Limited data — recalls on file
NHTSA has just 6 complaints on file for the 1994 GMC S15 — too few to judge reliability from owner reports alone — but 2 recall campaigns apply to this year, so any used example should have its VIN checked for completed recall work.

2 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
A VACUUM HOSE CAN DETACH FROM THE POWER BRAKE BOOSTER CHECK VALVE AS A RESULT OF ENGINE BACKFIRE.
Consequence
THIS CAN RESULT IN INCREASED ENGINE IDLE AND LOSS OF POWER BRAKE ASSIST AFTER DEPLETION OF THE BOOSTER VACUUM RESERVE.
Remedy
DEALERS WILL INSTALL A CLAMP ON THE POWER BRAKE BOOSTER ASSIST.
Defect
THE FUEL TANK FILLER PIPES WERE NOT MANUFACTURED TO SPECIFICATION WHICH CAUSED LOSS OF FUEL BETWEEN THE FUEL TANK FILLER PIPE AND THE VENT TUBE DURING A TEST. THE LOSS OF FUEL WAS IN EXCESS OF THE AMOUNT PERMITTED BY FMVSS NO. 301, "FUEL SYSTEM INTEGRITY."
Consequence
CONSEQUENCE OF NON-COMPLIANCE: IF A VEHICLE CRASH WERE TO OCCUR, IT MAY CAUSE THE JOINT BETWEEN THE FUEL TANK FILLER PIPES AND THE VENT TUBE TO CRACK. IF THE VEHICLE OVERTURNED, FUEL LEAKAGE WOULD OCCUR, WHICH COULD RESULT IN A POST-CRASH FIRE.
Remedy
DEALERS WILL REPLACE THE FUEL FILLER PIPE ON THESE VEHICLES.

“WHEN APPLIED THE ABS BRAKES ON DRY PAVEMENT THE PEDAL TRAVELED TO THE FLOOR, CAUSING EXTENDED STOPPING DISTANCE WHICH RESULTED IN A COLLISION. PLEASE GIVE ANY FURTHER DETAILS. *AK ”
“FUEL TANK LEAKING AROUND SEAM. HAS THERE BEEN ANY RECALLS ON THIS PROBLEM? MANY PEOPLE THAT HAVE THIS YEAR GMC JIMMY HAS HAD THE SAME PROBLEM.*AK”
“WINDSHIELD WIPERS FAIL INTERMITTENTLY, WIPER MOTOR MODULE REPLACED. SOME CHEVROLET VEHICLES HAVE BEEN RECALLED FOR THIS PROBLEM (98V-150)”
The record is thin — 6 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 2 recalls should be verified as completed.
Yes — NHTSA lists 2 recall campaigns affecting the 1994 GMC S15. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
