I can understand why the crank angle sensor was the first thing to be changed. These often start to die and the first symptom is an engine that stops after running for a while. But you’re right to be sceptical about the timing chain as there’s a theory that says if the engine runs properly at all, then the issue won’t be anything fundamental. Which is to say, if the timing chain was stretched beyond the point at which the engine could function properly, it wouldn’t function properly at all, regardless of how long it had been running.
A good workshop should be able to scan the car’s computer. If the timing chain really is stretched, then the computer should have logged this as a problem. If not, then you’re looking for something else. Of course, what that something else is the million-dollar question. Don’t rule out basic things like a dirty fuel filter which can allow fuel to flow for a while before the rubbish in it clogs the flow after a few minutes running.
That said, if the engine can’t locate the correct signal from the camshaft (which is controlled by the timing chain) it will sometimes look for a stand-in signal somewhere else on the engine, allowing it to start but not run properly. An electronic scan is definitely the way forward.
These modern active cruise control system rely on lots and lots of information from around the car to function properly. And unless all those camera, steering, braking and throttle position (and more) sensors are playing as a team, the car’s computer - acting as the onboard relationship manager - has no option but to disable some functions, as they become potentially flawed without the correct inputs.
That’s why the connection between the power steering and the cameras on your car is so critical, and also why the systems have shut down. The actual failure could be with either the steering or camera system, but it will need a deep dive at the dealership to figure out what element has caused the shutdown of the other.
In any case, this is pretty clearly a warranty job (unless the camera has been damaged by hitting something) but you need to be fair about it and give Hyundai every chance to make it right.
Hyundai actually issued a recall for some Konas with the dual-clutch transmission on precisely this basis. At the time, the reason given was that electrical gremlins within the computer-control of the driveline could cause the transmission to lose drive. Obviously, if you’re merging into fast moving traffic or crossing an uncontrolled intersection at the time, a sudden loss of drive could be very dangerous.
To find out if a particular car was affected and whether or not it’s been fixed, you can quote the VIN to a Hyundai dealer who should be able to give you the good or bad news.
CarsGuide tested the Kona Hybrid late last year (you can check out the review and video here) and came to exactly the same conclusion: That the car was great around the city, but lacked a bit of overtaking oomph at highway speeds.
This will not be a problem for many owners who will possibly never need to overtake on a country road, but for those who do, perhaps there are better choices out there.
Your comparison with the petrol Captiva is a valid one, too. On paper, this car had plenty of urge, but the power was all stacked way up in the higher rev ranges and required some forward planning when overtaking.
Early this year, Hyundai issued a recall for some Konas built between 2020 and 2022 to deal with problems with the eight-speed dual-clutch transmission which could cause a loss of drive and, therefore, a dangerous situation on the road. So the first check would be to see if your car you're looking at is affected by that recall (a Hyundai dealer will be able to tell you by looking up the car's VIN). If the car is one of the affected ones but the recall's fixes have been applied, then you have less to worry about.
The Kona's engine problems, meanwhile, were another cause for a safety recall after it was discovered that a batch of Konas had defective piston rings which could cause early engine wear and possibly even a fire. Again, these problems were being fixed by Hyundai, but you need to check whether the example you're looking at buying was one of the affected ones and what's been done about it by the previous owner.
The Mazda CX-3 of the same era has not been without its recalls either, including one for a suspension joint that could fail, but overall, the experience of owners suggests the Mazda could be the less risky bet. Again, though, check the service and recall history of any car before handing over the money.
The best guess is that the noise is being generated by the electric motor integrated into the steering column that acts as the power-steering in the Kona. If it’s s faint noise that is heard more often with the windows closed and the stereo off, then it’s the same noise that other Kona owners have noted.
Another possibility is a noisy clock-spring. This is a flexible electrical contact inside the top of the steering column that allows the steering wheel to turn while still maintaining all the electrical contacts that power the air-bags and steering wheel-mounted controls. These clock springs often become noisy just before they fail.
Your car is still under warranty, and since you’ve already logged the fault with your Hyundai dealer, it’s now a pre-existing problem and must be fixed by Hyundai, even if the car itself runs out of warranty in the meantime.
It’s pretty simple, James, and despite both two and four-wheel-drive being offered on all trim levels of the Kona, there’s one thing to check that will answer your question: If the vehicle has the two-litre, non-turbocharged engine, it’s a two (front) wheel-drive. If it has the 1.6-litre turbocharged engine, it’s an all-wheel-drive Kona. Hyundai never offered a front-wheel-drive Kona with the turbo engine, nor all-wheel-drive with the non-turbo.
Beyond that, there were some other major technical differences that will also tell you what you’re looking at. The front-drive Kona has a simpler, torsion-beam rear suspension, while the AWD version has a multi-link arrangement. Then there’s the transmission. Front-drive Konas got a six-speed conventional automatic, while the AWD Kona got a dual-clutch seven-speed transmission.
It’s a bit of a surprise to learn that a brand-new muffler lasted just two years before needing replacement, and that’s certainly not what most mechanics would consider normal. But it isn’t unheard of, either.
One of the by-products of burning petrol is water. That explains the cloud-like water-vapour you see when a car is first started on a cold morning. Once the car is up to running temperature, however, that water is turned completely to steam and exits the tailpipe. But, if the vehicle is only ever used for short trips where the exhaust system never gets hot enough to evaporate all that water, then the water can sit inside the system (typically inside the muffler, and in a sometimes acidic environment) where it can cause rust to develop.
This is a lot less common in modern cars with catalytic converters which cause the exhaust to run at a higher temperature and get there faster, but it can still happen – as you now know. The best fix is to fit a stainless-steel exhaust system which simply refuses to rust, but they’re expensive and I wouldn’t expect Hyundai to go to that expense for a warranty claim.
So will it happen again in another two years? If the cause of the rusty muffler is as I’ve explained here, then there’s a very good chance it will happen again thanks to your car’s pattern of use. But if the problem was simply a bad batch of mufflers that weren’t rust-proofed correctly at the factory (and it happens) then a new muffler shouldn’t rot out so quickly. But it makes us wonder if Victoria’s extended COVID lockdown and the notorious five-kilometre-radius-from-home rule may have forced drivers into lots of short trips for months on end. Perhaps you’re seeing the start of a trend here.
Volkswagen’s latest cars are lovely to drive but it’s true; many mechanics (and plenty of owners) are wary of the brand’s recent reputation for reliability. But if you’re buying a brand-new or nearly new example, then the factory warranty will be some peace of mind. The safest bet right now, is something Japanese or South Korean, and that includes the Hyundai you’re looking at as well as the equivalent offerings from Kia. Both these brands have enviable reputations for durability and both come with terrific factory warranties.
Volkswagen’s current high-tech turbocharged engines are very entertaining to drive as well as being frugal in all situations, but, in reality, any current model mid-sized SUV is more than capable of delivering you interstate in comfort and safety as well as offering low running costs. Bear in mind you may have to pay extra for the top-shelf model if you want all the latest safety and convenience technology.
