Suzuki Jimny · Convertible
Robust 1.3-litre four-cylinder with timing chain and solid-bucket valve clearance adjustment (shim-over-bucket). Extremely long-lasting with regular maintenance — service lives of up to 250,000 km without a major overhaul are documented. Weak points are valve clearance adjustment, sporadic sensor failures at high mileage, and elevated oil consumption during sustained motorway use.
Automatic Jimny for the long off-road tour
With the automatic the old Jimny becomes a little more comfortable — its off-road abilities remain fully intact. Ladder frame, low-range transfer case, solid axles: all present. For tours where you crawl along at walking pace for hours, the automatic is a genuine advantage.
Engine Weaknesses 4
The M13A crankshaft sensor typically fails when hot: the engine stalls but restarts after cooling down. A fault code is often not stored because the ECU interprets the event as a normal stall.
Symptoms: Engine stalls suddenly when hot, restarts after a cooling pause. Rev counter flickers briefly before shutdown. No or sporadic fault code in OBD.
The M13A uses solid lifters with shims. Without regular inspection every 30,000 km the clearance tightens, causing metallic ticking on cold start. Shim special tools are essential for the adjustment.
Symptoms: Metallic ticking or tapping immediately after cold start, subsiding after warm-up or becoming louder at higher revs.
From around 160,000 km the M13A's oil consumption rises noticeably. The causes are piston ring wear and hardened valve stem seals. Sustained high-rev motorway driving accelerates wear significantly.
Symptoms: Oil level drops noticeably between changes. Light blue smoke from exhaust under high load. Oil spots under the vehicle possible.
The M13A ignition coils can fail intermittently when hot, causing cylinder misfires. Symptomatically similar to a crankshaft sensor fault, but can be differentiated by swapping the coils.
Symptoms: Hesitation and misfires especially when hot, briefly running on three cylinders, MIL on with per-cylinder fault code (P030x).
Vehicle Weaknesses 6
The Jimny JB43 has inadequate factory rust protection. Particularly vulnerable are the wheel arches behind the plastic trim, sills, spare wheel well, rear floor, and body sills. Perforating rust often appears after just 5–8 years.
The kingpin bearings seize prematurely due to water, dirt, and salt ingress. The lower bearing is particularly affected. Without maintenance, steering play develops, leading to dangerous steering shimmy.
The Jimny's short-wheelbase design makes it susceptible to severe steering shimmy at 70–110 km/h. The cause is accumulated play in the kingpins, track rod ends, Panhard rod, and tyre imbalance. Multiple components need to be inspected and replaced.
The Jimny's braking system is undersized from the factory and wears quickly through off-road use and corrosion. Brake hoses, wheel cylinders, and brake lines rust and often need complete renewal.
CV joint boots split through off-road use or age, allowing dirt to enter the joints and destroy them. A complete driveshaft replacement is expensive and more frequently required on off-road vehicles than on regular passenger cars.
Behind the headlight housings on Jimny models from 2005 onwards, trapped moisture causes rust in the bodywork that is often only discovered when the headlights are removed. Left untreated, it spreads to adjacent structural areas.
Reports & Tests
The third-generation Jimny is not a model pupil at the MOT. Brakes fail above average often. Springs and shock absorbers are criticised excessively frequently up to the third inspection. Rust appears from the fourth year.
