Rhythmic clunking when moving forwards

[TBondu]

Just got back from a weekend camping trip. Everything went great (truck pulled three camper very nicely, the onboard power was a lifesaver when temps were near 100 to run the camper AC). However, when leaving the campground I noticed a new drivetrain noise. There's a rhythmic clunking (imagine something on the driveshaft that continually hits the underside of the truck as it rotates). Only does it in drive and will do it in all electric mode as well as hybrid. My hunch is it's something with the electric motor but thought I'd check here to see if anyone else has had the issue. I made it the 160 miles home just fine. No vibrations or warnings going 65 on the highway.

Welp, I think I found the issue. This heat shield (circled in red) has come unstuck from the body and was rubbing on the driveshaft. Any recommendations for an adhesive tape to apply until I can get it back to the dealer?

Someone else on here has pix of the same issues. Must be a batch of bad glues

I just had the noise problem but mostly when driving in reverse. The dealer fixed it today.

I would try some of the silver thin metal tape they use for house duct work. 3m double sided automotive tape should work very well also.

I had the extract same thing happen this week. Came off right above the drive shaft, by the U joint.

7 hr job at the dealership to remove the shaft and epoxy it, which wasn't done at the factory like it was supposed to have been.

Same issue - picked up my power boost yesterday and a heat shield is not properly attached so that it rubs against the universal joint of the drive shaft.

Power to the forum!
This is the kind of thing that makes modern vehicle ownership so different than when I was a young fella.

Dealer told me they could order replacement panels, but the glue line on the edges would be just as narrow, and probably not hold any better than the factory installation. So they used some kind of epoxy to glue them back in place. (Mine were not damaged, just loose.)
