Dashboard and fog lights in 2012 Hyundai ix35 not working
Answered by David Morley · 28 May 2024

If you’re lucky, the problem might be as simple as a blown fuse that controls these circuits. So that’s where to start checking. The instrument panel lights and rear fog lights in the Hyundai are on separate circuits, so you’ll need to locate both fuses. Start with the internal fuse box located low down on the dashboard near the steering column. The inside of the cover will have a map of which fuse does what, but don’t forget there’s also a second fuse box under the bonnet.

If the problem is not a blown fuse, or the fuse blows again once you’ve changed it, you’ll probably need to services of an auto electrician to figure out where the power is going and what’s the cause. A poor earth somewhere on the car or a short circuit are two likely culprits.

Intermittent system faults in Hyundai iX35?
Answered by David Morley · 03 Oct 2025

A poor earth is often the cause of this sort of misbehaviour and it’s a good place to start looking. Check the earthing points in the engine bay and around the area where the tail-lights are earthed in the cargo area.

You might need to lift some carpet or trim pieces, but when you find the earth points, make sure they’re tight and clean and not covered in corrosion. Don’t forget to check the tightness and cleanliness of the battery terminals, too.

Beyond that, these symptoms point to a problem with the car’s body computer which controls all these functions and many more.

When this computer starts to die, all sorts of weird and random flaws can occur. But try this first: Disconnect the battery of the car and let it sit overnight. Reconnect it next morning and keep a close eye on what happens. Sometimes this simple trick will reboot the body computer and normal service will be resumed. Best of all it’s free.

Increasing oil level in a 2012 Hyundai ix35
Answered by David Morley · 23 Feb 2024

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.

Hyundai ix35 2012: Can a peeling steering wheel be fixed?
Answered by Graham Smith · 12 Jan 2018

By all means you can try, but I doubt that you will have any success. The car is six years old, and the steering wheel is something that is subject to wear simply from being handled.

2012 Hyundai IX35 is blowing smoke
Answered by David Morley · 26 Jul 2024

When an engine blows thick white (or bluish-white) smoke, it’s often a sign of internal engine wear. Some Hyundai engines have had problems with major engine components developing premature wear and causing similar problems to the ones you’ve experienced. But some Hyundai engines of this era also suffered problems with the EGR valve (exhaust gas regulation, part of the emissions control system) and that could lead to similar problems.

The best advice is to have the vehicle inspected for internal wear or any other problems that could be causing the smoking under load situation. This is pretty back to basics stuff and would include a compression test and leak-down test and should be well within the capabilities of any decent workshop. From there, you can make a more informed decision on whether to spend the money to have the car fixed, or cut your losses and move on.

It's also worth mentioning that Hyundai has been very pro-active in helping out owners who have experienced premature engine-wear problems, but the age of your car plays against this. It would be worth contacting Hyundai’s customer service division, however.

My 2012 Hyundai ix35 won't start
Answered by David Morley · 07 Aug 2026

What you need to do is work backwards and check every connection and wiring plug that is anywhere near where you were working. A single unplugged (or even loose) sensor, connection or fitting can absolutely sideline a modern, electronically controlled engine.

You may also find you’ve damaged a sensor in the process of cleaning it (they’re pretty sensitive things) so a scan of the car may reveal that.

Also, was the cleaning process initiated by an existing problem that made you think the sensors needed cleaning? Cleaning an already dud sensor rarely brings it back to life.

My information suggests the crank-angle sensor for this engine is located on the rear of the cylinder block (near where the engine joins the transmission) near the oil filter housing. It’s usually hidden by a small heat shield and requires that and a 10mm bolt to be removed to remove the sensor.

Access to the wiring harness is usually from above, but the sensor itself is most easily removed from underneath the car after removing any relevant plastic shielding.

