Here's the exact quote from the Title of the TSB:My best guess (MBG) is that VBM may be 'Vehicle [or Video] Backup Module'.
Maybe it's time for GM to provide an acronym decoding ring (with an embedded RKE module) to new owners, or at least a glossary in the back of the owner's manual.
Yes, I still have the problem. I have had the car for 11 months now and am getting really fed up with GM not doing anything about the problem. Just promising us a fix that never shows up.Anyone still having this problem? Still no fix from GM according to the dealer.

I'm not sure I have the same problem. I can drive for a while and the lines are still intermittent. If I put it in neutral the lines come back. Put it back in reverse and they disappear.I don't think there ever will be a fix. There is just no computer that can load everything that quickly.
If I take my time and let the car fully boot up before touching anything besides the engine start/stop button everything works fine.
If I rush it, then the computer at least gives a camera, albeit without grids, and apparently sometimes upside down!
Yes, the frame rate increases a lot when the lines are off. Probably a software issue as I don't think the hardware can't handle the lines too.I've noticed lately that the lines also appear related to the choppy movement and poor image quality of the backup camera. When my lines disappear, the image is much crisper and moves smoothly as I back up. It seems GM has just not specced good enough hardware, or the programming is subpar as there are plenty of other systems out there that don't exhibit this behavior.
I am noting this as well, that the lines disappear sometimes even if the vehicle has been driving for a while. I'm just glad we don't have to wait for the system to boot to get a video stream, lines or not. I do agree the lines are helpful but I assume we can put this on the list of bugs GM will never address. The lack of lines during booting I assume is simply a limitation of the fact that the software to draw the lines isn't ready yet.I'm not sure I have the same problem.

Yes, this has been an annoyance for quite some time now.My 2019 Buick Regal continues to experiences randomly disappearing back-up camera guide-lines. When shifting into reverse, the lines are there for 3-5 seconds and randomly disappear just when I need the lines the most. It is as if the guide lines time out or the virtual button in the lower left was pushed. The icon to turn the lines on also disappears and I must shift to neutral and then back to reverse to get the lines to return. This generally occurs on the first start up when I’m leaving our parking garage and randomly other times later. It is really annoying and actually presents a significant safety issue.
It is the Avenair model which is overall a nice car but after having used a back-up camera with guide lines for a number of years on my previous cars, I rely on the guide lines.
Dealer say need to wait for fix from Buick. I've been waiting too long!
