NHTSA closes Ford F-Series Super Duty steering probe without recall

The National Highway Traffic Safety Administration's investigation into 2008 Ford F-250 and F-350 Super Duty pickups, which was originally opened last year, has now ended without a recall. NHTSA was looking into steering failures on some 336,000 trucks.
The issue rested with the steering gear - NHTSA received five complaints of failures - which was redesigned in 2005. According to the report on the matter, investigators "found evidence of broken sector shaft gear teeth and piston damage consistent with incidents of single event overload."
NHTSA investigators, however, "found no evidence of fatigue or material property defects in any of the fractures. Analysis of complaint rates by vehicle build month showed no patterns indicating potential manufacturing quality issues and no difference before and after Ford introduced design changes to the input shaft and sector shaft seals in July 2007 to address potential leak concerns," according to the report, obtained by The Detroit News.

Ford F-150 EcoBoost in NHTSA probe for acceleration issue

According to Automotive News, the National Highway Traffic Safety Administration is launching a probe into 400,000 Ford F-150 models over possible acceleration problems. According to the article, NHTSA has received 95 reports "alleging incidents of reduced engine power during hard accelerations" on 2011 to 2013 F-150 models equipped with the company's 3.5-liter EcoBoost V6 engine.
Automotive News reports that Ford has issued three technical service bulletins "related to intermittent stumble/misfire on acceleration from highway cruise in humid or damp conditions," according to the government agency's documents. About one third of the 95 reports NHTSA has received cited humid or rainy conditions when these problems allegedly occurred.
These technical service bulletins have allowed dealers to address a "condition related to moisture accumulation in the charge air cooler during extended highway cruising at constant throttle in humid or damp conditions," AN reports, citing NHTSA documents. Furthermore, the TSB outlines details for "reprogramming the powertrain control module with the latest calibration and installing a new CAC and air deflector plate."

Ford F-450 claims best-in-class towing, company abandons practice of removing items to boost payload number

The ongoing heavy-duty truck battle between Ford and Ram is showing no signs of slowing down. The Blue Oval is trying to remove at least one point of contention between the two brands by testing its 2015 F-450 Super Duty using the Society of Automotive Engineers J2807 towing standard, which Ram also uses. In the new evaluation, the F-450 is rated at a max towing capacity of 31,200 pounds. That's an identical amount as under Ford's own, previous test.
"We leave no doubt with customers that the F-450 pickup truck has best-in-class towing of 31,200 pounds - whether tested using our own internal towing standards or SAE J2807," said Raj Nair, Ford group vice president for Global Product Development, in the company's release.
At the same time, Ford is also changing how it calculates the F-450's payload. Instead of using its minimum curb weight as before, the brand is now using the truck's base curb weight. The revision lowers the pickup's rating to 5,300 pounds, compared to 5,450 pounds previously. The company said in its announcement that the reason for this is "aligning its payload rating practices with other manufacturers to make it easier for customers to compare vehicles." General Motors made a similar switch for its pickups in August.
