J.D. Power dependability survey is out, but you shouldn't depend on it

J.D. Power has just released its latest automotive dependability survey, which of course has usual suspects Buick and Lexus ranking high. Those are safe and solid findings, surely. But when you look a little closer, there are curiosities. Our Consumer Editor, Jeremy Korzeniewski, offered an explanation a couple of years back for why this survey should be viewed with a degree of skepticism, and his take is worth a re-read. What jumped out at Jeremy were the relatively low spots assigned to Mazda, Subaru and Scion among the ranking of makes. Back in 2016 when he wrote his piece, they were ranked 21st, 23rd and 24th respectively. In this year's survey, Mazda ranks 15th and Subaru 26th, both below the industry average of 142 reported problems per 100 vehicles. (And Scion, of course, is in car-brand heaven.) Now, part of what is going on here is surely the fact that all automotive brands are producing dependable vehicles compared with years gone by, so the degree of variance between the best and worst on the list is not as great as it once was. "For the most part, automotive manufacturers continue to meet consumers' vehicle dependability expectations," Dave Sargent, a J.D. Power vice president, said in a statement. "A 9 percent improvement is extremely impressive, and vehicle dependability is, without question, at its best level ever." That said, when a brand like Subaru, regarded by many as mechanically bulletproof, ranks 26th, it leaves people who know cars scratching their heads. Something there does not compute. The problem, as Jeremy pointed out, is one of methodology: When he wrote his piece, there was no weighting assigned to the problems reported in the survey. And that still appears to be the case. Therefore, a problem with an infotainment system or a loose piece of trim is deemed as serious as a blown engine or leaky transmission. (And yes, infotainment is still the biggest problem across the board.) Jeremy's point: If the categories of problems were weighted, you'd see a different picture. When you look at the Consumer Reports brand rankings (subscription required), you get a very different picture. in CR's rankings, Subaru is No. 6 among brands, which, well, sounds a lot more like it. CR singles out the redesigned 2017 Impreza as a car with some new-model problems. (The BRZ had the fewest.) The two surveys jibe a little more closely when it comes to Mazda, which CR ranks 12th, a drop of six places from previous-year rankings.

2019 Mazda CX-5 fuel economy takes a hit with new turbocharged engine

We learned all about the 2019 Mazda CX-5 last week, and now we've discovered fuel economy for its new 2.5-liter turbocharged engine. Unsurprisingly, it gets slightly worse fuel economy than its naturally aspirated counterpart. The 2019 turbo crossover, which only comes in all-wheel drive form, gets 22 mpg city and 27 mpg on the highway. Front-wheel drive CX-5s with the naturally aspirated 2.5 liter net you 25 mpg city and 31 mpg highway — all-wheel drive drops 1 mpg in both categories. For a little comparison, the turbocharged engine makes 250 horsepower and 310 pound-feet of torque on 93 octane gasoline, while the non-boosted engine makes 187 horsepower and 186 pound-feet of torque. You're definitely taking a hit in fuel economy, but the gain in power might be worth it, since the decrease isn't that terrible. Cars in its price and power range with all-wheel drive have comparable fuel economy. The Ford Escape with the 2.0-liter turbo is rated at 20/27; Chevrolet's Equinox with the 2.0-liter turbo is 22/28 and the VW Tiguan gets 21/29. There isn't really a clear winner in fuel economy for this much power when you look around the segment, but Mazda's engine is half a liter larger than everyone else. This translates to better torque than most of its competitors, but Mazda manages similar fuel economy. Also similar to many of these decked-out compact crossovers is the new high price of the Mazda we wrote about before. You won't be getting in to the turbocharged CX-5 for any less than $35,865. If you wanted a bigger Mazda like the CX-9, its fuel economy figures aren't significantly worse than the CX-5. Front-wheel drive versions are rated 22/28, and it drops 2 mpg in each category for all-wheel drive. The updated 2019 CX-5 should be coming to dealers soon.

White House clears way for NHTSA to mandate vehicle black boxes

At present, over 90 percent of all new vehicles sold in the United States today are equipped with event data recorders, more commonly known as black boxes. If the National Highway Traffic Safety Administration gets its way, that already high figure will swell to a full 100 percent in short order.
Such automotive black boxes have been in existence since the 1990s, and all current Ford, General Motors, Mazda and Toyota vehicles are so equipped. NHTSA has been attempting to make these data recorders mandatory for automakers, and according to The Detroit News, the White House Office of Management Budget has just finished reviewing the proposal, clearing the way. Now NHTSA is expected to draft new legislation to make the boxes a requirement.
One problem with current black boxes is that there's no set of standards for automakers to follow when creating what bits of data are recorded, and for how long or in what format it is stored. In other words, one automaker's box is probably not compatible with its competitors.
