Car Issues Getting Me Depressed...

I seem to be having a run of bad luck...

First I burst a tire and bent the wheel ($950).

Then my wife's Jag has a check engine light come on and during the repair they also found oil in the break fluid reservoir ($1100).

Next, the interior of the c-pillar cover starts to rattle due to a broken plastic tab--it's been 3 weeks with no sign of the part showing up any time soon. At the same time, had the fuel filler neck replaced (under warranty) due to that little green flap sticking open.

Yesterday, I drove very slowly over a speed bump only to get hung up on it once the front wheels had cleared. I looked this evening to find that the cage covering the underside of the engine bay had come loose at the front--the mesh was torn away at the bolts. I can't see any other damage, but who knows. (Can this be repaired, or must it be replaced?)

Finally, and worst of all, I discovered a new noise this evening coming from the rear passenger side that sounds like a rattling or grinding noise. My wife describes it as a "grumbling rattle," as if something is vibrating or there are rocks rattling around in there. We first noticed it when making a left turn from a dead stop when at low revs building up speed in 1st gear. I drove around a bit more, trying different scenarios--left turns, right turns, MPS on/off. The noise comes and goes in intensity and seems more subdued if the MPS is switched off, but there are too many variables to be sure. At one point I accelerated pretty hard and the noise continued each time I'd step on the accelerator. Any ideas? I suppose that something associated with that fuel filler neck could have worked loose. All sorts of terrible and expensive possibilities are running through my mind. One further note is that the car drives fine, and handling, etc. does not seems to be affected.

I really am depressed...
