* Rear Differential Issues: A common problem was premature wear and failure of the rear differential. This could manifest as whining noises, leaks, or complete failure. Regular maintenance and using the correct type of gear oil are crucial to mitigating this.
* Electrical Problems: Like many cars of the era, the 1999 Corvette could suffer from various electrical gremlins. This could include problems with the radio, power windows, or other electrical components. Often these were related to wiring harness issues or faulty connectors.
* ABS System Problems: Issues with the Anti-lock Braking System (ABS) were reported, potentially resulting in warning lights or malfunctioning ABS. This could be due to sensor problems or module failures.
* Transmission Problems: While not as common as the differential issues, some owners experienced problems with the automatic transmission, including rough shifting or slipping.
* Head Gasket Leaks (Less Common, but Significant): While not overwhelmingly common, head gasket leaks were a potential concern, particularly in higher-mileage vehicles. This is a major repair.
* Exhaust Manifold Cracking: Cracking of the exhaust manifolds could lead to exhaust leaks and noises.
* Steering Rack Problems: Some reports mention steering rack issues, possibly resulting in play or leaks.
* Cooling System Issues: Problems with the cooling system, such as leaks or radiator issues, could occur, especially with age and lack of proper maintenance.
Important Note: The frequency of these problems can vary depending on maintenance history, driving habits, and overall vehicle care. A well-maintained 1999 Corvette is likely to be more reliable than one that has been neglected. Pre-purchase inspections are highly recommended when buying a used C5 Corvette.
