Stalling on other Terrain years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2016, 2017, 2026.
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
Few of these reports name the part that was replaced.
Recalls and investigations
No recall on the engine covers the 2015 model year as of Oct 2, 2026.
What owners paid
5 of the 40 reports quote a price. Each dot is one quote. The middle half runs $1,648 to $5,000.
When it happens
The middle half of failures fell between 44,000 and 120,000 miles, from the 22 reports that gave a mileage.

Should you keep driving it?
This page can't tell you that. 0 of 40 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.
