Summary
The 2006 Cadillac XLR, while a stylish and desirable luxury roadster, has several common issues that potential buyers should be aware of. The most prevalent problems revolve around the engine (oil and coolant leaks), transmission (torque converter issues), suspension (MRC shocks), electrical system (retractable hardtop malfunctions and battery drain), and interior (infotainment failures). The severity and cost of these issues can vary greatly. While some issues, like replacing seals or sensors, may be relatively inexpensive, others, such as replacing MRC shocks or overhauling the retractable hardtop mechanism, can be quite costly. Prospective buyers should have a thorough inspection performed by a qualified mechanic before purchase to identify any existing or potential problems.
