“Propulsion Power is Reduced” DTC P0A7F PIC6203 Customer Satisfaction Campaign #16055

Just got this message on my.chevrolet.com

GM Program #:
N162048200
Date Issued:
Oct 06, 2016
Program Title:

Reduced Propulsion Power

Program Description:

Certain 2016 and 2017 model year Chevrolet Volt vehicles, equipped with an automatic transmission (RPO MKV), may exhibit a condition where the driver notices a “Propulsion Power is Reduced” message in the driver information center. This condition is sometimes accompanied by the diagnostic trouble code P0A7F or a significant decrease in actual electric vehicle range. The driver may also notice the engine running at consistently higher power than normal to propel the vehicle and acceleration is slower than expected.

Repair Description:

Dealers are to reprogram the hybrid powertrain control module 2.

Funny enough I had my 17 at the dealer in order to fix an annoying wind sound past 35mph(which they were unable to fix as it only occurs occasionally ugh) but according to the service guy as the campaign just started that day they were unable to apply it to my car...I guess i'll go to another dealership in a couple of weeks to apply this fix and to see if they can fix the wind noise.

Anyway, has anyone had the above happen to them?

There is a new recall 16055 that just came out today, had to program 4 in stock cars already. The wind noise I have not come across yet.

Since May there's been an engineering bulletin PIC6203 on this issue, intermittently affecting SOME Gen2 Volts.
Specifically a “Propulsion Power is Reduced” message possibly combined with the DTC P0A7F

However it appears they have finally identified the root cause was an HPCM2 software issue and have issued an update via a Customer Satisfaction Campaign 16055

It appears notification has been initiated on the MyChevrolet app, as well emails/letters informing affected owners has commenced but since it was only released on Dec 5, they may not have reached out to everyone just yet.
Some dealers may even be proactive and either email or even call owners of affected cars in which they have sold.

If you wish to know if this campaign 16055 applies to your Gen2 Volt you can call your dealer or Volt advisors at (877) 486-5846 with your VIN and they can check it in the Global Warranty system.

I'm trying to decide if I want to have this done tomorrow or not. I haven't gotten to drive my car for over 2 weeks because of the HV battery issue that affected me, and I'm not sure how long the recall will take. I'd really like to have my car back...

Reprogramming HPCM2 will only take about 1/2 an hour once the car is actually in the service bay and the critical connections made.

The dealer is supposed to call me to give me an exact ETA tomorrow around noon (after the part they're waiting on should get in) so I'll ask if they can do the recall then. That way it'll already be in the service bay.

Right. But since not all owners use the app there will be a sort of "blast" occurring including emails, dealer phone calls, and even letters via snail mail.

These are normal actions when updates like this have been initiated by a "Customer Satisfaction Campaign"

So this fix takes care of the dreaded "shift to park" failure? Great!

It's showing in my App, as well. I just emailed my local (CANADIAN) dealer to see if there was any further clarity on the subject.

You don't need to wait for the app. You can call your dealer at any time, give your VIN and they will see if there are any recalls, service campaign, etc.

From the looks of it, seems ALL Gen 2 Volts up to a certain build date are affected by this recall. Someone reported having a Aug '16 build date and NOT having this recall pushed to them. My '17 was built in March and got snagged in this recall.

Mine was June 6th 2016 and was recalled.
