Owners report engine stalls without warning at highway speeds and lower, with loss of power and fuel pressure. High-pressure fuel pump failure is the most commonly cited cause; dealers diagnosed failed injectors in at least one case and recommended fuel system testing for internal damage. Stalls occurred between 88,000 and 142,000 miles, often leaving owners unable to restart and requiring towing.
Diesel particulate filter failures show up as check engine lights and warnings that prevent further driving. One owner was told the vehicle would not start in 200 miles if a DEF quality issue wasn't fixed. The capless fuel door separated from the vehicle in one instance under 300 miles; separate cases report fuel spraying when refueling or the pump nozzle not shutting off.
Transmission hesitation, lunging, bucking, and improper gear selection are reported in tandem with engine stalls and check engine lights, particularly after refueling or on grades. A catalytic converter replacement was attempted in one case to address shuddering.
The biggest complaint is parts shortage for recall 22V406000 (Fuel System, Diesel). Multiple owners received recall notices but dealers couldn't schedule repairs for months because parts weren't available. Vehicles sat at dealerships waiting for components while owners remained without transportation, and some owners reported manufacturer delays exceeded reasonable timeframes.
Failure modes owners describe
Engine stall and loss of power — fuel delivery failure
Engine loses power, stalls without warning, or fails to restart. Owners report the high-pressure fuel pump failing, fuel system components needing replacement, or fuel pressure loss after attempted repair. Multiple owners cite injectors being inoperable or fuel system damage.
When: 98,000 to 142,000 miles; one case at 88,000 miles
Symptoms owners cite: Sudden stall while driving at highway speeds or lower; Loss of motive power, vehicle coasts to shoulder; Engine will not restart; Loud engine noise and hesitation on acceleration; Check engine light illuminated; Violent shaking before stall
Codes mentioned: DPF failure (diesel particulate filter), Diesel engine regeneration failure, Fuel pump diagnosis
Repairs/costs cited: High-pressure fuel pump replacement; fuel filter housing and high-pressure fuel line replacement; fuel system test and injector return test required to check for internal fuel damage; injector replacement (two of six injectors inoperable in one case)
Recalls/TSBs owners mention: NHTSA Campaign 22V406000 (Fuel System, Diesel) issued; recall parts unavailable at time of complaints; dealer confirms parts not available; owners delayed indefinitely
Diesel particulate filter and emissions system failure
DPF diagnostics indicate failure; emissions filter warning messages and DEF quality warnings appear. One owner was told no engine starts would be allowed in 200 miles if DEF quality issue not resolved.
When: 64,000 to 118,800 miles
Symptoms owners cite: Check engine light and emissions filter warning message; DEF quality detection warning: 'Incorrect Diesel Exhaust Fluid quality detected. No engine starts in 200 miles'; Service DEF system warning after water exposure
Codes mentioned: DPF failure code, DEF system fault
Repairs/costs cited: Eco diesel Extended Warranty had expired; DEF injector replacement needed in one case
Fuel system leak — post-recall
Fluid leaked under the vehicle after recall 22V406000 was completed at original dealer. Fuel filter housing diagnosed as the source and was replaced along with high-pressure fuel line.
When: 192,000 miles
Symptoms owners cite: Fluid leaking under vehicle after recall repair
Repairs/costs cited: Fuel filter housing replacement; high-pressure fuel line replacement
Recalls/TSBs owners mention: NHTSA Campaign 22V406000 completed; no case opened by manufacturer
Fuel filler neck defect — capless fuel door separation and overfill spray
Capless green fuel neck separates from vehicle during fueling, or fuel sprays back from filler neck when refueling. One case occurred at less than 300 miles; another reports fuel nozzle not shutting off. DEF service warning triggered after separation.
When: Under 300 miles; 4,000 miles
Symptoms owners cite: Fuel sprays from filler neck when refueling; Fuel nozzle does not shut off at pump; Capless fuel neck separates from vehicle; DEF service warning on dash following separation
Repairs/costs cited: Not repaired in any reported case
Transmission shift and stalling issues
Vehicle lunges, bucks, hesitates, or shudders under load. Transmission shifts erratically or fails to engage. Engine stalls after refueling or while driving. Check engine light and service transmission warnings appear.
When: Unknown mileage; one case mentions multiple occurrences over time
Symptoms owners cite: Vehicle lunges and bucks in stop-and-go traffic; Transmission shifts gears inappropriately while driving; Engine stalls after refueling or on highway; Shaking or shuddering while accelerating up a grade; Check engine light, service transmission light, and multiple service warnings illuminated
Repairs/costs cited: Catalytic converter replacement attempted in one case; dealer unable to replicate condition in another
Recall parts shortage — 22V406000 fuel system recall
Widespread delay in completing NHTSA Campaign 22V406000 (Fuel System, Diesel). Parts unavailable at time of recall notices; delays stretched months beyond reasonable timeframe. Many owners report contacting dealers and manufacturer repeatedly with no resolution or appointment date.
When: Recall notices issued; one owner advised appointment in December months after complaint
Symptoms owners cite: Unable to schedule recall repair; Parts not available at dealer; Manufacturer advises parts not available; Vehicle remains in dealer possession awaiting parts
Repairs/costs cited: Recall repair not completed; vehicles sat at dealers
Recalls/TSBs owners mention: NHTSA Campaign 22V406000 issued but parts unavailable; manufacturer confirmed parts shortages; one owner advised to call NHTSA Hotline
