NHTSA investigating 500k Ford and Mercury cars for lighting failures

The Ford Crown Victoria and Mercury Grand Marquis might be long gone as new models in showrooms, but the National Highway Traffic Safety Administration might check them out yet again for a potential problem. At the urging of North Carolina Consumers Council, the agency may open another investigation into the front lighting control module on vehicles from the 2003-2005 model years, and NHTSA estimates the issue could affect 517,945 vehicles. If the module stops working, it can cause a complete failure of all forward lighting, including the headlights. NHTSA previously investigated the issue in 2008 and 2009 but found no need for a recall, according to Bloomberg. Ford also extended the warranty on the part to 15 years or 250,000 miles. To prompt this new request, the North Carolina Consumers Council received a letter from a woman experiencing the module's failure. Upon further investigation, the council found 604 complaints of this problem on NHTSA's website, including seven crashes. Furthermore, the group has alleged that dealers told customers that the parts to perform the replacement weren't available, despite the extended warranty. According to the government agency, "A defect petition has been opened to evaluate the issue and make a grant or deny decision." Ford spokesperson Kelli Felker tells Autoblog via email, "We will cooperate with NHTSA, as we always do." You can read the council's complete letter to the Feds in PDF format, here. INVESTIGATION Subject : Loss of headlamp/exterior lighting Date Investigation Opened: APR 01, 2015 Date Investigation Closed: Open NHTSA Action Number: DP15002 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: The Office of Defects Investigation (ODI) has received a petition from the North Carolina Consumers Council, Inc. requesting a defect investigation of an alleged defect condition resulting in headlight and/or exterior lighting failure on 2003-2005 Ford Crown Victoria and Mercury Grand Marquis vehicles. The petition letter is attached for review. The petitioner alleges a defect in the lighting control module that powers the headlights which can result in the loss of vehicle headlights and/or all exterior lighting while driving. ODI has previously investigated this issue under PE08-066 which was closed without a defect finding.

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.
