One problem related to coolant leaking has been reported for the 2015 Jeep Renegade. The most recently reported issues are listed below.
Jeep is burning oil and coolant between oil changes. Need to add oil at least every 2 to 3 week and coolant monthly. No warning lights have ever come on indication the vehicle is low, it has not over heated. Have found Jeep to be upto 3 quarts low on oil and no coolant in reservoir. No signs of leaking of any kind. Have noticed a distinct smell of burnt oil after long drives. When adding oil and coolant today I found a pink frothy residue on all the house joints for the coolant. Why am I not getting any warning lights and where are these fluids going to. There is distinct metal sound when the engine is running now. I addressed the oil issue with the deal the last time it was in and I was told I just need to add oil periodically that "all vehicles" periodically need oil. I have never had this issue with any other vehicle I owned.
