That was my first thought. Battery probably has a defective cell.

Don't normally drive our XC70 2003 vintage but in the last fee days noticed it was looking odd. Lopsided. Low. On the drivers side. Pull out the jack lift up the body and spot the lowest portion of the spring had completely broken off. Have never had this happen on any other car in thirty five years...

Since I need to replace a 2003 grille, subscribed. It would be fun to update with a later grille.

Any idea how to deprogram the seat positions?

Swapping cars is almost sounding like the best solution.

Have your battery and alternator checked. Weak units will cause electrical chaos on most cars these days.

Clunky could be sway bar bushings. 100k on 03xc70 still with original shocks. But time to do links.
I don't drive it often (it's wife's car) but can tell they're needed.

Same thing happened to wife when in middle of nowhere she got some no name coolant.., it was at minimum so barely needed to add anything.
I would just go to parts store buy something "ok for Volvo" name brand type.

How's the oil and coolant level? If ok and no codes, can't say there is anything to worry about.

And you had no problems before the fuel pump was replaced?
Hmmm suspicious say I.

Btw where is the fuel filter on these cars?
