Suzuki 1.0 and 1.4 Boosterjet (familia de motores K: K10C and K14C/K14D)Timing chain
Timing chain: no documented pattern of failures on the 1.0 and 1.4 Boosterjet
Why this rating?
Low severity: A nuisance or wear. It does not immobilise the car or damage other parts.
Frequency rare: We reviewed the German TÜV inspection reports for the Vitara and the Swift with this engine and none of them flags the timing as a weak point; it does not appear either in the fiches-auto.fr owner testimonies for the Vitara or the Swift 3, or in the specialist press we consulted. With no documented cases, we do not treat it as an engine fault, only as something to keep an eye on, as with any timing chain.[3][4][5][6]
Symptoms
- This would be the expected symptom if the chain were to slacken or stretch, but none of the sources consulted for this engine describes it.[3][4]Chain noise: other faults that cause it · Garage soon
Why it happens
There is no cause to document: neither the TÜV inspection reports nor the owners we consulted describe faults with the chain, its tensioner or its guides on the K10C or the K14C/K14D.[3][4]
If it is not repaired: As there is no documented pattern, there is no consequence to describe beyond the general advice to keep up with oil changes, on which the life of any timing chain depends.[3]
Affected cars and years
The three engines in this guide (K10C, K14C and K14D) share the same type of chain-driven timing with twin camshafts; there is no documented reason to distinguish between versions.[1][2]
| Version | Years | Codes |
|---|---|---|
| 1.0 Boosterjet 110-112 hp (K10C, three-cylinder, 2015-present) | since 2015 | K10C |
| 1.4 Boosterjet 140 hp (K14C, non-hybrid, 2015-2020 in Europe) | 2015–2020 | K14C |
| 1.4 Boosterjet Mild Hybrid 129 hp (K14D, 48V SHVS, since 2020) | since 2020 | K14D |

How much it costs to repair
Includes: Diagnosis and a check for chain stretch; no replacement applies if no slack is detected.[3]
There is no cost to give because there is no documented fault to repair on this engine.
Prices in Spain, including VAT. A workshop hour costs on average €38–66 at independent garages and €77–134 at dealerships in Spain, depending on the region and the brand. How we calculate costs
How to check for it before buying a used car
- Start the engine from cold and listen for a few seconds: a metallic rattle that quickly disappears is not normal on any chain-driven engine, even though it is not documented on this one.
How to prevent it
- Stick to the manufacturer's oil change intervals: it is the measure that most affects the life of any timing chain.
Recalls, campaigns and claims
As of 27 September 2026, we have no record of recalls, campaigns or extended manufacturer warranties for this fault. Check with an official dealer using the chassis (VIN) number: they will tell you whether the car has any outstanding campaign.

Other 1.0 and 1.4 Boosterjet faults
- Low severityFrequency: RareLubricationOil consumption: no documented patternNeither the German TÜV inspection reports nor most owner testimonies describe high oil consumption on the 1.0 or the 1.4 Boosterjet; we have only found one isolated case, with no further detail, on a review forum.
- Low severityFrequency: RareInjectionDirect injection and fuel pump: no documented faults or recallsWe have not found any recall or pattern of failures of the high-pressure pump or injectors on the 1.0 or the 1.4 Boosterjet, unlike other small direct-injection turbo engines from other manufacturers.
- Low severityFrequency: RareElectronics48 V SHVS mild-hybrid system: no documented faults so farThe 48 V mild-hybrid system on the 1.4 Boosterjet (K14D) has been on the European market since 2020; we have not found sources documenting faults with its lithium battery or its starter generator in the time it has been on the road.
More faults with the timing chain on other engines and cars
- Critical severityFrequency: Very frequent1.5 BlueHDiWear and breakage of the 7 mm chain between the camshaftsIn 1.5 BlueHDi engines built between October 2017 and January 2023, the 7 mm chain linking the camshafts can stretch and break, causing serious engine damage. Stellantis has recalled them and covers the fault for 10 years or 240,000 km.Repair (garage): €730–€820
- Critical severityFrequency: Very frequent1.2 and 1.4 TSITiming chain stretch and tensioner failure (EA111)On the 1.2 and 1.4 TSI EA111 (2006-2015) the chain can stretch and the tensioner fall short; if the chain jumps a tooth, the valves hit the pistons. Volkswagen admitted the defect in 2012 and revised the chain and tensioner between 2010 and 2011.Repair (garage): €700–€1,400Appears at around 30,000 km
- Critical severityFrequency: Very frequentBMW N47Rear timing chain stretch and breakageYes: the N47 has its timing chain at the rear of the engine, next to the gearbox, and on a very high proportion of units, especially those built between 2007 and 2009, it stretches or breaks prematurely because of an inadequate tensioner, with a risk of destroying the engine.Repair (garage): €1,590–€3,000Appears at around 50,000 km
- Critical severityFrequency: Very frequentOM651Timing chain stretch and tensioner failureYes: the OM651 timing chain can stretch prematurely, above all on units built up to 2013, and in 2014-2015 Mercedes-Benz recalled around 114,000 vehicles in Germany over a defective sealing ring in the tensioner. A metallic rattle on a cold start is the first sign.Repair (garage): €2,000–€3,500Appears at around 120,000 km
- Critical severityFrequency: Very frequent2.0 Ingenium diéselTiming chain stretchYes: the timing chain on the 2.0 Ingenium diesel can slip or stretch prematurely and put the engine out of time, with a risk of serious failure. It is documented on the Evoque, Discovery Sport, XE, E-Pace and F-Pace, with engine failures between 90,000 and 130,000 km in several owner reports.Repair (garage): €4,000–€7,000Appears at around 90,000 km
- Critical severityFrequency: Common1.3 MultijetTiming chain stretch and tensioner failureYes: the timing chain's hydraulic tensioner can lose pressure and let the chain slacken; if it skips teeth or breaks, it can destroy the engine. It is a documented problem on Fiat, Opel, Suzuki and Ford cars with this engine, mainly linked to long oil change intervals.Repair (garage): €350–€550Appears at around 70,000 km
