Kia Problems

Some oil consumption is normal for engines, and modern engines seem to use a little more than some older designs. That's because modern engines are designed with low-friction piston rings which are great for fuel economy but can lead to slightly higher oil consumption. However, 700ml per 1000km does seem high for what is not an especially high-performance engine, and one that has not travelled very far in the scheme of things.

It wouldn't be the first time a dealer (of any brand) has tried to fob off a customer concern with such a response, so I reckon you're on the right track by contacting Kia Australia's customer service division. I'd also follow up with a phone call as well as an email, but experience suggests Kia is one company that takes customer satisfaction seriously.

Your car is still covered by the factory seven-year warranty, so provided it's been serviced correctly, if there is a fault, it should be covered. Further investigation is warranted, including a compression and leak-down test to show if there's any deterioration in the performance of the engine's piston rings. Your local state motoring club is a good source for these tests, particularly as manufacturers tend to take the clubs and their mechanical inspections seriously.

The 2021 Sportage range covers a variety of towing capacities depending on what engine and transmission are fitted and whether the example in question features all-wheel-drive or front-wheel-drive.

So, in no particular order, the Sportage with front-wheel-drive can tow up to 1600kg with a braked trailer, the AWD petrol can tow 1500kg, the AWD diesel has a towing maximum of 1900kg and the facelifted 1.6-litre petrol with the dual-clutch transmission can cope with 1650kg (all with the same braked trailer).

With a trailer with no brakes, the maximum towing capacity for any 2021 Kia Sportage is 750kg.

The allowable maximum tow-ball weight for the Sportage will have been calculated by Kia using all the available information from the car's weight distribution to the spring rates, the ride height and wheelbase measurements and even the way the rear structure of the car is physically constructed. So that's what you should stick to and, yes, 100kg is the official tow-ball weight for this vehicle.

The theory that holds that tow-ball weight should be 10 per cent of the towed weight (while the reality for a lot of makes and models) is really just that; a theory, a rule of thumb, and definitely not a hard and fast rule. As such, there's nothing to force car-makers to stick to it. Which is why Kia hasn't for the Sportage.

There's another school of thought in other countries that the tow-ball weight should actually be closer to five per cent of the towed mass, at which point the Kia's limit starts to make more sense.

This situation will turn out very differently depending on whether the car is still under Kia's factory warranty, or an aftermarket warranty sold by the dealership when the car was bought by your daughter. It will also depend on whether the cracked transmission case was due to a flaw or something thrown up off the road (which would count as accidental, not warranty, damage).

Kia extended its factory warranty to new, privately-owned cars on October 1, 2014. Which means the car in question was covered to that extent. With that in mind, the car should, indeed, be covered by Kia's factory warranty (until next year) so there should be no quibbling about a failure like this one that has had nothing to do with the way the car has been used or serviced. My experience is that Kia is pretty good at this stuff, figuring that its long-term reputation is more valuable than fixing an – often – rare fault. And even though your daughter was not the first owner of the car, the factory warranty is transferable to subsequent owners. Provided, that is, that the car has been serviced and maintained correctly.

If, however, the car is covered only by the aftermarket warranty, then you'll be in for a huge fight as these aftermarket warranties are rarely worth the paper they're printed on. The fine-print is full of clauses and conditions that allows the car dealer to wriggle out of their responsibility, and we simply don't recommend these warranties under any circumstances.

As for the fault itself, it's pretty rare to hear about something like a transmission case fracturing. Perhaps there was a manufacturing or casting flaw in that particular unit that has taken its time to surface and cause the failure. As for what you should do, the answer is simple: Take it back to the dealership you bought it from and make sure it's fixed properly according to the terms of Kia's own warranty. Don't be afraid to be a bit patient, and always give the dealership (or Kia) every chance to put things right before you instigating legal action or contacting the ACCC.

