HE DID NOT TELL ME THERE WAS ANYTHING WRONG WITH THE CAR WHEN I BOUGHT IT. NO SAFETY DEFECT LISTED IN THE SUMMARY. *AK

Recall history
1 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
87V071000 · Fuel System, Gasoline:Delivery:Fuel Pump
Reported: 1987-05-27 (May 27, 1987)
VEHICLE MAY EXPERIENCE PERFORATION OF THE FUEL PUMP DIAPHRAGM. EXCESSIVE ALCOHOL CONTENT IN THE FUEL PROMOTES DEGRADATION OF THE DIAPHRAGM COATING RESULTING IN RADIAL CRACKING OF THE DIAPHRAGM.
Consequence: A PERFORATED DIAPHRAGM CAN ALLOW FUEL TO LEAK FROM THEFUEL PUMP INTO THE UNDERHOOD AREA. THIS COULD ULTIMATELY RESULT IN ANUNDERHOOD FIRE WITHOUT PRIOR WARNING. SUCH A FIRE COULD SPREAD TO THEPASSENGER COMPARTMENT.
Remedy: A FUEL VENTALATION HOSE KIT WILL BE INSTALLED TO PREVENT FUEL FROM ESCAPING INTO THE ENGINE COMPARTMENT IF THE FUEL PUMP DIAPHRAGM LEAKS AND THEREBY REDUCE THE POSSIBILITY OF AN UNDERHOOD FIRE.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
1988: 0 complaints · 1989: 1 complaints
| Model year | Through age 0 | Through age 1 | Through age 2 |

Incident date is preferred when valid and no later than filing; otherwise filing date is used. Model year approximates age. Equal observation time does not adjust for sales, distance driven or reporting delays. One complaint linked to multiple model years can appear in each cohort.
