* Electrical Issues: This is probably the *most* common complaint. The complex electrical system, including the climate control, power seats, windows, and various sensors, was prone to failure. Wires could chafe, connectors corrode, and modules fail, leading to intermittent or complete malfunctions. Diagnosing these issues could be extremely difficult.
* Transmission Problems: The 4T60-E automatic transmission was known for its unreliability. Common problems included slipping, rough shifting, and premature failure. This was a widely known issue across several GM vehicles of that era, not just the Riviera.
* Cooling System Issues: Leaks in hoses, radiators, and water pumps were relatively frequent. This could lead to overheating and potentially significant engine damage if not addressed promptly.
* Suspension and Steering Components: Wear and tear on bushings, ball joints, and tie rod ends were common, leading to handling issues and noise. This is less specific to the Riviera and more a general issue with older cars.
* ABS System Issues: The Anti-lock Braking System (ABS) could malfunction, leading to warning lights and potentially compromised braking performance.
* Oxygen Sensor Issues: These sensors are crucial for proper engine operation and fuel efficiency. Failure could lead to poor performance, rough idle, and potentially damage to the catalytic converter.
* Engine Problems: While generally reliable, the Northstar V8 engine (if equipped) wasn't immune to issues. Potential problems included valve cover leaks, camshaft sensor issues, and occasional head gasket problems (though less common than in some other engines).
It's important to note that the severity and frequency of these problems varied depending on maintenance history and driving conditions. A well-maintained 1995 Riviera is likely to be more reliable than one neglected. However, the inherent complexities and known weaknesses of certain components make preventative maintenance and thorough inspections crucial for potential buyers.
