What the Feds Are Doing to Your New Car
It’s the “bells and whistles” that get the headlines – and grab your attention. But they might also grab your wallet once the warranty runs out. A classic example from long ago is the aluminum block four-cylinder engine GM trotted out back in the mid-1970s. It was a revolutionary design based on a high-silicon alloy that eliminated the need for pressed-in cylinder liners. It was also very lightweight, which promised to improve both the fuel economy and the handling of the car it was built for – the Chevy Vega. Stop me if you know where this is going…
No?
Well, the problem wasn’t the alloy block. It was the cast iron cylinder head bolted to it. And the unbalanced pistons within, which shook like a shivery dog on deliberately loose motor mounts (a Band Aid for the shivery shaking, to mask it from the car’s owner) until either the head bolts loosened up or the block warped just enough to let coolant slip past the head gasket into the unsleeved cylinders.
Hello, ‘Frisco!
Few of these atrocities ever made it to 30,000 miles without a catastrophic engine failure.
Such epic debacles are less common today. But modern cars are far from foolproof. Here’s a roster of some designs – and features – you might want to think twice about:
* AC and audio controlled by touchscreen input –
The iPad Culture craves flat screens – including in their cars. Here’s the problem. When your touchscreen LCD croaks, your AC and audio system (as well as anything else controlled via the touchscreen) will no longer work. Or rather, you won’t be able to turn these accessories on (or perhaps, off).Mechanically speaking, there may be nothing wrong with your AC. The compressor, condenser and so on all working properly. But with a dead flat screen – or one no longer responsive to your touch – you’re looking at a big repair bill regardless. Areplacement repair bill, actually. Because you don’t repair dead LCD displays. You pull them – and toss them. How much does a new iPad cost? Physical buttons and knobs, meanwhile, are pretty dependable and more important, individual. One knob or switch or button controls one thing. If the little knob you rotate to adjust the radio’s volume goes out, you won’t be able to adjust the volume… but your AC will still work. If the LCD touchscreen craps out, nothing works.
You’ve been warned.
* 20 inch (and larger) wheels –
This ghetto inspired trend has reached the apotheosis of stupidity. Everyone seems to want their car – or SUV – to look like a Suge Knight Special. Leaving aside the aesthetics, these oversized “rims” dramatically increase rolling resistance, which dramatically hurts gas mileage. They also dramatically increase wear and tear on front end components – which you’ll find out about around 30,000 miles down the road from new. They muck up ride quality – which the car industry crutches via elaborate (read: expensive) suspension systems in order to make the cars livable. “Twennies” mounted on 4WD on SUVs are the absolute height (depth) of idiocy. The last thing you want on a 4WD are short/stiff sidewall tires and a steamroller tread that rides up on rather than cuts through the snow.
