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.

Significantly more refined than the first generation, the i10 Gen 2 remains a UK favorite. It is mechanically robust but shares the same clutch sensitivities and minor electrical quirks as other small Hyundais.

The GD i30 is the more rounded and more desirable used buy, with better refinement and cabin quality than the FD. It still shares Hyundai/Kia steering issues and diesel after-treatment risks, while tired suspension and camera or media faults show up on higher-mileage UK cars.

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.
