Five automakers now being investigated by NHTSA for airbag woes

It appears that Toyota's renotification to owners of recalled vehicles from last year is just the tip of the iceberg for what could potentially be a much larger industry-wide recall. The National Highway Traffic Safety Administration is opening a preliminary evaluation investigation into roughly 1.1 million vehicles from Chrysler, Honda, Mazda, Nissan, Toyota and parts supplier Takata regarding faulty airbag inflators in several models.
NHTSA has received six reports - three directly, two from Takata and one from Toyota - of vehicles with ruptured airbag inflators from 2002-2006, which resulted in three injuries. So far, all six incidents have occurred in high humidity areas like Florida and Puerto Rico. According to Toyota's latest recall announcement, the inflators may have an improper propellant that could cause it to rupture in a crash and the bag to deploy abnormally.
This new investigation follows a previous recall from April 2013 of about 3.4 million vehicles worldwide for the airbag inflators from Takata. As Autoblog reported, Toyota jumpstarted the new situation when it found that the original list of serial numbers for the faulty part was incomplete and discovered more cars in need of replacement. Honda and Nissan told us that they were investigating whether further models would need called in again as well. Mazda told Autoblog: "Regarding the current Takata situation, we're working closely with NHTSA and investigating the situation, but nothing else to report at this time." Chrysler Group responded to us with the statement: "Chrysler Group engineers are conducting the appropriate analysis. The Company will cooperate fully with the National Highway Traffic Administration."

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.

Mazda recalls 193k CX-9 crossovers over corroded suspension

An issue with the suspension on the CX-9 has prompted Mazda and the National Highway Traffic Safety Administration to recall 193,484 vehicles across the United States. The campaign specifically affects units from the 2007-2014 model years, manufactured between October 24, 2006, and December 28, 2013. In those affected vehicles, the ball joints in the front suspension may corrode due to water leaking into the fitting. According to the statement below, if the ball joint rusts, the front lower control arm could separate, resulting in a loss of steering control. And needless to say, that could lead to a crash. To repair the issue, Mazda will have to replace both the left and right lower control arms, and will naturally do so free of charge, but will undertake the repairs in stages. First, owners of the affected vehicles will receive a notification that a recall campaign is under way. Then they'll get a second letter when the parts are ready and they can bring their vehicles into their local dealers. The company will start first with 2007-09 vehicles, specifically those registered in the snowy states of the Northeast and Midwest. Specifically: Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin, and Washington, DC. (Oddly, states in the the western portion of the Midwest, as well as the Rocky Mountains and the Pacific Northwest, were not included in that initial phase. Nor was Alaska, for that matter.) After that they'll call in 2010-14 models in the same states before undertaking repairs on vehicles in other areas to the west and south.

The affected vehicles have front suspension ball joints that may corrode from water leaking into the fitting. CONSEQUENCE: Over time, the ball joint corrosion may result in the front lower control arm separating from the ball joint, causing a loss of steering control and increasing the risk of a crash.