Used Hyundai iX35 review: 2010-2015
By David Morley · 14 Sep 2026
We’re not sure exactly what was going on in Hyundai’s marketing department at the end of the first decade of this century, but somebody was definitely having two bob each way. Up until 2010, the Tucson had been Hyundai’s mid-sized SUV entrant, but that badge disappeared the same year as the ix35 hit showrooms as the Tucson’s replacement. But after just five years on sale, the ix35 was itself replaced by none other than the Tucson. Confused? Us too, but to keep it simple, if you’re shopping for a Hyundai-made mid-sized SUV built between 2010 and 2015, the ix35 is the badge you need to look for. Meantime, leaving nomenclature out of it, the LM (as it was known internally) ix35 was a bread-and-butter kind of family SUV with familiar overall proportions and nothing too confronting mechanically. It could be had in three trim levels (Active, Elite and Highlander, in that order) and with a range of driveline options. There was a 2.0-litre petrol engine with 122kW, a 2.4-litre petrol with 130kW and a 2.0-litre turbo-diesel with 135kW and lots more torque than the petrol variants. The 2.0 petrol was available with either a five-speed manual or six-speed automatic transmission and was front-drive only. The 2.4 petrol and the turbo-diesel were fitted exclusively with the six-speed automatic and were all-wheel drive, although they used on-demand AWD, and operated as front-drivers in most conditions. Conventional wisdom says late-model Hyundais are pretty stout things, even if they don’t offer much in the way of driving excitement. The ix35 makes sense if all you want is a roomy (for its size) box with which to move people and their belongings. But even then, there are some reliability problems to note, and driveability was never anything better than average. Overall, there are better, more entertaining choices in a second-hand SUV of this type. Again, it goes against the mood for this brand, but the ix35 did have some serious reliability issues that, even though they didn’t affect every example, should make you weigh things up carefully before making a purchasing decision. Something very wrong was going on in Hyundai’s engine department at this point in history. All three of the ix35’s engines suffered (to some extent) with some serious issues that saw Hyundai replacing entire engines under warranty in an attempt to stay in favour with its customers. The problems mainly centred around engines that consumed excess oil (to the point where some owners were caught out with empty sumps between services) and rattling engines that were signalling their death knock. The consensus is these problems were caused by poor manufacturing accuracy, leading to cylinder scoring, at which point the engines became noisy (particularly when cold) and started to burn oil. The fix was to either rebuild the engine with a new crankcase or, more commonly, replace the whole engine. Other issues reported over the years have been interior trim peeling (most notably steering wheel covers) and flaking paint caused by a bad batch of paint that affected other carmakers (including Toyota) and was traced to the top coat not adhering properly to the undercoat at the factory. This model Hyundai has had its share of recall notices over the years, some of them more serious than others, but a couple posing a definite safety risk. They include a recall to check the seat belt tensioning system, and a driver’s airbag that could have been assembled incorrectly and not deploy as it was designed to. Leaks were another ix35 recall theme, with oil leaks from the sump, fuel leaks and transmission fluid leaks all creating recall notices. There was also a recall to check some cars for a brake system that could allow brake fluid to contaminate the ABS module, leading to braking problems. You can check out the full details including what batches of cars were affected at: https://www.vehiclerecalls.gov.au/ If you’re buying a petrol ix35, the ones to avoid on the basis of the engine problems and oil burning were the ones from the first generation built between 2010 and 2013. If, however, you’re after a diesel version, the post-facelift cars (2013 to 2015) seem to be the problematic ones. Either way, you’d want to know the service history of any second-hand ix35 and be prepared to shell out for a pre-purchase inspection which would include a compression test and perhaps even a bore-scope examination of the engine. The number of ix35s still floating around with 250,000km on board, or even more, suggests the engine problems were a bit random and clearly didn’t affect every car. We’d still be a lot happier, though, with an example with less than 160,000km on its odometer, along with an up-to-date and complete service history as some proof of it having a chance at going the distance. A car with a factory replacement engine (and documentation to support this) would also be preferable to one with no history. The turbo-diesel ix35 was always the better one to actually drive thanks to its beefier power and torque delivery. The added safety of all-wheel drive only reinforces this view. The petrol versions do the job, but they can feel breathless and stretched a bit tight at freeway speeds when fully loaded. Right now, you’ll find sellers with early-built, high-mileage examples of the ix35 with an asking price of about $5000 or even less. But these are best left to speculators. Better value is to be found in the $8000 to $10,000 price range where you start to find diesel examples with much more moderate mileage showing. Don’t forget that service history. Hyundai is a big brand not just in Australia, but globally. So, spare parts are not hard to find. Neither is a workshop that can navigate what is, fundamentally, a pretty straightforward vehicle. There’s a huge online market for parts to suit cars like this one, but be wary of online sellers you haven’t used before. Don’t rule out parts recycling yards for spares like body panels and some mechanical parts. Despite the problems some owners experienced with this car, Hyundai managed to sell plenty of them here, with sales peaking at about 18,000 per year at one point. That gave it a huge chunk of the market in its segment, but those mechanical problems took their toll, leading to the badge being replaced by the revived Tucson model in 2015. Some owners were forced to walk away from their ix35s when the cost of repairs became more than the value of the car itself. But the sheer sales figures when things were looking good mean there are at least a couple of hundred ix35s for sale on the bigger online sites.
