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 finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.

NHTSA advances investigation of Ford Crown Victoria headlights

The National Highway Traffic Safety Administration is opening a preliminary evaluation into reports of suddenly failing headlights on 517,945 examples of the 2003-2005 Ford Crown Victoria and Mercury Grand Marquis. The government started looking into this problem in April when the North Carolina Consumers Council filed a defect petition with the agency. Now, the inquiry has moved to the next step. According to NHTSA's documentation (as a PDF), it examined its own database and worked with Ford to come up with a total of 3,609 complaints of the front lighting control module suddenly failing. When this happens, drivers lose the low-beam headlights, but the high-beams can be used by holding the stalk. Sometimes turning the switch off and on fixes the issue. Additionally, there are 15 allegations of crashes, and one reported shoulder injury. NHTSA's preliminary evaluations "evaluate the scope, frequency, and consequence of the alleged defect" and don't necessarily lead to a recall. NHTSA looked into this problem once before in 2008 and 2009 and decided that a recall wasn't necessary. Ford also extended the warranty on the front lighting control module for these vehicles. INVESTIGATION Subject : Loss of headlights Date Investigation Opened: AUG 10, 2015 Date Investigation Closed: Open NHTSA Action Number: PE15028 Component(s): EXTERIOR LIGHTING All Products Associated with this Investigation Vehicle Make Model Model Year(s) FORD CROWN VICTORIA 2003-2005 MERCURY GRAND MARQUIS 2003-2005 Details Manufacturer: Ford Motor Company SUMMARY: After receiving a defect petition (DP15002) concerning the loss of headlights and other exterior lighting in model year (MY) 2003-2005 Ford Crown Victoria and Mercury Grand Marquis vehicles, the Office of Defects Investigation (ODI) analyzed Vehicle Owner Questionnaire (VOQ) complaints received from consumers and identified a total of 605 reports (for all submission dates) alleging headlight failure. The complaints indicate failures of both low beam headlights typically while driving, a defect condition that was evaluated under a prior ODI investigation (PE08066). Most consumer VOQs indicate that the headlights failed suddenly and without warning leaving the driver with no forward lighting, however some report the headlights flickered or dimmed prior to turning off. In some cases drivers were able to turn the headlights back on after a period of time while others reported the headlights would not come back on at all.
