A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

THEREFORE DEALERSHIP IS NOT GOING TO REPAIR THE DEFECT. I RECEIVED NO SUCH NOTICE. WHEN I CONTENDED THAT THIS IS A SAFETY ISSUE AND SHOULD IMMEDIATELY BE HANDLED AND MY CAR HAS 80,000 MILES ON IT AND IT HAS NOT EVEN BEEN 10 YEARS THEY REFUSED.

THE HYBRID SYSTEM ON THE INVOLVED VEHICLES CONTAIN AN ELECTRIC VEHICLE (EV) FUSE WHICH MAY MALFUNCTION IF THE VEHICLE IS REPEATEDLY OPERATED IN EV MODE UNDER HIGH-LOAD DRIVING CONDITIONS, SUCH AS DURING A LONG HILL CLIMB. IF THE FUSE MALFUNCTIONS, WARNING LIGHTS AND WARNING MESSAGES WILL ILLUMINATE. IN SOME CASES, THE VEHICLE CAN BE DRIVEN, BUT WITH REDUCED POWER. N OTHER CASES, THE HYBRID SYSTEM COULD SHUT DOWN RESULTING IN THE LOSS OF MOTIVE POWER. POWER STEERING AND BRAKING WILL NOT BE AFFECTED. LOSS OF MOTIVE POWER WHILE DRIVING AT HIGHER SPEEDS CAN INCREASE THE RISK OF A CRASH.
