Kia Problems

This very website has an absolute wealth of information on this topic. Follow this link: https://www.carsguide.com.au/kia/cerato/2016 and you’ll find everything from pricing guides to performance data, dimensions and even towing capacities. It’s all there in black and white and one of the reasons CarsGuide is the best in the business.
 

I wouldn’t be taking the car to a transmission specialist…yet. Since the car is still under warranty, you need to give Kia every chance to sort it out for you. The good news is that this won’t cost you a cent, whereas taking it to an independent repairer will start emptying your wallet.

You’re doing the right thing by keeping a close watch on the transmission temperature readings (provided that’s not at the expense of watching the road) and if overheating was what caused the warning light to illuminate, then I’d be of the view that the transmission fluid should be changed (at the very least) and an investigation carried out into why the transmission overheated in the first place.

I haven’t heard of a rash of problems with the Rio GT-Line’s seven-speed DCT transmission in Australia, but Kia’s DCT gearboxes in other models have been known to give problems in other countries. Given our typical summer ambient temperatures, we probably won’t be immune from the same problems. This is not a Kia thing, by the way, but seems to be one of many problems that have plagued DCT (double-clutch) gearboxes over the years from a variety of car-makers.

The clutch packs in these gearboxes have to slip to work and that’s a well-known cause of heat in any transmission. If they slip enough, they could conceivably cause the transmission to overheat at which point it will trigger the warning light you’re seeing as well as not operating properly and potentially doing internal damage. Both Ford and Volkswagen have discovered this the hard way, replacing many double-clutch transmissions under warranty over the years.

It’s a bit hard to see why so many manufacturers are persisting with this technology, especially when the modern, multi-ratio conventional automatic is so compact, light and efficient these days.

There are still plenty of great small cars around within your budget, Agnes, and they all have good safety packages (or we wouldn’t recommend them). Look at offerings such as the Suzuki Swift Navigator (with the optional autonomous emergency braking) for around $17,000 (plus on-road costs) or the Kia Rio S at around $19,000 or Kia Picanto S (one size smaller than the Rio) at closer to $16,000. Both the Kias also feature the brand’s excellent seven-year warranty, capped-price servicing and free roadside assistance which is great peace of mind.

The Volkswagen Polo is a classy drive but a little more expensive at closer to $21,000 for the 85TSi Comfortline. Actually, to be honest, you’ve missed the boat on bargain small cars by a couple of years. Firm favourites such as the Toyota Yaris and Mazda 2 have both been updated relatively recently and have recorded big price jumps in the process. The cheapest Yaris with an automatic transmission is now around $23,000 (it was less than $17,000 back in 2018) while the Mazda 2 Maxx went from being a sub-$17,000 proposition in 2018 to a $23,000 car by the time you add an automatic transmission in 2020.

The answer will come down (somewhat) to whether the car dealership you buy from wants your car as a trade-in or not. Even if it’s agreed that your Sportage will act as a trade-in, if the car yard in question doesn’t really want it, they won’t offer you much for it. Sometimes, a car dealer will even give you what’s called a no-trade bonus which is a few dollars off the price of the new car on the basis that you’re not lumbering them with a trade-in they don’t want to have to sell on.

You stand to make a little more by selling the Sportage privately, but only if you can be bothered with placing an advert and then having a stream of strangers in your driveway on a Saturday morning. Trading the old car in on the new one is the simplest, easiest way of switching cars, but as with any deal like this, don’t be star-struck by the trade-in price, because the extra you think you’re being given for the car will almost certainly be added on to the price of the new car. The important number with this type of transaction is the change-over figure; the actual amount of money you need to stump up to swap from one car to another.

The Kia Sportage sold in the US certainly did have its share of problems. In some cases, the engine failures were traced to a faulty batch of engine bearings, in others, a leaking oil sump was blamed for allowing too much oil to escape, leading to oil starvation which destroyed the whole engine. Kia’s fix for the latter condition was to fit an oil-pressure warning light with a more proactive trigger-point.

But it’s dangerous to assume that the same make and model sold in the USA (or anywhere else) will have the same problems as Australian delivered cars. Often, even though they share a brand and badge, the cars from different markets are built in different factories and use parts from different suppliers. Sometimes there are major mechanical changes to cope with local conditions and tastes which can lead to very different reliability outcomes.

