2013 Toyota Yaris 1.0L Petrol · LT13 HSU

A front coil spring has failed twice within a short interval, which forms the central mechanical concern in this Yaris's recent DVSA history. Both fractures were recorded on the offside front unit, with the defect logged as a Major failure on 11 October 2025 and again on 16 December 2025. A vehicle passing immediately after the repair on 16 December 2025 means the spring was replaced between those two visits, but the recurrence of the identical failure mode on the same corner is worth registering. Elsewhere, the 2023 test produced a cluster of exhaust and emissions-related Major failures, indicating a leak at the rear exhaust section that prevented the emissions test from being completed. Aside from these two episodes, the remaining tests across 2022, 2023 (post-repair), and 2024 returned clean passes with no recorded advisories, though the 2022 entry did flag five separate items that warrant attention. With thirteen years on the road and 65,795 recorded miles, the Yaris has accumulated roughly 5,061 miles annually, which is on the lower side for its age and likely reflects a mixture of light commuting and periods of reduced use. There are no multi-year gaps in the MOT sequence, and the test dates track consistently from 2022 through 2025, suggesting the vehicle has been kept on the road throughout rather than laid up for extended storage. Low annual mileage tends to reduce wear on drivetrain and major consumables, but it can simultaneously accelerate corrosion on suspension links, brake components, and exhaust fittings due to short journeys and infrequent long runs that would otherwise help dry the system out. The combination of moderate age and limited mileage therefore aligns with the type of advisories observed in 2022, particularly corrosion on the front suspension arms and surface deterioration on the front brake discs. Given the recurring offside front coil spring failure, a physical inspection of the replacement spring and its mounting seat is essential, along with a check of the nearside front coil for any early signs of fracture such as localised rust pitting or uneven ride height. A fractured or weakened coil spring typically produces audible clonks or thuds from the front suspension over bumps, uneven nose dive under braking, and a perceptible lean to one side when stationary. The 2022 advisories on front suspension arm corrosion, while not serious at the time, should be re-examined now that the vehicle is another three years older; look for flaking or section loss around the arm body and bushes, and listen for knocks or clonks over uneven surfaces that would indicate worn bushes rather than simply aged paint. The nearside front lower arm and offside front arm were both flagged, so both sides merit close visual inspection for progression, particularly at the bushed pivot points where corrosion can compromise structural integrity. The exhaust system warrants particular scrutiny in light of the 2023 rear section failure. Inspect the full length of the exhaust for signs of patching, surface rust, or active leakage, paying close attention to the joint between the rear silencer and the connecting pipe where the leak was previously recorded. On the road, an exhaust leak often presents as a ticking or hissing sound that changes with engine speed, particularly noticeable from the rear underside on overrun. The 2022 advisory on nearside front tyre wear close to the legal limit should be checked for current tread depth and any uneven shoulder wear indicative of an alignment issue or worn suspension geometry. Finally, test the brakes firmly at low speed to feel for any judder or vibration through the pedal that might indicate the previously noted disc wear has progressed to a point requiring replacement, and verify that the offside front brake disc matches the nearside in condition, as paired replacement is advisable if either is found to be beyond service limits.
