I just received an odd letter in the mail from GM concerning my 2017 Volt (see attached image).

It says something about a connector that might be recessed "back into the high voltage battery disconnect relay assembly" and the fix involves reprogramming the "hybrid powertrain control module 2".

Boy, you can tell an engineer wrote this letter! Has anyone else got this letter? Or do you understand what the heck they're saying? I plan to take it into the dealer in a week or so. There was no recall number or any identification I could find so I wonder if the dealer will just think I'm nuts!

Here's the full info from GM's recall site. Mine requires the new relay fuse and am currently waiting for the part to arrive.

GM Program #:
N162070470

Date Issued:
Aug 15, 2017

Program Title:

No Start or Loss of Propulsion - Expires 9/30/19

Program Description:

On certain 2017 model year Chevrolet Volt vehicles, the high voltage interlock connector behind the high voltage battery disconnect relay fuse block cover may be susceptible to becoming recessed back into the high voltage battery disconnect relay assembly. This may cause an electrical disconnect which could result in a loss of vehicle propulsion and/or a no start condition. The malfunction indicator lamp may be illuminated and DTC P0A0C – “high voltage system inter-lock circuit low” may be set. A “Shift To Park” message may also be displayed. Additionally, a subset of these vehicles may have a condition in which the 15A fuse in the high voltage battery disconnect relay may prematurely open. The open fuse may prevent the low voltage battery from being charged by the 14v DC power module. If this were to occur, the vehicle will provide warning to the driver and eventually lose electrical power. Once power is drained from the 12 volt battery, the vehicle may lose propulsion and will not start.

Repair Description:

Reprogram the hybrid powertrain control module 2; and if applicable, replace the 15 amp high voltage battery disconnect relay fuse.

Don't ignore this recall notice. Schedule an appointment to have the vehicle checked, repaired as soon as it is convenient. I just had this repair done, and another recall involving the dealer installing a protector on the fuel emissions line at the same time. It took under 2 hours including the dealer performing a multi-point vehicle inspection.

Do we know the date ranges affected?

I just had this along with two other recall's done to my 2017 Volt. My advice, don't overthink this, just take it in and have them take care of your Volt.

 

[JRRF]

Were these early model year 2017's?

What are the build dates of those of you that had this done. I've gotten no letter yet...

Vehicles built after July 20, 2016 (ending August 11, 2016) only receive the Programming procedure.

My 2017 Volt was built on/about 22 June 2017, and was hit last month with 3 recall's in the same month. I have a post on it with details.

Vehicles built after July 20, 2016 (ending August 11, 2016) only receive the Programming procedure.

Well, the website shows no recalls for now. Fingers crossed.

Vehicles built after July 20, 2016 (ending August 11, 2016) only receive the Programming procedure.

I don't believe this is correct. At least the letter sent for my June 6, 2016 built Volt says the hybrid powertrain control module 2 needs to be reprogrammed. Having it done on Monday.

I do not believe this is accurate. My 2017 Volt Prem was built may 15th, and I received the notice too.

Got this recall notice - and I've already had the joy? of dealing with this issue in real life.

Ordered my 2017 around march of 2016, took delivery, and at 8,000 miles had this failure exactly as described in the recall. Left me stranded on the side of a highway.

I've since put 19K on the car since they fixed it without any issues. A bit nervous to take the car in to the dealer, last time I had recall work done on my volt they returned the car with a huge gouge in the rear bumper (which they fixed admittedly) but I was in a gas sucking loaner for another 2 weeks.

If you have an early build 2017, I'd get it looked at ASAP, it's not fun getting stuck somewhere and waiting 1+ hour for a tow.

I had this recall performed last week. I'm in the habit of checking the recall section of the MyChevrolet app every few weeks while waiting for it to refresh my charge status. Noticed it there and made a mental note. A few days later my dealer proactively called me to set up an appointment. I got the letter in the mail a few days after work was already completed. I'm pretty happy with how easy it is, for me anyway, to learn about recalls and get them taken care of.

