Had two error codes P3400 P3497 and NO oil light. Internet said to check the oil and we did. There was basically NO oil in the car and the oil light NEVER came on. What the heck!!! I found out there was a class action lawsuit about this and I never knew anything about this. How come I never knew about this? I have had to have my spark plug changed twice in two years and it turns out that these codes are the reason. This error code should be a recall.
