Summary Verdict

The 2007 Mercury Montego is a generally reliable vehicle, but like many cars of its era, it can experience specific issues. The 3.0L V6 engine may encounter cooling system leaks or VVT problems. The 6-speed automatic transmission can sometimes exhibit hesitation or require TCM replacement. Suspension components like struts and ball joints are common wear items that may need attention. Electrical gremlins, particularly with window regulators and instrument clusters, are also noted. Interior issues are less common, with HVAC blower motors being a potential concern. Regular maintenance and addressing these potential issues promptly can help ensure the longevity of the Montego.
