1987 GMC School Bus Series Recalls
Safety recall campaigns filed with NHTSA that cover this model year
Recalls apply to specific vehicles, not to every vehicle of a model year. Check your VIN with NHTSA or your manufacturer's dealer to confirm whether a recall affects your vehicle.
Check a VIN on NHTSA.govRecall campaignsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
0
Carrying an NHTSA advisoryCampaigns where NHTSA told owners not to drive the vehicle, or to park it outside, until the repair is done.
0
Open investigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

Recall campaigns
No recall campaigns in our database for this model year
This does not guarantee that a specific vehicle is unaffected. Recalls are issued against ranges of VINs rather than against a whole model year, new campaigns are announced regularly, and a manufacturer may have opened one since our last refresh. The authoritative answer for one vehicle is NHTSA’s own lookup — check a VIN on NHTSA.gov.
What a recall is
- Safety recall
- A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
- Safety investigation
- NHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
- Manufacturer communication
- Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
Safety investigations
NHTSA inquiries naming this vehicle. An investigation is not a finding of a defect, and it is not a recall.
