Kia Carnival Diesel Problems

There are two things you need to do. The first is to have the vehicle independently inspected. The RACV is very good for this as it has the resources and a reputation that the car industry respects. Once you've found out what really went wrong (as opposed to what the dealership may have told you on the spot) you can proceed. This will inform what happens next.

If the engine failure was not the cause of a poorly fitted oil filter and was something to do with a manufacturing or materials flaw, then you have a case for a warranty claim. Bypass Kia's dealer network and contact the brand's customer service division at head office.

If, however, the failure was caused by a lack of attention by the mechanic who carried out the last service, then the responsibility may rest with them. Mechanical workshops often have insurance to cover them against this sort of mistake but, regardless, if your mechanic was at fault, the problem becomes theirs in many cases.

A modern vehicle like the Kia has a range of engine protection and warning systems to prevent this sort of thing happening. It seems strange that you didn't receive a dashboard warning regarding low oil level or low oil pressure in the moments before the engine failed.
