2018 Mazda CX-5 2.2L Diesel · CU18 YWT

The 2018 MAZDA CX-5 has demonstrated a generally stable roadworthiness profile across its eight-year history, with five consecutive passes between 2022 and 2025 establishing a baseline of compliance. A single advisory appeared in July 2025 regarding the towball and hitch not being fitted at the time of testing, followed by a clean pass in August 2026 with no reported defects. The tyre concern from June 2021, where the nearside rear tyre was found worn close to legal limits and displayed edge wear, represents the most significant individual issue in the recorded history. Overall, the vehicle's MOT record shows intermittent minor advisories rather than systemic problems, indicating the chassis and drivetrain have remained structurally intact while specific components required attention at isolated points. With 67,035 recorded miles accumulated over approximately eight years, the average annual mileage stands at roughly 8,380 miles, which aligns with typical usage patterns for a model of this age. The test coverage reveals two distinct gaps in the record: a six-month interval between the 2021 tyre advisory and the subsequent 2022 pass, and a four-month gap following the 2022 clean test before the next assessment in mid-2023. While the yearly accumulation appears consistent, the presence of non-passing conditions in 2021 and 2025 indicates that certain systems did not remain within specification throughout the vehicle's operational life. The spacing between assessments does not suggest any acceleration in wear but rather reflects standard MOT scheduling intervals with occasional maintenance interventions requiring re-testing. The nearside rear tyre condition identified in May 2021 warrants particular attention during any test drive, as edge wear on a worn tyre can affect handling balance and may indicate underlying alignment or suspension geometry concerns. When inspecting this component, look for tread depth measurements approaching the legal minimum threshold and any visible cupping or irregular wear patterns along the outer edge. Additionally, verify that the tyre pressure matches the manufacturer's recommended specifications and that the wheel assembly remains securely mounted without play at the lug nuts or caliper mounting points. Any abnormal noise or vibration transmitted through the body when traversing rough surfaces should also be noted, as these can signal deeper suspension bush wear or loose subframe connections. The towball and hitch advisory from July 2025 highlights a critical connection point that must be confirmed in good working order prior to purchase, even though the subsequent August 2026 MOT passed without flags. Ensure the tow bar is fully installed and securely fastened to the front axle, with all bolts torqued to specification and the hitch receiver properly aligned. Inspect the tow hitch itself for signs of corrosion, cracks, or excessive play that could develop over time despite the initial advisory being resolved by the time of the later test. Given the flat floor design common to the CX-5 platform, verify that the subframe and crossmember are free of surface rust or pitting that might compromise structural integrity, particularly around wheel arches and door sills where moisture infiltration is most likely.
