Common Hyundai Problems

A streamlined saloon sharing the E-GMP platform with the Ioniq 5. Extremely efficient but shares the same ICCU hardware vulnerabilities and 12V charging logic bugs.

A retro-futrinsic EV on the E-GMP platform. Highly acclaimed, but early cars have been defined by ICCU (Integrated Charging Control Unit) hardware failures and 12V battery management bugs common to the platform.

The latest Tucson is a bold, high-tech SUV that has been a huge sales success in the UK. Early technical patterns suggest focusing on the ICCU and GPF, along with DCT smoothness.

A high-tech city car that has proven very reliable early in its life. The main issues are minor electrical failures and a specific EGR concern on very recent models.

The latest i20 is a sharp-looking hatchback with advanced mild-hybrid tech. While generally reliable, the 7-speed DCT and 48V battery systems require inspection.

One of the best-range EVs for the price. Early 64kWh models had a major battery recall (LG Chem cells) which should be verified as completed.

The PD i30 is a refined and safe family car. It introduces mild-hybrid tech and more advanced safety systems, but retains some of the DCT and diesel soot issues seen in other models.

A popular compact SUV. Petrol models offer good reliability, while the Hybrid uses the same powertrain as the Ioniq and shares its DCT and GPF characteristics.

The Ioniq is a highly rated hybrid that rivals the Prius. While generally very reliable, it has specific issues with 12V battery drain and the Dual-Clutch Transmission (DCT) which requires careful monitoring.

The GB i20 feels far more mature than the PB and is one of the better-value used superminis in the UK. It is usually dependable, but buyers still need to screen for steering-column noises, low-use diesel issues and front-end wear on hard-driven cars.

A very popular family SUV in the UK. Generally reliable by class standards, but the dry-clutch DCT, rear suspension wear and water-sensitive camera and infotainment hardware are the areas buyers should focus on.

The second-generation Hyundai i10 (2014–2019) represents a major leap forward from its predecessor, offering a level of interior quality, refinement, and equipment that made it a dominant force in the UK city-car market. With its grown-up styling, spacious cabin, and composed driving manners, it became the benchmark for a sensible, practical urban runabout. In the UK, it was highly regarded for its impressive reliability, often topping owner satisfaction surveys and proving to be an exceptionally dependable choice for both new drivers and small families. Despite its strong reputation, the i10 is not entirely immune to the demands of UK road conditions. The most frequently reported issues relate to premature clutch wear, particularly in examples used heavily for city stop-start driving, which can manifest as juddering when pulling away or difficulty engaging lower gears from cold. Mechanically, the suspension is robust, though high-mileage examples may develop knocking noises over bumps due to worn drop links or suspension bushes. Owners should also be aware that the rear brake pads can occasionally stick to the discs if the car is left standing, leading to uneven braking performance. When buying a used i10 Gen 2 in the UK, prospective owners should look for an example with a full service history to ensure maintenance was kept up to standard. During a test drive, it is crucial to pay close attention to the clutch biting point and smoothness of gear shifts, as these are the primary indicators of a car’s past life. Prospective owners should also check for any signs of surface rust underneath the vehicle and verify that all electronic features, such as the immobiliser and tyre pressure sensors, are operating correctly. A well-maintained i10 Gen 2 remains an excellent, budget-friendly choice that continues to offer superior reliability compared to many of its contemporary rivals.

The second-generation Hyundai i30 (GD), produced between 2012 and 2017, was a transformative model for Hyundai in the UK, signaling a move towards more sophisticated, European-focused design and engineering. It famously topped many UK owner reliability surveys during its production run, often outperforming premium rivals with its combination of robust build quality, comfortable ride, and excellent interior packaging. In the UK, it quickly gained a reputation as a sensible, no-nonsense family hatchback that offered a compelling blend of practicality and value. While mechanically dependable, the i30 GD is now at an age where high-mileage wear-and-tear items require closer inspection. The 1.6-litre CRDi diesel engine is generally durable, but if used primarily for short urban trips, it can be prone to Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) valve clogging, which can trigger recurring warning lights. Owners of manual models should be mindful of potential clutch wear, while those interested in the later 7-speed dual-clutch transmission (DCT) should test it thoroughly for any jerky behaviour in slow-moving traffic. Suspension-wise, the i30 is generally solid, although worn front drop-links are a frequent MOT advisory as vehicles reach higher mileages. When searching for a used i30 GD, the most critical factor is finding an example with a consistent service history, ideally showing oil changes carried out at sensible intervals. Prospective owners should listen carefully for any timing-chain rattle on cold starts, as high-mileage diesel units may eventually require attention. It is also recommended to inspect the interior for any cosmetic "peeling" on the steering wheel trim, and to ensure the infotainment and reversing camera systems are functioning without intermittent glitches. A well-kept i30 GD remains a highly competitive used purchase, often offering a more straightforward ownership experience than many of its more complex European rivals.

A very usable family SUV and still a common sight in the UK. Most big bills come from diesel emissions faults, steering-column noises and neglected AWD driveline wear rather than terminal engine failures.

The first UK i20 is a straightforward, honest supermini that usually ages better than period Corsas or Fiestas. Most trouble is wear-and-tear rather than design disaster, but neglected cars still bring steering noise, tired front suspension and diesel emissions headaches.

A dependable little city car that usually survives abuse better than many rivals. Most ownership costs come from clutches, brakes and tired front-end suspension rather than major engine faults.

The first i30 is a sensible, unfussy family hatch that often survives UK life well if basics were kept up. The problems are mostly age-related: springs, bushes, diesel soot loading and the occasional steering-column knock on later cars.

Tough and straightforward, and often a better bet than contemporary small European hatchbacks. The weak points are mostly consumables, corrosion underneath and tired steering or wheel bearings on neglected UK cars.

The LC moved the Accent on with cleaner styling, better crash protection and a more grown-up cabin, but it stayed a budget small car underneath. In today’s market the sensible buys are the ones with solid shells, tidy rear suspension and evidence that ignition or sensor faults have already been sorted.

The X3 is a very simple 1990s supermini that can still make sense as ultra-cheap transport, but by now condition matters far more than spec. Rust, neglected cooling systems and tired rear running gear are the real reasons good-looking cars turn into money pits.
