THE C4 CORVETTE - COMMON ISSUES
The following list of common issues is intended for individual reference only, and may not reflect the specific issues of every 1992 Corvette. This information comes from a variety of sources including the NHTSA Defects Reports pages. While the intent of this page is to identify the common issues pertaining to the 1992 Corvette, it is not an all-inclusive list and should be used for reference only.
- The engine may accelerate at anytime without warning, regardless of whether the car is gear or in reverse. The air control valve has been identified as a possible cause of this issue.
- An occasional problem on this vehicle is failure of the Opti-Spark Ignition System. Failure of the Opti-Spark Ignition System applies to (PFI V8 engines) only. Failure of the Opti-Spark Ignition System may prevent the vehicle from starting.
- The anti-lock braking system fails unexpectedly during normal driving conditions resulting in loss of vehicle control.
- A periodic problem is the failure of the Shock Absorber Actuator. Failure of the Shock Absorber Actuator applies to vehicles equipped with Selective Ride Control only.
HEATING & AIR CONDITIONING
- An occasional problem on this vehicle is failure of the Automatic Temperature Control. This vehicle was originally charged with R-12 refrigerant which is no longer being manufactured. The refrigerant is still available, but it is very expensive ($25.00-$50.00 per pound, 2-5 pounds per vehicle). Conversion to the new R-134A refrigerant is also a viable, and more cost effective, option.
ELECTRONIC CONTROL UNIT (ECU)
- The electronic control unit (ECU) is prone to failure which cause low idle or stall conditions. Failure of the ECU can also prevent the Corvette from starting.
WINDSHIELD WIPER SYSTEM
- The windshield wipers periodically skip across the windshield, which causes them to get out of sync with each other. Additionally, the wiper assembly is prone to lock up during normal usage and requires replacement of entire assembly.
PASSIVE RESTRAINT SYSTEM
- During activation in an impact situation, the airbags either failed to deploy completely, or they partially deployed without fully inflating.
SEAT BELTS/SAFETY RESTRAINTS
- In some instances, the shoulder harness of the driver's seat belt has failed to restrain driver during crash condition, causing driver to sustain injury against steering wheel/dashboard.
- The power seats wiring is known to arc and cause the seats/floor carpeting to catch fire.
- No other known issues reported at this time.
