Summary Verdict

The 2006 Lincoln LS offers a comfortable and relatively powerful driving experience, particularly with the V8 option. However, potential buyers should be aware of common issues. The V8 engine’s timing chain tensioners are a significant concern that can lead to costly repairs if not addressed proactively. Both engines can suffer from intake manifold gasket leaks and sensor failures. Transmission issues, primarily fluid leaks and solenoid problems, are also reported. On the electrical front, window regulators and instrument clusters can be problematic. Exterior paint, specifically clear coat, may show signs of degradation. Interior comfort features like seat heaters and HVAC components can also develop faults. Despite these potential drawbacks, many LS models have proven reliable with proper maintenance and timely repairs of known issues.
