2024 Hyundai Ioniq 5 Pricing and Specs

Glad to hear you've had such a great run with your car. I understand what a great safety device a reverse camera is, and if it was standard fitment in your car when it was new, it could very well be a roadworthy item if it's not working. However, I wouldn't be too worried as the GPS and bluetooth functions should not be related to the reverse camera or the cruise-control.

If the reverse camera screen ever went on the blink, you could fairly cheaply add a replacement aftermarket unit which would also restore your Bluetooth and possibly even your GPS functions.

Hyundai has had a few problems over the years with some of its engines developing piston slap, scoring cylinder bores and consuming excess oil. The later engine fitted to your car should be better, but it seems perhaps the problem is still occurring in some cars.

The reality is that two litres of engine consumed over just 1200km is way beyond the pale. I would be contacting Hyundai Australia's customer service division to see what can be done. The company's response will have a lot to do with how many kilometres the car has covered and whether its service history is complete. But in my experience, Hyundai takes its responsibilities in this area very seriously.

This was a huge problem for manufacturers back when turbo-diesels first started using Diesel Particulate Filters (DPF). The problems started when owners were using their diesel-powered vehicles just as they had their previous petrol cars. That is, for short, urban journeys where the exhaust system never got hot enough to perform a DPF regeneration (which is critical to the way these filters reduce tailpipe emissions).

To counter that, some manufacturers programmed the engine to dump extra fuel into the exhaust to get it hot enough for a DPF regeneration. Inevitably, however, sometimes some of that extra fuel found its way past the piston rings and into the engine's sump. And suddenly, there was more oil in the sump one day than had been there the previous day.

The problem there was that the diesel now in the sump was actually diluting the engine's lubricating oil, and that could lead to accelerated engine wear and bearing failure. The best solution – then and now – is to make sure you drive the vehicle at freeway speeds for at least an hour every three or four weeks. That will get things hot enough for the DPF to regenerate if it has to, and not rely on the extra diesel the computer will pour into the engine.

You could be looking at a specific DPF problem or maybe a software glitch that is messing up the regeneration, but if the level on the dipstick is rising, then I'd say that's your problem.
