I have a question about the front stuts. I was changing my oil (12k miles) on my '06 TL, when i noticed my front right strut was quite leaky. The entire upper strut housing of the car had an oil film. When I checked all of the other struts, the left front strut was leaking too. I assume this isn't normal, as i don't remember my other cars leaking like this. How could both front struts fail in a VERY short time, barely 8 months since purchase? Any advice would be appreciated...
