Beware- GM 'may' start this on our gas engines - someday??

[Retired Bob]

2016-2017 Colorado and Canyon models and 2017 Express and Savana models are available with the Duramax 2.8L turbocharged diesel engine (RPO LWN). (Fig. 9) Various performance conditions, such as poor drivability, increased emissions, knocking noises, engine damage and black exhaust smoke, may be caused by an aftermarket power-up kit or other aftermarket hardware.

 

Any time an internal engine hard part failure is found, it’s recommended to check for the presence of non-GM (aftermarket) calibrations. The use of parts, control module calibrations, software modifications, or other alterations not issued through GM will void the warranty coverage for those components damaged by the installation of the non-GM calibration or alteration.

 

If a non-GM calibration is found, a GDS 2 screen shot is required by the Calibration Group. To take the appropriate screen shot, navigate to Module Diagnostics > Engine Control Module > Identification Information > Calibration History.

 

Depending on the computer screen configuration and the Number of Calibration History Events Stored, it may be necessary to take two screen shots in order to retrieve, save and view all of the needed information. The report should include the VIN, Calibration History, Calibration Verification Number History and other associated parameters. The VIN must appear on the same screen as the calibration numbers.

 

Create a report by selecting the Create Report button. (Fig. 10) Email the report to the GM Calibration Group.

Old news. This applies to all engines with severe warranty issues.

Aftermarket stuff might void the warranty?! Stop the press!

[JRL1164]

Yeah this is already being done across the board.

[RyanbabZ71]

They already do this and have been for years

Can I be the 5th guy to say what the guy before me already did..lol.

 

This is already happening but thanks for passing along to those that aren't as tuned in to the industry.

No way! News to me.

 

 

 

 

 

 

I just couldn't say the same as everyone else.

Easy to get past. Hand the tech a bottle of Crown and your warranty claim will go as planned.

Tough crowd today.....

Then you may get a tire rotation instead of an oil change lol

Would have been easier to just post the link

Or just buy an older GM truck and do whatever you want to it without having to worry about it. [emoji1]

This all started around 2008-2010 when "superchips" first got popular and they made national news when trucks started exploding. I remember it being a big deal when Ford discovered they were the cause for the massive amounts of engine failures.

We've always have to do this on engine warranty jobs for years. The one exception I have ran into so far was a Chevrolet Spark where GM told me calibration numbers were not needed for the engine.

 

And No, there is no getting around this by paying off the tech working on the car. GM NEEDS these calibration numbers before they will approve work to your vehicle.
