My thoughts on this, not knowing details of the pack?
LFP is a safe chemistry, but with the Californian summer coming, the 2.75 mOhm is too high for reliable operation.
Replace it with a cell that has a low impedance, but there's no hurry.
If it had been any other, dangerous chemistry, f.i. LMO, NCA, NMC: DON'T DRIVE OR CHARGE, GET THAT CELL OUT NOW!!!
