General Motors has released a fix to address an issue related to the turn signal indicators on certain examples of the 2022 model year Chevy Silverado HD and GMC Sierra HD.
The problem: affected Chevy Silverado HD and GMC Sierra HD trucks may have a condition in which if the driver enables the passive door lock feature and a passive door locking event occurs after occupants exit the vehicle with the key fob, the rear or front and rear turn signals may turn on and remain lit. Both turn signal/hazard indicators on the instrument cluster may also turn on and temporarily remain lit. The resulting battery drain may cause a discharged or dead battery.
The hazards: a drained battery does not pose a direct safety hazard to the driver or vehicle occupants, however this problem could leave the user stranded without a mode of transportation and should therefore be addressed as soon as possible.
The fix: GM dealers are being instructed to reprogram the body control module. This should prevent the turn signals from remaining lit in the above-described scenario.
Affected components: body control module.
Affected vehicles:
- 2022 Chevy Silverado 2500HD
- 2022 Chevy Silverado 3500HD
- 2022 GMC Sierra 2500HD
- 2022 GMC Sierra 3500HD
Number of affected vehicles: it’s currently not clear how many 2022 model year Chevy Silverado HD and GMC Sierra HD trucks are affected by this problem.

How about a fix for the infotainment system going black screen intermittently.
I had a 14 and have an 18 and have had no issues.
I put a carplay/AA head unit in my 04 and everything else that takes a double din.
Just reinforces my opinion about these newer trucks being 4 wheel computers. Technology is great but to much technology can be detrimental. I think a lot of this technology is to ensure you have to return to a dealer for any repairs as small independent shops are not going to have the necessary computers to work on these vehicles. Back in the 90s they started going to specifically designed computers that each corporation used just for that purpose, only GM vehicles could use their computers to diagnose problems, and Ford and Chrysler did the same. It’s all part of the process to keep dealerships in business for repairs. Years ago as soon as the warranty expired I never returned to the dealer for anything, if I couldn’t fix it I took it to an independent shop as their labor rates were less, not anymore. Now you need a computer program to tell you your gas cap isn’t tight enough. Lol
“I think a lot of this technology is to ensure you have to return to a dealer for any repairs as small independent shops are not going to have the necessary computers to work on these vehicles.”
The US Government ended that in 1996 by forcing all cars to use the OBDII standards for diagnosis. When software reflashing became important, SAE J2534 became mandatory.
The problem generally lies with mechanics. Dealers hire young guys and put them through a training program that emphasizes reading the service manual and bulletins and following established diagnosis procedures. When a new platform comes in, there’s requirements for techs to be updated via online learning.
The problem is the boomer mechanics who think that competency is gained only by experience and not by reading and learning. If you look at specialty performance and off-road garages, who are run by younger guys, they have no problems diagnosing and working on newer vehicles.
