Rotating mass maybe?

That and usually they have to torque limit the motors on autos to protect the gears, which may affect mileage.

Speaking of, first official fill up after filling it when I took it home... 435.3 miles with 11 gallons of diesel. Savings of over 50% compared to lugging truck around.

That's just fuel savings, never mind 3/4 ton maintenance etc 8-)

True. Always forget damn slushboxes lol.

Since I got my morning shift back, maybe ill stick with a manual then lol. Nice 40mpg. whats your driving like? lots of city or highway

80% highway 20% city

Well Frosty, you were right.:|

So far, have had three codes thrown and is currently in countdown to death due to poor DEF quality.

Awaiting what the local Chevy dealer says after their "diagnosis" and then I evaluate.

wow.

Seriously? Sorry man :(

What codes did it throw?

P20EE, twice, first time I cleared it
P20E4, once

And the more fun one, the dumbass GM countdown to death on DEF quality.

Sorry to hear about that. If they say its due to bad DEF tell them to test it and let you know the results. I believe a Refractometer is what they use?

The DEF was flushed and refilled with new fluid when I took the car back to where I got it last time for this countdown BS. If we assume they are not frauds, its got good DEF. More than likely a sensor issue.

What is this countdown to death you mentioned? Like a time limit when it will just shut off the engine?

Interesting. Did you ever remove the existing DEF fluid and replace with new since it does break down? P20EE is poor SCR efficiency, hence poor quality light.

The countdown isn't GM, that's your friends at the EPA ! Low DEF will also trigger a countdown. A clogged DPF can cause a countdown to shut off. All to prevent you from driving a dirty diesel :|

Sidenote, what's the NJ inspection procedure for diesel cars?

Yup, mid travel to Philly yesterday I ran out of time. Could not go past 65mph coming home and in like forty miles I will be limited to 55mph :-x

Again, the dealer I got it from claimed to have flushed and then refilled the DEF tank when this countdown and code came on earlier. Obviously they did not fix whatever issue it was so I sent nasty email and took it to a third party Chevy dealer.

Still waiting for diagnosis from Chevy dealer. Are NOX sensors covered under 80k emissions warranty?

Could the DEF line be clogged?

Or the injector itself.

Was hoping to avoid working on the car myself since it came with warranty

Can't blame you for that. My wife's car is the only car I've been around with a warranty and it didn't do us any good. Hopefully it works out better in your case

Any update?

Initial issue was low DEF (there is a backstory) and then the dealer could not get the car out of the speed limit mode. Dealer called TAC and somehow they managed to reset the car which fixed it. They managed to run through all the diagnostics and every sensor checks out good. So I am happy with that, only charged me $140 for materials and diagnosis which is not terrible IMO considering they were perplexed for a couple days with it. [This is all at a third party Chevy dealer]

The back story, about a week or so ago prior to this incident, the same symptoms showed up. Angrily called dealer I bought it from they told me to bring it in. Was then told their tech flushed and refilled the DEF, fine, all the codes were gone I was happy. I wrongly assumed that they actually did the ****ing work they claimed, but, lesson learned.

And yes, super embarrassing to have the tech explaining how I need to fill the DEF every oil change :|

There is a level sensor with a display on the DIC, not sure if you saw it. It will say "DEF Fluid Level OK" until 33%, then it will decrease and show a percentage. I usually grab a peak bottle from walmart and I'm good for another 10k miles

So how are you liking it? Any words of wisdom for someone shopping? Is there a preference on year etc?

Um, for its intended purpose of getting better mileage than my truck. Its been great. Averaging around 45mpg every week and the ability to go ~600mile on a tank is really awesome. Leather seats are decently comfy and other than the adjustment from a open bench seat roominess to the small front chairs, its been nice.

So far no issues with gas stations trying to fill it regular, but BJ's has a diesel only stand so its fairly safe from idiots. I do find it amusing when people ask if its peppy, pretty sure my truck is quicker. :lol:

Currently driving with a SES cause I need to replace a EGT sensor, believe #2 but not caring until next paycheck cause it doesn't seem to effect any of the MPG numbers. Other than that, no complaints, come spring it will need new tires and brakes but it does drive nicely.

tune it for moar boooooooost for peppy!!!

glad you're liking it. 45mpg isnt too shabby
