Suzuki SX4
Suzuki's own 2.0-litre diesel based on the Fiat 2.0 JTD. Known weaknesses include oil pump gasket issues, bursting charge air pipes, and the classic diesel problems with DPF and EGR.
Diesel crossover with long-haul character
The 2.0 DDiS in the SX4 offers good torque and low consumption. Too softly tuned for driving enthusiasts, but as a daily car it does its job well.
Engine Weaknesses 4
The oil pump gasket on the D20AA can become porous and draw in air, causing oil starvation and consequential bearing damage.
Symptoms: Low oil pressure warning light, unusual engine noises, engine failure in the worst case
The EGR heat exchanger on the D20AA develops persistent leaks and can allow coolant to enter the intake tract.
Symptoms: White smoke from the exhaust, coolant level drops, sweet smell from the engine bay
The charge air supply pipe on the D20AA tends to burst or develop leaks, causing a significant loss of power.
Symptoms: Sudden power loss, vehicle enters limp mode, hissing noise from the engine bay
The particulate filter on the D20AA blocks with frequent urban use. Regular motorway driving significantly slows the process.
Symptoms: DPF warning light, power loss, increased fuel consumption, frequent limp mode
Vehicle Weaknesses 4
The SX4 I-FL shows above-average front axle faults in TÃœV reports. Tie rod ends and ball joints wear prematurely.
On the SX4 I-FL, 100,000 km is the typical failure point for the alternator. The unit is almost routinely replaced at this mileage.
The SX4's air conditioning is a known weak point. Compressor failures and refrigerant leaks are the most common causes of lost cooling performance.
TÃœV reports show an increased fault rate for brake components on later-year SX4 models. Pads wear faster than on comparable vehicles.
