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.

2019 Mazda3 gets only two engines in U.S.; here are details on suspension, AWD

We learned a lot about the 2019 Mazda3 hatchback and sedan when it made its debut at the L.A. Auto Show. It will still have a manual transmission, it will offer all-wheel drive for the first time, and it's a stunner inside and out. But we still had questions about some of the details, so we spoke with folks from Mazda, including a couple of engineers for details on engines, suspension and drivetrains. First off, of the five engines announced for the Mazda3, just two of them are slated for the United States. At launch, the Mazda3 will be offered only with a naturally aspirated 2.5-liter four-cylinder. It's mechanically pretty much the same as what you'll find in the Mazda CX-5 and Mazda6. It even features cylinder deactivation. The only real difference between this engine, its predecessor, and the one in other Mazdas is some minor engine tuning tweaks. Power is almost the same with 186 horsepower and 186 pound-feet of torque, gains of 2 horsepower and 1 pound-foot. Fuel economy is rated at 27 mpg in the city, 36 on the highway, and 30 overall for front-wheel-drive models. We would expect the all-wheel-drive model to have slightly worse fuel economy simply due to extra weight and having to power two extra wheels. The Skyactiv-X engine will become available later in 2019. It will be rolled out in Europe first, with America coming after. When it does come here, it will be offered in states with stricter emissions regulations before coming to other states. While we're on the topic of engines, we also probed a bit about the possibility of the turbocharged 2.5-liter engine coming to the Mazda3. We did get the typical response of not being able to comment on future product. However, they did confirm that the turbocharged engine does in fact fit in the new Mazda3, since it and the naturally aspirated engine are very similar, and the naturally aspirated engine still uses an enormous header, meaning turbo plumbing wouldn't be an issue. Everyone we spoke with at Mazda did emphasize that they are listening closely to buyers, which is what led to the turbo engine being offered on the Mazda6 and CX-5, as well as the introduction of all-wheel-drive to the Mazda3. So, if you, like us, want to see the turbo engine added to the Mazda3, let the company know. They might just do it. Now as for drivetrains, the company is still deciding which trims and which combinations of engines will be offered.

Mazda CX-5, Mazda6 and Mazda3 could stall due to software glitch

Mazda is recalling 262,220 vehicles due to a software error that could cause the engine to unexpectedly stall out. The recall affects 2018-2019 CX-5 crossovers, 2018-2019 Mazda6 sedans and 2019 Mazda3 models.  According to NHTSA recall No. 19V497000, which was filed June 27, a programming issue in the powertrain control module (PCM) on select Mazda vehicles could cause the engine to shut down. More specifically, "the software controlling the hydraulic valve clearance adjuster may operate improperly when transitioning from cylinder deactivation to full cylinder activation modes." This could potentially cause the intake valve rocker arm to come out of position and hit something else in the engine. If this occurs, the engine could misfire, the engine could lose power, and the Malfunction Indicator Light would be triggered. The recall affects 143,004 2018 CX-5s, 81,236 2019 CX-5s, 18,295 2018 Mazda6s, 2,551 2019 Mazda6s, and 17,134 Mazda3s. Some cars from those model years received the improved software at the factory and won't be affected by the recall. Although the first report of a related issue was chronicled in January 31, 2018, no injuries tied to the problems have been reported. Mazda is expected to start its recall on or before August 26, 2019, and will reprogram the PCM with improved hydraulic valve adjustment control programming for free.
