Mazda recalls 2019-2020 Mazda3 for errant activation of emergency braking system

The newly redesigned Mazda3 has been subject to numerous recalls since it went on sale for the 2019 model year. Today brings news of another such occurrence, as Mazda recalls 35,390 2019-2020 Mazda3s (sedans and hatchbacks). This recall is related to the automatic emergency braking system equipped to certain models. According to Mazda, affected vehicles may “unexpectedly stop while driving due to inadvertent activation of the Smart Braking System automatic emergency braking system.” The programming of the systemÂ’s software could cause the Mazda3 to “falsely detect an obstacle in front of the vehicle while driving.” In response to that detection, the software may automatically apply the brakes despite no collision being imminent. We donÂ’t have to explain how dangerous that could end up being for the driver and those around them. Your car slamming on the brakes for no reason could easily be the cause of an accident. As of now, Mazda says no injuries or deaths have been reported as a result of the defect. In case you havenÂ’t experienced the system in your Mazda3 yet, there is something to look out for. Mazda says a warning alarm will sound and a warning message will appear in the instrument cluster and head-up display when the car is about to perform an emergency stop. Mazda said that itÂ’s reported the defect to the NHTSA, but it hasnÂ’t been posted on the website yet. The fix is easy for some, but more difficult for others. Vehicles with early build dates will need the whole instrument cluster replaced or reprogrammed, as these cars have a different procedure for "temporary manual deactivation of the Smart Braking System." These early build cars will also receive a new owner's manual to reflect the revised procedure of temporary manual deactivation of the system. Later cars will only need the Smart Braking System software reprogrammed with an improved version. Mailings to owners for notification purposes should be completed on or before February 17 next year.

Mazda says Skyactiv-X will come to the U.S, but not when

Mazda executives say the new 2.0-liter Skyactiv-X powerplant will still take some time to arrive to the North American market. The Skyactiv-X is a high-compression gasoline engine, and its 16:1 compression ratio is comparable to that of a diesel engine. "We have a lot of technology. And we are introducing each technology in each region when the time is right," said Mazda North America CEO Masahiro Moro at the SAE International WCX Conference, according to Automotive News. Moro stated that while the Skyactiv-X can indeed pass EPA emissions regulations, it's not in the immediate pipeline for U.S-bound Mazdas; the slightly less hardcore Skyactiv-G will be amended first. The launch-spec 2.5-liter Skyactiv-G engine in the new Mazda 3 will reportedly be supplemented by a 2.0-liter Skyactiv-G, which also has a bold compression ratio: according to Mazda, its ratio of 14:1 is the highest of any production gasoline engine. However, Moro didn't state the exact timeline for that Skyactiv-G's arrival, either. The compression ratio of the 2.5-liter "big block" available now is 13:1. In the 2019 model-year Miata roadster, the 2.0-liter Skyactiv-G makes 181 horsepower, and an earlier Slovakian Euro-spec leak mentioned the 2.0-liter 3's power figure at 164hp. The bottom line is thermal efficiency through being able to extract more energy out of gasoline, and moving from G to X would improve fuel economy by 20-30 percent while giving more power. If the Slovakian specifications are to be believed, the Skyactiv-X would make 178h p and 164 lb-ft in the Mazda3.
