I have been having problems with the car transmission slipping since Jan 2014. On Jun 25, 2014 I was driving on the expressway and I heard something pop thinking it was the transmission. After this happened I pressed the gas pedal to the floor and the car would not speed up but the rpms were high. I took it to the dealership the next day (5th visit) and they had to sent a tech out. I have attached his findings. Once the tech did his inspection the manufacter has said they won't fix the car because my warranty is null in void due to me being unable to produce oil change receipts. My questions are 1. Is the turbo in this vehicle cooled by oil or by air? 2. Is it possible that due to "lack of lubrication" caused by "poor maintance" can cause the retainer nut to be inside the turbo housing, if so what are the chances of this happening? 3. Wouldnt more lubrication cause the but to become looser? 4. Can you explain the two codes on the invoice?

Where the arrow in the pic is is where it is lubricated from engine it goes with pressure back to oil pan after lubrication. I'd think I'd call kia and complain not the dealer they may do more for you. Asking for receipts is kind of a cop out on their part and kia may send you to another dealer. The retainer nut is on the outside where the fins are to give the car boost the turbo spins very fast so it doesn't use lubrication there only where the arrow is. The only way the retainer nut cold come loose from oil is if the seal in turbo went out. These engines should use synthetic oil by the way due to heat. There is a tsb-service bulletin to not use aftermarket oil filters as well as the correct oil viscosity this may be what they are making their judgment on. If they still refuse to do anything then your cheaper option would be to a garage and getting a used turbo put on.

Thank you for the reply. So can not doing a oil change according to their schedule cause the turbo to be seized due to poor lubrication? I have complained to corporate KIA many of times in writing as well and they haven't been very helpful neither has the dealership? They said they are signs of sludge build up that plugged up the inlet oil ports to the ocv and cvvt. So does this mean that the engine needs work or just the turbo? Because the quotes that they have given me on if the engine and turbo have to be replaced is half of what this car is worth. Corporate kia is the ones that have told me the warranty is null in void. Thank you once again.
