2003 VOLVO S40 Electrical System Problems

PRIOR TO LATEST INCIDENT, THE CAR HAD OCCASIONALLY GONE INTO "LIMP" MODE, STICKING IN 3RD GEAR BUT DRIVABLE. THAT PROBLEM WOULD GO AWAY AFTER A DAY OR SO.

FURTHER, THE PARTS ARE BACK ORDERED AT THE DEALER, BACK ORDERED AT VOLVO NORTH AMERICA, BACK ORDERED AT VOLVO IN SWEDEN, AND THEY CANNOT EVEN GET ME A DATE WHEN THE PART MIGHT BE AVAILABLE.
