NHTSA investigating 725k Ford, Mercury vehicles for stalling issue

Owners of Ford Escape, Mercury Mariner, Ford Fusion and Mercury Milan models, listen up. According to a report on Automotive News, the National Highway Traffic Safety Administration has opened an investigation into these four vehicles totaling an estimated 725,000 units. The investigation appears to center around a malfunctioning throttle body on non-hybrid models of the 2005-2012 Escape and 2011-2012 Fusion. With Mercury dying off after the 2011 model year, this probe will also apply to the 2005 through 2011 Mariner and the 2011 Milan. There has been some discussion around the Escape stalling issue for some time now, but this investigation appears to be larger in scope than before.
Though not a recall yet, NHTSA's Office of Defects Investigation (ODI) has received 123 complaints of stalling or surging vehicles, while Ford itself has logged 1,472 complaints. The investigation report, which is posted below, seems to indicate that a faulty circuit board for the throttle body could cause the vehicle to go into limp mode, which, according to NHTSA, could cause complaints of both stalling and surging.

2015 Ford Mustang EcoBoost loses big power on 87 octane

The 2015 Ford Mustang with the 2.3-liter EcoBoost four-cylinder is a pretty potent package on paper. With 310 horsepower and 320 pound-feet of torque, it boasts better performance numbers than the 3.7-liter V6, but with better fuel economy as an added benefit. However, if you're in the market for one of these boosted 'Stangs, you should probably keep in mind that it really prefers to gulp premium, 93-octane fuel. It can drink 87-octane swill in a pinch, but you're going to find significantly less power underfoot when pulling away. While it's not shocking that the ponies are dialed back with a lower grade of gasoline, an alleged page from a Ford training manual obtained by Mustang 6G purports to show just how much power is lost, though. According to this document, the 2.3-liter EcoBoost makes 275 horsepower and 300 pound-feet of torque when running on lower octane fuel. That's a substantial reduction of about 11.3 percent compared to when the engine drinks 93 octane. Interestingly, according to Mustang 6G, that finding was a bit better than expected, because a Ford engineer reportedly said power would be down about 13 percent without altering peak torque. In speaking with Autoblog, Paul Seredynski of Ford powertrain communications, objected to part of this document. While he couldn't confirm the specific losses listed for the Mustang EcoBoost, "torque remains unchanged" with lower octane gasoline, Seredynski said. He speculated this training manual page was "possibly from before the engine was certified" and therefore showed incorrect figures. Serendynski did confirm that the automaker recommends using 93 octane, and like all modern engines, the software adapts if it's lower. "Peak power would be reduced" by using a lesser grade, he confirmed.

Sunday Drive: Big debuts from the Big Apple dominated the headlines

New York Auto Show week has come and gone, and, not surprisingly, the week's biggest bits of news came from the halls of the Jacob K. Javits Convention Center in NYC. Our favorite debut from New York was the Lincoln Aviator, a sharp-dresses crossover that looks lovely inside and out, and sits on underpinnings at least partly derived from the Ford Mustang. While the Aviator may have caught our attention, it wasn't the most popular vehicle debut from New York, at least when judging by the number of page views here on Autoblog. That distinction goes to the 2019 Toyota RAV4, and we're hardly surprised. The RAV4 is the most popular compact crossover in America (in fact it's the most popular vehicle that isn't a pickup truck), and the 2019 version looks like a radical departure from the model that came before. We can't wait to drive the thing. Midsize sedans may not be the darling of the family car set, that honor taken over by the aforementioned crossover, but they still sell in large enough numbers that a brand-new model catches our attention. Such is the case with the 2019 Nissan Altima. We broke down the specs of the Altima and compared Nissan's bread-and-butter sedan with its biggest rivals. And finally, we got some official figures for the 2019 Ford Mustang Bullitt. It'll cost a cool $12,000 over the cost of a Mustang GT, and will benefit from a 480-horsepower, 420-pound-foot version of Ford's excellent 5.0-liter V8 engine. As always, stay tuned this week for all the latest automotive news that's fit to print. 2018 New York Auto Show Mega Photo Gallery | Start spreading the news 2019 Toyota RAV4 actually looks pretty cool 2019 Nissan Altima vs Honda Accord vs Toyota Camry: How they compare 2019 Mustang Bullitt orders open as Ford reveals price and horsepower Image Credit: Drew Angerer/Getty New York Auto Show Ford Lincoln Nissan Toyota Coupe Crossover SUV Sedan 2018 new york auto show
