Honda Jazz
1.3L i-DSI with 2 spark plugs per cylinder (8 in total), which raises servicing costs. EGR valve carbon build-up is the most common problem. CVT gearbox with wrong factory oil is a frequent cause of shudder on shifts.
City king with no motorway gene
1.3 i-DSI in the Jazz: complex but refined. Agile and nimble in town; hills and overtaking make it pant. Adequate for small-car city life, nothing more.
Engine Weaknesses 3
The EGR valve can stick open due to carbon deposits, causing excessive exhaust gas recirculation, hesitation, and stalling at idle. Regular cleaning is recommended.
Symptoms: Hesitation or stalling at idle, increased fuel consumption, rough idle
Honda filled the CVT from the factory with ATF-Z1, which has since been superseded by ATF-DW1. The wrong fluid causes judder on pull-away. Regular fluid changes with DW-1 fix the problem.
Symptoms: Judder or vibration when pulling away from a standstill, jerky CVT power delivery
The i-DSI system uses 2 spark plugs per cylinder (8 total). Maintenance costs at spark plug replacement intervals are twice as high as on a standard 4-cylinder engine.
Symptoms: Rough running, misfires, noticeable judder during the warm-up phase
Vehicle Weaknesses 5
On early 2002/2003 model years, ABS modulator units fail more frequently. Primarily affects first-production vehicles, which has safety implications.
Rust forms on the lower door edges and tailgate of older examples. The door seals become porous and allow water ingress, accelerating rust.
The air conditioning fails frequently — typical causes are a defective relay, the compressor magnetic clutch, or the compressor itself. Repairs are costly.
The anti-roll bar drop links wear at higher mileage and cause rattling from the suspension. The suspension tuning is also fundamentally firm and offers little comfort.
The brake shoes of the rear drum brakes get contaminated and cause uneven braking. Regular cleaning and inspection are needed to avoid MOT failures.
