Government investigates 400,000 Ford F-150 trucks over highway acceleration problems
Affected by the preliminary investigation are 400,000 model year 2011-2013 Ford F-150 trucks equipped with 3.5L EcoBoost gasoline turbocharged direct injection engines.
According to the National Highway Traffic Safety Administration, it has received 95 reports involving cases of reduced engine power. Specifically, owners cite unexpected reduction in engine power during hard accelerations at highway speeds. One-third of these reports have occurred while attempting to overtake another vehicle in rainy or humid conditions. There have been no crashes reported in relation to the issue.
One 2011 F-150 owner said that his vehicle “shuddered and lost ability to accelerate” while attempting to pass a slow-moving vehicle.
“This has happened several times,” wrote the owner to the NHTSA. “Dealership has been unable to fix problem and has just reprogrammed computer each time. This truck is dangerous and has left me on the side of the road more than once.”
“This is a safety issue while driving due to the massive shaking and lack of vehicle power to move with traffic,” said another owner of a 2011 Ford F-150. “Took to dealer and they could replicate incident, however can't seem to diagnose problem. This should be brought to the attention of Ford Motor Co. before someone gets killed in traffic accident due to loss of vehicle power.”
Ford is aware of the problem, but has not issued a recall. The Dearborn-based automaker has, however, issued three technical service bulletins related to intermittent engine misfire during highway acceleration in certain 2011-2012 F-150 trucks.
