I had the same thing happen to my 05 x5 4.4 I replaced the battery but I was in the process of getting an alternator due to a high pitch whinning noise which I suspect the bearings in the alternator. Anyway both were replaced no issues until the next day. I had a trans failsafe program error. Reset that fault and out of the blue I am getting ABS /BREAKS 4×4 TRACTION Control lights coming on the dash. Can't figure this out yet. This is driving me crazy. The car can sit over night and when it starts no warning lights and boom about 30 minutes later warning lights pop back on. Any suggestions?
