When owners complained

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.

Recalls on the 2002 Cadillac STS

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 certain Aurora, Bonneville SSEi, Devile and STS vehicles, the fuel tank pressure sensor is unusually susceptible to malfunctions causing excessive vacuum to be applied during self-diagnostic testing. Fuel system components can be damaged and fuel can leak from the vehicle when it is refueled. Possible symptoms of this condition are illumination of the Service Engine Soon light, poor driveability, increase noise from the fuel tank area, and inaccurate fuel gauge readings. If there is an ignition source present, a fire could result. Correction: Dealer will replace the fuel tank pressure sensor.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.
