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.

Ford recalls 90,736 vehicles due to engine valve issue

Ford will recall 90,736 vehicles as engine intake valves in the vehicles may break while driving, the National Highway Traffic Safety Administration (NHTSA) said on Saturday. The recall impacts certain 2021-2022 Bronco, F-150, Edge, Explorer, Lincoln Nautilus, and Lincoln Aviator vehicles equipped with either a 2.7L or 3.0L Nano EcoBoost engine, the NHTSA said. According to documents posted by NHTSA and sourced from the automaker, "The engine intake valves may break while driving, which can result in engine failure and a loss of drive power." Following an investigation that started in January, 2022, Ford found 22 instances where "the engine intake valves fractured and fell into the combustion chamber of the engine causing catastrophic engine damage." The automaker's analysis continues: "Ford identified that the potential root cause of the failures was engine intake valve failure due to valves that exceeded the designed specification for hardness, were brittle, and more likely to fracture. Ford determined that this was due to the supplier’s grinding processes and the sensitivity of the intake valve material to grinding processes that were not within control specifications. The intake valve material was changed for vehicles produced after October 31, 2021." Fixing the problem will require replacement of the entire engine. "Dealers will inspect each vehicle to determine its cumulative number of engine cycles. For vehicles that do not meet the engine cycle threshold, dealers will accumulate high revolutions per minute (rpm) engine cycles per a service procedure. Engines will be replaced on vehicles that do not pass the engine cycle accumulation," Ford says.

Ford Mustang GT350 seen and heard in motion for the first time

We just recently saw our first spy shots of the next-gen hi-po Ford Mustang slated to replace the Shelby GT500, but now we're getting our first look - and listen - of prototypes captured on video. Mustang6g.com has the video (along with some different spy shots), which show that, if nothing else, SVT knows how to tune an exhaust system. The :50 mark is a good example of this, but fast-forward to around 2:00 where the driver revs the engine and really gets on the throttle hard taking off from a stop.
There's still no definitive evidence that the next-gen SVT Mustang - said to be called GT350 - will be naturally aspirated, but it sounds just as menacing as the current Shelby GT500. While the video posted below exhibits the sort of quality that is to be expected from someone driving while trying to film someone who is attempting to elude being filmed, it's still exciting to see and hear this new Mustang in motion.
