new 2018 nissan maxima for sale in kent kirkland washingtonHi Robert,

My friend was driving behind me recently and said she saw some fluid come out my 2018 Nissan Maxima's exhaust. I’m just wondering what this is and if I should be worried.

Thanks,
Amanda

Hi, Amanda!

This may or may not be a problem for your 2018 Nissan Maxima depending on what fluid is coming out of your exhaust.

More often than not, when you see fluid coming out of a vehicle’s pipe, it’s water. This is caused by condensation which has formed inside the exhaust system and is usually accompanied by thin white smoke: this is nothing to worry about.

If your car has been warmed up and running for a while but thick white smoke and water are coming out of the exhaust, it could be a more serious issue; this may indicate that you have a blown head gasket or a cracked engine block.

The fluid coming out of your exhaust could be gasoline, and this would indicate that there’s an incomplete burn in the combustion chamber. Essentially, the fuel/air mixture is not igniting properly and the excess is coming out of your pipe.

If you're experiencing the second or third issue listed above, you should call into our Service Department and let the Technicians have a look.

Thanks for your question, Amanda! Contact Kirkland Nissan, Washington again if you need anything else.
