No other Stelvio model year has enough reports of misfire for a sheet of its own. See every Stelvio year.

What this problem usually is

These reports start with the check engine light. Many describe the engine running rough or shaking at idle, a P0300-series code, or a catalytic converter code. A worrying number say the light was flashing. Owners often list ignition coils or spark plugs already replaced, and the light coming back afterward.

Is this a known problem?

The manufacturer has sent NHTSA 6 service bulletins or notices for the 2018 Alfa Romeo Stelvio that deal with this problem. Newest first.

Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

What owners wrote

“I orchard my car used, but still under warranty. Within a week it has shut down with a service engine error. I was told it was the power control module (PCM) both times. There's no logical reason, I know of for a car with only 40K miles on it to have an engine failure such as the PCM. Both times both dealerships stated that the game was coming from the solenoids and having a misfire caused by the PCM.”

Should you keep driving it?

This page can't tell you that. 0 of 25 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.
