GM to Stop Sales of Silverado and Sierra for Roof Splitting Issue
General Motors is one of the largest pickup truck manufacturers in the world, with its Chevrolet Silverado and GMC Sierra two of its more popular models. While the most recent iterations of the two full-size pickups are more refined and tech-forward than previous generations, the 2024 models appear to also have a problem with their roofs splitting.
GM-Trucks.com reported on the issue, in response to which General Motors issued a stop sale for the two trucks. While the automaker has not identified specific affected models or configurations, it said that around 3,067 vehicles in the U.S. are included in the action. The problem relates to the trucks’ roof panels, which can begin to split open on the passenger side. Though the damage is typically hidden by the roof molding, it can cause corrosion, leaking, and a safety issue during a crash.
Unlike many recent recalls and safety issues, this problem cannot be fixed with a software update. Dealers will drill the ends of the cracks to stop the spread, and MIG weld the underside of the roof. The truck then needs to be repainted and clear-coated to finish the job, and dealers will also apply an anti-corrosion solution on the welds.
This action could affect vehicles sitting on dealers’ lots, so the stop-sale is intended to have them fixed before they leave the showroom. Affected owners will have the repairs performed for free under warranty and may receive a loaner car.

as a body shop owner after looking at the picture, it looks like a stress crack from stamping {factory defect] our shop has replace many roof panel on trucks from holes in roof and tree limb damage, welding with a mig welder is a no -no, because the metal is too thin and also it could cause electrical feedback to the electronic system even if the battery has been disconnected, it can also damage sensors, a better way is to braze the metal with low heat where the brazing is flow into the seams, body work and refinish is require to the complete the job, only experience body shop can perform that job, the average price will cost around 3 grand, and gm will only pay 10 hours and that is only around 800 dollar, so imagine the can of job you will get under warranty,

Oh no, but I think you'll find

Oh baby, I'll be there
My understanding is that the cracks are limited to the driver’s side under the rubber roof gasket and ‘Jimmy’ll Fix it (sorry, couldn’t resist the pun) isn’t a FIX but a patch/plug. Jimmy’ll fix it by drilling a hole at both ends of the fissure and doing A TIG weld else gooping BONDO into the drill holes & painting it over. I say ‘F’ (150) that!!!!
The problem is that the GMC is using High Strength Steel which, by definition doesn’t flex. What does that mean? Every time you back out or go up yer drive way, you are flexing yer weaken roof. It’s like a drummer’s symbol—-once you crack it, it will crack again. Well, I ain’t paying $75k for a truck I have to baby—A truck is like a Border Collie she has to earn her keep by working as hard as I Do!!!!
TTAC needs to hire a structural engineer and tell us if it is a design or MFGR defect
