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 2014 model year as of Oct 2, 2026.
What owners paid
7 of the 49 reports quote a price. Each dot is one quote. The middle half runs $2,200 to $6,700.
When it happens
The middle half of failures fell between 50,249 and 105,000 miles, from the 37 reports that gave a mileage.
Is this a known problem?

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.

“Tensioner issues keeps breaking the timing chain. . Replaced twice at own cost. Fuel pump/ loss of power while driving. Back up camera doesn't work sometimes. Screen goes black. If key is left in the ignition it starts itself. If you try to use a car charger for a phone the AC shuts off and a "systems error" message pops up. This happens alot. It's an ongoing issue since I bought the car in Feburary this year.”

“I have had the same oil consumption and car stalling problems as everyone else. When the oil gets low after a few hundred miles, it stalls out when starting from a stopped position. It goes through a quart of oil at less than 1,000 miles. Add me to the list that says they need to recall the 2014 Terrains since they have the same problem as the 2011 to 2013 Terrains that were recalled.”

Should you keep driving it?
This page can't tell you that. 0 of 49 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.
