It's been a while, but finally bit the bullet and took my 2020 Hybrid with 25,000 miles in for the trans rattle on cold starts. The software update did help and almost eliminated the noise, but if I shifted into Neutral when cold it still rattled away. The update did not correct that issue. Noise never got any worse during the mileage I had it, just was annoying on cold days. I made a comment to the dealer about what a pain it must be to have to pull the engine/trans out of these vehicles. He said it's not all that bad and they've done more that their fair share, so they're pretty good at it. Thought that was interesting. He also mentioned they're seeing some new Maverick Hybrids with the same issue. It's a shame Ford still hasn't remedied the issue after all this time. Supposedly there is not an updated flywheel damper, still replacing with the same original spec. I'm extremely happy the dealer gave me an Edge loaner that was brand new, although the mpg sure is a lot less! I'm sure the car will be fixed properly, just disappointed in Ford who is apparently willing to make all these repairs rather than correct the source of the problem. Also getting the Deep Sleep mode fixed after two years. Battery always checked out fine, but they have enough history with this issue now that they're just going to replace the battery under warranty. I was told don't expect more than 24 months out of the replacement.
