The Suzuki 1.4-liter BoosterJet engine is a lightweight and compact engine. Furthermore, it provides great driving pleasure but it’s still economical. Nonetheless, what are the Suzuki 1.4 BoosterJet engine problems?

What are the common problems with Suzuki 1.4 BoosterJet engine?

Engine power loss

This is one of the common issues that users of the Suzuki 1.4 BoosterJet engine have reported. This problem is normally caused by fuel injector problems, resulting in insufficient fuel delivered to the engine. Alternatively, it can also be caused by a clogged fuel filter. 

No matter the case, you should have your car diagnosed. If the fuel injectors are damaged, they should be replaced. But if the fuel filter is clogged, it should be cleaned. 

Timing chain issues 

This is one of the most prevalent issues with the Suzuki 1.4 BoosterJet engine. One of the common signs of a bad timing chain is the engine rattling as it starts. If the problem is not taken care of, the sound becomes louder and more frequent.

Note that this problem could be caused by a failing timing chain tensioner or a bad timing chain. Have the car inspected and the issue fixed. To avoid this problem, ensure the car is properly maintained and with the right fluids and in good time. 

Clogged EGR Valve 

The exhaust gas recirculation valve controls the flow of exhaust gas being recirculated depending on the engine load. But after putting on several miles, the EGR Valve may become clogged and lead to reduced acceleration, reduction in power, and decreased fuel efficiency. 

To fix this issue, the clogged EGR valve should be cleaned or replaced if it’s damaged. 

Rough idling 

Rough idling in the Suzuki 1.4-liter BoosterJet engine is normally caused by clogged air filters, dirty fuel injectors, and bad spark plugs or ignition coils. This means that if you properly maintain the BoosterJet engine, you may not experience such issues. 

To fix this problem, you will have to visit a professional mechanic to diagnose and fix the underlying problem. 

Engine vibration 

Engine vibration can be caused by different things in the 1.4-liter BoosterJet engine. Some of the things that cause engine vibration are a broken timing belt or bad motor mounts. Motor mounts are designed to stabilize the car while driving. So, if the motor mounts are bad or damaged, the car will not stabilize and the engine will vibrate. 

To fix this issue, the owner will have to visit a professional mechanic for diagnosis and repair. Replace the faulty parts to fix this problem. 

Oil leak 

One of the most overlooked problems with the Suzuki 1.4 Booster Jet engine is the oil leak. Some of the reasons why oil leaks in this engine are due to a cracked cylinder head in the engine, crankshaft oil seal failure, and leakage around the gasket of the timing chain.

Faulty drive belt tension pulley 

Apart from having timing chain issues, the Suzuki 1.4-liter BoosterJet engine also experiences a faulty drive belt tension pulley. And like the timing chain, this problem is also caused by a lack of proper maintenance of the engine. If this issue is not fixed, the user might see a warning light on the dashboard.

The best way to avoid this problem is by following the manufacturer’s recommended maintenance schedule. Nonetheless, if the drive belt tension pulley is damaged or faulty, it will have to be replaced.

What is the fuel consumption of the Suzuki Vitara 1.4 BoosterJet engine?

The Suzuki Vitara 1.4 BoosterJet engine is a very efficient car. Even with a top speed of up to 200km/h, the 2018 1.4-liter BoosterJet engine has a combined fuel efficiency of 6.1 liters per 100km. Furthermore, it has a fuel efficiency rating of 7.0 liters per 100km in the city and 5.5 liters per 100km on the highway.

What makes the BoosterJet engine unique from other Suzuki engines?

The BoosterJet engine is unique because it can burn a greater amount of fuel-air mixture in a certain period. On top of that, output can be increased without raising the size or displacement. This is all thanks to the turbocharger that the BoosterJet engine is fitted with.

The turbocharger uses the energy of the exhaust gases to drive turbines and force-feed compressed air into cylinders. 


The Suzuki 1.4 BoosterJet engine may be a compact and lightweight engine with exceptional performance, but it also comes with several problems. To avoid having several engine issues and spending more time in the garage, the owner should properly maintain and repair their engine.
