Roof strength is pretty important and one automaker is causing concern. The Chevrolet Colorado and its fraternal twin, the GMC Canyon have a problem with denting easily. This comes after the Chevy Silverado and GMC Sierra roofs were splitting apart. 

The Chevy Colorado and GMC Canyon roofs are denting at car washes 

There have been various complaints about how easily the roof of the 2023 Chevy Colorado and GMC Canyon may become dented during an automatic car wash. 

Imagine washing your truck after getting it muddy or covered in road salt and finding that your roof integrity is a little weak as it fills with dents. 

This is a concern for the entire truck’s structural integrity and safety during accidents. A roof and frame are supposed to support the entire weight of the vehicle so passengers don’t get crushed. Also, the dents take away from the truck’s look. 

Anyways, the force of some automatic car wash dryers may cause the roof to flex. General Motors released technical service bulletin (TSB) 23-NA-209 to address this issue, so hopefully your truck won’t have dents for too long. 

During an automatic car wash, you might hear oil canning or pop coming from the roof area. If the roof flexes or has dents, then technicians will repair the roof damage and then apply stiffening patches to the underside of the roof panel.

To complete this procedure, the roof liner will be dropped but not fully removed. Then five stiffening panels will be added to the front of the roof and the liner will be replaced before the correction is verified. 

It’s unclear how long this procedure will take, but the dealer instructors include a patch description, part number 1582853, and a quantity of five. We wouldn’t be surprised if this issue spawns a recall, even if it’s primarily a cosmetic problem. 

Reportedly, this problem isn’t related to the 2024 Chevy Colorado and GMC Canyon models. Maybe they’re getting the extra panels during the manufacturing process now. 

Also, it’s unclear if those who have already paid for this repair will be reimbursed. Hopefully, this is a defect that’s covered under warranty. Stay tuned for updates as we track this growing problem.
