Threadlock ALL mounting bolts

Yes I know safety checks are on me. However, this is something that could be easily prevented by just putting on a drop of threadlock at the factory (as well as spec for service technicians)
1) Front ABS sensor mounting bolt vibrated out and the sensor was found dangling by its wire after braking got weird and herky jerky.
2) Front left brake caliper mounting bolt vibrated out and the caliper rotated off the brake disk with the remaining bolt as the axis. Discovered this as I lost front braking doing 80mph on the way to work. Scared the crap out of me. I feel truly alive now.

Then again one reads of horror stories about fasteners that won't come loose. Personally, I don't like thread locker fluids. A nice little washer will work well as will proper tension applied at installation.
Only bolts I've had come loose are the ones I sloppily didn't tighten properly. I gotten get me a better mechanic!

I've never experinced the unmovable bolt scenario but I'm sure I will.

On the other hand, the front fender bolt that goes into the captured nut in the plastic fender should never have been thread locked. That was a mistake.

If you use any thread locker on any screw that goes through plastic, use sparingly and let it dry a few minutes before putting it through the plastic.... threadlocker eats plastic.

Most common thread lockers do not dry- so waiting a few minutes does nothing. They are anaerobic- only cure, rather than dry, in an air free environment.
Most even require metal to be present- IOW threadlocker on a nylon screw threaded into plastic will never cure for most of them.

If threadlocker eats plastic- how does it stay contained in a plastic bottle or tube?

There was a thread here a while back on what kind of plastic some parts were made of. A spec sheet on the plastic indicated some agents that caused it to get brittle and crack and it included thread locker ingredients. There have been a number of threads about cracked plastics caused by thread locker contact. The tube is made of a different type of plastic. I'll second the warning. Keep thread locker off plastic parts. Even a small amount of contact causes deterioration over a wide expanse.

Cyanoacrylate is used to threadlock plastic substrates, such as Loctite 425. You would not want to use an anaerobic type, such as 242, which contains polyglycol dimethacrylate.

You can just use superglue for plastic substrates, but it has a higher strength than Loctite 425 so you have to be careful to just use a tiny dab.

Interesting- I've used a lot of Loctite over the years but have never tried to use it on plastic and apparently never got any on plastic accidently...as I've never observed that.
So some plastics have an aversion to it but some don't.
My favorite is the blue LocTite gel in the push up tube. Much easier to use and never leaks in your toolbox.

I remember back when Timex came out with one of their first digital watches and it was plastic. I had one and I inadvertently splashed some solvent (IIRC acetone) on it and it crumbled into little pieces right before my eyes, didn't melt, crumbled. Weird.

Here is a reference that discusses some bolting strategies. I think there are several more if you go looking.

Bolt Science Web Site

Tests were done (video) that demonstrate you are better off without a lock washer than with one.

There's lots of good info but I recall there was more some years ago.

The conclusion I read previously suggested to do away with lock washers and use either Nyloc nuts or a chemical fastener (Loctite)
