Vauxhall Insignia Mk2

The second-generation Vauxhall Insignia (2017–2024), marketed as the Insignia Grand Sport and Sports Tourer, marked a significant departure from its predecessor by focusing on reduced weight, improved interior packaging, and a much-refined driving experience. It feels more agile and premium than the first-generation Insignia, establishing itself as a sophisticated contender in the dwindling executive saloon market. However, like many modern vehicles, its increased reliance on complex electronic interfaces and advanced emissions hardware means that prospective buyers must be discerning, as deferred maintenance can quickly turn a premium-feeling car into a costly liability. Under the bonnet, the Insignia Mk2 utilizes a range of engines that require specific maintenance attention. The 1.5-litre petrol engines, while efficient, have been known to exhibit timing-chain issues if oil-service intervals are not strictly adhered to, making a verified service history a non-negotiable requirement. For diesel variants, which remain popular for high-mileage users, the emissions hardware—including NOx sensors and AdBlue systems—is a common point of contention. Buyers should be aware that these systems are sensitive to driving patterns; vehicles that have spent most of their lives doing short, urban trips are disproportionately likely to trigger emissions warning lights and enter restricted performance modes. Inside, the Insignia Mk2 is heavily digitized, with a sophisticated infotainment system, reversing cameras, and, on higher trim levels, electric tailgate functionality. While impressive, these systems can be susceptible to software glitches, including screen freezing and sluggish responses, which are particularly prevalent on earlier production years. Furthermore, the electric tailgate, while a useful luxury, can become a source of frustration if the spindle or motor mechanism fails. A successful purchase of a used Insignia Mk2 relies heavily on finding a well-documented example that has been used primarily for the long-distance motorway driving it was designed for, rather than stop-start urban commuting.
