1.2 / 1.4 / 1.8 i-VTEC engine: faults and reliability

Honda 1.2 / 1.4 / 1.8 i-VTEC e i-DSI (L12/L13/L15/R18) · Honda

A family of naturally aspirated Honda petrol engines with a timing chain (no belt to replace). The L-series blocks (1.2 and 1.3/1.4, sold as the "1.4") and the R-series (1.8) have a reputation for robustness. The documented weak point is not the engine block but the i-SHIFT automated gearbox of the Jazz II and Civic VIII, along with the clutch and flywheel, which wear out sooner than expected.[1][2][3][4]

Which 1.2 / 1.4 / 1.8 i-VTEC versions should you buy?

Our verdict for each version, based on the documented faults.

  • 1.4 i-DSI 83 (L13A1, Civic VII and VIII)

    2005–2009 · 83 hp · L13A1

    Buy

    We have not found a fault pattern specific to the i-DSI block in the sources consulted: it is mechanically simpler than the i-VTEC (no variable valve timing actuators) and shares the timing chain of the rest of the family. Because of its limited sales in Europe it also has the fewest owner reports, so the assessment rests more on its mechanical simplicity than on an extensive track record.[1][6]

  • With caution

    The block itself shows no clear pattern of serious faults, but a good share of the Jazz II and Civic VIII units were sold with the i-SHIFT automated gearbox, whose actuator fails repeatedly according to the reports consulted, and several owners also document early wear of the clutch and flywheel. It is worth checking the gearbox type and the clutch history before buying, especially on the Jazz II and Civic VIII.[3][4]

  • 1.2 i-VTEC 90 (Jazz II)

    2008–2015 · 90 hp

    Buy

    It is the Jazz II variant with the fewest issues in the Fiches-auto.fr reports: it is not associated with the i-SHIFT gearbox failures (documented on the 1.4) or with clutch problems, and only isolated cases of oil consumption or a radiator leak are cited.[3]

  • 1.3 i-VTEC 102 (Jazz III)

    2015–2018 · 102 hp

    Buy

    Fiches-auto.fr records a very positive assessment of the Jazz III (15 positive opinions against 2 negative) and, for this engine, cites only one case of a dirty EGR valve and another of injectors with an unstable idle; there is no sign of the gearbox or clutch problems that do affect the Jazz II.[7]

  • 1.5 i-VTEC 130 (Jazz III)

    2018–2020 · 130 hp

    Buy

    The reports collected by Fiches-auto.fr are few (6 cases) but without serious issues; only one case of noise related to the variable valve timing phaser is mentioned. With so few reports, the assessment is cautious because of the lack of track record, not because of problems found.[7]

  • 1.8 i-VTEC 140 (R18A2, Civic VIII)

    2006–2011 · 140 hp · R18A2

    With caution

    It is the engine with the most reports in the whole Civic VIII (92 cases, 127 positive ratings against 25 negative) and the block itself does not concentrate serious faults, but it shares with the rest of the Civic VIII range the i-SHIFT gearbox and clutch/flywheel failures, and units built between 2008 and 2010 fall within the technical notice on the water pump pulley.[4][8]

  • 1.8 i-VTEC 143 (R18Z4, Civic IX)

    2012–2017 · 143 hp · R18Z4

    With caution

    None of the 28 owners' reports collected by Fiches-auto.fr describes a serious engine failure, but high oil consumption (0.2-0.8 l per 1,000 km) associated with piston ring wear is common, and the rings were replaced under warranty in at least one case at 45,000 km; it is worth monitoring the oil level between services.[9]

  • It is the best-rated variant of the whole family in the reports consulted: Fiches-auto.fr describes it as the most reliable Jazz II, with a single documented problem (the battery cooling fan) at 12 years and 150,000 km. Consumer Reports even named the Insight the most reliable model in its 2010 comparison, although Honda later extended the engine warranty over excessive oil consumption in some units.[3][10]

  • 1.2 i-DSI 78 (L12A, Jazz I, 2002-2008)

    2002–2008 · 78 hp · L12A

    With caution

    Gebrauchtwagenberater.de notes, for the Jazz GD in general, that the EGR valve can carbonise and stick open, causing jerking or stalling at idle, which often ends in worn spark plugs and coils. We have found no reliability data specific to this capacity.[11]

  • 1.4 i-DSI 83 (L13A, Jazz I, 2002-2008)