There is only one Volt tech at my small dealer, but he was proactive and wanted to replace the fuse relay in question even though it did not appear to have shifted. Maybe some motivation was their ability to charge more labor back to GM. Either way I'm happy. Three recalls in one year of ownership but nothing too serious. (a previous software update and the leaky oil pan) Probably more bugs than the average car, but I'm glad they're finding and fixing them. Could be worse, like the Pacifica PHEV's that were all recalled for potential battery fires, leaving their owners with nothing.

I called my dealer several weeks ago to see if any of the "recalls" under discussion for 2017 Volts applied to me, and was told that there were three applicable, but that parts needed to be ordered to do all the work. They said that they'd call me when the parts came in. I got a GM letter last week formally announcing the three recall items, and I was scheduled to come in for the work this past Tuesday, but they called to tell me that one part (a fuse) was still on backorder. Still waiting for a call!

Alright guys. Today, Sat, Sep 16, I took the VOLT in for that notice about the electrical connection that can become recessed and will shut down the car. I made the mistake to have called it a “RECALL NOTICE”. The Service Writer quickly told me it was not a Recall Notice. It was an informational memo to owners about the possibility of a problem if that icon comes up on screen and an extention of warrentee. He said that you only would bring your car in if you have that icon show up on the dash.

I also brought up the non working charge port light which they said they would “look at”.

The job was supposed to take 2 hours and I was going to wait for the car repair to be completed.
I was in the waiting area about 20 minutes when the service writer came in and told me that I did indeed have a recall for the electrical issue and there was ANOTHER recall on the car.

The work Times needed have exceeded 2 hours, the recalls won’t be completed until MONDAY and not sure about the charge port work completion time.

I don’t know guys. I looked around and there were NO Volts, but I did see 2 BOLTs in the yard. TOP this with this thought…. My volt is over a year old and it is now burning the fuel so I only run with the engine right now. I asked the service writer how long this will be before the battery power is used for the main power again. He didn’t know. He didn’t know the car automatically changes to the motor to burn out the old gas. Rather, his comment was that it was my choice if I wanted to burn gas or run on battery. We all know this is not the case. But he didn’t????

So in my humble opinion, if you have this notice, take the car in. If what they are warning you about actually happens, you can be stranded somewhere.

I hope this service writers knowledge on the VOLT is not an indication of where GM actually stands on electric cars.

Was your car listed on GM's website has being subject to the recall?

In the automotive world, those that know about cars and are mechanically inclined become mechanics. Those that don't and aren't become salesmen. If they can't sell, they become service writers.

Update: I called to check on the backorder yesterday and was told that the fuse was expected next Tuesday. I expressed my disappointment and concern that the power could fail and leave me stuck on the roadside out in the wilderness. Shortly after that, I got an email from the dealership offering me a loaner while waiting for the part. Remarkable!

Received notification N162070470 as well. Brought my 2017 Volt (made February 2016) into an alternate Chevy Dealer as there has been a new car dealer mechanics strike in the Chicago area for the last 7 weeks. They did perform the reprogram of the hybrid powertrain control module 2 (HPCM2) but did not replace the 15A fuse. The dealer claims that the 15A fuse is only replaced if open (defective) and is not replace as a preventative measure.

Here is a link to the procedure:
https://gm.oemdtc.com/7895/16185-cu...art-or-loss-of-propulsion-2017-chevrolet-volt

The procedure implies that the 15A fuse is to be replaced on 2017 volts from beginning of production through July 20, 2016. There is a smaller window July 20, 2016 to August 11, 2016 where only HPCM2 reprograming is done.

I asked the Service Rep from the dealership I bought the car from (they settled their strike just yesterday) about the 15A fuse issue and he essentially backs up what the alternate dealer stated claiming that the 15A fuse is only changed out on a case by case basis and will not be changed out unless open (defective).

Has anyone else run into this issue?

It appears that most in this forum are getting the fuse replacement up to the July 20, 2016 date.
