What kind of ChinEglish is that? Very uninspiring...
If you have a Mav Hybrid and a coolant leak or smell of burning coolant, the very first place you should check is the heat exchanger. It is hard to believe these dealer techs do not have access to (or do not bother to check) a factory knowledge base.
If you're asking me how the #1 most American Made, American content, American Engineered truck is holding up compared to the most Mexican-made truck - well let's just say the doors aren't falling off 🤡...
How many miles on the truck?
I'd say everyone with a Maverick should take a look at their hinges asap, and keep an ongoing eye out for anything unusual. Better to catch it while you still have a warranty!

normal exhaust condensate doesn't leave a puddle. A few drops, yes. A puddle - no.

I am surprised the boot is serviceable, usually a bad boot requires replacement of the whole shaft assembly unless you use a janky aftermarket split boot.
If it were me I'd start asking questions.
You are. Most reports on this forum are stock trucks, and there are a lot of them. Threads and posts abound on this subject...
If it was just one report, I would link you to it to save (my own) face. But there are so many, I'm not going to link to them, to save you the embarrassment.
There are many reports of Mav Hybrids with CV Axle problems, and as noted the problem is exacerbated by a lift. But it happens to plenty of stock trucks too.
Most of the people who experience this issue are driving bone stock trucks. It is a legit issue, some sort of defect in the shafts (either material, design, or manufacturing).
I hate to say it because it should not be this way, but nothing productive usually comes from letting the service dept know about problems you read about online. And it is usually not a good idea to project the root cause. Just take it in, tell them the symptoms (shakes when accelerating) and...
