General Motors has issued a service update for certain units of the refreshed Chevy Silverado 1500 pickup equipped with the 3.0L I6 LZ0 turbodiesel Duramax engine and non-ETRS transmission due to a problem related to a faulty engine control module (ECM).
Affected Silverado examples may have a condition where the ECM doesn’t properly respond to certain service tool requests for the datafile CALID (part number) or CVN (checksum).
If the ECM were to fail to respond to service tools, then affected Silverado 1500 units have the potential to fail an emissions inspection/maintenance test. Certified GM technicians will be instructed to inspect the ECM and replace as necessary, free of charge. Notably, it should take techs roughly 30 min to perform the fix.
General Motors did not specify exactly how many units of the 2022 Silverado 1500 this service update covers. The service bulletin covers 2022 GMC Sierra 1500 units as well.
GM will notify owners of affected vehicles and instruct them to make an appointment with their dealer. Any owners that are unsure whether or not their vehicle is affected by this recall can visit my.gm.com/recalls and type in their VIN to see any open recalls or other actions that may be active on it. Owners can also reach out to Chevy or the National Highway Traffic Safety Administration (NHTSA) directly with any questions or concerns they may have using the recall number and contact information included below.

Why is the Max Tow Package no longer available with the 3.0 Duramax?
The LZ0 only comes in the 2023 1500s, so it wouldn’t be the 2022s getting the software update.
I previously had an EcoDiesel. These small diesels produce a lot of TSBs and recalls. One time went in for annual oil change and 18 outstanding. Never had a issue but diesels have a blue million sensors these days to run optimally avd safeguard the engine; so lots of software reflashes for updated code to analyze all that sensor data.
The Ecodiesel was junk from day one, including the 3rd gen, hence why it’s no longer around.
GM introduced new technology in their vehicles especially SUV then spend 10 yrs to make corrections on their faulty stuff. After 10 yrs they then introduce a new technology 😂. Please GM we don’t want new technology just stay with the technology u spent 10 to make it working.
