What is the 2018-2024 Alfa Romeo Stelvio Low-Pressure Fuel Pump Failure Causing Stall (Recall 25V-667)?
2018+ Stelvios can experience sudden engine stall or no-start due to a defective low-pressure fuel pump inside the fuel delivery module — same defect as the Giulia, same supplier, same NHTSA timeline. The pump's internal commutator wears prematurely and loses contact, cutting fue… Repairs typically run $200-$2,000. Severity: high.
What is the 2018-2026 Alfa Romeo Stelvio Transfer Case Fluid Leak?
The Q4 AWD transfer case develops fluid leaks from the output shaft seal or housing gasket, resulting in low fluid levels and potential transfer case damage. The leak is often slow and goes unnoticed until noise develops. Repairs typically run $300-$1,800. Severity: high.
What is the 2019-2021 Alfa Romeo Stelvio ABS Hydraulic Control Unit Motor Rotor Shaft Separates Under Hard Braking (Recall 21V-309 / Y24)?
A supplier process fault left the rotor of the ABS hydraulic control unit's brushless pump motor with a missing or only partially completed weld to its shaft. Under hard braking - exactly the moment the unit is called on - the rotor can separate from the shaft, killing the pump. Severity: high.
What is the 2020-2021 Alfa Romeo Stelvio Fuel Line Sensor Housing Cracks and Leaks Fuel (Recall 21V-878)?
Separate from the low-pressure fuel pump campaign: on 2020-2021 Stelvios a fuel line sensor housing in the supply line can crack. A crack in a pressurised fuel line housing lets liquid fuel escape in the engine bay or under the car, which is a fire risk in the presence of an igni… Severity: high.
What is the 2018-2026 Alfa Romeo Stelvio Infotainment System Crash and Black Screen?
The Uconnect infotainment system crashes to a black screen during use, requiring a manual reboot. The issue affects navigation, climate controls, and the backup camera display during the outage. Repairs typically run $0-$1,200. Severity: medium.
What is the 2018-2026 Alfa Romeo Stelvio Turbo Oil Line Leak?
The turbocharger oil feed and return lines develop leaks at the banjo bolt fittings, causing oil drips onto the exhaust manifold and a burning oil smell. The copper crush washers at the fittings lose their seal over heat cycles. Repairs typically run $150-$600. Severity: medium.
What is the 2018-2026 Alfa Romeo Stelvio 2.0L Turbo Intake Valve Carbon Buildup Causing Cold-Start Misfire?
The 2.0L GME turbo four is direct injected, so no fuel washes over the back of the intake valves. Crankcase vapour routed through the PCV system bakes onto the valve heads and forms hard carbon deposits that disrupt airflow and seal quality. What makes the Stelvio case notable is… Repairs typically run $500-$1,200. Severity: medium.
What is the 2018-2025 Alfa Romeo Stelvio Parasitic Battery Drain From Modules Failing to Sleep, Repeat Dead Batteries?
One of the most-discussed problems in the Stelvio owner community and one of the most commonly misdiagnosed. A module that fails to enter sleep mode - most often the body control module, per forum consensus - keeps the CAN bus awake and holds current draw far above spec. Owners r… Repairs typically run $300-$1,200. Severity: medium.
What is the 2018-2024 Alfa Romeo Stelvio Water Pump Housing and Gasket Leak Causing Slow Coolant Loss?
A recurring cooling-system failure on the 2.0L cars, separate from the Quadrifoglio hose recall. The water pump leaks from the housing itself or from the housing-to-block gasket, producing a slow drip rather than a dramatic failure. Because the leak is small and the coolant on th… Repairs typically run $600-$1,200. Severity: medium.
What is the 2018-2025 Alfa Romeo Stelvio ZF 8HP Harsh 1-2 Shift and Cold-Weather Shift Clunk?
The Stelvio uses a ZF 8HP eight-speed automatic (8HP50 on the AWD 2.0L cars). Owners widely report a hard, clunky shift in the lower gears - most pronounced between first and second and worst before the transmission reaches operating temperature - along with hesitation on tip-in… Repairs typically run $150-$3,500. Severity: medium.
What is the 2018-2026 Alfa Romeo Stelvio Panoramic Sunroof Rattle and Wind Noise?
The panoramic sunroof develops rattling noises over rough roads and wind noise at highway speeds. The sunroof seal and guide rails are the primary sources of the noise. Repairs typically run $50-$600. Severity: low.
What is the 2018-2025 Alfa Romeo Stelvio Front Suspension Knocking and Clunking at Low Speed From End Links and Control Arm Bushings?
A widely reported complaint across the range, loudest at parking speeds and over small bumps. There is no single culprit, which is why owners often pay for the same repair twice. Sway bar end links are the most frequent source and are a genuine early wear item on this chassis, an… Repairs typically run $150-$1,800. Severity: low.
