Hyundai i30 Engine Problems

What is causing my 2013 Hyundai i30's rough cold start?

Answered by CarsGuide 7 Sep 2021

Any smoke from the exhaust of a car suggests there’s something wrong with the fuel system or that there’s wear inside the engine. I’m leaning towards the fuel system in this case, though, as a cold-start is when the fuelling system is under the greatest stress.

To make a cold engine run properly, the engine’s fuel-air ratio has to be altered (more fuel and less air than when the engine is up to temperature). To know how much extra fuel, the engine has a range of sensors that measure the temperature of the air going into the engine, the temperature of the engine itself, the flow of air, as well as sensors that sniff what’s coming out of the tailpipe to make sure the mixture is just right. If any of these sensors begin to send false information to the engine’s computer, the mixture can be incorrect and the rough running, poor idling and visible smoke can be the results.

Even something as simple as the stepper-motor, which controls the idle speed of the car, can be the cause of rough idling, but that’s less likely to contribute to gales of smoke from the exhaust. The best advice is to have the car scanned and see if the computer has logged any faults. Smoke from the engine might also warrant a compression test of the engine’s cylinders, too. From there, you can make a more informed diagnosis and replace only the faulty parts.

Why is my 2020 Hyundai i30 misfiring?

Answered by CarsGuide 24 Mar 2021

This sounds like a problem that should be easily solvable by having your Hyundai dealership electronically scan the car and interpreting the fault codes that result. This can’t be done by the side of the road or in your driveway, so I doesn’t surprise me that your road-service provider hasn’t had much success.

Fundamentally, though, it’s simply not good enough for the dealership to continue to tell you it can’t find a problem. This is a brand-new car and it’s expected to perform faultlessly or, at the very least, to a standard that does not give your partner cause to refuse to drive it. The car is under warranty, so Hyundai is obliged to fix it. If you’re not happy with your dealership’s approach, I’d suggest calling Hyundai’s customer service department. Hyundai guards its reputation very closely in Australia, and isn’t likely to let a case like yours damage that.

Does my 2012 Hyundai i30 petrol need a timing belt change at 100,000km?

Answered by CarsGuide 10 Mar 2021

Petrol versions of the Hyundai i30 from this era have a rubber, toothed timing-belt. This is a clean, quiet running arrangement, but it does require replacement at 90,000km intervals. The advice is to change the tensioners, associated pulleys and the engine’s water pump at the same time as all these components wear out and are located in the same general area, making it a smart move to do all this work in one hit, rather than pull the engine apart a second time.

Does the 2.0-litre engine in a 2012 Hyundai i30 have a timing belt or chain?

Answered by CarsGuide 18 Sep 2020

The engine in your car uses a rubber timing belt which requires replacement every 90,000km. The design of this engine means a broken timing belt will likely destroy the entire engine, so it’s not something to ignore.

Does a 2010 Hyundai i30 have a timing belt or chain?

Answered by CarsGuide 22 Aug 2020

The Trophy version of the i30 used exclusively the two-litre petrol engine. As such, it actually has both a timing belt and a timing chain. The engine has twin overhead camshafts, but only the exhaust camshaft is driven by the timing belt from the crankshaft. A short timing chain then takes drive from the exhaust camshaft to the intake camshaft. The engine also features variable valve timing.

The good news is that you really only have to periodically replace the timing belt (the chain should be maintenance-free for the life of the engine). The recommended replacement interval is every 100,000km.

Hyundai i30 2010: Why can I smell exhaust fumes in my car?

Answered by CarsGuide 7 Aug 2020

This needs to be fixed fast, Toni, as a car’s exhaust fumes are a deadly cocktail of gasses. Enough exposure to them can make you pass out (an obvious problem when you’re driving) or worse. Diesel engines are generally a bit smellier than a petrol engine, but no exhaust fumes should ever enter the car.

You’re either getting fumes drawn into the car via a faulty seal that is allowing exhaust fumes in, or the smell you’re experiencing is fumes in the engine-bay coming through the firewall. You need to inspect all the rubber seals around the doors and hatchback and search underneath the car and in the engine bay for a split or missing rubber bung or grommet that is letting the outside in.

The other question I have is whether the smell is the result of exhaust fumes or, in fact, the smell of unburnt diesel fuel. Diesel cars often acquire a diesel-fuel smell over time and the cause is hard to avoid. Because diesel doesn’t evaporate, the ground around the diesel pump at a service station is usually one big oily, diesel slick. When you fill your car, you unavoidably stand in this slick which is then transferred to the car’s carpet when you get back in. It’s not as crazy as it sounds, and it may be the clue you’re missing to explain the smell.

My Hyundai i30 is blowing smoke

Answered by CarsGuide 27 Apr 2018

You don’t say if it’s a petrol or a diesel, but no, it’s normal, although there are reports of smoke from the i30. If it was a diesel I would suggest there is a problem with the turbocharger, but something is clearly wrong and you are right to have it checked, particularly as it is still under Hyundai’s new car warranty.

Hyundai i30 2009: Any problems with the engine or gearbox?

Answered by CarsGuide 13 Apr 2018

There is nothing to suggest that you will have any serious problems with it in the near to mid-term future, as long as you look after it and service it regularly. It sounds like a keeper, so if you like it keep it.
