2010 Toyota IQ 1.0L Petrol · CK10 VGP

The Toyota iq is currently roadworthy but the maintenance history shows a worsening trend regarding structural integrity and component degradation. The most recent test in April 2026 at 87,901 miles introduced a significant volume of advisories related to corrosion that were absent in previous years. While the vehicle passed, the emergence of rust across the rear sub-frame, mounting areas, and floor indicates that the vehicle's chassis is now reaching a stage of accelerated environmental decay despite the low mileage. The vehicle exhibits exceptionally low mileage for its sixteen-year age, averaging approximately 5,500 miles per year. The data shows a consistent and slow usage pattern, moving from 76,863 miles in March 2022 to 87,901 miles in April 2026. This low usage often explains why mechanical components like the engine remain viable while rubber components like brake hoses remain relatively fresh. However, the lack of regular high-speed driving likely contributed to the surface corrosion noted on the metal surfaces and brake-related hardware. A prospective buyer must conduct a thorough physical inspection of the rear sub-frame and floor pans to ensure the corrosion noted in the 2026 test has not progressed into structural thinning. The tester specifically flagged corrosion on the ferrules of all four brake hoses, which suggests the rubber may be perished and could require proactive replacement to prevent hydraulic failure. Additionally, the corroded nearside rear coil spring should be checked for hairline fractures or thinning that could lead to snapping. The recurring mention of deteriorated registration plates is a minor cosmetic concern but reflects a general lack of aesthetic maintenance.
