Top 5 New Car Technology Blunders

We’ve come a long way from the seat-belt-interlock system of 1974. That system required every occupied seat to have the belt fastened before a car would start, and as you can guess this short-lived example of safety technology was an overbearing intrusion consumers didn’t like. As a former 1974 Pontiac Firebird owner I can confirm how annoying this particular “safety enhancement” was every time I had to move the car a short distance on the driveway or in a parking lot.

Idle Stop Start

1. Fake Exhaust Noise: Modern carmakers work hard to create the right exhaust note. Some brands have been doing it for decades, but today every performance car sounds amazing…including the BMWs that use speakers instead of explosions to power their exhaust roar. They do this because modern cabin insulation effectively blocks engine noise and/or because the vehicle in question (in this case the 3-cylinder i8) doesn’t have an engine capable of producing a powerful exhaust note. Routing an engine’s actual exhaust note through different baffles is an alternative many automakers use to solve the problem, which is fine.

2. Idiotic Idiot Lights: A friend of mine recently took his 2013 Ford Escape on a road trip. It performed flawlessly on the 2000-mile drive from Denver to Florida, but as he rolled into his destination every warning light on the dashboard — ABS, Traction Control, Airbag — lit up. A message stating “hill climb assist not available” also came up. After thinking the drivetrain might have fallen out he took the car to a local Ford dealer. The problem? A faulty airbag wiring harness. Did that issue really require half-a-dozen warning lights? Our cars are supposed to be smarter than ever, with diagnostic ports that tell mechanics exactly what’s wrong. Why can’t they tell us, too, with a simple (and accurate) message in the display screen?

3. Virtual Buttons for Critical Functions: Today’s ubiquitous touchscreen displays let automakers clean up the dashboard control interface. With so many features that didn’t exist 20 years ago (stability control, sport modes, dual-zone climate control, hands-free phone operation, navigation, etc.) a touchscreen can literally replace dozens of hard buttons that would otherwise clutter the cabin. That’s fine, but when Tesla’s Model S makes basic functions, like the rear hatch release and charge port access, dependent on these digital buttons it sets up a potential nightmare if (when?) the display screen fails.

4. Electric-Powered Doors: Like touchscreen buttons, automakers have begun using electronic relays to replace the mechanical door release in cars like the Chevrolet Corvette. As with most high-tech features, this system usually works fine, popping the door open at the touch of a button. But — what happens when the battery dies and the car loses all electrical power? Thankfully, automakers are required to offer mechanical alternatives for these occasions, though the process can be far more involved and far less intuitive than pushing a button. Imagine you’re in an accident that damages the electrical system while also starting a fire. 

5. Misplaced Keyless Start: The idea of not having to twist a key, or even touch a key, when starting or shutting off your car sounds great. Now imagine you’ve driven to the airport with your significant other, who proceeds to get out of the car and onto a plane bound for the other side of the globe. Only after you’re halfway home do you realize the car key is in your partner’s pocket. These systems are supposed to have sensors that warn you when the key isn’t in the cabin. And more than a decade after this technology was introduced the majority of cars I test still make the airport scenario plausible. Automakers need to make these systems fool-proof, which means accurate sensors that immediately identify when the key isn’t present.
