All Known Issues

Starlink Infotainment Screen Faults

ModerateElectrics & Electronics

The Starlink touchscreen fitted from around 2013 onwards can freeze, go blank or fail to reboot, with owners quoting roughly £1,500 for a dealer replacement unit. It is an annoyance rather than a safety fault, but electrical and dashboard-message faults are a common MOT area on the Forester.

Est. Repair Cost: £100–£1,500
Warning Signs:

Frozen or blank touchscreen, Delayed response to inputs, Reverse camera or sat-nav not loading

What to Inspect:
  • Test navigation, media and phone pairing
  • Watch for delayed reverse camera loading
  • Ask whether the head unit has been updated or replaced

e-Boxer 12-Volt Battery Drain

ModerateElectrics & Electronics

On 2020-on e-Boxer hybrids the small 12-volt starter battery can go flat or struggle to hold charge after the car sits for several days, especially on short local journeys. Battery condition and dashboard warning lamps are recorded MOT checks on this model.

Est. Repair Cost: £100–£250
Warning Signs:

Battery flat after a few days of sitting, Need for frequent jump-starts, Repeated premature battery replacement

What to Inspect:
  • Ask when the 12-volt battery was last replaced
  • Check the car starts easily after sitting for several days
  • Look for any charging or electrical warning messages

Suspension Knocking and Worn Bushes

ModerateSuspension & Chassis

Owners report creaks and knocks from the front end and rear subframe over speed bumps and potholes, usually traced to worn control arm bushes, strut top mounts or sway bar links. Suspension is the standout MOT failure category for the Forester, and Subaru recalled Foresters built April 2017 to May 2019 because rear stabiliser-bracket bolts could work loose.

Est. Repair Cost: £200–£600
Warning Signs:

Knocks or creaks over speed bumps and potholes, Clunking from the front or rear suspension, Uneven tyre wear

What to Inspect:
  • Drive over speed bumps at low speed listening for knocks
  • Check for play in suspension joints and links
  • Ask whether the rear stabiliser-bracket recall was carried out

Exhaust System Corrosion and Leaks

ModerateExhaust & Emissions

The SK's exhaust system can rust under UK winter salt, producing loud blowing or hissing noises and a potential MOT failure on exhaust noise, emissions or leaks. Noise, emissions and leaks is a recorded failure area on the Forester, more visible as the car builds mileage.

Est. Repair Cost: £250–£700
Warning Signs:

Loud exhaust roar or hissing, Rattling from underneath the car, Failed MOT on exhaust noise or emissions

What to Inspect:
  • Listen for an exhaust blow with the engine cold
  • Inspect the silencer and pipes for rust holes
  • Check MOT history for repeated exhaust advisories

Buying Tips for 2024 Subaru Forester Mk5 (SK)

  • Check Eyesight warnings clear immediately and ask about any windscreen replacement, as calibration is expensive if done badly.
  • e-Boxer cars should feel smooth in stop-start traffic; any hybrid or charging warning deserves investigation.
  • A quiet CVT and evidence of fluid changes matter more than a glossy dealer stamp book alone.
