Stalling on other Stelvio years
No other Stelvio model year has enough reports of stalling for a sheet of its own. See every Stelvio year.
What this problem usually is
Stalling reports are some of the most alarming on the site. The engine quits while the car is moving, sometimes on a highway and sometimes at a stop. Many owners say it restarted right away and the dealer found no stored code, which is part of why these complaints pile up before anything gets fixed.
What got replaced
Owners who name the part that was replaced mention the fuel pump (12 reports), the throttle body (5 reports) and the battery (4 reports).
Recalls and investigations
5 recalls on the engine cover the 2018 model year. A recall on the same system isn't always the same failure, so read the defect text.
The fuel pump may fail, which can result in a loss of fuel flow and loss of drive power.
The Body Control Module (BCM) may indicate an inaccurate fuel level that displays higher than the actual amount.
The engine cooling hose may have inadequate webbing material allowing a coolant leak.
These engines may misfire causing the catalytic converter to overheat, possibly resulting in damage to the nearby wiring and engine components.
Water may leak into the body control module and its connectors, causing corrosion.

Should you keep driving it?
This page can't tell you that. 0 of 33 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
