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.

Ford made three big mistakes in calculating MPG for 2013 C-Max Hybrid

It's been a rough time for the official fuel economy figures for the Ford C-Max Hybrid. When the car was released in 2012, Ford made a huge deal about how it would beat the Toyota Prius V, which was rated at 42 combined miles per gallon, 44 city and 40 highway. The Ford? 47 mpg across the board. How did Ford come to this place, where its Prius-beater turned into an also-ran? Well, after hearing customer complaints and issuing a software update in mid-2013, then discovering a real problem with the numbers last fall and then making a big announcement last week that the fuel economy ratings of six different 2013 and 2014 model year vehicles would need to be lowered, the C-Max Hybrid has ended up at 40 combined, 42 city and 37 highway. In other words, the Prius trumps it, as daily drivers of those two vehicles have known for a long time. The changes will not only affect the window sticker, but also the effect that the C-Max Hybrid (and the five other Ford vehicles that had their fuel economy figures lowered last week) have on Ford's compliance with greenhouse gas and CAFE rules for model year 2013 and 2014. How did Ford come to this place, where its Prius-beater turned into an also-ran? There are two technical answers to that question, which we've got below, as well as some context for how Ford's mistakes will play out in the bigger world of green vehicles. Let's start with Ford's second error, which is easy to do since we documented it in detail last year (the first, needing to do a software update, was also covered). The basic gist is that Ford used the general label rule (completely legally) to test the Fusion Hybrid and use those numbers to figure out how efficient the C-Max Hybrid is. That turned out to be a mistake, since the two vehicles are different enough that their numbers were not comparable, despite having the same engine, transmission and test weight, as the rules require. You can read more details here. Ford's Said Deep admitted that the TRLHP issue is completely separate from the general label error from last year. Now let's move on to last week's announcement. What's interesting is that the new recalculation of the MPG numbers – downward, of course – was caused by a completely separate issue, something called the Total Road Load Horsepower (TRLHP). Ford's Said Deep admitted to AutoblogGreen that the TRLHP issue had nothing to do with the general label error from last year.

I'm Senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. Super Duty is new for 2017. Our first look at these heavy duty trucks showed increased cab space for passengers, and [00:00:30] a lighter aluminum frame. Ford insists these changes will provide customers with increased towing capacity and fuel efficiency. The all-new Super Duty will be built at Ford's Kentucky Truck Plant, and it goes on sale in late 2016. Now, in case you missed it Volkswagen is under fire for gaming EPA emissions testing. A massive government recall is in the works and the world's top-selling automaker is looking at significant losses in both car sales and its stock value. On top of losing billions of dollars, Volkswagen is also facing [00:01:00] legal issues. And this week we saw Martin Winterkorn step down as CEO of Volkswagen Group. These changes mark just the beginning of VW's arduous process of rebuilding consumer trust. Those are the highlights from the week that was. Be sure to check out my full recap this Saturday, plus some added insight on the Buick Cascada and its pricing strategy. For Autoblog, I'm Greg Migliore.
