Hmmmm.....let's just look at the Acadia Forum then. 68 reported leaks on the forum / 5166 forum members = 1.32% of forum members reporting a leak. 68 reported leaks / 116,431 (All Acadias sold) = 0.0584% of all Acadias sold. I fail to see how that is being "intellectually dishonest" when the original poster of this forum REFERENCED the forums and the "supposed" CONSTANT reporting of leaks on said forums as causing them concern. The only "hard numbers" at our disposal are the above numbers from the forums and the only evidence I had to go on. How is taking actual mathematically supported statistical data from said forums being "intellectually dishonest"?
I truly am sorry for those that have had a leaking problem and am not trying to minimize it. HOWEVER, as someone else posted here.....EVERY model of every car built with a sunroof, moonroof, etc.....is going to have SOME bad apples that will have leaks. It is only the law of averages. I simply do not believe that there is a higher risk of leaks on a lambda with sunroofs than on any other vehicle with sunroofs.
Clearly you didn't even read my post. Your logic is just plain flawed because it makes invalid assumptions, which I won't bother to repeat since you didn't read them the last time. Here's the real math:
116 voters with sunroofs on the Acadia forum.
63 leakers (54%!)
Do I think that 54% of Lambda sunroofs actually leak? Of course not. I understand it's an unscientific poll. But I sure as heck don't believe that only .0584% leak either. Why would you even express it as a percentage of all Lambdas sold anyway? This issue is on Lambdas with sunroofs. And if there is not a higher risk of leaks with Lambdas, why did they have to issue a recent TSB about it that lists a litany of reasons why they leak?

Condition

The stationary glass roof drains may allow too much water for the drain system and thus overflows onto the headliner and into the vehicle.
Heat from the roof may cause the right or left middle sunroof drain tubes to shrink and come off at its attaching point on the module.
A drain hose may not be fully seated.
A drain hose may be improperly routed.
There may be a void in the sealer under the roof ditch molding.
The end of one of the front drains may be plugged with grease from the sunroof or debris may be caught in the cross hatch at the end of the drain tubes.
