Summary Verdict

The 2008 Cadillac XLR, while a luxurious and engaging vehicle, exhibits some common issues primarily related to its advanced systems. The 4.6L V8 engine can experience oil and coolant leaks, and the automatic transmission may develop shifting problems. The sophisticated retractable hardtop and adaptive suspension are prone to electrical and mechanical failures, respectively. Interior electrical components, such as the infotainment screen, and exterior paint quality are also areas to monitor. Despite these potential concerns, many XLRs remain reliable with proper maintenance, but owners should be prepared for potential costs associated with these specific components.
