What owners report

• “The cooling system failed without warning! As I’m driving on the highway my vehicle began smoking! I smelled a burnt smell!

I check my vehicle every morning before work as I drive through three counties to get to work and my coolant was full as I had just topped it off that morning! Upon inspection it was found from a local mechanic to be the water pump! My truck was fine last month upon getting a n inspection.”

Fuel was coming out and created a significant fire risk to life and property. Audi has refused to deal with the issue and speaking with mechanics at 3 dealerships revealed that the replacement parts are failing at an alarming rate. I would like this looked into.”

Excessive oil consumption occurs because the combustion chamber is not properly sealed off from the Audi turbo engine parts that need to remain lubricated.

As a result, our 2015 Audi Q5is at risk for immediate loss of engine power. There is currently a class action law suit…”
