2018 Sonata oil issues
I’ve had previous posts regarding the oil consumption issues with my car. I am the only owner and bought it new from this dealership. In the last 2 years it has failed I believe 3 oil consumption tests and has had 4 combustion chamber cleanings. (Corporate and the dealer all refuse to replace the engine even tho it’s a known issue with this particular one) I come in for an oil change today, and they tell me that it looks like the oil is mixing with the coolant. And seems to be leaking some oil from the drain plug. Could be head gasket issue. Could be leaking from the oil pan etc etc. I am paying $217 for the diagnostic to figure out what’s happening. I initially asked them to let me know how much oil it has used since the last oil change. I know that the oil was barely registering on the tip of the dipstick this morning. I have also put 2 quarts in myself.
Is it possible that all of the combustion chamber cleanings in a short amount of time could cause other issues? Again, it’s just now at the dealership and I won’t know until later what the diagnosis is.
Any advice at this point is greatly appreciated.
