All Known Issues

Relay Failure & Random Limp Mode

SeriousElectrics & Electronics

A bank of six micro-relays behind the front-right wheel well liner is a common failure point on the Stelvio. Faulty relays (Starter/Aux Pump) lead to no-start scenarios or random limp mode. Many owners proactively swap these for updated Mopar units.

Most affected: All Stelvio models

Estimated cost: £50–£150Affects: 2017–2024Often appears around: Any

Typical symptoms

  • •Random limp mode
  • •Vehicle fails to start/crank
  • •Battery drain

What to inspect before you buy

  • ✓Review service history for "6-relay swap"
  • ✓Check passenger wheel liner area for signs of access

Battery-Voltage & AGM Upgrade

ModerateElectrics & Electronics

The Stelvio is highly voltage-sensitive. The factory EFB battery is a known weak point. Upgrading to a Group Size H8 (LN5) AGM battery is a recommended fix for many "ghost" electrical warnings and start-stop issues.

Most affected: All Stelvio models

Estimated cost: £250–£500Affects: 2017–2024Often appears around: Often age-related (3+ years)

Typical symptoms

  • •Multiple warning lights at start-up
  • •Start-stop unavailable
  • •Power tailgate failing to close
  • •Infotainment resets

What to inspect before you buy

  • ✓Battery age/type (AGM upgrade is preferred)
  • ✓IBS sensor connection on the negative terminal
  • ✓Service history for BCM updates

Front Suspension & Inner Tyre Wear

ModerateSuspension & Chassis

The sharp steering comes at a cost of high stress on front bushings and anti-roll bar links. Heavy diesel models are particularly prone to inner edge tyre wear if the alignment isn’t set precisely.

Most affected: All models, especially those on 20-inch wheels

Estimated cost: £300–£800Affects: 2017–2024Often appears around: 30,000–60,000 miles

Typical symptoms

  • •Knocking over low-speed bumps
  • •Inner-edge tyre wear
  • •"Skipping" feel on full lock in cold weather

What to inspect before you buy

  • ✓Inner tread of front tyres
  • ✓Listen for suspension creaks
  • ✓Alignment records

AdBlue and NOx-Sensor Faults on 2.2 Diesel

ModerateExhaust & Emissions

UK diesel Stelvios can suffer from SCR and NOx-sensor warnings, particularly if the car has done lots of short journeys or seen repeated warning resets instead of proper repairs.

Most affected: 2.2 JTDm diesel

Estimated cost: £250–£1,200Affects: 2017–2024Often appears around: 30,000–90,000 miles

Typical symptoms

  • •Check engine or emissions warning
  • •AdBlue system message
  • •Limp mode on diesel cars

What to inspect before you buy

  • ✓Scan for SCR and NOx faults
  • ✓Check for sensor or injector replacement invoices
  • ✓Drive the car until fully warm

Buying Tips for the 2017 Alfa Romeo Stelvio

  • ✓A strong AGM battery matters on these cars because weak voltage creates a cascade of false warning lights and start-stop complaints.
  • ✓Inspect the inner edges of the tyres and listen for front-end noises because alignment and bush wear matter on heavy, wide-wheeled Stelvios.
  • ✓On 2.2 diesel cars, check for AdBlue, NOx or emissions-system faults even if the warning lights are currently off.
  • ✓Test all driver-assistance systems, cameras and the infotainment screen from a cold start because electrical niggles often appear before the engine is warm.
