Alfa Romeo used to have a reputation for producing cars that were notoriously unreliable. While their reputation has improved significantly over the years, like any other manufacturer their cars still aren't immune to safety recalls. Being a 500-hp beast of an SUV, there's no doubt that the 2.9-liter twin-turbo V6 powering the Alfa Romeo Stelvio Quadrifoglio is worked hard, but a recently discovered defect could cause it to get too hot.

According to the National Highway Traffic Safety Administration, a leaking coolant hose could cause the engine to overheat and possibly stall. Insufficient webbing on a coolant hose is being cited as the root of the problem. Luckily, only 674 vehicles are affected in the US. Owners will need to arrange a visit to their local dealer to have a new hose fitted.

Unfortunately, a larger number of Stelvio crossovers and Giulia sedans equipped with the smaller 2.0-liter engine are being recalled for a separate heat-related issue. This time, an engine misfire could cause the catalytic converter to overheat and potentially start a fire. If it overheats, drivers may notice an illuminated check-engine light on the dashboard, temporary engine power loss, or, "in extreme cases," a burning smell.

In the US, 37,228 examples are being recalled as a result of the issue. The automaker is aware of two engine compartment fires that may be related to the issue but is not aware of any other incidents or injuries. To fix the issue, dealers will update the engine-control software of affected vehicles free of charge. Less than one percent of the recalled vehicles will need a new catalytic converter according to the automaker.
