Hyundai Accent
Compact three-pot diesel with common-rail. Sips fuel, but runs rough and runs out of breath quickly.
Cheap to run, that is all
The Accent is cheap, reliable, and utterly uninterested in entertaining anyone behind the wheel.
Engine Weaknesses 5
Older 1.5 CRDi (D3EA/D4FA predecessor) with timing belt drive. On these aged vehicles always check belt service history. Interference engine — severe engine damage if belt breaks.
Symptoms: Squealing, rattling; then sudden engine seizure with severe valve damage.
D3EA forum reports indicate injection problems due to low high-pressure pump output or defective injectors. Fuel rail pressure drops below 300 bar prevent correct engine starting.
Symptoms: Difficult cold start; rough running; power loss; possible stalling under load.
The small three-cylinder diesel D3EA shows boost pressure loss from turbocharger wear at higher mileages. Diagnosis: boost pressure below 200 kPa at full load is a sign of turbo damage.
Symptoms: Noticeable power loss; black smoke; no boost pressure build-up; turbo whistle absent.
The EGR valve on the D3EA three-cylinder diesel is prone to soot fouling and blockage. Hyundai forums report throttle response restrictions and limp mode as a result.
Symptoms: Engine enters limp mode; poor throttle response; check engine light; increased fuel consumption.
Reports from Hyundai Club EU: A defective camshaft or crankshaft sensor causes intermittent start failures on the D3EA. Diagnosis by OBD scanner is clear-cut.
Symptoms: Intermittent no-start; starter cranks but engine won't fire; no fault code visible under normal conditions.
Vehicle Weaknesses 13
The Accent LC brake lines are prone to corrosion, which is frequently flagged as a significant defect at MOT inspections. Rear axle lines in the underbody area are particularly affected.
Known issue on 2006–2009 models: faulty brake light switch prevents brake lights from illuminating when braking. Increased rear-end collision risk.
Brake lines corrode heavily from road salt and moisture. Brake line corrosion increases the risk of brake fluid leaks and dangerous brake failure.
The Accent LC shows early rust-through at wheel arches, sills, and door bottom edges. Vehicles from salt regions are regularly severely affected from 100,000 km.
On the Accent LC 1.3/1.5, misfires are common due to faulty ignition coils or corroded ignition cables. Vehicles from 2001 onwards are particularly affected.
The fuel pump on the Accent LC tends to fail at higher mileages. The engine then no longer starts or stalls while driving.
The rear fenders of the Accent LC tend to rust — especially the folds and seams to the bodywork corrode through. Multiple owners report severe fender rust after just 7–8 years.
Frequently reported problem: suspension springs corrode through, especially in regions with road salt. Corrosion possible on front control arms, fuel tank brackets, and strut towers.
The LC rear axle suspension shows wear on trailing arm bushings and control arm bolts at higher mileages. MOT defects frequently from the 8th year of operation.
The Accent LC does not have a particularly high-quality front axle — front shock absorbers wear from around 80,000 km, leading to increased tyre wear and poor road holding. Hydraulic tappets can damage the camshaft bearing when worn.
The central locking on the Accent LC often fails due to water ingress into the door motors. The interior door switch is also known to fail. Replacement parts are cheaply available on eBay.
Front suspension shows excessive play in bushings and ball joints. Engine mounts can be defective and cause vibrations. Typical for vehicles with high mileage.
45 Ah battery in the 1.6L model is too small for frequent short-trip use. The immobilizer occasionally prevents starting; temporarily disconnecting the battery helps.
