Owners report multiple distinct fuel-system and related powertrain failures across 15 vehicles. The most common issue is unintended loss of motive power while driving—the vehicle stalls, won't accelerate, or decelerated sharply with check-engine or "Engine Power Reduced" warnings lit. Several owners detected strong gasoline odors in the cabin or under the vehicle and spotted fuel leaks; one owner found gasoline pooling beneath the engine at 50,000 miles. A few reported fuel-injector failure (leaking or disconnected), fuel-line leaks requiring replacement, and fuel-pump failure. One owner couldn't refuel fully due to a faulty air control valve sensor. Engine-control module (ECM) failures appear tied to the stalling problem—multiple owners were diagnosed with ECM failure, and at least one underwent replacement. Vehicle behavior also included unexpected automatic emergency braking, radio controls failing, and steering issues. Many owners noted their vehicles were covered under NHTSA Campaign 19V642000 but not actually recalled, while others weren't included in the recall despite similar symptoms. One owner reported parts unavailable for recall repair.
Failure modes owners describe
Unintended stalling and loss of power while driving
Vehicle stalls or loses motive power while in motion, often accompanied by check-engine light or 'Engine Power Reduced' message. Speed varies from stopped at traffic light to highway speeds (70 mph). Power steering and braking may be lost. Vehicle may not restart without towing.
When: Various mileages: 2,141 to 186,000 miles; often early in ownership
Symptoms owners cite: Vehicle stalls without warning; Loss of motive power while driving; Check engine light illuminated; Engine Power Reduced message displayed; Loss of power steering and braking; Vehicle fails to respond to accelerator pedal; Vehicle decelerates unintentionally
Codes mentioned: Check engine
Repairs/costs cited: Engine control module (ECM) replacement reported in at least two cases; one replaced and repaired, one dealer provided estimate but not completed. Other owners' vehicles undiagnosed or repairs not completed.
Recalls/TSBs owners mention: NHTSA Campaign 19V642000 (Electrical System, Fuel System, Gasoline, Engine); however, multiple owners' VINs not included in recall despite similar symptoms. Manufacturer case number 9-5537893606 provided in one instance.
Fuel leaks and gasoline odor
Strong gasoline odor detected in cabin (via A/C vents) or under the hood. Fuel pooling or dripping found beneath vehicle. Fuel line or fuel injector leaks confirmed or suspected.
When: 50,000 to 130,000 miles
Symptoms owners cite: Strong gasoline odor in cabin or engine bay; Abnormal fuel odor through A/C vents; Gasoline pooling or dripping under vehicle; Fuel leak visible on ground
Repairs/costs cited: Fuel line replacement recommended in one case (not completed). Fuel injectors and unidentified parts reported failed in another. No repairs completed in any reported instance.
Recalls/TSBs owners mention: NHTSA Campaign 18V358000 (Fuel System, Gasoline) and 19V642000 referenced. One owner advised to file NHTSA complaint; no other manufacturer response documented.
Fuel injector failure
Fuel injectors leak or are disconnected, causing fuel odor and engine difficulty. One narrative mentions 'disconnected fuel injector' specifically.
When: 123,074 miles; timing unclear in one case
Symptoms owners cite: Strong fuel odor; Engine difficult to turn over; Fuel injectors leaking; Disconnected fuel injector reported
Repairs/costs cited: Independent mechanic diagnosed fuel-injector leaks in one case; no repairs completed.
Recalls/TSBs owners mention: NHTSA Campaign 18V358000 referenced. No manufacturer response documented in these specific cases.
Engine control module (ECM) failure
ECM failure results in vehicle stalling, power loss, and inability to restart. Appears to be root cause of several unintended power-loss incidents.
When: 75,000 miles (diagnosed); 2,141 miles (repair completed)
Symptoms owners cite: Vehicle loses power and stalls; Vehicle fails to accelerate; Vehicle fails to restart
Repairs/costs cited: ECM replacement completed in one case; one owner diagnosed but not repaired; one owner received dealer estimate but did not proceed.
Recalls/TSBs owners mention: NHTSA Campaign 19V642000. Manufacturer case number 9-5537893606 provided in one repair instance.
Fuel system electrical / fuel pump failure
Fuel pump failure combined with electrical ground issues prevents vehicle starting. Fuel tank replacement also mentioned.
When: 50,206 miles
Symptoms owners cite: Vehicle failed to start; No warning lights illuminated
Repairs/costs cited: Dealer diagnosed battery and fuel pump failure. Ground wire and fuel tank replacement required. Vehicle repaired but failure recurred.
Recalls/TSBs owners mention: Dealer informed owner of ECM recall; manufacturer contacted but provided no assistance for recurring issue.
Acceleration limiter / Engine Power Reduced mode
Vehicle fails to accelerate above 30 mph or shows reduced power, often with check-engine light. May be limp-home mode triggered by fuel or electrical fault.
When: 100,000 to 130,000 miles
Symptoms owners cite: Vehicle failed to accelerate above 30 MPH; Check engine light illuminated; Fuel odor present
Codes mentioned: Check engine
Repairs/costs cited: Fuel line replacement recommended in one case; fuel injector failure suspected in another. No repairs completed.
Recalls/TSBs owners mention: NHTSA Campaign 18V358000 referenced. One owner advised by manufacturer to file NHTSA complaint.
Fuel tank filler issue / Air control valve sensor failure
Vehicle unable to refuel to full capacity. Air control valve sensor in fuel tank filler system diagnosed as faulty.
When: Mileage unavailable
Symptoms owners cite: Unable to fill fuel tank to full capacity
Repairs/costs cited: Independent mechanic diagnosed faulty air control valve sensor requiring replacement; not repaired.
Parts unavailability for recall repair
Owner received recall notification (19V642000) and contacted dealer, but parts were unavailable. Manufacturer unable to confirm delivery date.
When: Mileage unavailable; no actual failure reported
Symptoms owners cite: No failure experienced; parts unavailable for preventive recall
Repairs/costs cited: Parts distribution disconnect reported by dealer and manufacturer.
Recalls/TSBs owners mention: NHTSA Campaign 19V642000; manufacturer unable to confirm parts availability timeline.
