General Motors is recalling certain 2011 through 2014 Chevrolet Volt extended-range electric cars, but only as a matter of "customer satisfaction."

In the affected cars, the struts that hold the rear hatch open can weaken and detach, causing the hatch to close by itself unexpectedly.

While no one wants to get struck in the head by a car's rear hatch, the problem was deemed not severe enough to warrant an official recall.

That's because it doesn't interfere with the operation of the car or its safety equipment.

The company isn't calling this a recall either, instead referring to it as a "Customer Satisfaction program."

GM has been informing Volt owners of the hatch-strut issue, but it won't be listed in the official National Highway Traffic Safety Administration (NHTSA) database, according to Transport Evolved.

Because of that, it's unclear how many cars are affected.

The issue, however, applies to almost the entire production of the Volt from 2010 through the 2014 model year, as well as 2010 through 2015 Cadillac SRX crossovers.

GM will continue to notify owners, and it will arrange to have the hatchback struts on affected vehicles inspected--and replaced if necessary--free of charge.

Some owners will be informed of the issue through their cars' OnStar telematics system, while others will be informed via mail.
