Hyundai ix35 Engine Problems

Does the Hyundai iX35 engine have any issues?

Answered by CarsGuide 24 Nov 2021

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.

What engine replacement will work in my 2015 Hyundai iX35?

Answered by CarsGuide 20 Jun 2020

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.

Hyundai ix35 2013: Why is it loosing acceleration?

Answered by CarsGuide 6 Jul 2018

Intermittent problems like yours are always hard to diagnose and fix because they rarely occur when the mechanic is present to observe them. It seems as though yours has gone into limp home mode after the computer detected a fault. The only course of action is persistence until the source of the problem shows up in a diagnostic check, or when the mechanic is there to witness it.

Hyundai ix35 2010: Not starting

Answered by CarsGuide 15 May 2017

All non-commercial used cars sold in New South Wales are by law meant to have a warranty of 3 months/5000 km if they are less than 10 years old and have done less than 160,000 km. But even if it met those criteria you have had the car for six months and the warranty would have expired.

Hyundai ix35 2014: Sudden deceleration fixed

Answered by CarsGuide 23 Jan 2015

No, we haven't had any more reports of this issue, but it sounds serious. Hyundai has fixed your car before, so I would return it as you are doing and press on them the danger of the situation you found yourself in when it happened. Lemon laws where you could get a replacement car don't exist in Australia, and the consumer laws we do have are pathetic and few people have the fortitude it takes to pursue it to the end.

CX-5 or Qashqai to replace ix35?

Answered by CarsGuide 17 Nov 2014

The 2.5-litre petrol engine in the CX-5 will give you the zip you want. If you need oomph for towing, go for the diesel.

Answered by CarsGuide 15 Aug 2014

 You have no chance of getting a replacement car and there is no reason to think that your car will not be fixed when the repairs are done.
