hello everyone - I hope you can provide some insight or assistance. For the past week or so, I have been hearing a sloshing sound near the passenger rear door - my gas tank is on this side. I hear it when I brake and then proceed to accelerate - i hear liquid sloshing around.
Any thoughts?
thank you

Well, your fuel filler neck is on your passenger side but the gas tank is under your entire rear seat. Think of it as a kidney or a bean allowing the driveshaft to go under its middle. All this to say, if the tank was sloshing you should hear it on both right and left sides.

Have you had a lot of rain in your area during this period?

Can you pinpoint whereabouts the sloshing is coming from? (You might need to sit in the back while someone else drives).
If it's overhead, then it might be some water in the sunroof assembly, although if it is enough volume to slosh around, it should also get your headliner and/or C-Pillar trim wet. Feel around for dampness.

If it's coming from a little lower, then I'd check these:
  1. Your passenger doors. If the drains are clogged and the weatherstripping fails, the door might hold water.
    Just open and shut each door to see.
  2. The rear quarter panel. This has to be accessed from the trunk and you remove some trunk liner clips to see if water is accumulated there.
    So those area you're looking at is directly behind the rear wheel, above the bumper cover.
  3. While in the trunk area, you might as well check the spare wheel compartment.
    This is easy and more likely than #1 or 2 above.

Thank you @EdBwoy I appreciate all of your suggestions.
Yes, it has been raining quite a bit here (Maryland) for the past 3 weeks off and on. I've had someone sit in back seat while I drive and it is not heard on both sides. It is consistently heard on the rear passenger side. I will try going in the trunk and removing the liners to feel for wetness. thanks again - i will let you know how i make out shortly.
