Saab 9-5 NG Common Problems & Reliability
The New Generation Saab 9-5 is a tragic masterpiece; launched right before the company's bankruptcy, it is a stunningly beautiful, technologically advanced executive saloon based on a stretched Vauxhall Insignia platform. In the UK, it is an exceedingly rare sight, highly coveted by Saab enthusiasts for its aviation-inspired design, "wraparound" glasshouse, and Head-Up Display. Reliability of the mechanicals (shared with GM) is solid, but unique trim pieces and specific electronic modules are incredibly difficult to source. Buying one requires commitment, but it rewards the owner with immense exclusivity and comfort. It is strictly for dedicated Saab aficionados who want the ultimate, final iteration of the brand.
