Vehicles these days are computers with wheels, so much electronics to potentially go bad....

 

So if they're set to extended mode, how is the passenger side cured? Did you set it back to automatic?

 

Both sides are extended and when they open they just drop a little lower automatically. it's not a one time thing.

In any event that appears to have done the trick. But I am continuing to observe the operation and so far so good.

 

Sorry, still not understanding what you did. If you've set it for extended, they are going to be out all the time. They won't go back in even when you close the door. And when you open the door, they shouldn't move, right?

 

No extended means that they are lower than normal whenever the door is opened. Did you see the pics I posted?

 

OK, rather than trust Chevy's menu english, and yours, I went and tried it myself. The 3 settings do this: Auto off=stowed all the time. Auto on=deployed when a door is opened, stowed when door is closed. Extended=always deployed. There are NOT two versions of deployed (extended). So back to my original point, your running boards could not be cured and working normally with "extended" chosen. They would be always down, deployed, extended. All the same thing.

 

So I went back and tried it myself. You are correct. Extended does mean always deployed. Mine are not always deployed. They are on auto. I'm not sure why that after setting it to extend initially and then back to auto my running boards have been working. I sincerely thought that the extended setting lowered them more than normal and that was causing the passenger side to work. Apologies for the bad advice.

Since the dealer likely won't do anything about running boards that work I'll have to wait until they malfunction again before taking them to the dealer.

 

OK, thanks for the update and correction. After our running boards on a 2020 Suburban were sticking all last Spring, we took it to the dealer and like almost everyone, there is a magic force field that makes running boards work there. Anyway, they lubricated them. You could see the spray everywhere. As soon as we left, they began sticking again. But gradually, they improved. Most of the Summer and Fall they still worked. Winter will be the big test. It seems as though the lube takes time to migrate into the joints. I like to think I can improve on things, and I do a lot of life hacks. To that end, if they misbehave again, I plan to see if I can install a helper spring to get them started down. When they stick, you can see them try to move, then stop. It's as though the lever geometry is not quite right at the closed end of the stroke and maybe a little help might be all they need. We'll see. Maybe you can try that too. Lube, by the way, is it's own enemy as it attracts and retains more dirt. So I don't view it as being a permanent solution. This should have been a design whose flaws should have been apparent to the freshman engineers that designed them. You'd think a more experienced daddy engineer would have intervened and put in sealed ball bearings.

 

Or maybe was designed by someone who wasn't qualified/experienced but was hired due to WOKE ideals ????

I saw this happen where I worked for 40 years.....now I'm retired.....

 

Another week has lapsed and the running boards are working normally.
