 plus with Adaptive CC engaged at the lowest sensitivity setting when all by itself my Genny engages the brakes (smoothly thank God), the speedo goes to zero and stays there, red SSC disengage warning, auto hold warning, check engine, ABS warning, EPB warning come on and stay on until I shut the car down in my garage. The next morning when I start the car up it still has all the lights on and speedo still on zero. It stays that way all the way to the dealership.

They've had the car for almost a week now. And I am not encouraged by their explanations (or lack thereof) as to why they can't fix it.

Any guidance on when I should start raising hell??

sounds like computer went bad. Do you have any modifications to your car?

None. Straight stock at this point. The dealership is telling me now that they have tested or ruled out 26 of 30 modules. something about a serial can bus etc. They are definitely stumped by this one. Talking about bringing in a field engineer.

Not saying htis is your problem but a few years back my suburban had similar problem and it turned out to be bad connectors where wires pluged into the computer.
