My wife has a 2013 Nissan Quest with 60,000 miles on it which yesterday started smoking on startup and the check engine light came on. It is overdue on the oil change by 9k and when I checked the dip stick it is caked with sludgy oil. When it starts it puts out a cloud of blue smoke for about 15-20 seconds and then stops. I only drove it the distance from the house to the dealer (about 15 mi) and it ran fine both in town and on the highway. No smoke, no hesitation, normal amount of power, no strange noises.
The dealer ran the code and came up with errors on both valve solenoids (its a V6). They said its been driven too far without an oil change and would diagnose it no further. The only option, according to them is to replace the motor. Also, they changed the oil and said it continued to smoke.
So, obviously it was let go WAY too long between oil changes but there was no low pressure light, no over heating, no other indicators of an issue. Also, 14k between changes while not ideal by any stretch should not destroy the motor…
I am picking it up from the dealer tomorrow and don’t really know where to go from there with it.
