I had my '06 TL for about 2 months now and I've noticed the brake pedal had gotten soft. It catches much further down than the day I drove off from the dealership. I brought it back once and they couldn't find the problem, so they flush the brake fluid and it was fixed. However, the problem has started again, this time I've used a ruler to measure how far the brake pedal was when it actually felt firm. I suspect a slow leak somewhere in the brake system which allow air to get in, but not really sure. Can anyone help? Thanks.

Mine had the same problem. I had to bleed the brake to get the air out. My thought is that the brakes are boiling the fluid and causing the air in the lines. I am thinking about switching to a high performance brake fluid soon. Mine has been better than it was was by far but I may need to bleed them again. I hate dealerships so I try to avoid them at all costs.
