What are the most common problems with the 1985 Rolls-Royce Silver Spirit?

Question

Accepted Answer

Based on my research and the specific vehicle details, here are the most common problems with the 1985 Rolls-Royce Silver Spirit:

**1. Hydraulic Brake System Issues (Most Critical)**
- Brake accumulator sphere failure - This is the #1 issue. The nitrogen-filled spheres degrade over time, causing brake warning lights and potential brake failure
- Expensive to replace (around $500-800 per sphere, and there are multiple spheres)
- Symptoms: brake pedal becomes hard, warning lights come on after braking

**2. Electrical System Problems**
- Power seat failures (as seen in this vehicle - passenger seat not working)
- Lighting issues (as seen - left high beam and side light not working)
- High-beam switch failure (as seen in this car)
- Dashboard electrical gremlins are common

**3. Suspension Issues**
- Play in suspension joints (as noted in this vehicle)
- Rear wheel bearing play (also noted)
- The complex hydraulic suspension system can develop leaks

**4. Engine Oil Leaks**
- Multiple oil leak points are common:
  - Steering box leaks (as seen in this vehicle)
  - Gearbox oil cooler leaks (also seen)
  - Valve cover gaskets
  - Oil pan gaskets

**5. Age-Related Issues**
- Dried out tires requiring replacement (as seen)
- Superficial corrosion on underside
- Interior wear on carpets and upholstery

**6. Maintenance-Intensive Systems**
- The 6.75L V8 engine requires regular maintenance
- Automatic transmission needs periodic service
- Air conditioning systems are problematic
- Cold start issues in cooler weather

**What makes the 1985 model challenging:**
- Parts are expensive and sometimes hard to find
- Requires specialist knowledge for repairs
- Many systems are unique to Rolls-Royce and not shared with other brands
- Labor costs are high due to complexity

The good news is that most of these issues are well-documented, and there are specialists who know these cars well. The hydraulic brake system should be your biggest concern - make sure it's properly inspected before purchase.
