Corvette tragedy highlights problem with unique car controls

As tragedy demonstrates time and time again, there is true value in conventionally designed controls for vehicles. When an automaker comes up with inventive interfaces for traditional functions, it creates the risk that drivers may not be able to appropriately react in an emergency situation.

This confusing-controls issue has been repeated in cases of unintended acceleration in vehicles with push-button starters; an SUV on train tracks that couldn't move out of the way in time, supposedly because the driver couldn't figure out the gearshift stalk; awkwardly placed transmission buttons; and now, sadly, to an older driver and his dog who succumbed to heat exhaustion when they were trapped in a 2007 Chevrolet Corvette.

This week in Texas, an elderly man was unable to open the door to his Corvette on a hot day. News reports point to a problem that cut off power in the car, rendering the electric door switches inoperable.

In the sixth- and current seventh-generation Corvettes, rather than traditional hinged door-release handles inside and out, electric buttons release the door. This approach likely shaves ounces from the production vehicle and enables a clean, aerodynamic exterior.

However, it doesn't truly solve a consumer need. And it can put occupants in peril. If the interior pushbutton release fails to work—say if the battery is dead—a redundant mechanical release is located alongside the driver and passenger seats, akin to a common fuel-filler release lever. If working properly, this would allow an otherwise trapped occupant to exit—assuming they know where to look. (Watch a video demonstration.) In addition, most Corvette coupes of that era came with a removable top that could be manually operated.

Looking through our car reliability data, we see that problems with door locks and latches are among the most common complaints. But there isn't any worrisome trends among Corvettes.

The takeaway

A key lesson from such tragic tales is to read your owner's manual. Today's cars have more features than ever, including some you may not even realize you have. Indeed, a quick look at Corvette forums show that some owners—and dealer sales staff—don't know this release exists.

No matter what car, by reading through the manual, you will be better versed in the vehicle's operation and be able to get the most from the ownership experience. Be sure to return the manual to the glove box when done. Likewise, when buying a new car, don't rush from the showroom as soon as the paperwork is signed. Allow the salesperson to give you a proper tour of the car and its key features.

While it is hard to prepare for every random, unexpected scenario, consider keeping a self-rescue tool in your glove box. Such compact tools typically offer an easy means to cut the seat belt and break the side glass in case an escape is needed.

For manufacturers, we hope such events remind them that consumers need simple solutions. As cars become stunningly complicated, their core function remains to transport people safely from Point A to Point B. Unique takes on common functions often don't aid that basic mission.
