Hyundai I40 Problems

The answer is no, but Hyundai's naming policy was very confusing during the 2010s.

The original i30 of 2007 introduced the alphanumerical naming policy and signified a different approach to vehicle engineering, with a European focus with higher-quality engineering rather than a low price to take on class leaders like on the Volkswagen Golf.

Thus 'i' something became a sort of premium nomenclature, and of course is still used to denote this on models like the i30 and Europe's i10 and i20 small cars There was also the German-engineered i40 midsized sedan and wagon until 2018.

But here's where Hyundai muddied its own waters.

In 2010 the larger, American-market Sonata was rebadged i45 for Australia and New Zealand – even though an 'x' and a '5' rather than a '0' meant crossover or SUV, as illustrated by the very popular second-generation Tucson being renamed ix35 in Australia and some other markets from 2009 to 2015 – though this naming policy was abandoned for the third-generation Tucson from 2015. While strikingly styled, there was nothing European about the i45, and it too returned to being badged Sonata from 2015.

So... i10, 120, i30, i40 and i45 for Australia, but no i35.

Thank you.

The Hyundai i40 has a great reputation in the trade for being a solid, dependable car with few inherent problems. In fact, it’s one of the models that has recently helped forge Hyundai’s overall reputation as a safe bet. The brand’s five-year warranty hasn’t hurt it in that regard, either.

In terms of Hyundai i40 diesel engine problems, the news is good. And that’s largely because Hyundai has been building small capacity passenger-car diesel engines for decades and has the technology all worked out.

But there are a few things to watch out for and those include the propensity of modern, common-rail injected diesels to require plenty of preventative maintenance. If injectors, pumps and filters are not looked after, they can all give trouble down the road and fixing common-rail injection is generally not a cheap pursuit. So make sure any second-hand i40 (petrol or diesel) has a fully stamped service book and that no preventative maintenance has been skipped.

The other thing worth mentioning is that unless you plan to do at least some highway driving, then the turbo-diesel – as nice as it is to drive – may not be your best bet. The Diesel Particulate Filter (DPF) fitted to modern diesels needs a good run at a decent speed every few weeks to ensure that it can regenerate properly. If it doesn’t see this sort of running, it can become blocked and, in a worst-case scenario, require replacement. This is by no means a Hyundai-specific problem and many modern diesels with DPF technology carry the same caveat.

The bottom line is that even though the diesel version of the i40 may squeeze more out of each litre of fuel, it’s not necessarily the cheapest-to-own variant in the long run.

You’re buying a used car, it’s not new, so you have to expect some wear-and-tear issues. The older the car, the greater the wear-and-tear, and the more likely it is to have suffered mechanical failures or even a crash. That means you have to thoroughly check the car before purchase, and you have to rely on the honesty of the vendor. If the car has had clutch problems it should be recorded in the service book. It’s the same with the others you’re looking at, check them thoroughly, and if you’re uncertain have an expert check them for you. Of the three others you are considering I would avoid the Passat as a potential money pit, and go for the i40 in preference to the Commodore.

That’s the problem with VWs, you can get six good ones in a row, but the next one could be a lemon. Rather than a wagon you’re probably looking at an SUV. I would suggest a Kia Sorento, Subaru Outback, or Toyota RAV4.

As I am sure you have been told clutches are considered wear and tear items and as such are not covered by the warranty. If it's found the cause is something other than a worn clutch rectification would possibly be covered by the warranty, but if it's shown to be a worn clutch you will be up for the cost of repairs, which will include the cost of tearing it down. I don't see there's any escaping that cost.

The i40 is a good choice; it ticks most of the boxes. It’s well equipped, well built, reliable and durable. You could also look at wagons like the VW Passat, Ford Mondeo and Mazda 6, but it’s hard to go past the i40.

Normally the glass isn’t covered by the warranty; it comes under the wear-and-tear category and so is excluded. But a shattered rear glass would appear to be different to the regular run of glass failures. I would first attempt to negotiate with Hyundai and mount a case for compensation that they couldn’t possibly refuse. You could go to the Ombudsman, but that will take time and I would doubt if it would ultimately help.

You will definitely find it easier to work with the Hyundai at your height, and it's a very practical wagon as well. I'm not a fan of the Outlander, which makes it easy to recommend the i40.
