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.
BRAKE LINE PUNCTURES
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.
THE UPPER TORSO RESTRAINT D-RING WHICH ATTACHES THE SHOULDER BELT TO THE B PILLAR, UNDER CERTAIN TEST CONDITIONS, SEPARATED FROM ITS ANCHORAGE, AND MAY NOT COMPLY WITH CMVSS 210 - BELT ANCHORAGE.
Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.
