Top issues to watch for

The most serious Hyundai Coupe problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Dangerous
Structural corrosion around suspension mounting points
GK, GK_FL1996–200920k–150k miles
MOT data shows this model fails at 28.3 times the fleet average for load-bearing structure problems within 30cm of suspension mounting points. This typically manifests as corrosion weakening the subframe mounting areas, particularly around the rear axle beam mounting points and front suspension turrets. Korean cars from this era are known for using thinner steel sections that corrode more rapidly than German or Japanese equivalents, especially in the UK's salt-heavy environment.
What happens if ignoredStructural failure around suspension mounting points can cause sudden loss of control, wheel detachment, or suspension collapse. The car is not safe to drive if structural integrity is compromised. Repair typically requires welding new metal sections or replacing the entire subframe assembly at costs that often exceed the vehicle's value.

Major
Suspension component damage and corrosion
GK, GK_FL1996–200920k–150k miles
MOT data shows this model fails at 99.6 times the fleet average for suspension component damage or corrosion, with 17.4 times the average for worn suspension pins, bushes, and joints. The rear axle beam design uses multiple mounting bushes that deteriorate rapidly, while front wishbones and anti-roll bar links corrode and wear prematurely. This is the most statistically significant failure mode for the Coupe in UK conditions.
What happens if ignoredWorn suspension components affect handling, braking stability, and tyre wear patterns. In severe cases, component separation can cause sudden handling changes or wheel alignment issues. Costs escalate quickly as multiple components typically need replacement simultaneously.

Major
Power steering system failure
GK, GK_FL1996–200920k–150k miles
MOT data shows this model fails at 70.4 times the fleet average for power steering fluid leaks or system malfunction. The hydraulic power steering pump and high-pressure lines are particularly prone to failure, with the pump developing internal seal leaks and the pressure lines corroding at connection points. Loss of power steering assistance makes the car difficult to manoeuvre at low speeds and in car parks.
What happens if ignoredComplete power steering failure makes low-speed manoeuvring extremely difficult and potentially dangerous in emergency situations. Pump replacement is typically required along with system flushing. Continued driving with failed power steering can damage the steering rack.

Parking brake efficiency problems
GK, GK_FL1996–20090k–150k miles
MOT data shows this model fails at 37.4 times the fleet average for parking brake efficiency below 50% and 30.1 times average for failing to meet minimum requirements. The cable-operated rear brake system suffers from cable stretch, adjuster seizure, and rear brake shoe/drum wear. Problems can manifest even on low-mileage examples, indicating design or material quality issues rather than normal wear.
What happens if ignoredIneffective parking brake creates safety risks on slopes and will result in MOT failure. Adjustment may temporarily restore effectiveness but worn components typically require replacement. Seized adjusters can make repair more expensive by requiring drum removal.
