Noisy rear suspension

A squeaky sound coming from underneath your 2015 Nissan Versa Note, even with low mileage, can be worrisome. While it's difficult to pinpoint the exact problem without a physical inspection, I can suggest some potential causes based on your description and the symptoms:
Possible reasons:
Worn suspension bushings: These rubber parts connect various suspension components and can dry out or develop cracks over time, resulting in squeaking when they move.
Loose sway bar links: These control bars aid in stabilizing your car during turns and can become loose, leading to clunking or squeaking noises.
Loose or worn-out serpentine belt: This belt drives various accessories such as the alternator and power steering pump. When it's worn or loose, it can produce a squealing sound, particularly when starting or accelerating.
Dry or worn CV axle boots: These rubber boots protect the CV joints that transfer power to the wheels. If they are dry or torn, they can cause squeaking, especially during turns.

Additional information for diagnosis:
Does the squeaking occur consistently or intermittently?
Does the sound change in pitch or intensity when turning or braking?
Is there any noticeable vibration or pulling to one side while driving?
Have you observed any other changes in the car's handling or performance?
Recommendations:
Schedule a service appointment with a qualified mechanic: They can examine the suspension, brakes, and other potential sources of the noise and provide an accurate diagnosis.
Do not disregard the noise: Ignoring it could lead to more serious issues and costly repairs later on.
Gather any additional information you can: If the noise seems to occur under specific conditions, make a note of them to assist the mechanic in their diagnosis.
While your low mileage may suggest that the issue isn't significant, it's always best to have it checked by a professional. Early detection and repair can save you time, money, and potential safety risks in the future.

water may be in spark plug cavity.

They are a bit noisy sometimes, hopefully it's nothing serious, good solid bikes those so you should be good.
Check you have the correct oil in there, if your running a thin oil, it may increase the noise and wearing.
Try this, when its parked up and idling cold (when you start it up in the morning) get a screwdriver or somthing similar place the metal part of the screwdriver on the engine where you think the noise is coming from, then put your ear on the handle, doing this you will be able to pin point exactly where the noise is coming from buy moving the screwdriver around the casting also you can really hear her tick.
do it again when she's hot noting the difference of any. If it continues to get noisier, strip her down and have a look in there, could be just the tensioner/guides.
good luck

The problem you describe is coming from your suspension .if your having fuel problems and your car is puttering or surging this will cause bad suspension to sound very noisy and make a lot of different shake and rattles

Sounds like the water got in somewhere crucial and is preventing the components from telling the coil to spark.

Don't laugh now, but try hitting any suspect areas with WD-40. I recently learned the WD stands for water displacing. It was initially invented as something that could remove water. But it is flammable so exercise caution.

This is surely frustrating and thankfully it doesn't happen often to Harleys. I sure hope you find the source and get it sealed.

I rode with a group of 15 bikes from south WI to the eagle rehab place up in Minnesota. It rained on us for almost 90 minutes but not one bike quit running. So, when things are sealed as they should be, Harleys can run in the rain.

Hope you get this solved and get back on the road.

MOST LIKELY THE FRONT AND REAR SWAY BAR RUBBER BUSHINGS ARE THE SOURCE OF THE PROBLEM, ALSO THE FRONT LOWER STRUTS CAN BE NOISY AS WELL.

Your wheels are probably rubbing against your brake caliper, or the dust shield.

if it just clicks, firstly hook up jumper cables to battery, if it still just clicks, it will need starter motor brushes.
