My 2017 Hyundai i30 is losing a lot of oil between services

Asked by Erin

My 2017 Hyundai i30 is losing a lot of oil between services and has no leaks. The check engine light has appeared on my dashboard. I had the RAA out who said they thought it was a faulty crank sensor when scanned. I took it to my normal mechanic who took it apart and said it looked like the loss of oil had stretched the timing chain. They said I need to go back to Hyundai to get them to assess it as there is a class action against these engines.

Hyundai wants to charge me between $200-1200 for something I already know is wrong. This seems very unfair as I have had my car serviced regularly. I understand they need to look, but really? Then, they might turn around and say they won’t help with the cost. What should I do?

I’ll assume it’s a Hyundai dealership that wants to charge you to assess the car. And I hear what you’re saying about the car’s service history and the fact that some of these engines have been fixed by Hyundai because they were faulty from new. So, the best advice is to forget about the dealership and go straight to Hyundai’s customer service department at head office.

That cuts out the middle man at the dealership and should get you in touch with somebody who knows whether your car was one of the affected ones or whether you’ve just been unlucky in this instance. My experience has been that Hyundai takes this stuff very seriously and has helped other owners in the past. However, your case will still be assessed according to the service history and how many kilometres the car has covered.
