Build the inspection planTransmissionMedium
CVT behaviour under load.
- Typically appears
- 60,000+ miles
- What to inspect
- Feel for shudder when accelerating loaded.
ElectricalLow
Infotainment glitches and reboots.
- Typically appears
- Age-related
- What to inspect
- Test the touchscreen and CarPlay.
BrakesMedium
Steering wheel judder under braking due to prematurely warped front brake discs.
- Typically appears
- 15,000-30,000 miles
- What to inspect
- Perform a quick yard drive applying firm brake pressure from 30mph to feel for steering wheel vibration, and visually check front discs for heavy scoring.
Body/ElectricalMedium
Power boot lid fails to open fully, binds, or reverses direction with a warning beep.
- Typically appears
- 3-5 years
- What to inspect
- Cycle the power boot lid using both the key fob and dashboard button. Ensure it opens smoothly, holds its position, and latches securely without reversing.
SuspensionMedium
Clunking or knocking noise from the front end over bumps, caused by worn lower control arm bushes or strut mounts.
- Typically appears
- 40,000-60,000 miles
- What to inspect
- Do a tight figure-of-eight in the car park listening for knocks, and push down firmly on the front wings to check for strut noise.
ElectricalHigh
Parasitic battery drain causing non-starts, frequently linked to the DCM (telematics) module failing to enter sleep mode.
- Typically appears
- 20,000-50,000 miles
- What to inspect
- Check the battery date code for recent replacement. Connect a multimeter to check resting voltage; anything below 12.2V on the forecourt suggests a drain.

Build my inspection planFrequently asked questions
Is the Ascent reliable?
Generally, but confirm the fuel-pump recall and monitor oil.
Any Ascent recalls?
A fuel-pump recall and others exist; check NHTSA and confirm completion.
Is the Ascent good for families?
Yes — spacious three-row seating with standard AWD.
What should I check regarding the Ascent's towing capabilities?
The Ascent can tow up to 2,267 kg depending on the specification. When inspecting, check the rear subframe and tow bar mountings for excessive stress or corrosion. Ensure the factory transmission cooler is present, as heavy towing without it can prematurely degrade the CVT fluid and internal components.
Are there any specific servicing challenges with the 2.4-litre boxer engine?
Yes, spark plug replacement is notoriously labour-intensive on this flat-four engine due to the tight clearance against the chassis rails. It is scheduled every 60,000 miles. Dealers should check the service history carefully; if this major service was skipped, factor in around three to four hours of workshop labour.
Do all four tyres need replacing simultaneously on this all-wheel-drive system?
Subaru’s Symmetrical AWD system is highly sensitive to rolling radius variations. A tread depth difference of more than two to three millimetres between tyres can cause the centre differential to bind and overheat. Always check that all four tyres are the same brand, tread pattern, and have near-identical wear.
