Chevy Equinox Windows Have A Problem With Loud Music

Industry News / Comments

GMC Terrain owners are affected, too.

We've long known that listening to loud music is bad for your hearing. It doesn't matter whether you're using headphones or listening to the stereo in your home or car. Loud is loud. And if you're the owner of a 2018-2021 model year Chevrolet Equinox or GMC Terrain, then you should be aware of a new technical service bulletin (TSB) from General Motors first noticed by GM Authority.

The problem involves the crossovers' power window motor losing memory because of intense speaker vibration. More specifically, the front windows could lower by approximately one-quarter of an inch or more if the audio system is too loud or is playing music with heavy bass.

Affected drivers may also see an "Open Then Close Driver Window" message displayed in the gauge cluster. This is not a safety risk but it is something that can be extremely annoying and needs to be resolved. Fortunately, there's already a solution.

Dealers will install foam between the window motor and the inner door panel, which should dampen any vibrations from the speakers. Both vehicles already come with foam for this very reason but, evidently, it's not enough. The TSB provides specific instructions for technicians on how to install the additional foam. The automaker will notify those affected so they can schedule a repair time at their convenience.

It's important to understand that a TSB is not a recall, hence this situation not being considered a safety risk. But it definitely wouldn't be pleasant when outside wind noise and truck fumes come barreling into the cabin. GM didn't state specifically how many vehicles are involved but it's not every Equinox and Terrain built during those model years. What's also unknown is how the problem was discovered.

The Equinox was originally scheduled for a mid-life facelift for the 2021 model year but this was pushed back to 2022 due to pandemic-related supply and manufacturing problems. It's highly unlikely this specific window issue will be carried over to the upcoming model year.
