Toyota Auris Mk2 Common Problems & Reliability
The second-generation Toyota Auris (2012–2018) was a pivotal model that successfully established Toyota as a leader in the UK's hybrid hatchback market. By moving away from the "mini-MPV" styling of its predecessor, the Mk2 Auris introduced a lower, sharper design that positioned it more effectively against the Volkswagen Golf and Ford Focus. In the UK, it has earned a reputation as one of the most sensible and durable used cars on the market, prized for its exceptionally low running costs and the effortless driving experience provided by its advanced hybrid powertrain. Reliability is the Auris's standout attribute, with the 1.8-litre Self-Charging Hybrid system being widely regarded as "bulletproof." These cars are frequently used in the UK taxi trade, often reaching 200,000+ miles with only routine maintenance. While fundamentally robust, there are a few minor issues to watch for; rear brake discs are prone to premature corrosion and sticking calipers, especially on cars used infrequently, and the 12V auxiliary battery can drain if the car is left sitting for long periods. Unlike many rivals, the Auris avoided major mechanical scandals, with most owner complaints revolving around the somewhat dated "Touch & Go" infotainment system. When buying a used Mk2 Auris in the UK, the Hybrid model is the recommended choice for both long-term reliability and resale value. Prospective owners should verify that the car has received a "Hybrid Health Check" annually at a Toyota dealer, as this maintains the manufacturer's battery warranty for up to 15 years. It is also important to check the service history for regular oil changes and to ensure that the interior plastics—which are durable but can be prone to scratching—are in good condition. For those seeking maximum practicality, the "Touring Sports" estate model offers a massive boot and remains one of the few hybrid estates in this price segment.
