Pinch welds, Pinch welds anyone?

I purchased a 2019 Chevy Malibu last week, despite it's cosmetic defects (previous owner had 5 kids who scratched the heck out of the paint - but not too deep) the car runs and drives fine. As far the as the naysayers I ran across saying the trans was jerky and garbage, thats because you're not supposed to punch the gas while the start/stop is active.

I am however curious where in the world the pinch welds are on these cars. I think I can see them but they seem a bit thin compared to my Buick and Honda.

Don't want it to be obvious to the dealership that I've been jacking the car up and crushing the welds.

Would it hurt to ask folks to post pics if you got em?

Thanks in advance.

No.idea why you're angry at me? I've only spoken the truth. Never said I agree with it.

BUT no one should brings cars to a dealer after warranty aside from recalls or as an utter last option.

It has a CPO warranty from GM but brakes aren't on he list of things that it covers, so I still have 30k more miles of warranty
 
Page 308 of the owner's manual says

"Position the jack lift head at the jack location nearest the flat tire. The location is indicated by a notch in the vertical bottom edge of the body side sheet metal."

Yeah gotta love the no good jack points on multi thousand dollar cars Gosh even the old VW Bugs had a better dedicated jack point.
The jack points should have a 3 or 4 inch round or square pad with a 3/4 hole and the jack should have a pin to fit in the hole.
Pinch welds once bent always bend that is the worse place in the world to jack at. And then of course the paint is removed during the jacking operation, causing a nice place for rust to start. Sorry auto engineers are not very bright.
 
I think repair shops lift the car by the bottom of the pinch weld as that's where their lift will lift the car.

However the factory jack for my Subaru uses the pinch weld to hold the jack inplace but the lifting force is on either side of the pinch weld. Not the actual pinch weld.
 
Pinch weld jack points are for roadside flat repair. Shops use subframe flat spots near suspension mounting points at the subframe for maintenance lifting. I never use pinch weld points for repair jacking. Many manuals show lift contact points.
 
This isn't a Malibu, but you get the idea. The lifting area for the emergency jack is the area in the rectangle.

I normally don't use pinch welds for lifting, unless it's with the emergency jack on the side of the road.

However, I will put jack stands (with a pad) there. The stand doesn't rest on the pinch weld proper; it straddles the pinch weld and contacts the body on either side. I feel comfortable doing this as the emergency jack pad contacts that area in the same way.
