Alfa Romeo is recalling 34,359 of its 2017 to 2018 Giulia sedans and 2018 Stelvio SUVs because their catalytic converters may overheat. This could cause the vehicles to stall or even catch fire.
The catalytic converter is part of the car's exhaust system that helps to reduce a vehicle's emissions.
If the overheating occurs, drivers may notice an illuminated check-engine light on the dashboard, temporary engine power loss, or—"in extreme cases," the automaker says—a burning smell. An Alfa Romeo spokesperson told CR that the issue is caused by an engine misfire.
The automaker said it is aware of two engine-compartment fires that are potentially related to the issue but said it's not aware of any other incidents or any injuries.

The Details
Vehicles recalled: Certain 2017 to 2018 Alfa Romeo Giulia sedans and 2018 Alfa Romeo Stelvio SUVs. High-performance Quadrifoglio models are not affected, the automaker says.
The problem: A condition that the automaker says happens "rarely and is imperceptible to the driver" could cause the catalytic converter to overheat, the automaker said. If that happens, the vehicle may stall or, "in unique circumstances," catch fire.
The fix: Dealers will update the engine-control software of affected vehicles. Fewer than 1 percent of the recalled vehicles will need a new catalytic converter, the automaker said. The work will be done at no charge to owners.
How to contact the manufacturer: An Alfa Romeo spokesperson told CR that recall notices would be sent to owners in early October. Owners of affected vehicles can also call Alfa Romeo at 866-932-3881.
NHTSA campaign number: NHTSA has not yet issued a number for this recall.
