So I just had my 2012 Volt at the dealer due to a "Service High Voltage Charging System" Error message, and I have to say i'm rather disappointed with the dealer and Chevy. First the car is at 90,006 Miles, and this is the second time in a year that the error appeared.

First the dealer issue, Upon dropping the car off, they informed me that they will call when they know what is wrong with the car. I informed them about the voltec warranty, and all was well. Later that day they call me and state that the solution was reprogramming and remove the battery drain plug, and that the warranty wont cover the repair that will take 2.7 Hours. I told them to hold off on the repair, after some "ahhh's and well's on their end, I asked if they could hold off or was the work already done. They replied with "Well we kind of went ahead and did the work, you know since the computer was already plugged in", "We really should have called you first".

So anyway I paid the bill and informed them I will be placing a call to Chevy about the warranty issue.

As far as the warranty goes. The Car threw codes PIE00, P0AA6, and PIEFF. It also lists system isolation and coolant level fault. The coolant level was fine and no moisture was in the battery case, so all that was done was to reprogram HPCM2 and BECM.
When I originally called GM, they stated that it was covered under voltec, and that they will find out what the issue was. A few days later they called back with "This issue is not covered under warranty, because your volt isn't a hybrid model". I told them I was lost and asked them to clarify. They said they have several different models of volts and if mine was a "Hybrid" model then yes it would be covered under warranty, but after checking the vin they see that it isn't a "Hybrid" model so its not covered. To humor them, I asked them how to tell the difference and they stated "If your volt is a Hybrid it would be on the left side of the car right under the VOLT Emblem"

Funny thing is my original window sticker clearly states "Plug-In Hybrid Vehicle"

Call me crazy but last I knew Chevy only had one model Volt in 2012.

Anyone else run into these issues with Chevy?

Have them look up a p/n for a hybrid emblem for a Volt. Pretty sure they don't even exist. Sounds to me like you're going to have to go above to a supervisor.

Could be the coolant sensor. They are known to be flaky. Search "WOT Sensor". I replaced my OEM coolant sensor with the WOT Sensor for $25. Now, there is no way for false coolant level alerts from the sensor. Some people have been plagued by this 2-3 times, always requiring a dealer visit. Maybe yours is something unrelated, maybe not. But it's just a matter of time before the OEM sensor goes...

Something sounds fishy here. All volts are technically plug-in hybrid electric vehicles. Hybrid cars have batteries and internal combustion engines. For someone to state that your volt is not a hybrid is so wrong on many counts. If it were me, I'd threaten to lawyer up as I've always wanted to own a car dealership and service department.

I'm sorry, but I could not stop laughing at this one. If I was told that the Volt was not a hybrid by someone at Chevy I would have been on the floor laughing out loud so hard my sides would be sore. Once I got done I would have asked for a supervisor because the person on the other end of the phone is strictly reading from a script and has no idea what they are doing.

The idea that your Volt is not a hybrid for the purposes of the Voltec warranty coverage is perfectly ridiculous. It is very encouraging that they said it would be covered if it were a hybrid. Get them to tell that to the dealership and then challenge the dealership to show you, in person, how your car is not a hybrid.

Your problem does sound similar to the WOT sensor issue mentioned above. In those cases, it is true that some owners have been covered and some have definitely been denied coverage. If I were you, one of my top priorities would be to get the WOT bypass and install it so you don't have this problem a 3rd time. You might have an intermittent sensor, and if so, it is just a matter of time.

And keep working on GM until you talk to someone who is not obviously stupid. You still might get this covered if you are lucky.

After running into my first "Voltec Warranty" repair I'm 99.99% sure that every Voltec system repair will be automatically declined as a warranty issue and we will have to fight with GM to get reimbursed for the repair. The answer I was given when they had to do a "reprogram" of a module was "It's a repair and not a replacement so it's not covered by warranty." Needless to say, two weeks and several calls later with the GM support line and I at least have my money back for the repair. I STILL do not have an answer as to who from GM told the dealer that it's not a warranty issue, but I'm again 99.99% sure that they will not be forthcoming on that information despite my several requests to detail it out for me.

