Suzuki Jimny (Gen 4) Common Problems & Reliability
The fourth-generation Suzuki Jimny, launched in 2018, became an instant design icon with its retro, boxy styling that paid homage to the original model. Despite its fashionable appearance, it remained a serious, "no-nonsense" off-roader at heart, retaining the ladder-frame chassis, rigid axles, and low-range transfer case that defined its predecessors. In the UK, demand far outstripped supply at launch, leading to exceptional resale values that often exceeded the original list price, especially after the 4-seater model was discontinued in 2020 and replaced by the two-seater "LCV" commercial version. Mechanically, the Gen 4 Jimny is fundamentally robust, utilizing a simple and durable 1.5-litre naturally aspirated petrol engine that is easy to maintain. However, it still faces some of the traditional Jimny technical risks that used buyers should screen for. The most common complaint is the "death wobble"—a violent steering vibration at dual-carriageway speeds—which, while rarer than on the Gen 3, can still occur if the radius arm bushes or wheel balancing are neglected. Additionally, despite its modern design, the factory undersealing is relatively minimal, making early rust prevention a priority for UK owners who live in coastal or high-salt regions. When buying a used Gen 4 Jimny in the UK, the priority is verifying that the vehicle has not been abused during heavy off-roading or modified with poor-quality suspension kits. Prospective owners should carefully inspect the underside for damage to the chassis rails or differential cases and ensure that the 4WD system shifts cleanly into both high and low range. It is also important to verify whether you are buying a 4-seater passenger model or the later 2-seater LCV, as this has significant implications for both insurance and practical family use. A well-protected Jimny with a full Suzuki service history remains one of the most charismatic and value-stable used cars on the market.

Most Common Suzuki Jimny (Gen 4) Faults & Repair Costs
Chassis Corrosion (Lack of Protection)
The factory underseal is minimal, leading to early surface rust on the ladder frame.
Orange surface rust on the frame, Corrosion on bolt heads
- Look under the car at the main frame rails
Fuel Pump Impeller Swelling
A recall was issued for fuel pumps with a defective impeller material that can swell over time, particularly due to ethanol content in modern fuel. This can cause the pump to stop working and the engine to stall without warning.
Engine stalling without warning, Difficulty starting, Fuel pump warning light
- Check with a Suzuki dealer that the fuel pump recall has been completed
- Verify VIN against recall records on GOV.UK
Rear Wheel Bearing Failure
The rear wheel bearings can fail prematurely, especially on cars that have been used off-road or fitted with oversized tyres. The bearings are relatively inexpensive but labour-intensive to replace.
Humming or droning noise from the rear, Noise increases with speed, Play in the rear wheel when jacked up
- Jack up the rear wheels and check for play
- Listen for bearing noise during a test drive at 40-60mph
Door Wiring Harness Wear
A recall was issued for door harness wiring that can break from repeated opening and closing of the door. If the wiring breaks, the side impact airbag sensor may fail to operate in an accident.
Side airbag warning light, Door window or mirror intermittently not working, Interior light not triggering when door opens
- Check recall status with a Suzuki dealer
- Test all door-operated electrical functions
