On the 1997-2004 Chevrolet Corvette, the C5 Corvette has a notorious electronic steering column lock (part of the Vehicle Anti-Theft System / VATS) that fails, preventing the car from starting. When the column lock module fails, the car displays "SERVICE COLUMN LOCK" and refuses to start even with the correct key. The column lock motor or position sensor fails, and GM designed it as a security feature that defaults to locked when it fails. This can strand you anywhere. It is the #1 most-discussed C5 reliability issue.
The permanent fix is to bypass or disable the column lock. Delphi (OEM supplier) sells a bypass module that plugs into the column lock connector and eliminates the lock function while keeping the anti-theft system working. Many C5 owners bypass the column lock preemptively before it fails. GM dealers can also reprogram the BCM to disable the column lock. A failed column lock module can be replaced but the new one will eventually fail too.

On the 1997-2004 Chevrolet Corvette, the C5 Corvette LS1 and LS6 engines have a known harmonic balancer (crankshaft pulley) failure. The rubber bonding between the inner hub and outer ring separates, causing the outer ring to wobble or walk off the crankshaft. This can destroy the serpentine belt, damage the timing cover, and in severe cases score the crankshaft snout. The issue typically occurs between 80,000-150,000 miles. A wobbling harmonic balancer also throws off ignition timing and can cause engine damage.
Replace the harmonic balancer. ATI Super Damper is the definitive upgrade - it uses elastomer O-rings instead of bonded rubber, making it essentially lifetime. The GM replacement balancer will eventually fail the same way. Installation requires a balancer puller and installer tool. While the balancer is off, replace the front crank seal.

STEERING:LINKAGES
ON CERTAIN PASSENGER VEHICLES INVOLVED IN THIS CAMPAIGN, THE LOWER CONTROL ARM BALL STUD NUT/WASHER ASSEMBLIES WITH WASHERS WERE MADE OF THE WRONG MATERIAL. THE WASHERS MAY FRACTURE AND BECOME LOOSE OR FALL AWAY FROM THE VEHICLE, REDUCING CLAMP LOAD. SEPARATION OF THE CONTROL ARM BALL STUD AND STEERING KNUCKLE, DUE TO DISENGAGEMENT OF THE TAPERED ATTACHMENT AND RETAINING NUT, IS POSSIBLE.
STEERING:COLUMN LOCKING:ANTI-THEFT DEVICE
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH ELECTRONIC COLUMN LOCK SYSTEMS (ECL), WHEN THE IGNITION SWITCH IS TURNED TO "LOCK," THE ECL SYSTEM PREVENTS TURNING OF THE STEERING SYSTEM. WHEN THE VEHICLE IS STARTED, THE ECL UNLOCKS THE STEERING SYSTEM. THE VEHICLE IS DESIGNED SO THAT IF THE COLUMN FAILS TO UNLOCK WHEN THE VEHICLE IS STARTED AND THE CUSTOMER TRIES TO DRIVE, THE FUEL SUPPLY WILL BE SHUT OFF SO THAT THE VEHICLE CANNOT MOVE WHEN THE VEHICLE CANNOT BE STEERED. IF VOLTAGE AT THE POWERTRAIN CONTROL MODULE IS LOW OR INTERRUPTED, HOWEVER, THE FUEL SHUT OFF MAY NOT OCCUR AND THE VEHICLE CAN BE ACCELERATED WHILE THE STEERING SYSTEM IS LOCKED. ALSO WHEN THE CONTROL SYSTEM SHOWS THAT THE ECL IS UNLOCKED AND THE VEHICLE IS BEING DRIVEN, THE LOCK PIN LOCATION CAN VARY. DEPENDING ON THE LOCATION OF THE LOCK PLATE RELATIVE TO THE SWITCH TRANSITION POINT, THERE COULD THEN BE CONTACT BETWEEN THE LOCK PLATE AND PIN CAUSING THE STEERING TO LOCK WHILE DRIVING .
