Recall history
1 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
95V103004 · Seat Belts:Front:Buckle Assembly
Reported: 1995-05-24 (May 24, 1995)
THE FRONT SAFETY BELT BUCKLE RELEASE BUTTONS CAN BREAK. THESE RED PLASTIC RELEASE BUTTONS ARE MARKED "PRESS." IF A BUTTON BREAKS, PIECES CAN FALL INTO THE BUCKLE ASSEMBLY CAUSING THE BUCKLE TO OPERATE IMPROPERLY.
Consequence: THE SAFETY BELTS WOULD NOT PROVIDE ADEQUATE PROTECTION TO AN OCCUPANT IN A VEHICLE CRASH.
Remedy: OWNERS SHOULD PROMPTLY CHECK THE CONDITION AND OPERATION OF BOTH FRONT SAFETY BELT BUCKLES AND CAREFULLY INSPECT THE RED RELEASE BUTTON FOR ANY BREAKS OR CRACKS. THEY SHOULD ENSURE THAT BOTH BUCKLES ARE OPERATING PROPERLY BY INSERTING EACH LATCH PLATE INTO ITS BUCKLE, TUGGING ON THE BELT TO MAKE SURE THE LATCH IS SECURELY LOCKED, AND THEN PRESSING THE RELEASE BUTTON. THE LATCH PLATE SHOULD POP OUT OF THE BUCKLE WHEN THE BUTTON IS PRESSED. IF EITHER RELEASE BUTTON SHOWS A SIGN OF BREAKING OR CRACKING OR IF EITHER BUCKLE FAILS TO OPERATE PROPERLY, OWNERS SHOULD PROMPTLY CONTACT THEIR AUTHORIZED DEALER TO SCHEDULE AN APPOINTMENT TO HAVE THE BUCKLE REPLACED OR REPAIRED, FREE OF CHARGE. THE MANUFACTURER IS DEVELOPING A REMEDY DESIGNED TO PREVENT FAILURE OF THE BUTTONS THAT ARE NOT CURRENTLY BROKEN.

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.
1989: 0 complaints · 1990: 0 complaints
| Model year | Through age 0 | Through age 1 | Through age 2 |
|---|---|---|---|
| 1989 | 0 | 0 | 0 |
| 1990 | 0 | 0 | 0 |
Date coverage across each selected cohort
| Year | Incident dates used | Filing date fallbacks | Excluded dates |
|---|---|---|---|
| 1989 | 1 | 0 | 0 |
| 1990 | 1 | 1 | 0 |
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.
