I just discovered a dripping leak behind the front driver tire. The liquid is a very light yellow brown and feels watery. I had a major service last week and two front tires replaced. Attached photo of leak color and underside of car where leak is coming from.

Hi,

That appears to be engine coolant. Also, the coolant reservoir is located in that area in the engine compartment.

I attached a pic below showing the reservoir. Open the hood and check to see if that is where the leak is coming from. Also, don't open the reservoir with the engine warm or hot. Wait until it's cool.

Let me know what you find. Also, don't drive it until you confirm the coolant isn't low.

Take care,

Joe
