Toyota Aygo Mk2 Problems by Year

The second-generation Toyota Aygo (2014–2021) brought a sharp, "X-design" aesthetic to the city car segment, successfully distinguishing itself from its Citroën C1 and Peugeot 108 platform-mates. While it shared the same robust chassis and 1.0-litre engine, the Aygo was often seen as the premium choice of the trio due to Toyota’s slightly more generous equipment levels and its reputation for superior build quality and customer service. In the UK, it has been a consistent best-seller for young drivers and city dwellers, prized for its exceptionally low running costs and "Group 1" insurance rating. Reliability is a major strength, with the 1.0-litre three-cylinder engine being a simple, chain-driven unit that is widely considered "bulletproof" if serviced regularly. However, the Mk2 Aygo does have documented weak points, most notably a relatively small clutch that can wear out prematurely in purely urban driving environments. Water ingress is another common UK issue, with door and tailgate seals known to perish, potentially leading to damp footwells or water pooling in the spare wheel well. Early production models (2014–2016) have also been noted for early signs of brake pipe corrosion, a frequent MOT advisory for the model. When buying a used Mk2 Aygo in the UK, the 2018-onwards facelift model is the most desirable as it introduced improved cabin refinement and standard smartphone integration via Apple CarPlay and Android Auto. Prospective owners should carefully test the clutch for a high biting point or slipping and check for any signs of dampness under the carpets or in the boot. While the "x-shift" automated manual transmission offers two-pedal convenience, it is generally less refined and reliable than the traditional 5-speed manual, which remains the recommended choice for a trouble-free ownership experience.
