Audi Q3 Mk3 (FJ) Common Problems & Reliability
Revealed 16 June 2025 and on UK sale from late 2025 as a 2025/2026 model (The Car Expert and Parkers both list it '2025 onwards'), the third-generation Q3 is effectively a baby Q5: Q5-inspired looks, the curved digital cockpit Audi pushed into this class, a dashboard-mounted gear selector replacing the conventional lever and, for the first time in a Q3, a long-range e-hybrid plug-in with a 25.9kWh battery - Auto Express managed 54 miles on electric over mixed UK roads. The 1.5 TFSI mild-hybrid will do most of the volume. Early verdicts praise polish, space and refinement, but the criticism clusters on interior feel: Auto Express flags 'some flimsy materials in obvious places', an old-fashioned touchscreen housing and a cabin-noise shortfall; RAC calls out quality and spec stinginess; The Car Expert's aggregate notes road noise, the lack of physical infotainment buttons and a price that makes bigger Audis tempting. It is also now Audi's smallest combustion model alongside the A3 after the A1 and Q2 died in 2026, which supports residuals. Nothing has surfaced in the DVSA register yet for the new car - the used audit is still being written.

Most Common Audi Q3 Mk3 (FJ) Faults & Repair Costs
Cabin Noise Below Class Standard
Auto Express lists 'cabin noise could be improved' in its cons for the new Q3, and The Car Expert's aggregate specifically notes that a few outlets mark the car down for road noise. With the 1.5-litre three-cylinder mild-hybrid as the volume engine, the noise story at motorway speed is the tangible ownership compromise for a car that is otherwise markedly more refined than the F3 it replaced.
Roaring from the wheel arches above 60mph on coarse-chip motorway, Three-cylinder drone under hard acceleration intruding into the cabin, Wind noise around the A-pillars at speed
- Do a 70mph motorway leg on the test drive rather than only town driving
- Check which tyres are fitted - budget rubber exaggerates the noise
- Compare against a Q5, where reviewers found significantly more peace
Interior Materials and Spec Stinginess vs the Price
Two independent reviews land on the same point: Auto Express lists 'some flimsy materials in obvious places' and 'bits of trim feel a little downmarket', while RAC's cons flag 'some quality and spec stinginess'. In a car priced near Q5 money at the top of the range, the gap between the perceived interior quality and the badge premium is the main reason to spec carefully or buy the discounted outgoing generation - particularly with Audi moving several once-standard features into options for 2026.
Hollow door-card tops and loose trim that flexes under hand pressure, Cheaper plastics on the centre console surround, Minor rattles from trim panels over broken roads
- Press around the door cards, console and tailgate trim at the viewing, listening for flex and rattle
- Compare the trim specification against an outgoing F3 Q3 and a Q5 to calibrate value
- Check what is actually fitted - options lists differ sharply between Sport and S line cars
Dash-Mounted Gear Selector and Loss of Physical Buttons
The FJ moved gear selection to a stalk-like pod on the dash, which Auto Express found 'takes getting used to' alongside an 'old-fashioned touchscreen housing', while The Car Expert records reviewers marking the car down for a lack of physical infotainment buttons. Like the A5, Q5 and e-tron range, this generation is on the touch-first E3 interface whose physical-controller fix arrives on 2026MY Audis - so a used first-year Q3 is the version Audi itself is about to amend.
Driver reaches for a traditional gear lever that is no longer there, Menu-diving for media and climate while driving, Occasional infotainment lag or reboot
- Drive off, park, and reverse a full cycle to confirm the dash selector logic suits you
- Ask which MMI software build is fitted and whether the car can receive the latest release
- Compare against an F3 Q3 - the older car keeps a conventional shifter and more buttons