If Kia expresses any doubt over what caused the failure, an independent inspection (perhaps by the NRMA) will be able to determine what caused the casing to fracture and, therefore, whether it's a warranty or insurance job.

The smart money says go with a Toyota. The RAV4 is popular but within your budget, you'll be buying a 12- or 14-year-old car with at least 200,000km on its odometer. Which still means it's probably a pretty good thing in terms of reliability, provided it's been serviced correctly up to now, but you'd have to buy carefully. A second-hand Kluger can also be a good deal if you can afford the fuel, but comes with the same caveats.

A Honda CR-V won't be much different to the RAV4 in terms of its price versus model year, but you stand a slightly better chance of finding a CR-V with relatively low kilometres. Don't be afraid to get a bit alternative and look at things like the Kia Sportage. Your ten-grand gets you into a Sportage of around the same vintage as the RAV4, but is likely to have as many as 100,000 fewer kilometres on board. Again, check for a full service history.

And given your usage pattern, don't be temped to stump up more for a hybrid SUV; there's just not the pay-off at the pump for a car that does mainly highway and open-road work.

There are two things you need to do. The first is to have the vehicle independently inspected. The RACV is very good for this as it has the resources and a reputation that the car industry respects. Once you've found out what really went wrong (as opposed to what the dealership may have told you on the spot) you can proceed. This will inform what happens next.

If the engine failure was not the cause of a poorly fitted oil filter and was something to do with a manufacturing or materials flaw, then you have a case for a warranty claim. Bypass Kia's dealer network and contact the brand's customer service division at head office.

If, however, the failure was caused by a lack of attention by the mechanic who carried out the last service, then the responsibility may rest with them. Mechanical workshops often have insurance to cover them against this sort of mistake but, regardless, if your mechanic was at fault, the problem becomes theirs in many cases.

A modern vehicle like the Kia has a range of engine protection and warning systems to prevent this sort of thing happening. It seems strange that you didn't receive a dashboard warning regarding low oil level or low oil pressure in the moments before the engine failed.

All Kias sold in Australia and built after 1996 can use E10 fuel. But your car will be just as happy on standard ULP with its 91 RON octane rating.

You won't notice any difference between the two fuels apart from perhaps a slightly higher fuel consumption when using the E10. That's because the ethanol content of the fuel has less energy in it than normal petrol. But there's really not much in it and the extra E10 you'll use will be offset by the cheaper per-litre cost compared with ULP.

The fact that you've used E10 will not alter the retained value or desirability to of your car to a potential buyer one bit.

This could be a coincidence whereby your maintenance was timed perfectly with something else going wrong. But if we assume that the new fuel filter is what has caused the no-start condition, then the first thing to check is that you've installed the filter in the correct orientation. Many filters only operate in one direction. Install it backwards, and the fuel may not flow at all, which would give you the symptoms you're now looking at.

It sounds like a pretty nitty-gritty tech question, but is the camshaft in the engine of the Kia Rio timing belt or chain driven? There’s a good reason for knowing the answer, though, as it determines whether you need to add a crucial routine maintenance step to your ownership.

In cars with a toothed rubber timing belt, the belt and its tensioners need to be changed at an interval recommended by the car’s manufacturer to avoid expensive belt failures which can ruin the whole engine. Ignore this maintenance at your peril.

The good news is the GL4C engine as used in the Kia Rio since 2016 uses a timing chain which should be good for the life of the engine and not need any extra maintenance.

A shaking through the steering when you apply the brakes is often caused by brake rotors which have warped. Imagine spinning a bicycle wheel with a buckle in it. In a micro sense, that's what a warped brake rotor is doing. When that happens, they fight against the force of the brake calipers and that leads to the shaking you're feeling. You're right not to feel safe as the car is definitely not safe in this condition.

Sometimes the brake rotors can be machined to make them true again, but other times a replacement set of rotors is the fix. Don't forget to get your mechanic to change the brake pads when they fit the new rotors, as new rotors can be compromised by old pads.
