2020 GT issues
Bought a 2020 GT with 65k miles on it a few weeks back. Yep, high mileage with rental use. Purchase included a 4 year 48k mile bumper to bumper warranty.
Today I went to change the plugs. The first three came out and looked ok but the 4th came out wet. The liquid has a definite chemical smell to it. Here are pictures. What does the wet plug mean?
Second issue: shifting from park to drive/reverse there is a weird noise.
. It sounds almost like the the brake pads releasing . I’ve also notice some pretty jerky shifts in lower gears. Is this normal for a cx5?
Third issue: CARFAX showed front rotors were turned and new pads installed. Didn’t see a service record for rear brakes but dealership said they had been replaced as they had 90% left. I always get squeaking in the morning and they feel soft compared to other newer cars I’ve driven. Is this just a Mazda thing or is something wrong?

Wet plug can be any number of issues, none of which are good.
Shifting sounds a bit clunky as well, my 2020 is fairly quiet in that respect.
Mazda brake service tricky and requires specific steps be taken or it can cause issues with the electronic braking system.
Not saying that is what you have going on, but I would get it ALL checked by a qualified Mazda service dealer to verify everything is correct.
And yes, I agree on the brakes, they are the only week spot on this vehicle for me.
They do seem soft to me as well and are not up to the stopping grip I'm accustomed to.
But like I said, that could just be me, and I will be installing performance pads and probably rotors at my 36K service.
And performance calipers down the road as well, if the pads/rotors don't suffice for me.

Changing the filter and fluid in the transmission likely would improve the shifting and noise. An often ignored
maintenance item.
Where was the plug wet at? The external ceramic and hex nut may just be left over from engine bay cleaning.
Wipe out plug hole and clean plug and keep an eye on it.
I defer to Lobstah on the brake issue.

The photos show the fourth plug to be wet on the engine side, so it is not from “engine bay cleaning”. Since the other three look okay, the wet plug may not portend well, although the electrodes and insulator don’t look bad.
