2025 Chevrolet Traverse Body & structure Problems

The shark fin antenna cover became loose. The antenna then fell off at some point while driving. This coming off while driving poses a risk to others on the road as it may have fallen off and hit someone else. The only “warning” it gave was stating the emergency call system failure. When googling I found out what the problem may be from. After looking further there are multiple Chevy traverse owners with the same issue after going through a car wash.

Purchased the traverse January 10, 2026 with almost 26k miles on it. Approximately one month later, only 1200 miles or so into owning it, the shark fin antenna cover came off and is missing. It’s not the entire antenna that is hooked into the car, it’s only the plastic cover that covers up the electronics. This plastic piece randomly flying off the car put other motorists at risk, due to the plastic cover potentially striking another vehicles windshield distracting them from keeping their eyes on the roadway, striking another motorists vehicle causing damage to said vehicle, or even striking a person walking down the street potentially resulting in physical harm! I have talked with GM dealerships about this issues along with reading that numerous people have had the same issue, and they have yet to fix the problem.

The component that failed was the "shark fin" antenna cover. This houses the radio signal and hands free driving signals. The shark fin can be a safety concern if the cover fall off at higher speeds. The problem was reported to the dealer but was told it wasn't covered under warranty. It wasn't covered because according to them, I drive my car through automatic car washes. The antenna cover is not properly glued or clipped correctly. There has been no car failures or messages. It can cause other issues since the antenna is now exposed. Cannot give a clear answer on when the cover fell off I noticed it early December.

The cap to the antennae flew off the car. This could have potentially impacted a car driving behind me, a car passing me, and/or hit a pedestrian walking. There was no warning. The part has since been replaced however the dealer indicated other vehicles are having this issue.

One day My husband went to work and the antenna fin was attached, he came back home and it was no longer there . We do not car wash my car since its brand new. We hand wash it our selves there should be zero reason for that to come off. Apparently is a very common problem in the 2025 traverse. I joined a Facebook group and over 40 people had the same issue.

The antenna fin became detached and flew off as I was driving posing a risk to other drivers on the road. I was on an open highway when this happened. There was no damage to the fin prior to this.

The antenna cover (shark fin) on the roof of the vehicle detached while driving and flew off. Looking at the piece that flew off, the clips that are made to clip in and keep it attached to the roof broke off somehow and seemed to be very weak where some were still attached. The safety of other vehicles are put at risk by it being unexpected flying debris and could potentially hit a vehicle/motorcycle following behind or debris is the roadway. My dealer specifically has not seen many, but when researching online, it’s is a very common issue with the 2024 and 2025 Chevrolet Traverse. My vehicle was brought to my dealership and a person from the body shop will attempt to attach it back for a temporary fix until the issue can be resolved and not have to pay hundreds of dollars for something that the vehicle owner had no control over breaking. There was no warning of this attachment breaking off, nor should it be something that a vehicle owner should have to worry about replacing six months in of purchasing a brand new vehicle.

While driving with the front windows all the way up and the back windows all the way down at 60mph or higher the door panels vibrate real bad like they want pop off from the frame of the car, which is unacceptable. You should be able to drive with windows how you want to in you vehicle without your door vibrating like they want to pop off.

the car had a faulty door that would stick intermittently since the day we purchased it (march 10, 2025) and wouldn't open unless forced. we reported the issue on march 23rd to our sales rep (jorge) and didn't act upon it until two months later when it wouldn't open at all. upon bringing it into the shop on may 27th it was determined that there was a faulty latch. they also discovered that the brake light was on and the car was in need of multiple components - master cylinder, the adapter and the reservoir. we have had a rental car since 5/27/25 and yet to receive our car back.
