Timber! Mazda recalls 2.2 million vehicles for falling rear hatches

Almost 800,000 examples are located in the US and Canada.

I'm not saying to wear a helmet when you unload groceries, but I'm also not not saying that.

Road salt: Is there anything it can't ruin on a car? Good old-fashioned sodium chloride has once again spurred a vehicle recall. This time, Mazda's calling back millions of cars and crossovers because salt can screw with their rear hatches.

The recall affects the following Mazda models: 2010-2013 Mazda3, 2012-2015 Mazda5, 2013-2016 Mazda CX-5, 2016 Mazda CX-3. Over 2 million vehicles are included in the global recall, approximately 750,000 of which are located in the US and Canada.

It's all road salt's fault. According to the automaker, the anti-corrosion coating used on the trunks and hatches of the aforementioned models is insufficient. Thus, when water and road salt start getting into these supports, they can eat through the material and cause parts to break. When that happens, your trunk may come crashing down -- hopefully, not on your head.

To remedy the issue, Mazda dealers will replace both lift supports, which have likely been strengthened against road salt. The recall is not yet in effect, but customers will be notified this month or next as to when it will begin. In the meantime, maybe you should grab that old bike helmet out of the garage for your next trip to the grocery store.
