Unconfirmed issues

Reported

Owner folklore from forums and the motoring press. Most of it never shows up in an MOT, which is why this section exists at all.

Paint peeling from the bonnet

Emerging

Owners have reported patches of paint lifting or peeling from the bonnet, most visibly on darker colours, with one documented case on a 2016 car surfacing in 2019. Infiniti's UK warranty ran to 3 years/60,000 miles and specifically covered paint imperfections, which suggests the factory was aware of a quality issue rather than it being pure bad luck. No formal recall exists, so a car out of warranty with peeling paint is the owner's bill, usually a respray of the affected panel.

Dual-clutch automatic hesitation and low-speed judder

Automatics only

Cars fitted with the seven-speed dual-clutch automatic (a design shared with Mercedes-Benz's 7G-DCT) can feel lazy pulling away and clunky shifting at parking speeds, and reviewers found the box's behaviour inconsistent between Eco and Sport modes when new. Dual-clutch units of this type are known elsewhere in the range for clutch-pack wear and judder developing with age, a repair that runs into four figures out of warranty. Manual-gearbox cars are not affected.

Cabin trim rattles and a dated, laggy infotainment system

Disputed

Reviewers found rattles and flimsy-feeling trim on test cars, with fit and finish behind BMW, Audi and Mercedes rivals away from the surfaces you touch most often, and the InTouch touchscreen was criticised for fuzzy graphics, slow menus and no Apple CarPlay or Android Auto on any UK car. Owners are split, some report no issues at all over years of ownership, others get persistent squeaks from the dash or door cards within a couple of years. It's a comfort and usability gripe rather than a safety one, and nothing here is covered once the warranty ends.

Firm ride and front-end knocks or creaks

Partly in the MOT data

The Q30 shares its underpinnings with the Mercedes A-Class, and reviewers marked the ride as firm and restless even in standard trim, worse on Sport models with their stiffer setup. Owners report creaks and knocks developing from the front end as mileage builds, with strut top mounts and anti-roll bar links the usual suspects on this platform. The measured MOT data backs this up, with suspension standing out as the fault category most likely to catch out Q30 buyers in this class, so a noisy front end on a test drive is worth taking seriously rather than writing off as normal wear.

Viewing one? Ask this

Built from the two sections above.

Check the bonnet, roof and door edges for paint that looks thin, bubbled or has clearly been resprayed. Peeling paint is a known early issue; a respray means it's already happened once.
Pull away gently from a dead stop, then try a slow stop-start crawl as if in traffic. A jerky clunk or hesitation on dual-clutch automatics is the start of the clutch-pack wear owners report; manuals won't show this.
Accelerate hard from low speed in Sport mode, then try the same in Eco. Feeling lazy in one mode and sharp in the other is normal for this car, but flaring revs or a harsh bang into gear is not.
Push down hard on each corner of the car and drive over speed bumps or rough tarmac. Creaks or knocks from the front end point to worn strut top mounts or anti-roll bar links, the area most likely to show up as a suspension advisory.
Read the MOT history for suspension advisories, especially repeated ones. This is the fault category that shows up most in the measured data for the Q30, so a clean history here matters more than most.
Flex the door cards and dash trim, and listen for rattles over a rough road. Persistent squeaks or creaks reflect known fit-and-finish inconsistency, and there's no warranty left to fix it for free.
Try the touchscreen, pairing a phone and scrolling through the menus. Slow, laggy response and no CarPlay or Android Auto is normal for the car's age; a screen that freezes or reboots on its own is not.
