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.

Chevy Silverado frame twist test a marketing victory versus Ford

The pickup market is so competitive that all three major American makers are constantly trying to find a way to prove their product is the best. The new 2015 Ford F-150 is grabbing headlines at the moment by winning awards and posting segment best numbers. But in a new video, Chevrolet is taking aim squarely at the 2015 F-250 Super Duty in a battle of heavy-duty truck supremacy against the 2015 Chevy Silverado 2500HD... well, in a single metric anyway.
The big numbers from pickups often come down to payload, towing rating and fuel economy, but for this test, Chevy and Howie Long are challenging the torsional rigidity of the trucks' frames, specifically which one flexes less. Long plays the everyman here having the Chevy engineer explain what's going on in the tests. Unsurprisingly for a video on Chevy's official YouTube page, the 2500HD wins out by a good margin. The company also reports that similar results as shown here have been certified in third-party testing.
Check out the video to see the full test. While this might seem like a marketing win for Chevy, Ford isn't immune to it, either. In 2009, the Blue Oval uploaded a similar video comparing the flex under 225 pounds of weight from the bare frames of the F-150, Chevy Silverado, Dodge Ram (as it was still called at the time) and the Toyota Tundra. The results fell in the Blue Oval's favor, as you can see here.

GM, Ford, Chrysler halt some Michigan operations over natural gas shortage

WASHINGTON - General Motors said late on Wednesday it will temporarily suspend operations at 11 Michigan plants and its Warren Tech Center after a utility made an emergency appeal to users to conserve natural gas during extreme winter cold. Fiat Chrysler Automobiles also said it had canceled a shift on Thursday at both its Warren Truck and Sterling Heights Assembly plants and was considering whether it would need to cancel additional shifts. GM said it had been asked by Consumers Energy, a unit of CMS Energy Corp, to suspend operations to allow the utility to manage supply issues after extreme cold temperatures and a fire at a compressor station. It said workers were told not to report for the shifts at its Orion Assembly, Flint Assembly, Lansing Delta Township Assembly and Lansing Grand River Assembly plants, as well as other stamping and transmission plants on Wednesday evening and early Thursday. GM said it was still assessing when employees could return to work. Workers at its Warren Tech Center were also told to stay home on Thursday. In a video message posted on Facebook, CMS Energy Chief Executive Patricia Poppe said large companies, including Fiat Chrysler, Ford Motor Co and GM, had agreed to "interrupt" production schedules through Friday to tackle the issue prompted by a fire at a Michigan facility and the record-breaking cold. Poppe said the usage cuts by large businesses were not enough, and urged 1.8 million Michigan customers to turn down thermostats as much as they could to cut natural gas use in order to protect critical facilities like hospitals and nursing homes. "I need you to take action right now," she said. Ford said it had also taken steps to reduce energy use at its four Michigan plants supplied by Consumers Energy, but added the situation remained fluid. A spokeswoman said it had reduced heating levels at Livonia Transmission and Van Dyke Transmission, stopped heat treatment processes at Sterling Axle and shut down the paint process at Michigan Assembly. Consumers Energy sent an alert to mobile phones in Michigan asking residents to reduce natural gas use.
