2004 Chevrolet Corvette Recalls (Recent)

Suspension & Steering, April 26, 2004

Summary: 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 .

Suspension & Steering, August 25, 2004

RepairPal Expert Overview:

The washer for the control arm ball stud may have been made of the wrong material, and may fracture and fall out, or become loose. The control arm may separate from the steering knuckle due to disengagement of the tapered stud, causing the vehicle to drop at that corner. In extreme situations, the wheel may separate completely from the vehicle. Either condition would impair handling and increase the chances of a crash. Dealers will inspect the torque on the ball stud joints on all front and rear lower control arms. If the torque is not to specification, the ball stud, knuckle, and nut will be replaced. If the torque is to specification, the dealers will replace only the ball stud nut and washer. The recall began August 24, 2004. The GM recall number is 04043.

2004 Chevrolet Corvette Reviews

This is my 5th Corvette and my next car will also be a Corvette. Sooo much fun to drive.. Ladies: it will make you happy every time you drive it, it does exactly what you want it to do when you want it to, and nothing bad happens that a little money won't fix. How many guys can you say that about?

I got it three years ago. I just always wanted one. I debated between the 2004 and 2005. but chose the '04, last year for pop-up lights and only 16000 miles on it. Car is a dream to drive. Was going to put twin turbos on it after I got smoked by a viper, but figured I'd keep it original and just cruise.

Best car ever............
