I have encountered this problem primarily at low speed maneuvering through parking lots. There is absolutely no power boost while the serpentine belt slips due to the moisture. Loss of steering is an extremely dangerous condition even at low speeds. I have reported this to the NHTSA. If enough complaints are registered perhaps a safety recall might be issued to address this problem. It is easy to do this using the NHTSA online form at this URL.

Way old thread, please start you own new in things like this. The splash pans on a GXP make it pretty hard to get the belt wet. The bottom of the engine bay is completely covered. Next to impossible unless your driving through a pond sized puddle. I have never seen mine such. I'm of the mind the sensation is in fact the StabilTrack dampening the steering hard. The power loss is timing being pulled by the same sytem. Something it can do quite strongly in wet or icy conditions. As far as the NHSTA, pffft. the car'* to old and it'* too late. Typically they won't raise an eyebrow till something either burst into flames or people Die.

Perhaps a component was left off my vehicle during it'* build.

Looking directly down at the serpentine belt area on my car there is a substantial opening adjacent to the wheel through which moisture can be deflected onto the serpentine belt causing it to slip for as much as 30 seconds. I have numerous instances of this happening and it has nothing to do with the StabilTrack system. Loss of power steering is complete until the belt sheds the moisture and begins to drive the power steering pump, AC etc.

If your vehicle, in fact, has a cover in this area of the engine compartment please let me know. I would certainly like to find one to put on my car to eliminate this unsettling condition.

Moved this to it'* own thread.


There should be a shield there, it'* possible that at some point in the past a shop left this shield off after doing some work. I have 2 sites you can look at for the part. First is www.rockauto.com The other is http://www.trademotion.com/partlocat...&siteid=214638 You can also try calling local salvage yards.

Can somebody post a pic of the part that is supposed to be there? Mine must be missing because any good-sized puddle will squeal the belt and lose PS.

I have checked several online parts suppliers and so far have found no pictorial showing this part. I suspect a visit to my nearest GM dealer'* parts department is in order. This appears to be a pretty obscure part. Perhaps if someone does in fact post a photo of this mystery part they might also discover a part number stamped into the assembly.

If you have a pick and pull salvage yard in your area I would suggest a trip there.

i can snap pics
are we talking on the passenger side? can you post a picture so i can match with mine or atleast know where it is lol

"are we talking on the passenger side?"

Well, yes.

Everyone appears to indicate their GXPs have a splash shield in this location. There is nothing in this area on my vehicle.It is open directly through to the pavement as you can see in this photo.

My car has the same symptom when hitting a puddle. And it doesn't have to be a lake sized one either. I have to check for this shield, but no one has worked on my car that hasn't replaced everything.
