Hyundai IX35 2015 Problems

I’m not sure that this is a common fault, but it’s certainly not unheard of. The stereo in a modern car is like any other electrical appliance; it has the potential to just up and die for no good reason.

But rather than simply replace the unit you have, why not shop around for an improvement. There are many, many, aftermarket stereo systems that will fit your car and will have superior Bluetooth functionality and more features than the stock head unit from 2015. You might find they’re cheaper, too.

I don't think anybody these days considers less than seven years and just over 100,000km to be the lifespan of a modern engine. Certainly not in a car serviced properly. And since this is a known problem with these engines, I think you have a very good case for Hyundai to at least help out with the repairs on a pro-rata basis.

Our experience lately has been that some Hyundai dealerships have been ignoring cases like these and not giving them the consideration they perhaps should be. In any case, any decision to help out with repairs must come from head office, so I'd forget about the dealership for now and go straight to the top. Hyundai Australia has a customer service division and that's who you need to be talking to. Approaching the ACCC should be your last resort, but at least give Hyundai the chance to do the right thing by a loyal customer.

Hyundai’s Theta 2 family of engines does, indeed, have a pretty chequered track record for reliability. But it’s important to note that the majority of vehicles affected have been US-market cars with engines built in a different factory to the cars supplied to Hyundai Australia. For the record, the North American cars in question experienced debris from the engine machining process blocking the oil passages inside the engine, leading to bearing failure. In some cases, the engine failure resulted in a roadside fire.

Even though our iX35s were built in South Korea rather than North America, there’s still a chance the same problem could crop up here given that engineering materials and techniques tend to be standardised across all factories in the name of efficiency.

As you point out, your car is now out of warranty, but I wouldn’t leave it at that. I’d be talking to Hyundai’s customer service department with a view to at least getting some assistance in having the car fixed if, indeed, it was a manufacturing fault that caused the engine failure. I’d also be pointing out that 80,000km is not a realistic life expectancy for a modern engine. To get anywhere with this approach, you’ll need to be able to show that the car has been serviced by the book and (probably) that the failure was due to a loss of oil pressure that led to bearing failure.

Anything can be made to work if you throw enough money at it, but the short answer, Bassel, is no. For the 2014 model year, Hyundai upgraded the petrol engines in the iX35, and the two-litre unit in your car received a direct-injection fuel system. While the basic engine architecture might be the same and the engine would probably physically bolt in, it’s almost certain that the computer in your car would be incapable of controlling the direct fuel-injection function. Your car is also probably missing components such as wiring, a high-pressure fuel pump and sensors required to make the newer engine operate.

You could also run afoul of the authorities because the earlier engine you want to use had a (slightly) higher tailpipe emissions rating. Our regulators take a fairly dim view of a vehicle being modified and going backwards on emissions.

The first thing to do here is to make sure the sensors are clean and free of spider webs, dust or anything else that they might confuse with a parking obstacle. If that doesn’t stop them false-alarming, I’d be letting a Hyundai specialist take a look, as it doesn’t sound like something that can be fixed in the driveway at home. Perhaps you’ll need to replace one or more of the actual sensor units.

But there’s one other possibility that, although it’s a bit of a long shot, might explain what’s going on. Does the problem occur when you’re in traffic and another car ranges up behind at the lights? If so, is the car behind you likely to be one with active cruise-control. If it is, you might find that the radar signal for the other car’s cruise control is actually triggering your parking sensors. I’ve heard of it happening.

It should handle it without any trouble at all. Just remember that the tare weight doesn’t include the things you will carry in the camper, so it will weigh more when you’re towing. Also remember that the towing rating of 1600 kg is for a trailer with brakes, in the case of a trailer without brakes the rating drops to 500 kg.

For beach and basic trail driving I'd be aiming for something with a locking centre differential, which all-wheel drive versions of the previous generation X-Trail certainly had. Another suitable good value option would be an all-wheel drive Hyundai ix35. Both of which were available in diesel. Any common issues will likely be highlighted on our X-Trail and ix35 problems pages.

As I understand it it's not a straight fit. The headlights on your car can be adjusted so have your dealer do it at the next service and see if that improves it for you.

Don't just cop it, that's a cop out. Complain directly to Hyundai and request something be done about it. At the same time go to a car audio specialist and ask them what they could do to improve it.
