Once you learn to leave things alone, and not mess with em, they are magically much nicer to always drive.

Granted I did tune my truck but I managed to not fall down rabbit hole.

lmao this is true. but once you get in the habit of modding things it is hard to not touch em

Update, car is back at dealer for the ****ing DEF poor quality countdown to F u mode

Did they replace the sensor last time?

This time they claimed that the downstream nox sensor was acting up, but after resetting the speed limit mode they gave it back.

What year cruise is it? There was a NOX sensor recall for some:

It definitely seems like a crapped out NOX sensor, but it could be the DEF injector or the pump, too.

Failed downstream NOX sensor doesn't cause limp mode, just a CEL and no remote start. Usually you'll just get P11D7.

Did you pull any codes? Wonder if it's DEF tank related .. they are covered until 120k I think. Has yours been replaced?

I thought if the NOX sensor was reading wonky, the PCM would 'assume' that the DEF was 'low quality' and start derating the drivetrain.

I didn't have a chance to pull the code, and remote start was still working.

Dealer claims that the nox was reading weird then normal numbers.

Did you look at the link I posted? There was a recall for NOX sensors in your year Cruze.

Since it's a recall, especially on an emissions device, should be a free fix.

I did the recall (it is free) to replace NOX1, they also run a forced regen and flashed a new tune which now makes my regen cycles at low speeds feel like pretty good cam surge. But I haven't had any CEL and usually regen at highway speeds so I just deal with it.

If you have torque pro, there is a plugin on the app store for the CTD specifically. It allows you to force a service or normal regen and allows you to see other PIDs. I forget what it was called ..

Say it isn't so. I guess I just got lucky in my posts.

Like others have said, if it's the NOX sensor it's covered. I don't have access to the recall/bulletins anymore since I'm out of the dealership world but it should be a straight forward repair(provided that's actually the problem).

Only nox 1 is covered and the one in question is not covered by any warranty.

Apparently it threw p20ee, which I think it has randomly thrown since I got it.

Delete and tune is looking good

To be honest, that's probably not a bad idea. I personally don't know what's involved in that, I'm sure others will chime in but it would definitely get rid of a lot of headaches.

What's sad is that the months when it drives normally, I love the thing. Great mileage and comfy car.

Just annoyed with a three year old car chewing up sensors

My gas one started drinking antifreeze about the same time. Too bad, it was a good car except the crappy shifting trans.

Where's the gm leghumper now? Lol

Was the NOX Sensor recall ever done on you car, though? From a quick google search, there were two different recalls, and in the second one there was an update to the PCM that is supposed to rectify the NOX Sensor 2 issue. Also, have they checked to see if the DEF injector is clogged?

Recall 1

Recall 2, newer and supplants Recall 1

my GM leghumping was satisfied when my wife's 13 focus kept eating DCT clutches every 10k miles :nick::nick::nick:

how is the car besides this DEF BS?

My 04 Cavalier just passed inspection and is about to turn 200k miles. I'll hump GMs leg any time.
