TSB Issued Over Distorted Backup Camera In 2020 Chevy Silverado HD, GMC Sierra HD

General Motors has issued a technical service bulletin (TSB) to address an issue with the trailer backup camera in the 2020 Chevy Silverado HD and 2020 GMC Sierra HD pickup trucks.

According to the TSB, some owners of affected trucks “may comment on narrow guidelines and a zoomed out/fisheye appearance from the rearview camera.” The cause of this problem “may be an issue with the Video Processing Control Module (VPCM) calibration distorting the view from the rearview camera and decreasing the width of the guidelines,” the TSB also says.

To correct this problem, GM instructs dealers to reprogram the VPCM with a more up-to-date software version. Only trucks equipped with the Surround Vision – Trailer Vision camera system (RPO UVI) will be affected by this problem, as the software issue is for the optional trailer camera and not the regular backup camera in the truck. This problem can also extend to 2020 Chevy Silverado HD and GMC Sierra HD trucks sold in any market including the United States, Canada, Mexico, Israel and Thailand (ASEAN).

This TSB was initially released on August 24th, 2020, but GM later released an updated version on October 29th, 2020 providing dealerships with part numbers for repairs and other parts-related information. Owners of GM full-size heavy-duty pickup trucks who may be affected by this problem can speak to their dealership to have the problem addressed. The TSB did not indicate how long these repairs may take.

Certain light-duty Chevy Silverado 1500 and GMC Sierra 1500 trucks were recalled earlier this week due to a problem with the driveshaft welds. Only a small number of trucks were affected by that recall, although it included vehicles from both the 2019 and 2020 model year.

  1. It’s time they fixed previous years garbage too! Have a 2018 Sierra and I’m on my second camera, and needs to be replaced again. Distorted and blurry!

    1. Tell the dealer to test the coax wire from the center console to the camera.
      Probably damaged and not sending a good signal

  3. Rear camera works when it wants too. Started soon after I bought it. Dealer said could not find anything too causing problem.

  4. This is what happens when manufactures are pressed with customer demands and they go to a third party to get it to market faster. Sounds like Ram and GM uses the same source.

  7. Mine is a blue screen. I see recalls on years around the same time but guess mine isn’t part of that recall. Makes no sense to me. From what I’ve read regarding those recalls is that it is a software update. I am not paying for them to assess if it is a software update nor am I paying for a software update. That is not my fault so we just deal with it I guess. It is not helping us liking Chevy that’s for sure.
