4 safety recalls, most serious first

THE FUEL RETURN LINE HAS A MECHANICAL BLEED VALVE WHICH WAS NOT INSTALLED AT THE PROPER TORQUE.
What could happen: A FUEL LEAK CAN OCCUR AT THE VALVE, POSSIBLY RESULTING IN A FIRE.
The fix: R&B, INC. WILL NOTIFY OWNERS AND AT THE CUSTOMERS REQUEST, EITHER REPLACE THE FUEL LINE OR OFFER A FULL REFUND. THE RECALL BEGAN ON MAY 4, 2006. OWNERS MAY CONTACT R&B, INC. AT 215-712-5330.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 1993 SONOMA.
- Book a repair at any authorized GMC dealer. Quote NHTSA campaign 06E041000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

3. Brakes

4. Transmission / drivetrain
What's wrong, in plain English: The parts that send engine power to the wheels. Failure can mean a sudden loss of power or the car rolling away. 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.)
What could happen: UNINTENTIONAL VEHICLE MOVEMENT COULD RESULT IN A VEHICLE ACCIDENT AND INJURY TO PERSONS IN THE PATH OF THE VEHICLE.
The fix: 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.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 1993 SONOMA.
