When does it fail?
Of the 13 fuel system complaints filed for the 2022 GMC Terrain, here's the actual mileage breakdown — failures cluster heaviest at 25,000-50,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
Of the 4 model years of GMC Terrain we track for fuel system problems, this one carries the most owner complaints on file — 13.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering fuel system on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This service bulletin provides information for maintenance cleaning of the fuel injectors and gasoline detergent additive.

The failure pattern owners describe
Owners describe their 2022 Terrain losing power and stalling suddenly on highways and in traffic, mostly without warning lights. The engine shuts down completely and won't restart — a hazardous situation that has sent vehicles to the roadside and required towing. This happens as early as 4,800 miles and continues past 75,000 miles.
Independent mechanics and dealers consistently diagnose fuel pump module failure. One owner had the module replaced, only to see it fail again shortly after. Other owners' vehicles sit unrepaired because either they were told a fuel pump module replacement was needed but couldn't afford it, or the dealer couldn't find the problem without diagnostic codes.
Some owners experience a slower version of this: the vehicle loses momentum or decelerates on its own, sometimes with a gasoline smell in the cabin. One owner pulled a diagnostic code (P129F) with a handheld scanner when the vehicle stalled in a parking lot.
Multiple owners reference NHTSA Campaign 23V013000 (Fuel System, Gasoline), but their VINs are explicitly excluded from the recall. Others received recall notices but dealers can't perform the repair because GMC hasn't supplied the parts yet. Owners report waiting well beyond what they consider reasonable, with some saying the manufacturer deflected them to the NHTSA hotline.
Failure modes owners describe
Fuel pump module failure — stalling and loss of motive power
Engine stalls without warning during normal driving, vehicle loses all forward momentum and fails to restart. Multiple narratives report the same symptom pattern across a range of mileages, suggesting a systemic defect in the fuel pump module.
When: 4,800 to 76,670 miles; majority of failures occur before 50,000 miles
Symptoms owners cite: Engine stalls abruptly while driving; No warning lights in early stages; check engine light may illuminate after initial stall; Vehicle unable to restart; Loss of all motive power
Codes mentioned: P129F
Repairs/costs cited: Fuel pump module replacement performed by dealers in narratives #3 and #7; failed again in #3 after first replacement. Owners in narratives #1, #4, #6, #8 report diagnosis of fuel pump module failure but vehicle not repaired.
Recalls/TSBs owners mention: NHTSA Campaign Number 23V013000 (Fuel System, Gasoline) issued, but affected VINs in these narratives are explicitly stated as NOT included in recall selection. Manufacturer advised filing NHTSA complaint in narrative #6.
Fuel pump module degradation — power loss and hesitation
Vehicle loses forward momentum or decelerates during normal driving operation, engine hesitates on acceleration but does not fully stall. May be precursor to complete failure.
When: 3,600 to 49,000 miles
Symptoms owners cite: Vehicle loses forward momentum while driving; Engine hesitates when accelerator is depressed; Vehicle decelerates to 10 MPH without driver input; Gasoline odor in passenger cabin reported in one case
Repairs/costs cited: No repairs documented in narratives reporting this symptom. Dealer unable to diagnose in narrative #2 due to no diagnostic codes in system.
Recalls/TSBs owners mention: NHTSA Campaign Number 23V013000 referenced in narrative #2; VIN not included in recall.
Recall part unavailability — unresolved fuel pump module replacement
Owners receive recall notice for Campaign 23V013000 but repair cannot be performed because replacement parts are unavailable for extended period. Owners report manufacturer exceeding reasonable timeframe for providing parts.
When: As of complaint filing; failures noted at 3,600 and 7,000 miles prior to part availability
Symptoms owners cite: Recall issued but parts not available; Vehicle loss of motive power or deceleration occurs while awaiting repair
Repairs/costs cited: Repair not performed; parts unavailable. VIN tool confirms parts not available for narratives #9, #10, #12.
Recalls/TSBs owners mention: NHTSA Campaign Number 23V013000 issued; parts confirmed unavailable per VIN tool.

Common questions
How serious is the fuel system problem on the 2022 GMC Terrain?
It's a documented issue but not catastrophic. 13 complaints have been filed. Repairs average $1,200 and most owners catch it before it causes a breakdown.
At what mileage does the fuel system typically fail?
Across the 11 complaints that reported odometer mileage, most fuel system failures cluster between 6,000 and 60,000 miles, with the median around 43,000. A quarter of owners report trouble before 6,000; a quarter make it past 60,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $1,200 for fuel system repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to fuel system?
No active recalls currently cover fuel system issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
