2011 Toyota IQ 1.0L Petrol · GL60 DMZ

A pattern of recurring brake-related advisories defines the mechanical story of this Toyota IQ, with every test recorded in the supplied DVSA history showing either clean or advisory-only entries rather than any structural or safety failure. The most recent examination on 18 June 2026 was a pass, but it carried advisories across both axles: front and rear brake pads noted as wearing thin, the front discs marked as worn though not excessively on both sides, and the rear discs flagged as petted or scored without being seriously weakened. Earlier results are notably sparse on advisories, with clean passes in 2020, 2021, 2023 and 2025, so the sudden cluster of brake wear flags in the latest test does suggest that consumables are approaching a replacement threshold. A minor failure was recorded on 15 June 2022 for an insufficient washer reservoir, and a retest the same day produced a clean pass. The 2024 test introduced two minor items relating to deteriorated dust covers on the offside front anti-roll bar linkage ball joint and lower suspension arm ball joint, alongside age-related perishing on both front tyres. With approximately 84,025 miles recorded across fifteen years, the iQ has covered roughly 5,600 miles annually, which is a notably low accumulation rate for a vehicle of this age. The testing record shows consistent annual attendance from 2020 onwards with no extended gaps, indicating the car has remained in regular use rather than laid up for prolonged periods. Low annual mileage of this nature typically reduces wear on high-cycle components such as the clutch, internal engine bearings and gearbox synchros, but it does mean that certain deterioration mechanisms still proceed regardless of use. Brake discs in particular suffer surface corrosion and pitting from infrequent and low-speed driving, which is consistent with the rear disc pitting flagged at the most recent test. Rubber components such as ball joint dust covers, suspension bushes, and tyres also degrade with age rather than mileage, which aligns with the perishing noted on the 2024 inspection. For a prospective buyer, the immediate priority is a close assessment of the braking system given the four advisories issued at the latest test. On a test drive, listen for any binding or scraping from the calipers as the car rolls to a stop, check for a soft or spongy pedal feel that might indicate worn seals, and look for pulling to one side under braking that could suggest a seized slider or uneven disc wear. The front discs should be inspected for a pronounced lip on the outer edge and the rears for the depth of pitting corrosion, as pitted surfaces may soon require replacement rather than skimming. The minor advisories from 2024 regarding the offside front anti-roll bar ball joint and lower suspension arm ball joint dust covers should be re-examined, as perished covers permit water and grit ingress that rapidly destroys the joint itself. With the vehicle jacked, check for any play or clonking from these joints when the wheel is rocked, and listen for knocking over uneven road surfaces which would indicate worn bushes. Tyre condition warrants careful inspection given the perishing noted on both front outer tyres in 2024, particularly as the car may still be running on the same set two years later. Look closely at the sidewalls for crack patterns, check the tread depth across the full width rather than just the central grooves, and confirm the manufacturing date stamps are within an acceptable age bracket. The suspension should be evaluated by pressing down firmly on each corner and releasing to verify the car rebounds smoothly without bouncing, and by driving at low speed over speed bumps to detect any knocking or clonking from worn strut top mounts or drop links. Finally, although the 2022 washer fluid failure was minor and clearly remedied the same day, it is worth confirming the washer system operates correctly on both front and rear jets, as electrical faults in the pump or switch can recur without being recorded as an MOT failure until the reservoir is actually inspected.
