Could accelerating rapidly and then decelerating rapidly cause any of these modules/systems to overload and fail?
Essentially the problems started when I had to accelerate very hard and then lift off quickly and apply considerable brake force. I was in L when all this happened.
But the issues didn't start until about 5-10 minutes after.
Could is a difficult question to answer, because failure modes can be very complex, especially since I wasn't part of the design team and don't know it well.
But, that is well within expected operation, it SHOULD NOT have caused any problem (even if it did). Should not, as in warranty covers it very clearly with zero liability on your part. Should not, as in the law requires it to be able to operate repeatedly and for any designated minimum maintenance interval under those types of conditions for the vehicle to be sold.
When you exceed the maximum allowed regen braking, you go into hydraulic braking for all additional, but at most all you did was push an already faulty component past that breaking point.
Again, don't feel like you did it at all, this is absolutely and without question something that should be covered in any vehicle design. There are many regulations and SAE standards regarding braking performance and range of operation that Chevy is required by law to meet and hold liability for. Whatever you do, do NOT take liability, express a sense of liability, or allow a service person to assign to you liability for this failure. It may or may not happen at some point in getting this addressed, since this failure should be reported to Chevy engineering support for evaluation (who will not want to express liability on Chevy's part). They'll probably want to pull your entire blended braking system for engineering evaluation, if they do not find visible or detectable problems. This means of course that they'll also need to put in a completely new unit. If they start to harass you and try to assign liability to you, I'd consult a lawyer... but it rarely comes to that. You have the recent recalls on your side in this, they will likely bend over backwards to fix this thoroughly and quietly.
I hope it goes quickly and painlessly, either way!
