Owners report a cluster of drivability and fuel odor issues, many tied to NHTSA Campaigns 25V467000 and 22V859000 (fuel-system gasoline). The most common symptoms are hesitation and stalling during acceleration or at stops, rough idling, and difficulty starting—especially after refueling. Several owners report the check engine light coming on; a handful describe rough cranking or choking sounds at startup. Some note abnormal fuel odor in the cabin; a few report smoke from the engine bay or A/C vents. One owner reports fuel leaking from fuel injectors on top of the engine.
Dealers have diagnosed fuel-injector failures most frequently, with some also finding purge-valve problems or transmission shudder. One owner reports a high-pressure fuel pump failure. Several complaints mention the recall remedy parts are unavailable, and dealers have informed owners that wait times exceed reasonable limits. A few owners report the dealer updated engine-control software as an interim measure but no permanent fix was completed.
Cost data and repair completion details are sparse in these narratives. The manufacturer has not provided significant assistance to most complainants, and many were told diagnostic work would be out-of-pocket. The core issue: owners have fuel-system failures and recall notifications but cannot get repair parts.
Failure modes owners describe
Fuel-injector failure
Fuel injectors fail, causing poor fuel delivery, rough running, hard starts, and hesitation. In one case, injectors leaked fuel on top of the engine. Dealers have replaced injectors in at least two cases, and multiple owners report dealers diagnose injector failure but cannot complete repairs due to parts unavailability.
When: Reported from 15,000 to 80,000 miles; most common in the 40,000–80,000-mile range.
Symptoms owners cite: difficult or no start; hesitation during acceleration; rough idle; rough running; fuel odor in cabin; fuel leak on engine; stalling during driving; poor acceleration response
Codes mentioned: P0300, P0171, P0174
Repairs/costs cited: Fuel injectors replaced in at least two cases; parts unavailable for recall repair in many others. One owner paid for independent fuel-injector replacement.
Recalls/TSBs owners mention: NHTSA Campaign 25V467000 issued; parts unavailable. Dealer informed owners the recall remedy was not available. Manufacturer advised some owners to call NHTSA Hotline. Some owners told service would be out-of-pocket.
High-pressure fuel pump failure
High-pressure fuel pump fails, preventing adequate fuel pressure to the engine. One owner reports independent mechanic diagnosed both failed fuel injectors and high-pressure fuel pump.
When: Approximately 41,000 miles
Symptoms owners cite: failure to start immediately; requires multiple start attempts; failure to accelerate as intended; rough driving
Repairs/costs cited: Fuel injectors were replaced by independent mechanic; high-pressure fuel pump repair status unknown (pending dealer diagnostic).
Recalls/TSBs owners mention: Not notified of the failure.
Purge valve failure
Purge valve fails, causing check engine light and possibly hesitation. One dealer diagnosis confirms purge-valve failure; owner replaced the purge valve out-of-pocket. Fuel injectors were confirmed in good condition in that case.
When: 69,527 miles
Symptoms owners cite: check engine warning light illuminated; vehicle hesitation during acceleration
Repairs/costs cited: Purge valve replaced by dealer. Fuel injectors verified in good condition.
Recalls/TSBs owners mention: NHTSA Campaign 25V467000 issued; parts unavailable for recall repair. Manufacturer notified but no assistance offered.
Engine stalling and rough idle under load
Engine stalls without warning or with hesitation during acceleration, at stops, or during turns. Vehicle may shake abnormally. Some cases involve choking sound at startup. Multiple owners report the vehicle stalls while driving and requires restart; one stalled while approaching a red light.
When: Reported from 4,000 to 90,000 miles.
Symptoms owners cite: unintended engine stall; stalling at red lights; stalling during driving; hesitation during acceleration; vehicle shaking or vibration; choking sound at startup; engine stumbling
Repairs/costs cited: Not repaired in most cases. Manufacturer advised one owner parts would be available within two years. No cost data provided.
Recalls/TSBs owners mention: NHTSA Campaigns 22V859000 and 25V467000 issued for fuel-system gasoline. Parts unavailable for many owners. Manufacturer told one owner parts would be available within two years.
Abnormal fuel odor (strong gasoline smell)
Strong gasoline odor enters the vehicle cabin or is present around the engine. Not always accompanied by a drivability symptom, but owners associate it with fuel-system malfunction. At least one narrative indicates odor after refueling.
When: Reported from 20,000 to 90,000 miles.
Symptoms owners cite: strong fuel odor in cabin; fuel-burning smell entering interior; gasoline smell inside vehicle
Repairs/costs cited: Not repaired in any narrative.
Recalls/TSBs owners mention: NHTSA Campaigns 22V859000 and 25V467000 issued. No specific remedy offered beyond recall notification. Parts unavailable.
Smoke from engine or A/C system
Smoke or fumes enter the cabin through air vents or appear under the hood. One owner reports smoke from the engine compartment and A/C unit during stall event. Another reports smoke entering the cabin through vents and under the hood at startup.
When: 75,000 and 90,000 miles
Symptoms owners cite: smoke from engine compartment; smoke from A/C unit; smoke entering cabin through air vents; fumes under hood
Repairs/costs cited: One fuel-injector replacement needed (parts unavailable). No other repairs completed.
Recalls/TSBs owners mention: NHTSA Campaign 25V467000 issued. Parts for recall repair not available.
Delayed or failed cold-start condition
Vehicle hesitates to start, requires several attempts, or fails to start immediately after refueling. Cold starts produce abnormal sounds (rattling, knocking, choking). Engine requires continuous accelerator pedal depression to overcome hesitation.
When: Reported from 15,000 to 82,000 miles.
Symptoms owners cite: vehicle fails to start immediately; requires multiple start attempts; hesitation during cold start; choking sound at startup; rattling sound during cold start from underneath vehicle; knocking sound at startup
Repairs/costs cited: No repairs completed in reported cases.
Recalls/TSBs owners mention: NHTSA Campaigns 22V859000 and 25V467000 issued. Parts unavailable.
Acceleration hesitation and poor throttle response
Vehicle hesitates, jerks, or sputters when accelerator is depressed, whether from a stop or while driving. In severe cases, vehicle fails to accelerate above 10 MPH. Symptoms occur both during initial acceleration and mid-range driving.
When: Reported from 18,474 to 80,000 miles.
Symptoms owners cite: hesitation when depressing accelerator; jerking during acceleration; sputtering during acceleration; failure to accelerate above 10 MPH; delayed throttle response; vehicle jerks while in park
Repairs/costs cited: One unknown repair completed at dealer did not resolve the failure. Most vehicles not repaired.
Recalls/TSBs owners mention: NHTSA Campaigns 22V859000 and 25V467000 issued. Manufacturer informed in a few cases; no assistance provided.
Engine control software issue
Engine control software required update or reset. One dealer performed an interim software update as a temporary remedy, but the failure persisted and permanent repair was not completed.
When: Approximately 47,000 miles and 63,000 miles
Symptoms owners cite: hesitation and stalling while driving; burning odor during operation
Repairs/costs cited: Engine-control software updated as interim repair by dealer; did not resolve fuel odor complaint. Unknown repairs pending at dealer in another case.
Recalls/TSBs owners mention: Recalled under NHTSA Campaign 22V859000. Manufacturer advised parts would be available within two years in one case.