Long story short, it seems that unless you happen to be in California and happen to have a dealer that works with Volts all the time, you are going to be fighting every time with GM for them to honor this "Voltec Warranty"

That's your out, tell them you never authorized a non-warranty repair, either get it covered under warranty or undo the unauthorized repair...

This is one reason to get the GM Guard insurance. Overpriced, but being covered for everything mechanical eliminates these hassles. My 2012 is covered for 7 years 111,000 miles.

I think this is an area which GM needs to clean up. One big problem is the dealer specifies the repair but never specifies what exactly the problem was. Since the warranty depends on the cause and not the repair, everyone is simply guessing as to whether this should be a warranty issue or not.

The whole issue of whether the Volt is a "hybrid" model likely results from having different warranties in different states. "Hybrid" may simply be GM's internal designation for a CA CARB state warranty. Hard to know, but I wouldn't get too fussed up or too focused on that aspect of the problem.

Seems to me the rule should be this: If GM can't connect a problem with the Voltec drive train to a cause which is not covered by the warranty, then the repair or replacement should be covered by the warranty. To apply this rule you need to know the cause. If your dealer can't tell you the cause, that's fine. You just need to know that.

This is likely not an issue which a front line service rep will be able to handle. You'll probably have to go up the chain.

Agree that you are off the hook for the cost of the repair because the dealer didn't get your authorization. My guess is the tech assumed the work was covered under warranty.

I don't believe that covers the drive train. I have the same plan. Haven't looked at it but this is my recollection from reading it when I first got it. You may want to check.

Hasn't been my experience at all. I've even had "bubbles in the cooling system" fixed under the Voltec. Braeger on S 27th just north of 894 has been absolutely painless to deal with.

Our upside-down world.

"If your volt is a Hybrid it would be on the left side of the car right under the VOLT Emblem"

Anyone else run into these issues with Chevy?
I had the same Service High Voltage Charging System issue earlier this month and took my precious to the local dealership. They fixed it under warranty the same way they fixed yours (without any mention of a battery drain). I just double checked and the word Hybrid is not anywhere on my vehicle.

So you have unauthorized repairs on the vehicle and a spurious claim. We could assume someone was just unfamiliar with your car--someone that should be familiar, but adding the unauthorized repair to this raises the specter of a scam. Perhaps a saving grace is how GM called the car an "extended-range electric" and many folks considered that term exclusive of hybrids.

This sounds like volt advisor bait.

GMPP usually offers a variety of plans/coverage's (I say usually because I had an array offered for my MY17 Equinox, never specifically got the pitch for my Volt), some with deductible and one without...They can be purchase after the sale at a deeper discount, I believe both forum sponsors claim to offer a discount on them...But the overall fear is, if the dealer is messing up the regular warranty, will this be different? Will they claim that a "software update" isn't specially mentioned in the GMPP so it's denied too?

It unfortunately sounds like this is dealer by dealer basis...Sounds like if you pay the dealer they get their money and then if you call GM corporate they'll just send you a check to shut you up vs going having the dealership correctly code the work as warranty...

While I don't know this, it wouldn't surprise me if dealers get paid a lower hourly rate for warranty work, so they are effectively incentivized to deny warranty claims and make more money (though I'm sure GM does not want this to occur).

That is true and is standard practice across most automakers...However, for service to know something is warranty work but intentionally deny it for some BS reason is usually at the dealership's leadership level...While plenty of this exists, its usually more rampant with anything modified...Countless stories of people showing up with larger rims/tires, claiming an issue that would have nothing to do with the drivetrain yet service denies the warranty claim because the rims were somehow caused the problem...

Unfortunately this was coming from a supervisor. I seriously didn't know what to say to the guy, other then ask for clarification, to which he pretty much repeated the same thing. Of course they also stated the HPCM2 was only for emissions and had nothing to do with the voltec system..... They had several days and this is the best story the can come up with?!?!?!
