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.
An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.
Canada runs its own recall programme, and its campaigns do not always mirror the American ones.
Fuel System
ON VEHICLES WITH EFI OR CFI, THE SPRING-LOCK FUEL LINE COUPLING USED TO CONNECT THE FUEL SUPPLY AND RETURN LINES TO THE EFI FUEL RAILS OR TO THE CFI THROTTLE BODIES AS WELL AS OTHER FUEL LINE CONNECTIONS NEAR THE DASH PANELS ON SOME VEHICLES, COULD DISENGAGE DURING VEHICLE USE. SHOULD THIS OCCUR, LOSS OF FUEL WILL RESULT, PROVIDING THE POTENTIAL FOR A VEHICLE FIRE. CORRECTION: COUPLING RETAINER CLIPS WILL BE INSTALLED ON AFFECTED VEHICLES. NOTE: ESCORT VEHICLES ARE EQUIPPED WITH EFI AND CFI. LYNX VEHICLES ARE EQUIPPED WITH CFI ONLY. EFI - ELECTRONIC FUEL INJECTION CFI - CENTRAL FUEL INJECTION
Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.
