Talk to the dealer and tell them about that TSB. It's not a software update. I'll post the gist of it for you.

drdiesel1 you are my freakin' hero. I called Chevrolet Customer Assistance today and had them re-open my case. (As you may recall from the original post, I last left off with them parroting my dealer's utterly preposterous "Vehicle is operating as designed" determination, with them refusing to follow up or even consider the measurements I'd taken.) They have now updated my file and will have someone contact me tomorrow with the next steps.

While I'm not entirely shocked (shocked, I say!) that my local dealer missed this TSB, the fact that the "specialists" (and their manager) at headquarters were utterly incapable of connecting the dots back to such an obvious service bulletin just makes me want to face-palm from the rooftops.

Oh well, hopefully this is the turning point. I'll post as soon as I have something new to report...

Glad to be able to help! It's my job and as an owner, I keep up as much as possible with this car. I'm a Chevy dealer tech
and I fix the stuff others can't :mrgreen:

As far as my dealer is concerned, the heater is heating just fine and the A/C is cooling just dandy, so it is the assessment of their "factory-trained technician" that everything is working as designed. They kept my car for three days before arriving at this conclusion, so at least they were good and thorough about putting the system through their prescribed tests.


They kept your car for three days but probably spent about three minutes actually "working" on your car. Time to find another dealership.

Wow, for any dealer to figure this out all by themselves they have to actually be able to read? Amazing!

I've heard so many complaints about dealers not being able to diagnose "known problems" like this that I kind of wonder if GM's information systems are to blame. It seems to me that a dealer's service department should be able to do a search for symptoms against GM's database of service bulletins to easily find the cause of these problems. The frequency with which the dealers aren't solving these suggests to me that maybe they can't or that perhaps the search engine or the bulletins' keywords aren't up to snuff. Or, heaven forbid, that all they have is a list of TSBs that they have to scroll through looking for something that seems applicable.

Pretty much, if you want as much info as possible. It will narrow down with key words, but it's still a matter of time to search for them.
They don't pay us to research anything. We get 3 tenths of an hour to find out what's going on. That's it!

After speaking to Chevrolet Customer Assistance on Friday, and phoning the dealer Monday afternoon, I finally got a call back today. My dealer's "Customer Experience Manger" said that the tech didn't apply this TSB the first time I took my Bolt in because it was not reporting certain DTCs required by the bulletin. (I wasn't going to argue, but that's a very creative interpretation of the phrase "may find one or more DTCs set".) She also claims that this bulletin calls for both a hardware AND software ("reprogramming") fix. Should I be worried?

In any case, they have agreed to perform the work and I have an appointment tomorrow. I will continue to follow up as things unfold...