That said, however, the Theta engines used in local Kias have been problematic for some owners and catastrophic engine failures are part of those. You could talk with Kia Australia’s customer service division about financial assistance with the cost of repairs, but at nine years old – even with relatively low kilometres – there would be no guarantee of that happening. 

It sounds as though there’s some slack somewhere vin the driveline that is taking up suddenly with a clunking noise as the result. This is actually pretty common in cars as they age and relates to general wear and tear on the driveline components.

What you haven’t told me is whether your car is a petrol or diesel model which will determine whether it’s a front-wheel-drive or all-wheel-drive vehicle respectively. Why does that matter? Because, fundamentally, the all-wheel-drive version – which has a centre differential, a transfer-case and a driveshaft for each wheel – has more than double the driveline components of the front-drive Sorento. And, clearly, that means at least double the opportunity for a clunk or creak or groan to creep in as the vehicle ages.

Regardless of the driveline layout, of course, any free-play in the driveline is bad news because it means there’s wear somewhere and that needs to be identified and fixed before it wears further and, ultimately, fails, leaving you stranded or even contributing to a crash. So have it checked by a workshop familiar with that make and model and nip any problems in the bud while they’re still annoyances rather than catastrophes.

In the meantime, you can do a bit of detective work of your own: Many driveline clunks are caused by worn CV (Constant Velocity) joints which allow the wheels to turn (with the steering) as well as drive the car. Find a nice, deserted car-park and slowly drive in circles first with full left lock and then with full right lock. You’re listening for a clattering, clicking or rumbling noise as you do so. If you can hear such a noise, then you might just be well on your way to diagnosing the problem.

Mazda’s SUV range (CX-5 and CX-8) are popular with their owners and have a good reputation in the trade. Crucially, they’re also available with a turbo-diesel engine, so they fit your criteria on that basis. We’d also suggest you take a good look at the South Korean brands’ offerings (Hyundai and Kia) as these are also highly rated by the trade and those companies have been involved with small-capacity diesel engines for decades, so the technology is pretty well sorted.

It’s interesting that you’ve had a good run from your Holden Captiva as that is far from the experience of many owners and former owners of this particular vehicle. As the Captiva ages it is very likely to start giving trouble, so the best advice is to trade up to a newer vehicle sooner rather than later.

It sounds like something electronic is randomly playing up and that’s causing the intermittent problem. Modern engines like these use a raft of sensors to keep the on-board computer informed of what’s going on and keep everything running smoothly and efficiently. If just one of those sensors stops working properly, all sorts of havoc can result.

It’s a bit strange that the on-board diagnostics of the vehicle aren’t throwing up a relevant fault code when your mechanic interrogates the computer but, again, some of these modern electronic systems require some pretty specific software. Which means a trip to a Kia dealership might provide a more in-depth answer to what’s going on.

The good news is that since 2014, Kias sold new in Australia have been covered by a seven-year warranty, so your Sorento is well and truly still under that factory cover. Which means it shouldn’t cost you anything to have the problem sorted out by Kia.

This is a real problem and many road service call-outs are, in fact, caused by this very problem. It’s vastly more common for petrol to be put into a diesel vehicle than the other way around, simply because a petrol bowser nozzle will fit into the diesel car’s filler neck, but not the other way around. But should you mistakenly put petrol into a modern, common-rail diesel engine, the entire fuel system needs to be cleaned as a result. And that’s the best-case scenario, because if you drive any distance with petrol in the system, repairs can top $10,000 in some cases.

The devices you have listed usually work in the same way; they replace the car’s standard filler neck and act as a physical barrier to an unleaded petrol nozzle being inserted into the car. Unless the nozzle being presented is a diesel-sized nozzle, you won’t be able to put anything into the tank. Installed correctly, they should present no problems, but as with any part of a car’s fuel system, the installer needs to know what they’re doing. But they’re popular with fleet vehicles (which are driven by a variety of people who may or may not know the vehicle is diesel-powered) and families with a fleet that uses more than one type of fuel.
