Kia Sportage Problems

You’ve paid for a car with a factory warranty, so make the most of it. The first step is to have Kia look at the car, listen to the noise it’s making and come up with a plan from there. Convincing the dealership mechanic that there’s a noise that shouldn’t be there might be difficult, but you could also have the car independently inspected (try your state motoring club) the noise noted in writing, and present that to Kia as a way of proving there’s a problem.

In our experience, Kia has been pretty good at getting this stuff right and keeping its customers happy. So start with the dealership and if that doesn’t work, you can contact Kia’s Australian customer service department. After that, it’s a job for the ACCC, but it shouldn’t come to that.

The bottom line, however, is that this car is (or should be) still under factory warranty, so it’s Kia’s problem to sort out; a process that should not cost you anything.

It sounds like there’s either a problem with the throttle pedal, the throttle mechanism itself or, most likely, a glitch in the communication between the two. Instead of a throttle cable directly linking the pedal to the throttle, modern cars use what’s called fly-by-wire. In this case, that means a throttle pedal where input is converted to an electrical signal, which is then transferred by the computer to the throttle telling it to open. If there’s any wiring or software problem within this system, you could easily experience this sort of problem.

You’re quite right, too, that this represents a very dangerous situation. Many crashes have been caused by a following driver assuming the car in front was about to take off. And when, for whatever reason, it doesn’t…

If the computer won’t tell you what’s happening, an auto electrician should be able to take readings from the throttle pedal and the motor that actuates the throttle itself. From there, they should be able to discern which component is not playing the game properly.

For a lot of second-hand car buyers, the opportunity to purchase a car with a year of factory warranty remaining is a big deal. It’s great peace of mind and that means a lot to some people who are sometimes a bit spooked by the level of technology in modern cars. On the basis that you’ll be selling the car in the next 12 months or so, perhaps now is the time while that warranty is still there to attract would-be buyers.

However, you must be able to prove to a buyer that the car has been serviced correctly and at the appropriate intervals. A car without a full, correct service history is, effectively, a car without a warranty regardless of how old it is. Make sure the service handbook is fully stamped and in the glove-box. By the way, your car’s warranty started when you bought it in late 2018, not 2019 even though it’s a 2019 model-year vehicle.

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.

There could be something wrong with the vehicle that is causing engines to blow up, and simply fitting a new engine is leaving it open to the same catastrophic problem(s). A fuel supply or cooling system problem would be just a couple of possibilities and fitting a new engine to a vehicle with such a problem could easily lead to successive blow-ups.

There’s also the possibility that you’ve simply been unlucky. Was the second engine a used one from a wrecking yard or a rebuilt unit? If it was the former, you might find that it was just about ready to expire, and the fact that it was fitted to your vehicle was not a factor. This is why it’s always important to have any second-hand engine tested before it gets fitted. Good quality used engines will come with a written report to prove there’s some life left in them.

There’s also the owner’s approach to a new engine. Were you careful to check the oil and coolant of the new engine once it was fitted and running? A second-hand engine might have an oil consumption pattern you’re not familiar with, and ignoring this important check could see it run dry and expire. Not pointing fingers, but even a 'new' second-hand engine requires a close eye kept on it.

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.

You could be looking at an engine that has a fuel-system problem. A lack of fuel pressure or volume (or worn injectors) can play havoc with a turbo-diesel engine at higher speeds thanks to the higher loads being placed on it. You may also have a worn or damaged turbocharger or perhaps an inlet manifold that is partially blocked from fumes and soot that are part of the vehicle’s emissions system. The problem could even be due to a blocked DPF in the exhaust system which could require manual cleaning or even replacement.

But this is another example of a car that’s still under warranty being the responsibility of the manufacturer to put right (provided the vehicle has been serviced correctly). Give the dealer very chance to fix things, but if they throw their hands in the air, then Kia Australia’s customer service department is your next stop.

It doesn’t sound right, does it. And why would Kia even include a low-beam light indicator if it wasn’t to show that the low-beam lights were, in fact, on?

You should be able to figure it out by looking at the owner’s manual for your car. I managed to find such a thing online for your model Sportage, and it shows only a high-beam indicator light and a lights-on warning which covers both parking lights and low-beam. That suggests that your dealer is correct.

The other question, however, is what you’re looking at that makes you think it’s a low-beam warning light. The answer could be that there are two high-beam indicator lights, one for the manual high-beam operation and another for the automatic high-beam if your vehicle has that fitted. Perhaps it’s the fog-light indicator you’re seeing. Again, your owner’s manual should spell it out for you.

It doesn’t matter whether you have the two-litre petrol, 2.4-litre petrol or the two-litre turbo-diesel engine in your Sportage, they all use timing chain technology rather than the toothed rubber timing belt. As such, the timing chain fitted should be good for the life of the engine and should not require periodic replacement as a timing belt does.
