Exact make, model and year evidence from official US sources. Recall campaigns, ODI investigations, complaint allegations and EPA estimates remain separate.
A campaign may cover only certain production dates, plants or equipment. A zero result here is not safety clearance. Use NHTSA’s official VIN tool for the individual vehicle.
Exact model-level NHTSA results for 1993 GMC Sonoma. Campaign records are official safety actions; applicability to a particular car still requires its VIN.

SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP
VEHICLE DESCRIPTION: CERTAIN 4-WHEEL DRIVE PICKUP TRUCKS AND SPORT UTILITY VEHICLES EQUIPPED WITH ABS (ANTILOCK BRAKING SYSTEM) MANUFACTURED FROM SEPTEMBER 1989 THROUGH AUGUST 1996. UNDER CERTAIN DRIVING CONDITIONS THE SWITCH WHICH SIGNALS THE ABS SYSTEM WHETHER THE VEHICLE IS IN 2-WHEEL OR 4-WHEEL DRIVE CAN MALFUNCTION CAUSING INCREASED STOPPING DISTANCES DURING ABS STOPS WHILE IN THE TWO-WHEEL DRIVE MODE.
Consequence
IF THIS OCCURRED AT A TIME WHEN MINIMUM STOPPING DISTANCE WAS REQUIRED, A VEHICLE CRASH COULD OCCUR WITHOUT PRIOR WARNING.
Remedy
DEALERS WILL REPLACE OR REPAIR THE 4-WHEEL/2-WHEEL DRIVE SWITCH.
SIGNIFICANT WEAR CAN DEVELOP ON THE LOW AND REVERSE CLUTCH PREVENTING THE PARK PAWL FROM ENGAGING. THIS CAN PREVENT A "NO PARK" CONDITION TO OCCUR WHILE THE ENGINE IS RUNNING, CAUSING UNINTENTIONAL MOVEMENT OF THE VEHICLE WITHOUT OPERATOR ACTION. (THE "NO PARK" CONDITION WILL NOT OCCUR WHILE THE ENGINE IS OFF.)
Consequence
UNINTENTIONAL VEHICLE MOVEMENT COULD RESULT IN A VEHICLE ACCIDENT AND INJURY TO PERSONS IN THE PATH OF THE VEHICLE.
Remedy
DEALERS WILL CHECK THE TRANSMISSION FLUID FOR CONTAMINATION WHICH WILL INDICATE IF THE LOW OR REVERSE CLUTCH IS WORN. IF THE TRANSMISSION FLUID SHOWS CONTAMINATION, THE TRANSMISSION WILL BE REPLACED.

Complaints across nearby GMC Sonoma model years
Totals for the same nameplate, scaled against its highest year here. They are not adjusted for how many were sold, how old they are, how far they are driven, or how much publicity a fault received — an older or better-selling year will usually carry more reports. This shows where the reporting sits, not which year is better.
An investigation means ODI reviewed a possible safety issue for this exact model-year identity. Opening one is not a defect finding; closing one does not by itself clear a vehicle.

The canonical URL is this file’s permanent public identifier. Source IDs and timestamps show exactly what was matched and when; they do not turn the evidence into a verdict.
Only NHTSA vPIC, NHTSA ODI complaints and investigations, NHTSA recalls and FuelEconomy.gov contribute to this vehicle claim. CPSC equipment notices are searched separately and never joined to vehicle fitment. UK MOT, Canadian, New Zealand and European records are not merged into this US claim.
