Hi,Hey , thanks for the reply .
I'm in Victoria .
Yeah the service centre is pretty useless if you have a problem that is anything above simple , the communication is just not there as you don't speak directly with the person working on your car ( in my case, although i think this is common ) .
Possibly the only answer to this problem we have is to take it up with someone at Hyundai Australia or at least hint that to the service centre you go to as they seem pretty scared if Hyundai sends out a survey and you rate your experience less than 10 .
I don't know what the software update is called as it was not listed on my receipt .
My next service is probably going to be later this year so i'll just try get used to it for now , but my brother claims to know someone who works high up in Hyundai so i might try exploring that option soon , i'll let you know if i get anywhere .
I'm in Victoria as well
I took my car to Nanuwading Hyundai for a noisy diff then that didn't resolve anything and ended up with some update and since then my car is having this intermitted issue. Went back and forth with them and they have failed to acknowledge or rectify the problem as I have insist that is was the update that made the car running funny and they kept denying it. I took it up further with Hyundai Australia spoke to this gentleman named Sam he was helpful at the start and escalated the case but then nothing happened soon after communication went quiet and no longer returning my calls or emails. I took it to 2 other dealers which was in Ferntree gully and Lilydale Hyundai and they both could not fix the issue and kept denying it cant be an ecu update. So i have tried everything and gave up on it as it was stressing me out. Now few months has passed I'm willing to fight and finding answers again and I hope you would shed some light with your experience maybe we could even meet up and test drive each others car to see if it's the same issue only if you have time no stress. Keep in touch and good luck mate.
