When a vehicle exhibits poor reliability, it’s easy to blame the design engineer.
But that may ignore a larger problem.
A recent survey of automotive brands by Consumer Reports suggests that reliability -- good and bad -- runs deeper than the engineering department. In most cases, it can be traced all the way back to the manufacturer’s corporate philosophy. “There’s no doubt in my mind that the engineers at Chrysler, Tesla, and Toyota are all very smart and capable,” Jake Fisher, director of auto testing for Consumer Reports , told Design News . “The difference lies in the priorities set by the management of those companies.”
Indeed, corporate priorities spell the difference between reliable and unreliable brands, Consumer Reports says. Using data on more than half a million vehicles, including 300 models from 2000 to 2016, the organization predicted the future reliability of established models. And, because corporate philosophy matters, fleet averages played a big role in those predictions.
That’s why Toyota vehicles are consistently at or near the top of the organization’s massive owner surveys, while Chryslers and Fiats consistently bring up the rear, Fisher said.
Fisher contends that automakers who place a high value on tried-and-true technologies, as opposed to complex, high-tech gadgetry, do better in reliability. “With Toyota, we don’t see a lot of small displacement turbos,” he said. “We don’t see a lot of dual clutch transmissions. Those are the technologies that are bogging down some of the other manufacturers.”
Not surprisingly, manufacturers who “nickel-and-dime” their suppliers also suffer in owner surveys, Fisher said. That’s because suppliers who deal with big, high-volume automakers will always aim to please. “An automaker can go to a supplier and say, ‘We want the water pump with the lowest price,’” he said. “Or they can say, ‘We want the part with a simulated life of 300,000 miles.’ Suppliers will meet whatever criteria they’re being judged on.”
The simple takeaway from the Consumer Reports study is that product reliability improves when manufacturers care about -- product reliability. That’s why, for the second straight year, Consumer Reports engineers factored fleet averages into their predictions of future models. When forecasting reliability, a top-down emphasis matters, they said.
“It’s about the common practices of the manufacturers and the consistency of the brands,” Fisher told us. “You can judge a lot about a manufacturer by looking at the quality of their fleet.”
