Received a recall in the mail today, N192273630. The engine control module in these vehicles may not adequately diagnose or illuminate the CEL when frequent regeneration of the diesel particulate filter occurs
GM is currently working on a software repair... :mad1
Dealer called me today to schedule replacing my block heater and install the emissions software update at the same time. They confirmed the software update is already available.
The recall is in Onstar on mine but its for a 2019......but it was sent to my 2018....ok, I'll see if dealer has heater cord and knock it all out at once.
I got the same thing. I am just afraid if I bring it in and get them to reprogram the ECM then later I may have to face some other issues that they mess with it. It has been trouble free for 19k already. Knock on the wood.
Considering the mileage sucks anyway and I'm on the edge of the emission warranty the only thing the CEL is going to tell me is to hit the bank for a loan to fix it . ( and get out the scanner I now carry on board )
We will continue to pray for hail in the mean time.
Had my truck in yesterday for the DEF regen frequency recall. Can't tell any difference in anything yet. Before, my truck would regen anytime it read over 63% on the insite monitor. Right now I'm setting on 44%, interested if the soot accumulation goes higher before regen now.
I just had the recall done and now my cts2 shows 0 for DREG (distance since regeneration). I'm going to call Edge Products in the AM to see if they've heard of this.
Had the 4500 done a few months ago and didn't notice any difference but then I never noticed or could tell when it did its regens. Mileage stays pretty consistent ( like I care about mileage) but no change in drivability
So if this gets updated, it could possibly put the truck into limp mode if it senses incorrect regen intervals? Anyone put much mileage on since getting this recall done?
Fyi all of y'all are welcome 2 months my truck sat down because of this and another tsb on the secondary fuel rail. Made gm pay for it all and give me two months down time pay. Terrible experience love my truck but GM sucks. Took me threatening to a lead manager that I was going to haul the truck to Detroit and drop it off at their office with fuck gm written in spray paint all over the truck.
My Duramax is a 2018. I do not know what other years may be impacted.
