2004 Chevrolet Corvette Problems

What owners report

Owners of this model year most often report a gasoline smell or visible fuel leak, usually at the driver-side tank or the crossover tube between the two tanks, and often first noticed after a fill-up with the car parked in a garage. A second common theme in the complaints is the electronic steering column lock, where the wheel can stay locked or the car stalls with a service column message. Most complaints fall well under 60,000 miles, and many owners describe the fuel leak as appearing gradually and worsening over time.

1. 1
   Fuel system

   Fuel smell and leak at driver-side tank / crossover tube

   • 143 complaints (66%)
   • median 34,000 mi at 6.8 yrs old (120 state mileage)
   • owner-quoted repair $2,083 (median of 25 quotes)
   • filed 2004–2024

   Owners describe a strong gasoline odor in and around the car, often most noticeable in a closed garage, followed by a visible puddle or drip under the driver-side rear area. The smell typically appears after refueling, and several report the car can only be filled partway before the odor and leaking start. Dealers and mechanics commonly diagnosed a cracked or leaking driver-side fuel tank, the crossover pipe between the tanks, or its connector fitting, and in many cases replaced the tank, the crossover tube, or the fuel pump seals at the owner's expense. Mostly reported between roughly 5,000 and 70,000 miles, usually after refueling or while parked.

   What to check: Ask whether the tanks, crossover tube or connectors have been replaced, and request paperwork. After a full fill-up, check the ground under the driver-side rear for drips and smell for fuel in the cabin and garage.

   “Purchases 2004 Corvette. When I filled up gas tank, fuel odor was evident. The gas smell filled my garage and went into the house. I took to Chevrolet dealer, who said that a smoke test showed a fuel leak near where the tank is located. A more detailed diagnosis would cost about $1000, and any work would be added to that.”

   NHTSA complaint #10331677, filed 2010-05, 25,850 miles

   “I kept getting strong fuel odors in my garage but never could locate the leak. I went to fill up and gas ran down the pavement on the driver side. I took the car to the dealership and they informed me that the fuel tank had a crack in at and it spilled when I filled up directly over the exhaust pipe. The tank was replaced with a new one. The old tank was left at the dealership.”

   Steering

   Electronic column lock: wheel locks or car stalls

   • 32 complaints (15%)
   • median 30,000 mi at 9.7 yrs old (24 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2004–2024

   Complaints describe the steering wheel locking or becoming very hard to turn, sometimes while driving at low speed and sometimes while starting the car. Several owners report a service column lock or pull-key-and-wait message, or the engine shutting off shortly after moving away. Some say a dealer told them their VIN was not covered by the related column-lock campaign, and repairs such as a new steering column or relay switch were done at owner cost; others report the symptom returned after the campaign work. Spread from very low mileage (a few thousand) up to about 90,000 miles, with many reports in the 20,000 to 75,000 range.

   Recall 04V0600002 related service bulletins

   What to check: Ask whether the column-lock campaign work was ever performed on this VIN and whether any column or relay repairs followed. On a test drive, confirm the wheel turns freely after starting from lock and that no service column message appears.

   “The vehicle's electronic column locking system was having intermittent severe failure. When trying to steer the car after ignition and moving down the road the wheel would lock in certain positions and to prevent a crash I would have to stop the car and hope the locking system released. I found that this issue was covered by #04006c product safety recall. When I contacted the service department at nucar Chevrolet; they indicated that the recall was not still open. …”

   NHTSA complaint #10898943, filed 2016-08, 61,000 miles

   “The contact owns a 2004 Chevrolet Corvette. While driving approximately 30 MPH, the contact noticed that the service active handling system warning light illuminated and the steering wheel became difficult to maneuver. The vehicle was taken to the dealer for diagnostic testing. The technician stated that the yaw rate sensor in the center console would have to be replaced. …”

   Electronic stability control

   Active handling warning with a pull or brake grab

   • 26 complaints (12%)
   • median 40,929 mi at 9.5 yrs old (21 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2005–2022

   Owners describe the service active handling message appearing on the dash, sometimes followed by the car veering or pulling hard to one side, or a brief brake application. Several mention it happening at highway speed on straight roads, and a few connect it to using the telescoping steering wheel feature. Reported diagnoses include the yaw rate sensor in the center console; some owners say the electronic brake control module was unavailable or discontinued and could not be repaired. Mostly reported between about 14,000 and 76,000 miles, often at highway speeds.

   1 related service bulletin

   What to check: Test drive at highway speed and watch for the active handling message; ask whether the yaw sensor or brake control module has ever been replaced, and confirm parts availability before buying.

   “The ebcm does not work I've tried to have it repaired 3 times now told unrepairable GM no longer makes the part with so many vette owners having this problem you would wonder why there isn't something being done cause now we are driving vehicle not the way it was intended spoke to GM many times pretty told discontinued sorry too bad your on your own”

   NHTSA complaint #11288152, filed 2019-12, 17,400 miles

   “While traveling down the freeway at around 80 MPH on a straight flat surface, the Corvette sharply veered to the side as I heard a loud screech from one of the brakes it lasted for about a second. The turn was so abrupt I thought I was going to roll but after fishtailing was able to get things going straight. Immediately a service active handling system message popped up. Happened about a week later going about 60 MPH not quite as abrupt. This condition could have lead to a fatality.”

   Fuel system

   Fuel pump failure and stalling

   • 23 complaints (11%)
   • median 21,441 mi at 6.8 yrs old (16 state mileage)
   • filed 2004–2023

   A few complaints describe the engine quitting without warning while driving, including at highway speed, with the car coasting to a stop. In these reports the dealer replaced the in-tank fuel pump, and in one case a relay was also found faulty after the pumps had been replaced. Reported between roughly 21,000 and 25,000 miles in the sampled complaints.

   What to check: Ask whether the fuel pump or relay has been replaced and whether the car has ever stalled; have a pre-purchase inspection listen for a weak priming sound and check for fuel odor near the tanks.

   Electrical system

   Headlights and power window failures

   • 6 complaints (3%)
   • median 36,000 mi at 4.9 yrs old (6 state mileage, few)
   • filed 2007–2017

   Owners report electrical items failing, including headlights that went out completely while driving at night and would not come back on for several minutes. Others describe power window regulators failing repeatedly, with the window not moving or the cable fraying and the window dropping partway; regulators were replaced more than once at notable cost. Reported from about 20,000 to 82,000 miles in the sampled complaints.

   2 related service bulletins

   What to check: Cycle every window up and down and check for slow or uneven movement, and test the headlights, including high beams, on a dark test drive. Ask whether any regulators or lighting components have already been replaced.

   “Our Corvette convertible had a rattle in the back we id as the back window from the convertible top had become separated from the adhesive and fell out into the back of the car. This seems to be a problem that is being handled through the recall.”

   NHTSA complaint #10297358, filed 2009-12, 30,000 miles

   “2004 Chevrolet Corvette power window regulators keep failing. Window will either not roll down at all, or sometimes the regulator cable will fray and window will partially go down. I have had two regulators on the passenger side and the current one no longer works. And I have just installed the third one on the driver side. This car only has 48,000 mile on it and it is babied. Yet these parts keep failing and the repair cost is $550.00 per incident. …”

   NHTSA complaint #10420777, filed 2011-08, 20,000 miles

Buying note. A pre-purchase inspection should focus on the fuel system, since a fuel smell or drip after a full tank is the most common complaint for this model year and repairs can be expensive. Also confirm whether the steering column-lock campaign was applied to the specific VIN and check the windows, lights and active handling system on a test drive.