    2002–2008 · 83 hp · L13A

    With caution

    Gebrauchtwagenberater.de notes, for the Jazz GD in general, that the EGR valve can carbonise and stick open, causing jerking or stalling at idle, which often ends in worn spark plugs and coils. We have found no reliability data specific to this capacity.[11]

  • 1.5 VTEC 111 (L15A1, Fit/Jazz I, 2002-2008)

    2002–2008 · 111 hp · L15A1

    With caution

    Gebrauchtwagenberater.de notes, for the Jazz GD in general, that the EGR valve can carbonise and stick open, causing jerking or stalling at idle, which often ends in worn spark plugs and coils. We have found no reliability data specific to this version.[11]

Buy: No known serious faults, or they have already been corrected, in this version. With caution: Worth buying if something specific is verified: history, a replaced part or a completed campaign. Avoid: High risk of a serious fault that is hard to check for or prevent.

Known faults of the 1.2 / 1.4 / 1.8 i-VTEC

Sorted from most to least important (severity × frequency).

  1. 1High severityFrequency: CommonTransmissioni-SHIFT automated gearbox actuator failureYes: the i-SHIFT gearbox (a single automated clutch) in the Jazz II and Civic VIII fails repeatedly at its electronic actuator, between 95,000 and 180,000 km; in the worst case, the repair was not worth it against the car's value. Honda also updated the software for a separate reverse-gear fault.Appears at around 95,000 km
  2. 2High severityFrequency: CommonCoolingLoosening of the water pump pulley and accessory belt failureOn the Civic VIII built between 2008 and 2010, the water pump pulley can work loose and break the accessory belt, with loss of power steering and battery charging; Honda documented it as a technical notice for those production years.
  3. 3Medium severityFrequency: CommonClutchPremature clutch and flywheel wearYes: several Jazz II owners and, above all, Civic VIII owners document early clutch and flywheel wear, with replacements as early as 35,000-90,000 km and the odd case of total failure while driving; it is the mechanical fault that recurs most in the reports for these two cars.Appears at around 35,000 km
  4. 4Medium severityFrequency: CommonLubricationOil consumption from piston ring wearThe 1.8 i-VTEC in the Civic IX (2012-2017) can burn more oil than normal, between 0.2 and 0.8 litres per 1,000 km according to the owners consulted, because of piston ring wear; Honda has replaced this part under warranty in at least one case from 45,000 km.
  5. 5Medium severityFrequency: OccasionalIgnitionSpark plug working loose on the 1.4 i-VTEC engineSeveral 1.4 i-VTEC owners, in both the Civic VIII and the Civic IX, document a spark plug working loose in its seat (in one case it was ejected from the cylinder head while driving); the cases are few, but the same symptom recurs in two different generations.

What the 1.2 / 1.4 / 1.8 i-VTEC is

Honda introduced this family of naturally aspirated petrol engines in 2001 with the launch of the Honda Jazz, and kept it going with various updates until around 2020, spread across the Jazz (second and third generation), the Civic (seventh, eighth and ninth generation) and the Insight hybrid. The first blocks used i-DSI (Intelligent Dual and Sequential Ignition) technology, with two spark plugs per cylinder firing at different moments to improve combustion; from the mid-2000s Honda gradually replaced them with i-VTEC technology, with variable valve timing.[1][12]

Unlike other engines of its era, the whole family uses a timing chain instead of a rubber belt, so it does not need this component replaced periodically. The 1.2 and 1.3/1.4-litre block (L series) is a naturally aspirated four-cylinder, like the 1.8 (R18 series), which is somewhat larger and reserved for the Civic. The Insight hybrid uses a variant of the same architecture (LDA), of 1.3 litres, combined with a small electric motor from the IMA (Integrated Motor Assist) system.[1][2][10]

One Honda quirk complicates the search for information on this engine: the 1,339 cc block was sold in Europe as the "1.4 i-DSI" or "1.4 i-VTEC", even though its real displacement is 1.3 litres. In this text we use the commercial designation ("1.4") unless stated otherwise.[13]

Most units were sold with a manual gearbox, but the Jazz II and the Civic VIII also offered the i-SHIFT, a single-clutch automated gearbox (not a conventional automatic) designed to cut costs compared with a classic automatic. It is precisely in this gearbox, and not in the engine block, that this family's most repeated faults are concentrated.[3][12][14]
