NHTSA closes Ford F-150 EcoBoost acceleration probe

Typically when we report on the findings of an investigation from the National Highway Traffic Safety Administration, it's because the government body has discovered a safety issue and prescribed a recall. In this case, however, NHTSA has closed an investigation into a reported performance deficit without ever getting to the recall stage.
The issue revolves around the Ford F-150 - specifically those equipped with the 3.5-liter EcoBoost engine - of which some 360,000 were built in the 2011, 2012 and 2013 model years. After receiving an initial 95 complaints, NHTSA opened an investigation last May - almost a year ago - into the reported issue of reduced engine power under hard acceleration. The agency has since received a total of 525 such complaints, and Ford itself reported receiving over 4,000.
Together, NHTSA and Ford determined that the problem resulted from cylinders misfiring, an issue itself stemming from water getting into the charge air cooler (CAC) mated to the turbochargers. In particularly humid or rainy conditions, water was found to get into the CAC, causing some of the cylinders to misfire, which in turn triggered the ECU to disable those cylinders in order to protect the catalytic converter from damage.

2015 Ford Mustang EcoBoost

Earlier this week, Ford invited us to Charlotte, NC, to ride in an all-new 2015 Mustang fitted with its turbocharged 2.3-liter EcoBoost four-cylinder. It's the first forced-induction, four-cylinder ponycar for the Blue Oval since the sun set on the 1986 Mustang SVO. We jumped at the opportunity, as only a handful of people have ever been in the passenger seat of this new car, and most automotive media won't get as close as we did until this fall.
As we revealed in our Deep Dive, Ford will slot this new turbocharged four as premium powerplant between its naturally aspirated 3.7-liter V6 and the naturally aspirated 5.0-liter V8. At last mention, the automaker said the direct-injected, all-aluminum engine will develop 305 horsepower and 300 pound-feet of torque, returning the best fuel economy of the three powerplants in the process. History buffs will note that those figures are appreciably stouter than the 200 horses and 240 lb-ft that the '86 SVO realized out of the same displacement, and the latter's figures were hugely impressive at the time. On paper, the new EcoBoost four looks to be a good fit for most owners who want to balance performance with efficiency - we were eager to see how it felt from the passenger seat.

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.
