Hyundai I30 Gearbox & Transmission Problems

Depending on what sort of noise the transmission is making, this sounds like a broken or worn out clutch. Without a properly functioning clutch, gears can be extremely difficult to select and can also cause horrible graunching, grinding noises when trying to select any gear, but particularly reverse.

If this is, indeed, the problem, you could be looking at thousands of dollars to remove the transmission, replace the clutch and reassemble the driveline. You might even find that the engine's flywheel is also beyond saving and needs replacing, too.

On the other hand, the lazy clutch could be a simple case of a leaking or worn clutch slave or master cylinder or even a poorly adjusted clutch system which is allowing the clutch to disobey what the clutch pedal is telling it to do. If that's the case, the fix could be quite simple and relatively cheap.

The point is that you need to know what the problem is before handing over the money, because the value of the same car with either problem will be vastly different. Perhaps finding a car with a properly working clutch and driveline is a better option.

A Golf with that mileage after just three or four years on the road is a bit of an anomaly. How has the car been used? Was it a delivery vehicle in a previous life? I’d be asking some tough questions and diving deep into the vehicle’s service history to find out how it’s been driven and serviced before taking the plunge, because that mileage is about double what I’d expect from this make and model.

The biggest potential reliability glitch with this car is the DSG transmission. While VW claimed that all the evils were fixed by the time the Golf 7 came out in 2013, experience suggests that there are still some examples of this gearbox giving trouble. Symptoms include a loss of drive, poor shift quality, shuddering on take-off and a gearbox that seemingly loses the plot on occasions.

And I’m afraid your alternative rings a few alarm bells as well. The Hyundai also uses a double-clutch style transmission and while it hasn’t suffered the litany of problems that the VW unit has caused over the years, it’s still a bit of an unknown quantity. Certainly, some customers seem to be unhappy with the unit in terms of its longevity and replacement clutch packs are not unknown.

Also, you seem to have a knack for finding cars with double the expected kilometres on board. I’d expect a 2018 i30 to be showing closer to 25,000km than the 50,000km on the one you’re considering. Cars with higher than expected mileage can be bargains, but you’ve really got to dig into their past to ensure they haven’t been abused or suffered from poor servicing.

On the surface it does seem unreasonable that the new transmission is not covered by the warranty. I would press Hyundai for an explanation of the problem, and an answer as to why the replacement transmission isn’t covered. If that doesn’t get a satisfactory response I would contact the Consumer Affairs people in Victoria and enlist their help.

Clutches do wear out and need to be replaced, and you will need to do that in the future when yours wears out. The mileage you quote is within the normal range.

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.

All production Hyundai i30s are front-wheel drive.The Korean manufacturer has other rear-wheel drive and 4x4 models in their range, although some enterprising teams custom-built 4x4 i30 rally cars for use in motorsport.

Were you able to demonstrate the problem to the dealer? If not go back and do that, so that they know what it is you are unhappy about. That way they might be better equipped to fix it. It could be a problem with the calibration of the computer controlling the transmission, or it could be an internal problem with a clutch or the oil pressure within the transmission.

Unless you are buying a manual I would rule the Cruze out, the automatic is trouble in that model and not worth the risk. If you do but a Cruze I would choose the 1.8-litre engine. Others to think of are the Hyundai i30, Mazda 3, or Mitsubishi Lancer.

It's probably easier to eliminate those that don't stack up, those being the VW Golf, Holden Cruze and Ford Focus.

All have transmission questions over them.

The best options would be the Mazda 3 and the Hyundai i30.

I'm guessing you will want the problem fixed under warranty, so you will have to go to a Hyundai dealership. Go to a big dealership, which should be able to do the job for you, or if you are not confident call Hyundai and ask for a list of dealers who can do it for you.
