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 Mustang-based Saleen S302 to boast as much as 640 hp

The Ford Mustang is obviously a famous performance vehicle in its own right, but it often works even better as a platform for the aftermarket to upgrade. With the all-new 2015 model just now hitting the scene, the famous tuners at Saleen are getting their improvements for the new pony car ready for the world. After recently teasing it, the specs for its fresh S302 model are officially here, along with a first look at it in profile.
Of course, the biggest question on everyone's mind is how much power the company can get from the Mustang's V8. With the 2015 V8 model rated at 435 horsepower and 400 pound-feet, Saleen expects to bump the Ford factory numbers slightly to 450 hp and 410 lb-ft in naturally aspirated form, or with the benefit of a supercharger, it will rocket the engine's output figures to 640 hp and 565 lb-ft. No matter which powerplant a buyer chooses, there are a wide variety of available final-drive ratios with a six-speed manual or automatic gearbox.
Available as either a coupe or convertible forms, Saleen will offer its S302 in three trim levels - White Label, Yellow Label and Black Label. The White Label is the only naturally aspirated one of the bunch, but it still benefits from upgrades like a new exhaust, limited-slip differential, improved suspension, heat extractor hood and rear wing.

NHTSA and Ford investigating steering issues in Crown Vic, Grand Marquis and Marauder

There may be more steering woes for the Ford Crown Victoria. The National Highway Traffic Safety Administration has opened a preliminary evaluation into the Crown Vic and Mercury Grand Marquis from the 2004 to 2007 model years and the Mercury Marauder for the 2004 and 2005 model years because the steering shaft can jam. The issue could potentially affect an estimated 500,000 vehicles.
According to the regulator, there is a possibility that the driver's side heat shield for the exhaust manifold can rust, dislodge, and then wedge into the steering shaft. If this occurs, it leads to a situation where the driver can no longer control the car.
NHTSA has received five complaints of this happening, including one alleged case with an injury. In that situation, the car was driving onto the highway, lost control and rolled over. One occupant was hurt in the accident.
