2021 Fiat 500 HEY Google Mhev 1.0L Petrol · EU71 WYA

The latest DVSA MOT test for this 2021 Fiat 500 HEV/MHEV recorded a failure in December 2025 due to a tyre pressure monitoring system (TPMS) malfunction or complete inoperability, which is a critical road safety requirement under clause 5.2.3(h). This failure contrasts sharply with the previous two MOTs, which were both passed without defects, suggesting either a recent technical issue with the TPMS or a potential underlying electrical or sensor problem that has not yet resolved. While the advisory from December 2024 regarding tyre wear close to the legal limit on both front inner tyres indicates a recurring but non-failing concern, the absence of further failures in that area over the intervening year implies that the wear pattern may be stable, though vigilance is warranted. The overall maintenance trend appears to be stable for non-failing items, but the unresolved TPMS issue demands immediate attention to prevent potential safety risks. The vehicle’s recorded mileage of 46,193 miles at the time of this assessment represents a reasonable annual usage rate of approximately 9,239 miles per year, which is typical for a car of this age and class, particularly given its hybrid/electric powertrain efficiency. The consistent mileage accumulation without significant gaps or rapid increases suggests regular, moderate use rather than prolonged periods of inactivity, which could otherwise accelerate wear on consumables like brakes, tyres, and suspension components. However, the absence of mileage data for the period between the 2024 and 2025 MOTs means it is impossible to rule out any extended periods of standing, which could lead to issues such as brake disc corrosion, standing corrosion on suspension components, or fluid degradation in the electrical systems. The hybrid/electric drivetrain may also benefit from a check of the battery health and software updates, as prolonged disuse can sometimes affect battery performance or calibration. Given the unresolved tyre pressure monitoring system failure, the prospective buyer should prioritise addressing this issue first, as it is a mandatory roadworthiness requirement. The TPMS malfunction may stem from a faulty sensor, wiring issue, or software glitch, and a thorough inspection of the system’s electrical connections, sensor placement, and calibration should be undertaken. On a test drive, listen for irregularities in the vehicle’s warning lights or dashboard indicators, and verify that the TPMS displays accurate readings when the engine is running and the vehicle is stationary. If the issue persists, a professional diagnostic scan may reveal whether the problem lies with the sensor, the vehicle’s control module, or an external interference source. Beyond the TPMS, the advisories from the 2024 MOT regarding tyre wear close to the legal limit on the front inner tyres indicate that the buyer should conduct a detailed visual inspection of the remaining tread depth and tyre condition. Look for signs of uneven wear, which could suggest misalignment, suspension issues, or incorrect tyre pressures. The tyre sidewall should also be checked for signs of cracking, perishing, or dry rot, particularly given the vehicle’s age and the potential for prolonged exposure to environmental elements. Since the tyres were not legally defective at the time of the 2024 MOT, the wear progression appears to be gradual, but replacing them before they reach the legal minimum tread depth is advisable to maintain safety and traction. Additionally, with the vehicle’s hybrid/electric powertrain, the buyer should verify that the battery and associated electrical systems have been serviced or checked for any signs of degradation, such as unusual heat generation or reduced range. Lastly, given the vehicle’s age and the potential for standing, a check of the brake system for corrosion or binding calipers, and the fluid levels in the cooling, brake, and transmission systems, should be performed to ensure they are free of contaminants and at the correct operational levels.
